Description

  The present invention relates to an elastic warp knitted fabric, and more particularly to an elastic warp knitted fabric having a partial low elongation function.

  For example, various clothing such as foundations such as shorts, girdles, bras, body suits, lingerie and other underwear such as slips and camisole, or sportswear such as swimsuits and leotards, and other outerwear have stretchability by warp knitting. Many so-called stretch warp knitted fabrics are used.

  Conventionally, elastic warp knitted fabrics used as such garments are basically knitted using elastic yarns and inelastic yarns, and the entire knitted fabric has uniform elasticity, and fits in clothing In order to partially suppress the elongation and vary the elongation rate in consideration of the sex and the body shape correction function, it is necessary to sew another fabric to the portion that suppresses the elongation rate.

  However, as described above, it is problematic to sew another fabric as described above, because there are problems with the appearance and the feeling of wear, etc. A sex warp knitted fabric has been proposed (see Patent Documents 1 to 3 below).

  For example, Patent Document 1 discloses that, in a warp knitted fabric having elasticity that is used for clothing, the tightening force is partially changed by changing the jacquard structure and the number of elastic yarns. However, in this case, the band-like curve pattern in which the tightening force changes is due to the change in the jacquard structure, and therefore the change in the tightening force is small. It is not satisfactory in terms of body shape correction function.

  Further, Patent Document 2 discloses that in a warp knitted fabric having elasticity that is used for clothing, the stretch of the ground knitting is suppressed by inserting an inelastic yarn, and a portion that regulates the stretch is arranged in a striped pattern. It is disclosed. However, in this case, since the inelastic yarn for suppressing the elongation is introduced by the ground, a portion in which the elongation is basically suppressed only in parallel with the knitting direction can be formed, and the amount of the suppression of the elongation is small. .

Patent Document 3 discloses that a stretch function is partially added to a warp knitted fabric having stretchability by introducing and knitting an additional elastic yarn with a handle. In this case, it is a change in stretchability due to the elastic yarn introduced by the handle, and is not intended to suppress extensibility.

  Next, embodiments of the present invention will be described based on examples shown in the drawings. However, the present invention is not limited to the examples, and various implementations can be made without departing from the scope of the claims. Is possible.

  1 and 2 are schematic plan views showing a partially low-stretch stretch warp knitted fabric according to the present invention, respectively. FIG. 3 is a diagram showing an example of a basic knitting structure of the stretch warp knitted fabric according to the present invention. It is the organization chart of the lapping state which decomposed | disassembled.

  The elastic warp knitted fabric A according to the present invention includes a warp knitting machine having a plurality of ridges, and in particular, a plurality of ground knives for knitting a ground knitting by introducing elastic yarns and inelastic yarns respectively. , A plurality of knives for pattern knitting, tens or more in the case of knitting, and / or at least one jar such as jacquard jar whose movement of the guide needle is controlled by the jacquard device It is knitted by a warp knitting machine.

  That is, the elastic warp knitted fabric A basically has a ground knitted fabric (ground fabric) in which an inelastic yarn is guided by at least one ground and an elastic yarn is guided by at least one other ground. Warp knitted fabric having a stretchability in the knitted fabric warp direction or both the weft directions as a whole. It is said that. Then, a heat-fusible yarn having a melting temperature lower than that of the non-elastic yarn constituting the ground knitting is introduced by a cocoon other than the ground knitting the ground knitting, for example, a handle, and is required in clothing. By knitting with a structure including a laterally swinging portion extending over 2 wales in a predetermined pattern, the elongation rate includes the heat-fusible yarn due to the effect of fusing the heat-fusible yarn by heat treatment after knitting. The low extension part 20 which is an area | region restrained rather than the other knitted part which has no other part, ie, the normal knitted fabric part 10 which has original extensibility, is formed in the said pattern shape.

  For example, in the case of FIG. 1, in a stretchable warp knitted fabric A in which a continuous corrugated scallop 12 is formed on the knitted fabric edge and a pattern is formed on the knitted fabric portion 10, the heat-fusible yarn is knitted. The low elongation portion 20 is formed so as to form a belt-like pattern having a large curve with a predetermined width, and in the case of FIG. 2, in the elastic warp knitted fabric A similar to the above, the heat-fusible yarn The low elongated portion 20 formed by weaving is formed into a triangular shape in the form of a linear geometric pattern and a laterally elongated low elongated portion 20.

  FIG. 3 shows an example of a basic knitting structure of the stretchable knitted fabric A. In this knitting structure, the inelastic yarn 1 is mainly guided by the full set by the ground GB1, and the knitting is performed by chain knitting across the adjacent wale for each required course to prevent fraying, or the normal same Chain knitting continuously with wales, elastic yarns are guided in a full set basically by the other ground GB2 and ground GB3, respectively, and ground GB2 inserts and knitted elastic yarn 2 along the same wale. The ground GB 3 repeats inserting and knitting the elastic yarn 3 across adjacent wales every several courses, and knitting a ground knitting structure having elasticity in both directions as a whole. Jacquard is based on a structure (thin fabric) that guides a jacquard pattern thread (usually inelastic thread) 4 with one jacquard ridge PJB and inserts it over two adjacent wales. It is knitted by controlling the horizontal swinging by a combination of a structure (thick structure) inserted over 3 wales, a structure (hole structure) inserted along the 1 wale, etc. (not shown). A so-called jacquard pattern that produces a pattern based on a mesh shape is knitted. Although not shown in FIG. 3, the pattern yarn is usually introduced using a plurality of handle ridges other than the heel, and the normal knitted fabric is used as shown in FIGS. 1 and 2. A pattern 14 different from the jacquard pattern is knitted in the portion 10. The pattern may be a lace pattern, or may be a pattern that is knitted only with a pattern ridge without using a jacquard ridge. In addition, there are cases where only the jacquard pattern does not use the handle.

  In addition, the elastic yarn of the ground GB3 is not limited to the structure shown in FIG. 3, and it is possible to appropriately set a course to be oscillated, and appropriately according to a required lateral expansion / contraction force or tightening force. Can be determined. It is also possible to omit one of the ground sheets GB2 and GB3. When the ground sheet GB3 is omitted, a warp knitted fabric having elasticity only in the knitted fabric warp direction is obtained.

  And, by using at least one handle rod other than the hooks GB1, GB2, GB3, etc. for knitting the ground stitch, for example, a handle rod for introducing the handle yarn, usually a plurality of handle rods PB The heat-fusible yarn Y is introduced into a structure including a laterally swinging portion extending over 2 wales over the entire area of the low elongation portion 20 and knitted by, for example, insertion. At this time, the heat-fusible yarn Y has a predetermined pattern required for use as the garment of the stretchable knitted fabric A, for example, the pattern of the low stretched portion 20 shown in FIGS. 1 and 2. In addition, as in the example of FIG. 5, the knitting is performed by appropriately adjusting and changing the horizontal swing position and interval in the horizontal width and position of the heat-fusible yarn Y and the knitting direction. Thereby, the said low extension part 20 is formed.

  In the knitting of the heat-fusible yarn Y, by appropriately adjusting the width and position of the horizontal swing and the horizontal swing position and interval in the knitting direction, the degree of suppression of the elongation rate, that is, the strength can be set as appropriate. It can be changed stepwise or steplessly. That is, the degree of suppression of the extension ratio of the low extension portion 20 can be set as appropriate according to the extensibility (elongation) and tightening force required according to the mode of use as clothing, and the degree of extension ratio suppression. It is also possible to partially change the elongation in the region of the low elongation portion 20.

  Furthermore, the pattern shape of the low-extension part 20 is not limited to a straight line or a largely curved band shape that is continuous or partially interrupted in the knitting direction with a substantially constant width, and a band shape that is bent in a wave shape or a zigzag shape. Various shapes can be formed as appropriate depending on the use mode, such as strips with varying widths, small patterns or linear sets that are repeated or continuous, or geometric patterns. .

  For example, FIG. 4 shows a modified example of the low elongation portion 20 of FIG. 1, and two rows of low elongation portions 20 having a belt-like pattern formed by weaving heat-fusible yarns are formed, and a part of each low elongation portion 20 is formed. An example in which the shape is changed so as to form a separated shape of the plurality of narrow strip portions 21 is shown. In this case as well, the knitting can be performed by changing and adjusting the width and position of the horizontal swing of the heat-fusible yarn.

  FIG. 5 illustrates a structure in a lapping state of only the heat-fusible yarn Y in a part of the low elongation portion 20 in FIG. In the knitting structure of FIG. 5, three heat-fusible yarns Y (Y1, Y2, Y3) are individually provided one by one by three handle knives other than those knitting the knives of the stalks. The belt-shaped low-elongation portion 20 is formed by being introduced and knitted while appropriately changing the horizontal swing position, width, and interval so as to include the horizontal swing portions extending over 2 wales. . And the area | region of the said low expansion | extension part 20 is shown by the oblique line part and the diagonal grid | lattice part in FIG. A portion 20a (shaded portion in FIG. 1) having a large degree of elongation rate suppression and a small elongation in the region with respect to a normal knitted fabric portion 10 having an original elongation that does not include the heat-fusible yarn Y2, Y3 Oscillates every two courses, so that the degree of elongation rate suppression with respect to the knitted fabric portion 10 is smaller than that of the portion 20a, and the elongation in the region is slightly larger than that described above. (Slanted lattice portion). That is, the degree of suppression of the elongation rate is in two stages.

  The low elongation portion 20 of the embodiment of FIG. 2 also has a portion 20a having a small elongation by increasing the degree of elongation rate suppression with respect to the knitted fabric portion 10 having the original elongation that does not include the heat-fusible yarn. In addition, similarly to the above, it is possible to form a partition into a portion having a small elongation in the region and a middle portion having a slightly large elongation, and to change the degree of elongation rate suppression for each low elongation portion 20.

  FIG. 6 shows an example in which the degree of suppression of the expansion rate is changed in three stages in the region of the low extension part 20, and in FIG. A portion 20a having a large and small elongation in the region, a portion of the oblique lattice having a degree of elongation rate suppression slightly smaller than the above, a portion 20b having a moderate elongation in the region, and a hatched portion having a slightly rough interval between the regions. Are the portions 20c that are the smallest and the elongation in the region is slightly large. FIG. 7 shows a wrapping state structure of only the heat-fusible yarn Y in a part of the low elongation portion 20 of FIG. 6, and in the portion 20a where the elongation is small, two heat-fusible yarns Y per course. Are inserted so as to overlap each other, and in the portion 20b where the elongation is medium, one heat-fusible yarn Y is inserted horizontally for each course, and the portion where the elongation is slightly large In 20c, one heat-fusible yarn Y is laterally inserted every two courses, thereby making a difference in the degree of elongation rate suppression of each of the portions 20a, 20b, 20c.

  FIG. 8 shows a low-elongation portion 20 in the elastic warp knitted fabric A, in which a portion 20a having a smaller elongation than the normal knitted fabric portion 10 is suppressed to a circular small pattern that is a geometric pattern. In this example, the whole is arranged in a band shape. FIG. 9 shows the structure of the wrapping state of only the heat-fusible yarn Y in a part of the low elongation portion 20 of FIG. 8, and the change in the swing width and the swing position of the heat-fusible yarn Y are changed. Thus, the portion 20a having a small elongation is formed in a small pattern. In this case as well, the degree of elongation rate suppression of the portion 20a having a small elongation can be set as appropriate.

  FIG. 10 shows, as a low elongation portion 20 in the elastic warp knitted fabric A, a linear portion of a portion 20a having a smaller elongation than the normal knitted fabric portion 10 and having a smaller elongation rate, and the linear shape as a whole. An example in which a set is arranged so as to form a belt shape is shown. FIG. 11 shows a structure in a lapping state of only the heat-fusible yarn Y in a part of the low elongation portion 20 due to the linear assembly. For example, the heat-fusible yarn Y is applied to a plurality of handle ridges. Arranged at several wale intervals, each heat-fusible yarn Y is basically inserted straight along the wale in the warp direction (knitting direction), and is swung to the wale adjacent to one side for each required course. By repeating the transition, a linear pattern that forms a predetermined pattern that is linear and largely curved is formed. Also in this case, the heat-fusible yarn Y is knitted with a structure including a laterally swinging portion extending over 2 wales in a predetermined course.

  In the above-described embodiment, a plurality of heat-fusible yarns Y are individually introduced by a plurality of handle rods (the embodiment shown in FIGS. 1 to 11), and 2 wales or more are required for each course. However, as described above, it is also necessary to introduce and knit the heat-fusible yarn Y with a ground cloth other than the ground cloth for knitting the ground knitting. In this course, it is possible to form and knit at least a part of the stitch while swinging over two or more wales, or to knit by combining insertion and stitch formation.

  For example, FIG. 12 to FIG. 14 show examples in which the heat-fusible yarn Y is introduced and knitted by ground other than the ground for knitting the ground knitting, each of which includes a plurality of heat-fusible yarns Y. Are guided by the same ground and perform the same lateral movement. In FIG. 12, the heat-fusible yarn Y is knitted by insertion. FIG. 13 shows a case where the heat-fusible yarn Y is knitted by forming stitches in all courses while being swayed over 2 wales or more in a required course, and FIG. 14 shows the heat-sealing. The case where the part which knits the sex yarn Y by insertion and the part which forms the stitch and knits is knitted by the same ground is shown. In either case, the heat-fusible yarn Y may be partially included in the same wale.

  Also in the case of introducing the heat-fusible yarn Y with a handle, it is possible to form and knit at least part of the stitch as in the above while swaying over 2 wales or more in a required course, that is, in all courses. As for the knitting by forming the stitch, the portion to be knitted by insertion and the portion to be knitted by forming the stitch can be knitted with the same heel.

  In addition, in the low elongation portion 20 by the knitting of the heat-fusible yarn Y, an inelastic yarn for preventing breakage of the heat-fusible yarn and / or improving the texture can be knitted together (not shown). ). In this case, in addition to knitting the inelastic yarn as a composite yarn twisted together with a heat-fusible yarn, it is also possible to knitting the same guide needle together with two heat-fusible yarns. It is also possible to knit using a different kite.

  Further, in the elastic warp knitted fabric A, a floating portion 5 made of an inelastic yarn is knitted at least on the back surface side of the low elongation portion 20 as in the knitting structure of FIG. And at least the texture and touch feeling of the back surface of the low elongated portion 20 can be improved, which is preferable. The inelastic yarn free portion 22 can also be formed in the normal knitted fabric portion 10. Further, for example, by forming a free portion 22 using polyurethane yarn or rubber yarn for the floating yarn 5, the free portion 22 can be used as a slip stopper.

  Furthermore, the elastic warp knitted fabric A of the present invention is not shown, but separately from the low elongation portion 20 by the heat-fusible yarn Y, a low elongation portion by knitting a normal inelastic yarn, It can also be provided on the same ground.

  In the elastic warp knitted fabric, as the inelastic yarn for knitting the ground knitting, nylon yarn and other various synthetic fiber yarns or natural fiber yarns such as wool, silk, and cotton can be used. In addition, as the elastic yarn of the ground knitting, polyurethane yarn and other various elastic yarns can be used. In practice, with respect to the elastic yarn to be oscillated, various elastic covering yarns such as polyurethane yarns are used as cores in view of the fact that the oscillating portion appears on the front side of the knitted fabric in the same manner as the pattern yarn and the texture of the back surface is improved. An elastic covering yarn obtained by covering a nylon processed yarn as a yarn is preferably used. About the fineness of these yarns, it can set suitably according to the use as clothing of warp knitted fabric.

  Further, in the heat-fusible yarn Y of the present invention, at least a part of the components has a melting temperature lower than that of the non-elastic yarn constituting the ground knitting and lower than the melting temperature of the inelastic yarn (for example, several Ten degrees is a fiber yarn made of a heat-fusible component that is melted or softened by heat at the time of heat treatment such as heat setting at a low temperature to express a fusing property, or a heat-fusible yarn containing the fiber. This heat-fusible yarn Y can be introduced alone or as a composite yarn twisted with other ordinary inelastic yarns. It can set suitably according to the effect of a rate control, a use, etc.

  The melting temperature of the yarn of the heat-bonding component fiber varies depending on the melting temperature of the inelastic yarn, but when the melting temperature of the inelastic yarn is 215 ° C to 220 ° C, for example, 135 ° C to 165 ° C, It can be melted or softened by heat by heat treatment at around 180 ° C. after knitting.

  By knitting the heat-fusible yarn Y, after knitting, a temperature lower than the melting temperature of the inelastic yarn constituting the ground knitting and higher than the melting temperature of the heat-fusible yarn Y, for example, around 180 ° C. When heat treatment such as heat setting is performed at a temperature, the heat-fusible yarn Y is melted and fused to inelastic yarns or elastic yarns constituting other ground knitting, and as a result, knitting with elastic yarns. Low stretch portion 20 in which stretchability in the ground warp direction or in both the weft directions, particularly stretchability is suppressed, and the stretch rate is moderately suppressed as compared with a normal knitted fabric portion 10 in which a heat-fusible yarn is not knitted. Will be formed.

  In particular, since the heat-fusible yarn Y is knitted in a structure including a laterally swinging portion that extends over 2 wales, the heat-fusible yarn is knitted without being swayed along the same wale. As compared with the case of only the case, the extensibility can be facilitated and effectively suppressed, and the change in the elongation rate can be set larger than that of a normal knitted fabric portion. In addition, the degree of extensibility suppression can be changed in the low elongation portion 20 by adjusting the weaving form such as the swing width and interval of the heat-fusible yarn and partially changing the fineness.

  Therefore, in the elastic warp knitted fabric A of the present invention, the stretch rate and shape of the low stretch portion 20 are set according to the usage in various underwear for women such as shorts, girdle and brassiere. By doing so, the low-extension part 20 can satisfactorily exhibit the function of improving fit and body shape correction, and can be suitably used for these applications.

  For example, FIGS. 16 and 17 show an example in which each elastic warp knitted fabric A of FIGS. 1 and 2 is used in the back body and the front body of the shorts. In this case, the large curve of FIG. 1 is formed. The low-extension part 20 has a shape extending to the lumbar side part along the lower line of the hip part, thereby exhibiting a hip-up function adapted to the body shape of the hip, and the triangular low-extension part 20 of FIG. Corresponds to the abdomen, so that it plays the role of holding the abdomen.

  In addition, as shown in FIG. 18, when the elastic warp knitted fabric A is used for a brassiere, the low elongated portion 20 is formed in a curved shape along the lower edge of the cup portion. The bust-up function can be demonstrated.

  The basic organization of the ground knitting is not limited to the illustrated embodiment, and various knitting organizations such as a satin knitting, a denvi knitting, and a plain cord knitting can be used. It is also possible to change the organization.

[Comparison test]
In order to verify the stretch rate and stretch recovery rate of the low stretch portion of the stretch warp knitted fabric of the present invention described above, a knitted fabric that does not contain a heat-fusible yarn (basic knitted fabric) is used as a basis. A comparison was made between the knitted fabric corresponding to the low stretched portion knitted with the adhesive yarn (Example) and the knitted fabric knitted with the normal inelastic yarn (Comparative Example) through the elongation rate test and the elongation recovery rate test. .

(Basic knitting fabric)
Using a KARL MAYER Russell machine (MRSSJ78 / 1, 24 gauge) as a warp knitting machine, a 44 dtex / 10f nylon yarn is introduced as a jacquard yarn PJB in FIG. 3 and inelastic by a ground GB1 44dtex / 10f nylon yarn is introduced as yarn, 310dtex polyurethane yarn is introduced as elastic yarn by ground GB2, and 78dtex is usually used as elastic yarn by ground GB3 and 22dtex polyurethane yarn as core yarn An elastic covering yarn covered with a nylon yarn having a melting temperature of 5 mm is introduced, and a knitted fabric from which the heat-fusible yarn is removed based on the knitting structure of FIG. Organized.

  In the dyeing process after knitting, the obtained knitted fabric is subjected to a finishing treatment (heat treatment) at a heat set temperature of 180 ° C., and a finishing course of 100 courses / inch and a finished wales of 35 wales / inch are elastic warp knitted fabrics. It was. Using the obtained warp knitted fabric as a basic knitted fabric sample, the following elongation rate test and elongation recovery rate test were performed. The results are shown in Table 1 below.

(Example)
In addition to the basic knitted fabric, a heat-fusible yarn which is a 56 dtex nylon yarn having a lower melting temperature (135 ° C. to 165 ° C.) than the inelastic yarn of the base fabric and a normal melting of 155 dtex The composite yarn twisted with the nylon yarn of the temperature was introduced by a plurality of handle ridges PB, and knitted in the same manner as the basic knitted fabric by inserting and knitting it across 10 wales for each course of FIG. .

The obtained knitted fabric is subjected to a finishing process after knitting in the same manner as the basic knitted fabric, and the heat-fusible yarn is melted and softened, and a low-extension portion that suppresses extensibility with respect to the basic knitted fabric is provided. Formed.
Using the obtained warp knitted fabric of the low stretched portion as a sample of the example, the following stretch rate test and stretch recovery test were performed as described above. The results are also shown in Table 1 below.

(Comparative example)
As a comparative example, the same procedure as in the above example was performed except that a nylon-processed yarn having a normal melting temperature of 235 dtex was introduced into a plurality of handle ridges in place of the yarn containing the heat-fusible yarn forming the low elongation portion. The obtained knitted fabric was subjected to the same finishing treatment, and the obtained warp knitted fabric was used as a sample for a comparative example, and the following elongation rate test and elongation recovery test were performed as described above. The results are also shown in Table 1 below.

(Elongation rate test)
The basic knitted fabric and each of the knitted fabrics of the examples and comparative examples are attached to a Tensilon type tensile tester with a width of 2.5 cm and a gripping interval of 10 cm in both directions of warp, stretched at a tensile speed of 30 cm ± 2 cm / min, and a load of 9.8 N (Newton), elongation at 14.7N, 22.1N was measured.

(Elongation recovery rate test)
Similar to the elongation test, the warp only test was attached to a Tensilon type tensile tester with a width (weft direction) of 2.5 cm and a gripping interval (passage direction) of 10 cm, and a set elongation of 80% at a tensile speed of 30 cm ± 2 cm / min. The length at the time of extending to the original state was measured, and the recovery rate was calculated by the following formula.

  Elongation recovery rate (%) = (set extension dimension−sag length after extension) ÷ set extension dimension × 100

  As a result of the above test, as for the elongation rate, in the warp direction, in the case of the example, the elongation rate is greatly reduced as compared with the comparative example, and the elongation is low, which is nearly half of the basic knitted fabric. Further, in the weft direction, in the case of the example, the elongation rate decreases to nearly half that of the comparative example, and the elongation is as low as about 1/10 of the basic knitted fabric.

  As for the elongation recovery rate, in the case of the example, compared to the basic knitted fabric and the comparative example, the set elongation is the same, but the applied load is very severe (exceeds 22.1N). In some cases, the recovery rate is slightly inferior, but there is no significant difference, and there is no problem in use.

  Therefore, as in the present invention, it is particularly effective to improve the fit and use the body shape correction function in use as clothing by knitting a heat-fusible yarn to form a low stretched portion.

  The partially low stretch stretch warp knitted fabric of the present invention can be suitably used for foundations such as shorts, girdles and brassieres, lingerie such as slips and camisole and other underwear for women, sportswear and outerwear.
