Description
Technical Field
The invention relates to the technical field of textile fabrics, in particular to a light moisture-absorbing breathable I-level arc-proof fabric.
Background
Operating personnel in industries such as electric power, fire fighting and the like often face electric arcs, thermal effect, shock wave and strong ultraviolet generated in the moment of the electric arcs threaten the safety of personnel, and the serious personnel are threatened by the injury of the light personnel and the life of the serious personnel. The general technical requirements of the personal arc protection article are specified in DL/T320-2010 standard: for example, people facing arc energy not less than 6.15cal/cm2 or people possibly entering an arc hazard area need to be equipped with corresponding arc protection articles. When the electric arc energy is in the range of 6.15cal/cm 2-8 cal/cm2, the hazard level is I level. The working environment generally comprises outdoor ground operation and aerial operation in the power industry, such as uninterrupted electrolysis head operation and head lapping operation, closed power distribution cabinet test and other operations, the strength is high, the sweat amount is high, the heat stress problem is easy to generate, the physical and mental health of operators is influenced, and the working efficiency is seriously reduced; working personnel wear the arc protection clothes throughout the year in the hot and humid weather in south, and the arc protection clothes with light weight, moisture absorption and air permeability are needed.
Currently, the indexes for measuring the arc protection capability of fabrics are ATPV value and Ebt value. The ATPV value is the thermal radiation protection value of the arc resistant fabric, meaning that there is a 50% probability that the energy incident on the material will be sufficient heat to penetrate the sample to cause a second degree burn; the Ebt value is the arc protection rupture value of the arc protection fabric, meaning that there is a 50% probability of energy incident on the material rupturing the test specimen, and the total area of the resulting breaches in the fabric exceeds 1.6cm 2. According to the requirements of DL/T320-2010, the I-class arc-proof fabric must simultaneously satisfy: the material is flame retardant essentially, the ATPV value is 6.15cal/cm 2-8 cal/cm2, the Ebt value is 13cal/cm 2-18 cal/cm2, and the fabric areal density is less than or equal to 200g/m 2.
The research shows that: the protective performance of the arc-proof fabric depends on the thermal protective performance and the mechanical protective performance of the material to a great extent and is also related to the gram weight of the fabric, and the larger the gram weight is, the better the arc-proof performance is. In the prior art, the fabric with high electric arc prevention grade is usually an intrinsic flame retardant material, and has high gram weight, thick yarn and high density. Due to the fact that intrinsic flame-retardant materials such as aramid fibers 1313, aramid fibers 1414 and the like are high in initial modulus, strong in rigidity, hard in hand feeling and poor in moisture absorption, the contradiction between the protection performance and the comfort performance in the design of the electric arc preventing fabric is caused.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, so that those skilled in the art can better understand the advantages and features of the present invention, and thus the scope of the present invention is more clearly defined. The embodiments described herein are only a few embodiments of the present invention, rather than all embodiments, and all other embodiments that can be derived by one of ordinary skill in the art without inventive faculty based on the embodiments described herein are intended to fall within the scope of the present invention.
Referring to fig. 1-3, a lightweight moisture-absorbing breathable class i arc-resistant fabric is formed by interweaving warp yarns 1 and weft yarns 2, wherein the warp yarns 1 and the weft yarns 2 are composed of the following components in percentage by mass: 50-65% of modacrylic fiber 3, 25-35% of aramid fiber 1313, 5-15% of aramid fiber 1414 and 2% of conductive fiber 6, wherein the sum of the mass percentages of the components is 100%;
the electric arc prevention fabric is characterized in that fibers from outside to inside are sequentially distributed from thick to thin, and the electric arc prevention fabric is sequentially distributed from outside to inside and comprises modacrylic fiber 3, aramid fiber 1313 fiber 4, conductive fiber 6 and aramid fiber 1414 fiber 5.
In the embodiment, the arc-proof fabric adopts the synergistic effect of four fibers such as modacrylic, aramid 1313, aramid 1414 and conductive fiber, so that the balance of protection and comfort is achieved. The modacrylic fiber has good flame retardant property, soft hand feeling and good comfort, and generates a large amount of smoke gas to isolate oxygen in the air during combustion; the aramid 1313 fiber has good high temperature resistance, good dimensional stability, strong spinnability, high fire resistance and corrosion resistance, high breaking strength and large elongation, and is beneficial to improving the integral strength of the fabric; the aramid 1414 fibers have excellent flame-retardant high-temperature resistance and high strength, do not shrink and deform when exposed to high temperature, can still play a skeleton role after being combusted, and can greatly improve the material rupture threshold Ebt of the arc-proof fabric; the conductive fiber has an antistatic effect and improves the processability during spinning and weaving.
Specifically, the titer of the modacrylic fiber is 2-2.5D, the titer of the aramid 1313 fiber is 1.5-2D, the titer of the aramid 1414 fiber is 0.9-1.2D, and the titer of the conductive fiber is 1.5D. The electric arc preventing fabric has different fiber thickness distribution rules in the ring yarn structure, the thicker fiber is distributed in the outer layer, the thinner fiber is distributed in the core layer, and thus the electric arc preventing fabric has the fiber distribution from outside to inside of modacrylic fiber, aramid fiber 1313 fiber, conductive fiber and aramid fiber 1414 fiber.
Specifically, the weave structure of the arc-proof fabric is plain square grid fabric or 2/1 twill square grid fabric, and the square grid distance is 3-5 mm.
In this embodiment, the arc-proof fabric has a compact structure with a fabric structure near the support surface such as warp and weft, the warp and weft preferably have the same thickness and the same density, and the warp and weft together form the support surface of the fabric. When electric arcs occur, compared with fabrics of a warp supporting surface and a weft supporting surface, the fabrics of the warp supporting surface and the weft supporting surface have the most explosive surface yarn distribution, the uniform distribution of the warp and weft yarn tissue points can reduce the damage of the fabrics caused by excessive damage of the warp and weft yarns, and the thickness difference and the density difference of the warp and weft yarns are controlled to be 0-15%. Thus, a plain weave grid or 2/1 twill weave grid is used, with a grid spacing of 3-5mm, with the warp and weft grid yarns each being two separate yarns.
Specifically, the arc-proof fabric is prepared by sequentially carrying out yarn spinning, dyeing, grey cloth weaving, desizing, tentering, preshrinking and finished product rolling;
the yarn spinning sequentially comprises raw material pretreatment, cotton grabbing, cotton mixing, cotton opening, cotton feeding, coiling, cotton carding, drawing frame (three paths), roving, spinning, spooling, doubling, double twisting and yarn steaming (heat setting). The antistatic oiling agent and the metal groove drum are used, and the processes of light quantification, heavy pressurization and the like are used, so that the problems of poor mixing uniformity of multi-component fibers, serious aramid fiber static phenomenon and the like are solved.
In the dyeing step, 10-15g/L of anhydrous sodium sulphate, 4-5 PH, 95 ℃ and 40-60min of heat preservation time are adopted.
In the desizing step, active desizing enzyme is adopted for treatment and drying.
In the tentering step, the temperature is 160-170 ℃.
During the processing of the arc-proof fabric, soft blended yarn with thicker diameter is manufactured by a low-torque spinning technology, and a mechanical false twisting device is arranged between a front roller and a yarn guide hook of a ring spinning frame, so that the fiber control and false twisting efficiency is improved; the synchronous control technology of the false twisting device and the ring spinning frame realizes the technical matching of the false twisting device and the ring spinning frame, and solves the problems of difficult false twisting application, unstable false twisting, easy broken fiber strands, much filoplume and the like. The twist factor is 180-200, and the yarn is soft, fluffy, large in diameter and high in strength.
Specifically, the density of the arc-proof fabric prepared by the process is less than or equal to 200g, the thickness is 0.34-0.38mm, the fineness of the warp and weft yarns is 16.9-22.7tex, the density of the warp yarns is 222-252/cm, the density of the weft yarns is 200-220/cm, the TPP value of the fabric is 423-512 kw.s/m 2, the air permeability is 214-252mm/s, the moisture permeability is 1770-1850g/m 2.24 h, the warp damage length is 54-66mm, the weft damage length is 64-75mm, the flame retardant time is 0 second, the afterflame retardant time is 0 second, the warp breaking strength is 750-814N, the weft breaking strength is 557557-716N, the warp tearing strength is 30.6-39.1N, and the weft breaking strength is 30.6-41.1N. Meanwhile, the arc-proof fabric has the characteristics of heat resistance, flame retardance, no combustion supporting, no melting and the like, and can be rapidly expanded and carbonized when arc explosion occurs, so that the density of the arc-proof fabric is increased and thickened, and a protective layer is rapidly formed, so that the contact damage of human skin and arc heat energy is minimized.
