Description

Technical Field

[0001] The invention relates to the technical field of textile production, in particular to an anti-static and flame-retardant micro-elastic fabric and a manufacturing process thereof. Background Art

[0002] In modern society, with the increasing popularity of various electrical equipment, fires caused by electrical failures are increasing. In addition, various man-made or natural disasters occur frequently. The fire accidents caused by various disasters are extremely harmful, which makes the market's requirements for flame retardancy of textiles more and more extensive. In recent years, the state has also issued mandatory standards for flame retardancy of workwear for special industries. Due to the specificity of use and application limitations, flame retardant textiles are in short supply in the market. At the same time, the price of flame retardant textiles is relatively expensive, and the wearing comfort is also poor. For firefighters and special engineering personnel who use them frequently, they need to wear them for a long time. In addition to better flame retardancy, their comfort also needs to be improved. The present invention is committed to developing a product that takes both comfort and flame retardancy into consideration. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an anti-static flame-retardant micro-elastic fabric and a production process to meet the special requirements of flame-retardant textiles and take into account the comfort and flame retardancy of the clothing.

[0004] To achieve the above-mentioned purpose of the invention, the present invention adopts the following technical scheme: an anti-static flame-retardant micro-elastic fabric, which is composed of flame-retardant viscose fiber, flame-retardant aramid fiber, spandex filament, and conductive fiber. The mass percentages of the above raw materials are: flame-retardant viscose fiber 50-65%, flame-retardant aramid fiber 25-40%, spandex filament 2-8%, and conductive fiber 3-7%; the fabric is a twill fabric made of non-elastic yarn and micro-elastic yarn.

[0005] Furthermore, the flame-retardant aramid fiber is solution-dyed aramid fiber.

[0006] Furthermore, the non-elastic yarn is composed of flame-retardant viscose fiber, flame-retardant aramid fiber, and conductive fiber, and the slightly elastic yarn is composed of flame-retardant viscose fiber, flame-retardant aramid fiber, spandex filament, and conductive fiber.

[0007] Furthermore, the warp and weft yarn counts of the non-elastic yarns are 32 s -40 s , the warp and weft yarn count of the slightly elastic yarn is 32 s -40 s .

[0008] Furthermore, the fabric specification is 32 s -40 s / 2x 32 s -40 s / 2 98x102 2 / 1 right twill fabric, width 153 cm; weight per square meter 160-240 g / m 2 .

[0009] A manufacturing process of an anti-static flame-retardant micro-elastic fabric comprises the following steps:

[0010] (1) Production of non-elastic yarn: Preparation of raw sliver: Aramid fiber and conductive fiber are mixed in a mixing ratio before the cotton cleaning process, and then troughed on the disc cotton grabber of the cotton opener, and then through the cotton cleaning process, a cotton roll is made. The dry weight of the cotton roll is 330 g / m and the length is 30 m. Because the aramid fiber has poor cohesion and high static electricity, the process principle of light quantitative, heavy pressure and light blow is adopted; the cotton roll is fed into the carding machine, the dry weight of the raw sliver is 15 g / 5 m, the cylinder speed is 260 rpm, the needle speed ratio is 2.0, and the carding adopts the process principle of soft combing and slow speed;

[0013] (2) Production of micro-elastic yarn: Preparation of raw sliver: Aramid fiber and conductive fiber are mixed in a mixing ratio before the cotton cleaning process, and then troughed on the disc grabber of the cotton opener. After the cotton cleaning process, the cotton roll is made into a cotton roll with a dry weight of 330 g / m and a length of 30 m. Since the aramid fiber has poor cohesion and high static electricity, the process principle of light quantitative, heavy pressure and light blow is adopted; the cotton roll is fed into the carding machine, the raw sliver dry weight is 15 g / 5 m, the cylinder speed is 260 rpm, the needle speed ratio is 2.0, and the carding adopts the process principle of soft combing and slow speed;

[0014] The second preparation of raw sliver, flame-retardant viscose fiber, is grooved on the blow room disc, and then goes through the blow room process to make cotton rolls. The dry weight of the cotton rolls is 360 g / m and the length is 30 meters. Because viscose fiber has good spinnability but low wet strength, the humidity of the blow room combing is controlled at 50-60%; the cotton rolls are fed into the carding machine, the dry weight of the raw sliver is 18 g / 5 meters, the cylinder speed is 280 rpm, the needle speed ratio is 2.2, and the carding adopts the process principle of soft combing and slow speed;

[0015] In the rough drawing process, the raw sliver 1 and raw sliver 2 are mixed according to the blending ratio, and the rough yarn is drawn by three steps, the rough yarn is 4.0 g / 10m, the twist coefficient is 82, and the process principle of heavy pressure and slow speed is adopted;

[0016] The fine yarn is core-spun compact yarn, yarn count 32 s -40 s , spandex filament specification 40D, draft coefficient 1.7 times, twist coefficient 390;

[0017] (3) Fabric production: Fabric specifications 32 s -40 s / 2x 32 s -40 s / 2 98x102 2 / 1 right twill fabric, width 153 cm, non-elastic warp yarns are warped in batches, with a total of 5500 warp roots during warping. The tension of each warp beam is controlled during warping to ensure uniform tension of the warp beams; micro-elastic warp yarns are warped in batches, with a total of 1500 warp roots during warping. The tension of each warp beam is controlled during warping to ensure uniform tension of the warp beams; reeding process: the number of ground tissue insertions is 2, 3, the number of side tissue insertions is 3, 36 on the left and right, and the side tissue insertions are: 1,1,2,2 (3); weaving adopts double warp beams, the weaving tension of non-elastic warp yarns is 500cn, and the weaving tension of micro-elastic warp yarns is 700cn; the weft yarns are divided into non-elastic weft yarns and micro-elastic weft yarns, and the density is sprayed in batches according to 8:1.
