Problems solved by technology

However, the strength of nanofiber yarns is low at present and cannot be directly used in textile processing, and there is no effective method to improve the strength of nanofiber yarns. Therefore, there is no research on nanofiber fabrics at home and abroad to improve the hydrophilicity of chemical fiber fabrics.

Embodiment 1

[0029] (1) Preparation of high-strength nanofiber yarn

[0030] Four polyamide 6 (PA6) nanofiber bundles (each 45dtex) are unwound from the unwinding roller 1 at a speed of 1m / min, passed through the combining roller 3 and merged into a nanofiber bundle, and then passed through the guide roller 5, The immersion roller 6 and the guide roller 8 make the nanofiber bundle fully swell in the liquid tank 7 (the swelling solution is a mixed solution of formic acid and ethanol, and the mixing mass ratio is 1:2), and then the pulling roller pair 9 is 1.8m / min at a speed of traction to form the first stretch reinforcement (stretch ratio is 1.8). Then the nanofiber bundle passes through the heating device 10 at a speed of 3.2 m / min under the traction of the pulling roller pair 11 (the heating device is 20 cm long, the heating plate spacing is 5 mm, and the temperature is 150 ° C), so the second stretching ratio is 1.8 times . Then the nanofiber bundle is wound on the winding roller 13...

[0051] (1) Preparation of high-strength nanofiber yarn

[0052] With embodiment 1.

[0053] (2) Weaving

[0054] Nanofiber yarns (two sizing yarns combined for weaving, the linear density of each sizing yarn is 88dtex) are selected as the warp and weft yarns, and the GA391 vertical single-yarn sizing machine (Jiangyin Tongyuan Textile Machinery Co., Ltd.) is used before weaving on the machine. ) for sizing, and then warping with SGA191 single-yarn warping machine (Sheyang Textile Machinery Factory), and weaving plain weave nanofiber fabric with C / 401 rapier loom (Tianjin Longda Co., Ltd.). The weaving parameters are: the warp density of the upper machine is 450 pieces / 10cm, the weft density of the upper machine is 250 pieces / 10cm, the width is 24cm, the reed number is 15, and the number of penetrations is 3.

[0055] The warp and weft yarns of the comparison fabric are nylon 6 filaments (two combined weaving, the filament specification is 88dtex / 24f), and all other process p...

Abstract

The invention provides a one-step nanofiber yarn reinforcement method and a hydrophilic chemical fiber fabric thereof. In the one-step nanofiber yarn reinforcement method, a plurality of nanofiber bundles are combined and fully immersed in liquid to swell, and the first stretching is performed. Reinforcement, after passing through the heating device, the second stretching reinforcement is carried out, and then the third stretching reinforcement is carried out; at the same time, twist is applied to the nanofiber yarn. The present invention combines swelling stretching, thermal stretching, and twisting three reinforcement methods together to realize one-step reinforcement, making the whole process simple to operate and high in reinforcement efficiency.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a one-step nanofiber yarn reinforcing method and a hydrophilic chemical fiber fabric. Background technique [0002] Chemical synthetic fiber (chemical fiber) fabrics (such as polyester, nylon, acrylic, etc.) are widely used in clothing, home textiles and other fields due to their bright colors, not easy to deform, good durability, high output and low price. However, the disadvantages of chemical fiber fabrics such as poor hydrophilicity, poor air permeability, and easy generation of static electricity limit its application in high-grade textiles. At present, there are mainly three ways to improve the hydrophilic properties of chemical fiber fabrics: 1) Improve the performance of chemical fiber fabrics by blending chemical synthetic fibers and natural fibers. Blended fabrics not only absorb the respective advantages of natural fibers and chemical synthetic fibers, but...
