Problems solved by technology

But the only regret is the water absorption and dehumidification function, because the chemical fiber silk belongs to the macromolecular structure of petroleum refining, and the water absorption and dehumidification function cannot surpass natural fibers.

Embodiment 1

[0026] A 100D polyester filament that can increase the function of water absorption and moisture release.

[0027] In the first step, the 100D polyester filament is added to 26T / cm on the basis of 16T / cm according to the technical requirements of the customer, and the twist is S twist.

[0028] In the second step, the hydrolyzable polyester yarn 50D and the twisted 100D, 26T / cm, S twisted polyester yarn are twisted in the Z direction to add 10T / cm, and the Z direction is stranded.

[0029] In the third step, twisting 100D polyester filaments and strands twisted with 50D hydrolyzable polyester filaments is subjected to high-temperature and high-pressure shaping at a temperature of 120° C. for half an hour.

[0030] In the fourth step, the hydrolyzable polyester filaments in the strands are hydrolyzed.

[0031] Use 5g / L of 98% caustic soda, 0.4g / L of silk-removing agent DYT, and 0.5g / L of acetic acid to form a solution with a ratio of 1:15.

[0032] Put the strands into the aq...

Embodiment 2

[0035] A polyester taffeta with increased moisture wicking properties.

[0036] The first step is to add 50D polyester filament S twist to 28T / cm on the basis of 18T / cm and S twist according to customer requirements.

[0037] In the second step, the 45D hydrolyzable polyester filament and the twisted 50D, 28T / cm, S-twisted polyester filament are twisted 10T / cm in the Z direction and formed into strands.

[0038] In the third step, the strands are subjected to high temperature and high pressure setting at a temperature of 120° C. for 45 minutes.

[0039] The fourth step is to weave the strands into cloth according to the technical requirements of polyester taffeta.

[0040] The fifth step is to hydrolyze the hydrolyzable polyester filaments in the woven gray cloth.

[0041] Use 2g / L of non-ionic hydrogen peroxide stabilizer, 6g / L of hydrogen peroxide with a concentration of 27.5%, 6g / L of caustic soda with a concentration of 98%, 0.4g / L of silk-removing agent DYT, and 0.1g / L ...

Abstract

The invention provides a method capable of increasing water absorption and moisture removal functions of chemical fibers, and belongs to the technical field of textiles. The method is characterized inthat chemical fiber yarns are twisted and then reversely twisted with hydrolysable polyester yarns to form plied yarns for shaping, and then the hydrolysable polyester yarns are subjected to hydrolytic finishing, or the chemical fiber yarns are twisted and reversely twisted with the hydrolysable polyester yarns to form the plied yarns for shaping, then the plied yarns are woven into cloth, and then the hydrolysable polyester yarns in the cloth are subjected to hydrolytic finishing. According to method, through the principle that the chemical fibers are fluffy due to doubling hydrolysis of thechemical fibers and the hydrolyzable polyester yarns, the chemical fibers can longitudinally form spiral holes and spiral grooves, and capillary siphon can be generated, so that the water absorptionand moisture removal functions of the chemical fibers are increased.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for increasing the water absorption and dehumidification function of chemical fiber filaments. Background technique [0002] With the progress of society and the improvement of people's living standards, people are paying more and more attention to clothing and home textiles that everyone pays attention to. Instead of simply covering the body to avoid the cold, what is needed is the maintenance and comfort of the human body. Therefore, natural fibers have become the first choice because of their ability to absorb moisture and wick away moisture for next-to-body skin care. For this reason, chemical fiber yarns have also worked hard in this area. People have developed methods that can increase moisture absorption. For porous moisture absorption, there are dissolution methods, foaming methods, phase separation methods, and grafting modification methods. Surface treatment ...
