Problems solved by technology

Some people try to finish nylon fabric with hydrophilic polyester for finishing polyester, but the effect is not satisfactory
The literature "Research on Synthesis and Application of New Polyamide Fiber Hydrophilic Finishing Agent PPAG" (2012? Printing and Dyeing Auxiliaries? Magazine Volume 29 Issue 6) reported the use of polyethylene glycol, succinic anhydride, adipic acid, adipic acid, A technical scheme for synthesizing a hydrophilic finishing agent for nylon fabric with diamine. The nylon fabric treated with this finishing agent has certain moisture absorption and quick-drying effects, but the dry and wet rubbing fastness and hand feeling of the fabric after finishing are not ideal.

Abstract

The invention relates to a moisture-absorption and sweat-releasing finishing agent for chinlon, and a preparation method thereof. The finishing agent is non-ionic type polyetheramide copolymer, and the aqueous solution is yellow to deep yellow liquid. The finishing agent has a polyether chain section, so that the finished chinlon textile has excellent moisture absorption and fast drying properties; the molecular structure of the finishing agent comprises an amide chain section formed by adipic acid and hexanediamine, by utilizing the structure similarity principle, the amide chain section in the molecular structure of the finishing agent and the fiber molecular chain of chinlon form co-crystallizing under the high-temperature baking condition and are inlaid on the surface of the fabric, so that the finished chinlon fabric has durable moisture absorption and fast drying properties; the reactive functional group in molecules of the finishing agent can generate crosslinking film forming action in the baking and finishing processes, the moisture absorption and fast drying durability and dry-wet friction fastness of the finished fabric can be further enhanced on the basis of co-crystallizing action. In addition, the hand feeling of the fabric can be favorably improved by the organosilicon chain section in the molecular structure of the finishing agent and the methyl in the polyether chain section.

Description

Technical field [0001] The invention relates to a functional textile finishing agent technology, in particular to a moisture wicking finishing agent for nylon and a synthesis method thereof. Background technique [0002] Polyamide fiber fabrics have soft texture, wear resistance, good dyeability, light specific gravity and good elasticity. They have always occupied an important position in the clothing industry. They are mainly used to make underwear, sports jackets, and various hosiery. As people have higher and higher requirements for the comfort, health, safety, and environmental protection of clothing fabrics, the trend of mutual penetration and integration of casual wear and sportswear has also become increasingly popular among consumers. Fabrics require not only good comfort, but also during activities, once consumers are sweating, the clothing will not stick to the skin and cause discomfort. Therefore, new requirements for moisture absorption and perspiration function are ...
