Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, and in particular to an antistatic quick-drying nylon multi-layer composite fabric and a preparation method thereof. Background Art

[0002] With the development of the times, people have higher and higher requirements for fabrics, and developing fabrics that can meet consumer needs plays an increasingly important role in fabric production. Waterproof and breathable functional clothing can block the damage of bad weather and prevent rain and snow from penetrating, while also timely expelling sweat and moisture generated by exercise, thereby regulating the human microenvironment and providing good comfort for the human body, so that the protective function and comfort of clothing fabrics are unified;

[0003] The existing single-layer textile fabrics can no longer meet people's daily needs, especially in terms of anti-static and quick-drying performance. Single-layer fabrics cannot effectively resist static electricity. In addition, because fabrics are prone to breed a large number of bacteria or microorganisms after long-term use, it will affect its practicality and safety. Therefore, multi-layer composite fabrics have gradually received widespread attention.

[0004] Although traditional nylon fabrics have certain wear resistance and elasticity, they perform poorly in terms of anti-static and quick-drying properties. The generation of static electricity not only causes discomfort in wearing, but may also cause safety hazards such as spark discharge. At the same time, traditional nylon fabrics also have defects in moisture absorption and perspiration, making it difficult to meet the needs of quick drying.

[0005] In the prior art, the PA56 short fibers used in large quantities have a large specific resistance and serious electrostatic phenomena. Static charges often accumulate on the fiber surface and are not easy to dissipate. The electrostatic phenomenon in the fiber processing process will cause problems such as difficulty in the combing process, unclear yarn separation, and accumulation of flying flowers and dust. The patent with publication number CN114737271A mixes PA56 with graphene to produce graphene nylon fiber to improve the antistatic durability of graphene nylon fiber. However, the breaking strength of nylon filaments and yarns treated with graphene is significantly reduced, and the use value will also be greatly affected.

[0006] Therefore, the antistatic quick-drying nylon multi-layer composite fabric and related technologies still need to be further improved. Summary of the invention

[0007] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide an antistatic quick-drying nylon multi-layer composite fabric and a preparation method thereof, which solves the problems of poor antistatic performance and low mechanical strength of nylon fabrics in the prior art.

[0017] On the basis of this technical solution, it is further preferred that the surfactant is cetylpyridinium chloride, and the molar ratio of the surfactant to graphene is 2.5-5%.

[0018] On the basis of this technical solution, further preferably, the molar ratio of the graphene to the polypropylene is 0.03-0.05:1.

[0019] On the basis of this technical solution, further preferably, the preparation method of the moisture absorbent comprises the following steps:

[0020] Weigh 80-100 parts of silicone oil, 12-20 parts of epoxy-terminated allyl polyether, 45-60 parts of DMF, and 18-24 parts of n-dodecene, add them into the reaction, mix and stir, and heat to 75-80°C;

[0021] Then add 0.8-1.6 parts of chloroplatinic acid, keep the temperature to react for 1-2 hours, cool down, distill, add 30-42 parts of emulsifier, mix well, add acid to adjust the pH to 7, and obtain a hygroscopic agent.
