Embodiment 1

[0030] A high imitation cotton fiber for sportswear and a preparation method thereof, the specific process of preparing the high imitation cotton fiber is as follows:

[0031] Add 17kg of hydroxymethylcellulose into a reaction vessel equipped with 1000L of distilled water and equipped with a stirrer, and stir magnetically at 55°C until it is completely dissolved. Then add 150L acrylic acid and 0.85kgN, N ， - Methylenebisacrylamide, stirred until the solids are completely dissolved. Then add 0.85kg of ammonium persulfate, after stirring slowly at a speed of 55r / min, cover the reaction vessel with a film, and place it in a constant temperature water bath at 80°C, and obtain a cellulose hydrogel after reacting for 6 hours; pull the polyurethane fiber Put it upright and vertically in the working room of the multi-pulse laser drilling instrument, set the working current to 25A, the repetition frequency to 4.5kHz, and the relative moving speed to 7mm / s. After alignment, turn on the...

[0034] A high imitation cotton fiber for sportswear and a preparation method thereof, the specific process of preparing the high imitation cotton fiber is as follows:

[0035] Add 18 kg of hydroxymethylcellulose into a reaction vessel with 1000 L of distilled water and a stirrer, and stir magnetically at 60° C. until it is completely dissolved. Then add 160L acrylic acid and 0.85kgN, N ， - Methylenebisacrylamide, stirred until the solids are completely dissolved. Then add 0.85kg of ammonium persulfate, stir slowly at a speed of 40r / min, cover the reaction vessel with a film, and place it in a constant temperature water bath at 78°C, react for 7 hours to obtain cellulose hydrogel; pull the polyurethane fiber Place it vertically and vertically in the working room of the multi-pulse laser drilling instrument, set the working current to 3A, the repetition frequency to 3kHz, and the relative moving speed to 8mm / s. The surface is etched to form micropores with a certain taper. Th...

Abstract

The invention belongs to the technical field of preparation of composite fibers and provides highly-cotton-like fibers for sportswear and a preparation method. The preparation method comprises the following steps: cellulose gel is prepared from cellulose for standby application, nano micropores are formed in surfaces of polyurethane fibers by laser ablation, then the polyurethane fibers with the micropores are soaked in the pre-made cellulose gel, the cellulose gel is deposited on the surfaces of the polyurethane fibers and in the micropores, a coagulating bath is adopted for coagulating, drying is performed, and the highly-cotton-like fibers for sportswear are obtained. Compared with the traditional methods, the prepared composite fibers have the advantages of good cotton comfort, light weight as well as good breathability, waterproofing, wet conductivity and the like, and the preparation process is simple, convenient to operate, energy-saving and environmentally friendly and has goodgeneralizability.

Description

technical field [0001] The invention belongs to the technical field of composite fiber preparation and provides a high imitation cotton fiber used in sportswear and a preparation method. Background technique [0002] In recent years, due to people's continuous pursuit of health, sports have become fashionable, and the market for sportswear is also growing. With the development and progress of science and technology, people have higher and higher requirements for sportswear, and new sportswear with high-tech content and comprehensive functions has become an inevitable trend of development. Sportswear is not only required to be "light, thin, soft and warm", but also required to be infused with waterproof, breathable and other requirements. When worn, it is required to have good sports comfort function, each part of the human body is free to expand and contract, and has good extensibility and elasticity. Good protective effect; fabrics are required to have good moisture-wickin...
