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...
