Problems solved by technology

However, the shape retention and stretchability of natural fibers are poor, and many things such as vigorous twisting and exposure to the sun should be avoided during washing. For underwear, natural fibers seem to be powerless and need to be improved.

preparation example Construction

[0042] The preparation method of antistatic bamboo charcoal fiber for underwear, comprising,

[0043] The carbonization process of carrying out high-temperature carbonization treatment on moso bamboo; the homogenization process of bamboo charcoal obtained by carbonization; the spinning stock solution preparation process; and, the spinning process;

[0044] The dry strength at break of the bamboo charcoal fiber obtained in the above spinning process can reach 2.0-4.5 cN / dtex, and the wet strength at break can reach 1.8-3.8 cN / dtex. In this method, the bamboo charcoal is subjected to ultrafine treatment to form a micropowder to the nanometer level, and then the nanoscale bamboo charcoal is added to the stock solution formed by cellulose, and the fiber is prepared by the textile process, which retains the adsorption, deodorization, and Moisture absorption and perspiration, heat storage and warmth, antibacterial and anti-mildew and good far-infrared and negative ion emission, anti...

Embodiment 1

[0069] The preparation of one of the products of polymer A is specifically realized through the following steps:

[0070] 1) Take adipic acid and place it in 2-3 times the amount of thionyl chloride solution, heat it in a water bath to 30-50° C., remove the solvent, and place the obtained precipitate in a three-component solution containing 2-10% by weight In the acetonitrile solution of ethylamine and 1-15% 4-dimethylaminopyridine, then dropwise add phenylenediamine thereinto, and stir slowly, after the reaction is complete, wash with dilute hydrochloric acid, after removing the solvent, namely the above Chinese formula Blocks of (IIb);

[0071] 2) Add serine and Boc anhydride to tetrahydrofuran solution containing potassium hydroxide, overnight at 0-4°C, then add the above-mentioned block to it, and add 5-8 times the amount of polyphosphoric acid solution, and then place on ice in the bath for 30-60 minutes, then raise the temperature to 80-95°C and react for 1-3 hours to o...

Embodiment 2

[0081] The preparation method of antistatic bamboo charcoal fiber for underwear, its concrete steps are as follows:

[0082] 1) Choose moso bamboo more than 5 years old, keep the temperature at 160°C and dry for 6 days, then raise the temperature to 360°C for pre-carbonization for 4 days, then raise the temperature to 880°C for 5 days, cool to obtain block bamboo charcoal;

[0083] 2) Place the block bamboo charcoal in the suspension containing the photocatalyst of 0.35% by weight, and then use a dose of 30Gy 60 Co-gamma ray irradiation for 45s, after completion, take out and dry, and the photocatalyst suspension also contains 0.06% glycine and 0.08% benzenesulfonic acid by weight;

[0084] 3) First crush the block bamboo charcoal to a particle size of 10mm or below and then carry out jet milling. After the jet milling, classify, collect the particles with a particle size of less than 300nm for later use, and return the particles with a particle size greater than 300nm for jet...

Abstract

The invention provides an antistatic bamboo charcoal fiber for underwear, and belongs to the field of textiles. A preparation method of the fiber includes a carbonization process for high temperaturecarbonization of moso bamboos, a homogenization process for bamboo charcoal obtained after carbonization, a preparation process of a spinning solution, and a spinning process. The bamboo charcoal fiber obtained by the spinning process has dry tensile strength of 2.0-4.5 cN / dtex and wet tensile strength of 1.8-3.8 cN / dtex. The bamboo charcoal fiber can prevent surface charge accumulation, and has enhanced antistatic effect and antistatic endurance, excellent shaping durability and shape retention, reinforced heat and washing resistance, and improved wearing comfort; the preparation method can improve the tensile strength of the fiber, especially the wet tensile strength, breakage and blockage can be prevented during spinning, damage to the fabric due to exposure to the blazing sun can be alleviated, and the fiber can be resistant to scrubbing and twisting and does not deform, so that the spinnability of the fiber and the quality of fiber products are improved.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to antistatic bamboo charcoal fibers for underwear. Background technique [0002] Underwear is known as "the second skin of the human body". It is the only clothing that people never leave in their lives. It has the functions of protecting, decorating and correcting the human body. In the 21st century, as people's awareness of health and environmental protection has increased, consumers have paid considerable attention to whether underwear is "green", "ecological", and whether it is safe to wear. Because the underwear is close to the human skin, the choice of fabric is particularly important, especially for sensitive skin or skin with diseases. If the underwear fabric is not selected properly, it may cause harm to the human body. At the same time, the sweat and dander of the underwear are multiplied for nutrition, which poses a threat to human health and even induces various diseases. Ther...
