Abstract

The invention relates to a hygroscopic synthetic fiber and a preparation method thereof, and belongs to the technical field of functional synthetic fibers. The hygroscopic synthetic fiber is prepared from, by weight, 40-46 parts of polyurethane, 50-58 parts of polystyrene, 55-65 parts of polyvinylpyrrolidone, 3-7 parts of modifying agents, 1-5 parts of softening agents, 3-7 parts of nonionic surfactants and 80-88 parts of acetone. The preparation method comprises the steps that the solid raw materials are processed through ball milling for 20-26 min and then preheated for 20-28 min at the temperature of 80 DEG C-90 DEG C, the other components are added, ultrasonic processing is performed for 30-38 min, and mixing granulating is performed in a mixing mill; melt spinning is performed on master batches obtained through mixing granulating at the temperature of 390 DEG C-430 DEG C under the pressure of (3-7)*10<5>Pa to obtain the finished product. The synthetic fiber has the long-time hygroscopic energy consumption and is comfortable and smooth in handfeel, capable of being applied to close-fitting garments such as underwear and sport shirts, low in production cost, simple and controllable in technology and suitable for industrialized production.

Description

technical field [0001] The invention relates to a hygroscopic synthetic fiber and a preparation method thereof, belonging to the technical field of functional synthetic fibers. Background technique [0002] The petrochemical industry is an important part of the chemical industry, plays an important role in the development of the national economy, and is one of the pillar industries of our country. Petrochemical refers to the processing industry that uses oil and natural gas as raw materials to produce petroleum products and petrochemical products. [0003] Petrochemical products are closely related to people's lives, ranging from spacecraft in space, airplanes in the sky, ships on the sea, trains on land, and automobiles to our daily computers, desks, toothbrushes, towels, food packaging containers, Colorful clothing, all kinds of building materials and decoration items, and varied amusement equipment, etc., are all closely related to petrochemical industry. It can be said...
