Problems solved by technology

As one of the four major synthetic fibers, nylon 6 fiber is widely used in textiles, clothing and other non-fabric fields because of its excellent physical and chemical properties. Most fabrics will pursue moisture absorption, breathability and high smoothness, while the current common The moisture absorption and air permeability of nylon fiber is difficult to meet the increasing demand of consumers, and the nylon fiber is prone to hairy phenomenon due to the water content and oiling of raw materials, which affects the touch and appearance, and has a certain impact on the quality of the fabric.

Abstract

The invention discloses a preparation process of a smooth and high moisture-absorbing polyamide fiber. Starting from a raw material, a modified activated carbon fiber is used as a carrier, and modified master batch with excellent moisture permeability and functions and a weak magnetic property can be prepared; meanwhile, moisture in polyamide fiber six slices can be absorbed, so that the water content and the influence in the fiber spinning process can be reduced, the spinning quality is improved and a filament breaking phenomenon is not easy to occur; in addition, an oiling system is innovatively introduced with a dynamic oil feeding assembly, and oil is actively absorbed for oiling based on the adsorption effect on magnetic oil by the weak magnetic property of the fibers, so that oilingis quite uniform, direct physical contact is avoided, and broken filaments generated by friction can be avoided; and meanwhile, the absorbed oil amount is relatively stable due to the magnetic property, the oiling effect is stable and falling off does not occur easily, waste of oil is reduced, the oiling cost is lowered, and moisture absorption and smoothness of the polyamide fiber are comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of chemical fiber preparation, in particular to a preparation process of smooth and highly hygroscopic nylon fiber. Background technique [0002] Nylon is polyamide fiber, which is called nylon (nylon) abroad. It is the first industrialized fiber in the world. It began industrial production in 1938. Nylon fiber is widely used in apparel textiles and industrial textiles because of its high strength and excellent wear resistance. The excellent apparel properties of nylon fiber have been widely recognized by consumers. Nylon fiber has high strength and high elasticity. Good dyeing performance and other characteristics. [0003] With the improvement of living standards and the increase of leisure time, people put forward higher requirements for the quality of clothing fabrics. Fashionable, healthy, comfortable and casual clothing is more and more popular among consumers, and clothing fabrics are becoming more a...
