Cationic ultra-fine and high-density fibers capable of being dyed at room temperature

Abstract

The invention discloses cationic ultra-fine and high-density fibers capable of being dyed at room temperature. A special combination of raw materials is used to produce the cationic ultra-fine and high-density fibers capable of being dyed at room temperature, the produced fibers have luminous properties, and the problems that cationic fibers capable of being dyed at room temperature is difficult in dyeing and poor in fixation rate are avoided; the cationic ultra-fine and high-density fibers capable of being dyed at room temperature is easy to dye, luminous and good in stability and also has the softness of ultra-fine fibers; a special preparation process which is not a simple technical superposition is adopted, the side reaction problem after adding luminous raw materials into conventionalcationic fibers capable of being dyed at the room temperature is effectively solved, and luminous property lowering can be avoided while the dyeing rate and fixation rate can be ensured.

Description

technical field [0001] The invention belongs to the technical field of chemical fibers, and in particular relates to a cationic normal-temperature dyeable superfine high-density fiber. Background technique [0002] Due to the numerous excellent properties of polyester (polyester) fibers, it has developed rapidly all over the world. However, polyester molecular chains are closely gathered, and its dyeing performance is poor, and there are few types of dyes that can be used. Generally, polyester fibers can only be dyed with disperse dyes at high temperature or in the presence of carriers. Cationic dyes can dye modified polyester fiber, which has become the largest modified polyester variety. However, polyester macromolecules lack functional groups that can combine with direct dyes, acid dyes, basic dyes, etc. Although ester groups that can form hydrogen bonds with disperse dyes, polyester has high crystallinity, and dye molecules are not easy to enter the fiber. Difficulty, ...

Problems solved by technology

Due to the small diameter of microfiber, its bending stiffness is very small, the fiber feels very soft, has strong cleaning function and waterproof and breathable effect, microfiber has many tiny pores between microfibers, forming capillary structure, processing If it is made into towel fabric, it has high water absorption; but it is not easy to dye in the subsequent processing process, and the color fixing effect is poor

[0004] With the progress of society and the continuous improvement of living standards, people have higher and higher requirements for fabrics. Usually, fabrics woven from cationic room temperature dyeable fibers are used for sports and leisure fabrics, but the softness is poor, and dyeing is difficult. With luminous function, the safety is poor when used at night

At present, the common way to make luminous fabrics in the market is to weave optical fibers and silk threads together through textile machines through textile technology. The disadvantage of this is that the textile thread materials are relatively limited, the luminous effect of the product is not good, and the weaving cost is high. Realize mass production; or coat a layer of luminous film on the fabric, which is only a simple technical superposition, and the luminous film is easily damaged

[0005] If luminescent materials are added to the raw materials of ordinary cationic room temperature dyeable fibers to realize the luminescent function of fibers, it will result in difficulty in dyeing cationic room temperature dyeable fibers, poor color fixation rate, and at the same time, the luminous performance is also affected. Therefore, the invention A cationic room temperature dyeable fiber that is easy to dye, can emit light, has good stability, and has the softness of superfine fibers is the technical problem to be solved by the present invention
