Problems solved by technology

[0005] Although modified or modified nylon fibers have achieved better functionality in one aspect, other technical problems will inevitably occur. For example, nylon functional fibers prepared by similar blending methods have a large amount of other components inside the fibers , the internal stress of each segment of the macromolecule is uneven, with an unstable structure, which makes the shape stability of the fiber poor, the shrinkage rate in boiling water is as high as 20-25%, the quality control is very unstable, the effect of taking it is poor and it is particularly easy to cause The dyeing performance is not good, and it is easy to cause the decline of the dyeing performance, which is manifested in the decline of the dyeing rate and the increase of the unevenness of the dyeing.
[0006] And because the amorphous area of ​​nylon fiber is relatively small, and the moisture absorption and moisture regain are about 4.5%, so in the process of use, its wearing comfort, electrostatic influence, dyeing effect, etc. are far inferior to cotton and viscose fibers, etc. cause a certain impact

Abstract

The invention discloses an easy-dyeing modified polyamide fiber. The easy-dyeing modified polyamide fiber contains 1-5% of naringin; the preparation method of the easy-dyeing modified polyamide fibercomprises the following steps of preparing a naringin-containing functional composition, preparing a modified functional composition, preparing naringin-containing functional master batch, and spinning. The coloring modifier is preferably added in the preparation of the naringin-containing functional composition, the dyeing performance of the prepared fiber can be greatly improved by adding the coloring modifier, the dyeing grade is greater than or equal to 5 grade, the dyeing rate is greater than or equal to 86%, the dyeing rate of the fiber is remarkably improved, and the dyeing unevenness of the fiber is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of chemical fibers, in particular to an easy-to-dye modified nylon fiber. Background technique [0002] Nylon, the scientific name of polyamide fiber, is the general name of nylon fibers produced in China. Internationally known as nylon, it has high strength, wear resistance, and good resilience. It can be purely spun or blended for various clothing and knitwear. The main varieties are nylon 6 and nylon 66, and their physical properties are similar. Nylon has better hygroscopicity and dyeability than polyester, and is resistant to alkali but not acid. Its fiber strength will decrease if it is exposed to sunlight for a long time. Nylon has heat setting properties and can maintain the bending deformation formed when heated. Nylon filaments can be made into elastic yarns, and short yarns can be blended with cotton and acrylic to improve its strength and elasticity. In addition to the application in clothing ...
