[0020] In order to solve flax / viscose fiber blending in the prior art, flax fiber and viscose fiber are mostly blended directly. , leading to poor spinnability of flax fiber, directly blended with viscose fiber, the prepared blended yarn has serious hairiness, which affects the quality of the blended yarn. The invention provides a kind of preparation method of modified flax / viscose fiber blended yarn, comprising the following steps:

[0021] Flax fiber pretreatment, put the flax fiber in water, soak in ultraviolet light for 20-30min, take it out and dry;

[0022] Flax fiber modification, adding the pretreated flax fiber to the maleic anhydride solution, nitrogen protection, ultrasonic treatment for 35-55 minutes, taking it out and washing it until neutral, then immersing it in the silk protein polypeptide solution to adjust the pH and temperature of the solution , and then drop the ethanol solution of DCC into the solution, react under ultraviolet light for 1-1.5h, take out t...

Abstract

The invention discloses a modified flax / viscose fiber blended yarn and a preparation method thereof. Firstly, hydroxyl in flax fiber reacts with maleic anhydride to generate flax cellulose maleic acidmonoester, and carboxyl is introduced into the flax fiber to improve the crystallinity of the flax fiber at the same time; and then the carboxyl in the flax fiber and free amino groups of polypeptideof silk protein form an amido bond and the polypeptide is grafted on the flax fiber to change the spinnability of the flax fiber and to reduce the hairiness.

Description

technical field [0001] The invention relates to the technical field of flax / viscose fiber blending, in particular to a modified flax / viscose fiber blended yarn and a preparation method thereof. Background technique [0002] In recent years, with the development of society and the advancement of science and technology, people's pursuit of healthy life and quality life has gradually increased, and functionality and ecology have become the factors that consumers pay attention to when choosing textiles. Viscose is a regenerated cellulose fiber that can be naturally degraded, which is very in line with the current concept of green environmental protection; viscose staple fiber can be purely spun or blended, and is suitable for the production of underwear, outerwear and various decorative products. Flax fiber is the earliest natural fiber used by humans. Because of its natural spindle-shaped structure and unique pectin beveled holes, it has good hygroscopicity and can absorb water...
