preparation example Construction

[0023] The preparation method of the cotton fiber and hemp fiber blended core-spun yarn of the present invention comprises the following steps: cleaning → carding → drawing → roving → spun yarn.

[0024] In the present invention, the cleaning process adopts two porcupine openers, one adopts a porcupine beater, and the other adopts a comb needle beater; the rotating speed of the porcupine beater is 560r / min, and the speed of the comb needle beater is 500r / min. min, the speed of the head beater is 980r / min, the fan speed is 1250r / min, the basis weight of the lap is 435g / m, and the uniformity of the lap is 1.0%.

[0025] Because the hemp fiber has poor length uniformity, high rigidity, brittleness, hardness and easy fracture, and poor cohesion, so hemp and cotton are mixed in multiple warehouses to improve the preventability.

[0026] In the present invention, in the carding workers, the sequential sliver weight is 24g / 5m, the cylinder speed is 340r / min, the doffer speed is 22r / m...

Abstract

The invention aims to disclose a cotton fiber and hemp fiber blended covering yarn and a preparation method thereof. The covering yarn cotton fiber and hemp fiber are blended into the cotton fiber and hemp fiber blended covering yarn in a jet vortex spinning, the weight percentage of the cotton fiber is 30-50%, and the weight percentage of the hemp fiber is 50-70%. Compared with the prior art, the cotton fiber and hemp fiber blended covering yarn has the advantages of antibiosis, anti-mite, thermostability, nature and roughness, softness and comfortableness, and moisture absorption and sweat releasing, hemp cotton blended yarn is blended into the covering yarn as a yarn core, and accordingly problems of touch roughness and stiffness of fibrilia and low chromaticity are avoided, and the cotton fiber and hemp fiber blended covering yarn is achieved.

Description

technical field [0001] The invention relates to a core-spun yarn and a preparation method thereof, in particular to a cotton fiber and hemp fiber blended core-spun yarn and a preparation method thereof. Background technique [0002] In the 21st century, where the pace of life is getting faster and faster, people pay more attention to the quality of life, and health preservation has become an important topic in people's lives. From the perspective of market consumption trends, people's pursuit of bedding functions has shifted from warm-keeping to health-care, especially for natural fibers with functional features. [0003] Hemp fiber has excellent moisture absorption and perspiration performance, natural antibacterial health care performance, good soft and comfortable performance, excellent anti-ultraviolet performance, excellent high temperature resistance performance, unique wave absorption performance and natural rough style, known as " The King of Hemp". However, compar...
