Spinning method of air conditioner fiber and cotton fiber/viscose fiber blended yarn

Abstract

The invention discloses a blended yarn of an air-conditioning fiber and a cotton fiber / a cotton-type chemical fiber. The blended yarn is composed of, by mass, 30-60% of the air-conditioning fiber, and 40-70% of the cotton fiber / the cotton-type chemical fiber. The invention further discloses a preparation method of the blended yarn. The method comprises the steps that the opening and picking process and carding process are conducted on the weighed air-conditioning fiber and the weighed cotton fiber / the cotton-type chemical fiber, then carding sliver of the air-conditioning fiber is obtained and carding silver of the cotton fiber / the cotton-type chemical fiber is obtained; a drawing frame is used for conducting drawing on all the carding silver, then drawn silver of the air-conditioning fiber is obtained, and drawn silver of the cotton fiber / the cotton-type chemical fiber is obtained; the drawn silver of the air-conditioning fiber and the drawn silver of the cotton fiber / the cotton-type chemical fiber are mixed to obtain a strip-shaped air-conditioning fiber and cotton fiber mixture or an air-conditioning fiber and cotton-type chemical fiber mixture; a coarse spinner and a spinning frame are used for processing the mixture to obtain the blended yarn. The blended yarn not only has the good temperature regulation effect, but also has a good mechanical property and yarn evenness.

Description

technical field [0001] The invention belongs to the technical field of functional textile yarn preparation, and relates to a blended yarn of air-conditioning fiber and cotton fiber / cotton chemical fiber, and also relates to a spinning method of the blended yarn. Background technique [0002] At present, most of the textiles prepared from air-conditioning fibers are blended products. However, there is no exact research to indicate the appropriate blending ratio and how the air-conditioning fiber is distributed in the cross-section of the blended yarn, which is most conducive to its temperature regulation function. [0003] A high air-conditioning fiber content will cause a substantial increase in yarn cost, while a low air-conditioning fiber content will not be able to play its temperature-regulating function. At the same time, the distribution of air-conditioning fibers in the yarn cross-section is different, which will cause damage to the air-conditioning fiber microcapsul...

Problems solved by technology

However, there is no exact research to indicate the appropriate blending ratio and how the air-conditioning fibers are distributed in the cross-section of the blended yarn that is most conducive to its temperature regulation function.

[0003] A high air-conditioning fiber content will cause a substantial increase in yarn cost, while a low air-conditioning fiber content will not be able to play its temperature-regulating function

At the same time, the distribution of air-conditioning fibers in the yarn cross-section is different, which will cause damage to the air-conditioning fiber microcapsules in the post-processing of textile dyeing and finishing, and affect the temperature adjustment effect.
