Embodiment Construction

[0006] The present invention will be further described below in combination with practical examples.

[0007] Example: spinning 8 degrees 32 hemp gray yarn, the fiber content of cotton yarn is 30%, of which black chemical fiber is 8%, white chemical fiber is 22%, and pure cotton is 70%. When rolling, the blending ratio of white chemical fiber and black chemical fiber is: white chemical fiber = 22 / 8 black chemical fiber = 2.75 black chemical fiber, that is to say, 1 ton of black chemical fiber is mixed with 2.75 tons of white chemical fiber. According to production needs, or choose 100 kg of black chemical fiber and 275 kg of white chemical fiber, the specific method is to divide 100 kg of black chemical fiber and 275 kg of white chemical fiber into 5 equal parts, first spread 55 kg of white chemical fiber evenly on the clean cement floor, It is required to be shredded, and the thickness of the book is consistent, and then 20 kg of black chemical fiber is shredded and evenly sp...

Abstract

The invention relates to the production field of grey flax yarns, in particular to a method for preparing the grey flax yarn. Before fed onto a slot, a natural color chemical fiber and a black chemical fiber are mixed section by section according to a proportion; by adoption of manual tearing and stirring, a cotton block becomes thinner; and the thinner cotton block is fed to the slot and rolled finally. By adoption of the technical scheme, the process is simple, the cotton roll has uniform mixed color, and the quality is stable.

Description

technical field [0001] The invention relates to the production field of hemp ash yarn, and relates to a preparation method of hemp ash yarn. Background technique [0002] Hemp gray yarn series varieties are widely used in the production of knitted garment fabrics and underwear products. The key technology is that different colors and heterosexual fibers are mixed evenly, and the quality of cotton yarn does not appear color difference. When the colored fiber content in the cotton yarn is 2%-15%, in order to fully mix with the cotton fiber in the subsequent process, it is necessary to add an appropriate amount of natural polyester fiber to dilute it. In order to ensure the effective and uniform mixing of the two chemical fibers, there are two traditional processing methods: Method 1 The natural color polyester fiber and the black polyester fiber are put on the sliver separately, and rolled separately, and then mixed on the drawing frame after carding. The problem with this met...
