A processing method of hemp ash wrapped yarn with intermediate color characteristics and hemp ash wrapped yarn

Abstract

The invention provides a processing method of a heather grey wrapped yarn with secondary color feature and the heather grey wrapped yarn. According to the processing method, by utilizing a color mixing / section color effect principle of combining and twisting two yarns with different colors, a specific core yarn false twist effect when the core yarn is wound with a hollow ingot outer wrapped yarn and an instable twist degree principle, a black yarn and a white yarn form a double-core yarn by virtue of a hollow ingot wrapped spinning technique, a low-twisting ''black-white secondary color'' effect is formed through a false twist effect caused by the tension force of the outer wrapped yarn to the core yarn, the black yarn or the white yarn is taken as the outer wrapped yarn for wrapping so asto obtain the heather grey wrapped yarn with a ''black-grey'' secondary color feature or a ''white-grey'' secondary color feature or an irregular and random secondary color effect. A heather grey fabric can be endowed with a specific and irregular section color effect, and compared with uniformly distributed heather grey fabrics, the heather grey wrapped yarn has a relatively vivid and vivaciousstyle. The produced heather grey wrapped yarn does not need to be colorized during the spinning, a produced fabric does not need to be dyed, and a finished shell fabric can be obtained only through necessary finishing and processing processes of washing, shaping and the like.

Description

technical field [0001] The invention belongs to the processing technology of pattern-color composite yarn, and in particular relates to a processing method of hemp ash wrapped yarn with intermediate color characteristics and hemp ash wrapped yarn. Background technique [0002] Hollow spindle wrap spinning is a technology that specializes in the production of composite structure yarns. Its technical feature is that one yarn (filament yarn or spun yarn) is helically wound to another yarn (filament yarn or spun yarn) to form a composite yarn with a wrapped structure (twisted twist). [0003] The core of hollow spindle wrapping spinning technology is hollow spindle wrapping technology, which is also applied in parallel spinning technology (machine) and hollow spindle fancy twisting technology (machine), the former is used for spinning short fiber wrapping Yarn (the core yarn is the staple fiber after drafting), the latter is specially used for spinning fancy yarn (the core yarn...

AI Technical Summary

Problems solved by technology

In a broad sense, hemp gray can actually be considered as the visual effect of the fabric. Blended hemp gray yarn can be used to give the fabric the appearance of hemp gray, and black yarn and white yarn can be used for cross-twisted yarn, double-twisted yarn, or even black yarn. Interweaving with white yarn can also give the fabric the appearance of hemp gray, but these technologies use yarn as the color carrier for color mixing, the visual effect of the fabric will be different from that of blended hemp yarn, and the style is more rough, not as good as Fine fiber grade color mixing
