Raw color matching yarn and preparation technology thereof

Abstract

The invention relates to a raw color matching yarn and a preparation technology thereof. The raw color matching yarn is characterized in that one beam of composite yarn which is formed by melt-spinning contains two or more types of raw color fiber with different colors; each raw color fiber is a single yarn in a single color. The preparation technology comprises the following steps of metering melts of different colors by different metering pumps, enabling the melts to enter distribution plates through different melt flow passages, and enabling the distribution plates to distribute the melts into different yarn spraying holes. The raw color matching yarn has the advantages that multiple types of raw color yarns of which the colors are difficult to distinguish by naked eyes are prepared into the composite yarn by melt-spinning, so as to obtain the single-color fiber with a uniform macrostructure, the appearance of strip dyeing or piece dyeing type single-color fiber is realized, and theexistence of multiple colors in the fiber cannot be distinguished under the near-distance observation condition; the layering feel is fine, and the vision style is particular.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to an original color-matching silk and a preparation process thereof. Background technique [0002] In recent years, the development of high-tech chemical fiber products in the world has been extremely rapid, and the modification, development and research of synthetic fibers have also entered a new stage. Synthetic fibers are generally developing in the direction of fine denier, high performance, and multi-function. Most of the chemical fiber enterprises with advanced technology in the world use methods of changing the shape and appearance of fibers and their special-shaped cross-sections to develop synthetic fibers in spinning engineering. Fiber new products, to create a variety of new synthetic fibers and high-grade fabrics with their own characteristics. [0003] In the prior art, the blending of filaments is mainly concentrated on DTY processing. Usually, different deniers and di...

Problems solved by technology

At present, melt direct spinning color spinning is still difficult to meet the requirements of multi-color and multi-variety. Currently, color spinning is still dominated by chip spinning. Although chip spinning can meet the needs of variety replacement to a certain extent, the transition required in the replacement of varieties There are more materials or cleaning materials, which seriously affects the cost. The cost of chip spinning is 10-20% higher than that of melt direct spinning, which limits the increase in color spinning output.
