Problems solved by technology
However, the chenille products currently on the market are basically traditional viscose / nitrile, cotton / polyester, viscose / cotton, nitrile / polyester, viscose / polyester, etc., which are 824N / 1 (24 strands per strand) spun by a fancy twister. Chenille products, there is no chenille product containing wool, and the chenille products produced at the present stage on the market are all white blank yarns, which are dyed after being spun into chenille yarns. This process seriously restricts the production of chenille. Development and technological innovation, because the shrinkage rate of strand dyeing chenille is unstable, and the cabinet dyeing vat is prone to rod marks (dots that cannot be dyed on the strand dyeing), the hand feels dry after dyeing, and the color is single, resulting in products that have always been in the dark. The middle and lower reaches of the market
At the same time, due to the rising prices of energy and raw materials in the market, the competition in the international market is fierce, and at the same time, domestic products that can compete with it cannot be spun
Forced to use viscose, polyester and other diversified chemical fibers to spin chenille single yarn, resulting in a decline in the quality of the product, resulting in serious degradation of the domestic fabric market and products
Domestic color spinning chenille relies on imports (mainly from Germany), which leads to an increase in the cost of color spinning chenille products. At present, there is no wool concept product for color spinning.

The invention discloses processing technology for color spinning colorful chenille yarn. A special process method is adopted on the procedures of dyeing, spinning and chiffon spinning and the like, chenille products containing wool can be spun, and the technical problem of hank dyeing is solved. The processing technology has the advantages that acrylic dyeing spinning chenille products containing the wool well fill up the gap of the hank dyeing, the processing technology ensures that color and yarn levelness of the chenille yarn are even. Therefore, the multi-color color spinning colorful chenille yarn developed on the basis of the processing technology expands the new field of the chenille yarn.
Description
(1) Technical field [0001] The invention relates to a processing technology of fabric yarn in the textile field, in particular to a processing technology of colored chenille yarn for color spinning. (2) Background technology [0002] In order to obtain better appearance and softness, chenille yarn has become one of the choices of fabric designers. Through the application of chenille yarn, the appearance, hand, softness and luster of many products have been improved, these products include sweaters, outerwear fabrics, upholstery fabrics and blankets. However, the chenille products currently on the market are basically traditional viscose / nitrile, cotton / polyester, viscose / cotton, nitrile / polyester, viscose / polyester, etc., which are 824N / 1 (24 strands per strand) spun by a fancy twister. Chenille products, there is no chenille product containing wool, and the chenille products produced at the present stage on the market are all white blank yarns, which are dyed after being s...
