Description
Technical field
The invention belongs to yarn manufacturing technology field, be specifically related to the manufacture method of the two component blended yarn of a kind of colored fibre.
Background technology
The color of textiles is also along with the raising of consumers living and the level of consumption becomes more and more diversified.For the demand that textile enterprise's reply is personalized, the production requirement of its product is " small lot, multi items ".The product batch of some spinning enterprise is little of tens kilograms even several kilograms, and multi items aspect, the change of color is ever-changing.CNS colour system-CNCS colour system that China Textile Information Center sets up, its CNCS fashion colour atla just contains 900 kinds of colors, and the color kind of general fabric or coloured Spinning process enterprise all reaches thousands of kinds.
In traditional textile garment production procedure, be all generally first spin, poststaining, i.e. yarn dyeing after spun yarn, or yarn is made into cloth dyeing after cloth, and the appearance of colour-spun yarns technology, changes this flow process.So-called colour-spun yarns is exactly first fiber is dyed colored fibre, then by the fiber of two or more different colours after fully mixed, be spun into the yarn with unique color blending effect and product style.Because colour-spun yarns is owing to adopting the new technology of " first dye, rear spinning ", change the dyeing and finishing mode of textile production industrial chain, thus make process of producing product environmental protection and energy-conservation more.Therefore, the soft fashion of color, the colour-spun yarns that small lot multi items produces flexibly can be tackled, be applied in medium-to-high grade clothing products more and more, thus there is good market development prospect.
Chinese invention patent 201110025570.2 discloses the production method of a kind of regenerated celulose fibre and cotton blended colored yarns, carries out blending obtain regenerated celulose fibre and cotton blended colored yarns with white, red, yellow, blue, purple, orange, green, black regenerated celulose fibre and cotton.But it needs to prepare nearly 8 kinds of monochromatic colored fibres, and production cost remains high, and all there is different characteristics because of various fiber, as the difference of fineness, length, the difference of dyeability, to the requirement of production environment and the difference of spinnability, all affects the production of multicomponent blended yarn.Therefore, reduce the kind of colored fibre, and comprehensive study is carried out to the aspect such as blended weave, state modulator of regenerated cellulose staple fibre and polyester staple fiber two types of fibers, make the production of multicomponent blended yarn can meet the abundant requirement of yarn quality and color and luster, can significantly reduce production cost again and become the task of top priority.
Summary of the invention
For the problems referred to above, the invention provides the manufacture method of the two component blended yarn of a kind of colored fibre, need monochromatic fiber species few in the method but color and luster after colour mixture enriches, and low cost of manufacture, be reduced to minimum on the impact of environment.
For achieving the above object, the present invention is achieved through the following technical solutions:
