Background

The yarn is a textile, is processed into products with certain fineness by various textile fibers, is used for weaving, rope making, thread making, knitting, embroidery and the like, and is divided into staple fiber yarn, continuous filament yarn and the like. There are various methods of expressing the fineness of the yarn, such as number, metric count, english count, denier, and the like. The twist of the yarn is expressed in turns per meter or inch. The wool yarn and the wool yarn are generally used for spinning woolen sweaters, woolen trousers, woolen vests, scarves, hats and gloves and weaving various articles for clothes in spring and autumn, and have the decoration effect besides the heat preservation effect.

The yarn is white, and the colored spun yarn is that the fiber is dyed into colored fiber, and then the fiber with two or more different colors is fully mixed to be spun into the yarn with unique color mixing effect. The colored spun yarn can realize hazy three-dimensional effect and texture which cannot be achieved by white blank dyeing. The colored spun yarn has no pollution in use, and the color difference can be controlled to the maximum extent. Therefore, the color spun yarn which is soft and fashionable in color and can be flexibly produced in small batches and multiple varieties is increasingly applied to middle-high-grade clothing products.

The main application of the colored spun yarn is in sweaters and woven belts. Different fabrics have ever-changing hand feeling for the yarns in order to pursue different styles; besides the idea of raw materials, the dyeing and finishing auxiliary agent can be used, and different types of auxiliary agents can be selected to achieve ideal effects. The main component of the most used softening agent in yarn dyeing is silicone oil. The quality of the hand feeling of the yarn is analyzed by touching the hand of an experienced worker for judgment, certain personal subjective judgment exists in the quality judgment by depending on the hand feeling, and the detection structure of the hand feeling is not accurate enough.
