Abstract

The invention provides a yarn dyeing method, and belongs to the technical field of textile related equipment. The technical problems that for an existing dyeing method, the dyeing efficiency is low, and dyeing is inconvenient are solved. The yarn dyeing method comprises the steps of 1, yarn preparation and inspection, wherein the yarn quality is inspected before yarn dyeing is conducted, and it is required that the appearance of yarns is clean and free of stain, the yarns are neutral, the stacking time must not be over 8 h, and the yarns are covered with wet cloth; 2, feeding, wherein yarns are put into a dye vat and arranged on a yarn dyeing rod; 3, dye preparation, wherein anthraquinone vat dye is prepared in a dye barrel, 5 g-6 g of caustic soda and 5-6 g of rongalite are added according to each part by mass of raw material with an anthraquinone type structure, water is injected to obtain a solution, and 0.2 g / L-0.5 g / L of bone glue retarding agent is added; 4, dye injection and dyeing, wherein the prepared dye is injected into the dye vat; 5, yarn taking-out. The yarn dyeing method has the advantages of being high in dyeing efficiency and uniform in dyeing, and the yarns subjected to dyeing is fluffy and full in hand feeling.

Description

Technical field [0001] The invention belongs to the technical field of textile-related equipment, in particular to a yarn dyeing device and a yarn dyeing method. Background technique [0002] Yarn is processed into products with a certain fineness from various textile fibers, used for weaving, rope making, thread making, knitting and embroidery, etc.; yarn is divided into short fiber yarn, continuous filament, short fiber and continuous filament combined yarn Etc., staple fiber yarn is processed by spinning staple fiber, divided into ring-spun yarn, open-end spinning, self-twisted yarn, etc.; continuous filaments such as natural silk and chemical fiber filaments, added twisted or not twisted, smooth Filament or textured filament, etc.; short fiber and continuous filament combined yarn, such as polyester-cotton filament core-spun yarn. With the improvement of people's living standards, the requirements for rich colors are getting higher and higher, and the yarns usually made need...
