Abstract
The invention discloses a yarn dyeing method with a controllable ring dyeing effect and an indigo-dyed yarn. The yarn dyeing method comprises the following steps of performing boiling-off treatment on cotton yarns ; performing soft finishing on the cotton yarns; performing waterproof treatment on the cotton yarns; performing baking treatment on the cotton yarns; performing polyurethane padding treatment on the cotton yarns; by taking short fibers as an outer wrapping fiber layer and the cotton yarns as core yarns, carrying out core-spun yarn process treatment on a spinning frame to form a core-spun yarn structure; carrying out beaming; carrying out indigo dyeing treatment on core-spun yarns; carrying out oxidation treatment on the core-spun yarns; washing the core-spun yarns with water; and drying the core-spun yarns. According to the yarn dyeing method with the controllable ring dyeing effect provided by the invention, boiling-off treatment does not need to be conducted on the yarns, original wax and impurities of the yarns are combined with a waterproof layer, outer wrapping fibers of the core-spun yarns are colored, and core yarns are not colored, so that the effect that the yarns are subjected to ring dyeing through the indigo dye is achieved, and the ring dyeing effect of the yarns can be adjusted by controlling the thickness of the core yarns and the thickness of the outer wrapping fibers.
Description
technical field [0001] The invention relates to the field of dyeing and finishing technology of denim fabrics, and mainly relates to a yarn dyeing method with controllable ring dyeing effect and indigo yarn. Background technique [0002] Denim clothing is an evergreen tree in clothing. After more than one hundred years of evolution and development, it has been loved by people. It is not the style design of the clothing that makes it on the forefront of fashion, but the variety of finishing. process, and the washing process is an important part of the finishing process, and it is an important link that reflects the added value of denim clothing. Through different washing processes and links, denim clothing has ever-changing styles to meet market demand and improve market competitiveness. . [0003] Indigo denim fabric is made of cotton yarn dyed with indigo dye and natural white weft yarn in a 3 / 1 twill structure. Indigo dye is a vat dye, insoluble in water, and only after ...
