Problems solved by technology

[0002] The dyeing of cashmere and silk scarves mostly adopts the high-temperature dyeing technology of acid dyes, so the color of the dyed products is relatively single, and it cannot show rich and colorful color changes
In addition, when ultra-thin, high-count or loose-structure cashmere and silk are printed and dyed on traditional dyeing machines, due to the high tension of the equipment, the fabric is prone to deformation and the damage to the fiber is greater

Abstract

The invention discloses a processing method suitable for distant-dyeing on cashmere and true silk scarves. The processing method includes processing steps of printing photochromic slurry; adsorbing intermittent chromotropic dye; carrying out steaming fixation; carrying out hot washing; carrying out drying treatment. The processing method has the advantages that the distant-dyed cashmere and true silk scarves prepared by the aid of the processing method are excellent in color fastness and feel soft; the processing method is high in operability and suitable for industrial production.

Description

Technical field [0001] The invention relates to a processing method suitable for section dyeing and dyeing of cashmere and silk scarves. Background technique [0002] The dyeing of cashmere and silk scarves mostly uses high temperature dyeing technology with acid dyes, so the color of the dyed products is relatively single, and can not show a variety of color gradations. In addition, when ultra-thin, high-count, or loose-structured cashmere and silk are printed and dyed on a traditional dyeing machine, the fabric is prone to deformation due to the high tension of the equipment and damages the fibers. [0003] Section dyeing is mainly used for the dyeing of yarns, that is, different colors are displayed on a yarn at the same time. The choice of dye type depends on the nature of the fiber, and the dyeing principle is similar to ordinary dyeing methods. The difference with ordinary dyeing methods is that the dyeing solutions composed of dyes of different colors are applied differentl...
