High-light-color-fastness transfer printing method

Abstract

The invention relates to a high-light-color-fastness transfer printing method. An ink for transfer printing comprises the following components in percentage by mass: 40-70% of black disperse dye, 10-30% of red disperse dye, 12-15% of methanol and / or isobutanol, 5-10% of polyvinyl butyral and 3-5% of photostabilizer 622. The transfer printing method comprises the following steps: soaking a textile to be printed in a polyoxyethylene or polyoxypropylene water solution, and carrying out transfer printing. The invention has the advantages of simple technique and low cost; and the printed pattern has the advantages of high binding force with cloth, high light color fastness and high durability.

Description

technical field

[0001] The invention relates to the technical field of transfer printing, in particular to an ink for transfer printing and a method for improving the color fastness of transfer printing to light. Background technique

[0002] Color fastness, also known as color fastness and color fastness, refers to the resistance of the color of textiles to various effects during processing and use. Textiles will be subjected to various external effects such as light, washing, ironing, sweat stains, friction and chemicals during their use. Some printed and dyed textiles also undergo special finishing processes, such as resin finishing, flame-retardant finishing, sand washing, grinding, etc. Wool, etc., which requires the color of printed and dyed textiles to maintain a certain degree of fastness. Whether the color fastness is good or bad is directly related to the health and safety of the human body. When a product with poor color fastness encounters rain or sweat during w...
