Problems solved by technology

However, in practical applications, it is found that there are uneven dyeing in different regions in the fabric after dye printing.
This may be due to the fact that the dye concentration is too high in a certain period of time during dyeing, resulting in the dye not being able to spread evenly to each area of ​​the fabric in time, and the dye concentration in different areas is different

Abstract

The invention aims at providing a printing paste for silk fabric and a printing technology with the printing paste. Dye printing evenness can be improved. The printing paste comprises, by weight, 20-100 parts of capsule cores, 1-20 parts of bonding agent and 5-30 parts of capsule films; the capsule cores comprise, by weight, 1%-10% of dye, 1%-5% of urea and 30%-60% of paste materials; the capsule films comprise, by weight, 5%-20% of vinyl acetal polymers and 80%-95% of polyether and / or polyolefins copolymers. The printing technology with the printing paste includes the following steps that S1, the silk fabric is pretreated; S2, the printing paste is prepared with the method; S3, under the condition that pH is equal to 6.0 to 6.5, the printing paste prepared in the S2 is used for printing the silk fabric pretreated in the S1; S4, the printed silk fabric obtained in the S3 is dried, aged, cleaned and finished.

Description

technical field [0001] The invention relates to the technical field of textile printing, more specifically, it relates to a printing color paste for silk fabrics and a printing process using the printing color paste. Background technique [0002] Silk generally refers to silk, including mulberry silk, tussah silk, castor silk, cassava silk, etc. Silk, which belongs to protein fiber, is a nitrogen-containing polymer compound composed of sericin and silk fibroin. Sericin is outside and silk fibroin is inside and the two are closely connected. Silk is also a kind of porous fiber, which is composed of 18 kinds of amino acids that are beneficial to the human body in different proportions and spaces. Silk fabrics are favored by people throughout the ages for their good moisture absorption, breathability, and skin care and health care functions. [0003] With the development of society, the diversification of silk fabrics has become a demand of the times, and printing on silk fab...
