Problems solved by technology

At present, dyeing factories use good quality imitation reactive printing adhesives to achieve the purpose of soft hand feeling, but for some dark varieties, the dry rubbing fastness index is difficult to meet the requirements of level 4
[0003] Chinese patent CN104831535 A discloses a dry rubbing fastness improving agent which is applied to fabrics by padding or dipping process to effectively improve its dry rubbing fastness. The fabrics emphasized in this patent are dyed fabrics with sulfonic acid dyes, which are not suitable for pigment printing the fabric
At the same time, the dry rubbing fastness improving agents in the above patents and research papers are all loaded by padding or dipping process, and there is no selectivity to the color depth. It is suitable for dyed fabrics, but this process will cause waste for printed fabrics.
Zhejiang Jiaxin Xingchang Printing and Dyeing Co., Ltd. Liu Hongdong and others improved the dry rubbing fastness by increasing the amount of adhesive, but if it exceeds a certain limit, it will not only easily block the mesh but also make the fabric feel hard, and the friction coefficient will increase instead, resulting in a decrease in dry rubbing fastness
However, increasing the degree of film crosslinking by adding crosslinking agents and catalysts has a significant effect on improving the wet rubbing fastness of pigment printed fabrics, but it tends to decrease the dry rubbing fastness.

Abstract

The invention discloses a dry rubbing fastness improver for a pigment printing fabric as well as a preparation and using method of the improver. The dry rubbing fastness improver for the pigment printing fabric comprises the following components in percentage by weight: 50-80% of a lubricating agent, 5-8% of a cross-linking agent, 0.5-2% of a thickening agent, and 10-44.5% of deionized water. The method comprises the following steps: accurately weighing the various components, uniformly stirring, and preparing the dry rubbing fastness improver for the pigment printing fabric with a viscosity range of 20000-30000mPa.s; directly adding 0.1-2% of the dry rubbing fastness improver for the pigment printing fabric into the prepared coating printing size, completing printing by using rotary screen printing or flat screen printing, drying and roasting, so that the dry rubbing fastness of the pigment printing fabric can be improved to level 4.

Description

technical field [0001] The invention relates to an agent for improving the dry rubbing fastness of pigment printing fabrics and a preparation and use method thereof, belonging to the technical field of textile pigment printing. Background technique [0002] Pigment printing is a printing process that uses adhesives to adhere pigment particles that are not reactive to fabrics to fibers to obtain desired patterns, so the quality of the adhesive determines the feel and fastness of pigment printing products. At present, dyeing factories use good quality imitation reactive printing adhesives to achieve the purpose of soft hand feeling, but for some dark varieties, the dry rubbing fastness index is difficult to meet the requirements of level 4. [0003] Chinese patent CN104831535 A discloses a dry rubbing fastness improving agent which is applied to fabrics by padding or dipping process to effectively improve its dry rubbing fastness. The fabrics emphasized in this patent are dyed...
