Towel temperature sensitive printing process

Abstract

The invention relates to a towel temperature-sensitive printing process. The specific steps of the printing process are as follows: Step 1 is to prepare printing paint: 60-70 parts of modified silicone resin emulsion, 1-5 parts of heat-sensitive discoloration agent, and 0.5-1 part of thickener 1 part, 0.5-1 part of dispersant, 15-20 parts of solvent, mix and heat, the stirring time is 2.5-3.5h, the heating temperature is 50-70°C, and the solvent is added repeatedly during the heating and stirring process to maintain the viscosity of the printing paint at 8 Between ‑10Pa•s, after cooling down to below 35°C, the material is discharged to obtain a printing paint; wherein, the thermosensitive discoloration agent is a higher aliphatic alcohol, a phenolic compound, and a triarylmethane compound in a mass ratio of 0.2:0.4:0.4 The mixed mixture of the ratio; step 2 is printing paint coating: apply the uniformly mixed printing paint on the surface of the towel gray cloth, and the number of coating layers is 1-3 layers; step 3 is drying of printing paint: apply The finished towel gray cloth is dried at a temperature of 100°C-120°C and a drying time of 20-30min. The invention has the effect of enabling the towel to have a temperature-sensing and color-changing function.

Description

technical field [0001] The invention relates to the technical field of towel production and processing, in particular to a towel temperature-sensitive printing process. Background technique [0002] Towels are woven fabrics made of textile fibers, with loop piles or cut piles on the surface. Generally, pure cotton yarn is used as raw material, and a small amount is mixed with blended yarn or chemical fiber yarn, and it is woven on a towel loom. The method of using the towel is to wring out the skin after getting wet, so as to achieve the effect of removing stains, cleaning and cooling. With the development of science and technology, towels have developed from the simplest single-color flat wool towels to satin jacquard, printed, untwisted, cut pile and other materials. It is the textile product with the shortest development time and the fastest development speed. According to the weaving method, towels are divided into two categories: knitting and woven; The surface of th...
