Production method of thermal transfer printing base paper

Abstract

The invention discloses a production method of thermal transfer printing base paper. The method comprises raw material pulping and washing and concentrating technologies. The production method is characterized by comprising the steps that raw materials are subjected to circulating intermittent pulping in a pulper, biological enzyme and sodium hydroxide are added simultaneously to achieve sufficient fiber softening and defibering, and raw material broken pulp is obtained; the pulp obtained through pulping is washed and then concentrated; meanwhile, a press felt is optimized and used. In this way, according to the production method of the thermal transfer printing base paper, chemical substances affecting transfer printing dyeing can be removed from the pulp, and therefore recessive white spots of transfer printing paper are reduced.

Description

technical field [0001] The invention relates to a production method of thermal transfer printing base paper. Background technique [0002] Transfer printing is one of the more popular printing methods today. Its advantages are artistic patterns, fine outlines, clear layers, lifelike shapes, relatively simple processing, and no pollution, less investment, energy saving, and small equipment footprints. [0003] At present, commercially available transfer printing papers generally use disperse dyes as colorants, which are vapor phase transferred to hydrophobic fabrics at high temperatures. The main raw material is transfer printing base paper, and its main performance is also determined by transfer printing base paper. Thermal transfer printing base paper is easy to produce recessive white spots after dyeing, and some uncolored spots appear on the transfer printing paper with high requirements for dark and gradual colors, and appear as clear white spots after the transfer print...

AI Technical Summary

Problems solved by technology

Thermal transfer printing base paper is easy to produce recessive white spots after dyeing, and some uncolored spots appear on the transfer printing paper with high requirements for dark and gradual colors, and appear as clear white spots after the transfer printing base paper is dyed. When it is transferred to the fabric, the same uncolored white spots will appear, which will cause the dyed fabric to fail to meet the requirements. If the quantity is too large, the dyed fabric will be scrapped.
