Abstract

The invention discloses a non-formaldehyde discharging plasmogen and a preparing method and application of the plasmogen. Modified plant seeds adhesive paste by quality portion and thiourea dioxide are put into a mixer with a proportion of 1-3:1, 10-40 water is added and stirred for 1-2 hours; then the non-formaldehyde discharging plasmogen can be made. Then the non-formaldehyde discharging plasmogen is made into discharge printing white discharge pulp used for discharging white printing or into discharge printing colored discharge pulp used for discharging colored printing. The invention solves the problems of free formaldehyde releasing, bad stability, large consumption and high cost caused by the existing discharge agent, provides the non-formaldehyde discharging plasmogen and the preparing method and application of the plasmogen, assures a high white discharge degree when discharging white printing and assures bright color when discharging colored printing and outstandingly displays the unique style and character of the fine pattern of discharge printing.

Description

technical field [0001] The invention relates to a formaldehyde-free discharge dyeing pulp and a process for preparing and applying the formaldehyde-free discharge dyeing pulp for discharge printing discharge pulp. Background technique [0002] Discharge printing is a printing process that uses a discharge agent to partially destroy and abolish the ground color dye of the fabric, and then print a pattern; in this printing process, the printed white pattern is called white discharge printing, and the printed color pattern is called white discharge printing. called color pull. Dye discharge agent is the key drug for the realization of discharge printing. Discharge agent can destroy the bonding bond between ground color dye and fiber under high temperature and humid conditions, or directly destroy the structure of ground color dye, so that it can be decomposed into colorless or colored However, it is an intermediate that is soluble in water or other solutions, so as to achieve ...
