Problems solved by technology

[0003] The traditional tank washing production process has a high bath ratio, consumes a lot of water, electricity, and steam, and discharges a large amount of wastewater. Complicated operations such as feeding, heating, and cloth feeding, as well as multiple feeding operations are prone to human errors, and at the same time reduce the need for dehydration and opening after laundering, which is more cumbersome

Abstract

The invention discloses a after-printing washing process, comprising the following concrete operation steps: feeding cloth; spraying and washing; performing fixation; spraying and washing again; and discharging cloth by vacuum pressure suction, wherein a CD anti-staining agent, a KNR dye-fixing agent, sodium carbonate, acetic acid and an anti-staining soaping agent are used in the spraying and washing process. The process has the advantages that the assistant cost can be effectively saved, water consumption can be saved, sewage discharge is reduced, and the positive impelling action is taken for energy conservation and emission reduction. The process is capable of achieving automatic control, so that the quality of a washed product is consistent from beginning to end, dyelot chromatism and spline difference, which easily appear in a traditional cylinder scoring intermittent water washing process, are avoided, and the quality of the washed product is relatively stable; complex operations such as manual feeding, warming and cloth feeding in the traditional cylinder scoring washing process are avoided, meanwhile, two procedures of dehydration and scutching during the later period of cylinder scoring washing are omitted, and thus the operation is relatively simple; therefore, the payroll cost is effectively saved, meanwhile, the production efficiency is greatly improved, control on energy consumption is effectively improved, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a washing process, in particular to a washing process after printing. Background technique [0002] In the traditional tank washing production process, the first step is to add cold water containing anti-stain soaping agent and soda ash for 10 minutes, and the bath ratio of cleaning solution to gray cloth is 1:30; the second step is to add anti-staining soaping agent Wash with soda ash in warm water at 40°C for 20 minutes, in which the bath ratio of the cleaning solution to the gray cloth is 1:30; in the third step, wash with cold water for 10 minutes, in which the bath ratio of the cleaning solution to the gray cloth is 1:30; in the fourth step, add acetic acid to adjust the pH value To 4-5, wash with cold water for 10 minutes, wherein the bath ratio of the cleaning solution to the gray cloth is 1:30; the fifth step is to fix the color with cold water containing KNR color fixing agent for 10 minutes, and the bath ratio of the ...
