AI Technical Summary

Problems solved by technology

Its disadvantages are: (1) When scouring, the working fluid volume is large (about 3500L), so it is suitable for concentrated scouring and bleaching, and the continuous production is 150,000 meters
(2) The scouring agent has high requirements. At 30-50g / L NaOH, at 100°C, it needs to be kept for 80 hours without deterioration, let alone floating oil
[0006] At present, there is no public literature about such short-flow pretreatment technology

Abstract

The invention provides an efficient short-flow pre-treating process for high-grade high-density cotton fabrics in order to remove the impurity and slurry from cotton woven. The process comprises the steps of feeding cloth, hot washing, padding enzyme solution, steaming, hot washing, warm washing, padding floating solution, wet steaming, hot washing, warm washing and drying. The specific step is to desize with wide-temperature enzyme on a pre-treated desizing section, boiling, whitening a whitening section with alkali oxygen technique and a wet short steaming device in order to remove the impurity and slurry from cotton fibers, for the purpose of shorting the process flow and decreasing the consumption. The invention has the advantages that (1) the process flow is shortened, the working efficiency is promoted and the product quality is promoted, (2) the harmful wastes are decreased and the environment is protected, and (3) the consumption of water, steam and energy is decreased and the manufacturing cost is lowered.

Description

(1) Technical field [0001] The invention relates to a fabric printing and dyeing pretreatment process in the textile field, in particular to an efficient short-flow pretreatment process applied to high-count and high-density pure cotton fabrics. (2) Background technology [0002] With the implementation of circular economy laws and regulations, saving energy and reducing pollution emissions will become a basic national policy of our country and a long-term strategic task. Due to the increasing contradiction between the rapid economic development and energy supply and demand, energy prices have been rising continuously in recent years, and the proportion of energy consumption costs and enterprise costs has increased year by year. In order to make the product price competitive, it is necessary to do everything possible to reduce the cost, and improving the process is one of the effective ways to save energy and reduce emissions. [0003] Cotton fabrics need to be pre-treated ...
