Efficient energy-saving desizing machine

Abstract

The invention relates to the technical field of dyeing and weaving equipment, in particular to a desizing machine for removing sizing agent impurities obtained after cold stacking of nylon and polyester mixed fabrics. The desizing machine comprises a machine frame, a plurality of driving motors for providing power, a heating device for supplying heat to the whole machine and an automatic control system for controlling operation of the whole machine. A cloth feeding mechanism, a charging tank, a plurality of desizing mechanisms, a plurality of washing mechanisms and a cloth discharging mechanism are sequentially arranged on the machine frame in an assembly line mode. The charging tank, the desizing mechanisms and the washing mechanisms are connected with the heating device. Padders for performing squeezing and liquid pressing on cloth and keeping a certain cloth pick-up ratio are arranged between two adjacent desizing mechanisms, between two adjacent washing mechanisms, between the desizing mechanisms and the washing mechanisms, between the charging tank and the desizing mechanisms and between the washing mechanisms and the cloth discharging mechanism respectively. A circulating pump for achieving water circulation is arranged between every two adjacent washing mechanisms. The desizing machine is used for the desizing production technology in cloth dyeing and weaving.

Description

technical field [0001] The invention relates to the field of dyeing and weaving equipment, in particular to a desizing machine for removing impurities in slurry after cold stacking of nylon and polyester interwoven fabrics. Background technique [0002] The textile printing and dyeing industry is an industry with high energy consumption, high water consumption, and high pollution. In today's energy shortage, water resource shortage, and environmental deterioration, it is of great significance to realize the recycling of equipment energy. Desizing is an important process in production in this industry. Desizing is the process of removing sizing on fabrics. The warp yarns of fabrics such as cotton, viscose and synthetic fibers are mostly sizing before weaving. During the dyeing and finishing process, the size will affect the wettability of the fabric and hinder the contact of chemicals to the fiber. Therefore, the fabric is generally desized first, and the desizing of the cot...

AI Technical Summary

Problems solved by technology

[0004] In actual production, after a certain working time of the desizing mechanism, a large amount of sizing and impurities remain in the desizing box. After the subsequent cloth enters, it is easy to form anti-sticking of the sizing and impurities on the cloth, which affects the subsequent washing mechanism. Washing effect will cause the fabric to be dirty, and the fabric will feel hard after desizing, which will affect the subsequent fabric dyeing process
