Abstract

The invention relates to a novel oil removing and setting process and device for chemical fiber fabric production. The process of the oil removing and setting device comprises the following steps of ultrasonic oil removing, padder squeezing, shaping padder squeezing, high-temperature primary setting and transferring to dyeing or printing. The invention aims to provide a novel oil removing and setting process for chemical fiber fabric production. According to the oil removing and setting process, no chemical additive is needed in the oil removing process; only a certain amount of water is usedas a medium (or a part of chemical additives can be used), and oil on the fibers is dispersed and 'refined 'by utilizing a cavitation effect generated by ultrasonic oscillation and then enters a setting machine to be completely evaporated, so that the oil removal effect of an original gray fabric oil removal washing process can be achieved, and the requirements of energy conservation, emission reduction and environmental protection are met. The oil removing equipment is mounted in front of the setting machine, continuity of gray fabric oil removing and setting production is realized, the production process is shortened, the production efficiency is improved, the labor intensity is reduced, and more quality guarantee is provided for subsequent processing.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a novel degreasing and shaping process and a device thereof for the production of chemical fiber fabrics. Background technique [0002] In the traditional textile chemical fiber fabric degreasing and shaping process (attached figure 1 As shown), the gray cloth is soaked in degreaser and alkali agent at high temperature (about 80°C) by an open-width (rope-shaped) degreasing water washing machine, and then washed with clean water and squeezed (dehydrated); or dry-cleaned with solvent tetrachlorethylene to degrease , and then transferred to the setting machine for initial setting at high temperature. Traditional continuous degreasing washing machine (attached image 3 (shown) covers a large area, has a long process flow, and consumes a lot of degreasing additives, water, electricity, and steam, which does not meet the current requirements for energy saving, emission reduction, and environm...
