Problems solved by technology

[0004] By changing the original guide rollers for processing rope-shaped gray cloths into guide rollers for processing gray cloths in the open-width state, the gray cloths are unfolded into and out of the cloth during the processing process, so that not only the heat treatment is uniform during the alkali weight reduction process, but also saves The link of artificial dehydration and opening width is eliminated; however, a large amount of treatment solution is input at one time, and some polyester hydrolyzate will be produced in the gray clo

Abstract

The invention discloses an open-width alkali weight reduction machine and relates to the technical field of alkali weight reduction machines. The technical scheme is characterized in that the open-width alkali weight reduction machine comprises a cloth feeding device, an alkali treatment unit, a heating unit, a steam washing unit and a cloth placing device which are arranged sequentially, whereina tensioning device for guaranteeing non-looseness of grey cloth is arranged between the cloth feeding device and the alkali treatment unit; two-roll padders capable of removing residual liquids fromthe grey cloth by rolling are arranged between the alkali treatment unit and the heating unit, between the heating unit and the steam washing unit as well as between the steam washing unit and the cloth placing device; an oven is arranged between the cloth placing device and the two-roll padder close to the cloth placing device. Staining with alkali liquor, heating for hydrolysis promotion as wellas cleaning are performed on the grey cloth separately, so that consumption of the alkali liquor is reduced, concentration of the alkali liquor keeps unchanged, and the bath ratio of the grey cloth keeps consistent.

Description

technical field [0001] The invention relates to the technical field of alkali weight reduction machines, more specifically, it relates to an open-width alkali weight reduction machine. Background technique [0002] The alkali reduction process is mostly a process of treating polyester fabrics in high temperature and lye, using lye to hydrolyze and corrode polyester fabrics to promote the relaxation of fiber fabrics, reduce their quality, reduce fiber diameters, and form pits on the surface, making The fabric feels soft, has soft luster, improves moisture absorption and perspiration, and has a silk-like style, thereby achieving a production process for fabrics with a real silk feel. [0003] The Chinese patent whose publication number is CN104294504B discloses a kind of open-width alkali weight reduction machine, which includes a cabinet body, a cloth feeding device in the cabinet body, a cloth outlet device, a treatment solution, and a treatment solution heater. The improvem...
