Vacuum water-absorbing prepreg tank for wet cloth hot alkali straight roll mercerizing machine and its processing method

Abstract

The invention discloses a vacuum water-absorbing prepreg tank for a wet cloth hot alkali straight roll mercerizing machine and a processing method thereof, including a prepreg device, a rolling device and a cooling device. The prepreg device includes a tank body, and light alkali is arranged at both ends of the tank body The conveying device and the concentrated alkali conveying device, the light alkali conveying device and the concentrated alkali conveying device are all equipped with a liquid storage tank, the top of the tank body is equipped with a cloth inlet groove and a cloth outlet groove, and the inside of the tank body is equipped with a partition plate and a first The rotating roller, the partition plate is equipped with an alkali mixing device and a heating pipe, the cooling device includes a cooling frame and a cooling tank, the cooling frame is equipped with a driving roller, a positioning device, an air cooling device and a third rotating roller, and the cooling tank is equipped with a spray liquid device. The processing method includes: 1) soaking the cloth in hot alkali; 2) expanding the cloth; 3) cooling the cloth. The invention solves the problems that the existing mercerizing machine cannot specifically control the temperature and alkalinity of the hot alkali, and the cloth is prone to wrinkle and the expansion effect is not good, and the cooling efficiency is low.

Description

technical field [0001] The invention specifically relates to a vacuum water-absorbing prepreg tank for a wet cloth hot-alkali straight-roll mercerizing machine and a processing method thereof. Background technique [0002] In the prior art, cotton products (yarns, fabrics) are treated with a concentrated caustic soda solution under a certain tension, and then the process of washing away the caustic soda under tension is called mercerizing, and the mercerizing machine is mainly used for knitted fabrics. For dry and wet cloth mercerizing, the scoured (or singeed) open-width knitted fabric is soaked in concentrated alkali under tension. After a certain period of time, the alkali will change the cross section of the cotton fiber and expand it from a rectangular shape. It is round, the cell cavity shrinks, the longitudinal natural distortion disappears, and then the fiber is stretched or no longer shrinks under appropriate tension, the surface wrinkles of the fiber disappear, and...

Problems solved by technology

[0004] The purpose of the present invention is to aim at many deficiencies in the prior art, to provide a vacuum water-absorbing prepreg tank for a wet cloth hot-alkali straight-roller mercerizing machine and a processing method thereof, and to solve the problem that the existing mercerizing machine cannot specifically control the temperature and alkalinity of the hot-alkali. control, and the fabric is prone to wrinkles, poor expansion effect, and low cooling efficiency.
