Device for conducting salt-free dyeing on cotton textiles without scouring and bleaching by adopting activated dye

Abstract

The invention discloses a device for conducting salt-free dyeing on cotton textiles without scouring and bleaching by adopting activated dye. The device comprises a dip dyeing device, an extruding device and a drying device, the dip dyeing device, the extruding device and the drying device are successively arranged, and the dip dyeing device comprises a dyeing pond; a groove is formed in the dyeing pond, two fixed plates are fixedly and symmetrically connected to the side wall of the groove, and first guide rollers are rotatably connected to the ends, away from one end of the bottom side wallof the groove, of the two fixed plates. Through mutual effect of the first guide rollers and second guide rollers, a woven fabric passes through the inside of the dyeing pond to be subjected to dip dyeing, through extruding of two extruding rollers, excess water of the fabric after dip dyeing is extruded out, the woven fabric enters into a shell body through an inlet and is wound on a heating roller to be ironed, and therefore wrinkles generated from extruding of the fabric are ironed flat, and the fabric is more attractive; through a draught fan and a fan cover, the upper and lower sides of the fabric are blown by air, so that the fabric is dried.

Description

technical field [0001] The invention relates to the technical field of cotton textile processing, in particular to a device for salt-free dyeing of unboiled and bleached cotton textiles with reactive dyes. Background technique [0002] Cotton textiles are cotton, silk and other cotton raw materials that are woven into a complete cloth by hand or machine. The cotton textile industry plays an important role in the development of my country's national economy. It spans the two major production areas of agriculture and industry, and involves multiple links such as cotton production, ginning, spinning, weaving, printing and dyeing, garments and terminal consumption. It has become one of the pillar industries of my country's national economic development. The process of cotton spinning process is also suitable for spinning cotton-type chemical fiber yarn, medium-length fiber yarn and blended yarn of cotton and other fibers. Cotton fabric has good wearing performance, low price, a...

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the dyes in the dyeing tank in the existing dyeing device are easy to precipitate, thus causing uneven dyeing, and the textiles after dyeing are generally directly dried or blown by a blower. Drying, and a large amount of dyeing liquid remains on the textile after the infection is completed, which increases the time for drying and drying, and wastes resources at the same time. In addition, the textiles after drying in the prior art will have wrinkles, which will cause the textiles to shrink after they are rolled. Unevenness, which affects winding
