Device and method for printing and dyeing and transferring steaming-free water-scrubbing-free reactive dye

Abstract

The invention relates to a device and a method for printing and dyeing and transferring a steaming-free water-scrubbing-free reactive dye, which is used for machinery for transfer-printing in dyeing and finishing industries. According to the invention, the device comprises a tensionless conveying guide belt and a tension-regulating guide roller group; any shell fabric is fed into a repeatedly-wetting fluid bath device with a scraper; after the shell fabric is wetted, the shell fabric enters a transfer-printing pressing roller group and a first group of baking drums; the shell fabric is subjected to fixation through a meshed concave roller of a fixating fluid bath with a scraper and a pressing roller fixating group and enters a second group of braking drums while a softening agent is added; and the outlet product enters a product reel. In the invention, a water-soluble transfer-printing technique is adopted, thus the method is energy-saving and has low investment; through only once hot-pressing transferring at the highest temperature of 100 DEG C and then baking, the shell fabric can be fully fixated without waste material, waste gas and water scrubbing, thus the device and the method for printing and dyeing and transferring of the steaming-free water-scrubbing reactive dye satisfy with the standard 100 of ecological textiles.

Description

technical field [0001] The invention relates to a transfer printing machine in the dyeing and finishing industry. Background technique [0002] Transfer printing has been a dyeing and finishing industry that has shifted from traditional dyeing and printing to environmental protection. Therefore, the rivers beside some dyeing and printing factories have changed from colorful sewage full of rivers in the past to slightly clear water, which is environmentally friendly. With the advancement, there are several types of transfer printing, so there are several types of machines involved. Among them, there is a "roller transfer printing device for cold transfer printing machine ZL20072002965.7", which uses three pairs of roller transfer printing devices. , before the cold transfer printing process, there is a pretreatment device for the fabric to be printed, and after the cold transfer printing process, there is a reel of the transferred fabric. According to the patent introduction...

Problems solved by technology

Although my country has made great progress in this type of machine, the natural fiber transfer printing on the market currently mainly uses the cold stacking method. Before the transfer, it needs to be impregnated with alkali, sodium alginate and urea, and then transferred. Constantly rotate to achieve the purpose of color fixation, and then wash with water. The quality of the finished product is unstable, and water marks are prone to appear. There is a lot of alkali, sodium alginate and unfixed dye on the fabric, which must be washed with water.

At the same time, it consumes energy and discharges a large amount of sewage

In terms of the impact of scratching, the pattern does not deform, the three wastes still have one or another deficiency, resulting in unsatisfactory product quality and environmental protection.
