Denim pigment dyeing technique with laser modifying function

Abstract

A technique for dyeing denim paint which is provided with laser modification action is disclosed and relates to a technique for weaving, in particular to a technique for dyeing denim paint, which comprises the following steps: firstly, unwinding a denim (9) from a winding roller through a fabric guide roll (1), and then entering in the laser illumination area to do laser process, making the denim (9) processed by laser enter on the upper surface of a pallet (6), entering the denim (9) which is provided with the paint under a scraper (4), finally, conducting the dyed denim into the next procedure by a fabric guide roll (5). The technique for dyeing denim paint greatly improves the dye-uptake of paint dye. The structure change of the processed material is almost limited in the thin surface scale, which doesn't influence the body property of the fiber material.

Description

Technical field: [0001] The invention relates to a weaving process, in particular to a denim paint dyeing process. Background technique: [0002] The textile printing and dyeing industry is a large water user and an important source of wastewater pollution. With the increasingly fierce market competition, the strict accounting of production costs and the pressure of environmental protection make printing and dyeing enterprise managers more willing to accept energy-saving, water-saving and cost-reducing coatings. Dyeing, on the other hand, due to its non-selectivity to fibers and its short process, convenient color matching, energy saving and water saving, low cost and other advantages, paint dyeing is widely used in cotton, hemp, silk and their blended fabrics to replace The traditional dyeing process of the original active dyes, direct dyes, vat dyes, and Indicosol dyes has a long dyeing process, large consumption, and high cost of dyes and chemicals. There are broad marke...

Problems solved by technology

However, paint dyeing also has shortcomings, such as mechanical fixation determines its poor rubbing fastness, especially the rubbing fastness is not high

Although new adhesives have emerged in recent years and the color fastness of paint dyeing has been improved to a certain extent, it cannot completely replace the traditional dyeing process.
