Abstract

The invention belongs to the technical field of textile printing and dyeing and in particular relates to a disperse/reactive dye modification one-bath dyeing technology for polyester-cotton/viscose fabric. The fabric is modified through color media or other modifiers, environment-friendly carriers are added into two disperse/reactive dye solutions, and a salt-free alkali-free or salt-free low-alkali normal temperature dyeing technology is implemented by using a one-bath two-step method. The technology has the advantages of simple process, convenience for operation and short dyeing time, a great amount of salt and alkali can be saved, energy sources are saved, and cost is reduced. By respectively adding a cross bond agent or a pH slippage agent or a small quantity of alkali agents into a dye bath, requirements for high fixation rate and high color fastness are met, and the technology is substantively changed and improved obviously by employing dye bath. Therefore, the technology has high social and economic benefits and a broad prospect.

Description

Polyester-cotton blend/binding textiles dispersion/REACTIVE DYES modification one-bath process technology

Technical field

The invention belongs to technical field of textile printing, relate in particular to a kind of polyester-cotton blend/binding textiles with dispersion/REACTIVE DYES modification one-bath process technology.

Background technology

Polyester-cotton blend/binding textiles is the conventional big series products of textiles, generally will select two kinds of dyeings for use, and disperseing with active two kinds of dyestuffs is main dyestuffs of polyester-cotton blend/binding textiles dyeing; They are used for dying polyester and cellulose fibre respectively, and these two kinds of dyeing performances and process conditions difference are big, adopt normal dyeing technology mostly; Promptly earlier use disperse dyeing of polyester, use the REACTIVE DYES resisdye cotton again, the whole dyeing time is long; Working (machining) efficiency is low, and water consumption power consumption and quantity of wastewater effluent are big.

Along with government's environmental protection policy requires down, environmental requirement improves constantly, and in order to improve problems such as water, the energy, environmental pollution, the protection environment reduces and pollutes, and the short flow process dyeing and printing process of research energy-saving and emission-reduction seems very important.

In recent years; There are many colourist's research and development to develop polyester-cotton fabric dispersion/active single bath process exhaust process; Mostly seek moderate property mediation contradiction from both dyeing performances, still have the dyestuff hydrolysis, dye dark difficulty and staining fastness problem, existence need be dyed dyeing with a large amount of salt, alkali and high temperature; Consume the money ability, influence environment.

Summary of the invention

For the above-mentioned big situation of energy consumption that exists ,Design meets and cuts down the consumption of energy, and reduces ambient influnence, and process for cleanly preparing has very important function, and the design promotes dye-uptake to fabric-modifying, cuts down the consumption of energy.

The design improvement scheme: fabric-modifying, cotton with look medium and the processing of other modifier, terylene is handled with the modification of environment-friendly type dyeing accelerant.

The existing a lot of reports of vital staining technology are handled in the COTTON FABRIC modification; Needn't lay down a definition at this, the dyeing and finishing worker can reach the reactive dye salt-free non-alkali dyeing after understanding cotton modification the sixth of the twelve Earthly Branches, and the present invention is statement BLENDED FABRIC cotton and washs and disperse and active modification dyeing; Can reach and cut down the consumption of energy; Secondly, be how to improve COLOR FASTNESS better, satisfy the high color fastness requirement.

Modifier is selected for use: the look medium of more preferential available dolantin, the modifier of Donghua University.

Dyeing accelerant is selected for use: must select environment-friendly type for use, have that the swollen effect of rising has had simultaneously the level-dyeing property effect again to terylene.

Improved purpose: 1. reach the salt-free alkali-free of dyeing after the modification, reach conventional COLOR FASTNESS requirement, 2. reach salt-free alkali-free or salt-free low alkali after the modification, satisfy more high color fastness requirement.
