Abstract

The present invention discloses a dyeing and finishing process for soybean fiber fabrics, which comprises bleaching, dyeing and post treatment techniques, wherein said bleaching process comprises steps of adding hydrogen peroxide of 8 g/L into water with a bath ratio of 1:10 at room temperature, heating the liquid to 70-80 DEG C and keeping it at the temperature for 20-30 minutes, adding promoter 197 therein and functioning for 5-10 minutes, heating the liquid to 90-100 DEG C and keeping it at the temperature for 40-60 minutes, washing it with water, acid and enzyme in turn, and lowering the temperature to a temperature desired by a dyeing, then dyeing it. By utilizing processes of warm wash and gas-bleaching by hydrogen peroxide with high concentration followed with a bleaching process of heating time-delayed oxygen-bleaching by adding pretreatment promoter 197, the present invention ensures that the bleaching whiteness of soybean fiber fabrics reaches beyond 60% under a standard light source, and resolves the problem that the bleaching whiteness of soybean fiber fabrics is not enough to exhibit an excellent effect when being dyed light colors and bright colors.

Description

The dyeing and finishing technology of soybean fabric lining

Technical field

The present invention relates to a kind of dyeing and finishing technology of soybean fabric lining, belong to technical field of textile printing.

Technical background

In short supply and the requirement on environmental protection along with global energy; chemical fibre can not satisfy people's needs; and ecological fiber is owing to extract from natural plant; compare with chemical fibre; have better quality and feel; and have the good recyclability and the feature of environmental protection, thereby more and more paid attention to by people.Fibre and soya is to extract protein and high polymer is a raw material from soybean, after new and high technology is handled, adopts wet spinning to form, because it has feel and warmth retention property preferably, and has antibiotic effect, therefore is with a wide range of applications.At present, fibre and soya is not promoted on a large scale, the principal element of restriction is that the fibre and soya pre-treatment process is a bleaching process, because fibre and soya is natural yellow, adopt traditional highly basic to add the bleaching process (shown in accompanying drawing 1) and the dyeing (shown in accompanying drawing 3) of hydrogen peroxide, can cause the whiteness of bleaching white inadequately, like this when dying light color, vivid look, tend to occur that coloured light is dim, the color and luster atrophy, do not have phenomenons such as gorgeous degree, level-dyeing property difference.Therefore, how solving the difficult problem of fibre and soya bleaching, is to promote the fibre and soya key in application.

Summary of the invention

For addressing the above problem, purpose of the present invention aims to provide that the bleaching whiteness is good, COLOR FASTNESS is good, the dyeing and finishing technology of the soybean fabric lining of good level-dyeing property.

The present invention is achieved through the following technical solutions above-mentioned purpose, a kind of dyeing and finishing technology of soybean fabric lining, comprise bleaching, dyeing, aftertreatment technology, it is characterized in that: described bleaching process comprises under the normal temperature in bath raio is 1: 10 water, the hydrogen peroxide that adds 8 grams per liters, be heated to 70～80 ℃, be incubated 20～30 minutes, add 197 auxiliary agents again, move 5～10 minutes, be heated to 90～100 ℃ then, be incubated 40～60 minutes, wash through washing, pickling, enzyme, dye after cooling to the temperature that dyeing needs.

As to further improvement of the present invention: described bleaching process comprises under the normal temperature in bath raio is 1: 10 water, the hydrogen peroxide that adds 8 grams per liters is heated to 75 ℃, is incubated 20 minutes, add 197 auxiliary agents again, move 6 minutes, be heated to 98 ℃ then, be incubated 50 minutes, through washing, pickling, enzyme is washed, and dyes after cooling to 40 ℃ by the speed of 1.5 ℃/min.

Adopt ED type REACTIVE DYES in the described dyeing, require to carry out the dye ligand ratio according to different color and lusters, add color additive (levelling agent and water softener) again in dye vat, gradation adds glauber salt and soda ash, glauber salt is respectively 30% and 70%, soda ash is respectively 5% and 25%, adds 75% soda ash when being heated to 60～80 ℃ with 1 ℃/min speed, dyes 30～60 minutes, be washed to room temperature then, pickling 1 time 10 minutes is soaped 1～2 time, carries out soft treatment after the color-fixing agent fixation.

Described aftertreatment technology is to adopt loose formula drying machine drying down at 92 ℃, and only cutting open the belly then, water carries out the stentering forming arrangement.

Beneficial effect of the present invention is: 1, bleaching process adopts the high concentration hydrogen peroxide warm to wash vapour to float, and adds the pre-treatment auxiliary agent 197 time-delay oxygen of heating then and floats, and the bleaching whiteness of soybean fabric lining is issued to more than 60% in standard sources; 2, dyeing adopts pre-alkali adding method dyeing, has solved the level-dyeing property problem that color spot and look flower appear in soybean fabric lining dyeing easily, selects new E D REACTIVE DYES for use, makes more than the 3-4 level that the COLOR FASTNESS of lining is up to state standards washing shrinkage≤5%; 4, aftertreatment technology adopts earlier in oven dry below 92 ℃, and the only water stentering forming of cutting open the belly has afterwards guaranteed the washing shrinkage and the soft hand feeling of lining.

The invention will be further described below in conjunction with drawings and Examples.
