Abstract
The invention discloses a bleach special for soybean protein fiber printing and dyeing pretreatment. The bleach comprises the following ingredients in part by weight: 100 parts of hydrogen peroxide, 50-80 parts of oxygen bleaching stabilizer, 15-20 parts of sodium silicate, 5-10 parts of chelation dispersing agent and 2-10 parts of sodium carbonate, wherein the mass ratio of the sodium carbonate to the sodium carbonate is 1:1. By virtue of the combination of the characteristics of the soybean protein fiber, the formula of the conventional hydrogen peroxide bleach is improved so as to be more suitable for the soybean protein fiber; and moreover the conventional bleaching process is broken, and the specific bleaching process does not need the large bath ratio of the conventional process, so that the stability of the hydrogen peroxide is enhanced, and the bleaching effect to the soybean protein fiber is further improved.
Description
Technical field
The present invention relates to a kind of printing and dyeing pre-treatment bleaching agent, be specifically related to be exclusively used in the bleaching agent of soybean fiber, belong to the whole technology field of seal.
Background technology
Soybean fiber has the good characteristic of natural silk, good hygroscopicity, and ability diluted alkaline, anti-diluted acid, anti-mould, anti-damaging by worms are subjected to pin expense person's welcome at present very much.Soybean fiber is formed through the wet spinning spinning by soybean protein isolate and polyvinyl alcohol mixing solution, and the staple fibre finished product itself is dark yellow, and this has not only brought the outward appearance of practicing white product and has seriously influenced, and has affected the colour brightness of dyeing product.At present, the bleaching process of soybean fiber is still adopted traditional bleaching liquid and bleaching process, thereby, make the development of soybean fiber be subject to obstruction.In addition, the bath raio in the tradition bleaching is excessive, and is very large to the stability influence of bleaching agent, so just more reduced the bleaching effect of soybean fiber.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defective, provides bleaching effect good, and the bleaching process bath raio is low is exclusively used in soybean fiber printing and dyeing pre-treatment bleaching agent;

As the preferred version of such scheme, each component is by weight: 100 parts, hydrogen peroxide, 75 parts of hydrogen peroxide bleaching stabilizers, 16.5 parts of sodium metasilicate, 5 parts of chelated dispersants, 5 parts, sodium carbonate.
Above-mentioned is exclusively used in soybean fiber printing and dyeing pre-treatment with the bleaching process of bleaching agent, comprise the steps,
The preparation of step 1, bleaching liquid
Hydrogen peroxide, hydrogen peroxide bleaching stabilizer, sodium metasilicate, chelated dispersants, sodium carbonate are mixed by recipe ratio be made into bleaching liquid;
Step 2, first is floated
Soybean fiber is bleached for the first time with the bleaching liquid for preparing;
Step 3, first is washed
Will be through soybean fiber that step 2 was floated first after the hot water wash of 70-90 ℃ a time, at once with twice of the cold wash of 0-15 ℃;
Step 4, second is floated
Bleach for the second time with the bleaching liquid that step 1 prepares through the soybean fiber that step 3 was processed;
Step 5, second is washed
The soybean fiber that floated through step 4 is first through the hot water wash of 40-50 ℃ a time, at once with twice of the cold wash of 10-20 ℃;
Step 6, oven dry
At last soybean fiber is dried under 50-60 ℃, be disposed.
In described step 2, step 4, first floats with the second bath raio of floating and is 20:1.
