Abstract
The invention relates to a low-temperature activating and bleaching method by using water-soluble metalloporphyrin, belonging to the field of low-temperature activating and bleaching method. The method comprises the following steps: (1) mixing the water-soluble metalloporphyrin, H2O2, a penetrant and a stabilizer to obtain a bleaching work liquid; (2) padding textiles in the bleaching work liquid; and (3) carrying out cold batching or steaming on the padded textiles, and then washing with water. The method is simple, has the advantages of low cost, high production efficiency, environmental friendliness and energy saving and is suitable for industrialized use. Besides, the method lowers the bleaching temperature, shortens the batching time and reduces damage to textiles on the premise of achieving a fine bleaching effect.
Description
Technical field
The invention belongs to the method field of low-temperature activated bleaching, particularly relate to a kind of method of using the low-temperature activated bleaching of water-soluble metal porphyrin.
Background technology
Hydrogen peroxide bleaching is an important process in the textiles pre-treatment, and the whiteness height of BLEACHED FABRIC, not yellowing, environmental pollution are little, therefore is widely used in the pre-treatment bleaching process of various fabrics.
Conventional hydrogen peroxide bleaching comprises: high-temperature bleaching and the bleaching of cold rolling heap.
1) technological process of high-temperature bleaching is: pad bleaching liquor → decatize → washing → oven dry.
Bleaching liquid contains hydrogen peroxide (100%) 2～15g/L, regulates pH value to 10.5～11 with caustic soda, and adding stabilizing agent and wetting agent are an amount of, pad bleaching liquor when room temperature, and 95 ℃～100 ℃ decatize 45min～60min wash out cloth then.
Shortcomings such as the shortcoming that high-temperature bleaching technology exists: process energy consumption height, fiber strength reduce greatly, and processing back fabric feeling is coarse.
2) technological process of conventional cold rolling heap bleaching is: the alkali consumption is 50～60g/L, H
2O
2(100%) be 18～20g/L, 24h banks up.
The shortcoming of conventional cold rolling heap bleaching: technological temperature is low, the dense height of alkali, the infiltration difficulty, and the present cold-pad-batch preparation time, about 24h, production efficiency was lower mostly.
At present the hydrogen peroxide activator system of research and development mainly comprises: assorted how structure compounds of alkanoyl compounds, amide groups compounds, oxidation and organo-manganese compound etc.The product of industrialization mainly is tetra acetyl ethylene diamine (TAED) and pelargonyl group benzene sulfonic acid sodium salt (NOBS) on the market; this two compounds has obtained using widely in American-European Betengent product; but not very ripe all the time in the application in the textile bleaching pre-treatment, also exist a lot of defectives.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method of using the low-temperature activated bleaching of water-soluble metal porphyrin, and this method is simple, and cost is low, the production efficiency height, and environmental protection and energy saving are suitable for industrialization and use; Reaching under the prerequisite of good bleaching effect, reducing bleaching temperature, shortening and bank up the time, reducing fabric damage.
