Problems solved by technology

But practice has proved that there are serious shortcomings in this system: industrial peracetic acid is usually obtained by the reaction of acetic anhydride (acetic anhydride) and hydrogen peroxide in the presence of sulfuric acid, and its stability is very low, and it has a pungent smell and can burn the skin; more serious Unfortunately, peracetic acid also has the potential to explode, and special containers are required for transportation and storage.
Therefore, although the system has been proposed for a long time, it is still difficult to realize industrial application

Abstract

The present invention discloses process of cold padding, stacking and actively bleaching fabric. The process includes through steps, including one step of compounding bleaching solution and padding, one step of winding and stacking, and one step of hot water washing and cold water washing. The present invention adopts alkanoylxy benzene sulfonate bleaching activator, hydrogen peroxide / activator bleaching system, and cold padding and stacking treatment to reach excellent fabric bleaching effect. Compared with traditional bleaching technology, the present invention has the advantages of excellent fabric bleaching effect, lowered alkali consumption, reduced stacking time, less fabric damage, raised production efficiency and environment friendship.

Description

technical field [0001] The invention relates to a textile bleaching process, in particular to a textile cold pad-batch bleaching method. Background technique [0002] There are three main types of fiber bleaching systems commonly used in the global dyeing and finishing industry: sodium chlorite system, sodium hypochlorite system and H 2 o 2 / NaOH system. Although the chlorine-containing oxidant process can obtain good whiteness and water absorption, it is gradually being used by H due to the disadvantages of large fiber damage and serious environmental pollution. 2 o 2 The bleaching process is superseded. [0003] However, conventional H 2 o 2 / NaOH bleaching must be carried out at a temperature close to the boiling point to have the best effect, which not only consumes a lot of energy, but also easily causes excessive degradation of fibers and serious loss of fabric strength. Especially for fabrics such as wool, hemp, and silk that cannot be processed at high tempera...
