Problems solved by technology

At present, there have been attempts at low-temperature processes in dyeing and finishing innovations, such as: low-temperature cold pad-batch pretreatment and bleaching processes for cotton fabrics. In the absence of low-temperature oxidation activators, conventional hydrogen peroxide/NaOH systems are used for low-temperature bleaching. When bleac

Abstract

The invention relates to a low-temperature scouring and bleaching promoter composition and a preparation method thereof. The composition comprises 2.5-5.5% of Tetra acetyl ethylene diamine (TAED), 0-0.5% of hydrogen peroxide decomposition catalyst, 5-15% of bleaching potentiator, 10-15% of chelating agent, 77-54.5% of carrier and 5-10% of surfactant, according to the weight percentage. The preparation method comprises the steps as follows: the carrier, the TAED, the hydrogen peroxide decomposition catalyst, the chelating agent and the bleaching potentiator are sequentially added in a powder mixer and mixed uniformly for 45-60min; subsequently, the surfactant is added and all mixtures are mixed for 15-30min and then discharged, thus obtaining the composition. The low-temperature scouring and bleaching promoter composition belongs to the environment-protective promoter composition, contains no phosphor and other substances harmful to the environmental protection, has no AOX problem, achieves the object that one promoter replaces more than four promoters, and facilitates processing and quality control.

Description

technical field [0001] The invention belongs to the field of environment-friendly low-temperature scouring and bleaching auxiliaries and the preparation thereof, and in particular relates to a low-temperature scouring and bleaching auxiliaries composition and a preparation method thereof. Background technique [0002] Cotton knitted fabrics are composed of cotton fibers. Cotton fiber contains 0.4-1.2% pectin, 0.4-1.2% oil wax, 1.0-1.9% nitrogen-containing substances, 0.7-1.6% ash and a small amount of pigment and other natural impurities (called cotton fiber symbionts), and cottonseed hulls (called companions). Symbiosis mainly exists in the cuticle and primary rubber wall of cotton fiber. Their existence makes cotton fiber hydrophobic, affects water absorption, and hinders the penetration and diffusion of dyes in the dyeing process. Cotton seed hulls affect the appearance of fabrics. Therefore, the symbiotic and accompanying organisms must be removed in the dyeing and ble...
