Embodiment 1

[0025] Mix 20g of isomeric tridecyl fatty alcohol polyoxyethylene ether (8EO), 5g of diethylene glycol butyl ether and 74g of water evenly, then slowly add 1g of manganese (II) metal complex of acetylacetonate, and add acetic acid under mechanical stirring , adjust the pH to 5-6, and then continue to stir at room temperature for 2-3 hours until a transparent liquid is formed, which is a low-temperature activated bleach.

Embodiment 2

[0027] Mix 20g of isomeric tridecanol fatty alcohol polyoxyethylene ether (9EO), 5g of dipropylene glycol monobutyl ether and 74g of water evenly, then slowly add 1g of cobalt(III) acetylacetonate metal complex, and add acetic acid under mechanical stirring, Adjust the pH to 5-6, and then continue to stir at room temperature for 2-3 hours until a transparent liquid is formed, which is a low-temperature activated bleach.

Embodiment 3

[0029] Mix 20g of isomeric tridecanol fatty alcohol polyoxyethylene ether (9EO) with 5g of diethylene glycol and 74g of water, then slowly add 1g of manganese(III) metal complex acetylacetonate, and add acetic acid under mechanical stirring to adjust the pH 5-6, and then continue to stir at room temperature for 2-3 hours until a transparent liquid is generated, which is a low-temperature activated bleach.

Abstract

The invention relates to a low-temperature activated bleaching agent as well as a preparation method and an application thereof. The low-temperature activated bleaching agent is prepared from the following components by weight percentage: 0.1-1% of acetyl acetone metal complex, 1-10% of organic solvent, 10-20% of fatty alcohol-polyoxyethylene ether, 0.2-1.0% of acetic acid and the balance of water. The preparation method comprises the steps of: uniformly mixing the fatty alcohol-polyoxyethylene ether, the organic solvent and water; then slowly adding acetyl acetone metal complex, adding acetic acid under mechanical agitation, adjusting pH to 5-6, and then continuing to agitate for 2-3 hours at room temperature until a transparent liquid is generated. The invention also provides a batch-type bleaching method of the low-temperature activated bleaching agent for baffeta. The method is simple, low in cost, high in production efficiency, environment-friendly and energy-saving, and suitable for industrial use; and the bleaching temperature is reduced under the precondition of achieving an excellent bleaching effect, and fabric damage is also reduced.

Description

technical field [0001] The invention belongs to the field of bleaching agents, in particular to a low-temperature activated bleaching agent and its preparation method and application. Background technique [0002] At present, from the perspective of the important strategy of my country's economic development, low-carbon economy is running through the entire textile industry as an important way to transform economic development. The innovation of emission technology is the core. Gas emissions, water resource consumption, and energy consumption during the dyeing and finishing process of textiles are the most fundamental basis for the industry's final comprehensive assessment of product environmental impact. At present, there are already some mandatory or voluntary regulations or market restrictions in the world, such as requiring information such as product labeling carbon footprint. Therefore, one of the basic principles for the sustainable development of the entire dyeing a...
