Novel bleaching agent for textile pretreatment

Abstract

The invention discloses a novel bleaching agent for textile pretreatment. The novel bleaching agent is prepared by the following components in parts by weight: 20 to 40 parts of hydrogen peroxide, and 2 to 6 parts of potassium borate; 2 to 5 parts of ethylene diamine tetra sodium; 3 to 5 parts of sodium tripolyphosphate, 10 to 15 parts of acetic acid, 1 to 4 parts of magnesium chloride, 3 to 5 parts of tetraacetylethylenediamine, 2 to 6 parts of sodium silicate, 0.5 to 1.3 parts of sodium hydroxyethyl sulfonate, 10 to 18 parts of sodium percarbonate, 8 to 15 parts of sodium pyrophosphate, 10 to 20 parts of hexamethylenetetramine, and 100 to 120 parts of water. The novel bleaching agent has the advantages that the safety and non-toxic effects are realized, and the bleaching effect is good; at the premise of realizing good bleaching effect, the bleaching temperature is lowered, the damage to a fabric is reduced, the novel bleaching agent is suitable for bleaching the dirt of various fabrics, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a fabric finishing agent, especially a novel bleaching agent used for textile pretreatment. technical background [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 and finishing industry is the "law of reducti...

Problems solved by technology

At the same time, in the traditional hydrogen peroxide bleaching method, it is often necessary to add a hydrogen peroxide stabilizer to control the ineffective decomposition of hydrogen peroxide caused by the catalysis of heavy metal ions.
