Preparation method of dyeing prevention agent

Abstract

The invention discloses a preparation method of a dyeing prevention agent. The preparation method comprises the following steps: adding 57 to 59 parts of water into a reaction kettle; heating to 70 to90 DEG C; meanwhile, rotating stirring blades in the reaction kettle; slowly adding 14 to 16 parts of polyester type dyeing prevention powder under the state that the stirring blades rotate and at the rotary speed of 20 to 40r; after the powder is completely dissolved, closing a heating device; slowly adding 14 to 16 parts of fatty alcohol type surfactant and 11 to 13 parts of polyamine type color fixing agent until the components are uniformly stirred; standing and cooling; discharging into a packaging bucket and conveying into a factory for direct utilization. The preparation method of thedyeing prevention agent has the advantages of ingenious technology and simple technological steps and is suitable for being popularized.

Description

technical field [0001] The invention relates to the technical field of anti-staining agents, in particular to a preparation method of anti-staining agents. Background technique [0002] Because the jeans are easy to decolorize during the washing process, the dye in the water will stick to the surface of the jeans again to form a floating color, which makes the surface of the jeans unclear, and the white yarn of the monkey bit and the white pocket cloth are stained blue. color or other colors, so people invented the product of anti-staining agent. There are generally two ways to solve the problem of anti-dyeing: complexing free indigo dyes, and dispersing dye molecules in water to keep them free in water. There are two commonly used products; polyester anti-dyeing powder (abbreviated as: PGT) and fatty alcohol surfactant (O-80 or thirteen isomers). [0003] Existing technical schemes include: 1. In the whole denim garment washing process, desizing (water temperature 50 degr...

Problems solved by technology

However, since the polyester anti-dyeing powder is difficult to dissolve in cold water, and cannot quickly exert its effect, the anti-dyeing effect cannot be achieved

At present, the competition in the clothing market is becoming more and more fierce. The quality of clothing fabrics is even worse, the color fastness is lower, and it is easier to break. Jeans lose or break, causing huge losses.
