Embodiment 1

[0070] Soaping fabric: pure cotton woven fabric (25tex×25 tex 140×100) dyed with reactive turquoise blue KN-R, the K / S average value before soaping is 8.2.

[0071] Continuous low-temperature soaping process: dyed fabric → first compartment washing (30°C) → second compartment soaping with metal complex oxidation system (N,N',N"-tris[salicylideneaminoethyl]amine ) Copper complex 5μmol / L, sodium percarbonate 2g / L, add separately when used, 50°C) → wash with cold water in the third tank (30°C) → discharge the cloth.

[0072] Continuous conventional soaping process: Dyeing fabric → cold water washing in the first compartment (30°C) → hot water washing in the second compartment (90°C) → soaping in the third compartment (soaping agent 1g / L, 95°C) → Wash in hot water (90°C) in the fourth compartment → wash in cold water (30°C) in the fifth compartment → fabric out.

Abstract

The invention relates to a metal complex oxidation system and an application thereof. The metal complex oxidation system comprises metal complex and peroxide. The metal complex oxidation system is used for soaping the dyed textiles, and the soaping temperature is between 20 and 80 DEG C. The metal complex oxidation system is simple in operation of a low-temperature soaping method, is low in production cost, has a good soaping effect and is suitable for various dyes; and the anti-color staining capability is strong, the textile damage is small, energy and water consumption is saved, the decolorization ratio to soaping residual liquid is above 90%, and the chemical oxygen demand (COD) and chromaticity of dyeing soaping wastewater can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of soaping agent for soaping after dyeing of textiles, in particular to a metal complex oxidation system and application thereof. Background technique [0002] After the fabric is dyed, in order to improve its color fastness and brightness, detergent must be used to remove a small amount of unfixed dye on the fiber, otherwise it will seriously affect the color fastness of the textile, making these fabrics in the process of wearing and using Color fades a lot and will stain other clothing as well. Soaping agents on the market have a temperature as high as 98-100°C during soaping. This condition consumes energy and water, which is not conducive to energy saving and consumption reduction. [0003] The earliest US patent US4902439 introduced a reactive dye soaping composition, which included aluminum silicate, trihydric alcohols, anionic surfactants and nonionic surfactants, and US patent US5378242 introduced a soaping ...
