Technical Field

The invention belongs to the technical field of textile after-finishing auxiliaries, and particularly relates to a modified laccase soaping agent for soaping cotton fabrics and a preparation method thereof.

Background

The loose color on the surface of the fabric can be removed through the soaping process after the textile is dyed and printed, and the fastness of the dyed fabric is improved. The soaping agent is added to improve the effect of removing the loose color, and the dye is not adhered to the fabric again through the dispersion, suspension and complexation, thereby achieving the purposes of improving the soaping fastness and preventing staining.

The cotton fabric is also called cotton fabric, and is a fabric woven by using cotton yarn as a raw material. Cotton fabric is one of the most commonly used fabrics with excellent wearability, and is widely used for clothing fabrics, decorative fabrics and industrial fabrics. Cotton is the most popular clothing and home textile fabric. Multifunctional, soft, breathable, moisture-absorbing, comfortable to wear all year round, excellent performance, and durable are just a few of the many qualities that cotton cloth is welcome.

The cotton fabric has strong water absorption, wear resistance, washing resistance, softness, comfort, good warm keeping performance in winter, is breathable and cool in summer, becomes one of the most common children garment materials due to the excellent wearability of the cotton fabric, and is the most popular children garment fabric. But the elasticity is poor, the shrinkage is high, and the fabric is easy to wrinkle. The cotton fabric is generally bright in color and is mainly used for summer wear, casual wear, underwear, sports wear and the like of children.

Laccase is a copper-containing polyphenol oxidase, the only product after reaction is water, and the laccase is essentially an environment-friendly enzyme. The laccase is combined with the anionic dye dissolved or hydrolyzed in water through the cationic active center of the laccase, and the active center of the laccase destroys the chromophoric group of the dye, so that the aim of reducing the color of dyeing residual liquid is fulfilled. Meanwhile, laccase cannot be combined with dyed dyes, so that the color of the cloth cover cannot be influenced. However, when the concentration of the dye in the residual liquid is higher than 5g/L, the decolorization effect of the laccase can be inhibited. Therefore, in the actual production, the concentration of the dyeing residual liquid in the jig dyeing vat is generally higher than 3g/L, the concentration of the dye in the jig dyeing vat is continuously increased, the decolorizing speed of the laccase is lower than the dissolving or hydrolyzing speed of the dye into water, and the decolorizing rate of the dye in the residual liquid is low. Under the condition, the dye which is not damaged can be reversely adhered to the cloth cover, so that the fastness of the finished fabric is reduced, and the single use of the laccase has no practical significance in realizing energy conservation and emission reduction and improving the color fastness of the fabric.

Currently, soaping agent SN is used for high-concentration soaping of reactive dye dyeing and printing. Can be used for boiling, bleaching, dyeing and other functions. Preventing the unfixed dye from re-staining the fiber. The fabric after being washed is soft, has good color fastness, is white as the original anti-staining effect is outstanding, and can obtain excellent effect even if printed cloth such as lake blue, scarlet and the like is soaped, so the fabric is the best product for active soaping at present.

The existing anti-staining soaping agent used for preparing reactive dyes after dyeing is mainly prepared from inorganic salts, polyacrylic acids, organic phosphates, high molecular polymers and surfactants.
