Technical Field
The invention relates to a dyeing and polishing process of cloth, in particular to a cloth dyeing and polishing one-bath method based on neutral ferment.
Background
In order to improve the fabric hand feeling of cotton fabrics, the prior cotton fabrics are usually required to be polished before a dyeing process, and the smoothness degree of the fabric surface is improved by an enzyme washing method. However, all the enzymes used in the existing enzyme washing process are acidic enzymes, namely, the pH value of the cloth is adjusted to be acidic by mixing the enzymes and glacial acetic acid; and because the conventional cloth needs to be dyed in a neutral or alkaline environment, the acid enzyme cannot be dyed in one bath with the cloth, so that the polishing process needs to be completed independently before the dyeing of the cotton fabric, and the polishing process generally needs to be completed within 2 hours, thereby reducing the production efficiency of the cotton fabric and increasing the production cost.
Although the method of polishing by using neutral enzyme can reduce the influence of dye on the coloring effect of the fabric compared with acid enzyme, the method can be finished in one bath with the dyeing process of cotton fabrics; however, the polishing effect is relatively poor, and the strong damage of the cotton fabric after polishing cannot achieve the polishing effect of the acid enzyme, so that the process requirement of manufacturers cannot be met. Therefore, the existing cloth polishing process cannot simultaneously have the characteristics of high treatment efficiency and good polishing effect.
