Description
Technical Field
The invention belongs to the technical field of textiles, and relates to a biological compound for improving the wool effect of a fabric, and a preparation method and application thereof.
Background
The textile pretreatment process aims to remove impurities such as waxy substances, pectin substances, polysaccharides, organic acids, nitrogen-containing substances, ash and the like contained in pulp and textile cellulose, and obtain good water absorption and certain whiteness, so as to be beneficial to dyeing and finishing. In continuous dyeing or printing, the fabric is padded with a dye liquor (or printing paste) and the dyeing (or printing) process can be completed within only a few seconds, and the wool effect is one of important indexes for evaluating the scouring effect of semi-finished products and whether dyeing or printing can be performed.
The traditional textile pretreatment process generally adopts caustic soda high-temperature refining to remove non-fiber components on the surface of the fabric, such as: slurry, wax and cottonseed hulls. However, excessive caustic soda consumption easily causes fiber damage, and reduces the toughness and strength of the fabric; when the amount of the caustic soda is insufficient, the removal effect of wax and cottonseed hulls is reduced, the wettability, namely capillary effect, of the fabric is influenced, the subsequent dyeing and printing quality is further influenced, and the quality of the fabric is reduced. And the alkali scouring method generates a large amount of wastewater with strong alkalinity and high COD, and cannot adapt to the trend of green textile development at home and abroad.
The application of the method for treating the biological enzyme before dyeing can save the cost of water and wastewater treatment, reduce the environmental pollution and improve the quality of products. However, the effect of only using biological enzyme to compound and treat the fabric has some defects, and the content and the components of the sizing agent on different fabrics are variable and basically contain starch sizing agent, PVA sizing agent and wax. The quality of desizing and wax removing effects directly influences the wool effect of the fabric, and the key for improving the wool effect of the fabric is how to improve the desizing rate and effectively remove wax.
CN106758263B discloses a method for preparing a cotton product easy to decontaminate by a biological method, in the method, laccase, lipase and acetalase are compounded to achieve the effect of removing oil stains on fabrics, and the application is a decontamination finishing agent and does not relate to desizing and dewaxing effects. CN105970633B discloses a biological compound for textile, in said method utilizing auxiliary combination of several enzymes to attain the high-effective desizing effect, and has no need of decomposing or removing wax component, however the existence of wax also is an important factor for influencing fabric wettability, i.e. capillary effect.
In the field, the desizing effect and the capillary effect of the fabric after the textile pretreatment are further improved, the quality of the subsequent dyeing and printing process is improved, the dosage of the subsequent additives is reduced, and the cost is reduced. There is a need to develop a biocomposite that is more effective in increasing the wool efficiency of fabrics.
