Method for improving yellowing resistance of antibacterial ultraviolet-proof composite curtain fabric

Abstract

The invention discloses a method for improving the yellowing resistance of an antibacterial and ultraviolet-proof composite curtain fabric. The method comprises the following steps: S1, selecting base cloth and performing pretreatment; s2, performing color scraping surface waterproof treatment on the color scraping surface of the base cloth; s3, preparing antibacterial and ultraviolet-proof color paste, blade-coating the color scraping surface of the base cloth with the antibacterial and ultraviolet-proof color paste, and then sequentially performing drying treatment and calendaring treatment on the color scraping surface; s4, bonding a PE film to the composite surface of the base cloth; s5, carrying out rolling and curing treatment on the compounded fabric to obtain a finished product of the antibacterial and ultraviolet-proof type composite curtain fabric. On the premise of ensuring that the composite curtain fabric has antibacterial and ultraviolet-proof properties, the yellowing resistance of the fabric is improved, the use requirement standard of customers is met, and the processing cost and the popularization difficulty of products are reduced.

Description

technical field [0001] The invention relates to the technical field of composite curtain fabrics, in particular to a method for improving the anti-yellowing performance of antibacterial and anti-ultraviolet composite curtain fabrics. Background technique [0002] There are many types of fabrics according to different materials and usage requirements, and they cover a wide range of usage scenarios. Some are made into clothing, some are made into sheets and quilts, some are made into coverings such as tablecloths and carpets, and some are made into curtains as mentioned in this article. [0003] However, fabrics have so many use scene functions, which are not inherently possessed after the raw materials are woven into cloth. According to different usage requirements and usage scenarios, fabric craft manufacturers in different fields need to further process it. [0004] For example, curtain fabrics are not suitable for ordinary fabrics in other fields, especially for special ...

Problems solved by technology

[0006] However, the antibacterial finishing agents used in the existing composite curtain fabrics on the market are mainly silver ions. Although it has a good antibacterial effect, its stability is relatively poor, and it is prone to yellowing and staining when it is irradiated by sunlight or ultraviolet rays and stored. The problem of precipitation (dissolution of silver ions is not good for human health), and it is also easy to cause redox reactions with moisture and oxygen in the air to cause problems such as darkening and blackening of the color. In addition, the high processing cost has made it difficult to widely promote and apply

[0007] Therefore, how to solve the problem that composite curtain fabrics are prone to yellowing under the premise of ensuring antibacterial and anti-ultraviolet properties is a technical problem that plagues those skilled in the art
