Waterproof sofa fabrics are not only convenient for daily cleaning, but also play a good protective role in preventing liquid stains from penetrating into the internal structure of the sofa, extending the service life of the sofa. When choosing waterproof sofa fabrics, consumers should consider the environmental performance of the product and choose fabrics treated with non-toxic and harmless environmentally friendly waterproof agents to meet the green and environmentally friendly lifestyle concept. At the same time, the impact of waterproof treatment on the air permeability of the sofa fabric should also be considered to ensure comfort during use.
