Abstract

The invention discloses waterproof cotton cloth with good antibacterial properties and a preparation method thereof. The waterproof cotton cloth comprises the following raw materials by weight: 16-23parts of degreased cotton cloth, 4.6-7.2 parts of tourmaline powder, 2.4-3.9 parts of cellulose, 3-4.2 parts of negative ion powder, 6-8.8 parts of Artemisia argyi, 4-5.8 parts of polyvinyl alcohol, 3-4.5 parts of tartaric acid, 2.6-4.2 parts of sodium laureth sulfate and 4-6.6 parts of chitosan. According to the invention, the raw materials of the invention are widely available; different products are obtained by employing different processes for different raw materials; the degreased cotton cloth is immersed in a mixture of different products and subjected to a reaction and drying successively, so a prepared product has good gas permeability and antibacterial properties and can meet the usage needs of shopping bags.

Description

technical field [0001] The invention relates to a cotton cloth, in particular to a waterproof cotton cloth with good antibacterial performance. Background technique [0002] With the reduction of resources and the enhancement of people's awareness of environmental protection, more and more people use environmentally friendly cloth bags for shopping. Cotton bags are a common kind of environmentally friendly cloth bags. Cotton bag is an environmentally friendly cloth bag, which is small, convenient, durable, and does not pollute the environment. The biggest advantage is that it can be reused, thereby reducing environmental pollution to a greater extent. Cotton bags are very environmentally friendly in terms of raw materials; moreover, because the price of cotton bags is higher than that of non-woven fabrics, companies and units that choose them generally pay more attention to environmental protection and are more powerful, and they will not save money on ink. It is a bit ex...
