Problems solved by technology

However, in the prior art, there are very few coated cloths that simultaneously realize waterproof and antibacterial effects, and the addition of waterproof and antibacterial materials often makes the softness and mechanical properties of the coated cloth worse, affecting the normal use of the coated cloth, and , the general waterproof and antibacterial materials have limited adhesion on the base fabric and cannot be used for a long time
In addition, how to achieve uniform coating of waterproof materials and antibacterial materials is also a big problem

Abstract

The invention discloses a waterproof antibacterial coating fabric and a preparation technology thereof. The coating fabric comprises a base fabric and a waterproof antibacterial layer sequentially coating the surface of the base fabric. The waterproof antibacterial layer is prepared from, by weight, 50-65 parts of bamboo fiber, 15-25 parts of wasabi, 15-30 parts of wax gourd, 40-55 parts of a polyvinylidene chloride emulsion, 35-45 parts of acrylate copolymer and paraffin compound emulsion, and 10-15 parts of sodium carboxymethylcellulose. The coating fabric achieves the waterproof and antibacterial performance at the same time, the flexibility and mechanical property of the coating fabric are good, the waterproof antibacterial layer uniformly coats the base fabric, the attaching firmness is good, the coating fabric can be still well attached after being used for a long time, and the coating fabric has the long service life.

Description

technical field [0001] The invention relates to a coated cloth, in particular to a waterproof and antibacterial coated cloth and a preparation process thereof. It belongs to the technical field of textile materials. Background technique [0002] Coated cloth is mainly coated with a layer of material with special functions on the basis of cloth, which adds special functions to the cloth. Coated cloth is widely used in tents, clothing, bags, national defense, transportation and many other fields. Coated cloth will inevitably come into contact with a high humidity environment during use or storage. At this time, waterproof and antibacterial properties are particularly important. [0003] Under normal circumstances, the method of coating with waterproof materials can be used to achieve waterproofing, and the method of adding antibacterial materials can achieve better antibacterial effect. However, in the prior art, there are very few coated cloths that simultaneously realize w...
