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 relates to a processing method of multifunctional coated fabric with hydrophobic and antibacterial functions. The processing method of the multifunctional coated fabric with hydrophobicand antibacterial functions comprises the steps as follows: 1) raw materials of an antibacterial coating are mixed and then stirred for 12-24 h, antibacterial coating slurry is obtained and uniformlyapplied to the surface of warp knit fabric, the warp knitted fabric is dried, and an antibacterial coating is formed on the surface of warp knitted fabric; b) raw materials except hydrophobic nanofiber for producing a hydrophobic coating are mixed and stirred at 50-80 DEG C for 1-3 h, and hydrophobic coating slurry is obtained, the stirred hydrophobic coating slurry is uniformly applied to the antibacterial coating obtained in step a, and warp knitted fabric with the hydrophobic coating is obtained; c) the hydrophobic nanofiber is planted on the surface of the hydrophobic coating obtained in step b with an electrostatic flocking method and the multifunctional coated fabric with hydrophobic and antibacterial functions is prepared.

Description

technical field [0001] The invention relates to a coated cloth, in particular to a method for processing a hydrophobic and antibacterial multifunctional coated cloth. 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 waterproof and antibacterial effects, and the addit...
