Pu Coated Fabric Manufacturers introduces 2 advantages of coated fabrics:

 

1. Self-cleaning

An important indicator of coated fabrics is self-cleaning. Just like the surface of the lotus leaf is a regular microstructured surface, the microstructure hides air between the droplets and the coating surface, which has a self-cleaning effect, that is, super protection can prevent the droplets from wetting the surface. Research institutes proposed to use the potential of pulsed UV lasers to perform photon processing on the fiber surface to produce a regular micron-level structure. If modified in a gaseous or liquid active medium, the photon treatment can be carried out simultaneously with hydrophobic or oleophobic finishing. In the presence of perfluoro-4-methyl-2-pentene, the use of radiation can improve the surface roughness of the modified fiber, so that the fiber surface can be combined with appropriate hydrophobic/oleophobic groups to obtain super protective performance. This self-cleaning effect and the characteristics of low maintenance during use have great application potential in high-tech fabrics.

2. Antibacterial function

 

Artificial leather, synthetic leather, or textile coated tents, parasols, awnings, and geotextiles must be resistant to fungi, bacteria, yeast, and seaweed damage. The mode of action of antibacterial agents and microorganisms are interaction with cell membranes, interaction with metabolic process products, or interaction with core materials. Oxidants such as acetaldehyde, halogens, and peroxides can attack the cell membranes of microorganisms or penetrate the cytoplasm to act on their enzymes. As a coagulant, fatty alcohol can irreversibly denature the protein structure in microorganisms. The protonated amino group in chitin can inhibit bacteria by binding to the cell surface of negatively charged bacteria. Other compounds, such as halides, isotriazine peroxides, quaternary ammonium compounds, biguanide, and glucosamine, when applied to textile fibers, will bind to the cell membrane of microorganisms, breaking the oleophobic polysaccharide structure, and finally, Lead to puncture of the cell membrane and cell rupture. The silver compound is used because its complexation can prevent the metabolism of microorganisms.
