How to Anti-fouling of Non-woven Fabric

The purpose of easy decontamination finishing is to make the oily liquid dirt on the hydrophobic fiber easy to be removed, and because the liquid dirt is often used as the carrier and binder of the particles, if the liquid dirt is easily washed away, the particles will also be easy to be removed. Remove. The dirt is separated from the surface of the non-woven fabric, except for factors such as washing conditions, which mainly depend on the critical surface tension of the fiber surface, that is, it is related to the surface energy of the nonwoven fabric. The fabric is both easy to decontaminate and resistant to moisture. Performance, it has a high wettability in liquid medium, and has a low interface energy to common oily dirt in air medium, in order to have a good antifouling effect.

Liquid contaminants are primarily contaminated by wetting on the surface of the fibers and then by capillary action into the interior of the fabric, between the fibers and between the yarns. The principle is similar to the wetting and permeation of water on the surface of the fiber, except that the surface tension of the oily liquid is generally smaller than that of water, and therefore, the wettability of the liquid to the nonwoven is strong.
