Non-woven fabrics are characterized by being moisture-proof and breathable. They are used in various industries, such as sound insulation, heat insulation masks, etc. It is a plant formed without spinning and production. It is produced through mechanical methods, and there are many factors that affect the adhesion of customized non-woven fabric. Let's take a closer look together!
1. Wet wet
Wet wetness of non-woven fabric causes gaps between the molecular seams to make the glue evenly distributed on the surface. Generally speaking, the contact angle can be used to represent the degree of wetting of liquid on a solid surface, which can be used as a liquid as a liquid. Drip, solid, and gas contact three-phase interface. It can be seen that the smaller the contact angle, the better the non-woven wetting.
2. Diffusion of adhesive action
Non-woven adhesives require a certain spreading performance. Through the diffusion effect, the adhesive molecules and some fragments can pass through the interface to the diffusion interface area, complete wetting, and spreading, etc., and it is useful for the closure of adhesive molecules and adhesive materials. If the distance is less than 0.5 nanometers, molecular attractions or combinations of molecules that are conducive to binding can be generated.
3. Mechanical adhesion
Non-woven mechanical adhesion refers to the penetration of the adhesive into the pores or surface of the adhesive material, and the adhesive material is bound by an anchor hook or a solid adhesive.
The above factors affect the adhesion of non-woven fabrics. The following references can be made when using The application is now becoming more widespread, breaking the traditional textile principle, and has the characteristics of short process, high output, and low cost.
