Nonwovens is a non-woven fabric, it is directly applied to polymer chips, short fibers or filaments through the various types of fiber forming methods and condensate into a soft, breathable and flat structure of the new fiber products. It has the characteristics of short process flow, high yield, low cost, quick change of variety and wide source of raw materials. The non-woven fabric is divided into:
The first kind of non-woven fabrics: is the high-pressure micro-jet spray to a layer or dictatorial fiber network, so that each other tangled in the fiber all the way, so that the fiber can be reinforced with a certain strength.
The second type of non-woven fabric refers to the fibrous or powdered hot-melt adhesive reinforcement material in the web, and the web is then heated and heated to a cloth by heating and cooling. The same time as
The first three non-woven fabrics: also known as clean paper, dry paper non-woven fabrics. It is to take the air into the network technology to open the wood pulp fiber board into a single fiber condition, and then use the air way to make the fiber in the network into the curtain, the fiber mesh and then reinforce the cloth. The same time as
The fourth kind of non-woven fabric is that the fiber raw material placed in the water medium is opened into a single fiber, and the fiber is mixed with the fiber material, and the suspension slurry is transported to the netting mechanism. Net and then reinforce into cloth. The same time as
The fifth type of non-woven fabric is that after the polymer has been extruded and stretched to form a continuous filament, the filament is laid into a net, and the web is further adhered by its own bonding, thermal bonding, chemical bonding or mechanical reinforcement , So that the fiber into a non-woven fabric. The same time as
The first six non-woven fabrics: its process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into the network --- reinforced into cloth. The same time as
7 kinds of non-woven fabrics: is a dry non-woven fabric, acupuncture non-woven fabric is the application of puncture needle penetration, the fluffy fiber reinforced into a cloth. The same time as
The 8th nonwoven fabric is a kind of dry nonwoven fabric which is constructed by using a warp-knit coil on a web, a yarn layer, a non-woven material such as a plastic sheet, a plastic thin metal foil, or the like Of the assembly is reinforced to form a nonwoven fabric. Because nonwovens have many functions on the excellent function, extremely versatile.
