What are the characteristics of GRS felt?

Author:


  GRS Feltmade of wool, bonded by processing (no interweaving of warp and weft). The main features are as follows:

1. It has elasticity and can be used as a material for shockproof, sealing, gasket, and elastic steel wire needle cloth-based felt.

2. Good adhesion, not easy to loosen, can be die-cut into parts of various shapes.

3. Good thermal insulation performance, can be used as thermal insulation material.

4. Compact structure, small pores, can be used as a good filter material. The felt has low density and stable performance, and can produce various felt parts by stamping.

5. It has good wear resistance and can be used as polishing material.

6. Elastic, so bonded by the principle of felting. Bonded flannel can be used according to density and specifications.

7.GRS felt has good stretchability and can reach the specified length. It can be used for leather calendering belt and pulp suction belt in papermaking.

8.GRS felt has good heat insulation and can be made into standard felt insoles.

9.GRS felt moisture and elasticity, can be made into automobile door and window sealing strip and central door and window sealing strip. It is not woven, so it has good filterability and can be used to absorb oil. GRS felt is mainly used under the oil drums of ships to keep them clean. The machine parts packed with GRS felt have high whiteness, good impact resistance and noise reduction performance.

Factors affecting the elasticity of GRS felt:

The elasticity of GRS felt is determined by the density of the felt. If the density is too high, the elasticity will become smaller; on the contrary, if the density is too low, the toughness and resilience will be lost. Such as other thickness, wool thickness and quality. These have an impact on the performance, the user can use the appropriate choice according to the requirements.

GRS felt manufacturers said: As a solar material, the advantage of felt is that it can not only block part of the sunlight, reduce the temperature of the cloth, but also change the transmitted light from direct to scattered, so that the covered crops are evenly exposed to light and the transmission light utilization rate is high. Felt moisture-proof, breathable, flexible, light, non-combustion, easy to decompose, non-toxic, non-stimulating, colorful, low price, recyclable. For example, polypropylene (PP) particles are mostly used as a raw material and are produced by a continuous one-step process of high temperature melting, spinning, wire laying, hot pressing and winding.

GRS felt is a dry non-woven fabric, also called needle felt, is made of polyester and polypropylene raw materials, after repeated needling and proper hot rolling. The staple fibers are opened, carded and spread into a web, which is then reinforced into a cloth by needling. The barbed needle has a hook. The fiber web is repeatedly pierced, the hook tape fibers are reinforced, and a needle felt is formed. There is no difference between felt warp and felt weft. The fabric is disorganized, with little difference in warp and weft performance. Wool itself is also a biodegradable, non-toxic and environmentally friendly material. GRS felt can be used as shockproof, sealing, gasket and elastic steel wire clothing felt, with good adhesion, not easy to loosen, and can be cut into parts of various shapes.
