The felt is mainly made of wool processing and bonding, and the wear resistance and breaking strength of the felt are very important for its use effect.
Generally, the wear resistance test of felt is carried out on the fabric friction strength machine, and the needle of the fabric friction strength machine must first be set to the zero position. Then clamp the felt sample smoothly and in a tense state. The breaking strength test of the felt is carried out on the fabric strength machine. Under certain environmental conditions, the samples are clamped in the jaws of the upper and lower grippers of the strength machine one by one. Pay attention to the break of each sample. The strength is averaged arithmetic, and the average value is the breaking strength of the felt.
Generally speaking, the felt has good adhesion performance and is not easy to loosen. It can be punched into various shapes of parts; it has good thermal insulation performance and can be used as a thermal insulation material.
