What should be noted when selecting felt

         At present, all kinds of felt are divided into special felts and general felts. The difference between the varieties is divided according to the thickness of the raw materials, the size of the unit volume (ie, the tightness of the density) and the difference in color: The technical requirements are divided according to the presence, absence of strength, elongation, and capillary action. The use units can be divided according to needs. Choose it. When inspection, this standard can be used for inspection.

        1. The unit volume weight of the felt (g/cm3) will lose its elasticity if it is too large, and it will lose its wear resistance if the weight per unit volume is too small. The thickness and thickness of the hair have effects on various properties, and the use unit can be properly selected according to the use requirements. It is better to inform the use of the product when purchasing, so as not to affect the production use.

        2. At present, each kind of felt is divided into special felts and general felts. The difference between the varieties is divided according to the thickness of the raw materials, the size of the unit volume (ie, the tightness of the density) and the difference in color: The technical requirements are divided according to the presence, absence of strength, elongation, and capillary action. The use units can be divided according to needs. Choose it. When inspection, this standard can be used for inspection.

       The specifications of the felt type indicate that when ordering the felt, only the item number required by the standard category number is requested, and the specification requirements such as the thickness, the length and the width are provided. If the dyeing is required, the color requirement is also proposed.
