At present, the various kinds of blankets are felt, general felt. Varieties of the difference according to the thickness of raw materials, the size of the unit volume (that is, dense loose density) and color differences to divide: Technical requirements of the difference is according to have, no strength, elongation, capillary action to divide, the use of units can be selected according to needs. Inspection, you can check this standard.
Felt unit volume weight (g/cm 3), too large will lose elasticity, unit volume weight too small and will lose wear resistance. thickness, wool weight and so on a variety of performance has an impact, the use of units can be used according to the use of appropriate selection, procurement is best to inform the use of products, so as not to affect the production use.
