Early Nonwoven Fabric Production Process - Impregnation Method

Impregnation method is one of the earliest production methods of Nonwoven Fabric materials, and most of the early Non Woven Fabric products are produced by this method. At present, some low - grade and low - priced products are still produced by this method, such as various finger cloths in disposable materials, bag lining adhesive village base cloth, packaging materials, agricultural insulation materials, etc.

With the continuous improvement of the production process of the impregnation method and the advent of new varieties such as adhesives and various auxiliaries, the impregnation method Non Woven Fabric Roll products have broadened the application field. For example, the wiping cloth with viscose fiber or cotton as raw material uses acrylate, vinyl acetate and its copolymer as binder, and its weight is about 4 gm; agricultural insulation materials mostly use lighter weight, about 30 g / m2. It is used to cover the surface of farmland after the seeds are sown to reduce the temperature difference at night and resist the attack of sudden cooling weather on the seed buds. This product has good air permeability and moderate strength. It can be reused and the cost is low.
