Plastic bags, once popular, are being gradually replaced because of the people's increasing awareness of environmental protection. An important reason why plastic bags are replaced is that the degradation cycle is too long, while non-woven bags are gradually replaced because of their good degradability. National Bridge Industrial (S.Z.) Co., Ltd. will explain to you what the environmental protection biodegradable nonwoven fabric is.
Biodegradable nonwoven fabric belongs to the direction of non-woven fabric industry. In the domestic concept, "degradable" approximately equal to "dispersible", that is, the overall structure of non-woven fabric can be destroyed within a certain time, but how long can the real natural degradation effect be achieved? In the natural environment, the non-woven fabric can be quickly decomposed and dissipated, and the general degradation cycle is less than 90 days.
Biodegradable nonwoven fabric is actually distinguished not from technology, but from raw materials. At present, mature degradable materials are generally wood pulp (plant fiber) + polyester staple fiber or wood pulp (plant fiber) + viscose. Whether non-woven fabrics can be degraded mainly depends on whether the fibers made of non-woven fabrics can be degraded. General polyester and nylon cannot be degraded, and some polylactic acid fibers can be degraded. With the increase of raw material production capacity, the reduction of raw material price, the progress of technology in many biodegradable non-woven fabric manufacturers and the decline of processing cost, biodegradable nonwoven fabric still has a large market.
