Distinguish from the perspective of environmental protection: Most American dry-laid non-woven fabrics cannot be naturally degraded, but only crack.
Natural degradation and pyrolysis are not the same concepts. Natural degradation means that non-woven fabrics turn into humic plants under natural conditions within a certain period of time, and do not produce harmful substances that have an impact on the environment.
Pyrolysis is the addition of degradable substances during the fiber spinning process. Under the influence of natural conditions within a certain period of time, the fiber products will crack. In fact, the chemical composition of the fiber products has not changed at all, and the environmentally harmful substances remain. Existence, long-term accumulation of damage to soil and water sources will cause irreparable disaster.
