How is the decomposition of biodegradable non-woven fabric carried out?

The decomposition of biodegradable non-woven fabrics is a highly concerned topic, which involves the lifecycle management of environmentally friendly materials and important methods for reducing plastic pollution. With the increasing attention to environmental issues, we urgently need to understand the decomposition process of biodegradable non-woven fabrics in order to better utilize these materials and reduce their adverse effects on the environment. This article will delve into the decomposition mechanism, influencing factors, and environmental significance of biodegradable non-woven fabrics.

How is the decomposition of biodegradable non-woven fabric carried out

 Biodegradable materials:

Biodegradable non-woven fabrics are usually made of biodegradable materials such as starch, polylactic acid (PLA), polyhydroxyalkanoates (PHA), etc. These materials can be degraded by microorganisms in natural environments. The decomposition process begins with microorganisms adsorbing onto the surface of non-woven fabric and then secreting enzymes to break down polymer chains.

Natural decomposition rate:

The natural decomposition rate of biodegradable non-woven fabrics depends on multiple factors, including material type, environmental conditions (such as temperature, humidity, and oxygen levels), microbial activity, and so on. Usually, warm and humid environments help accelerate decomposition, while dry and cold environments slow down the decomposition rate. Under ideal conditions, biodegradable materials can completely degrade within a few months to years.

Photodecomposition:

Photolysis is a process of decomposing biodegradable non-woven fabrics, in which ultraviolet light can break down the molecular bonds in the material into smaller fragments. This process usually requires exposure to sunlight outdoors, and different types of biodegradable non-woven fabrics have varying degrees of sensitivity to photolysis.

Wet degradation:

Some biodegradable non-woven fabrics decompose in humid environments. Wet degradation is usually accelerated by the action of water molecules. Water can penetrate into the interior of materials, breaking down molecular bonds, making them fragile and ultimately breaking down into smaller fragments.

Microbial degradation:

Microorganisms play a crucial role in the decomposition process of biodegradable non-woven fabrics. They decompose organic matter in materials and convert it into simpler substances such as carbon dioxide, water, and organic waste. This process usually occurs in soil, compost piles, and natural water bodies, requiring appropriate temperature, humidity, and microbial activity.

Decomposition products:

The final substances produced by the decomposition of biodegradable non-woven fabrics include water, carbon dioxide, and residual organic matter. These products usually do not cause pollution or harm to the environment.

The decomposition of biodegradable non-woven fabrics is an important aspect of environmental protection and sustainable development. By gaining a deeper understanding of the decomposition mechanism and influencing factors, we can better manage and utilize these materials, reduce plastic pollution, and decrease dependence on harmful plastic waste. Through continuous scientific research and environmental education, we can work together to promote more environmentally friendly and sustainable material choices, and contribute to the future of the earth. I hope this article can inspire more research and discussion on the decomposition of biodegradable non-woven fabrics.

Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
