As the global awareness of environmental protection continues to increase, biodegradable non-woven fabrics have attracted much attention as a new environmentally friendly material. It not only has the excellent properties of traditional non-woven fabrics, such as lightness, wear resistance, breathability, etc., but also can naturally degrade after use, reducing pollution and pressure on the environment. This article will deeply explore the preparation process, application fields and future development trends of biodegradable non-woven fabrics.
Biodegradable non-woven fabric is a non-woven material made of biodegradable raw materials as the main component. Compared with traditional plastic materials, the raw materials it uses are more environmentally friendly and sustainable, such as bio-based polylactic acid (PLA), starch, etc., which have good biodegradability. Once discarded or lost, biodegradable non-woven fabrics will undergo a period of decomposition in the natural environment, eventually decomposing into harmless water, carbon dioxide and organic matter, with almost no negative impact on the environment.
The process of preparing biodegradable non-woven fabrics usually includes raw material ratio, fiber mixing, spinning and shaping, processing and shaping, etc. In terms of raw material ratio, it is necessary to accurately control the proportion and ratio of different raw materials according to the required performance and degradation speed. During the fiber mixing and spinning process, it is necessary to ensure the uniform mixing of raw materials and the stability of spinning to ensure the quality and performance of the final product. In the processing and shaping stage, appropriate processes and equipment need to be used to process the fibers produced by spinning into calendering, hot pressing and other processes to form the final non-woven product.
Biodegradable non-woven fabrics have broad application prospects in various fields. First of all, in daily life, biodegradable non-woven fabrics can be used in the production of daily necessities, shopping bags, disposable tableware and other products, replacing traditional plastic products and reducing environmental pollution. Secondly, in the agricultural field, biodegradable non-woven fabrics can be used in plant cultivation, soil covering, fruit and vegetable packaging, etc., providing environmentally friendly solutions for agricultural production. In addition, in the medical and health field, biodegradable non-woven fabrics can also be used in the manufacture of medical masks, surgical gowns, medical dressings and other products to ensure the safety and hygiene of medical and health products.
