What are the materials of biodegradable wet wipes?

2024-12-12

Biodegradable wet wipes refer to wet wipes products that can be naturally degraded and decomposed into harmless substances in a short time under certain conditions. Compared with traditional wet wipes, it has better environmental friendliness and sustainability and is a relatively environmentally friendly product. As consumers pay more attention to environmental issues, the demand for biodegradable wet wipes is also growing. The cleaning market needs more environmentally friendly and sustainable wet wipes products to reduce the negative impact on the environment.

So, what are the common biodegradable wet wipes materials? How should we choose biodegradable wet wipes materials? At present, biodegradable wet wipes are often made of biodegradable materials such as natural cellulose and biodegradable polymers.
Natural cellulose
Natural cellulose (such as bamboo fiber, wood fiber, cotton fiber, etc.) is one of the ideal materials for biodegradable wet wipes, with good biodegradability and natural antibacterial and antibacterial properties.
On the one hand, modern requirements for wet wipes products are not only to be flushable, but also to maintain a certain wet strength. Therefore, the current wet wipes materials generally use short fibers with good flushability and long fibers that can maintain a certain wet strength, and choose different ratios for production. On the other hand, natural cellulose exists in large quantities in nature and has good biocompatibility.
In addition, the microbial communities existing in nature can produce a rich variety of cellulose-degrading enzymes, which can meet the biodegradable needs of wet wipes as raw materials. Wood fiber is the world's largest renewable material resource, and the effective use of wood fiber is of great significance to the sustainable development of society.
In addition, in areas where wood resources are relatively scarce, non-wood plant fibers can be selected as substitutes in the production process of wet wipes, mainly cotton fibers, grass plants, hemp, etc. There are differences in the fiber content of these plant fibers. For example, the fiber content of cotton fibers is close to 100%, which is the highest purity plant fiber; there are many types of hemp fibers, and the more commonly used ones are flax, hemp, ramie, etc., and the content is mostly 60% to 70%. After processing these plant fibers, they can be used as raw materials for wet wipes.
Biodegradable polymers
Biodegradable polymers (such as polylactic acid, polyhydroxyalkanoates, etc.) have good degradation properties and appropriate plasticity. They can degrade rapidly under certain conditions and reduce pollution to the environment. Polylactic acid, also known as polylactide, is a new type of biodegradable material with good degradability. It can be completely degraded by microorganisms in nature and eventually become carbon dioxide and water, which will not pollute the environment. In terms of performance, polylactic acid has good thermal stability and solubility resistance, and can be processed by multiple processing methods such as spinning and extrusion. Products made of polylactic acid as raw materials are not only biodegradable, but also have good antibacterial and heat resistance, so they are widely used.
