PLA Degradable Fiber 1.5D For Medical Nonwoven
1 . Descriptions:
PLA biodegrades slowly in this way - Initially polymer chain of 100,000 to 300,000 molecular weight, break down into its constituent parts (Carbon dioxide and water) within three months in a "controlled composting environment". While compounding polymer if heat of 75C applied at steady rate helps the microbes to decompose in controlled environment. But it will take far longer in a compost bin and in a tightly packed landfill where no light and presence of oxygen are rare available to assist in the process. Indeed, analysts estimate that a bottle grade PLA may take approximate time from 100 to 1,000 years to decompose in soil. Conventional PET polymer contains molecular weight of 170,000 to 350,000 hence it is highly tough to decompose.
We offer the following PLA fibres:
- Solid white PLA fiber, regular,
- Solid dope dyed PLA fiber, regular,
- Solid siliconised PLA fiber, regular,

3. Advantages:
PLA is biodegradable under commercial composting conditions and will breakdown within twelve weeks, making it a more environmentally choice when it comes to plastics in contrast to traditional plastics which could take centuries to decompose and end up creating microplastics.
The manufacturing process for PLA is also more environmentally friendly than that of traditional plastics made from finite fossil resources. According to research, the carbon emissions associated with PLA production are 80% lower than that of traditional plastic
Biopolymer-based composites have attracted the attention of researchers and industries due to their eco-friendliness and environmental sustainability, as well as their suitability for a number of applications. Biocomposites containing natural fibers and biopolymers would be the ideal choice in the development of biodegradable materials for different applications. Polylactic acid (PLA) is an environmentally interesting biopolymer, which also has exclusive qualities, such as good transparency and processability, glossy appearance, and high rigidity, although it has some shortcomings as well, for example, its brittleness and high rate of crystallization.
