What are the characteristics of bio-based chemical fibers?
Bio-based chemical fibers have always been considered as "green fibers", "ecological fibers" and "environmentally friendly fibers". So what are the characteristics of bio-based chemical fibers?
First of all, raw materials are by-products of plants and animals, which are renewable and can achieve sustainable development.
Secondly, bio-based chemical fibers have a low carbon footprint: all or part of the carbon atoms contained in bio-based chemical fibers are derived from biomass. Taking plant biomass as an example, plants absorb CO2 in the earth's atmosphere during the production process and use photosynthesis to synthesize new carbon-containing natural macromolecules. After it is discarded, whether it is biodegraded in the environment or burned into CO2, no additional carbon emissions will be produced from the perspective of the entire life cycle. Therefore, bio-based chemical fibers have the characteristics of overall carbon emission reduction or no carbon emission increase.
Thirdly, most bio-based chemical fibers can show excellent biodegradability and biocompatibility: depending on the specific chemical structure, some bio-based chemical fibers can degrade in compost, the natural environment and living organisms, and have good biodegradability. Biocompatibility, can be used in biomedical and other fields.
