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, the raw materials are by-products of plants and animals, which are renewable and can achieve sustainable development.
Second, bio-based chemical fibers have a lower 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 generation process and use photosynthesis to synthesize new carbon-containing natural macromolecules.
Whether it is biodegraded in the environment or burned to carbon dioxide after it is discarded, no additional carbon emissions will be generated from the perspective of the whole life cycle. Therefore, bio-based chemical fibers have the characteristics of overall carbon reduction or no carbon increase.
Thirdly, most bio-based chemical fibers can exhibit excellent biodegradability and biocompatibility: depending on the specific chemical structure, some bio-based chemical fibers can be degraded in compost, natural environment and in vivo, and have good Biocompatibility, can be used in biomedical and other fields.
