What is the difference between biodegradable fabric and recycled fabric

Recycled polyester fiber, recycled waste Coke bottles as raw materials, PET PET bottles by removing the cap off the label water washing classification crushing flotation and other processing processes, can be made into PET fragments by granulation made of slices CHIP melt drawing and other processing treatment, made of recycled polyester long fiber. Resource re-cycling, recycling is now commonly applied to reduce carbon, green fiber is of great significance to protect the environment and save resources. Renewable fabrics can reduce the consumption of crude oil raw materials to save the energy consumed by crude oil in the manufacturing process of raw silk to reduce the emission of carbon dioxide thus slowing down the rate of global warming to prevent the pollution of soil and atmosphere caused by submergence and burning.


Biodegradable biodegradable yarn: add biodegradable additives in the spinning process to form a new type of spinning stock to make hydrophilic polyester fiber, so that the original moisture is difficult to attach to the surface and structure of the fabric fiber hydrophobic polyester fiber into a new type of polyester fiber material that can be hydrolyzed with microorganisms in nature, redox reaction. When the new biodegradable fiber fabric is buried in the soil, more than 600 kinds of microorganisms in nature will hydrolyze and redox with the polymer of the fiber under the condition of sufficient water, and the biodegradable additives in the fiber will help the microorganisms and bacteria to biodegrade the fiber, and the microorganisms will secrete enzymes to split the molecular chains of PET molecules, so that the polymer will continue to decompose into simpler These simple monomeric components of the basic monomeric structure can be further decomposed by bacteria, leaving carbon dioxide, methane, water and residual biomass in the end.


Renewable fabrics. Recycled fiber, also called rayon, is made by dissolving cellulose such as straw and bark and then spinning it. Although the feel and moisture absorption and breathability of recycled fibers are good, but the processing by chemical processes, so there are bound to be chemical residues, compared with cotton and other natural fibers, environmental performance is poor. Viscose fiber, it is good moisture absorption performance (standard moisture rate of 14%), breathable or more comfortable to wear; in addition, there are some recycled fiber fabrics such as acetate, copper ammonia fiber (standard moisture rate of about 4%), although moisture absorption and breathability is good, but by sweat or wash the strength will be significantly reduced, the strength of the clothing is easy to break. 2. rayon (rayon) sources of oil and Biological, from biological rayon called regenerated fiber, regenerated fiber preparation method: from cellulose raw materials extracted pure alpha-cellulose (called pulp), caustic soda, carbon disulfide treatment, to get orange-colored cellulose sodium xanthate, then dissolved in dilute sodium hydroxide solution, become viscous spinning stock, called viscose.
