Nowadays using renewable textiles rather than fossil-based raw materials has gained great attention in both aspects of the economy and environmentally. Cost of raw material is one of the biggest challenges for manufacturers.
Textile waste recycling is one of the best ways to reduce costs and environmentally harmful impacts. As it decreases the amount of energy consumption on top of reducing raw material costs. Using this method some steps in the process of production like dyeing or scouring would be eliminated.
Some studies have shown that just around 12% of textiles are recycled annually while 90% of them are recyclable. The global market value of recycled textiles has been 5 billion dollars in 2020.
Textile wastes are divided into two groups, pre-consumer waste, and post-consumer waste.
Pre-consumer wastes include those useless fibers, yarn, or fabrics in factories.
post-consumer wastes are those old-fashion or discarded clothes or other household textiles. This category includes most part of textile wastes.
Textile waste recycling is usually done using mechanical or chemical processes.
Mechanical process: The mechanical process is one of the most common ways to invert fabrics to fibers. Then the produced fibers can be spun for either woven or knitted fabric. This way is the best system for the monofilaments and is rarely used for viscose.
Chemical process: This harsh method is included chemicals and enzymes and leads to produce monomers/solvents using depolymerizing/dissolving the fibers.
