RECYCLING IN TEXTILE


RECYCLING IN TEXTILE - Recycling is playing very important role in textile. Textile recycling is the method of reusing or reprocessing used clothing, fibrous material and clothing scraps from the manufacturing process. Textiles in municipal solid waste are found mainly in discarded clothing, although other sources include furniture, carpets, tires, footwear, and nondurable goods such as sheets and towels.
 Textile recycling equipment plays an important part in the textile recycling industry - Standard and high-efficiency textile recycling equipment is quite important for supporting the textile industry.The most popular and widely accepted clothing.


 clothing not only responds to practical needs, fashion has become a form of self-expression and the sheer volume and variety of textile products available on the market have reached unprecedented levels. textiles are not used just for clothes - they are also in our homes, hospitals, workplaces and vehicles, in the form of cleaning materials, leisure equipment and so on. Recovering and recycling textiles provides both environmental and economical benefits by:
  • Reducing the need for landfill space: Certain synthetic fibre products do not decompose, while natural fibre such as wool does decompose but produces methane which contributes to global warming.
  • Reducing pressure on virgin resources. This includes materials traditionally used in textiles such as cotton or wool, as well as oil and other chemicals employed to produce synthetic fibres.
  • Reducing pollution as well as water and energy consumption.
  • Reducing the demand for dyes and fixing agents. This, in turn, lowers the number of problems caused by their use and manufacture.
Textile materials for recycling can be classified either as
  1. post-industrial.
  2. A by-product from yarn and fabric manufacture for the garment-making and retail industry.
  3. As post-consumer, originating from discarded garments, household items, vehicles, etc.
PROCESS
Sorting - collected textiles are manually sorted and graded according to their condition and the types of fibres used. Wearable textiles - Shoes and clothes are resold either in the same country of origin or abroard. Unwearable textiles - These are sold to the 'flocking' industry for shredding and re-spinning.
Re-sorting - Mills-grade incoming material according to their type and colour. The colour sorting means no re-dying is needed, saving energy and avoiding pollutants.  Shredding and pulling - Textile materials are shredded or pulled into fibres. Depending on the end use of the yarn, other fibres may be incorporated. Carding - The blended mixture is carded to clean and mix the fibres. Spinning -The yarn is re-spun ready for later weaving or knitting. 
Textiles made from both natural and man-made fibres can be recycled.
