Study On-Recycling of textile waste products on different process.
Presentation on -garments waste product re-use. Recycling is a process in which waste materials are treated in a way that they can be used again. Processes Of Recycling : Collection The first step required for recycling is collecting recyclable materials from communities. Families who recycle items such as paper, bottles and cans, place the items in recycling collection bins. These bins usually have the recycling symbol on them.

2. WHATIS TEXTILERECYCLING?
Textile recycling is the process by which old clothing and
other textiles are recovered for reuse or material recovery. It
is the basis for the textile recycling industry.
3. Textile wastes can be classified into two categories:
1. Pre-consumer (Production):
• Waste originates from manufacturing of textiles products.
• Textile off cuts from garmenting section
2. Defective rolls of fabric or leather items Post-Consumer:
• Waste originates from consumers
• Worn out textiles goods
Textile wastes categories………..
4. It is a surprising fact that over 70 percent of the world’s population uses second
hand clothing.
Raw materials acquired out of recycled fabrics cost less; making it an attractive
feature for manufacturers.
Percentage usage of discarded textiles……
Of all the old clothing,
70 % is used as second hand clothing,
6 % is waste bags and zips,
8 % is used for reclaiming fibers and making
recycled products,
7 % is used as wiping material and the
remaining 9 % is shredded and used as
stuffing.
5. Traditional sources of textile waste come from three different sources:
Fiber , yarn and fabric processing.
Sewn products manufacture.
Disc textile and cutting waste at the manufacturing level are consider pre-consumer waste.
8. The recycling process of natural
fibers……
For textile to be recycle, there are fundamental difference between natural and synthetic fiber.
For Natural Textiles:
The incoming unwearable material is sorted by type of material and color
Textiles are then pulled into fibers or shredded
The yarn is then cleaned and mixed through a carding process
Then the yarn is re-spun and ready for subsequent use in weaving or knitting
Then the yarn in re-spun and ready for subsequent use in weaving or knitting
9. Cotton fabric Process…………
cotton can be Process recycle from pre-consumer (post-industrial) and post-consumer cotton waste.
Pre-consumer waste comes from any excess material produced during the production of yarn, fabrics
and textile products, e.g. selvage from weaving and fabric from factory cutting rooms.
Post-consumer waste comes from discarded textile products, e.g. used apparel and home textiles.
During the recycling process, the cotton waste is first sorted by type and color and then processed
through stripping machines that first breaks the yarns and fabric into smaller pieces before pulling
them apart into fiber. The mix is carded several times in order to clean and mix the fibers before they
are spun into new yarns.[
The resulting staple fiber is of shorter length compared to the original fiber length, meaning it is more
difficult to spin. Recycled cotton is therefore often blended with virgin cotton fibers to improve yarn
strengths. Commonly, not more than 30% recycled cotton content is used in the finished yarn or
fabric.
Because waste cotton is often already dyed, re-dyeing may not be necessary. Cotton is an extremely
resource-intense crop in terms of water, pesticides and insecticides. This means that using recycled
cotton can lead to significant savings of natural resources and reduce pollution from
agriculture. Recycling one tone of cotton can save 765 cubic meters (202,000 US gal) of water.
10. Denim recycling project…….
• Cotton is sensitive to plagues and deceases
• Therefore a lot of chemicals are used
• Growing cotton requires a lot of water
• Cotton grows on valuable soil that is also fit for food.
11. Recycling denim project with G-
Star Process …….
Collecting, recovering fibers, fabric production, garment production G‐Star, a major
international denim brand decided to work with us and introduces a small collection in
which 10% of the total product consists of recovered cotton fibers, thus creating 10%
of the results mentioned above. Further development is now focused on raising the
percentage of recycled fibers by the production of a higher quality of fibers in the
recycling process.
12. Benefits of Recycling…….
Financial Benefits
Conservation of Resources
Energy saving
Community Building
Jobs creation
Strong economy
Environmental Protection
16. Build a strong Economy………..
Lower waste management costs
Cheaper production materials
Energy saving
Jobs creation
17. Protect the environment………
Reduced contamination risk from landfills
Reduced environmental impact from mining extracting fresh raw materials.
Reduced pollution
18.
19. Limitation of textile product
Recycling………
High upfront capital costs.
Recycling sites are always unhygienic, unsafe and unsightly
Products from recycled waste may not be durable.
Recycling might not be inexpensive
Recycling is not widespread on large scale
20. We can learn this slide…….
To know about Textile recycling.
Also acquainted Textile wastes categories.
Percentage usage of discarded textiles
Introduce recycling operation.
Textile product recycling behaviors.
Values for second hand product.
Cotton and Denim fabric recycling process.
