Recycled sewing thread also referred as GRS sewing thread. GRS means Global Recycled Standard: Sewing thread made of 100% recycled polyester(100%post-consumer material made from PET materials), bleached, dyed (in a limited range of 20 disperse dyestuffs including 1 fluorescent red dyestuffs)and finished(based on material partly pre-certified according to OEKO-TEX STANDARD 100)

Process of manufacturing recycled sewing thread
Recycled sewing thread is made from recycled materials, such as post-consumer plastic bottles or reclaimed fabric fibers.
- Collection of Waste Materials: Thread raw materials are obtained from recycled PET bottles
- Flakes and Granules: Bottles are shredded into flakes and melted
- Recycled Raw Fibers: The melted flakes or granules are pushed through tiny holes to form fibers.
- Spinning into Yarn: The fibers are further processed into threads or yarns.
Using recycled sewing thread offers several environmental benefits. It helps reduce waste by repurposing materials that might otherwise end up in landfills. Additionally, it conserves resources and reduces the carbon footprint associated with producing new fibers. Recycled threads are increasingly popular in eco-conscious fashion and textile industries, contributing to more sustainable production practices.
