Intertek's tailored solutions enable retailers, brands and manufacturers of textile products, apparel and home textiles to ensure the safety, quality and performance of their products with precision, resulting in increased speed to market.
Intertek developed a testing method to help verify the authenticity of recycled polyester (PET) bottles used in yarn, textile and garment production.
Post-consumer PET from bottles is an important source of recycling and up-cycling for the apparel and footwear industry, with 8% of the world production of PET fibres comprised of recycled PET (R-PET). The increased demand of R-PET is driven by end users and the commitment of consumer brands to reach circular economic sustainability.
R-PET from bottles can be identified by analysing the typical marker found in PET bottles, but not in virgin PET/PES for fiabre production. Intertek’s approach is based on determining a unique marker for R-PET from bottles using chemical analysis, so that our customers are able to verify the use of R-PET from bottles in the products.
Intertek’s Recycled Polyester Verification can be used by vendors and factories to verify the content of yarns, fabrics and garments; and by brands and buyers to verify recycled polyester claims.
