Successful carpet sorting trial completed by Tailorlux and Weserland
Weserland and Tailorlux have completed a successful carpet grading trial using Tailorlux’s optical fingerprint. The mark was dissolved in a coating of labeled ethylene vinyl acetate (EVA) polymer dispersion from Weserland and can be detected by a hyperspectral camera in the range of 500-1000 nm and 970-1700 nm.
This NIR manipulation of carpets can be used by sorting centers with standard NIR to identify specific material blends that have been assigned to the NIR manipulation. Tailorlux has thus achieved for the first time that carpets can be marked with their invisible markings and recognized via a sorting system.
Weserland is a specialist in the production and development of aqueous dispersions and compounds for latex vulcanization and carpet backing. Both companies got to know each other during their participation in the ReNewTex network and decided to conduct a trial with the optical fingerprint and Weserland coating.
