Near-infrared spectroscopy – collected applications for the textile industry
2014-09-05

Near infrared spectroscopy (NIRS) has been used in the textile industry to differentiate fiber types for carpet recycling. Metrohm is pleased to present a collection of 15 applications for the straightforward analysis of wool, cotton, nylon, polyester, and other fibers. The collected applications are available free. 

Blend analysis of different polymer fibers can be analyzed with NIR spectroscopy as well. Real-time analysis of the application of polyvinyl alcohol (PVA or PVOH) sizing to warp yarn has been done with NIR online process analyzers. Common fibers identified with NIRS include: cotton/linen, merchandized cotton, acrylic, modified acrylic, acetate, triacetate, Nomex®, Kevlar® (K-29, K49, and K129), nylon-6, nylon-6,6, silk, polyester, cationic and disperse dyeable polyester, polypropylene, PVA and PVC.
