Microfiber cloths are mostly made of polyester or polyamide filament yarns. Microfibers are about ten times finer than a human hair, and are processed into a particularly close-meshed knitted or woven fabric.
The finer the yarn, the better it feels. Hardly surprising that virtually half of all yarns manufactured are now made from microfibers. Above all, the apparel sector offers important applications: underwear, men’s and women’s outer garments as well as a broad spectrum of sports and functional textiles. However, the yarns are also used to manufacture home textiles, decorative and automobile applications along with high-end cleaning materials.
Microfilament yarns are yarns with filament titers of less than 1 dpf. Those with individual filaments of less than 0.5 dpf are described as super-microfilament yarns. While the comparably complex bi-component spinning processes are meanwhile able to manufacture filament titers that are less than 0.0001 dpf, conventional melt spinning processes currently permit process-reliable and simultaneously efficient filament titers of down to 0.3 dpf.
Numerous application possibilities: Bi-component yarns
Bicomponent yarns offer a huge range of possible cross-sections. In general, these yarns comprise two different polymers, which give them specific properties. Bicomponent yarns with the corresponding cross-sections are manufactured depending on the desired application. Here, the four best-known cross-sections are core-sheath, side-by-side, segmented-pie and islands-in-the-sea.
