Microfibre Production Technology
topic
Microfibre yarn production extrudes segmented-pie or islands-in-sea bicomponent filaments that are subsequently split or dissolved to produce sub-denier microfilaments of 0.05 to 0.3 decitex per filament through mechanical splitting during weaving and finishing operations or chemical dissolution of the sea polymer by alkali treatment of polyester-nylon bicomponent yarns, producing the ultra-fine filaments of microfibre fabrics with exceptional softness and drape.
Role
Enables production of sub-denier filament yarns for microfibre fabrics through bicomponent extrusion and subsequent filament generation that achieves filament fineness below the practical limit of direct melt spinning, with microfibre filament fineness being the property that provides the distinctive softness, drape, and cleaning performance of microfibre suede, cleaning cloth, and sportswear fabrics that coarser filament yarns cannot replicate.
