Abstract: A knitted fabric possessing a porosity of at most 80% and a surface contour of at most 6, therefore having a woven fabriclike appearance and hand, is manufactured by uniformly pressing a primary knitted fabric containing at least 50% by weight of thermoplastic synthetic fiber with a presser face under 5 to 35 kg/cm.sup.2 pressure at a temperature lower than the melting point of the synthetic fiber but not lower than 90.degree. C so as to compress and heat-set the primary fabric in a thickness of 95 to 55% based on that of the starting primary fabric.

Abstract: Multi-component mixed filament, wherein at least two spinning materials having poor affinity are mixed and dispersed in unitary filament in a nebular configuration containing at least 50 stars at least in one portion of the cross-section of the filament and the nebular configuration continues substantially in the longitudinal direction of the filament is manufactured by subjecting said spinning materials to at least eight times of "joining and dividing step in different phase" repeatedly to layer-multiply said spinning materials so as to form a nebular configuration in the cross-section of the resulting filament and then extruding the resulting mixture from orifice in a spinneret. In this manufacture, the preferable combinations of said two spinning materials having poor affinity are polyamide-polyester, polyamide-polyalkylne oxide, polyester-polyalkylene oxide and polyamide-polyolefin.
