A three-bar moldable warp knitted fabric having a satin-like technical back suitable for use in forming seamless molded breast cups for women's brassieres is produced on a Raschel warp knitting machine by knitting satin-effect yarns on the machine's bottom bar in coursewise extended underlaps producing the satin-like technical back of the fabric, knitting high elongation-high shrinkage monofilament POY draw-warped polyester yarns on the machine's middle bar to form a stabilized fabric ground structure, and inlaying elastic yarns with the machine's top bar to impart a compacted stitch density to the fabric when relaxed. When placed over a heated molding surface of a breast cup mold, the ground yarns shrink sufficiently and become heat set to collapse the fabric into a permanent shape conforming to the molding surface, the elastic yarns maintaining sufficient stitch density in the molded fabric to retain a uniform satin-like surface effect at the fabric's technical back.
A warp knitted fabric characterized by a moldability to collapse and become set into a permanent shape conforming to a three-dimensional mold when subjected to heat essentially without distension of the knit structure of the fabric, said fabric comprising a set of yarns warp knitted in underlaps oriented sufficiently coursewise at the technical back of the fabric to provide a satin-simulative surface effect and a set of ground yams warp knitted in a stitch pattern forming a stabilized fabric ground structure, the ground yarns comprising POY polyester yarns having a substantially high denier per filament of at least about 10 denier per filament, a substantially high degree of elongatability of at least about 55% elongation, and a substantially high degree of shrinkability of at least about 9% shrinkage to impart a collapsibility and setability to the knitted structure of the ground yams in the presence of heat.
A warp knitted fabric of a three-bar construction characterized by a moldability to collapse and become set into a permanent shape conforming to a three-dimensional mold when subjected to heat essentially without distension of the knit structure of the fabric, said fabric comprising a set of yams warp knitted in a 4-6, 2-0 stitch pattern forming underlaps oriented sufficiently coursewise at the technical back of the fabric to provide a satin-simulative surface effect, a set of elastic yarns warp knitted in a 0-0, 4-4 inlaid pattern, and a set of ground yams warp knitted in a 2-0, 2-4 stitch pattern forming a stabilized fabric ground structure, the ground yarns comprising monofilament POY draw-warped polyester yarns having a substantially high degree of elongatability of at least about 60% elongation and a substantially high degree of shrinkability of at least about 10% shrinkage to impart a collapsibility and setability to the knitted structure of the ground yarns in the presence of heat, the elastic yarns constricting the fabric when relaxed to impart a compacted stitch density to the fabric to enhance the coursewise orientation and the satin-like surface effect of the satin-effect yarns.
