Abstract
Abstract A brassiere having breast cups molded from a heat settable, thermoplastic fabric, such as polyester, of warp knit construction and including top, middle and bottom guide bar yarns. The bottom and/or middle guide bar yarns have a denier per filament of at least 10. The stitch construction is particularly selected so that the bottom and middle guide bars run in opposition to each other and each have an underlap length which extends between at least two wales. Preferably, the stitch configuration of the bottom guide bar should be 1-0/1-2 and the middle guide bar should be 1-2/1-0. Alternatively, a stitch configuration of 1-0/2-3 may be employed in the bottom guide bar and 2-3/1-0 in the middle guide bar. The top guide bar primarily controls the aesthetics of the fabric and preferably may have a stitch configuration of 1-0/2-3 or, alternatively, a stitch configuration of 1-0/3-4. The molded bra cups have excellent shape retention properties, especially after repeated washings.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
A molded three-dimensional breast cup for a brassiere comprising a warp knit fabric of thermoplastic yarns throughout, said fabric being at least a three guide bar fabric, including top, middle and bottom guide bar yarns having a denier per filament of at least 10, said bottom and middle guide bar yarns being in opposition to each other and each having underlap lengths which extend at least two wales, but not more than three wales, said fabric having a degree of stretch sufficient to enable said fabric to distend during molding from an initially planar condition to a three-dimensional configuration, and in which said warp knit fabric yarns form stitches with overlaps and underlaps that are substantially dimensionally stabilized, said fabric top bar yarns appearing on both surfaces of the molded breast cup for soft molded fabric surfaces.
Claim 2
Dependent Claim
