  • Patent number: 5459991
    Abstract: A composite crimped yarn comprising: at least two kinds of multifilament yarns, one of them being comprised of a crimped conjugate multifilament yarn comprising two kinds of polyester polymers different from each other in the heat shrinkability and positioned as a major component of the inner layer of the composite crimped yarn, the other of them being comprised of a crimped multifilament yarn of a single synthetic polymer and positioned as a major component in the outer layer of the composite crimped yarn. In the above, the length of the crimped multifilament yarn is 5 to 35% larger than that of the crimped conjugate multifilament yarn, part of the crimped multifilament yarn being migrated to the crimped conjugate multifilament yarn disposed in the inner layer and part of the crimped conjugate multifilament yarn being migrated to the crimped multifilament yarn disposed in the outer layer.

  • Patent number: 5102735
    Abstract: This invention relates to a latent looped yarn having loops produced by an eddy current treatment and once potentialized therein before a weaving operation and revealed in a fabric, after the yarns are woven therein at least as warp yarns, by heat treatment, to give the fabric a spunlike handling and high yarn density. This invention also provides a manufacturing method for producing the latent looped yarn and high density spunlike fabrics utilizing the latent looped yarn.

  • Patent number: 3967470
    Abstract: In apparatus for napping a circular knitted fabric between the knitting portion and the winding portion of a circular knitting machine, apparatus for napping the circular knitted fabric with emery in the form of a belt or the like. The invention includes a means for stretching the knitted fabric coursewise and an adjacent emery supporting base, an emery supporting frame structured to support said emery in the form of a belt or the like, and a driving portion provided to move said emery in a coursewise direction with respect to said circular knitted fabric while it is stretched coursewise.
