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.

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.

Abstract: Disclosed is a wash-and-wear coat which comprises outer cloths, lining cloths, interlining cloths and sewing threads all of which exhibit very small shrinkage of 1% or less after laundering, the interlining cloths bonded to the outer cloths having a high peeling strength of at least 400 g/cm.sup.2 after the first time of laundering and the lining cloths having a proper air permeability of from 100 to 300 ml/cm.sup.2 /second. The coat can be provided with a pocket located in the back part lining cloth of the coat which is capable of containing therein the coat itself.

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.

Abstract: In a knitting machine in which upon the application of abnormal tension to yarn, the yarn is released from a yarn engaging element and simultaneously the knitting machine is halted. A yarn replacing apparatus is provided comprising at least one vertical motion mechanism for receiving yarn released from a yarn engaging element and moving it upward into reengagement with the yarn engaging element. The vertical motion mechanism further includes a detecting device for detecting an abnormal condition in the yarn, whereby when abnormal tension applied to the yarn has been removed, the vertical motion mechanism continues to operate, whereas when the abnormal tension applied to the yarn has not been removed, the vertical motion mechanism is halted, and the knitting machine automatically again comes into operation only after the reengagement of the released yarn with the yarn engaging element.

Abstract: A pattern for a pattern wheel used in a circular knitting machine is set by detecting a blade of the pattern wheel to actuate a tape reader which has been patterned in advance, and pushing a jack of the pattern wheel in response to the signal from said tape reader.
