摘要:
A process to produce a plyed holographic yarn in which the slit film is allowed to be pulled from its source rather than being driven by drive rolls. The slit film and at least one other yarn are plyed and textured in an air texturing jet.

A furred thread is produced by a sequence of steps, which include impregnating a fur material with moisture. The material is stretched in a stream direction of hairs of the material and dried. The material is cut in the stream direction of the hair to produce a fur strip, which is impregnated with moisture, twisted in a manner such that its hair side appears outwardly while the strip is stretched in its longitudinal direction, and dried to produce the furred thread.

In a fur fabric having a fur yarn woven into a base fabric: a fur strip having a furry and a bare skin side is helically coiled around a rodlike mold form in a condition in which the furry side is disposed outside the form so as to form an assembly; the form is removed from the assembly to form a tubular roving which is further spun to form a yarn which is folded double to have its halves self-spun together under the influence of resilient shrinking effort of the halves, so as to form a completed single yarn which is woven into the base fabric in a condition in which a first one of the completed yarns is helically coiled clockwise around a first one of the warp threads, and a second yarn adjacent to the first one of the yarns is helically coiled counterclockwise around a second warp thread adjacent to the first one of the warp threads, so as to have adjacent ones of the completed yarns be opposite in coiling direction.
摘要:
A thread-like continuous retroreflective fiber and method of making same, comprising the steps of laminating a thin film of retroreflective material to a supporting polyester film, and then slitting the laminate to form narrow strips of retroreflective material having sufficient strength to be combined with other fibers to form a composite yarn having retroreflective characteristics, which composite yarn may then be woven, knitted, or spun to provide a fabric having retroreflective characteristics.
摘要:
A fur-skin strip material consisting of yarn-like fur-skin strips that are knitted, crochete or woven to form a fabric and the like. The fur-skin strip material is fine, smooth and soft and can be produced in an industrial scale at a lower cost.The yarn-like fur-skin strip is made by cutting a hairy-coated skin of a fur-bearing animal. The skin will be placed, the fur side down, on a supporting device that has numerous needles so that the leather side of the skin will be made substantially flat, enabling only the leather side of the skin to be applied with a laser beam or water jet and thereby cutting the skin uniformly into fine strips of furry material.
摘要:
Untwisted synthetic resin string comprising two rolled portions each spiral in cross section and formed by inwardly rolling toward each other the opposite side edges of a strip of thermoplastic resin film stretched at least longitudinally thereof. The rolled portions extend longitudinally of the string in parallel with each other and are partially adhered together longitudinally thereof. Also disclosed are an apparatus for manufacturing the untwisted string from a strip of thermoplastic resin stretched at least longitudinally thereof and another apparatus for manufacturing an untwisted string having a single rolled portion from like resin strip.
摘要:
A striated film is fibrillated by passing the film between a pair of opposing rotating beater bars. In this manner uniform tension is maintained across the film urging the film in engagement with serrated edges which may be on one or both of the beater bars. This system permits higher film linear speed than can be achieved in previous prior art beater bar systems.

A rotatable beater bar, used for fibrillating film, comprises serrated edges mounted thereon in such a manner that the edges can be removed therefrom or adjusted according to the type of fibrillation desired.
