    Abstract: An apparatus for manufacturing a fluffy yarn used in combination with a yarn-advancing mechanism and having one or more fluffraising members axially rotational in contact with a ballooning portion of the advancing yarn for partially and intermittently cutting fibrous materials composing the yarn. The fluff-raising member may be rotated positively.

    Abstract: Disclosed herein is a twisted yarn comprising at least two bundled sheaves of staple fibers, each sheaf having an initial twist of substantially zero, the sheaves of staple fibers being mutually twisted to form the yarn. The coefficient of finishing twist utilization as defined in the specification is at least 150%. Also disclosed is a method of producing a twisted yarn comprising drafting a sheaf of staple fibers, supplying the sheaf to a bundling zone to reduce it to a bundled sheaf having an initial twist of substantially zero, drafting another sheaf in a similar manner, doubling at least two such bundled sheaves of staple fibers, and twisting them together.

    Abstract: AN IMPROVED METHOD AND APPARATUS FOR MANUFACTURING ARTIFICIAL FURS An improved method for manufacturing an artificial fur from a material pile cloth such as a double velvet weave fabric, a knitted pile fabric provided with two ground constructions and a plurality of connecting piles connected these two ground constructions, and a material pile cloth provided with a plurality of looped piles projected upward from a ground construction fabric or knitted fabric or non-woven fabric. In the method of this invention, the continuity of the pile yarns of the material pile cloth is broken by sliding separation, so as not to break at least a partial number of material fibrous material which will becomes guard hairs of the final artificial fur. In the apparatus for carrying out the above-mentioned method, a separating member having a unique construction is preferably utilized so as to carry out the above -mentioned breaking of the continuity of the pile yarns of the material pile cloth.

    Abstract: In an artificial fur made from a pile cloth provided with a ground construction and numerous pile fibers projected upward from the ground construction, the pile fibers consist of a first group of pile fibers which form a layer of guard hair in the fur and a second group of pile fibers which form a layer of under fur in the fur, wherein each fiber of the first group is provided with a tapered free end portion and a tapered end portion firmly held by the ground construction; the pile fibers of the first group are longer than the pile fibers of the second group, while the thickness of the main portion of the former is thicker than the thickness of the latter. The above-mentioned artificial fur is manufactured by a first step of forming a material pile cloth provided with a ground construction and numerous yarn-like piles projected upward from the ground construction, and a second step of raising the side of said yarn-like piles. An intermediate step of applying a backing treatment to the pile cloth is preferably applied as a process between the above-mentioned two steps of processing. As a final process, a finishing process is applied to the material pile cloth. A conventional dyeing process can be applied.

    Abstract: This invention is directed to a fur-like pile fabric of two-layer construction formed of guard hair fibers and under-fur fibers and used as artificial fur and a method for the production thereof. This invention produces a pile fabric 1 possessing guard hair fibers 2 having sharpened leading terminals and under-fur fibers having a satisfactorily uniform length by a method that comprises preparing a pile knitted or woven fabric with a pile yarn obtained by mixing limited-length polyester type fibers for guard hair fibers of sharpened terminals with limited-length polyester type fibers more susceptible to the action of an alkali treating agent and used for under-fur fibers, imparting an alkali treating agent 6 of a specific viscosity to the hair-raised surface of the pile knitted or woven fabric, and thereafter heat-treating the alkalitreated fabric thereby shortening the under-fur fibers and sharpening the leading terminals of the under-fur fibers.
