    Abstract: A leather-touch pile fabric in an identifiable double layer structure consisting of an upright hair-like raised fiber layer and down-like raised fiber layer which is used as artificial leather. The method of this invention provides a pile fabric knitted of pile yarns composed of a mixture of polyester fibers in finite length sharpened at tips to be used as upright hair-like fibers and other polyester fibers in finite length to be used as down-like fibers more likely to be eroded by alkali treatment than said polyester fibers that compose said upright hair-like fibers, in which, after adding alkaline treating agent (6) having a specific viscosity to the surface of a raised fiber layer of said knitted pile fabric, heat-treatment is applied to said fabric so as to shorten the length and sharpen the tip of each down-like fiber, whereby a pile fabric (1) having upright hair-like raised fibers (2) sharpened at tips and down-like raised fibers (3) sufficiently uniform in length is obtained.

    Abstract: An artificial fur having an at least double erect pile layer structure comprising an erect pile layer of long fibers and that of short fibers. The lightness of the short fibers is lower by 0.5 or above, preferably by 2.5 or above, than that of the long fibers. This artificial fur has an excellent appearance and gives an impression of high-gradeness comparable to or even exceeding those of a natural fur.

    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: A process for making a fasciated spun yarn by drafting and pneumatically false twisting a bundle of staple fibers is disclosed. In the method, the width W (mm) of a bundle of fibers measured just upstream of the nip point of a pair of second rollers of a drafting zone and a yarn count N (Nm) of the spun yarn are set to satisfy the following equation:and the overfeed ratio of the bundle of fibers during the false twisting operation is 5% at most. The fasciated spun yarn made by this process has a straight shape, resembles a ring-spun yarn and has sufficiently stable strength.
