    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: 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.
