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 alkali-treated fabric thereby shortening the under-fur fibers and sharpening the leading terminals of the under-fur fibers.
