  • Patent number: 4702949
    Abstract: A woven fabric, namely a velours, consists of a foundation fabric and a pile layer of synthetic fibers, at least the pile fibers having a strong crinkle in the untreated woven state. The fiber sections of the pile fibers projecting out of the foundation fabric are permanently uncrinkled, straightened and largely paralleled in the nap surface area and assume an essentially straight position while the pile fibers in the area of the foundation fabric still have the initial crinkle. Due to this, a very easy-to-care-for velours is created with excellent pile retention in the foundation fabric.
