Abstract: A flocked polyurethane foam fabric and method for manufacturing the same for which flock fibers imbedded in an adhesive on the foam are permanently flattened and entangled. Dry ink is transferred onto the flock fibers at the same time that flattening of the fibers is taking place. The flock fibers are thermally set into their flattened state along an outer surface of a polyurethane foam base of the fabric. Flattening the flock fibers causes the entanglement of the flock, thereby improving the hand, appearance, drapeability, abrasion resistance, water repellency and heat insulation qualities for apparel items over that of unflattened flock fibers.

Abstract: A flocked yarn comprises a core yarn with a total denier of 140-1260, an adhesive applied onto the core yarn at an amount within predetermined range and flock fibers with a cut length of 0.5-3.0 mm which are flocked at a flocking density of not less than 30,000/cm.sup.2. The flocked yarn can be obtained by a method wherein for application of flock fibers onto an adhesive layer applied to the core yarn an electrostatic field in which an attractive force operates and an electrostatic field in which a repulsive force operates are applied either alternately by changing the polarity of one of a single pair of electrodes or, in a continuous process, sequentially by arranging two kinds of electrostatic fields. The flocked yarn thus obtained can have a good touch, a high flocking density and a high abrasion resistance.
