  • Patent number: 4886693
    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.
