Process for continuously manufacturing a colored flocked support

摘要

A flocked and dyed cloth backing (S) is made by application (1) of polymerizable resin (RP) layer to surface of cloth backing; projection (2) of white or unbleached polyester flock fibers (FF) onto resin layer; polymerization (3) of resin to fix the flock fibers on cloth backing; deposition (4) of sublimable dye (E) on flocked surface; and sublimation (4) of deposited dye to dye the flocked fibers. The continuous manufacture of flocked and dyed cloth backing involves successive stages of application of polymerizable resin layer to surface of the cloth backing; projection of white or unbleached polyester flock fibers onto the resin layer; polymerization of the resin to fix the flock fibers on the cloth backing; deposition of sublimable dye on the flocked surface of the cloth backing; and sublimation of the deposited dye to dye the flocked fibers. During projection, polyester super microfibers are used with a titer of less than 0.5 Dtex and a length of 0.2-0.5 mm.
