METHOD FOR MANUFACTURING COVERING YARN HAVING PP EFFECT YARN YARN AND YARN PROCESSING APPARATUS PROVING PP EFFECT YARN OF COVERING YARN

摘要

The present invention relates to a thread processing apparatus for preparing the PP material sheath 4 of the covering yarn 6, the PP material raw fiber yarn supplied from the supply bobbin 30 and to be used as the sheath 4 of the covering yarn 6 ( A solid soft paraffin wax cake in which the tension control device 40 for tensioning 4b) is adjusted by the tension control device 40, and then the PP material fibril yarn 4b is idlely rotated by the advancing motion of the yarn. Covering with a PP material super yarn (4) composed of a waxing device (50) that provides a PP material processed fiber yarn (4a) coated with 52 to be wound on an H-shaped bobbin (16) with a wax-coated yarn surface It can be used to manufacture yarn (6).
