<P>PROBLEM TO BE SOLVED: To produce compound paperfiber thread which can prevent that only paperfiber is cut and fluffing is generated when tensile force is added to the thread. <P>SOLUTION: A core yarn 20 of compound paperfiber thread 10 has a paperfiber thread 21 which is filamentous flat tape-shaped paper and a center yarn 22 consisting of viscose rayon spun yarn of Z-twisting direction. In the core yarn 20, the paperfiber thread 21 is overfed with respect to the center yarn 22. A covering yarn 30 is wrapped around the core yarn 20 in such a state in a spiral to expose some of the core yarn 20. The covering yarn 30 consists of viscose rayon spun yarn of Z-twisting direction, and is coiled with the Z-twisting direction same as its twisting direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
