FALSE-TWIST TEXTURED YARN FOR ADHESIVE TAPE BASE FABRIC AND METHOD FOR PRODUCING THE FALSE-TWIST TEXTURED YARN

摘要

PROBLEM TO BE SOLVED: To provide a false-twist textured yarn scarcely causing breakage and/or fluffing even if unreeled in high speed and excellent in weavability, and capable of giving adhesive tapes good in tearability by hand, free of thickness unevenness and uneven feeling and good in appearance. ;SOLUTION: The false-twist textured yarn for adhesive tape base fabrics comprises as the sheath a polyester multifilament A containing 0.5-3.0 wt.% of a polymethyl methacrylate-based polymer or polystyrene-based polymer and as the core a polyester multifilament B substantially free of the above polymers, wherein at least a part of the filaments in the multifilament A contains mutually fused and hardened portions. This false-twist textured yarn is 2-7% in crimp percent (T) and 5-10 in silk factor (SF).;COPYRIGHT: (C)2004,JPO
