Title:
TWISTED YARN AND TWISTED YARN STRUCTURE USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/111830
Kind Code:
A1
Abstract:
A twisted yarn (1) has a core-sheath structure in which a core yarn (2) comprising a high-tensile-strength fiber is covered with a sheath yarn (3) comprising a thermoplastic fiber or a natural fiber. A differential core yarn twist coefficient K calculated by formula (1) is in the range of 0 to 60. K = T/(10,000/D)1/2 (1) (where, D represents the total fineness (dtex) of the core yarn, T represents the absolute value (times/m) of (twist count of core yarn before sheath yarn is wound) – (twist count when core yarn and sheath yarn both are wound).)
