Abstract: PURPOSE:To obtain covered elastic yarn having good covering properties, a compact yarn shape, low torque characteristics, good stretchability, etc. CONSTITUTION:The objective covered elastic yarn is produced by using conjugate filament having structural crimps such as polyurethane-polyamide eccentric core-sheath type conjugate filament. After covering with the conjugate filament, crimps of the conjugate filament forming the covering yarn are developed.

Abstract: PROBLEM TO BE SOLVED: To provide a false twisted aliphatic polyester yarn having biodegradability, forming a woven or knitted fabric excellent in gloss, a touch, color development and a feeling and having many crimps and low shrinkage in boiling water, and to provide a method for stably producing the yarn. SOLUTION: This false twisted aliphatic polyester yarn comprises an aliphatic polyester having ≥130°C melting point and has ≥15% contraction recovery (CR) and ≤10% degree of shrinkage in boiling water. The method for producing the false twisted aliphatic polyester yarn comprises touching 3-30% effective length of the heating device of the yarn and untouching the remainder of the effective length of the yarn.
