Title:
環境に優しい伸縮性生地を作製するための綿ベースの伸縮性糸
Document Type and Number:
Japanese Patent JP7418427
Kind Code:
B2
Abstract:
A method for making an elastic core yarn includes covering an elastic core having a fiber of natural rubber with metric count 200-1000 dtex with a cotton-based covering yarn. The elastic core and the covering yarn are conveyed such that the covering yarn laterally attains a proximity of the elastic core in a wrapping space. The covering yarn is helically wrapped about the elastic core. The conveying speed, and therefore the winding/unwinding speed, is selected such that the elastic core is stretched to a stretching ratio of at least two, and the covering yarn becomes twisted with a final twist direction opposite to its initial twist direction, and forms T coils per length unit of the elastic fiber set between a minimum value T0 and a maximum value T1. An elasticized yarn is thereby obtained, and a fabric, in particular a denim type fabric, is manufactured from this yarn.
