Abstract
Official abstract text for this publication.
A stretch fabric in which one yarn of warp and weft yarns is obtained from an inelastic yarn having a crimp ratio of 5% to 30% and at least a portion of the other is obtained from an elastic yarn having a crimp ratio of 0% to 5%, and characterized in that the extension percentage in a load direction along the former yarn is 5% to 30% when weighted with a 340N/5 cm load in the load direction. The stretch fabric has excellent cushioning properties and fatigue resistance, and can be used as a material that saves space and combines holding properties with cushioning properties.
First claim
Opening claim text (preview).
The invention claimed is: 1. A stretch fabric in which one yarn of warp and weft yarns comprises an inelastic yarn having a crimp ratio of 5% to 30% and at least a portion of another yarn of warp and weft yarns comprises an elastic yarn having a crimp ratio of 0% to 5%, wherein an extension percentage in a direction of applying a load is 5% to 30% when the load is applied at 340N/5 cm in parallel to the one yarn, wherein the elastic yarn comprises a core component and a sheath component of monofilament having fusion-bonded intersections, the core component is made of a polyester-based elastomer having a melting point of 190° C. to 250° C., and the sheath component is made of a polyester-based elastomer having a melting point of 140° C. to 190° C. 2. The stretch fabric according to claim 1 , wherein the extension percentage in the direction of applying the load is 8% to 20%. 3. The stretch fabric according to claim 1 , wherein a residual strain in the direction of applying the load is 3% or less after being extended at a constant speed as repeating a loading and an unloading 300,000 times at 340N/5 cm. 4. A seat comprising, at least in a part, the stretch fabric according to claim 1 .
