Abstract
A woven gauze fabric excellent in balance between breathability and heat-retaining property, transparency preventing property, and good touch feeling (softness). The woven gauze fabric includes a surface layer G1 and a back layer G3, wherein the layer G1 and G3 are directly and/or indirectly joined together. The layer G1 is formed of a hollow yarn having a yarn count of 30-50 (both inclusive), and the layer G3 is formed of a hollow yarn having a yarn count of 30-50 (both inclusive). In a case where the woven gauze fabric is a triple gauze including a middle layer G2, the hollow yarn of the layer G1 and G3 have a yarn count of 40-50 (both inclusive). In a case where the woven gauze fabric is a double gauze, the hollow yarn of the layer G1 and G3 have a yarn count of 30-40 (both inclusive).
Claims15
A woven gauze fabric comprising:
- a surface layer and a back layer;
- wherein the surface layer and the back layer are indirectly joined together,
- wherein the surface layer is formed of warp yarns and weft yarns which are composed of a first hollow cotton yarn having a yarn count of 30-50 (both inclusive), the surface layer having a flat surface,
- wherein the back layer is formed of warp yarns and weft yarns which are composed of a second hollow cotton yarn having a yarn count of 30-50 (both inclusive), the back layer having a flat surface,
- wherein the first hollow yarn of the surface layer and the second hollow yarn of the back layer have a yarn count of 40-50 (both inclusive),
- wherein at least one middle layer is interposed between the surface layer and the back layer, the middle layer is formed of warp yarns and weft yarns, and
- wherein the at least one middle layer of a plurality of middle layers is formed of a single non-hollow yarn having a fine count that is finer than the first hollow yarn of the surface layer and the second hollow yarn of the back layer,
- wherein surfaces of the layers are separated and substantially spaced apart from each other, and
- wherein the surface layer and the back layer are indirectly joined together comprising that at least one warp yarn of the middle layer entwines at least one weft yarn of the surface layer, and at least one warp yarn of the middle layer entwines at least one weft yarn of the back layer, each layer is configured to move slightly between each other.
