Hollow fabric and manufacturing method thereof

Abstract

A hollow fabric is obtained by providing cotton blended yarns and alkali-soluble polyester yarns which are arranged in a ratio of 10:2 as warp yarns, and providing cotton blended elastic yarns and alkali-soluble polyester filaments which are arranged in a ratio of 6:2 as weft yarns. The warp yarns and weft yarns are interwoven into plain weaves, and the plain weaves are subjected to alkali solution to remove the alkali-soluble polyester filaments, thereby obtaining greige cloth having meshes. The greige is subjected to boiled bleaching, softening and drying to obtain the hollow fabric. By optimizing the ratio of yarns and using a boiled bleaching, softening and drying process, a soft, smooth and fluffy product is produced with humidity-absorbing and breathability characteristics.
