Background
The high-count and high-density fabric refers to a fabric which is produced by using warp and weft yarns with low raw yarn number and high warp and weft density. However, the definition of high count and high density fabric depends on the specific raw materials used, for example, for cotton fabric, the linear density of the yarn is below 11.7tex, which is called high count yarn, according to the regulation of GB/T5325-1997 combed polyester-cotton blended natural color cloth; the high count is the premise of high density, the density of the fabric is divided into the warp density and the weft density, generally, the thinner the yarn count is, the higher the possible density is, so the high density fabric is usually based on the premise of high count, and the fabric with the warp density and the weft density of 800 pieces/10 cm or more is customarily called the high density fabric. The existing high-count and high-density fabric has a plurality of difficulties in the production process. Preferably, the raw materials of the high count yarn are fine denier or ultra-low denier chemical fiber filament, the bundling property is poor, and the strength of the monofilament is low. Secondly, although textiles made from natural fibers feel soft, comfortable and safe to use, their strength is weak; when natural fibers are formed into composite yarns with polyester and polyamide, they do not have a sufficiently soft hand although the strength of the yarn is improved.
