Background

With the continuous progress of society, textile technology and textile equipment are continuously developed, new yarns are continuously appeared, and vortex spun yarns are one of the most attractive yarns. Vortex spinning is a new technology in the existing spinning system, compared with the traditional ring spinning: the method has the characteristics of short spinning flow, high production efficiency, online quality monitoring, high automation intelligent degree and the like, and also has the advantages of greatly reducing labor, reducing yarn hairiness and the like. Therefore, the vortex spun yarn is processed into needle and cotton fabrics, and has the advantages of smooth cloth cover, less hairiness, good wear resistance, good fuzz and pilling resistance, bright color, moisture absorption, quick drying and the like. At present, the vortex spinning technology is researched a lot at home and abroad, but the research on the linear performance of the vortex spinning is less.

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 less than 11.7tex, which is called high count (low count) yarn, according to the GB/T5325-1997 combed polyester-cotton blended natural color cloth; the high count (low 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 density is possible to achieve, so the high density fabric is usually based on the high count, and the fabric with the warp density and the weft density of 800 pieces/10 cm or more is conventionally called the high density fabric. The existing high-count and high-density fabric has a plurality of difficulties in the production process. Firstly, 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 lower. Secondly, since the high-count and high-density fabric generally has the defects of thin yarn number (or low denier), high warp and weft density, more total warp, more tissue interweaving points and dense cloth surface, the phenomena of unclear opening, disordered yarn, fluffing, broken yarn and the like often occur in the weaving process, and the defects of serious 'three jumps' and the like of the cloth surface are caused.
