1. The utility model provides a cotton sense composite yarn, has sheath yarn and core yarn, characterized by:

  • the total titer of the composite yarn is below 25dtex, the single filament titer of the core yarn and the sheath yarn is 0.5dtex to 2.0dtex, and the filament length difference between the sheath yarn and the core yarn is 2 percent to 15 percent;

    the number of the filament turns of the composite yarn with the height less than 0.35mm is more than 2000 per 20m, and the core yarn and the sheath yarn are respectively polyester filaments, polyamide filaments or a mixture of the filaments;

    the composite yarn is prepared by the following method;

    selecting fiber number of 5-12 dtex FDY as core and sheath yarn, forming composite yarn after air texturing processing and heat treatment device processing, wherein during air texturing processing, overfeeding rate of the core yarn is 2-10%, overfeeding rate of the sheath yarn is 5-30%, overfeeding rate of the sheath yarn is greater than overfeeding rate of the core yarn, air pressure added in a nozzle is 6-12 kg, and the heat treatment device processing technology is as follows;

    the length of the heat processor is;

    1.0-2.0 m, 130-250 deg.c and heat treatment time of 0.1-0.7 s, and the nozzle is a taslon air deformation nozzle.
