The special selection of raw materials determines that this fabric is destined to be extraordinary; in terms of technology, the six production processes of shrinking, pre-setting, dyeing, drying, sanding and finished product setting lay the foundation for the unique feel of the fabric; in terms of performance, this fabric has a soft feel and is also antibacterial and hygroscopic. Summary of the invention

[0003] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide an N-CD composite yarn antibacterial and wear-resistant sports fabric and a preparation method thereof, wherein the preparation method mainly comprises the following steps:

[0005] Preferably, the configuration of the yarns in step S1 is: the 1st to 14th routes are connected to yarn A and yarn C, the 15th route is connected to yarn A, and the 16th route is connected to yarn B.

[0006] Preferably, the yarn A in step S1 is a 145D / 120F nylon / regenerated cationic composite yarn, wherein the nylon is 70D / 48F full-dull FDY and the regenerated cationic yarn is 75D / 72F DTY.

[0007] Preferably, the yarn B in step S1 is 20D spandex.

[0008] Preferably, the yarn C in step S1 is 30D / 24F FDY polyester.

[0010] Improving the yarn configuration and weaving process of fabrics is a method to improve the moisture absorption and antibacterial properties of fabrics. The present invention preferably uses spandex and nylon / regenerated cationic composite yarns with innovative yarn configurations, and weaves them with flat needles and floating thread structures to obtain air layer fabrics, which maintain the elasticity and softness of the fabrics. It can not only conduct moisture in a unidirectional manner to ensure the dryness of the skin-contacting surface after sweating, but also has a good warming effect. The moisture conduction and perspiration process of the fabric includes wetting, moisture absorption, diffusion, and evaporation. The capillary effect of the fabric is used to quickly transfer the sweat on the body surface to the surface of the fabric through absorption, transfer, diffusion, etc., and then evaporate.

Nylon has excellent wear resistance, skin affinity and high aesthetics, while regenerated cationic has good corrosion resistance and antibacterial properties. Spandex has good resilience and wrinkle resistance, which can improve the elasticity and durability of the fabric. It is also heat-resistant and not easy to deform. Polyester has the characteristics of high strength, good resilience, good wear resistance, and good chemical stability. Through this innovative yarn configuration, the fabric can have the advantages of various yarns, such as softness, hygroscopicity, wear resistance, elasticity and antibacterial.
