With the continuous development of textile technology and the change of consumption concept of people, the nylon and nylon/spandex fabrics have higher requirements on functionality, comfort, health, environmental protection and health care, and the moisture absorption and sweat releasing performance of the nylon and nylon/spandex fabrics become the first choice factors for people to buy clothes. The traditional nylon, nylon/spandex fabric is poor in comfort level, the additional value is not high, and the requirements of people on the nylon and nylon/spandex fabric cannot be met, so that the nylon and nylon/spandex fabric has a very wide market development prospect.

In recent years, one-way sweat-guiding, comfortable and quick-drying fabric fabrics formed by weaving and compounding two raw material yarns are developed at home and abroad, and the fabric fabrics have the common characteristics of quick sweat absorption, quick transmission and diffusion to the outer layer of the fabric, maintenance of a dry and comfortable microclimate environment inside the clothes, and no adhesion to skin and cool and comfortable feeling of the clothes in a sweat-showing state. At present, the nylon, nylon/spandex fabric is mainly developed by weaving two kinds of yarns with different hydrophilic and hydrophobic properties through special fabric tissues, so that the hydrophobic chemical fiber yarns are mainly presented on the inner surface of the garment, and the hydrophilic yarns are mainly presented on the outer surface of the garment, thereby achieving the effects of quickly absorbing sweat and quickly transmitting and diffusing to the outer layer of the fabric. In practical application, the cost of raw materials, weaving efficiency, fabric thickness, air permeability and the like are considered for weaving the moisture-absorbing and sweat-releasing nylon, and therefore, the mode of interweaving moisture-absorbing and sweat-releasing fibers and cotton is mostly adopted, but the moisture-absorbing and sweat-releasing nylon fabric has poor moisture-absorbing and sweat-releasing performance, particularly the fabric with high spandex content has poor hand feeling, poor water-absorbing and washable performances, cannot meet the practical performance of the fabric, and has higher cost. Therefore, a special finishing agent is needed to solve the defect that the existing nylon fabric has poor moisture absorption and sweat releasing performance.
