Abstract: In recent years, multi-functional composite healthy and comfortable fabrics are the development direction of current fabrics. Under the high temperature in summer, the human body will produce a lot of sweat after exercise. As a product in direct contact with the human body, clothing is easy to attach to the skin surface and form a high temperature and humidity climate environment with it, and produce sticky, stuffy and airtight feeling. And because of the porous structure and large specific surface area, it is easy to absorb sweat and a large amount of oil secreted by human metabolism, providing a good environment for the attachment and reproduction of bacteria and other microorganisms. The pungent odor and indirect transmission produced in the process of reproduction are also important sources and transmission routes of diseases, thus bringing hidden dangers to human health. In summer activities and work, a long time of humid and sultry environment will make the skin more prone to allergy and other inflammatory reactions and accelerate skin aging. The development of multi-functional composite fabrics with moisture absorption and quick drying, antibacterial and thermal comfort has a certain market prospect.
At present, the thermal-moisture comfort function of fabric is relatively simple, and there is little research on the multifunctional composite of fabrics realized by functional fiber mixing. The fabric modification for the hot and humid environment is mainly for the improvement of the functions such as moisture absorption and quick drying, antibacterial and heat transfer. To develop healthy and comfortable clothing fabrics under humid and hot conditions, a total of 16 types of fabrics, including A and B series, were woven with mulberry silk as warp and a blend of honeycomb antibacterial polyester fibers, tencel, honeycomb UV resistant polyester fibers, and honeycomb jade polyester fibers as weft. By testing the performance of moisture absorption, quick drying, antibacterial and heat transfer, the heat and humidity comfort was evaluated by fuzzy comprehensive analysis. The results show that the moisture absorption and quick drying properties of the yarn is related to its type, weave and density. The inhibitory effect of fabric on S. aureus and E. coli is positively correlated with the content of cellular antibacterial polyester fiber in latitude yarn, and the inhibitory effect of S. aureus is better than that of E. coli. The thermal resistance of fabric decreases with the increase of tencel content in yarn, and the heat transfer performance of fabric is best when honeycomb jade polyester fiber is contained. The results of fuzzy comprehensive analysis indicate that in the A series, the fabric woven with tencel/honeycomb antibacterial polyester fiber/honeycomb ultraviolet resistant polyester fiber (30/60/10) as weft and 16 reinforced weft satin has the best comprehensive performance; the comprehensive performance of the fabric in the B series is the best when the weft density is 46 roots/cm.
We explore the influence of fiber content ratio, fabric weave and fabric weft on the antibacterial, thermal-moisture comfort of the blended yarn, and the research results can provide reference for the design and development of multi-functional fabrics, contribute to the development of composite functional fabrics with better comprehensive performance, and promote the development of clothing fabrics in a more high-grade, more accurate and more scientific direction.
