真丝/锦纶交织面料的防晒与热湿舒适性能研究OA

To develop a soft,skin-friendly,and comfortable sun-protective fabric,silk was employed as the warp yarn,while the weft yarn consisted of silk combined with a UV-resistant nylon filament.Three sets of fabrics,comprising a total of 23 samples,were woven by manipulating key variables:fabric structure,weft density,and the content of nylon filament in the weft yarn.The effects of these variables on ultraviolet(UV)protection performance and thermal-wet comfort properties were subsequently investigated through experimental testing and data analysis.The results indicated that,under identical conditions,both the Ultraviolet Protection Factor(UPF)and contact cool feeling values showed a positive correlation with both nylon content and weft density.In contrast,moisture permeability demonstrated a negative correlation with these two parameters.Among the different weave structures evaluated,the 2/3 twill weave exhibited optimal UV protection and moisture permeability.Conversely,the 5-end satin weave demonstrated the most favorable contact cool feeling.
