柞蚕丝针织汗布水分管理性能评价OA

Tussah silk fiber is a type of natural silk protein fiber with a flat ribbon-like structure.It has une-venly distributed micropores in its cross-section and micro-grooves on its longitudinal surface.This characteristic structure endows tussah silk with excellent moisture absorption and wicking properties,giving it application poten-tial in moisture management.In this paper,91/9 tussah silk/spandex knitted single jersey was taken as the re-search object.Multiple performance indicators during the moisture absorption,wicking,and moisture release sta-ges of textiles were selected and combined with the interface properties of the fabric surface to conduct compre-hensive evaluation.The results showed that the moisture absorption rate of the tussah silk knitted single jersey reached up to 360%,and its moisture regain was 8.9%;the wicking heights in the warp and weft directions were 4.43 cm and 6.40 cm,respectively,showing anisotropy;the average water drop spreading time was 28.2 s with a coefficient of variation of 35.6%,which was greatly affected by differences in fabric surface morphology;the moisture evaporation rate was only 0.0641 g/h.Although the fabric could not meet the quick-dry requirement,it exhibited good moisture absorption and wicking properties.
