To prepare the surface layers materials of the disinfected adsorbent dry towel with both good mechanical properties and conductivity,the surface materials of the disinfected adsorbent dry towel was prepared by mixing viscose fibers and ES fibers through the hot rolled nonwoven reinforcement process.The effects of fiber mixing ratio and hot rolling temperature on mechanical properties and conductivity of the material were investigated by single factor test.The results showed that the mechanical properties and conductivity of the materials were significantly affected by fiber mixing ratio and hot rolling temperature.The optimized process parameters were mass ratio of viscose fiber to ES fiber at 20/80 and hot rolling temperature at 135℃.The longitudinal and transverse breaking strengths of the surface materials of the hot rolled disinfected adsorbent dry towel prepared with optimized process parameters were 88.16 N and 36.82 N,respectively,with the absorption rate of 751%,the diffusion length of 18.1 cm,a soaking time of the permeable surface of 2.25 s,and the absorption rates of the upper and lower layers were 26.19%/s and 65.61%/s,the diffusion velocities of the upper and lower layers were 3.96 mm/s and 6.54 mm/s,respectively,and the unidirectional transfer index was 962,which had good mechanical properties and conductivity.
