摘　　要：将GN与T分别以N/T 47/53、GN/T 47/53、GN/T 57/43、GN/T 85/15比例混合纺14.8 tex,捻系数358的紧密赛络纱,并织成橫密145/5 cm、平方米质量155 g/m^2相同规格纬平针针织物(其中N为普通锦纶,GN为含2.5‰生物质石墨烯的改性聚酰胺短纤,T为涤纶)。选用振荡烧瓶法定量评价四种GN/T织物对E.coli、S.aureus、C.albicans三种致病菌的抑菌活性。结果发现:GN比例越大,织物获得抑菌活性的时间越短;缩短接触时间,GN/T 57/43能在30 min内获得99%以上抑菌率,pH3～10条件下抑菌率达90%以上,洗涤50次后抑菌率达97.8%以上。得出在实际生产中为节约生产成本、提高纱线可纺性、获得较高抑菌活性的GN/T织物,综合选择57%的比例。GN and T were blended in a ratio of N/T 47/53, GN/T 47/53, GN/T 57/43, GN/T 85/15, respectively to spin 14.8 tex compact Siro yarns with the twist factor of 358, and woven into the weft plain stitch fabric with horizontal density of 145/5 cm and square meter quality of 155 g/m 2 (N is ordinary nylon;GN is modified polyamide short fiber with 2.5 ‰ biomass graphene, and T is polyester). The oscillating flask method was used to quantitatively evaluate the antibacterial activity of four GN/T fabrics against E. coli, S. aureus and C. albicans. The results showed that the larger the GN ratio, the shorter the time for the fabric to obtain antibacterial activity. After the contact time was shortened, GN/T 57/43 could obtain more than 99 % antibacterial rate within 30 min, and the antibacterial rate under pH3-10 conditions was more than 90 %. After washing 50 times, the antibacterial rate was over 97.8 %. Therefore, in the actual production, 57 % ratio should be chosen for GN/T fabrics in order to save production cost, improve yarn spinnability, and obtain high antibacterial activity.
