ABSTRACT
Direct dyes still represent an important class of dye for use on cellulose fiber, because of the ease of application and low cost. The present study was aimed at development of microbial resistant cotton using antibacterial agent in dyeing process through exhaustion method. Cetyl tri-methyl ammonium bromide (CTAB), as a cationic antibacterial agent, was used in dyeing of cotton fabric with direct dyes. The antibacterial activities, washing fastness, light fastness, and bending length of the treated fabrics were investigated and the results discussed. To reveal the antibacterial properties of the treated samples, the zone of inhibition was measured for S. aureus and E. coli. Finally, the fabric dyed with 5% NaCl, 5% CTAB, and 2% Direct Blue 86 indicated good antibacterial properties against S. aureus; however, the dyed fabric with 5% NaCl, 1% CTAB, and 2% Direct Blue 86 showed more suitable antibacterial properties against E. coli in compare to other samples. Further, the dyed cotton fabric along with CTAB prevented S. aureus growth more than E. coli.
摘要
论述了DRF-3型摩擦纺棉纱的结构-性能关系，其芯为单捻棉环纱，鞘由同一棉纤维制成。用示踪纤维研究了单纤维短纤纱在DRF纺纱过程中的结构变化。单纱的物理性能，即其计数、捻度倍数和捻度方向，以及在纺纱试验中所用的鞘纤维的比例与最终的纱线力学性能有着密切的关系。单纱捻度方向的影响最显著，除了单纱捻度倍增量外，包芯纱的比例很大程度上决定了芯纱的拉伸性能。F纱线呈反比关系，在断裂的具体工作方面比较合适。论述了DRF-3型摩擦纺棉纱的结构-性能关系，其芯为单捻棉环纱，鞘由同一棉纤维制成。用示踪纤维研究了单纤维短纤纱在DRF纺纱过程中的结构变化。单纱的物理性能，即其计数、捻度倍数和捻度方向，以及在纺纱试验中所用的鞘纤维的比例与最终的纱线力学性能有着密切的关系。单纱捻度方向的影响最显著，除了单纱捻度倍增量外，包芯纱的比例很大程度上决定了芯纱的拉伸性能。F纱线呈反比关系，在断裂的具体工作方面比较合适。
