Chitosan Antimicrobial Chitosan / Cotton Blend Knit Dyeing Performance Based

Chitosan/cotton blended knitted fabric is a kind of antibacterial functional fabric, is widely used in underwear, socks and other products, with a wide range of applications. Although chitosan fibers have excellent antibacterial properties, but result in lower antibacterial properties in scouring and dyeing process.Comparing different blending ratio of chitosan paper/cotton knitted, When content of chitosan is more than5%,fabric is antimicrobial, and with content of chitosan increased blended knitted fabric antibacterial is improved.Research from actual production starting in improving blended fabric antibacterial properties on the basis of scouring and bleaching and dyeing process improvements:(1)scouring and bleaching process improvement after using mild neutral bio-scouring enzyme scouring-improved oxygen bleaching method to avoid acid is used, not only for the chitosan fiber damage, and blends of small antimicrobial effect and can greatly reduce environmental pollution.(2)Chitosan/cotton blended knitted fabric using reactive dyes, dye staining low relief, not only can improve the levelness, chitosan can reduce the loss of quality fabric with good color fastness, bursting strength, anti-bacterial and otherThis paper discusses the method of scouring and bleaching, dyeing method (isothermal heating method and the cold pad-batch method), dyeing process conditions (factors such as temperature, PH value, etc.), dyeing auxiliaries, dyes (reactive dyes and direct dyes) and surfactant Chitosan/antimicrobial effects of cotton knitted fabric on the final results of the process parameters used to provide basic data and then guide the actual production.
