Effect of Surface Modification on Ink-jet Printing of Cotton and Polyamide Fabrics
In order to improve the pattern effect of ink-jet printed cotton/polyamide fabric,the sodium alginate(SA)and dodecyl trimethyl ammonium chloride(DTAC)were used in the pretreatment process of cotton/polyamide fabric,and the color parameters of ink-jet printed fabric were tested.The effects of SA and DTAC modification on apparent color depth,graphic printing clarity,color fastness and mechanical properties of cotton/polyamide fabrics were analyzed.The results show that compared with SA pretreated fabric,the introduction of DTAC increases the apparent color depth and pattern clarity of cotton/polyamide fabric,improves the anti-seepage effect,but has no significant changes in color fastness and breaking strength.After DTAC modification,the modifier forms a film on the surface of cotton/polyamide fabric,which fills the pores between fibers.More reactive dyes can be covalently combined with fibers to improve the color depth and clarity of inkjet printing patterns.
