Effect of Sol Treatment on Colorfastness of the Cotton Fabrics Dyed with Reactive Dyes
A novel sol used in textile finishing was prepared by sol-gel method with tetraethoxysilane and tetrabutyl titanate.The cotton fabrics were dyed with reactive dyes and treated by the sol with the process of double-padding followed by drying at 60℃ and curing at 160℃ for 3 min.The results about the fastness properties of the fabrics showed that the dry crocking fastness was improved by half a grade,and the fading percentage decreased by nearly 30.0％.In a treatment,the calculated sol weight gain was 5.4％,and the △E value of the fabric dyed with a reactive red dye decreased by 58.0％ after treated with the sol and exposed in the Xenotest for 120 h.The treatment with the sol had no obvious effect on the hue of the fabrics.These results indicated a favorable application performance using this sol.
