| Popis: | Silk/PLA mixture is a new textile material, and it combines the outstanding characteristics of silk and PLA fibers. During the wet process, this mixture is subjected to some problems owing to the poor resistance of PLA fiber to alkali. The silk component in this mixture can be dyed with acid dyes under acidic condition, and with reactive dyes under alkaline condition. In the present work, silk/PLA mixture was dyed with Everzol ED reactive dyes in the case of the use of sodium carbonate and sodium bicarbonate as alkalis for the fixation of dyes. The alkali dosage and dyeing temperature on the uptake of dyes by this mixture were discussed. Also, the dyeing rates, building-up properties and color fastness of reactive dyes were determined. It was found that Everzol ED reactive dyes exhibited good dyeing properties for silk/PLA mixture under weakly alkaline condition in the presence of sodium bicarbonate. |
