The Adsorption Character of Kapok Fiber and Reactive Dyeing Technology on Modified Kapok Fiber

The adsorption character of kapok fiber with direct dyes and the dyeing technology of cationic modified kapok fiber with reactive dyes were studied in this article. The results indicate that the optimal dyeing technique parameters for the cationic modified kapok fiber with the reactive dye Cibacron FN-R include 0.5~1% (o.w.f) of dyes, 15~20g·L^-1 of NaCl, and 2g·L^-1 of JFC with bath ratio of 1:50 at a dyeing temperature of 40°C for 30min. The dyed kapok fiber was fixed with 15~20g·L^-1 of Na₂CO₃ for 60min. As a result, the dye-uptake, fixation ratio, wash fastness, friction fastness, and K/S of cationic modified kapok fabric were enhanced by above technique.
