| Outline of Final Research Achievements |
Utilization of vegetable wastes was explored for 1) deep color dyeing, 2) dyeing with practical fastness, 3) dyeing giving deodorization function. Cloths of wool(w), silk(s), nylon(n) and cotton(c) were dyed(d), mordant dyed(md), duplicate dyed(dd), and duplicate mordanted(dm).
Results：Dyeing of extracted Chlorophyll md with copper(II) chloride ; Pueraria lobata (w, md, deep color),waste of green tea (w, s, n, c. md light yellow), Pueraria (w, md light green), and golden rod (s,c, md, dark green). Quelcetin (skin of onion)(n, md, light brown , fastness grade 4), (s,deep brown with the grade 3-4),(n, light yellow with the grade 4),゜(c. light yellow with the grade 3). 3) w cloth dyed with extracts of the skin of Japanese persimmon or outer peel of nable orange, showed enhanced deodorization of ammonia. It seems that certain acidic components contained in these skins do work for the protonation and fixation of ammonia.
