dc.description.abstract | The purpose of this research was to study the dyeing polyamide/elastane
fabric with natural indigo, using exhaustion dyeing process. The effects from the
concentration of the natural indigo dye, thiourea dioxide and sodium hydroxide were
investigated. The colour of each dyed material was investigated in term of the
CIELAB (L*, a* and b*) and K/S value. The color fastness to washing, rubbing,
perspirdation, light, water, sea water and chlorinated water of the dyed samples was
determined. The bursting strengrh of dyed polyamide/elastane was evaluated. The
best vatting condition was at 50 ̊C for 30 minutes. The optimal formula of dyeing
polyamide/elastane fabric using natural indigo was prepared by mixing 200 g/L
natural indigo paste, 60 g/L thiourea dioxide, 1 g/L sodium hydroxide. The fabric
dyed in the solution of indigo vatting a shade of dark blue colour. The color fastness
to light, washing, water, sea water, perspiration and chlorinated water were good to
very good. However, the rubbing fastness results showed fair level. The bursting
strength of dyed fabrics is less than the undyed fabric 3.1%. The optimal ratio of
discharge printing on polyamide/elastane fabric were compose of 70 % starch print
paste and 30 % discharging agent (KMnO4). The pattern design produced from these
combinations in the printing areas on fabrics showed an excellent standard of
printing quality. The results confirmed that natural indigo dyes have potential
applications in polyamide/elastane fabric dyeing and the dyed fabric can be used
produce women’s intimate apparel. | en_US |
