Abstract Cotton fabrics were treated with gelatin to improved their dyeability, color
strength toward cochineal dye. Gelatin were used as the protein. Gelatin is containing a
large number of hydrophilic groups. Pad-dry-cure method was used for the treatment
process(10g/L concentration). The scanning electron micrograph showed the gelatin was
deposited on the surface of cotton. Pretreated fabrics were mordanted with 10%(owf)
alum. Then the fabrics were dyed with cochineal. Compared with original cotton fabric
the K/S value with cochineal dyes was significantly improved on gelatin modified cotton.
Treating cotton with 10g/L concentration gelatin offered higher cochineal adsorption. The
dyeability of pH 4 yielded the highest color strength. In dyebaths of a ratio of ethanol and
water such as; 10:0, 9:1, 8:2, 7:3, 6:4, 5:5, 4:6, 3:7, 2:8, 1:9, 0:10, fabrics were dyed.
The ratio of ethanol and water had powerful effects on solution polarity. Cochineal dye
uptake showed maximum value, when the proportion of ethanol and water was 9:1. Dyeing
at increased temperatures and with increased time resulted in higher dye uptake and
reddish-purple color(5RP). The washing fastness was 1-2grade, and the fastness to light
was 2-3grade. |
