| description |
This research focuses on the utilization of natural dyes based on Lawsonia Inermis,
Azadiractha Indica and Curcuma Longa coated with superhydrophobic coating on
cotton fabric. Natural dyes were used in this research and superhydrophobic coating
for self-cleaning of fabrics. The fine powder dye was divided into eight
concentrations which were 0.25 g/ml (A), 0.50 g/ml (B), 0.75 g/ml (C), 1.00 g/ml(D),
1.25 g/ml (E), 1.50 g/ml (F), 1.75 g/ml (G) and 2.00 g/ml (H). The method that
involved in this research was direct dyeing for Lawsonia Inermis, Azadirachta Indica
and Curcuma Longa dye for cotton fabric. Dyed cotton fabrics were coated with
superhydrophobic coating using spraying technique. The coated and uncoated dyed
cotton fabric was tested physically and mechanically. The F (1.50 g/ml) of dye
concentration of uncoated and coated fabrics of Lawsonia Inermis, Azadirachta
Indica and Curcuma Longa shows the highest physical and mechanical strength. The
coated dyed cotton fabric with the Lawsonia Inermis, Azadirachta Indica, Curcuma
Longa indicated 5 (excellent) for crocking test. The bursting strength for Lawsonia
Inermis was (17.07 kPa), Azadirachta Indica (17.09 kPa), Curcuma Longa (17.08
kPa). Then, the weight loss for abrasion test at 5,000 and 20,000 cycles for Lawsonia
Inermis were (2.41%, 2.51%), Azadirachta Indica (2.43%, 2.53%), Curcuma Longa
(2.46%, 2.56%). As a conclusion natural dyes based on Lawsonia Inermis,
Azadirachta Indica and Curcuma Longa can be used as an alternatives dyes in textile
industry. |
