Dyeing the cotton with natural colors from Karonda (Carissa Carandas Linn.) powder

Abstract

This study has objectives to 1) study the dyeing of cotton with natural colors from Karonda (Carissa carandas Linn.) powder, 2) design products from cotton dyed with Karonda (Carissa carandas Linn.) powder, and 3) study the satisfaction of questionees towards a product prototype. The methodology consists of three phases. Phase 1 is to study the dyeing by preparing dyeing water from 50 ml of water and three different weights of Karonda (Carissa carandas Linn.) powder which are 1, 3, and 5 g. Each concentration is tested using 30, 60, and 90 mins. Then, they are analyzed using Ducan’s multiple tests. Color values are measured using CLE LAB. Phase 2 is to design products from cotton dyed with Karonda (Carissa carandas Linn.) powder using the tie-dye method and phase 3 is to evaluate the satisfaction of questionees towards a product prototype. Tools are interview form, product draft, and satisfaction questionnaires. Samples are 100 persons who evaluate the satisfaction towards product prototype who are selected using accidental sampling. Data is analyzed using frequency, percentage, mean, and standard deviation. Results show that dyeing using Karonda (Carissa carandas Linn.) powder at the concentration of 5 g per 50 ml of water for 90 mins provides the lowest lightness (L) of 53.51^a0.09 (highest color intensity), a^* of 15.44^b0.99 representing red adhesion, and b^* of 9.86^c0.02. For the design and satisfaction evaluation towards the bag prototype consisting of models A, B, and C, the overall satisfaction is high.
