Naturally Colored Organic Cotton (NaCOC)의 시감성 평가
- Naturally Colored Organic Cotton (NaCOC)의 시감성 평가
- Date Issued
- In parallel to the social trend of green consumerism and wellbeing, the demand for naturally colored organic cotton (NaCOC) continually increases in the textile and clothing industry. The present study examined the reliability of a visual sensibility evaluation method and the effects of NaCOC color, scouring, and evaluator’s age on the visual sensibility of NaCOC. A test-retest regime being administered, two age groups (20s & 30s
40s & 50s) of female evaluators rated three color sets of NaCOC specimens (ivory, green, and coyote brown) treated by two chemical scouring (Na2CO3 and NaOH) and two bioscouring (enzyme and boiling water) methods using 7-point scales of nine visual sensibilities (bright-dark
and luxurious-cheap). The bipolar visual sensibility adjectives were selected for the visual sensibility evaluation of NaCOC from a review of related studies. The inter-rater variability (grand average of SD = 1.08) of the sensibility evaluation method was found about 1.4 times the corresponding intra-rater variability (grand average of SD = 0.76). Between-group agreement (20s & 30s vs. 40s & 50s) for visual sensibilities was the largest (mean = .77) among overall agreement (mean = .48) & within-group agreement (mean = .53 for 20s & 30s
.54 for 40s & 50s). Preferred scouring methods for the cotton colors and age groups were identified for each visual sensibility scale. Lastly, color emotion models were developed to study the relationship between colors and visual sensibilities. The present study demonstrated that a bioscouring method can replace the traditional chemical methods for selected visual sensibilities.
