Effects of Difference in Weave on the Visual Evaluation of White Silk Fabrics and Black Ones.

The effectiveness of two conventional techniques to evaluate the surface qualities of silk fabrics, the ranking method and the paired-comparison method, was studied.The mutual correlation and the effects of the dif ferences in color and weave on the accuracy of the evaluation were analyzed.Eight types of silk fabrics were compared; each type had the same material, weave density, and count of the weaving yarns, but each had a differ ent weave.They were visually evaluated as to luster, quality of texture, and attractiveness for two cases: in one, the sample were white, and in the other, they were dyed black.The obtained data showed that the correlation be tween the two techniques was high.For both sample colors, the paired-comparison method was somewhat superior to the other in the accuracy of determination.For some of the items compared (luster and attractiveness), evalua tion was appreciably affected by color, but for others (surface roughness and thickness), this was not so.
