Features of Conventional Static and New Dynamic Drape Coefficients of Woven Silk Fabrics

摘要

Conventional static and new dynamic drape coefficients of "silk woven fabrics are examined precisely to distinguish those features of each classified fabric by its yarn structure using our regression equations. We find that Shantung has large values of static drape coefficient D_s and small node number n, revolving drape increase coefficient D_r, and dynamic drape coefficient with swinging motion D_d. Chirimen is characterized by large values of D_r and D_d. Georgette has small values of revolving drape coefficient at 200 rpm, D_(200). Habutae has relatively large values of D_s and small n, and Dechine has relatively large values of D_r and D_d, but Fujiginu has no peculiar features. The differences between Fujiginu, Dechine, and Georgette become clear from the discriminant analysis, using the five drape parameters as variables. New dynamic drape coefficients are more useful for characterizing each classified silk fabric.
