The purpose of this study is to provide the dyeing and physical characteristics of napped knit fabrics composed of latent crimped yarn. The K/S values, dyeing fastness, thickness, bulkiness, and shrinkage characteristics of three knit fabrics were investigated. The original knit fabric (SK) was composed of 1ply latent crimped yarn (75/36) in the ground and PET DTY (70/100) in the pile loop, in order of napped process the napped knit fabric (SN) was napped SK fabric. In order to compare of latent crimped yarn content, the last knit fabric (DN) was napped 2ply latent crimped yarn were included in the same structure of SK. Dyeability of three knit fabrics was similar but the shrinkage properties of DN fabric were significant different. The bulkiness shows a tendency to increase the bulkiness as increasing the dyeing temperature, and the bulkiness of the SN was higher because of the napping process and optimal content of latent crimped yarn.
