Abstract

The dyeings of cotton and silk fabric with Laurus tree extracts were investigated. The colorant was extracted with distilled water at $100^{\circ}C$ for lh. Dyeability(K/S), color fastness and antibacterial property of cotton and silk fabric were tested under conditions of various time, temperature, concentration, repeat-number of dyeing and mordants. The characteristics of dyeings Laurus extracts were figured out by K/S and CIELab values and color-fastness test was estimated in terms of wash fastness and light fastness. The maximum wavelength of spectrum was 670nm. The K/S value of cotton and silk fabric increased with increasing dyeing time and the exhaustion was saturated in 90min. Optical dyeing temperatures of cotton and silk fabrics were $60^{\circ}C$ and $80^{\circ}C$, respectively. The mordant effect on cotton fabric was achieved using Fe mordant. On the other hand, the mordant effect on silk fabric was obtained using Fe and Cu mordants. The wash fastness of cotton fabric was higher than that of silk fabric. Antibacterial property of silk dyeing was greater than that of cotton dyeing. In addition, the excellent antibacterial effect was imparted by Fe-post mordant method.
