Natural dyes fromEucalyptusleaf extract, quercetin, rutin, and tannin were applied to silk fabric by pad-batch and pad-dry techniques under different conditions. Ferrous sulfate was used as a mordant. The dyeing properties were evaluated by measuringK/SandCIELABvalues. In addition, the different fastness properties were evaluated. The effect of dyes at different concentration levels with respect to their colour strength was also studied.

The present study was undertaken to use flour of wild taro (ColocasiaEsculenta (L.) Schott) as a resist printing paste for silk fabric and using reactive dye as a dyestuffs. The K/S values, whiteness index and sharpness of printed silk fabric were studied. The washing, water, perspiration, light and rubbing fastness of the printed fabric was also evaluated. From the present work it can be concluded that the pattern at resist printing area of silk fabrics show sharpness and whiteness. Colour fastness to water and perspiration were ranging between poor to fair level. Printed fabric exhibited fair to good level in washing, rubbing and light fastness. The advantages of this product are environmental friendly that is non-toxic fumes; production cost is lower, instance application and creative process enhancement in textile production.

This research examined a dye extracted from eucalyptus leaves and its application to wool fabric using pad-batch and pad-dry techniques under various conditions. A wool fabric dyed in a solution containing eucalyptus extract gave a shade of pale yellowish brown except when it was dyed with FeSO 4 , resulting in a shade of dark grayish brown. The fastness properties of dyed fabrics ranged from good to excellent, while light fastness was fair to good. It was observed that the fabric had excellent ultraviolet protection factor (UPF) values. In addition, a darker colour provided by FeSO 4 gave better protection because of its higher UV absorption.

In the present study, natural dye from lac dye and various metallic salts have been used to identify the proper dyeing condition for attaining high quality natural dyeing along with imparting UV protection property to the dyed silk fabric. Silk fabrics dyed with lac extract showed a light pink shade, while those dyed with alum and stannous chloride pinkish-red colour. Silk substrates dyed with CuSO4gave a purple red colour, while those dyed with FeSO4had a reddish-gray colour. The fastness properties ranged from fair to good, while washing fastness was poor level. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between very good and excellent for the silk fabric.

This research was concerned with dye extraction from the bark ofGarcinia Dulcis(Roxb.) Kurz and with the application of this dye for silk fabric dyeing by the pad-dry process. Silk fabrics dyed withGarcinia Dulcis(Roxb.) Kurz bark extract showed a pale yellow shade, while those dyed with alum and stannous chloride bright yellow and light yellow colour, respectively. Silk substrates dyed with CuSO4gave a yellowishgreen colour, while those dyed with FeSO4had a dark brown colour. The colour fastness to rubbing after dyeing the silk fabric treated with the mordant was investigated, the results of which showed fair to good fastness. The results confirmed that natural dyes fromGarcinia Dulcis(Roxb.) Kurz bark extract have potential applications for fabric dyeing and producing ultraviolet (UV) protective silk fabric.

Thermal property is an importance factor of quick dry inner wears. This study aims to evaluate the thermal property of women’s quick dry inner wears in the market with different market position (Brand A: online brand; Brand B: general market and Brand C: youth market). The thermal property studied in this paper included (i) thermal conductivity and (ii) Q-max value (warm/cool feeling). The thermal conductivity and Q-max values were measured according to the standard of KES-F7. Thermal conductivity analysis showed that Brand B was the optimal product, while Q-max results indicated that both Brand B and Brand A had the best product in terms of quick dry property.
