Abstract: Choose the organic thermochromic compo site materials as thermochromic microcapsule core-material,Using and studying crystal violet lactone 、bisphenol A and tetradecyl alcohol as the components of compo site materials according to the need of textiles finishies. We analysed the structure and capability of the compo site materials and identified 1:4:70 as the optimal ratio of the compo site materials could suitable for discoloration gradient of textiles,lay the foundation for preparation of microcapsule and textiles finishies. The discoloration fabric as functional textile has a tremendous market potential,its could using discoloration dress、materials-show and prevent bogus marker。Thermochromic fabrics is the intelligent textile and colour changed following the temperature changes. Generally,the Thermochromic materials was encased by microcapsule and using the finishing technology pasted the microcapsule on the surface of fabrics,so the fabric could has the discoloration function. Currently,thermochromic materials have organic、inorganic and Liquid crystal materials. Study to thermochromic materials and achieved a organic thermochromic compo site material in this paper,using the compo site material as the core-material of thermochromic microcapsule for the discolouration fabric finishes.

Abstract: The dyeing and fastness properties of silk fabric dyed with natural dye extraction from the bark of Garcinia Dulcis (Roxb.) Kurz by the pad-batch process was studied. The effect of dyes at different mordant concentration levels on their colour strength was also investigated. Silk fabrics dyed with Garcinia 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 CuSO4 gave a yellowish green colour, while those dyed with FeSO4 had a dark brown colour. The fastness properties showed fair to good rating, whereas the colour fastness to perspiration was at a poor level.

Abstract: Cotton fabric samples were printed with pigment dye using warp yarn printing technique has been investigated. The color fastness was evaluated to testing in with washing, light, rubbing, water, and perspiration of the printed samples, the test were determined according to ISO 105-C06 A1S: 2010, ISO 105-B02: 1994, ISO 105-X12: 2001, ISO 105-E01: 2010, and ISO 105-E04: 2008 respectively. The results showed that the colour fastness to washing, water, and perspiration were in very good level whereas colour fastness to rubbing was in good. The results indicated that the properties of printed samples (handling and sharpness) were good to very good level.
