Purpose – Based on clarifying the structural difference between jade fibre and general polyester fibre, this paper aims to study the dyeing properties and dyeing adsorption mechanism of jade fibre with disperse dye and cationic dye. Design/methodology/approach – The chemical structure and microstructure of jade fibre were briefly explained comparing with ordinary polyester fibre. The dyeing rate curve and dyeing adsorption isotherm of disperse dyes and cationic dyes on jade fibre were, respectively, studied. The dyeing uptake, dyeing absorption mechanism, and the main dyeing process parameters were proposed. Findings – Jade fibre can be dyed with cationic dye and disperse dye. The suitable exhaust dyeing process is 110°C and 40 minutes for disperse dye, 100°C and 60 minutes for cationic dye. The dyeing uptake on jade fibre with both disperse dyes or cationic dyes is much higher than that on general polyester fibre and acrylic fibre, and the dyeing adsorption mechanism belongs to the combination of Langmuir and Nernst adsorption for disperse dyes and Langmuir adsorption for cationic dyes. Comparing with ordinary polyester fibre, jade fibre has the advantage of low temperature dyeing and reduced effluent, as is significant to energy-saving and emission reduction. Originality/value – Jade fibre is a new type of modified polyester fibre with the function of health protection and energy conservation. There are little technical data in the literature at present about the dyeing property of jade fibre.

The current article aims to synthesize some new arylazo-thiophenes for dyeing polyester fabrics and screen their antimicrobial activities. The new 4-arylazo-2-( N-pyrazolylcarboxamido)-thiophene dyes 4a–e were prepared by the reaction of 2-acetyl-2-arylazo-thioacetanilide derivative 1 with 2-chloro- N-(3-methyl-1 H-pyrazol-5-yl)acetamide derivative 2. The structures of these prepared analogues were established via Fourier-transform infrared and 1H/13C nuclear magnetic resonance spectra. The synthesized dyestuffs were applied to polyester fabrics after establishing the optimal dyeing conditions at 130 ºC, high pressure, 3% shade, and liquor ratio 20:1 at pH 5. Furthermore, the dyed fabrics obtained under these optimal conditions resulted in proper colorfastness toward washing, rubbing, sublimation and perspiration, and were adequate for light fastness. They showed respectable antibacterial effectiveness against two bacterial strains, Staphylococcus aureus (Gram-positive) and Salmonella typhimurium (Gram-negative) bacteria. The dyed fabric with dye 4d displayed the best antibacterial activities with percentage reduction of 88% and 76% against S. aureus and S. typhimurium bacteria, respectively.
