The purpose of the study is to reduce the energy load of Cold pigment dyeing (CPD) process by minimizing process steps. As a representative effort in this direction, the current paper describes the effect of curing treatment on Cold pigment dyed garments considering different properties. Pretreatment of samples were done in the same bath and same method followed for both samples. In case of dyeing, two different methods i.e. existing (Pad-dry-cure) and experimental (pad-dry) were used to develop the samples. Prepared samples were evaluated in terms of CMC∆E value, color fastness properties, drape co-efficient, GSM, fabric strength and surface morphology respectively. Results of the study authenticate better output than the existing process by considering process time and energy savings. Color fastness value of the experimental sample offers comparatively better values than the existing process while other results are within range. Experimental process can reduce up to 6% processing ...

Treatment of 2-Mercaptothiazoline, 2-Mercaptobenzimidazole, 2-Mercapto-1- methylimidazole with [M2(CO)10] (M = Re and Mn) at ambient temperature in presence of decarbonylating reagent Me3NO give the complexes [Mn2(?-?2-C3H4NS2)2(CO)6] (1), [Re2(?-?2-C3H4NS2)2(CO)6] (2), [Mn2(?-?2-C7H5SN2)2(CO)6] (3), [Re2(?-?2- C7H5SN2)2(CO)6] (4), [Re2(?-?2-C4H5N2S)2(CO)6] (5) and [Re2(?1-C4H5N2SH)(CO)9] (6) respectively. All the compounds have been characterized by IR, 1H NMR and mass spectral data. The heterocyclic ligands are expected to be coordinated to two or single metal atom through the nitrogen and sulfur atoms or via only sulfur atom.DOI: http://dx.doi.org/10.3329/jbcs.v25i1.11775 Journal of Bangladesh Chemical Society, Vol. 25(1), 62-70, 2012>
