BTCA showed to be the best crease resist agent for crosslinking cotton fabric with SHP. In addition BTCA treatment offers higher tear/ tensile strength compared to fabrics treated with dimethylol dihydroxyethylene urea DMDHEU. FTIR/FT-RAMAN spectroscopies showed the presence intermolecular ester crosslinks in cotton fabrics treated with BTCA. Treatment of Jarosol solubilised sulphur dyed cotton fabrics with PAMA/BTCA and SHP resulted in a colour change of dyed fabrics because of the reductive nature SHP. Jarosol sulphur dyed cotton fabric treated BTCA/PAMA improved washfastness due to locking dye inside the fibres but light fastness didn’t change.}, keywords = {cotton,Crosslinking,Spectroscopy,Sulfur dye,Polyacrylic,CO,maleic acid,Butane tetracarboxylic acid}, url = {https://pccc.icrc.ac.ir/article_75819.html}, eprint = {https://pccc.icrc.ac.ir/article_75819_6fa086fab6cf6d69bb218ac156fd9607.pdf} } @article { author = {Samaei yekta, T. and Pouradam, M. and Ksiriha, S.

Cotton fabric was printed upon with three commercial cellulosic reactive dyes which are based on the similar chromophore and possess different numbers of reactive and anionic groups. Colour yield and absorbed dye fixation of the printed cotton were evaluated at various pHs. The ink-jet printing was carried out on a HP DeskJet 5150 printer at 1200dpi, and then the printed cotton fabrics were air dried and then put into a steamer to fix the reactive dye on to the cotton fabric. The results indicated that the absorbed dye fixation levels increased by decreasing the numbers of anionic groups and appeared to be dependent of reactive group’s numbers. All reactive dye based inks are demonstrating excellent to washing and dry/wet crocking colour fastness. The light fastness of each reactive dye based ink fixed to cotton fabrics was mordant.}, keywords = {reactive dye,Anionic,cotton,Ink,Jet,Printing}, url = {https://pccc.icrc.ac.ir/article_75817.html}, eprint = {https://pccc.icrc.ac.ir/article_75817_f950c900f20adbc5b3a19f987f3c2d57.pdf} } @article { author = {Poursaberi, T.}, title = {Magnetic removal of acid dyes from wastewater with ionic liquid linked-nanoparticles}, journal = {Progress in Color, Colorants and Coatings}, volume = {7}, number = {1}, pages = {27-38}, year = {2013}, publisher = {Institute for Color Science and Technology (ICST)}, issn = {2008-2134}, eissn = {2383-1790}, doi = {10.30509/pccc.2013.75815}, abstract = {The acid dyes are one of the most widely used commercial dyes used in the textile industries.
