Polyester fabrics are usually difficult in dyeing deeply due to their dense structure and high surface refractive index, and deepening finishing is an effective method to obtain dark polyester fabrics. In this article, octamethyl cyclotetrasiloxane (D 4 ), 1,3,5-tris (3,3,3-trifluoropropyl)-methylcyclotrisiloxane (D 3 F), and silane coupling agent KH-902 were used as main monomers to synthesize organic fluorosilicone, and further to prepare cationic organofluorosilicone (COFS) and COFS darkening agent. FTIR and 1 H-NMR were used to characterize the structure of synthetic products. The finishing experiments confirmed that COFS darkening agent had good shade darkening on dyed polyester fabrics with small color change. The optimum conditions of deepening finishing were COFS darkening agent concentration of 20%, the pick-up of 85%, and the curing temperature of 180 C. After finishing, the dyed fabric had no lowering effect on color fastness, all at grade 4 or above.

“…5,25,29 It should be noted that the commercial disperse dyes utilised for PLA coloration were actually developed for PET fibre coloration. [30][31][32][33] In this study, heterocyclic disazo disperse dyes, synthesised in our previous work, 34 were applied to PLA and PET fibre fabrics to examine the performance of such novel dyes. The dyeing performances of all synthesised dyes on both fabrics were compared according to their exhaustion, colour, and colour fastness performances.…”

Poly(lactic acid) (PLA) is the first melt-processable, renewable, sustainable and biodegradable natural-based synthetic fibre. It has a broad range of uses and combines ecological advantages with outstanding performance in textiles. PLA fibre, as an aliphatic polyester, can be dyed with disperse dyes. Apart from the limited number of commercial disperse dyes, disperse dye exhaustion on PLA is generally lower than that on poly(ethylene terephthalate) (PET). In this study, new heterocyclic disazo disperse dyes, substituted with methyl, nitro and chloro groups at their ortho-, metaand para-positions, synthesised in our previous study, were applied to PLA and PET fibres to examine their dyeing performance, and colour fastness and dye exhaustion properties. Different shades of yellow, orange, reddish brown and brown were obtained. Most of the synthesised novel heterocyclic disazo disperse dyes exhibited good build-up properties with high K/S levels on both fibres. Para-bonding substituent provided higher K/S values than meta-and ortho-positions for-NO 2 and-Cl substituents for both fibres. Overall, the most synthesised novel heterocyclic disazo disperse dyes in this study exhibited good build-up properties with high K/S, exhaustion and wet fastness levels on both PLA and PET fibres.

“…Different classes of dyes according to their application on the fibers are known long time ago [1,2], while reactive dyes for cotton dyeing and disperse dyes for synthetic fibers such as polyester fabric are the most common classes [3][4][5][6][7][8]. Although disperse dyes can be used for dyeing of nylon fiber, but the use of disperse dyes are not common and have some limitation in nylon dyeing because of their week build up and its low fastness characters.…”

Synthesis and application of new reactive disperse dyes based on isatin derivatives and their Antibacterial activity

et al. 2019

View full text Add to dashboard Cite

A NEW two reactive disperse dyes based on a hybrid structure of isatin and benzanthrone or anthraquinone via 1, 3, 5 triazine spacer were prepared. The prepared compounds were characterized by 1 H-NMR, mass spectrometry and elemental analysis. The UV/vis absorption spectra and emission spectra were measured in N, N-dimethylformamide (DMF) solution at room temperature, the effects of substituent's on the emission spectra of these compounds were interpreted. The dyeing application of the prepared dyes on wool and polyamide-6 fabrics at various concentrations of dye and different pH were investigated as well as the exhaustion and dye fixation were studied. The antibacterial activity of the prepared reactive disperse dyes were studied against different kind of bacteria such as Staphylococcus aureus (Gram-positive bacteria) and Escherichia coli (Gram-negative bacteria). The antibacterial affinity of the prepared dyes was exhibit a significant effect compared with selected antibiotics as reference standard. The fastness properties of the dyed fabrics were studied which showing excellent wash fastness, rubbing and perspiration fastness as well as high stability to light.
