Sorption of Monoazo Dyes on Wool Fibers for Textile
An attempt has been made to characterize and to compare the structure, properties and mechanical behavior of popular Indian white wool fiber, black wool races and its blend. The XRD measurements reveal that Wool fibers of white, black wool races and blend are amorphous in nature. The amide-I band at 1700–1600 cm–1 is characteristic to the peptide C=O stretching reveals the information whether the carbonyl groups participate in the bonding and 1623 cm–1 for Amide-I band, which are characteristic peaks of wool fibers. In compare with pure wool fiber with its blend the additional peaks reflects at 1645 cm–1 for 1day and 1652 cm–1 which indicates the presence of Monoazo yellow in the fiber were identified using Fourier Transformation Infrared spectroscopy. The apparent diffusion coefficient is found to be 0.5122 × 10–7 cm2s–1 for monoazo diffused in wool and 0.5367 ×10–7 cm2s–1for monoazo diffused in blend. Hence these wool fibers and its blend can be used for textile fabrication.
