“…Chemical composition analysis: In the spectrum of Fig. 5(a) suggests the typical aspects of cellulose: a strong peak at 3418 cm -1 due to O-H stretching, a peak at 2,900 cm -1 due to C-H stretching and a broad absorption peak between 1,164 and 1,058 cm -1 which results from the contribution of more than a few functional groups, particularly C-C stretching, C-O stretching and C-O-C stretching [38]. The small peak at 1,642 cm -1 is due to partial oxidation of alcohol to carbonyl functional groups.…”

In this research, an attempt has been made to extract natural dye from Macadamia integrifolia, as a new source for cotton dyeing with good enough properties for potential commercial applications. Optimum extractions were observed with a sodium hydroxide as solvent at 60 °C, time 60 min and M:L was 1:20. The study of different factors effecting dyeability of cotton fabrics were acquired at following conditions: dye concentration 50 %, salt concentration 10 g/L, pH 8, 85 °C and 120 min. The colour strength (K/S) and fastness properties were found to be satisfactory in the post-mordant-processed fabric with the use of optimum mordant (M1 > M3 > M2) concentration of 3 %. Based on UV-visible spectra analysis, presence of lignin was confirmed on extract of aqueous Macadamia integrifolia. The chemical composition analysis was determined by Fourier transform infrared spectroscopy (FT-IR) and surface morphology of cotton fibers were investigated by scanning electron microscopy (SEM) for any changes on fiber. It is hoped that with analytical assay natural colourants can be tailored to access acrimonious functional ambit of synthetic dyes for the textile industries up to some extent, especially in case of the natural fibers colouration.

“…The crystallinity behaviour of the samples was determined by using X-ray diffractometer (Shimadzu XRD-6000). The functional groups of treated samples were determined using a Fourier transform infrared (FTIR) spectroscopy (Bruker, United Kingdom) at the wavenumber range 500-4000 cm -1 [12,13].…”

Abstract. This research aims to elucidate the crystallinity, structural and mechanical properties of cotton/spandex knitted fabric after conducting heat setting i.e., annealing process with optimized condition for the first time. Experimental results disclosed that, crystallinity index (CI) (%) of heat-treated cotton/spandex were increased with increased temperature and also mechanical properties i.e., tensile strength was improved as the temperature rose from 120 to 140ºC and decreased with augmenting temperature ranges, which is in good agreement with the findings of CI % through X-ray diffraction (XRD) patterns. The attendance of cellulose dehydration was further confirmed by Fourier transform infrared (FT-IR) spectra in order to observe the structural integrity.

Abstract. On this planet, many investigations are applied to switch conventional chemical cloth techniques via ecopleasant and economically attractive bioprocesses using enzymes. The present study offers an enzymatic washing system using enzyme (Cellzyme SPL H/C) for boosting the ultraviolet and antimicrobial undertaking of denim garments. Experimental results showed that the 4.0% o.w.f enzyme awareness furnished a greater UPF than the other concentrations and before washed. Results divulge that enzyme (Cellzyme SPL H/C) not handiest preserve the fabric surface from UV degradation but also performed extended degree of antibacterial endeavour in opposition to some species of bacteria that leading to act as a nice antibacterial agent on the denim materials. The enzyme washing healing diminished the skin hairiness and accelerated the skin evenness of the denim fibres as shown by means of SEM measurements.
