The Effect of N,N-dimethylamylamine on the Properties of Reactive Dye Fixing Agent

Diallyl dimethyl ammonium chloride (DMDAAC) is very popular cationic monomer that is used to synthesize color-fixing agent. But this kind of fixing agent has some drawbacks. This paper reports to minimize those drawbacks by co-polymerizing with N,N-dimethylamylamine (DMAA). The effect was studied by varying the amount of DMAA with respect to main monomer DMDAAC. Also the effect of APS was observed on the polymer properties. The best polymer was found with DMDAAC and DMAA 61% and 1% respectively where the amount of APS was 0.5%. The synthesized agents were applied according to the industrial procedure on cotton woven fabric dyed with reactive dye. Color fastness to wash, color fastness to dry wet rub, change in K/S, lightness DE and overall color differences DE were observed to evaluate the synthesized agents

Comparative Analysis among Different ZnO Nanoparticles Synthesized by Different Techniques

Semiconductor oxides were synthesized and systematically examined on 100 % cotton fabric to optimize the properties. Nano-technology is employed in this research work to form nanoparticles of semi-conductor oxides. Four samples were synthesized by using different methods and dyed to find the effective one. Different characterization techniques are used to characterize nanoparticles e.g. X-ray powder diffractometer, Energy dispersive X-ray spectroscope (EDS, EDX or EDXRF) and SEM images. By examining diffraction pattern and SEM images homogeneity, crystalline phase, transparent finishing process and unit cell dimensions are found. ZnO-3 (sample 3) (TEA 0.025M) treated cotton is revealed to have unique properties and implied a transparent finishing process

The Influence of Annealing Process on Crystallinity and Structural Properties of Cotton/Spandex Fabric

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 140°C 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
