Abstract

This study investigated the effect of organic alternative scouring agents on structure of cotton/polyester blend fabric. A structural modification for a cellulose/polyester blend has been carried out using (COOH)2, CH3COOH and CH3CH2OH alternative scouring agents and NaOH was used as control. The scoured fabrics were then subjected to structural analysis using X-ray diffraction in order to expose the possible modifications on the pretreated fabrics. The samples showed possibilities of being highly competitive with the conventional agent. These inferences were drawn from the difference in the crystallinity index of scoured samples (10.10-60.03%), the crystallite size of scoured samples (6-9 nm) in the crystalline region (6-11 nm), in the amorphous region, inter-planar spacing of the scoured samples (0.340-0.350 nm) of the crystalline region and (0.360-0.390 nm) of the amorphous region of sample and number of crystalline planes of the scoured sample is (3-10) of the cellulose/polyester blend fabric samples via X-ray diffraction studies.  Keywords; Cellulose, Fabric, Organic, Polyester, Scouring Agents

Highlights

Cellulose/polyester blend fabric is the combination of natural and synthetic fabrics so that the excellent quality and properties are emphasis and a poor quality and properties are minimize
This work investigated structural modification changes on cellulose/polyester blend fabrics by the organic alternative scouring agents and subjected to structural analysis using X-ray diffraction in order to elucidate the possible modifications on the structures of the pretreated fabrics
Structural modification and certain degree of influence were observed in the X-ray diffraction pattern of the cellulose/polyester blend scoured with (COOH)2, the findings showed that cellulose/polyester blend fabric scoured with (COOH)2 might possess good dyeing

Summary

MATERIALS AND METHODS

Sample collection and preparation: The sample 35%/65% of cellulose/polyester blend fabric was purchased from Central Market Bauchi, Bauchi State, Nigeria. Scouring process (alternative scouring agents): Five separate beakers each containing equal volumes of 1 %, 2 %, 3 %, 4 % and 5 % NaOH solution were boiled for 5 minutes and equal numbers of 10 cm by 10 cm pieces of fabrics were immersed into each of the beaker. 1% sodium hydroxide solution or 1% acetic acid was used to neutralize the different scouring agents (Boryo et al, 2013). The sodium chlorite solution was boiled on a hot plate for 5 minutes in a beaker, and the scoured fabric was immersed in the solution and allowed to boil for 3 hours at a temperature of 75oC after which it was washed in a hot water, and neutralized with 5% acetic acid, washed with 2% detergent solution and rinsed with cold water and dried in the laboratory at room temperature for 45 minutes. Where; λ is the X-ray wavelength (0.154 nm), β is the angular width at half maximum intensity determine with the aid of Gaussian fit of the peaks on the diffractograms of the samples and θ is the Bragg angle
