Abstract
Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
Looks at the eighth published year of the ITCRR and the research, from far and near, involved in this. Muses on the fact that, though all the usual processes are to the fore, the downside part of the industry is garment making which is the least developed side. Posits that the manufacture of clothing needs to become more technologically advanced as does retailing. Closes by emphasising support for the community in all its efforts.

This study aims to deal with the dyeing of nylon-/cotton-blended fabric in one bath using direct and acid dyes.
Abstract
Purpose
This study aims to deal with the dyeing of nylon-/cotton-blended fabric in one bath using direct and acid dyes.
Design/methodology/approach
The cellulose in cotton/nylon-blended fabric was chemically modified using 3-chloro-2-hydroxypropyl tri-methyl ammonium chloride (CHPTAC) as cationizing agent to impart positive charge on the cellulose. The modified and unmodified blended fabrics were dyed in a single bath with direct and acid dyes under various concentrations of 0.5, 1, 2, 4 and 6 per cent on the weight of fabric by exhaust method. The dyeing of modified and unmodified fabrics was characterized through the properties such as K/S and colorfastness to washing, rubbing and light.
Findings
The modified fabric exhibited higher color yield, comparable rubbing fastness and good washing fastness.
Originality/value
The dye uptake was maximum in a single-bath dyeing process of nylon-/cotton-blended fabrics without electrolyte addition, which minimizes the impact of dyes on environment.

Abstract
Purpose
The purpose of this work was to modify the surface of parawood sawdust (Hevea brasiliensis) microcrystalline cellulose (PW-MCC) used as reinforcing agent in polypropylene composites with benzoyl chloride under a mechanochemistry process.
Design/methodology/approach
The acetylated PW-MCC was produced from heterogeneous condition using planetary ball mill process at a rotation speed of 400 rpm. Before the esterification reaction, PW-MCC was pre-treated with pyridine at 60°C for 1 h in order to penetrate and swell the cellulose structure. The optimum condition of esterified PW-MCC with various molar ratios of benzoyl chloride/anhydroglucose unit (AGU) was studied. The degree of substitution, functional group, thermal stability and morphology of esterified cellulose were characterized by 1H-nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analyzer (TGA) and scanning electron microscopy (SEM).
Findings
The functional group from FTIR confirmed that PW-MCC was successfully esterified with benzoyl chloride. The optimum condition which gave the maximum degree of substitution at 3.00 was achieved by using benzoyl chloride/AGU at 5 for 1 h. SEM analysis revealed that the modified PW-MCC surface became rougher than the unmodified PW-MCC surface. The polypropylene composites with 5-30 wt% PW-MCC and esterified PW-MCC were prepared without compatibilizer.
Originality/value
The composites with esterified PW-MCC enhanced water resistance and thermal stability when compared to composites with PW-MCC.

Abstract
Purpose
The purpose of this paper is to study some chemical reactions of viscose grade pulp (alpha cellulose around 96 per cent) prepared by preoxyacetic acid pulping of bagasse for the preparation of some cellulose derivatives.
Design/methodology/approach
Viscose grade pulp was prepared by using ecological chemicals. The viscose grade pulp was subjected to some chemical reactions (e.g. carboxymethylation, cyanoethylation and phosphorylation reactions). The pulping and bleaching which are two important stages involved in the complex process of converting fibrous raw material (bagasse) into viscose grade pulp are also investigated in this paper.
Findings
The viscose pulp prepared by peroxyacid pulping of bagasse was subjected to a number of chemical reactions such as: hydrogel and fibrous carboxymethyl cellulose; cyanoethyl cellulose, in which this cyanoethylcellulose (of gel properties) was prepared, the hydrophobic character of the cyanoethylcellulose was changed into hydrophilic character via hydrolysis by NaOH (2.5 per cent w/v) which converts some of the CN groups into COOH; and cellulose phosphate. Infrared spectroscopy of these derivatives was studied. New bands were observed at 3,120, 2,251, 1,200 and 980 cm−1 which characterised to groups, respectively.
Originality/value
The paper documents the preparation of some cellulose derivatives which have high water absorption and can be used as hydrogel materials such as carboxymethyl and hydrolysed cyanoethyl cellulose and ion exchange properties.
