Prepara.ion of conductive cotton fabrics, by polymeriza.ion of pyrrole in presence of FeCl3 as an oxidizing agent and tetraethylammonium p-toluene sulfonat (TEAp-TS) as a doping agent which in turn caused a reduction in the moisture regain of the substrate, resulted in production conductive cotton fabrics in laboratory scale. Factors affecting the properties of the fabrics were studied, such as ra.io between FeCl3 and TEAp-TS and pyrrole concentra.ion. Polypyrrole coated cotton fabrics were characterized by scanning electron microscopy (SEM) and Fourier transform-infrared (FT-iR) spectroscopy. Resistivity, weight gain, color strength, tensile strength and elonga.ion of the coated fabric with polypyrrol were monitored according to ASTM procedures. The results had shown that, the conductivity, weight gain, color strength, tensile strength and elonga.ion increase by increa.ing FeCl3, TEAp-TS and pyrrole concentra.ion. This is due to the increase of amount of the conductive polymer on the fabric surface. FeCl3 (0.25 M/L), TEAp-TS (0.125 M/L), pyrrole (0.3 M/L), temperature (25°C) and time (4 h) represented the most appropriate formula.ion for effecting polymerizing of pyrrole and anchoring on cotton fabrics.

Starch was polymerized with methacrylic a.id (MAA) to different magnitudes of poly (MAA) using potassium persulphate/sodium thiosulphate redox initia.ion system. The polymeriza.ion products are referred to as “composite”. The latter consists of poly (MAA)-starch graft copolymer, poly (MAA) in the form of homopolymer, oxidized starch brought about under the influence of the initiator and intact starch. At this end, the composite, the copolymer, and the untreated (na.ive) starch were subjected to carboxymethyla.ion under different conditions and the rheological properties of these starch—based on products before and after carboxymethyla.ion exa.ined. Results obtained disclosed that the susceptibility of these products toward carboxymethyla.ion follows the order: na.ive starch > Copolymer > composite. Meanwhile, these products exhibit non-Newtonian thixotropic beha.ior before carboxymethyla.ion;and their rheology signifies the order: Composite > copolymer > na.ive starch whereas after carboxymethyla.ion these products are characterized by non-Newtonian Pseudoplastic beha.ior. For a given rate of shear, the apparent viscosity follows the order: na.ive starch > composite > copolymer > carboxymethyl composite > carboxymethyl starch > carboxymethyl copolymer, in contrast with pseudoplasticity which reveals an opposite order. it was also shown that the apparent viscosity increases by increa.ing poly (MAA) in the copolymer and composite and that redrying of the copolymer and the composite after normal precipita.ion and drying causes a considerable enhancement in the apparent viscosity of these products.

Finishing using TiO2-nanosol treatment of cellulose acetate (CA) fabrics before and after the latter were pretreated with H2O2was undertaken with a view to impart unique properties to CA fabrics, notably, self-clea.ing. Finishing was performed as per the pad-dry-cure method. The finishing treatment involved dispersing the nano-sized TiO2particles in a mixture of water and ethylene glycol (1:1) and applica.ion of the dispersions to CA fabrics was made under a va.iety of conditions. Self clea.ing a.ility of the fabrics is favored by 1) increa.ing the concentra.ion of TiO2-nanosol to certain limit;2) prolonga.ion of curing time up to 15 second;3) raising the microwave power from 80% to 100% but with the certainty that power of 90% is the most proper. Besides, exposure time-to UV ra.ia.ion-up to 90 minutes is essential to have remarkable self clea.ing properties while keeping other technical properties, namely, strength, roughness and wetta.ility practically unaltered. incorpora.ion of binder in the finishing pad-bath helps sta.ilizing the deposition of TiO2 with excellent self-clea.ing. Pretreatment of CA fabrics with H2O2 is a pre requisite to guarantee excellent self-clea.ing a.ility. Thermofixa.ion and microwave fixa.ion produces fabrics with very comparable technical properties.

The present work aims at studying the effect of Ultra-Violet/Ozone (UV/O3) irra.ia.ion of cotton fabrics on their interaction with chitosan/citric a.id based formula.ion and, the onset of this on the a.ility of treated fabrics to remove heavy metal ions from their aqueous solutions. To achieve the goal, the cotton fabrics were preirra.iated for 90 minutes using UV/O3 as ra.ia.ion source. The irra.iated and the unirrda.iated cotton fabrics were submitted to finishing formula.ion consisting essentially of chitosan as a finishing agent and citric a.id as crosslinking agent in combina.ion with sodium hypophosphite (SHP) as a catalyst. Finishing formula.ion containing different concentra.ions of chitosan (0 - 4) along with citric a.id (8 g/l) and SHP (4 g/l) were used and the interaction of chitosan with the cotton fabric was assessed through nitrogen measurement. The preirra.iated and chemically finished fabrics vis-à-vis the unirrda.iated fabrics were exa.ined for metal ion removal. Results conclude that the preirra.iated cotton fabrics exhibit higher nitrogen content than the unirrda.iated fabrics. The same holds true for heavy metal removal, exemplified by Zn2+ and Cd2+ ions from their aqueous solutions. That is, preirra.iated fabrics containing chitosan display higher percent heavy metal removal than their unirrda.iated mates.
