Microwave-assisted coating of silver nanoparticles on bamboo Rayon Fabrics modified with poly(diallyldimethylammonium chloride)
Cellulose, 2016Co-Authors: Linghui Peng, Xiang WangAbstract:Silver nanoparticles were coated on bamboo Rayon Fabrics (Fabrics made from filaments of dissolved and regenerated bamboo pulp fibers) modified with poly(diallyldimethylammonium chloride) (PDDA) under microwave radiation. The silver nanoparticle coated bamboo Rayon Fabrics modified with PDDA were characterized by fourier transform infrared spectroscopy, X-ray diffraction, energy dispersive X-ray spectroscopy, atomic force microscope and scanning electron microscope. Color properties, ultraviolet (UV) protection, softness and contact angle of the silver nanoparticle coated bamboo Rayon Fabrics were evaluated. The results show that PDDA is successfully modified on the bamboo Rayon fabric. Compared with the bamboo Rayon Fabrics without PDDA modification, more silver nanoparticles are coated on the bamboo Rayon Fabrics modified with the PDDA. In addition, the bamboo Rayon fabric modified with PDDA is evenly covered with silver nanoparticles. The silver nanoparticle coated bamboo Rayon fabric modified with PDDA shows the excellent UV protection with UPF of 223.88 and the hydrophobic property with contact angle of 127°. PDDA modification improves the adhesive strength between silver coating and bamboo Rayon fabric.

Radiation Induced Grafting of Viscose Rayon Fabrics with Some Acrylic Acid Derivatives and Styrene
2017Co-Authors: Mahmoud Barakat Foad Ahmed Barakat, Kariman Mohame El-salmawy, Abdel-hamid Hussein ZahranAbstract:Radiation induced grafting of viscose Rayon Fabrics, consisting mainly of cellulose fibers, with some acrylic acid derivatives, namely methyl acrylate, acrylamide and acrylonitrile, and also styrene, has been studied. The resultant graft yields have been determined as a function of the applied different experimental parameters. The impact of the graft yields on the physicochemical properties of viscose Rayon Fabrics such as swelling, moisture absorption, tensile strength, elongation at break, crease recovery angle and also dyeing ability of the grafted Fabrics, has been also studied.

radiation induced grafting of acrylic acid onto viscose Rayon Fabrics and its after effects
Open Journal of Polymer Chemistry, 2016Co-Authors: M F Barakat, K M Elsalmawy, Abdel-hamid Hussein ZahranAbstract:Radiation induced grafting of various polymers with different monomers proved to be an attractive means to modify the physical or chemical properties of polymeric materials or textile Fabrics. In the present work, radiation induced grafting of viscose Rayon Fabrics, consisting mainly of cellulose fibers, with acrylic acid monomer has been carried out. The grafting yields have been thoroughly studied as a function of different applied experimental parameters. The impact of the graft yield on the physical properties of the Fabrics such as tensile strength, elongation, swelling, moisture absorption, crease recovery angle and also the dyeing properties of the Fabrics has been studied. The effect of increasing the contact time of the fabric and monomer solution, at room temperature, after stopping irradiation has been studied in detail as well as the effect of temperature on the irradiated samples also after stopping irradiation. The best grafting yield was obtained on irradiating viscose Rayon fabric in methanol-water solvent containing acrylic acid monomer, at a dose 20 kGys, then heating for 7 hours at 80℃ and finally keeping the samples at room temperature for about 20 hours. That treatment significantly increased the final graft yield.

medical textiles based on viscose Rayon Fabrics coated with chitosan encapsulated iodine antibacterial and antioxidant properties
Textile Research Journal, 2018Co-Authors: Lidija Fras Zemljic, Zdenka Persin, Olivera Sauperl, Andreja Rudolf, Mirjana KosticAbstract:Adsorption of chitosan nanoparticles with embedded iodine was implemented onto pristine and oxidized cellulose viscose Fabrics in order to introduce antimicrobial and antioxidative functionalization. The adsorption capacity, charging behavior and electrokinetic response of differently functionalized viscose at different pH values were analyzed by determining their zeta potential. Desorption studies, besides zeta potential measurements, were supported by polyelectrolyte titration. Finally, the antimicrobial properties were evaluated by the standard ASTM E2149 method, whilst antioxidative properties were determined by 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical cation decolorization assay. It was found that the oxidation of viscose Fabrics further modified by chitosan–iodine nanoparticles dispersion was a very promising functionalization process, providing good coating stability along with antimicrobial and antioxidant properties.

dyeability and functionality of Rayon Fabrics treated with persimmon juice
Fashion & Textile Research Journal, 2015Co-Authors: Jungsook BaeAbstract:The results of the analysis of dyed Rayon Fabrics treated with persimmon juice by padding are as follows. Rayon Fabrics were dyed repeatedly with persimmon juice by a padding mangle for the development of dyeability. The merits of padding-based dyeing were easier color reproduction (versus traditional hand dyeing) of hard to obtain colors and color fastness to light and laundering. The add on weight increased with the number of padding times, and the color of the dyed Fabrics had red-yellow colors with low brightness and high chromatic colors. Properties of Fabrics treated with persimmon juice were: level of light resistance, perspiration fastness levels, rubbing fastness, and washing fastness levels. Dyed Fabrics exposed to UV light have a deep yellow-red color that increased lightness and darken when exposed to sunlight. Rayon Fabrics of a treated premordant indicated strong yellow colors, especially Fabrics with Fe mordant indicated greenish red-yellow colors. The direction of the weft and warp increased and improved water-repellent qualities that increased with the number of dyeing padding times and persimmon juice; however, there was less anti-crease resistance. In addition, Fabrics had good antibacterial activity and deodorization.

mechanical properties of Rayon Fabrics dyed with persimmon juice
Fashion & Textile Research Journal, 2013Co-Authors: Jungsook BaeAbstract:For development of dyeability, the Rayon Fabrics were dyed repeatedly with persimmon juice by padding man- gle. The merit of padding-based dyeing was easier color reproduction over traditional hand dyeing where various colors and color fastness to light and laundering are hard to obtain. We evaluated the mechanical properties and hand value by Kawabata Evaluation system for dyed Rayon Fabrics. The results obtained from this study were as follows. With the increase of repeating padding times of dyeing, the linearity load- extension curve and tensile energy per unit length of the Rayon Fabrics were increased, but the tensile resilience of Fabrics were decreased. The value of shear stiffness and shear hysteresis were increased. Also compression resilience and linearity of compression thickness were increased. The Rayon Fabrics dyed with persimmon juice had shown the thickness and weight increase as the number of padding increase. As repeating times of dyeing with persimmon juice were increased, among the 6 hand values, the item of koshi(stiffness) and Hari(anti-drape stiffness),fukurami(fullness and softness) were increased. while Shinayakasa (flexibility with soft feel- ing) and Shari(crispness) were greately decreased. The amount of coated persimmon juice on the surface of the fabric was gradually increased as the padding times of dyeing.
