dyeing and antimicrobial characteristics of chitosan treated wool fabrics with henna dye
Carbohydrate Polymers, 2009Co-Authors: V Giri R Dev, Jayarama Reddy Venugopal, S Sudha, G Deepika, Seeram RamakrishnaAbstract:Abstract Chitosan, a naturally available biopolymer which is now increasingly being used as a Functional Finish on textile substrates to impart antimicrobial characteristics and increase dye uptake of fabrics was applied on wool fabrics. Henna a natural dye with proven bactericidal properties was applied on wool fabrics along with chitosan to impart antimicrobial characteristics. The effect of chitosan application on the dyeing properties of wool fabrics was studied by measuring the K / S values of the treated substrates at various concentrations of chitosan and the dye. The antimicrobial properties of chitosan and natural dyes both when applied independently and collectively on fabrics were assessed. The results proved that the chitosan treated wool fabrics showed increase dye uptake of fabrics. The treated fabrics were found to be antimicrobial and the chitosan treatment enhances the antimicrobial characteristics of the dyes. Fastness properties of the applied Finish to washing, rubbing and perspiration have also been discussed.

multi Functional Finish of polyester and p c blend fabrics by corona discharge ii multiFunctional Finish
Textile Coloration and Finishing, 1997Co-Authors: Bang One Lee, Pyong Ki Pak, Joo Hong Yeo, Hwa Sun LeeAbstract:Plasma techniques permit modification of the surface layers of the substrate while maintaining its bulk properties. The use of plasma treatment on textile fibers and fabrics is very limited, however, the limitations, plasma treatments have been used to modify surface properties of textiles. In this study, multiFunctional Finish was performed by corona discharge technique for surface Functionalization. Electron spectroscopy for chemical analysis(ESCA) was used to determine the ratios of carbon, oxygen, nitrogen, and phosphor at a 20 sampling depth. K/S value and limiting oxygen index(LOI) value were used to obtain information on the effect of the Finished fabrics. The mechanism of the flame retardancy was analyzed by the thermogravimetry-and the residue number. In ESCA, relative N1s intensity increased in case of mixtrure. The flame retardancy of the polyester and polyester/cotton fabrics treated with JA-6034 and JA-6050 was found to be operative mainly in the condensed phase mechanism. The multiFunctional Finish was better effect for the post treated Finish agent.

multi Functional Finish of polyester and p c blend fabrics by corona discharge i flame retardant and sanitary Finish
Textile Coloration and Finishing, 1997Co-Authors: Bang One Lee, Pyong Ki Pak, Hyun Ja Lee, Hwa Sun LeeAbstract:This paper was carried out to introduce flame retardant and antibiotic properties to polyester(PET) and polyester/cotton(P/C) blend fabrics. PET and P/C blend fabrics were treated by a paddry-cure method in the aqueous solutions of the Finishing agents(JA 6034, JA 6050, DC-5700). The corona discharge technique was applied to increase the polar group of the polymer surface. The characteristics of the treated fabric were investigated by means of scanning electron microscope (SEM) and electron spectroscopy for chemical analysis(ESCA), and water penetration time, limiting Oxygen index(LOI), and K/S value were also measured. Wettability of the fabrics was increased considerably with the corona discharge treatment. ESCA was used to elucidate the surface chemical composition of the fabrics treated with the corona discharge. Relative Ols intensity increased and oxygen was incorporated in the form of -C-O-, -C=O, and O=C-O on the polymer surface. The current study indicated that corona discharge treatment was effective for modifying the polymer surface.
