Novel Method for Preparation B-Cyclodextrin / Grafted Chitosan and it's Application
A noval technique for preparation of B-Cyclodextrin / grafted chitosan was carried out by reacting B-cyclodextrin citrate (B-CDC) with chitosan. B-cyclodextrin citrate (B-CDC) was synthesis by esterifying B-cyclodextrin with citric acid in...
The Preparation and Characterization of PP/ NanoAg Bicomponent Fiber
Polymer nanocomposites comprise a new class of material as the physical properties of polymers can be improved by incorporating nanoparticles. Also the inorganic-organic bicomponent nanocomposites have been studied recently due to their com...
Effect of Defuzzing methods on extent of preparation and dyeing of cotton fabrics
Three defuzzing methods, viz. singeing, neutral cellulose and acid – cellulose enzymes, have been applied to two woven cotton fabrics, to remove protruding fibres , prior to scouring and half – bleaching . The effects of theses methods on t...
The Return to Natural Dyeing Methods - Properties and Threats.
Nature in her unerring wisdom has provided colours. Designers and scientists tried to learn from nature the mysteries of colour. They accumulated this knowledge and use it to discover all shades and hues. Natural plants as a source of colou...
Recent Researches in Cotton Bleaching
Pretreatment processes of textiles continues to expand each year as older products and processes are replaced by the technological diffusion of novel products and innovative processes. One of the most important processes of pretreatment is...
Surface Area Estimation of Poly(vinyl alcohol) Microfibrillar Fibers by Dyeing
Ultrafine synthetic fibers have much usability such as artificial leather and high quality fabric. But these have also shortcomings in dyeing for it is difficult to dye in deep color. Recently, poly(vinyl alcohol) (PVA) microfibrillar fiber...
Exhaust Dyeing of Cellulosic Fabrics with Hot Brand Reactive Dyes at Mild Condition
The utilization pf triethylamine ( TEA ) , triethanolamine ( TEOHA ) or choline chloride ( CC ) as a co-catalyst along with Na 2Co3, NO2 SiO3 or Na 3PO4 as a traditional fixing agent in exhaust dyeing of mercerized cotton, viscose and linen...
Investigation Into The Effect of UV/Ozone Treatments On The Dyeing Properties of Natural Dyes on Natural fabrics
The effect of uv/ozone treatments for different periods on dyeing properties of three different natural fabrics, i.e. wool, silk, and cotton dyed with two natural dyes have been investigated. The results indicated that, the presence of tyro...
Improving Printability of Wool Fabric with Anoinic Dyes Using Redox Systems
Redox systems based on ammonium persulphate as oxidant along with ethylene glycol, urea, thiourea, glucose or formaldehyde as reluctant were incorporated in the printing formulations of wool to improve its printability with anionic dyes, i....
Starch–g-polyvinyl acetate copolymer Part 2: Utilization of starch-g-polyvinyl acetate copolymer in textile printing
In this study the starch-g-polyvinyl acetate copolymer with different acetyl contents were used as thickening agents for pigment and reactive printing. Pigment printing was applied on wool, cotton, nylon, polyester and cotton/polyester blen...
Color Discharge Printing Without The Use Of An Illuminating Dye
This abstract describes research conducted in fulfillment of a Degree of Masters of Science in Textile Management and Technology at the College of Textiles at NCSU. The research explored several methods for imparting colored patterns onto a...
Chracteristic Fading Curves for some vat and Vat-disperse dyes
Some vat and vat-disperse dyes were prepared and used for dyeing polyester, cotton and polyester-cotton blended fabric.The characteristic fading curves were examined.From the results obtained, it was found that dyes which were capable of fo...
