A Study on the Effect of Plasma Modification on the Comfort Properties of Polyester/Cotton Blend Fabric
In this dissertation, the effect of cold plasma treatment on the comfort properties of P/C blend fabric has been studied in a low pressure plasma reactor. The plasma treatment was conducted on the samples of 65% polyester and 35% cotton blend fabric using argon, oxygen and air, separately, as well as mixtures of O2/HMDSO, N2/HMDSO, H2O/HMDSO and HMDSO monomer alone as working gases. Special attention was given to oxygen plasma due to its wide application for various textile/polymer materials. Due to this reason, the Taguchi method was used to design, analyze and optimize the oxygen plasma process. Other plasma parameters including working pressure, discharge power, duration of treatment and flow rate were also considered. The various comfort properties of plasma treated and untreated P/C blend fabric have been studied. In particular, thermal comfort such as, water vapor, air permeability, thermal resistance and wickability as well as tactile comfort including hand-feel and electro-physical properties were investigated. As the results showed that the oxygen plasma treatment had a positive effect on the thermal comfort and resistivity properties of P/C the blend fabric.
Surface Modification of Textiles
The surface of textiles offers an important platform for functional modifications in order to meet special requirements for a variety of applications. The surface modification of textiles may be achieved by various techniques ranging from traditional solution treatment to biological approaches. This book reviews fundamental issues relating to textile surfaces and their characterisation and explores the exciting opportunities for surface modification of a range of different textiles.Introductory chapters review some important surface modification techniques employed for improved functional behaviour of textiles and the various surface characterisation methods available. Further chapters exami...
Innovative and Emerging Technologies for Textile Dyeing and Finishing
With the public enhanced awareness towards eco-preservation, eco-safety and health concerns, environmentally benign, nontoxic and sustainable bioresource materials produced mainly from non-food crops have revolutionized all industrial sectors particularly textile industry. In recent years, textile industries in developed countries are getting increasing interest in global interest due to the varied and changing world market conditions in terms of price, durability and fiber mixtures as well as design, colors, weight, ease of handling and product safety. The increasing environmental and health concerns owing to the use of large quantities of water and hazardous chemicals in conventional texti...
Teff: nutrient composition and health benefits
Teff (Eragrostis tef), has been cultivated and used for human consumption in Ethiopia for centuries. However, teffs global use for human consumption has been restrained partly due to limited knowledge about its nutrient composition and the processing challenges faced in making teff-based food products. Over the past decade, the recognition that teff is gluten-free has raised global interest. Consequently, literature on the nutritional composition, processing quality, and health benefits of teff has grown considerably. The existing literature suggests that teff is composed of complex carbohydrates with slowly digestible starch. Teff has a similar protein content to other more common cereals like wheat, but is relatively richer than other cereals in the essential amino acid lysine. Teff is also a good source of essential fatty acids, fiber, minerals (especially calcium and iron), and phytochemicals such as polyphenols and phytates.
Landscapes and Landforms of Ethiopia
This book provides a succinct but comprehensive presentation of key geomorphological locations and topics including information about geomorphological heritage and maps to visit the most important sites. Apart from often being remarkably scenic, landscapes reveal stories that often can be traced back in time tens of million years and include unique events. This is particularly true for Ethiopia where spectacular examples of different landforms are present. Its geomorphology varies from highlands, marked by high volcanoes and incised by deep river gorges, to the rift valley lakes endorheic systems and the below sea level lowlands with characteristic landscapes which are unique in the world. Landscapes and Landforms of Ethiopia highlights all these topics including essential information about geology and tectonic framework, past and present climate, hydrology, geographical regions and long-term geomorphological history. It is a highly informative book, providing insight for readers with an interest in geography and geomorphology.
