Title: Potentiality of cotton nonwoven fabrics Authors: Rakshit, Arup K; Ghosh, S K; Talukdar, M K Abstract: Cotton, the age old fibre in the field of textiles, still holds its potentiality. Various developments and modifications, both physical and chemical, have been made to the fibre with a parallel importance given to product development and identifying the diversified fields of application. The world statistics indicate that cotton fibre accounts for more than 46% of all textile fibres used today. The properties that make it particularly suitable for nonwovens are its absorbency, vapour permeability, handle, wicking, crimp retention, biodegradability, low electrostatic build up, good cover and opacity. Cotton can also be easily sterilized to find a place in the field of medical application and personal care products. Above all, it is comparatively cheap and readily available in India and several other countries. This paper relates the importance of cotton fibre for specific end use products made from nonwovens, highlighting the potentiality of this fibre in various fields of application. Page(s): 224-227

Title: Critical factors affecting the properties of thermal-bonded nonwovens with special reference to cellulosic fibres Authors: Desai, A N; Balasubramanian, N Abstract: The ability to engineer the feel and functional requirements in light- and medium-weight goods without contributing to environmental pollution makes the thennal bonding process an interesting technology of nonwoven production. The manufacturing conditions, processing parameters, and the characteristics of binder fibres have a large bearing on the properties of nonwoven products. Higher calender roller pressure makes the nonwoven product more compact and stiff and increases the strength up to a point. Higher binder fibre concentration also makes the nonwoven more compact and stiff but decreases elongation and crease recovery angle. Studies on the mechanism of bonding reveal that the polymer flow under the influence of temperature and pressure is a complex phenomenon and is also influenced by the process speed. Quench rate has a significant bearing on the properties of thermal-bonded nonwovens. Hence, the critical processing parameters such as binder fibre content, temperature, pressure and speed are to be optimized for the cellulosic blends to achieve the fabric requirements for applications such as interlinings, medical and wipes. Cellulosic thermal-bonded nonwovens with their superior absorption characteristics are ideal for next-to-skin applications. Page(s): 209-215

Title: Effects of selected fiber properties and needlepunch density on thermally-treated nonwoven fabrics Authors: Ghosh, Subhas; Dever, Mary; Thomas, Howard; Tewksbury, Charles Abstract: The effects of polypropylene fiber length, polyethylene binder fiber concentration and needlepunch density on the physical properties and appearance of thermally-treated needlepunched nonwoven fabrics that are normally used for side panels, truck lines, rear shelf liner and seat backing in automobiles have been studied. It is observed that tensile and shrinkage properties are significantly affected by fiber length, polyethylene content and needling density. The presence of polyethylene binder fibers causes significant improvement in fabric appearance after abrasion. Page(s): 203-208
