Fiber Structure Development and Mechanical Properties in Continuous Drawing and Annealing of Poly (phenylene sulfide) Filament

Abstract The study by chemical methods of the constitution, derivatives, and properties of cellulose has yielded a voluminous literature and a wealth of useful information. Microscopic and x-ray investigations have produced much new and valuable knowledge of cellulose and its structure. But relatively little attention is given to the mechanical properties of cellulosic fibers, although such properties reflect fiber structure and frequently determine suitability to specific applications. An exhaustive review of the relevant literature on cotton has not been undertaken in this paper; rather, the object is to summarize the available data on constitution and properties and, wherever possible, to indicate their relations to the most probable fiber structure. In this way the material as a whole is integrated into a working concept of the cotton fiber.

Abstract Ingeo® PLA (polylactic acid) knitted fabric was scoured through an exhaust technique. The scouring was carried out with sodium carbonate in the presence of a detergent at various concentrations and temperatures. The scoured fabric was bleached with various oxidative bleaching agents. Bleaching was carried out with hydrogen peroxide, sodium chlorite and sodium hypochlorite. Hydrogen peroxide was applied by exhaust and cold pad batch (CPB) techniques. It was observed that during scouring PLA fabric was degraded at high alkali concentrations and processing temperatures. The scouring temperature above 60ºC proved to be deleterious due to the scouring solution penetrating into the polymer structure and damaged the fiber. Sodium chlorite and sodium hypochlorite caused little damage to the mechanical properties of PLA. Hydrogen peroxide when applied by the CPB technique did not reduce strength appreciably but when applied by the exhaust technique decreased the strength significantly. SEM analysis revealed that hydrogen peroxide caused holes and slit formation in the fiber structure.
