Effects of industrial ironing on mechanical and dimensional properties of cotton,wool and polyester fabrics

The influence of industrial ironing cycle on low-stress mechanical properties and on dimensional changes in three selected weave fabrics has been studied. The experimental results are statistically analyzed using ANOVA. It is observed that the compressional properties measured by FAST system are the most influenced by the process of ironing. Cotton and wool fabrics show much variation in mechanical and dimensional changes compared to polyester fabric

Effect of solvent extraction on Tunisian esparto wax composition

The increase of needs for renewable and vegetable based materials will help to drive the market growth of vegetable waxes. Because of their highly variable composition and physicochemical properties, plant waxes have found numerous applications in the: food, cosmetic, candle, coating, polish etc... The aim of this project is to determine the effect of solvent extraction (petroleum ether and ethanol) on Tunisian esparto wax composition. The GC-MS was applied in order to determine the waxes compositions. Then, physicochemical parameters of these two samples of waxes: acid value, saponification value, iodine value and melting point were measured in order to deduct their properties and possible fields of uses. Results showed that esparto wax composition depended on the solvent extraction and that major components of the two samples of waxes were: alkanes, esters of fatty acids and phenols. Furthermore, esparto waxes were characterized by an antioxidant and antibacterial activities but the potential of these activities depended on the solvent of wax extraction

Investigating Waterproofness and Breathability of a Coated Double-Sided Knitted Fabric

The demand for waterproof breathable fabrics is increasing globally and so are efforts to develop such garments. In this paper, the development of a waterproof breathable textile by coating a double face knitted fabric is described. The applied polymeric coating is a mixture of an acrylic paste and a fluorocarbon resin. The aim of this study was the investigation of the breathability and waterproofness of the coated samples. The coating was made of industrialized chemical products and did not require water use. The screen coating process wastewater was also reduced. Three parameters related to the coating process were analyzed and optimized. These parameters were the fluorocarbon resin quantity (%), acrylic paste quantity (g&middot;m&minus;2), and reticulation time (min). The analyzed responses were the air permeability, windproofness, water vapor permeability, and resistance to water penetration. The optimized values of air permeability and water vapor permeability were equal to 154.81 L&middot;m&minus;2&middot;s&minus;1 and 83.852%, respectively. These values were judged acceptable when compared with commercialized products. The windproofness and the resistance to water penetration were equal to 161.81 L&middot;m&minus;2&middot;s&minus;1 and 78.51 Schmerber, respectively. Thus, both responses still need to be improved in order to obtain waterproofness properties. Based on the obtained results, the coated fabric can be used as a laminate outer layer for producing waterproof breathable fabrics
