- ItemImpact of Different Weft Materials and Washing Treatments on Moisture Management Characteristics of Denim(Inda, 2012) Mangat, Muhammad Mushtaq; Hussain, Tanveer; Bajzík, VladimírThe aim of this study was to investigate the effects of different types of weft yarn materials and washing treatments on the moisture management properties of denim fabrics. Fabrics were developed with five different types of weft yarns made of cotton, polyester, spun polypropylene, air-textured polypropylene and stuffer-box crimped polypropylene. In all cases 100% cotton yarn was used as warp. Samples from each fabric were subjected to 10 diverse types of washing/finishing treatments and the treated samples were tested for dissimilar moisture management indices on an SDL Atlas moisture management tester. The statistical analyses of the test data show that the effect of different types of weft yarns and washing treatments is significant. Based on the results of this study, denim fabrics can be developed with enhanced moisture management properties.
- ItemThermal resistance models of selected fabrics in wet state and their experimental verification(Sage Publications Ltd, 2015) Mangat, Muhammad Mushtaq; Hes, Luboš; Bajzík, VladimírThis study investigated the structural model of textile fabrics affected by moisture. The model has been verified through five fleece fabrics made up of various textile materials and subjected to several mechanical surface treatment levels. Thermal resistance is one of the key parameters of thermal comfort along with water vapor permeability. In recent times, a keen interest has been focused on the mathematical modelling of this parameter and its experimental verification. However, most of these efforts are made to describe dryness in thermal resistance of fabrics, ignoring the wet condition found in protective and outdoor clothing. To determine the thermal resistance value of the studied fabrics, the ALAMBETA semiautomatic nondestructive thermal tester was used. The findings show that the proposed model displays substantial harmony with the experimental data.
- ItemThermal Resistance of Denim Fabric under Dynamic Moist Conditions and its Investigational Confirmation(Inst Chemical Fibres, 2014) Mangat, Muhammad Mushtaq; Hes, LubošThe goal of this study was to examine whether there is a correlation between the moisture content in fabric and the thermal resistance thereof Denim fabric made of five different compositions of fibre content was used for testing thermal resistance under dynamic moist conditions. An ALAMBETA semi-automatic non-destructive thermal tester was used to check the thermal resistance. A mathematical equation was developed for prediction of the thermal resistance of denim fabric submersed in water at different moisture levels. This model is based on the relationship between the density ratio of the fibre and fabric, the thickness of the fabric and the amount of moisture therein. A number of simulations were tried and finally one arrangement found that has significant agreement with actual values. This model can be used for other types of fabric because there is no role of the geometry of fabric in it. The model proposed exhibits a substantial link with the experimental data.
