“…According to Nayak et al, the thermal resistance of aramid fabrics increases by increasing the number of laundering cycles. 19 In addition, the changes in the thermal conductivity of laminated nanofiber webs with repeated laundering 20 are similar to the results of the present study.…”

“…18 Nayak et al investigated the thermophysiological comfort properties of aramid fabrics upon repeated laundering and they found that the fabric thickness, areal density, thermal resistance and water vapour resistance values increased with the number of laundering cycles, whereas the air permeability decreased because of fabric shrinkage and swelling. 19 The effect of laundering on the thermal and water transfer properties of laminated nanofiber web for wear was also investigated. 20 Cotton and regenerated cellulosic fibres are generally preferred for next-to-skin fabrics, such as underwear and socks, for their high moisture regain and natural feeling during wear.…”

Air and water vapour permeability, thickness and thermal resistance of fabrics are some of the most important parameters to determine clothing comfort. However, these parameters tend to change after laundering in daily use. In this study, changes in the thermal comfort properties of cellulosic fabrics used in underwear and sock production, due to repeated laundering, were investigated. For this purpose, 100% cotton, viscose, Viloft, Modal, Promodal and Tencel fabrics, in single jersey construction, were selected and the thickness, air permeability, water vapour permeability and thermal resistance of the fabrics were measured initially and after 5, 10 and 15 repeated launderings. The obtained data were analysed by statistical techniques. According to the results, increasing the number of laundering cycles decreases air permeability and increases thickness and thermal resistance, in general. However, relative water vapour permeability decreases up to a number of laundering cycles and increases from this point on, upon further increasing the number of laundering cycles. The material type was found to be more influential than thickness on the thermal resistance values in this study. In conclusion, repeated laundering and material type significantly affect the comfort properties of fabrics.

“…The reduced air permeability may result in the lower water vapour resistance and hence cause discomfort to the wearer. However, as the fabrics are used in single layers the water vapour resistance, which is generally in the lower range for denim will be changing marginally [37]. From statistical analysis it was observed that there is a significant difference in fabric air permeability of the three denim fabrics having different Lycra content (F=3366.718, p ≤ 0.001).…”

The performance of a garment during its usage is very important for consumers. Performance as such is a very wide term and may range from satisfying the requirements during its use to the durability. Comfort is also considered by many consumers today as one of the performance requirements. For stretchable denim fabric, the fit related comfort lies in the ability of the material to be stretched when a load is applied according to body movements and retain to its original length. While designing the stretch denim, fabric weight and weave plays important role for comfort, performance and fashion. In this study, the effect of fabric parameters such as areal density, Lycra content and weave on characteristics of stretchable denim fabrics were investigated. Various properties such as thickness, tensile strength, flexural rigidity, stretch and recovery properties and air permeability of the fabrics were evaluated. The test results revealed that increasing the fabric weight increased fabric warp tensile strength, compressibility, stretch and recovery, whereas the flexural rigidity, weft tensile strength and air permeability were decreased. As Lycra contents in fabric increased, fabric thickness was increased which resulted in higher flexural rigidity of fabric. Fabric construction and weave also influenced the fabric flexural rigidity and air permeability related to performance and comfort of stretchable denim fabric.

<p>Some sports involve frequent collisions between the players, and between a player and the playing surface, leading to injuries such as muscular strains, dislocations, sprains, lacerations, fractures and soft tissue injuries. In several instances, these injuries are so severe that they may cause bone fracture or dislocation of joints. In recent years, researchers are focusing on reducing these injuries by using protective gears and protective clothing to cover the torso, head, hands and legs. For rugby uniforms, shoulder pads are integrated to reduce the incidence of shoulder injury during the making or receiving of front-on tackles. Although some shoulder pads such as closed cell foams are commercially available, they are often discarded by the players due to their stiffness and discomfort. Hence, in this research an attempt was made to explore the potential of using flexible textile structures to replace the currently used commercial foam. Three flexible textile structures (A, B and C) were designed in three dimensional (3D) structure using Shima Seiki flatbed machine. Each fabric consisted of 3 layers, 2 external (face and back) and one internal layer. Fabric A consisted of mercerized cotton (space dyed) and Elastane external layers, whereas ballistic nylon internal layer. Fabrics B and C were prepared using Dyneema (untwisted) and Elastane external layers and Dyneema (untwisted) internal layer, but with different structures. These textile structures were analysed for their collision protection using the technique of ‘drop test’. The test was based on principle of energy absorption by the textile structure due to the impact of a hard surface with them. It was assumed that the higher is the energy absorbed by the textile structure, the smaller will be the impact to the wearer. It was found that the 3D structures can provide equivalent amount of impact protection as the commercial foam (Sample D). The flexible structures recover easily with the body movement, and provide a high level of comfort. The methods of drop-test including the results are discussed in this paper. The findings of this study suggested that an equivalent level of protection can be achieved with the use of 3D textile structures and higher amount of comfort for the rugby players. Hence, the 3D textile structures can be used as an alternative material to replace the commercial closed foam currently in use in the shoulder pad to achieve similar protection and improved thermal comfort.</p>
