Comfort properties of knitted fabrics used for intimate wear is an important matter to be dealt with. Hence, the comfort issue of the knitted fabrics made of micro-rayon and lyocell fibers were examined in the current study after they were separately treated with the antibacterial and wicking finishes. Moreover, the effect of spandex was investigated. The fabric samples were analyzed in terms of vertical wicking capacity, transfer wicking, water vapor permeability and drying rate. According to the results, spandex incorporation and process history were found to be influential on the vertical wicking capacity of the fabric samples whereas, spandex incorporation was found as the main affecting parameter for the transfer wicking. Moreover, fiber type and spandex incorporation were both found to have significant effects on the water vapor permeability of the fabric samples. The best fabric option from its alternatives for intimate wear was chosen by the hybrid AHP-TOPSIS approach. [ABSTRACT FROM AUTHOR]

The textile industry has recently been developing innovative products that integrate functional properties within commodity textiles. In particular, research has focussed on the concept of biofunctional textiles, i.e., textile materials possessing beneficial properties for human health. Biofunctional textiles are synthesised by functionalization of fabric surfaces with biopolymers. As an example, the chitosan biopolymer is promising for textile functionalization due to chitosan availability, low cost, safety and unique properties. Yet several challenges have to be overcome. Firstly, the morphology of chitosan must be optimized prior chitosan application to the textile surface. Secondly, the last treatment must be carefully designed in order to achieve an effective and durable functionalization. Lastly, the overall production process must comply with environmental rules concerning pollution emission and utilization of harmful substances. This review describes microencapsulation as a strategy to overcome limitations and to confer better properties to the textile material. The properties of chitosan and the concept of microencapsulation are presented. Then we present the main techniques of chitosan encapsulation. Furthermore, we detail the textile finishing processes and the textile products. Last, the perspectives are discussed in the context of green chemistry and compliance with an environmentally friendly approach. [ABSTRACT FROM AUTHOR]

The principal purpose of this work is to develop a new approach to model and predict the fabric shrinkage in denim garments after finishing treatments. This study was carried out on denim blue jeans fabrics of different structures which are transformed into pants. The shrinkage 056 measured at different parts of the pant (waist, hem and knees). A factorial design analysis with 960 experiments conducted under industrial conditions and repeated three times was applied to study the garment shrinkage behaviour. A standard method was modified to characterize the potential shrinkage of the denim garment fabrics and to model their intrinsic shrinkage parameters. Relevant models calculating the fabric shrinkage of the denim garments in the different treated zones of pants according to the finishing treatments are identified and validated in three industrial orders. The obtained results, statistically and industrially validated, show very well the accuracy of the established shrinkage prediction models and their reliability to be applied in industrial scale.

Abstract: Direct Metal Laser Sintering (DMLS) is a rapid manufacturing technology that is starting to be used for the manufacturing of functional components. Therefore, properties of DMLS manufactured parts must be carefully analyzed to determine if they satisfy technical requirements under fatigue conditions. In this work, the structural integrity of Maraging Steel, Inconel 718 and CoCr alloy DMLS parts subjected to different thermal and finishing (shot peening and surface polishing) treatments has been characterized in order to determine the optimum stabilization treatment with regard to structural integrity. For this characterization, surface residual stresses, microstructure, porosity and hardness of the parts have been studied. In general, DMLS process origins detrimental surface tensile stresses in Inconel 718 and CoCr alloy components whereas in Maraging Steel parts DMLS results in light surface compressive stresses that improve in general with the application of subsequent thermal and mechanical treatments. Moreover, surface polishing homogenizes the final stresses resulting, besides, in very compressive surface residual stresses. [Copyright &y& Elsevier]

The principal purpose of this work is to study the dimensional stability of cloth upon seaming, particularly after finishing treatments. This study is carried out on denim blue jean fabrics with different structures which are transformed into pants. Various types of assembling are used, such as safety stitch, felled seam and lockstitch. The sewing operation is carried out with the same parameters: the stitch type, stitch density per centimeter, and sewing thread count and composition. The garment shrinkage is influenced by several parameters, such as the type of assembling and the industrial finishing treatment. The results show that the type of industrial seaming, resin treatment and special treatment as well as their succession has a significant effect on garment shrinkage. There is more shrinkage in the garment assembled with a flat-felled seam than that with a safety stitch. The difference can reach 57.8% if the garment is treated with mixed methods, such as washing and chemical special treatment. Moreover, the shrinkage measured on the waist or hem is less than that measured on the legs. Finally, the shrinkage due to the type of assembling in the warp direction is more than that in the weft direction. [ABSTRACT FROM AUTHOR]
