Abstract: This work presents a systematic review to provide an overview of the possibilities for coupling, fabrication or embedding of electronics into textiles whilst assuring the capability of these products to meet the requirements of a sports modality. The development of smart wearables systems for sports based on textiles attracts more and more users – motivated by design, by technology, as well as by the expectation of increased performance. A bibliographic search was carried out using the following databases: Scopus, Web of Science, IEEE Xplore and Science Direct. This study includes 32 articles and discusses these in a new taxonomy with three dimensions: measured variable, types of feedback and applications. Of the 23 technologies surveyed, this review showed that these wearable systems are mainly used for vital signs monitoring and to provide feedback on the electrical activity of the heart, with sensors mostly placed in the chest. Usually, the technologies are externally attachable rather than embedded in the textile. We observed that the implementation of design as the process of development of e-textile products is still only scarcely present in these studies.

Abstract: The article deals with the effect of the wear coefficient of high-manganese steel on service durability indicators of castings, which are produced from this steel and operate under conditions of intensive wear. The article introduces the results of computer simulation of crystallization and cooling processes in high-manganese steel castings in the mould. The effect of the casting cooling rate in the mould on the cast steel primary structure, as well as on the value of its wear coefficient has been studied. The effect of primary crystallization on austenite grain size and its microhardness has been examined and the crystallization rate resulting in the formation of a uniform structure of the alloy has been determined. The effect of cooling rate of high-manganese steel in the temperature range of the precipitation of proeutectoid constituents on their quantitative characteristics and morphology, as well as the hardness of the alloy as a whole has been examined.

Abstract: Dralon superfine profiled acrylic interwoven with traditional spun silk .There are 9 kinds of interlaced fabric. We discussed that in same condition of finishing and fabric weave (3/1right twill),different picking shuttle between superfine profiled acrylic and spun silk have a impact on fabric performance of moisture absorption, air permeability, drape, crease recovery and warmth retention. The results showed that: fabric has better wearability when silk and acrylic picking proportion is 1:5(That is the content of acrylic is 61.16%).

Abstract: PTT material is suitable for shaping clothing because of its excellent shaping and crease recovery performance, but if as underwear, the wearability of PTT material is being questioned. Based on the L₉(3⁴) orthogonal array design, two kinds of samples were kitted utilizing nylon core-spun yarn as ground yarn PTT/nylon filament and Polyester/nylon filament as face yarn respectively, mixed proportion and structure were controlled in the sample design. Test 6 basic wearabilities of samples, the wearabilities of samples were investigated by fuzzy mathematical analysis. The results of this research can be a good reference of shape wear fabric selection.

Abstract: In this paper,the soybean protein / poly (ethylene terephthalate)PET composite fabric was obtained and its wearability was mainly studied. It is found that the moisture regain, water absorption, air permeability and moisture permeability of soybean protein PET composite fabric were improved greatly. In addition, the whiteness and elastic wrinkle recovery angle kept well, and the stiffness increased incredibly. Therefore, soybean protein being grafted on PET fabric surface not only improved the biocompatibility, but also the wearability.

Abstract: The paper explores the effect of a modifier based on ultrafine powders of refractory metal oxides on the change of structural state, phase composition and mechanical properties of cast iron of ИЧХ28Н2 (Russian grade). It was shown that the modifier added to the melt does not change the phase composition of ferrite-austenitic matrix and carbides and is not carbide-forming. Material microstructure changes only due to the presence of a large amount of crystallization nuclei during the casting cooling. It was established that the modification increases the ultimate stress limit by 53%, plasticity by 10.7%, corrosion resistance by 15%, and leads to the reduction of friction factor and linear wear due to the decreasing of structural elements: carbide phase and austenitic-carbidic eutectic.

Abstract: To research the relationship between wearability of traditional Mongolian clothing fabrics and geographical location and climate of mongolian regions, nine mongolian clothing fabrics of Barag Banner, Ujimqin and Chahar Right Back Banner in China were selected. According to geographical location and climate of three regions, their structure parameters and comfort performances were analysed. The most primary characteristics of clothing fabrics in mongolian region were concluded in this research, which must be valuable to the environment adaptability research of human to Mongolian Plateau.

Abstract: The content of magnetic fiber is the determinate element of both the surface magnetic field intensity and the economic cost of the magnetic fabric. It probably has certain influence on fabric wearability. In this study, experimental method has been adopted to investigate the wearability of knitted magnetic fabric which is woven of magnetic fiber and non-magnetic fiber in different proportions. The mechanical property, pilling resistance, moisture permeability and other properties of magnetic fiber have been tested. The results of study shows that as magnetic fiber content in the magnetic fabric increases, the breaking strength, bursting strength and pilling resistance of the fabric decrease and the moisture permeability variation. But the bending property, drapability and dimension stability of the fabric nearly have no evident relation with the content of magnetic fiber. This study can provide references for the further research of the magnetic health-care garment and will make the magnetic fabric better uses on garment.

Abstract: This paper selected 10 kinds of fabrics of thermal underwear, which are the representatives on the market; carried out tests on the fabric properties (thickness, density, the gram per square meter, etc.) and the fabric wearability (permeability, water vapor permeability, wicking height, insulation and antistatic properties, etc.); analyzed these data by using SPSS, finding out the factors which effect the warmth, moisture permeability, air permeability, etc, as well as the relationship between these factors. This article evaluated fabric wearability comprehensively by using concentrated reflection method and function value evaluation method to select the proper fabrics of thermal underwear under different conditions. The results of this research can be a good reference of thermal underwear fabric selection for enterprises.

Abstract: For precise geometrical design and wear-resisting design of the roof diamond tool for ruling echelle grating of large area, computer aided reverse design was used to solve the problems. Firstly, based on the mechanical parameters of grating， Al film got from the nanoindentation test and nanoindenting simulated analysis. The optimized geometrical parameters of the roof diamond tool are got with an orthogonal analysis in a dynamical finite element model of simulating mechanical ruling. Then an equivalent resistance design method is put forward to improve the wearable ability of the roof diamond cutter with wear simulated analysis. Finally, a roof diamond tool of trial-lapping is presented for grating ruling investigation to verify the design effect.
