Abstract Background Compression socks are highly recommended textile garments for the exertion of compression pressure (kPa) at the ankle. They work on the principle of the highest pressure at the ankle gradually decreasing from the ankle to the calf. Aim The aim of the current research is to analyze all of the compression sock samples (Class I, Class II, and Class III) simultaneously at various number of times of washing them. Method All of the sock samples were washed in a standard washing machine with standard methods (ISO 6330). For the measurement of the compression pressure, a Salzmann MST MKIV pressure measuring device was used according to the RAL-GZ 387/1 method. Results Results included the effect of multiple wearing and washing cycles (up to 20) on compression pressure, the effect of temperature (up to 100°C) on compression pressure (kPa); multiple wearing and washing cycles on the percentage of shrinkage and the effect of marking methodology on compression pressure (Kpa) were observed and are discussed in this article. The results suggest that washing is the most important factor to consider while compression socks are used for compression therapy because they directly influence the efficacy of streamline blood flow across the legs.

Abstract The process of retting bast fiber plants for the production of long fiber has presented major challenges. Water retting, dew retting, chemical extraction, and micro-organism (fungi, enzymes) techniques were applied to the extraction of natural fibers. The two nettle samples were extracted with water retting for 14 days and dew retting for 4 weeks. This research investigated the effects on the traditional retting process of nettle fiber by fungi and bacteria formation in lignocellulosic. The latter biological extraction methods successfully degraded the lignin and pectin materials of the fiber and increases the cellulose content. These extraction methods produced high quality fiber and tensile strength at a low cost. This study determined the chemical, physical, and mechanical characteristics such as fiber cellulose, non-cellulosic content, tensile strength, tenacity, and elongation break to see how treatments affected them. The treated fiber surface morphology was characterized using scanning electron microscopy. To evaluate functional group alterations, Fourier-transform infrared spectroscopy was used on the fiber specimen.

Abstract The rapid development of the textile industry has led to the demand for more advanced textile equipment because the current covering yarn machines are large and expensive and have a large physical footprint. Also, the current technology is unsuitable for most laboratory research and small factory proofing. In this paper, the principle of forming covered yarn is analyzed and simplified in three systems: the unwinding system, the covering system, and the winding system. A small sample of low volume and better flexibility is developed, the production process and primary structure of the covered yarn prototype are introduced, and the covering effect of the small prototype is debugged and analyzed.

Graphical Abstract Abstract The effect of sodium lignosulfonate (LS) treatment on nylon fabric for enhancing its ultraviolet protection ability has been studied. Various concentrations of LS were applied on nylon fabric using the exhaust method and the treatment was optimized using Box–Behnken response surface design. The ultraviolet protection factor (UPF) is achieved, as high as 62.13 with one such LS-treated nylon fabric. The LS-treated nylon fabrics were characterized using FTIR, FESEM, Energy dispersive X-ray (EDX), and Thermo-gravimetric analysis (TGA) instruments. The UPF and color-strength (K/S) values are significantly increased with an increase in the concentration of LS without any loss of tensile properties and thermal stability. The LS treatment has excellent wash fastness.

Abstract The properties of viscoseTiO2 and viscoseTiO2germanium dioxide (GeO2) are investigated and compared. The elemental mapping analysis using a field emission scanning electron microscope (FESEM) shows the excellent distribution of nanomaterials, while the energy dispersive X-ray (EDX) confirms its existence. The 500 s cycle of rubbing test indicates that the abrasion resistance of treated samples improves significantly. In addition, the doping of nano GeO2 enhances the strength of the treated samples. Furthermore, the thermal behavior of the treated samples, characterized by differential scanning calorimeter (DSC), results in a higher crystallization temperature and doping GeO2 increases the thermal properties of viscose in comparison with nano TiO2. The study of ultraviolet blocking indicates that doping GeO2 can improve the transmission of ultraviolet even from TiO2.

Abstract In order to investigate the effect of washing water pH on textile damage for delicate garments, the study was conducted such that a customer survey was first applied to randomly selected users to analyze domestic washing machine using habits of Turkish consumers. Based on the findings of the survey, the experimental study was designed in two successive phases to investigate the dimensional and mechanical behavior of certain types of delicate textiles against varying washing conditions by taking in particular, water properties, namely pH, hardness, and temperature into account, and accordingly to determine the optimized washing conditions for such textiles. Firstly, tergotometer was employed as a washing machine simulator. Within the light of the results obtained, the experimental work of the second phase of the study was conducted, which involved a domestic washing machine as a real-life scenario. All of the results, including the correlation between the data sets obtained from the tergotometer and domestic washing machine trials, were statistically analyzed using Minitab 17. The study produced some important findings regarding the effect of washing water pH on delicate textiles, in addition to an algorithm for improving the present washing program, minimizing textile damage for mainly wool and silk garments.

Abstract The glass fiber reinforced resin matrix composite I-beams were designed and formed via a type of novel bending pultrusion processing technique, and the three-point bending tests were carried out to analyze the mechanical bending performances. The obtained results show that the main failure mode of the composite I-beam under the bending load is the upper structure (top flange) cracks along the length direction of the fibers, and the cracks simultaneously propagate downwards in the vertical direction. The bifurcated cracks can be found at the junction area between the top flange and web. In addition, the main bending failure mechanism of the composite I-beam includes the matrix cracking, propagation of cracks, and final fracture failure. In particular, noting that when the crack reaches the I-shaped neck position, the lateral bifurcation occurs, and the resulting secondary cracks further extend in two directions, which leads to the serious damage between the top flange and web, and the ultimate fracture failure occurs.

Abstract Recently, there is an increasing interest in design of circular weft jacquard because of the pursuit of fashion and comfort. Aiming at the complexity of the computer-aided design method of the existing circular weft-knitted jacquard fabrics, which is not conducive to the rapid design and intelligible for designers, a design method was proposed to transform pattern notation into knitting diagram efficiently, which was based on knitting rules and its creation as a set of jacquard modules. Knitting characteristics of jacquard fabrics were studied as a precondition. On this basis, the design procedures of jacquard modules were analyzed and illustrated by taking tricolor bird's eye backing jacquard as an example. Jacquard modules with various jacquard effects were designed and stored in a jacquard module database. To mathematically describe pattern notation, knitting diagram, and jacquard module, two-dimensional matrixes were established by the method of mathematical modeling, and a corresponding algorithm for the transformation of the pattern to knitting information according to the knitting rules of jacquard modules, which can be applied to ordinary jacquard fabrics was summarized. The project of tricolor circular weft-knitted jacquard with bird's eye in the reverse and four-color air-layer jacquard were taken for instance to verify the models and algorithm. The results obtained show that the approach can efficiently and conveniently realize the designation and machine-knitting of weft-knitted jacquard fabric, which provide a theoretical basis and notation of modeling for the computer-aided design of circular weft-knitted jacquard fabrics.

Abstract This paper presents a novel magnetic twisting device with a coaxial double rotor based on non-contact transmission characteristics of magnetic drive technology. When the twisting device rotates one cycle, the yarn can get triple twists. This means the new device can twist three times more than what the traditional single twist does. The structure of the magnetic twisting device is designed according to the twisting principle. The influence of main structural parameters on the magnetic torque is analyzed. To optimize the maximum transmission torque and the minimum magnet volume, the multi-objective optimization design model for the twisting device is established. Main parameters such as the relative angle of active disc assembly and passive disc assembly, the thickness of magnet, and the average radius of the magnet distribution are optimized by NSGA-II algorithm. Optimization results show that the proposed structural optimization design of a twisting device based on the magnetic drive has excellent performance and is effective for industrial application.
