The application of 3D printing technology has been relatively slow in the fashion industry. Both in the fashion industry and in 3D printing, the material used plays a very important role. In this direction, thermoplastic polyurethane (TPU) is one material that has started to grab the attention of researchers, producers, and customers. While many have studied 3D printing technology using thermoplastic polyurethane material in the fashion industry from different perspectives, fewer researchers have addressed the actual adoption of thermoplastic polyurethane based 3D printing in the fashion industry. Thus, the present research has been focused to propose an adoption model for thermoplastic polyurethane based 3D-printed fashion clothes. Factor analysis was conducted to find and analyse the most relevant factors. Further exploratory factor analysis was conducted to test the proposed model. The study proposed a model for adoption based on four factors: motivation to buy, customer attitude, and the challenges and benefits associated with the adoption of thermoplastic polyurethane based 3-D printed fashion clothes.

Currently, the knotting of chemical fiber filament packages in factories primarily comprises manual operations. It also has a high labor intensity and is subject to artificial subjective factors, due to which it is difficult to guarantee the quality of the finished fiber products. Furthermore, it also significantly restricts the intelligent construction of chemical fiber production. This work employs partially oriented yarn (POY) and full draw yarn (FDY) to develop an automatic knotting device. The catenary theory was used to confirm the state of the yarn and to determine the relevant parameters of the tension mechanism. The results showed that the developed automatic knotting device satisfactorily meets the conditions required for manual knotting. The curve equation that was calculated using the catenary conformations of the yarn state verified that the actual yarn state was consistent with the theory. Moreover, the work provides a theoretical foundation for subsequent mechanism optimizations.

This paper aims to discuss the artistic characteristics of traditional cheongsam and the transformation that has taken place in cheongsam textile design in the Republic of China. By analysing a collection consisting of 259 traditional cheongsam material samples in various museums such as the China Silk Archives in Suzhou, we explored the transformation of cheongsam textile design during the Republic of China from the perspective of Eastern and Western art cultural exchanges and explored the spread of Western artistic thought in China. Our research shows that, firstly, with the development of industrialization, the traditional cheongsam textile business absorbed new design concepts; secondly, in terms of material selection and pattern style, it widened the range of fabrics used and broke the monotony of traditional Chinese patterns. Moreover, it reduced connotations of social class implied by traditional textile design. Finally, these textile designs reflect the progress that has been made in the development of this artistic trend and the cultural fusion of Eastern and Western arts during the Republic of China.

The fast-fashion business model is marred by high resource consumption and enormous emission of greenhouse gases. It is based on inaccurate forecasts, resulting in excess supply than demand. Globally, 85% of two-week-old garments end up as unfashionable or worn-out items that must be discarded as waste, disposed of for recycling, or donated to charities. With this colossal increase in textile waste, resource efficiency is one of the biggest challenges facing the fashion industry, which now calls for a swift implementation of a new sustainable business and consumption model to extend product life cycles. This demand for sustainable consumption encourages consumers to reuse, recycle and resell. The resell campaign known as second-hand clothing is a growing market worldwide. Current global forecasts predict a 185% increase over the next ten years, compared to FF, which will expand by just 20%. Africa is a top destination, with more than 80% of its population wearing SHCs. We contribute to this literature by assessing the significance of SHC trade in Liberia. We extend this assessment by developing a hybrid MCDM tool incorporating AHP, fuzzy logic, Ensemble, and TOPSIS to build a SWOT framework to identify criteria and sub-criteria for prioritizing SHC retailing in Liberia and Africa. Data for this study were gathered from a survey involving 100 SHC retailers from the Red-Light, Waterside, Duala, and Omega markets in Monrovia, Liberia. We identified several important factors in implementing sustainable SHC and recommended strategic directions towards their successful implementation.

This study analyzes how the beta index, which is closely related to alertness, caution, concentration, anxiety, and tension in brain activity, varies before and after practicing yoga. Electroencephalogram (EEG) and subjective evaluations were conducted on healthy female yoga trainers with over three years of experience; participants wore yoga clothes with differing characteristics in a hot environment. Repeated ANOVA measurements were conducted on the data by deriving the difference between the corresponding sample t-test pre- and post-yoga. After yoga, concentration increased, while alertness, anxiety, and excitement decreased depending on the yoga clothes. The clothing combination that offered higher pressure and greater absorption, and enhanced concentration while lowering excitation and anxiety increased beta waves the most. The design characteristics of yoga clothes influence beta power for concentration and arousal after yoga practice. Through EEG measurements, it was possible to explore the mental states resulting from wearing clothes suitable for yoga.

Reports attribute many physical, psychological and mental benefits to yoga sports. However, when it comes to actual research, yoga clothing has not attracted the same level of attention. The aim of this study, which involved a questionnaire survey, clothing development and clothing performance evaluation, is to propose an ergonomic design process for the design of yoga functional clothing. Results showed that textile material was rated as the most important factor for yoga clothing. The shoulder and the waist-belly regions were considered as the most important areas for yoga clothing. The newly designed clothing prototype was observed to subject significantly lower pressure to the waist under the forward bending pose (p&lt;0.05), but with significantly higher pressure on the buttocks at the posture of the deep knee bending pose (p&lt;0.05). It also resulted in a lower change rate of clothing vertical displacement, especially at the shoulder and waist regions. The newly designed prototype was rated with a significantly lower tightening sensation and pulling sensation during the deep knee bending posture (p&lt;0.05). Results indicate that proper design of yoga clothing structure and selection of fabric material could reduce clothing deformation, pressure on the skin and improve subjective wearing sensations.

Worksites at height require the protection of workers during both movement and task performance. The rope access technique involves the simultaneous use of working and backup textile rope systems. Currently, kernmantle ropes are most often used in conjunction with mechanisms that move along them and lock at the right moment. However, this mode of operation has a destructive effect on the rope. Ropes must therefore meet a number of specific requirements, one of the most important of which is sheath slippage. The paper presents a method for testing this parameter based on the requirements of EN standards, including the design and implementation of a test stand and a method for the verification of its operation. Test results for 11 types of ropes are presented and discussed. The paper also provides some guidelines for conducting tests.

A theoretical regularity of the general behaviour of raw cotton as a porous medium in the technological processes of its mechanical processing has been substantiated for the first time. The speed of sound in a porous cotton medium has now been determined. The effect of additional force stresses inside the cotton medium caused by the filtration of the air component from cotton raw materials during the introduction of the working body, has been disclosed. A generalized equation that describes the force stress in a cotton medium when exposed to a variety of shapes of working bodies of cotton machines has been worked out. A method for calculating the damage to seeds and cotton fibers caused by their interactions with the working bodies of processing machines has been proposed.
The resultant theory that describes the stress state of cotton raw materials during processing allows us to use it practically to solve all important issues pertaining to the damage of fiber and cotton seeds that occur by using technological solutions in primary processing of cotton operations.

The aim of this study was to clarify how human movement speed and pants elasticity affect the athletic performance of knee joint protection by testing pants with different elastic properties: CP1 (tight pants) and CP2&amp;CP3 (elastic compression pants), which reinforce the knee joint. In addition, CS (cotton sport pants) was developed as a control garment. Three subjects wore CP1, CP2, CP3 and CS while running on the treadmill at three kinds of human movement speed. A three-dimensional motion capture instrument was used to capture the three-dimensional trajectory of the marked points of lower limbs. As a result, the influence of the movement speed on the kinematic parameters (AKJ &amp; gait cycle) was more obvious than the fabric elasticity. If elastic pants are worn during running, the change of AKJ will be stable with the increase of speed. When non-elastic pants are worn, the effect is opposite. Not only that, elastic compression pants are efficient in reducing the motion amplitude of the knee joint during the suspension period as far as 41°, making it highly practical in terms of stability. That is, the elastic fabric can protect the joints when the lower limbs are in motion. Moreover, with the increase of speed and elasticity, the elastic pants can reduce the gait cycle by up to 22% compared with non-elastic pants alone. Through the kinematics mechanism of human joints, these findings may translate into an effect on protective performance and a reduction in sport injuries. Therefore, it is necessary to wear elastic pants, especially compression pants, when running at higher speed, as the average gait cycle gradually decreases. This research shows that the knee joint protection functions of elastic compression garments differ according to the level of elasticity and differential movement speed, providing theoretical support for designing and producing elastic compression pants. It also acts as a guide for the research of lower limb joint protection.
