However, few soft robots can mimic their gaits and achieve the same speed of movement. Inspired by the motion gait of cheetahs, here the resonance of double spiral structure for amplified motion performance and environmental adaptability in a soft-bodied hopping micro-robot is exploited. The 0.058 g, 10 mm long tethered soft robot is capable of achieving a maximum motion speed of 42.8 body lengths per second (BL/s) and a maximum average turning speed of 482° s-1 . In addition, this robot can maintain high speed movement even after flipping. The soft robot's ability to move over complex terrain, climb hills, and carry heavy loads as well as temperature sensors is demonstrated.

However, the fabrication of Textile-based TENGs remains a great challenge due to complex fabrication processes, low production speed, high cost, poor electromechanical properties, and limited design capacities. Here, we reported a new route to develop Textile-based TENGs with a facile, low-cost, and scalable embroidery technique. 5-ply ultrathin enameled copper wires, low-cost commercial materials, were utilized as embroidery materials with dual functions of triboelectric layers and electrodes in the Textile-based TENGs. A single enameled copper wire with a diameter of 0.1 mm and a length of 30 cm can produce over 60 V of open-circuit voltage and 0.45 µA of short circuit current when in contact with polytetrafluoroethylene (PTFE) fabric at the frequency of 1.2 Hz and the peak value of contact force of 70 N. Moreover, the triboelectric performance of enameled copper wire after plasma treatment can be better than that without plasma treatment, such as the maximum instantaneous power density can reach 245 μW/m which is ~ 1.5 times as much as the untreated wire. These novel embroidery TENGs possess outstanding triboelectric performance and super design capacities. A 5×5 cm 2 embroidery sample can generate an open-circuit voltage of 300 V and a short circuit current of 8 μA under similar contact conditions. The wearable triboelectric embroidery can be employed in different parts of the wear. A self-powered, fully fabric-based numeric keypad was designed based on triboelectric embroidery to serve as a human-machine interface, showing good energy harvesting and signal collection capabilities. Therefore, this study opens a new generic design paradigm for textile-based TENGs that are applicable for next-generation smart wearable devices. • Ultrafine, flexible, durable, and washable triboelectric yarn and embroidery were made from commercially available enameled copper wires. • A single 30 cm-long 0.1 mm-diameter enameled copper wire produces over 60 V of open-circuit voltage and 0.45 µA of short circuit current when in contact with PTFE fabric at 1.2 Hz under the contact force of 29 Kpa. • Plasma treatment of triboelectric yarn substantially improves the instantaneous power density by 50%. • A self-powered, fully fabric-based numeric keypad is demonstrated.}, journal={NANO ENERGY}, publisher={Elsevier BV}, author={Chen, Yu and Chen, Erdong and Wang, Zihao and Ling, Yali and Fisher, Rosie and Li, Mengjiao and Hart, Jacob and Mu, Weilei and Gao, Wei and Tao, Xiaoming and et al.}, year={2022}, month={Dec} }

In this work, a modified ring spinning technique has been developed by feeding three-roving strands into a conventional ring frame for producing yarns with better performance. A strand delivery guide with different spacings (1–5 mm) was used for the production of three-strand yarns. The quantitative relationships between the spinning parameters and yarn properties have been systematically investigated. The properties of the modified yarns were evaluated, including yarn tensile properties, evenness, and hairiness, and the statistical relationships were obtained by least squares polynomial fitting. The experimental results indicate that the guide spacing and twist multiplier significantly influence the yarn properties.

The potential fiber ends in yarns also play a crucial role in the performance of yarns in the subsequent processes and the resultant fabric quality. In our previous studies, maximum hairiness and its theoretical model have been proposed, which indicate the maximum fiber ends of a staple yarn having the potential to protrude out of yarn bodies and become hairy. On this basis, the relative hairiness index (RHI) is developed in this study to evaluate the fiber end tucking and securities of yarns. This index is treated as a ratio of the measured hairiness of sample yarns and the maximum hairiness of ring yarns in the same twist level and yarn count. A lower RHI indicates more fiber ends being tucked into yarn bodies, and a slower increment of the RHI with the increasing winding times represents more stable securities of fiber ends in yarns. The experimental results demonstrate that the RHI can directly reveal the effectiveness of different spinning parameters and methods in tucking and securing fiber ends; also, the changes of the RHI with increasing winding times visually present the stableness of fiber ends in various yarns experiencing abrasion, as well as predict the possibility of the potential fiber ends being pulled out to form hairiness during successive processes. The proposed RHI, therefore, provides a significant reference for the spinning process design and yarn quality control.}, number={3-4}, journal={TEXTILE RESEARCH JOURNAL}, publisher={SAGE Publications}, author={Huang, Xinxin and Tao, Xiaoming and Yin, Rong and Liu, Shirui}, year={2021}, month={Aug} }

Since its invention, ring spinning has become the most widely used spinning technology due to the high yarn quality and applicability. However, the productivity is limited by its twisting and winding mechanism. Viable approaches to substantially improve the throughput of ring spinning are crucial. Therefore, this paper presents a systematic review of the literature on the state-of-the-art of disruptive technologies aiming at improving the throughput of ring spinning. Based on the governing equation of ring yarn productivity, two approaches of increasing spindle speed via reducing or eliminating ring-traveler friction and reducing yarn twist have been scrutinized. Increasing the spindle speed directly increases the centrifugal force and air drag of the yarn in the spinning balloon and exacerbates the traveler's wear. By reducing or eliminating the ring-traveler friction, it is possible to achieve a balance between improved productivity, similar energy consumption, and reasonable traveler wear. Since the yarn productivity is inversely proportional to the yarn twist, yarn productivity can be enhanced by reducing yarn twist with less energy consumption. However, with far less twist, the yarn strength is going to suffer. Therefore, both approaches improve ring yarn yield to some extent, and the level of improvement is subjected to the yarn count, fiber material, spinning conditions, etc. This review provides a clear view of the combination of both approaches to improve yarn productivity and energy efficiency. In the future, it is expected to see more studies of new alternatives which provide the ring spinning process with a cleaner and higher throughput compared to previous or current spinning technologies. • Analysis of limitations of further increasing the throughput of ring spinning. • Review of current approaches by reducing or eliminating ring-traveler friction and reducing yarn twist. • Discussion of yarn spinnability, quality, energy consumption, and production cost. • Suggestions to future research directions towards a cleaner production.}, journal={JOURNAL OF CLEANER PRODUCTION}, author={Yin, R. and Ling, Y.

As a derivative industry of silk manufacturing, spun silk utilizes waste materials generated in different processes of silk production, which is considered as the re-use of silk waste. The spun silk industry is facing several problems now, including environmental pollution, low production efficiency, increased labor intensity, significant material waste, and excessive energy consumption. This study presents an environment-friendly production route to produce mulberry spun silk yarns, by eliminating the gassing process that burns away surface hairs and neps. The gassing process not only generates odors, dust, and gas discharges but also results in significant material wastage and high production cost. The key is a modified ring spinning technology to achieve low yarn hairiness and neps; thus the yarn produced no longer requires gassing. The number of processing steps is also reduced to nine from twelve compared to the traditional silk spinning system. The modified 60 Nm mulberry spun silk yarns show a comparable tenacity of 26.33 cN/tex, evenness of 9.96%, neps (+200%) of 18 per 1 km, and a slightly worse hairiness S3 value of 74 per 100 m, compared with the conventional gassed ones. The plain knitted fabrics made by the modified yarns also reveal a 1.5 grade higher pilling resistance, similar mechanical and thermal properties, and a slightly hairier surface appearance than the conventional ones. The new processing route greatly reduces carbon footprint and achieves significant savings in materials, manpower, and energy, which may shed new light on the industrial manufacturing of mulberry spun silk yarns.}, journal={Journal of Cleaner Production}, publisher={Elsevier BV}, author={Yin, R. and Xiang, Y.F. and Zhang, Z.H. and Tao, X.M. and Gluck, J.M. and Chiu, K. and Lam, W.}, year={2020}, month={Aug}, pages={123690} }

However, their performances have been limited by the employed materials, whose microstructures are not easily designed and controlled. This article proposes a new approach of engineered composite yarns for the actuators. It leads to novel solutions to overcome these difficulties by offering wide design options in material properties and device structures. Here, an engineering design of programmable and thermally-hardening helical composite yarn actuators (HCYAs) with a wide range of operating temperature is exemplified. Polyimide (PI) and polydimethylsiloxane (PDMS) are selected to fabricate HCYAs, achieving tensile actuation of 20.7% under 1.2 MPa from −50 °C to 160 °C and competitive specific work (158.9 J kg-1, four times of natural muscle). With constant tensile deformation, PI/PDMS HCYA nearly tripled the stress from 20 °C to 100 °C. Moreover, it is surprisingly observed an unusual thermal-hardening phenomenon that the tensile stiffness of the PI/PDMS HCYAs increases with the rise of temperature.

However, mathematicians and engineers are more willing to search for analytical solutions because they can obtain more interesting and relevant results. In this paper, an analytical solution of the ring‐spinning equation has been derived using the homotopy perturbation method. The basic idea of this method and a detailed derivation of the analytical solution are also given. The air drag is not considered in order to simplify the procedure. The results show the validity and efficiency in predicting the balloon shape across a wide range of spinning conditions.}, number={9}, journal={Journal of the Textile Institute}, author={Yin, R. and Gu, H.}, year={2011}, month={Sep}, pages={763–766} }

Theoretical equations incorporating yarn elasticity are obtained, which has been ignored by most previous models. This model differs from the earlier ones in that their choice of yarn was perfectly flexible and inextensible; those used here we presume to be more realistic. Discussions in this paper deal with the significance of various yarn elasticity parameters on varying yarn tension and balloon shape. Some results are given, from which the model seems to be very efficient and reliable in the simulation of the ring spinning process. Restrictions on the applicability of the theory are also pointed out.}, number={1}, journal={Textile Research Journal}, author={Yin, R. and gu, H.-B.}, year={2011}, month={Jan}, pages={22–27} }

In the textile industries, the release of a lot of waste wool fibers and their products lead to the idea of regeneration of wool keratin materials. However, the most significant limitation may be the poor fracture resistance of neat keratin films. Greater failure resistance can be achieved by fiber-reinforced matrix when compared to the matrix materials alone. In this article, the fibrils of wool were used as the reinforcements in composite films, which can meet the requirement of biocompatibility. The fibrils morphology was investigated, that is, plain fibrils and fractal-tree structure fibrils. Finite element analysis and tensile tests were used to conduct a direct study on the mechanical properties of composites. It was found that the branched fibrils lead to both higher strength and fracture toughness for the composites than the plain fibrils.}, number={1}, journal={Journal of Composite Materials}, author={Liu, Y. and Yin, R. and Yu, W.-D.}, year={2011}, month={Jan}, pages={113–125} }

However, mathematicians and engineers are more willing to obtain analytical solutions. This paper presents a technique for analytical solution of the dynamics of ring-spinning balloon. Artificial parameter is introduced in order to be used as an expanding parameter. Parameter-expansion method is also used to enlarge the feasible region. Detailed derivation of the analytical solution is presented and the air drag is not considered to simplify the procedure.
