    Abstract: There is a large somatosensory gap between the three-dimensional (3D) printing of clothing and traditional garments due to the limitations (e.g., air permeability and skin-friendliness) of the printing materials. For this reason, the application of traditional textile materials in 3D printing has become a hot topic in the field of 3D printed clothing. Based on the above, this work prepared four kinds of cotton-containing composite solutions and then impregnated thermoplastic polyurethane core yarns in these solutions to obtain four types of 3D printed cotton-containing composite core yarns (3Dp-C-CYs). Afterward, based on the two-dimensional (2D) braiding method, four kinds of cotton-containing 3D printing wires used for fused deposition molding technology were prepared by wrapping low-melting polyester filaments around the different 3Dp-C-CYs. After comparing the printing performance of the four cotton-containing 3D printing wires, the wire containing cotton powders had the best comprehensive performance and was selected to print the cotton-containing 3D printed fabrics. The results showed that the cotton-containing 3D printed fabric has good flatness and contains a large number of cotton powders; in addition, compared with the traditional polylactic acid and acrylonitrile butadiene styrene copolymer 3D printed fabrics, the 3D printed fabric made up of cotton-containing 3D printing wire can provide a closer wearing experience to that of cotton fabric. The 3D printing wire produced by the 2D braiding method offers a new idea for applying traditional textile materials in 3D printing, showing great application potentials in the field of 3D printing of clothing.

    Abstract: Fabric hand is most frequently used by consumers and researchers to evaluate the touch feeling of textiles. Academically, many methods have been developed to characterize it psychologically and physically, and the relationship between the hand attributes of fabrics and their physical properties are well understood. However, in physiological terms, the cognitive mechanism of the brain on different attributes of fabric hand is not clear. Previous studies have shown that the sensory or discrimination information from fabric touch can be detected by the technology of functional magnetic resonance imaging (fMRI). In this study, further fMRI experiments were carried out, attempting to find the relationship between the cerebral cortices of various brain areas and different hand attributes of fabrics. The subtle atlas of Automated Anatomical Labeling (AAL) was used to display and analyze the blood oxygenation level dependent signals completely and conveniently. The results showed that when the subjects touched two samples with distinct fabric hand in a specified way, activation information and the index of the mean signal in every related brain areas can distinguish them, and several brain regions in the AAL atlas are linked to different fabric hand attributes. The technology of fMRI was proved again to be a promising tool for studying the cognitive mechanism of the brain on fabric touch.

    Abstract: It is a universal phenomenon existing in both manufacture and everyday life that fabrics tend to adhere under wet condition. The phenomenon is closely related to the interaction of the fabric surface structure and the liquid. Among the complex structures and numerous varieties of fabrics, the features of typical fabric structures are employed to establish a geometrical model (including structural configuration of spherical protrusion, cylinder, loop, and pore) in order to investigate wet adhesion property under the existence of massive liquid media. Through mechanical analysis on material-liquid bridge system (consisting of fabric material, liquid bridge adhering to the material, and the solid-liquid interface), a quantitative computational theoretical model is built with parameters including critical distance [Formula: see text], radius of the structure R*, apparent receding contact angle [Formula: see text] , wetted sphere angle [Formula: see text], and so on, finding the rules and proposing a series of preferred ranges of regulating structural parameters to effectively achieve desirable fabric wet adhesion property in different circumstances. The research findings could be applied to the scientific prediction and on demand regulation of fabric wet adhesion property. They are of great significance with regard to improving the convenience of fabric wet processing, application properties under wet environments, apparel health and comfort for human body, and so on.

    Abstract: TiO 2 /MgO core–sheath structured nanofibers (NFs) were fabricated through co-electrospinning (i.e., coaxial electrospinning), and then the long TiO 2 /MgO NFs were converted into short TiO 2 /MgO nanorods (NRs) by ultrasonic treatment. Based on the TiO 2 /MgO NRs, two novel technical textiles, that is, a photovoltaic smart textile integrating flexible dye-sensitized solar cells and a photocatalytic functional textile immobilizing photocatalyst, were developed. The effect of the insulating MgO sheath on the semiconducting TiO 2 core was discussed. Compared with the pure TiO 2 NR counterparts, the TiO 2 /MgO NR-based photovoltaic and photocatalytic textiles exhibit better performances. The common reason for the performance enhancements is that the charge recombinations occurring in both photovoltaic and photocatalytic processes are greatly suppressed when TiO 2 is coated by MgO. Finally, the potential applications of these two types of textiles were proposed. This work offers a unique insight into the development of special textiles through the combination of new energy and environmental technologies and traditional textile research.

    Abstract: A modified ring spinning technology has been successfully applied to the production of yarns with reduced twist level and improved performance. Various US cottons and Chinese cottons have been covered in previous studies. In this paper, three combed rovings with different blending ratios of Upland and Extra Long cottons were adopted in a systematic investigation and evaluation on a fine modified ring yarn produced on a new modified spinning system that was developed to reduce the imperfections of fine yarns. The potentially important spinning parameters were proposed and their individual and interaction effects of spinning system parameters on the properties of fine modified ring yarn were quantitatively examined using the response surface methodology. Then with the optimum parameters, physical properties of the yarns and their knitted fabrics produced from three rovings were evaluated by comparing them with the conventional ones. Experimental results showed that yarns produced in the new modified spinning system had reduced imperfections; at low twist levels, fine modified yarns and resultant fabrics also showed improved performance. Moreover, properties of fiber materials and roving quality influenced the properties of modified yarns and knitted fabrics.

    Abstract: Liquid transport in porous materials is affected significantly by the geometry of the non-uniform capillaries. In this study, an N-section lotus-rhizome-node-like non-uniform capillary model was for the first time proposed based on the plane Poiseuille flow and capillary pressure equation to investigate the liquid transport in porous fibrous media. Normalized total flow time of the non-uniform capillary was obtained as a function of the height and width ratio between the converging and diverging nodes and their total number. The results indicated that the velocity of liquid transport greatly depended on the number of nodes in a certain liquid transport length. The non-uniform capillaries with frequent alterations between converging and diverging nodes have low liquid transport efficiency. The thick capillary exhibits fast liquid transport efficiency in those capillaries with the same self-similar geometry. The model was verified using polypropylene filament yarns and different liquids. The results agreed well with the theoretical prediction. This work not only provides a deeper understanding of liquid transport inside porous fibrous media with non-uniform capillaries, but can also guide the novel design and optimization of functional fibrous materials.

    Abstract: The present study was carried out with a new approach to evaluating the comfort of fabric contact pressure. Functional magnetic resonance imaging technology was conducted to monitor brain response when a comfortable fabric contact pressure, according to the subjective evaluation, was applied to the skin surface of the lower human chest. After a strict method of calibration with a family-wise error check analysis, the study we performed revealed the right secondary somatosensory cortex appeared prominently positively activated under a comfortable fabric pressure state. This suggested the secondary somatosensory cortex brain region, particularly the right secondary somatosensory cortex, was probably the characteristic brain region for fabric comfort perception. A reasonable explanation was that proper contact pressure facilitated the serial information flow from the primary somatosensory cortex to the secondary somatosensory cortex, and comfortable touch stimulated the firing of A-beta afferent nerves.

    Abstract: A conical winding formation and tension control system was proposed in the doubling operation based on the yarn guide mode of a single spindle in this study. Conical winding formation realized the radial unwinding of wound package. An overfeed mechanism was introduced to achieve closed-loop control of yarn tension. The overfeed wheel was driven by a brushless Direct Current motor. The tension control system combined a Proportion Integration Differentiation controller with a radial-basis-function neural network, whose purpose was to meet the control requirements of the brushless DC motor. This system consisted of three main steps: Firstly, the radial-basis-function neural network was used to identify the system online. Secondly, the gradient descent method was used to adjust the node weight, center vector, and baseband width. Finally, incremental PID parameters online were adjusted according to the identified Jacobian information. A mathematical model of a control system was established in Matrix Laboratory. An experimental platform was designed for doubling winder to compare the control effects of Radial-basis-function-PID with traditional PID. The simulation results showed that the RBF-PID had a smaller overshoot of yarn tension, shorter adjustment time, and smaller steady-state error compared with the traditional PID controller in doubling operation by simulating the mathematical model. Experimental results showed the RBF-PID controller had good performance and stability and could be applied to yarns with different average linear velocity, yarn counts and strands . The yarn tension fluctuation will not exceed ±3% of the target value when the experimental materials and the cone angles are unchanged.
