    Abstract: Warp-knitted spacer fabrics for cushion products are in contact with different parts of human body. Surface shapes of most contacting parts can be simplified as spherical caps, while there are few reports on relationship between sphere diameter and compression property of spacer fabric. Therefore, the main content dealt with in the paper was to conduct spherical compression and simulation analysis of warp-knitted spacer fabrics. Five spherical indenters were selected and three compression indices were featured. Comparisons of compression indices results of spacer fabrics amongst five spherical indenters exhibited good relations. Moreover, spherical compression behavior was simulated by finite element method to better understand the mechanism of spherical compression deformation of warp-knitted spacer fabrics. The results that relative errors of the compression indices were all small showed a good accordance between theoretical and experimental results; then, stress distribution and displacement evolutions were analyzed to discover deformation mechanism of spacer filaments compressed. It is effective to simulate the spherical compression performance between different parts of human body and spacer fabric.

    Abstract: Flexible and durable electrically driven heaters (EDHs) was prepared by using silver nanowire/polydopamine modified cotton fabric (AgNW/PDA-C) as Joule heat generator and polydimethylsiloxane (PDMS) as stretchable matrix.The electric property of the EDHs was investigated, and it can show excellent electrical property and stability. The EDHs can be seen from the SEM morphology that cotton fabric was well protected by the PDMS and has good conductive network. The EDHs also exhibit excellent electrothermal performance under applied voltage. At low-voltages, it can quickly reach satisfactory steady-state temperatures that meet the needs of wearables. By improving the electrothermal model, it can be verified that there is a quadratic function relationship between electric power and steady-state temperature. Under cyclic voltage and bending tests, the EDHs can well maintain steady-state temperature and exhibit excellent dynamic and static electrothermal performance.

    Abstract: Polylactic fiber (PLA) is a new environment‐friendly fiber and has been produced by different plants with wide application, while there are few studies on the difference of the structure and property of PLA fibers produced from these plants in China. The main content in present article is to conduct elementary analysis, gas chromatography mass spectrum, IR spectroscopy, ultraviolet, X‐ray, differential scanning calorimetry (DSC), TG, SEM, and tensile tests to obtain the common structure and properties of PLA fibers and to prove that there are no significant difference between the 13 kinds of PLA fibers made by 13 plants in China. The elementary analysis method is used to test the contents of C, H, and O elements, and it has good accordance with the theoretical results. Gas chromatography mass spectrum method proves that the functional groups of PLA fiber are lactide and acetaldehyde as well as 2,3‐pentanedione. IR spectroscopy depicts that significant absorbing peaks exist as CO, CO, OH within absorbing wavelength zones. There are no characteristic absorbing peaks of ultraviolet spectrum. Crystallinity and orientation degree in full wave at half maximum and in area are calculated based on X‐ray. The peak melting point and pyrogenation peak point are obtained by DSC and TG testings. The tensile property and the surface morphology by SEM are conducted and some typical faults in the surface are observed. In addition, the coefficient of variance of these experimental results between 13 kinds of PLA fibers show that their structure and properties are similar. © 2012 Wiley Periodicals, Inc.

    Characterization of plantar press-comfort performance of warp-knitted spacer fabrics

    Abstract: The main content dealt with in this paper was to present an objective method to evaluate the plantar press-comfort performance of warp-knitted spacer fabrics. It aimed to explain the plantar press-comfort performance of spacer fabric by the compression property and structure parameters of spacer fabric. The compression indexes (compression work, recovery work, hysteresis work and maximum compression force) and structure parameters (diameter and thickness) were utilized to classify the plantar press-comfort performance of warp-knitted spacer fabrics by regression analysis and the K-means cluster method. In order to verify the validity, subjective judgments were also made and compared with the objective K-means cluster method. The experimental results showed that a good correlation existed between the subjective judgment method and objective cluster method. This demonstrates that the compression indexes featured, from spherical compression force–displacement curves and structure parameters, can be utilized to characterize the plantar press-comfort performance of warp-knitted spacer fabrics and is effective in obtaining the fabric evaluation score of plantar press-comfort performance.

    In: Textile Research Journal, SAGE Publications, Vol. 88, No. 7 ( 2018-04), p. 790-799
    Abstract: The main content dealt with in this paper was to carry out a theoretical analysis of the damping property of spacer fabric used as cushion materials. A free vibration test was conducted and the corresponding model was established based on a single-degree-of-freedom (SDOF) system by considering the viscous–elastic behavior of spacer fabric during free vibration. Displacement–time curves of spacer fabric were calculated by a second-order integral of acceleration and time curves recorded by an accelerator sensor. Then, vibration indexes, including the damping ratio, damping coefficient, logarithmic decrement and free vibration period, were featured based on a SDOF model. The experimental results of damping ratio and displacement–time curves were compared with the theoretical results. It indicated that the vibration model was effective to characterize the free vibration of spacer fabric. Moreover, the effects of different structural parameters, including thickness, filament diameter, area density and inclination angle and arrangement of spacer filaments, of the spacer fabric on the damping property were also investigated. This is helpful to better design spacer fabrics with a good damping property.

    Analysis of the mechanical properties of double arrowhead auxetic metamaterials under tension

    In: Textile Research Journal, SAGE Publications, Vol. 90, No. 21-22 ( 2020-11), p. 2411-2427
    Abstract: In order to study the deformation behavior of double arrowhead (DAH) auxetic metamaterials under different forces with different directions as well as the effects of the geometry parameters on the Poisson's ratio, this paper assembled an advanced researching method by combining the industrial design of SolidWorks software, the finite element analysis of Abaqus software and three-dimensional printed technology. Results show that the DAH structure expanded in the direction perpendicular to the force first and contracted with the strain increasing when it was pulled by the uniaxial force, no matter which direction the force is applied. Besides, the auxetic effect of the DAH structure under the tensile force in the X direction is longer than that under the tensile force in the Y direction. It is more resistant to compression when the DAH structure is subjected to transverse tensile forces than when it is subjected to longitudinal tensile forces. The angle of the V-shaped short truss has a significant impact on the negative Poisson's ratio of the DAH structure, while the angle of the V-shaped long truss angle has little influence on its auxetic performance. Specifically, the smaller the angles, the better the auxetic effect.

    Abstract: In this paper, a multilevel fuzzy comprehensive evaluation (FCE) model consisting of tactile comfort and four primary handle characteristics (FPHCs) is developed. The physiological perceptions of 30 home textile fabrics were predicted, to verify the practicability of the FCE model and the reliability of the objective measurement based on the self-developed Quick-Intelligent Handle Evaluation System (QIHES). Moreover, comparisons between the FCE model and subjective evaluation of the FPHCs and total handle value (THV) were investigated. The results showed that the values of the coefficients of determination ( R 2 ) and the slopes of linear correlation functions were approximate to 1, which revealed that the results of the FCE model and subjective evaluation were highly consistent, and the FCE model established was accurate. In addition, the performance of the soft fabrics depends on the combined effect of the properties of three directions. It has been confirmed that the fullness, stiffness and roughness are important factors that affect THV together. Thus, the FCE method based on the QIHES measurement was demonstrated to be effective and reliable, could be applied for assessing tactile comfort and estimating human feel when touching textiles and soft materials.

    Theoretical and experimental investigations on the effects of friction, bending rigidity, extensibility, and Poisson's ratio on fabric tensile properties

    Abstract: A three-point tensile model that consists of a noncontact model and a modified capstan model of contact sections, including coupling effects of factors, is established in this study. The tension ratio calculated using the Runge–Kutta method increases along with the extensibility, surface friction coefficient, and radius ratio and is inhibited by the power-law friction ([Formula: see text]). Moreover, the theoretical model in a case with all the factors and frictional modification shows high accuracy with the actual test of the quick-intelligent handling evaluation system, and the Poisson's effect can be negligible, especially with the power-law friction. It has been confirmed that greater surface roughness and thickness (lower radius ratio) with worse extensibility result in tighter fabric tensile properties. Therefore, this work can provide theoretical guidance for the measurement of fabric tensile properties and the evaluation of practical application of fabrics.
