  • A statistical analysis of low-stress mechanical properties of warp-knitted fabrics:
    Textile Research Journal, 2016
    Co-Authors: Ka Yan Yim, Chi Wai Kan
    Abstract:

    Fabric hand is an indispensable characteristic for the selection of fabric and product development and the buying consideration for manufacturers and consumers. However, there is little comprehensive work on the hand feel property of warp-knitted fabrics due to the mainstream natural fibers (cotton, wool and silk) and other fabric structures (woven, weft-knitted and nonwoven). The increasing potential for the wide variety of applications and development of warp-knitted fabrics is not only because its fabric hand gives better determination for fabric marketing, but also because it provides extensive scope for fabric performance and appearance. This paper reports an experimental study on the integrated fabric hand behavior of a series of warp-knitted fabrics made for various apparel applications, such as sportswear, lingerie and leisure wear. These 105 fabrics were produced by varying different physical parameters, including fabric weight and fabric thickness. The Kawabata Evaluation System for Fabric (KES-...

  • Low-Stress Mechanical Properties of Cotton Fabric Treated with Titanium Dioxide-Catalyzed Wrinkle-Resistant Finishing
    Journal of Natural Fibers, 2016
    Co-Authors: Chin-kuen Poon, Chi Wai Kan
    Abstract:

    ABSTRACTThere are five low-stress mechanical properties (tensile, shearing, bending, surface, and compression) that affect the fabric handle. Dimethyloldihydroxyethyleneurea (DMDHEU) is a conventional agent for imparting wrinkle-resistant properties to cotton fabric. DMDHEU-crosslinked fabrics provide excellent wrinkle recovery properties but may affect the fabric hand. In this study, fabrics treated for wrinkle resistance were assessed by the Kawabata Evaluation System for Fabric (KES-F), which objectively evaluates low-stress mechanical properties of textiles. Four curing temperatures, 110, 130, 150, and 170oC, were used in the wrinkle resistant finishing and effects of different concentrations of titanium dioxide (TiO2) used as co-catalyst were also studied. It was found that changes in curing temperature (from 110 to 170oC) have an obvious effect on tensile, shearing and bending properties. Surface and compression properties, however, did not show a significant variation. Moreover, the use of TiO2 par...

  • Determination of Surface Properties of Paper Towels with KES-F System
    Applied Mechanics and Materials, 2016
    Co-Authors: Chi Wai Kan, Maggie Hoi Man Leung, Rattanaphol Mongkholrattanasit
    Abstract:

    In this study, 12 commercially available paper towels were collected from the market. Their shearing properties were evaluated by Kawabata Evaluation System for Fabric (KES-F). Three properties namely: (i) coefficient of friction (MIU), (ii) deviation of MIU (MMD) and (iii) geometric roughness (SMD). Experimental results revealed that the surface properties varied within the products. When different properties were correlated, it was found that there was not significantly relationship between MIU, MMD and SMD. However, weight and thickness had well statistically relationship to SMD.

  • Using KES-F System for Determining the Bending Properties of Paper Towels
    Applied Mechanics and Materials, 2016
    Co-Authors: Chi Wai Kan, Maggie Hoi Man Leung, Rattanaphol Mongkholrattanasit
    Abstract:

    12 commercially available paper towels were collected from the local market and studied in this paper. Kawabata Evaluation System for Fabric (KES-F) was used for evaluating their bending properties. Two bending properties namely: (i) bending rigidity (B) and (ii) bending moment (2HB) were evaluated. Experimental results indciated that the bending properties varied within the products. B was used as the key property for discussing the bending properties of paper towels. When the correlations of different bending properties were investigated, it was found that no significant was found between B and 2HB. However, there was significant statistically relationship between weight and B but no relationship between thickness and B. With the use of the results, the product developer could improve the bending properties of the paper towels.

    Co-Authors: C. K. Chan, X.y. Jiang, K.l. Liew, L.k. Chan, Wai Keung Wong, M.p. Lau
    Abstract:

    Abstract Kawabata Evaluation System (KES) is the first advanced and unique solution of user friendly testing of fabric mechanical properties. The information provided by this System can enable remedial/preventive action to be taken in garment manufacturing so as to guarantee production efficiency and product performance since the mechanical properties of fabrics not only govern the performance of fabric products but also influence garment making operations. In the present research, this System was adopted to investigate the mechanical properties of uniform fabrics currently in use on the basis of 12 different commercial types of uniform materials obtained from different sources. All determination of the 16 parameters describing fabric mechanical properties was undertaken according to the prescribed procedure and required condition. The obtained results will surely help to identify the design criteria for uniform clothing so as to produce high-quality career uniforms.

  • Tactile Fabric Comfort Prediction Using Regression Analysis
    2015
    Co-Authors: Les M. Sztandera
    Abstract:

    Abstract:- In this paper we explore complex relationships between mechanical and sensory properties of fabrics, and the perceived tactile comfort. Mechanical properties, measured objectively by Kawabata Evaluation System for Fabrics (KES-FB), and handfeel properties, measured subjectively by sensory expert panel, are related to the tactile comfort of fabrics using statistical regression approaches. A universe of 48 fabrics is examined to analyze and map the relations. The initial 17 mechanical and 17 handfeel parameter sets were reduced to 4 and 5 properties, respectively. Adjusted R 2 values were 0.657 for mechanical and 0.863 for handfeel parameters, reflecting sound goodness-of-fit measures, and providing reasonable ways for prediction of tactile fabric comfort from mechanical and handfeel parameters. Key-Words: tactile perception, fabric mechanical properties, regression analysis, textile property analysis

  • Sensory perception of fabrics: analysis of tactile comfort properties using statistical and artificial intelligence techniques
    2007
    Co-Authors: B. Karthikeyan, Les M. Sztandera
    Abstract:

    The relationship between mechanical and sensorial properties of textile materials, with perceived comfort is complex and non-linear. A System to analyze the aforementioned relationship using Artificial Intelligence (AI) tools is developed. Since the number of parameters that influence perceived sensation is beyond the capability of any existing model, a model-free algorithm based on a biological System of perception with the aid of neural network mapping is attempted. Mechanical properties - measured objectively using the Kawabata Evaluation System for Fabrics (KES-F) and HandFeel properties - measured subjectively using a sensory expert panel is related to the tactile comfort sensation of textile materials using AI tools. Also, brief comparison with a linear statistical approach is presented.

  • Fabric objective measurement of the plasma-treated cotton fabric subjected to wrinkle-resistant finishing with BTCA and TiO2 System
    Fibers and Polymers, 2011
    Co-Authors: Y. L. Lam, Chi Wai Kan, Cwm Yuen
    Abstract:

    Handle is an important factor when designing the end-uses of fabric as it is also a critical factor for purchasing decision. In the present study, the Kawabata Evaluation System for Fabrics (KES-F) was used for measuring the fabric handle of BTCA-TiO2 treated cotton fabric with or without plasma pre-treatment. The results revealed that the BTCA-TiO2 treated cotton fabrics without plasma pre-treatment had a negative effect on tensile, shearing, compressional, and surface properties while the bending properties were improved. On the other hand, the plasma pre-treatment improved the tensile and compressional properties, but not the bending, shearing, and surface properties.

  • Low stress mechanical properties of plasma-treated cotton fabric subjected to titanium dioxide coating:
    Textile Research Journal, 2011
    Co-Authors: Y. L. Lam, Chi Wai Kan, Chun Wah Yuen
    Abstract:

    The titanium dioxide coating together with plasma pre-treatment improved the wrinkle recovery property of cotton fabrics, but, at the same time, may worsen the fabric handle which is an important factor when designing the end uses of fabric, as handle of fabric is also a critical factor for purchasing decisions. In this study, the Kawabata Evaluation System for Fabrics measures the sensory properties of plasma- and/or titanium dioxide-treated cotton fabrics. The low stress fabric surface correlates closely with mechanical properties; the change in fabric stiffness, thickness, extensibility, appearance retention, surface smoothness or bulkiness may affect each other. The results found that the titanium dioxide treatment had a negative effect on tensile properties, compressional properties and surface friction and variation, while shearing and bending properties were improved by the treatment. In addition, plasma treatment improves all sensory properties except surface friction and variation.
