  • effect of co laser treatment on the Fabric Hand of cotton and cotton polyester blended Fabric
    Polymers, 2017
    Co-Authors: On-na Hung, Chi-wai Kan
    Abstract:

    This paper compares the impact of laser treatment on cotton and cotton/polyester blended Fabric Hand properties, using the PhabrOmeter system. Five Fabric Hand properties, namely, stiffness, smoothness, softness, wrinkle recovery rate, and drapability, were obtained, and it was proven that laser treatment could be successfully used to change the Fabric Hand. In the case of pure cotton woven Fabrics, the Fabrics were found to have better drapability and wrinkle recovery after laser treatment. In cotton/polyester blended Fabrics, stiffness was found to be relatively higher after laser irradiation.

  • a comparison study of Fabric objective measurement fom using kes fb and phabrometer system on warp knitted Fabrics Handle smoothness stiffness and softness
    World Academy of Science Engineering and Technology International Journal of Chemical Molecular Nuclear Materials and Metallurgical Engineering, 2014
    Co-Authors: Kayan Yim, Chi-wai Kan
    Abstract:

    Authors : Ka-Yan Yim, Chi-Wai Kan Abstract : This paper conducts a comparison study using KES-FB and PhabrOmeter to measure 58 selected warp knitted Fabric Hand properties. Fabric samples were selected and measured by both KES-FB and PhabrOmeter. Results show differences between these two measurement methods. Smoothness and stiffness values obtained by KES-FB were found significant correlated (p value = 0.003 and 0.022) to the PhabrOmeter results while softness values between two measurement methods did not show significant correlation (p value = 0.828). Disagreements among these two measurement methods imply limitations on different mechanism principles when facing warp knitted Fabrics. Subjective measurement methods and further studies are suggested in order to ascertain deeper investigation on the mechanisms of Fabric Hand perceptions.

  • consistency and reliability of untrained consumers perceptions of Fabric Hand of men s suiting
    Textile Research Journal, 2016
    Co-Authors: Xianyi Zeng, Ludovic Koehl, Z Xue, L Shen
    Abstract:

    The current study is aimed to analyze the consistency and reliability of untrained consumers' perception of Fabric Hand. A group of untrained assessors are recruited to evaluate the Fabric Hand of a number of suit Fabrics through free sorting and rating experiments. Two statistical methods have been used to measure the consistency between the sorting and rating data of the assessors in replicated sessions. According to the types of data obtained from different evaluation procedures, different multidimensional scaling techniques are applied to investigate the tactile dimensions, and further on the assessors' preference regarding the total Hand of the samples for the end-use of men's suit. It is found that simple sorting and rating procedures are efficient methods for acquiring consistent sensory results from untrained assessors on a relatively large number of textile products, and that multidimensional scaling is an effective technique for interpreting the obtained non-descriptive sensory data.

  • extracting Fabric Hand information from visual representations of flared skirts
    Textile Research Journal, 2014
    Co-Authors: Xianyi Zeng, Ludovic Koehl, Zhebin Xue, Yan Chen
    Abstract:

    In online transactions of textile products, Fabric Hand was thought to be inaccessible to consumers. Recently, much effort has been made to study the feasibility of providing consumers with a real sense of Fabric through a virtual experience. The current paper proposes to extract Fabric Hand information from the perspective of visual perception. Two sensory experiments are conducted according to the standardized sensory evaluation procedures on a set of representative textile Fabrics by two trained panels. The first experiment is aimed to measure how much Fabric Hand can be perceived through Fabrics’ visual displays. On the basis of the positive results obtained, the second experiment is carried out to further investigate the interactive mechanism between samples’ visual features and their tactile properties. A novel algorithm based on rough set theory and fuzzy set theory is proposed in order to quantitatively measure relations between different sensory information.

  • Interaction of textile parameters, wash-ageing and Fabric softener with mechanical properties of knitted Fabrics and correlation with textile-Hand. I. Interaction of textile parameters with laundry process
    Fibers and Polymers, 2011
    Co-Authors: Gaurav Agarwal, Ludovic Koehl, Anne Perwuelz, Kenneth S. Lee
    Abstract:

    This is a study of the influence of repeated laundering and the use of Fabric softener in the context of mechanical properties of Fabrics with respect to textile parameters. In the large competitive market of Fabric softener, the Fabric softener producers claim benefits for Fabric Hand as well as the mechanical properties of textiles. The main aim of this study is to investigate the influence of ageing and the use of Fabric softener on the mechanical properties of textiles during their cradle to grave life with respect to fibre type, fibre fineness, knitting construction and number of wash cycles. The low stress mechanical properties were evaluated by means of the Kawabata Evaluation system for Fabric (KES-F) and Universal Surface Tester (UST). The tensile, shear, bending, compression and surface properties and changes in these parameters due to wash-ageing and the use of Fabric softener during laundry were evaluated. These mechanical properties or combinations of them are the deciding factors for comfort aspects of apparel during wear. Hence, these mechanical properties need to be correlated with the sensory attributes. In Part I, we examine the change in mechanical parameters due to wash-ageing and the use of softener, while Part II deals with Fuzzy-Logic modelling to correlate these mechanical parameters with sensory attributes.

  • sensory study of knitted Fabrics that have gone through washing cycles with domestic softener part i establishment of a panel and assessment thereof
    Fibres & Textiles in Eastern Europe, 2011
    Co-Authors: Gaurav Agarwal, Ludovic Koehl, Anne Perwuelz
    Abstract:

    This study involved the sensory evaluation of knitted textiles which have gone through different domestic laundering treatments with respect to whether their sensory attributes or a combination of different measured sensory attributes can best predict the preference of consumers in the aspect of comfort . The textile consumer always has specific preferences which are related to textile properties at the time of purchasing textiles and also to the perception of how long lasting these properties will be. In the large competitive market of softeners, all softener producers claim the improvement of Fabric Hand as well as the mechanical properties of textiles. The main aim of this study is to find the important sensory parameters enhanced by the use of softener during washing and the impact of repeated washing on sensory attributes. The study is based on cationic softener (rinse cycle type). We also examined the change in the Handle of Fabric using the Fabric life cycle. The change in the Handle of Fabric after washing is unavoidable because of strong mechanical action during washing, but it can be improved with the use of domestic softeners during the rinse cycle. In Part I, we established a panel for the sensory evaluation of knitted Fabrics that have gone through the ageing of washing cycles with/without the use of Fabric softener. The panel assessed the Fabrics using criteria defined by the author. In part II, we will discuss the influence of ageing during the washing cycle and the use of Fabric softener on sensory properties.

  • A linguistic multi-criteria group decision support system for Fabric Hand evaluation
    Fuzzy Optimization and Decision Making, 2009
    Co-Authors: Yijun Zhu, Xianyi Zeng, Ludovic Koehl, Guangquan Zhang
    Abstract:

    Fabric Hand evaluation (FHE) is the main measure in textile material selection for fashion design and development. Fabric Hand evaluation requires considering multiple evaluation aspects/criteria by a group of evaluators. Some Fabric features can also be measured using instruments. The evaluation often uses linguistic terms in the weights of criteria, and the weights and judgments of evaluators. To support a FHE-based material selection, this study first develops a Fabric Hand-based textile material evaluation model. It then proposes a human-machine measure integrated fuzzy multi-criteria group decision-making method. A software tool is also developed, which implements the proposed method and is applied in Fabric Hand-based textile material evaluation.

  • structure function analysis of nonwoven cotton topsheet Fabrics multi fiber blending effects on fluid Handling and Fabric Handle mechanics
    Materials, 2018
    Co-Authors: Michael W Easson, Judson V Edwards, Ningtao Mao, Chris Carr, David Marshall, Elena Graves, Michael Reynolds, Andres Villalpando, Brian Condon
    Abstract:

    Greige cotton (GC) has attracted interest in recent years as an eco-friendly, functional fiber for use in nonwoven topsheet materials. GC imparts favorable fluid management and sensorial properties associated with urinary liquid transport and indices related to comfort in wearable incontinence nonwovens. Nonwoven GC has material surface polarity, an ambient moisture content, and a lipid/polysaccharide matrix that imparts positive fluid mechanic properties applicable to incontinence management topsheet materials. However, a better understanding of the connection between functionality and compositional aspects of molecular, mechanical, and material property relations is still required to employ structure/function relations beyond a priori design. Thus, this study focuses on the relation of key indices of material fluid and sensorial functions to nonwoven topsheet composition. Greige cotton, polypropylene, bleached cotton, and polyester fiber blends were hydroentangled at 60, 80, and 100 bar. Greige cotton polypropylene and bleached cotton were blended at ratios to balance surface polarity, whereas low percentages of polyester were added to confer whiteness properties. Electrokinetic and contact angle measurements were obtained for the hydroentangled nonwovens to assess surface polarity in light of material composition. Notably, materials demonstrated a relation of hydrophobicity to swelling as determined electrokinetically by Δζ, ζplateau, and contact angles greater than 90°. Subsequently, three blended nonwoven Fabrics were selected to assess effects on fluid management properties including topsheet performance indices of rewet, strikethrough, and fluid Handling (rate and efficiency of transport to the absorbent core). These materials aligned well with commercial topsheet fluid mechanics. Using the Leeds University Fabric Handle Evaluation System (LUFHES), the nonwovens were tested for total Fabric Hand. The results of the LUFHES measurements are discussed in light of fiber contributions. Fiber ratios were found to correlate well with improvement in softness, flexibility, and formability. This study provides insights that improves the understanding of the multifunctional properties accessible with greige cotton toward decisions valuable to selecting greige cotton as an environmentally friendly fiber for nonwoven topsheets.
