  • abrasion resistance of thermally bonded 3d nonwoven Fabrics
    Wear, 2007
    Co-Authors: X. Y. Wang, Z. Dong, R H Gong, Iris Porat
    Abstract:

    Employing the established standard Martindale abrasion method, the abrasion resistance of the three-dimensional nonwoven filter samples produced using the recently developed air laid web formation process and through-air thermal bonding process and the commercially available polypropylene (PP)/polyester (PET) (sheath/core) bi-component staple fibre as raw material, has been evaluated. Results obtained indicated that there are two failure forms for the thermally bonded nonwoven samples during the abrasion testing, the peeling of the fibre PP sheath and the pilling forming and breaking off. The process parameters, including the bonding temperature, dwell time and hot air velocity and Fabric Weight clearly affect the abrasion resistance of the thermally bonded nonwoven filter samples. These effects could be correlated with the thermal oxidative degradation of the fibre PP sheath during the thermal bonding process and the compactness of the resulting samples.

  • Compression creep behaviour of polyester needle-punched nonwoven Fabrics
    Journal of The Textile Institute, 2012
    Co-Authors: Sanjoy Debnath, M. Madhusoothanan
    Abstract:

    This present study deals with the compression creep behaviour of polyester needle-punched nonwoven Fabrics. Polyester fibres of three different cross-sectional shapes (round, circular hollow and trilobal) have been selected for this study. An instrument has been designed and Fabricated to measure the compression creep property of needle-punched Fabrics. The effect of duration of compression load, Fabric Weight, fibre cross-sectional shapes and reinforcing material on percentage compression creep has been studied. It has been observed that initially, compression creep decreases rapidly and with increase in time, decrease of percentage creep becomes minimal. After about 8500 min of application of the same compression load, no change in compression creep is noticed. The percentage compression creep decreases with the increase in Fabric Weight irrespective to fibre cross-sectional shapes of polyester needle-punched nonwoven Fabrics. Trilobal cross-sectional Fabric shows maximum amount of percentage compressio...

  • Compression creep behaviour of jute-polypropylene blended needle-punched nonwoven
    Textile Research Journal, 2012
    Co-Authors: Sanjoy Debnath, M. Madhusoothanan
    Abstract:

    This paper discusses the compression creep behaviour of jute-polypropylene blended needle-punched nonwoven. It is essential to know the compression creep behaviour of the needle-punched Fabrics too, because of their various applications like geotextiles and carpets. Needle-punched Fabric samples were prepared based on the three factors, three levels Box Behnken design of experiment to study the individual as well as interaction effects of process parameters of Fabric Weight, needling density and blend proportion of jute and polypropylene fibre blend on Fabric thickness and compression creep. This study reveals that the initial thickness of Fabric decreases prominently with the increase in needling density at low Fabric Weight and has hardly any effect at high Fabric Weight (450 g/m2). However, around 43% increase in Fabric thickness occurs at high jute content level (60%). At low Fabric Weight, the effect of the needling density on compression creep is highly prominent when polypropylene content is more t...

  • Studies on compression properties of polyester needle-punched nonwoven Fabrics under dry and wet conditions
    Journal of Industrial Textiles, 2012
    Co-Authors: Somnath Debnath, M. Madhusoothanan
    Abstract:

    In this article, the effects of Fabric Weight, fiber cross-sectional shapes (round, hollow, and trilobal), and presence of reinforcing material on the compression properties (initial thickness, percentage compression, percentage thickness loss, and percentage compression resilience) under dry and wet conditions of polyester needle-punched industrial nonwoven Fabrics are presented. It has been found that initial thickness of the Fabric decreases under wet condition for both with and without reinforcing materials. The percentage thickness loss values are higher under wet condition in case of samples with reinforcing material compared to samples without reinforcing material. In the presence of reinforcing material, the trilobal cross-sectional Fabric samples show the highest increase in thickness loss under wet condition followed by round and hollow cross-sectional polyester needle-punched nonwoven samples. Compression resilience is the highest in case of round cross-sectional Fabric without reinforcing material under wet condition than Fabric with reinforcing material. The initial thickness increases, and percentage compression and thickness loss decrease with the increase in Fabric Weight irrespective of fiber cross-sectional shapes both in dry and wet conditions. The initial thickness, percentage compression, and percentage compression resilience of the Fabric decrease but percentage thickness loss increases under wet condition compared to the dry condition irrespective of the fiber cross-sectional shape. Compared to other cross-sectioned polyester samples, the hollow cross-section samples undergo very less consolidation under wet condition due to their consolidated structure. There is a drastic drop in compression resilience and increase in thickness loss under wet condition than in dry state irrespective of the fiber cross-sectional shape.

  • Thermal resistance and air permeability of jute-polypropylene blended needle- punched nonwoven
    2011
    Co-Authors: Sanjoy Debnath, M. Madhusoothanan
    Abstract:

    Thermal resistance and air permeability of needle-punched nonwoven Fabric made from jute and polypropylene blends have been studied using the Box and Behnken factorial design to observe the effect of Fabric Weight, needling density and blend proportion on thickness, thermal resistance, specific thermal resistance, air permeability and sectional air permeability. Correlation matrix and cluster analysis have also been used to understand the relationship and grouping behaviour of the dependent and independent variables. It is observed that the thermal resistance and thickness increase but air permeability and sectional air permeability decrease significantly with the increase in Fabric Weight at all levels of jute contents. Significant ( p < 0.05000) negative correlations r = – 0.67 and r = – 0.61 exist between needling density & thermal resistance and needling density & specific thermal resistance respectively. The highest thermal resistance and specific thermal resistance have been obtained at 430 g/m 2 Fabric Weight and 150 punches/cm 2 needling density. All dependent variables are highly influenced by Fabric Weight (Euclidean distance ~ 560) which is a different cluster identity.

  • Thermal insulation, compression and air permeability of polyester needle-punched nonwoven
    2010
    Co-Authors: Sanjoy Debnath, M. Madhusoothanan
    Abstract:

    The normal round, circular hollow and trilobal cross-sectional shaped polyester fibres have been used to prepare needlepunched nonwoven Fabrics for technical textile application. Effects of Fabric Weight and fibre cross-sectional shapes on thermal insulation value (TIV), Fabric thickness, density, percentage compression, air permeability and sectional air permeability (SAP) have been studied. Comparison between Marsh and plate methods of TIV measurement has also been studied along with the inter-relation and grouping of parameters using correlation matrix and cluster analysis approach respectively. The TIV, thickness, density, air permeability and SAP fall under different sub-cluster but all these parameters are dependent on Fabric Weight. Plate method of TIV measurement is preferred over Marsh TIV measurement because of the easy preparation of samples and the reason that the samples retain their original properties and it gives more accurate results. Trilobal Fabric sample shows highest TIV, thickness and percentage compression followed by regular and hollow polyester needle-punched Fabrics. Thermal insulation value, thickness and density of the Fabric increase but percentage compression, air permeability and SAP decrease with the increase in Fabric Weight. The Fabric thickness is significantly correlated with Fabric Weight and TIV. Fabric Weight versus air permeability and Fabric density versus SAP are negatively correlated with significant correlation coefficient.
