Investigation and Modeling of Mechanical and Comfort Properties of Spacer Knitted Fabric using Artificial Neural Network Ehsan Ghorbani ehsantextile84@yahoo com Date of Submission February 19 2012 Department of Textile Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiMohammad Zarehbini Esahani zarrebini @cc iut ac irAbstractSpacer fabrics are dual layer structure comprise of two separate outer and one middle layers Themonofilaments of middle layer connect the two outer layers together Various fabric formation techniquescan be used in manufacture of spacer fabrics Incorporation of the middle layer not only imparts uniquetransfer properties to the fabric but also enhances fabric impact absorption capacity These unique propertieshave resulted in extensive application of spacer fabrics in various areas such as automotive medical technical and industrial textiles geotextile sports textiles and apparels Additionally these fabrics due totheir unique properties have replaced Polyurethane or Neoprn foams in various applications Orientation offibers both along the surface and thickness of spacer fabrics not only creates a three dimensional structurebut also imparts a very high degree of reversible compressibility As far as properties such as heat treansfer moisture transfer and air permeability are concerned spacer fabrics are much superior in these respects incomparison to conventional flat textile fabrics Upon exertion of pressure the knitted loops constituting thefabric are deformed the deforming energy is absorbed by the loop and is transferred to the adjacent loops Upon removal of pressure the deformed loops return to their initial configuration Spacer fabrics due to theirthree dimensional structure high porosity and air permeability and unique heat and moisture transfer abilitycan easily prevent moisture formation on the skin These together with dynamic air circulation within thefabric constitute the requirements of fabric comfort which is of paramount importance in various applicationsof textiles In this study a model using artificial neutral network technique was developed The ideal networkwas found by manipulation of network topology epoch and activation functions This model predicts transferand compression properties of the spacer fabrics using parameters such as fabric mass composition porosityand thickness as inputs In order to train the network specifications of 30 commercially available samples ofspacer fabrics were used to train the model The model was tested by comparison of the theoretical andexperimentally obtained set of results for further five commercially available samples of spacer fabric Adiscrepancy of less than 10 was found to exist between the two sets of results This confirmed the validityof the developed ANN model Keywords spacer fabrics artificial neural networks transfer properties compression properties porosity thickness and mass
