ABSTRACT Spacer fabrics are combination of two separated kinitted fabrics which are jointedtogether with a layer of monofilaments The middle layer in these fabrics causes toestablish a unique characteristic In most of cases these type of fabrics are used as pressuredistributor or diminishing for automobile industry medical textiles technical and industrialtextiles geotextile and athletic garments In most of applications this textiles are exposedto fairly high lateral compression and their reaction to the compression forces are soimportant With due attention to the magnitude to type of pressure behavior of different fabrics inapplication at various field in this research the reaction of spacer fabrics to appliedpressure forces have been investigated The most important factor in pressure behavioureof middle monofilaments reaction In order to simulate the lateral compression behavioureof spacer fabrics six different type of samples were prepared samples contain twocompletely solid sheets linked together by monofilaments with different physicalparameters Then two flat attachable sheets made for strength tester as two pressureclampes Using this clampes the pressure test was carried out on the Zwick test Twosamples of actual spacer fabric with the same conditions were also tested The resultsshowed that the trend of deformation force in the samples and actual spacer fabrics areidentical Also the results are revealed that some difference parameters such as finenessand monofilaments position affecting the pressure behavioure of this fabrics withincreasing the monofilament fineness compression modulus is decreased To explaining of the behavioure of force deformation of spacer fabrics twomechanical and mathematical modeling are accomplished In the first model the theory oflarge deformation in the post buckling was used The results showed that the theoreticalvalues obtained from the modeling are not compatible with the experimentalresults However the fitted curves obtained from experimentals showe a good agreementwith the second model based on Van Wyk s theory
