A mathematical model has been  developed relating the compressional behaviour and  parameters, i.e. needling density, depth of  penetration and mass per unit area of jute needle  punched nonwoven. A good correlation has been  observed between compressional parameter (¿) or  recovery parameter (¿) and the properties i.e.  tenacity, elongation-at-break, energy to break, air  permeability and thermal insulation of jute needle  punched nonwoven fabrics. Effect of repeated  compression-recovery cycles, dynamic loading, rate  of deformation, ultimate compressional load,  duration of loading, duration after recovery and  comparison between different testing principles  have been studied and analysed.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838345222\"\u003e\u003ch3\u003ecompressional behaviour of jute cross-laid needle punched nonwoven fabric and comparison with  synthetic fabric and blend\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838345222","offer_id":39498962337885,"sku":"9783838345222","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/172953b0-d954-49a7-b9e0-675bdec82fab.jpg?v=1773122560","url":"https:\/\/shop.autorenwelt.de\/en\/products\/compressional-behaviour-of-needle-punched-nonwoven-fabric-von-surajit-sengupta","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
