Knitted artefact with heat shrinking yarns

Abstract

An assembly is described for chairs, armchairs, sofas and the like, comprising a knitted artefact ( 1 ) and sliders ( 12 ). The artefact ( 1 ) comprises a multilayer and two ends ( 11 ) of tubular shape for fixing the multilayer, wherein the multilayer comprises a knitted fabric front layer ( 2 ) and a knitted fabric rear layer ( 3 ) fixed to sliders ( 12 ) of the artefact ( 1 ) at said two ends ( 11 ). The artefact ( 1 ) further comprises heat-shrinking yarns ( 5 ) associated with the multilayer, wherein the heat-shrinking yarns ( 5 ) are fixed with a series of connection points ( 7 ) spaced apart to the sliders ( 12 ) so as to develop in weft between the two ends ( 11 ) of the artefact ( 1 ).

1 . Assembly for chairs, armchairs, sofas and the like, comprising a knitted artefact and sliders, wherein the artefact comprises a multilayer and two ends of tubular shape for fixing the multilayer,
 wherein the multilayer comprises a knitted fabric front layer and a knitted fabric rear layer fixed to the sliders at the two ends,   wherein the artefact also comprises heat-shrinking yarns fixed to the multilayer, wherein the heat-shrinking yarns are fixed with a series of connection points spaced apart to the sliders so as to develop in weft between the two ends of the artefact,   wherein   the heat-shrinking yarns are fixed to the knitted fabric rear layer at an external part of the knitted fabric rear layer, with a further series of the connection points spaced apart,   the knitted fabric front layer comprises a plurality of plastic elements spaced apart,   the plastic elements penetrate the knitted fabric.   
     
     
         2 . The assembly according to  claim 1 , wherein a connection point is provided for every five or more beatings up of the knitted fabric rear layer. 
     
     
         3 . The assembly according to  claim 1 , wherein the number of the heat-shrinking yarns is less than 20% of total yarns of the artifact. 
     
     
         4 . The assembly according to  claim 2 , wherein the number of the heat-shrinking yarns is between 3% and 8% of total yarns of the artefact. 
     
     
         5 . The assembly according to  claim 1 , wherein the multilayer comprises a padding between the knitted fabric front layer and the knitted fabric rear layer. 
     
     
         6 . The assembly according to  claim 1 , wherein the artefact has a tubular shape between the two ends.
