METHOD FOR STABILISING A PILE FABRIC SUCH AS A PILE CARPET PROVIDED WITH AN REINFORCING BACK AND A SHEET CLOTH PRODUCED BY SAID METHOD
A known method for producing pile carpet with tufted pile fibres consists in holding the back side of a support layer with a non-woven and in assembling said support layer with the dorsal fibres of the pile fibres by hydrodynamic needle-punching. Also a known method consisting in placing an intermediate layer between a support layer and the non-woven which consists at least partially of fusing fibres and in connecting said support layer and the non-woven to the back side of a carpet by hydrodynamic needle-punching. The inventive method consists in forming an intermediate layer from a fusing powder or from short cut fusing fibres and in incorporating the support layer in to the carpet back by hydrodynamic needle-punching prior to effectively fixing the pile fibres to the support layer by a fusion process.
