In particular,foamstabilizers have consciously been added in order to prevent thefoam from breaking down after being applied.  Thus,by applicationof foamed pastes in a suitable thickness,a considerable thermalinsulation,noise damping,slip resistance and an increase in theoverall thickness of the entire carpet are achieved.  Nevertheless,the connection between the foam layer and the pile and backing fabricis still unsatisfactory in this case.  This is particularly dueto the fact that the gel temperature is in effect in the zone ofcontact between the fibers of the backing and the foam only for arelatively short time since the thermal conduction conditions inthe case of heating,on the one hand,through the foam layer andon the other hand,through the pile floor covering itself are veryunfavorable.  \nThe invention is thus based on the problem of suggesting asimple process that guarantees a flawless bond between the foamand the pile or woven fabric.  The previously known advantages,such as thermal insulation,sound damping,slip-resistance andincrease in the overall thickness of the entire coated floorcovering material should be retained.  \nThis is achieved according to the invention by first waitingfor the beginning of liquefaction of the foamed thermoplastic  \nbefore pressing the liquefied foam between the fibers of the backingand pile threads and only then undertaking the solidification byheating.  In this way an anchoring of the foam layer in the inter-stices between the backing and pile threads is achieved and aparticularly advantageous sort of bond is achieved in which thereliquefied and later gelled foam envelops the individual fibers.A prerequisite for such envelopment is first the penetration ofthe coating into the interstices between the threads.  This isprecisely what the initial liquefaction makes possible,since thecoating is applied to the upward-facing back side of the floorcovering and the liquefied material migrates downward.  This typeof anchoring simultaneously results in fixing the pile threads.  \nIn a further refinement of the invention,the thermoplasticpaste,which,in particular,can be a PVC mixed with plasticizer,is mechanically foamed in such a way that its pore size is smallerthan t","cbCaianzNRq1wnsh","https://ap.wps.com/l/cbCaianzNRq1wnsh","pdf",1108993,28,"English","# Method for Production of a Pile Floor Covering\n## Background and problem\n## Proposed solution and process steps\n## Foam structure refinement\n## Optional chilling during gelling","[{\"question\":\"What is the core idea of the proposed method for producing the pile floor covering?\",\"answer\":\"The method first waits for the beginning of liquefaction of the mechanically foamed thermoplastic, then presses the liquefied foam between the backing and pile fibers before heating to solidify at the gel point.\"},{\"question\":\"How does the invention improve the bond between the foam layer and the pile/backing fabric?\",\"answer\":\"Initial liquefaction lets the coating penetrate the interstices as it migrates downward, anchoring the foam layer and allowing later gelled foam to envelop individual fibers while fixing the pile threads.\"},{\"question\":\"What additional refinements are described for the thermoplastic foam?\",\"answer\":\"The thermoplastic paste can be foamed so the pore size is smaller than the fiber diameter, helping retain fibers even if some gas-filled pores penetrate.
