A carpet is tufted with a two-part primary backing. The upper, or face, backing is a conventional woven or non-woven polypropylene, and the lower, or back, backing is a stronger, open weave fabric. The tufts of yarn are sewn through both parts of the primary backing, which holds the parts together, and causes some of the back stitches to protrude for better coating with adhesive. The resulting carpet may be fully back coated, and may have a secondary backing adhered thereto. The lower backing prevents elongation, stretching and shrinking of the carpet during manufacture and subsequent processing.
Tapis touffeté d'une étoffe support en deux parties. L'étoffe supérieure ou antérieure est un polypropylène tissé ou non, et l'étoffe inférieure ou postérieure est un tissu ajouré plus résistant. Les touffes de fil sont cousues à travers les deux parties de l'étoffe support, ce qui maintient les parties ensemble et fait en sorte que certaines des mailles à l'envers font saillie pour permettre une meilleure adhésion de la colle. Le tapis obtenu peut être entièrement enduit à l'envers, et une sous-couche tissée peut être collée sur lui. L'étoffe inférieure empêche l'allongement, l'étirement et le rétrécissement du tapis pendant sa fabrication et son traitement ultérieur.
