Abstract: The invention concerns a thermomoldable carpet having a 100 % recyclable insulator made of a single polymer laminated onto a secondary substrate by thermofusion based on infrared units. Recycled low-denier-per-filament fibers made of the same polymer or resin as that of the surface or primary base of the carpet are used as means for mechanical backing. Said fibers must not necessarily have a different molecular weight or a different fusion point. The fibers form a bonded-pile or fabric and are applied by simple superimposition and tied when the threads are inserted during the tufting process of the carpet. The fibers may also form a non-woven. Secondary lamina layers and the same polymer or resin used for the other elements already applied to the carpet are laminated onto the non-woven, one of said layers being a foam insulator. All components have one common denominator, namely the thermoplastic resin, which makes them 100 % recyclable. No other method such as precipitation or the like is needed for the selection of the polymers. In order to manufacture a recyclable thermomoldable carpet, the front and rear sides of the carpet are protected during the manufacturing process by performing wetting and by applying a cooling process using sprinklers and tools with water re-circulation and chambers in which cold air is applied.

Abstract translation: 本发明涉及一种热塑性地毯，其具有通过基于红外单元的热熔融层压到二次基底上的单一聚合物制成的100％可循环绝缘体。 用与地毯的表面或主底层相同的聚合物或树脂制成的回收的低旦/长丝纤维用作机械背衬的手段。 所述纤维不一定具有不同的分子量或不同的融合点。 纤维形成粘合桩或织物，并且当在地毯的簇绒过程中插入螺纹时通过简单的叠加施加并捆扎。 纤维也可以形成无纺布。 用于已经施加到地毯上的其它元件的相同聚合物或树脂被层压到无纺布上，所述层之一是泡沫绝缘体。 所有组分都有一个共同特征，即热塑性树脂，使其100％可回收利用。 聚合物的选择不需要析出等其他方法。 为了制造可回收的热塑性地毯，在制造过程中通过进行润湿和使用具有再循环的喷洒器和工具的冷却过程以及施加冷空气的室来保护地毯的前侧和后侧。
