    • PURPOSE: Polyester nonwoven fabrics are provided to be desirably used as a carpet primary backing substrate by having good properties including tensile strength, elongation, and tear strength even after a tufting process and to simplify a manufacturing process. CONSTITUTION: Polyester nonwoven fabrics are comprised of polyester filament fiber having fineness of 4-10denier. The polyester filament fiber comprises 70-95 weight% of a first polyester polymer having a melting point of 250°C or greater and 5-30 weight% of a second polyester polymer. A method for manufacturing the polyester nonwoven fabrics comprises the following steps: mixing the first polyester polymer and the second polyester polymer; forming polyester filament fibers by spinning and strengthening the polymer mixture; laminating the filament fiber into a web form; and thermally attaching the laminated filament fiber.
    • 目的:即使在簇绒过程之后,通过具有包括拉伸强度,伸长率和撕裂强度在内的良好性能,并且简化制造工艺,聚酯非织造织物被期望地用作地毯主要背衬基材。 构成:聚酯无纺布由细度为4-10旦尼尔的聚酯长丝纤维组成。 聚酯长丝纤维包含70-95重量%的熔点为250℃以上的第一聚酯聚合物和5-30重量%的第二聚酯聚合物。 聚酯无纺布的制造方法包括以下步骤:将第一聚酯聚合物和第二聚酯聚合物混合; 通过纺丝和强化聚合物混合物形成聚酯长丝纤维; 将长丝纤维层压成网状; 并且热粘合层压的长丝纤维。

    • High-elastic non-woven fabric and a manufacturing method thereof are provided to produce non-woven which can be used as a substitute of polyurethane foam or can be used with the polyurethane foam. High-elastic non-woven fabric is manufactured by next steps. The polyester conjugate fiber of 10-70wt%, the polyester conjugate fiber which is processed with oil having silicon of 60% of 10-70wt%, hot sticking binder fiber having a low melting point of 10-70wt%, and polyester or sticking fiber of the polystyrene of 10-70wt% are mixed. A single layer or multilayer of a web is piled up by carding the mixture. The piled web foams a sheet by using a needle having a barb. The sheet is combined with mixture by using a drying furnace and a heating roller.
    • 提供高弹性无纺织物及其制造方法来制造可用作聚氨酯泡沫塑料的替代品的无纺布,或可与聚氨酯泡沫一起使用。 高弹性无纺布由后续步骤制造。 10-70重量%的聚酯复合纤维,具有60%10-70重量%硅的油加工的聚酯复合纤维,具有10-70重量%低熔点的热粘粘合纤维,以及聚酯或粘着纤维 的10-70重量%的聚苯乙烯混合。 通过梳理混合物堆叠单层或多层网。 堆叠的纤维网通过使用具有倒钩的针头来吹动片材。 通过使用干燥炉和加热辊将片材与混合物组合。
