摘要：
A method of producing a substrate suitable for artificial leathers. The substrate is composed of an entangled nonwoven fabric made of microfine fibers and a binder resin. At least one surface of the substrate is a densified layer which is made of the microfine fibers and which is substantially free from the binder resin. The binder resin is impregnated into a portion of the substrate other than the densified layer. The densified layer prevents the binder resin impregnated into the entangled nonwoven fabric from migrating into the surface of the entangled nonwoven fabric, thereby providing the substrate having the surface substantially free from the binder resin. The peeling strength between the substrate and a grain layer formed on the surface thereof is drastically improved because the surface of the substrate is substantially free from the binder resin.
摘要（中）：
一种适用于人造皮革的基材的制造方法。 基材由由超细纤维和粘合剂树脂制成的缠结无纺布构成。 基材的至少一个表面是由微细纤维制成并且基本上不含粘合剂树脂的致密层。 粘合剂树脂浸渍在除了致密化层之外的基材的一部分中。 致密层防止浸渍到缠结非织造织物中的粘合剂树脂迁移到缠结非织造织物的表面，从而提供具有基本上不含粘合剂树脂的表面的基材。 由于基材的表面基本上不含粘合剂树脂，所以基材和形成在其表面上的颗粒层之间的剥离强度显着提高。
