Description
本發明係屬於人造皮革技術領域。 The invention belongs to the technical field of artificial leather.
按，人造合成皮革簡單來說，就是在布料上塗敷一層或多層以PU樹脂或PVC做為基布之薄膜，使其表皮具有類似動物皮之質感。一般其反面是牛皮的第二層皮料，所以也稱貼膜牛皮。特別是PU合成皮革除具備了類動物皮質感特性外，更可依據不同強度、耐磨度、耐寒度和色彩、光澤、花紋圖案等要求予以加工製造，進而具備了花色品種繁多、防水性能好、邊幅整齊等特性，是目前世界上代替天然皮革製品最為理想的材料，廣泛應用於鞋類、衣料、箱包袋、球類、傢俱、帆布等領域。 In simple terms, artificial synthetic leather is simply coating one or more layers of film with PU resin or PVC as the base cloth on the cloth, so that its skin has a texture similar to animal skin. Generally, the reverse side is the second layer of leather, so it is also called film leather. In particular, PU synthetic leather, in addition to possessing the characteristics of animal-like cortex, can be processed and manufactured according to different strength, abrasion resistance, cold resistance and color, gloss, pattern and other requirements, and has a wide variety of colors and good waterproof performance. With its neat edges, it is the most ideal material to replace natural leather products in the world. It is widely used in shoes, clothing, bags, balls, furniture, canvas and other fields.
雖然合成皮革有上述諸多優點，卻也非全然沒有缺點：其中像是延展性差就是其本身缺失，再者，皮料層表面之PU或PVC往往需透過熱壓或上膠方式使PU或PVC與皮料層相互貼合，但這樣透過熱壓方式相當耗費電費，而採用上膠方式則易導致PU、或PVC薄膜因黏膠壽命或上膠不均勻等，易導致表層的PU或PVC薄膜剝落，進而造成合成皮革美觀度不佳等問題，更重要的是PU或PVC合成皮革在表面壓紋後形成的壓花紋理與真實皮革有著視覺及觸感層面之極大差距。 Although synthetic leather has many advantages mentioned above, it is not entirely without disadvantages. Among them, poor ductility is its lack. Furthermore, PU or PVC on the surface of the leather layer often requires hot pressing or gluing to make PU or PVC and The leather layers are attached to each other, but this way consumes electricity by hot pressing, and the gluing method is likely to cause the PU or PVC film to peel off due to the life of the adhesive or the uneven gluing. , Which in turn causes problems such as poor aesthetics of synthetic leather, and more importantly, the embossed texture formed on the surface of PU or PVC synthetic leather is significantly different from real leather in terms of visual and tactile aspects.
職是，如何讓人造合成皮革具有真皮皮革之高延展性及高可塑性，以確保合成皮革在加工過程更簡易、快速，且表面形成之壓紋紋理 接近真皮皮革，遂為本發明之主要訴求。 The job is how to make artificial synthetic leather have the high ductility and plasticity of genuine leather, so as to ensure that the synthetic leather has a simpler and faster processing process and the embossed texture formed on the surface. Access to genuine leather is the main requirement of the present invention.
本發明主要係提供一種加工工序簡易、製造快速之合成皮革。 The invention mainly provides a synthetic leather with simple processing steps and fast manufacturing.
本發明另一目的係提供一種耐磨、不易層與層間相互剝離之新穎合成皮革。 Another object of the present invention is to provide a novel synthetic leather which is abrasion-resistant and difficult to peel from each other.

Gives new life to the PVB film inside the windshield that was originally discarded.
再者，合成皮革表面被覆該PVB保護層，則可增加合成皮革之延展性及高可塑性，以利後續表面碾壓形成之壓花紋更接近於動物皮(真皮)表面之紋理，且軟Q的PVB保護層具有止滑特性，讓使用者接觸到該PVB保護層表面壓花紋時，有得接觸動物皮之天然觸感優勢。 Furthermore, the synthetic leather surface is covered with the PVB protective layer, which can increase the ductility and high plasticity of synthetic leather, so that the embossing pattern formed by subsequent surface rolling is closer to the texture of the surface of the animal skin (dermis), and the soft Q The PVB protective layer has a non-slip property, so that when the user touches the surface of the PVB protective layer to be embossed, he has the natural touch advantage of touching animal skin.
更重要的是，PVB保護層，完全不用施以加壓滾壓或上膠方式，即可利用淋膜被覆在該布層表面過程，同時局部滲入該布層內部之發泡基材層表面，以作為該布層與發泡基材層彼此更牢固黏合之接著劑，且長時間使用情況下，亦不會造成該布層與發包基材層相互分離；加上本發明之合成皮革省略了傳統熱壓或上膠程序，讓合成皮革製造工序更簡易，進而獲得更快速製造合成皮革優點。 More importantly, the PVB protective layer can be coated on the surface of the cloth layer without applying pressure and rolling or gluing at the same time, and the surface of the foamed base material layer that penetrates into the cloth layer is partially penetrated at the same time. It is used as an adhesive agent for the cloth layer and the foamed base material layer to be more firmly adhered to each other, and the cloth layer and the outsourcing base material layer will not be separated from each other under long-term use; the synthetic leather of the present invention is omitted Traditional hot-pressing or gluing procedures make the manufacturing process of synthetic leather easier, and thus obtain the advantages of manufacturing synthetic leather faster.
綜上所述可知，本發明之合成皮革，透過本體之布層表面被覆一流體狀之PVB透明保護層，一來增加布層與發泡基材層彼此之牢固連接優點，二來亦可藉其耐磨特性，以確保合成皮革長時間使用下亦不會產生保護層、布層與發泡基材層之間剝離現像，其新穎之設計更獲得了非顯而易見之諸多功效，實已符合發明專利申請要件，爰 依法向鈞局提出發明專利申請，懇請 貴審查委員亦能肯定本發明，並早日賜予專利權，至感德便。 In summary, it can be known that the synthetic leather of the present invention is covered with a fluid PVB transparent protective layer through the surface of the cloth layer of the body, so as to increase the advantages of the strong connection between the cloth layer and the foamed base material layer.
