Description
本發明是有關於一種皮革，特別是指一種人工皮革。 The present invention relates to a leather, in particular to an artificial leather.
相較於天然皮革，人工皮革具有質地輕盈、可加工性高，且對生態環境更為友善等優勢而受到消費市場歡迎。一般人工皮革是由多數彼此交織或堆疊的纖維所構成，且依據纖維的結構態樣不同可為海島型纖維、橘瓣型纖維或是皮芯型纖維等多種不同種類的纖維結構。此外，該等纖維依據人工皮革產品特性的需求，可選自聚對苯二甲酸乙二酯(PET)、聚醯胺6(PA6)、聚胺酯(PU)，或是聚乙烯醇(PVA)等具有不同材料特性的高分子材料。 Compared to natural leather, artificial leather is welcomed by the consumer market due to its advantages such as light texture, high processability, and being more eco-friendly. Generally, artificial leather is composed of a plurality of fibers interwoven or stacked with each other, and depending on the fiber structure, it can be a variety of different types of fiber structures such as island-type fiber, segmented fiber, or skin-core fiber. In addition, these fibers can be selected from polymer materials with different material properties such as polyethylene terephthalate (PET), polyamide 6 (PA6), polyurethane (PU), or polyvinyl alcohol (PVA) according to the requirements of the characteristics of artificial leather products.
以具有海島型纖維的人工皮革為例，可利用聚醯胺6或聚胺酯作為島相纖維，由於島相纖維可具有極細的纖維細度，因此可使人工皮革呈現柔軟的皮革觸感。然而，在人工皮革呈現柔軟觸感的同時，卻也容易因為島相纖維的纖維細度極細，導致機械強度不足而發生斷裂，反而不利於產品的加工製程。 Taking artificial leather with island-type fibers as an example, polyamide 6 or polyurethane can be used as island phase fibers. Since the island phase fibers can have extremely fine fiber fineness, the artificial leather can have a soft leather touch. However, while the artificial leather has a soft touch, it is also prone to breakage due to insufficient mechanical strength due to the extremely fine fiber fineness of the island phase fibers, which is not conducive to the processing of the product.
因此，本發明的目的，即在提供一種可同時具有良好的皮革觸感以及足夠的機械強度的人工皮革。 Therefore, the purpose of the present invention is to provide an artificial leather that has both good leather touch and sufficient mechanical strength.
於是，本發明的人工皮革，包含一皮革基材、一水性接著層，及一樹脂面層。 Therefore, the artificial leather of the present invention includes a leather substrate, a water-based adhesive layer, and a resin surface layer.
該皮革基材包括一層長纖維紡黏層，以及二層分別形成於該長纖維紡黏層相對兩側的短纖維梳棉層。 The leather substrate includes a long-fiber spunbond layer and two short-fiber combed cotton layers formed on opposite sides of the long-fiber spunbond layer.
該水性接著層形成於該皮革基材的其中一表面。 The water-based adhesive layer is formed on one surface of the leather substrate.
該樹脂面層形成於該水性接著層反向於該皮革基材的一面，經由該水性接著層與該皮革基材貼合。 The resin surface layer is formed on the side of the water-based adhesive layer opposite to the leather substrate, and is bonded to the leather substrate via the water-based adhesive layer.
其中，該長纖維紡黏層及該等短纖維梳棉層分別具有由聚對苯二甲酸乙二酯(PET)，及聚醯胺6(PA6)構成的橘瓣型分割纖維。 The long fiber spunbond layer and the short fiber carded cotton layers respectively have segmented fibers made of polyethylene terephthalate (PET) and polyamide 6 (PA6).
本發明的功效在於：利用將該等短纖維梳棉層設置於該長纖維紡黏層相對兩側以構成該皮革基材，且該長纖維紡黏層及該等短纖維梳棉層具有由聚對苯二甲酸乙二酯(PET)，及聚醯胺6(PA6)所構成的橘瓣型分割型纖維，可使該皮革基材同時具有良好的柔軟度與機械強度，並呈現良好的皮革觸感。 The effect of the present invention is that the short fiber carded cotton layers are arranged on opposite sides of the long fiber spunbond layer to form the leather substrate, and the long fiber spunbond layer and the short fiber carded cotton layers have segmented fibers composed of polyethylene terephthalate (PET) and polyamide 6 (PA6), so that the leather substrate has good softness and mechanical strength at the same time, and presents a good leather touch.

在本發明被詳細描述前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。有關本發明之相關技術內容、特點與功效，在以下配合參考圖式之實施例的詳細說明中，將可清楚的呈現。此外，要說明的是，本發明圖式僅為表示元件間的結構及/或位置相對關係，與各元件的實際尺寸並不相關。 Before the present invention is described in detail, it should be noted that similar components are represented by the same number in the following description. The relevant technical content, features and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the drawings. In addition, it should be noted that the drawings of the present invention only represent the relative relationship between the structure and/or position of the components, and are not related to the actual size of each component.
參閱圖1，本發明人工皮革200的一實施例，包含一皮革基材2、一水性接著層3，及一樹脂面層4。 Referring to FIG. 1 , an embodiment of the artificial leather 200 of the present invention comprises a leather substrate 2, a water-based adhesive layer 3, and a resin surface layer 4.
該皮革基材2包括一層長纖維紡黏層21，以及二層分別形成於該長纖維紡黏層21相對兩側的短纖維梳棉層22，且該皮革基材2的縱向(Machine direction，MD)抗拉強度不小於8Kg/cm，橫向(Cross direction，CD)抗拉強度不小於4Kg/cm。 The leather substrate 2 includes a long fiber spunbond layer 21 and two short fiber combed cotton layers 22 formed on opposite sides of the long fiber spunbond layer 21, and the longitudinal tensile strength (machine direction, MD) of the leather substrate 2 is not less than 8Kg/cm, and the cross direction (cross direction, CD) tensile strength is not less than 4Kg/cm.
該水性接著層3形成於該皮革基材2的其中一表面。在本實施例中，該水性接著層3選自陰離子水性聚氨酯樹脂，是經由塗佈、烘乾等製程形成於該皮革基材2表面。 The water-based bonding layer 3 is formed on one surface of the leather substrate 2. In this embodiment, the water-based bonding layer 3 is selected from anionic water-based polyurethane resin and is formed on the surface of the leather substrate 2 through processes such as coating and drying.
該樹脂面層4形成於該水性接著層3反向於該皮革基材2的一面，經由該水性接著層3與該皮革基材2緊密地貼合。該樹脂面層4選自水溶性聚氨酯樹脂，是經由塗佈、烘乾等製程形成於該水性接著層3上。 The resin surface layer 4 is formed on the side of the water-based adhesive layer 3 opposite to the leather substrate 2, and is closely attached to the leather substrate 2 through the water-based adhesive layer 3. The resin surface layer 4 is selected from water-soluble polyurethane resin and is formed on the water-based adhesive layer 3 through processes such as coating and drying.
由於該水性接著層3以及該樹脂面層4皆選自水性材料，而於製程中無需使用大量的有機溶劑，不易產生污染物，而對環境友善。 Since the water-based adhesive layer 3 and the resin surface layer 4 are both made of water-based materials, a large amount of organic solvents do not need to be used in the manufacturing process, pollutants are not easily generated, and the process is environmentally friendly.
具體地說，前述該長纖維紡黏層21及該等短纖維梳棉層22為具有由聚對苯二甲酸乙二酯(PET)，及聚醯胺6(PA6)構成的橘瓣型分割(segment pie)纖維(如圖2、圖3所示)。由於該橘瓣型分割纖維是由多數成薄平狀且密集排列的纖維瓣所構成而具有良好的覆蓋性，可使該皮革基材2兼具防水性與透氣性。 Specifically, the aforementioned long fiber spunbond layer 21 and the short fiber carded cotton layers 22 are segment pie fibers composed of polyethylene terephthalate (PET) and polyamide 6 (PA6) (as shown in Figures 2 and 3). Since the segment pie fibers are composed of a plurality of thin, flat and densely arranged fiber segments, they have good coverage, and can make the leather substrate 2 both waterproof and breathable.
再參閱圖2，圖2為該長纖維紡黏層21的其中一條長纖維211的剖視結構圖。該長纖維紡黏層21是由多數長纖維211構成，每一條長纖維211為橘瓣型分割纖維，具有多數聚對苯二甲酸乙二酯(PET)構成的PET纖維瓣211A，以及多數聚醯胺6(PA6)構成的PA6纖維瓣211B，且該等PET纖維瓣211A和該等PA6纖維瓣211B 彼此交替間隔排列。其中，該長纖維紡黏層21的聚醯胺6的體積佔比介於50%至60%，每一條長纖維211的纖維瓣(即該等PET纖維瓣211A與該等PA6纖維瓣211B)的瓣數總和介於24至128，且纖維細度介於0.05D至10D(Denier)。較佳地，該長纖維紡黏層21的聚醯胺6的體積佔比大於聚對苯二甲酸乙二酯，而能提升本身的韌性，呈現皮革特有的柔軟觸感。 Referring to FIG. 2, FIG. 2 is a cross-sectional structural diagram of one of the long fibers 211 of the long fiber spun adhesive layer 21. The long fiber spun adhesive layer 21 is composed of a plurality of long fibers 211, each of which is a segmented fiber of the orange segment type, having a plurality of polyethylene terephthalate (PET) fiber segments 211A composed of PET, and a plurality of polyamide 6 (PA6) fiber segments 211B composed of PA6, and the PET fiber segments 211A and the PA6 fiber segments 211B are arranged alternately and spaced apart from each other. The volume ratio of polyamide 6 in the long fiber spun adhesive layer 21 is between 50% and 60%, the total number of fiber petals of each long fiber 211 (i.e., the PET fiber petals 211A and the PA6 fiber petals 211B) is between 24 and 128, and the fiber fineness is between 0.05D and 10D (Denier). Preferably, the volume ratio of polyamide 6 in the long fiber spun adhesive layer 21 is greater than that of polyethylene terephthalate, which can enhance its own toughness and present the soft touch unique to leather.
在一些實施例中，該長纖維紡黏層21依據製程方式不同，可為紡黏不織布、熔噴不織布、針軋不織布，或是靜電紡絲不織布。 In some embodiments, the long fiber spunbond layer 21 can be a spunbond non-woven fabric, a meltblown non-woven fabric, a needle-rolled non-woven fabric, or an electrostatically spun non-woven fabric, depending on the manufacturing process.
再配合參閱圖3，圖3為該等短纖維梳棉層22的其中一條短纖維221的剖視結構圖。該等短纖維梳棉層22是由多數短纖維221所構成，並經由水軋法固結形成於該長纖維紡黏層21的相對兩側。該等短纖維梳棉層22的每一條短纖維221也是由多數聚對苯二甲酸乙二酯構成的PET纖維瓣221A，及多數聚醯胺6構成的PA6纖維瓣221B交替間隔排列所構成的橘瓣型分割纖維。其中，該等短纖維梳棉層22的聚醯胺6的體積佔比介於40%至50%，每一條短纖維221的纖維瓣(即該等PET纖維瓣221A與該等PA6纖維瓣221B)的瓣數總和介於16至128，纖維細度介於0.5D至30D。較佳地，該等短纖維梳棉層的聚對苯二甲酸乙二的體積佔比大於酯聚醯胺6，而可增加該等短纖維梳棉層22本身的拉伸強度。 Referring to FIG. 3, FIG. 3 is a cross-sectional structural diagram of one of the short fibers 221 of the short fiber combed cotton layer 22. The short fiber combed cotton layer 22 is composed of a plurality of short fibers 221, and is formed on opposite sides of the long fiber spunbond layer 21 by water rolling consolidation. Each short fiber 221 of the short fiber combed cotton layer 22 is also a segmented fiber composed of a plurality of PET fiber petals 221A composed of polyethylene terephthalate and a plurality of PA6 fiber petals 221B composed of polyamide 6 arranged alternately and spaced apart. The volume ratio of polyamide 6 in the short fiber carded cotton layer 22 is between 40% and 50%, the total number of fiber petals of each short fiber 221 (i.e., the PET fiber petals 221A and the PA6 fiber petals 221B) is between 16 and 128, and the fiber fineness is between 0.5D and 30D. Preferably, the volume ratio of polyethylene terephthalate in the short fiber carded cotton layer is greater than that of polyamide 6, which can increase the tensile strength of the short fiber carded cotton layer 22 itself.
在一些實施例中，該等短纖維梳棉層22依據製程方式不同，可為熱風不織布、熱壓不織布，或是針軋不織布。 In some embodiments, the short fiber carded cotton layer 22 can be hot air non-woven fabric, heat pressed non-woven fabric, or needle rolled non-woven fabric according to different manufacturing processes.
較佳地，該等短纖維梳棉層22的聚對苯二甲酸乙二的體積佔比大於該長纖維紡黏層21的聚對苯二甲酸乙二的體積佔比，而具有較佳的機械強度。 Preferably, the volume ratio of polyethylene terephthalate in the short-fiber carded cotton layer 22 is greater than the volume ratio of polyethylene terephthalate in the long-fiber spunbond layer 21, and has better mechanical strength.
較佳地，任一層短纖維梳棉層22中的該等短纖維221的纖維瓣的平均瓣數總和少於該長纖維紡黏層21中的該等長纖維211的纖維瓣的平均瓣數總和，而可具有較佳的機械強度，以對夾設其中的內裡(即該長纖維紡黏層21)提供保護作用，且因該長纖維紡黏層21的纖維瓣的瓣數較多，因此可較為蓬鬆。 Preferably, the average sum of the fiber petals of the short fibers 221 in any layer of the short fiber carded cotton layer 22 is less than the average sum of the fiber petals of the long fibers 211 in the long fiber spunbond layer 21, and can have better mechanical strength to provide protection for the inner lining (i.e. the long fiber spunbond layer 21) sandwiched therein, and because the fiber petals of the long fiber spunbond layer 21 have more petals, they can be more fluffy.
在一些實施例中，該皮革基材2的構成材料(聚對苯二甲酸乙二酯及聚醯胺6)是選自回收材料，而可更具有環境友善特性。 In some embodiments, the constituent materials of the leather substrate 2 (polyethylene terephthalate and polyamide 6) are selected from recycled materials, which can be more environmentally friendly.
綜上所述，本發明人工皮革200利用將聚醯胺6的體積佔比較高且纖維瓣的瓣數較多的該長纖維紡黏層21設置於該皮革基材2的內裡，使該皮革基材2具有優秀的韌性並呈現柔軟的觸感，將聚對苯二甲酸乙二酯的體積佔比較高且纖維瓣的瓣數較少的該等短纖維梳棉層22設置於該長纖維紡黏層21的外側，以提升該皮革基材2的拉伸強度，使本發明該人工皮革200呈現柔軟的皮革觸感，同時保有足夠的機械強度，此外，該人工皮革200選用該水性接著層3和由陰離子水性聚氨酯樹脂構成的該樹脂面層4，可減少在 製程中大量使用有機溶劑，而對環境友善，故確實可達成本發明的目的。 In summary, the artificial leather 200 of the present invention uses the long fiber spun adhesive layer 21 with a relatively high volume of polyamide 6 and a large number of fiber petals to be arranged inside the leather substrate 2, so that the leather substrate 2 has excellent toughness and presents a soft touch, and the short fiber combed cotton layer 22 with a relatively high volume of polyethylene terephthalate and a small number of fiber petals is arranged on the long fiber spun adhesive layer 21. The outer side of the leather substrate 2 is provided to enhance the tensile strength of the leather substrate 2, so that the artificial leather 200 of the present invention has a soft leather touch while maintaining sufficient mechanical strength. In addition, the artificial leather 200 uses the water-based adhesive layer 3 and the resin surface layer 4 composed of anionic water-based polyurethane resin, which can reduce the large amount of organic solvents used in the process and is environmentally friendly, so the purpose of the present invention can be achieved.
