Description
本創作係有關於一種多層式彈性透氣材料結構,尤其是利用具緯向延伸率的至少一聚乳酸彈性布貼合至少一彈性薄膜,達到高透氣性且在緯向具強力回彈性的特點。This creation is about a multilayer elastic breathable material structure, especially using at least one polylactic acid elastic cloth with weft elongation to paste at least one elastic film to achieve high air permeability and strong resilience in the weft direction.
一般的衛生用品在考量到衛生及使用安全時,通常會採用一次性或可棄式的使用方式,避免遭受病菌或有害物質的污染,比如口罩、免洗衣褲、嬰幼兒尿布或成人尿布。這類產品因為會與皮膚接觸一段時間,所以對透氣性的要求較為嚴格,防止因悶熱或悶濕所導致的不適感或皮膚過敏、發癢,甚至出疹。When considering the hygiene and safety of general sanitary products, they are usually used in a disposable or disposable manner to avoid contamination by germs or harmful substances, such as masks, disposable trousers, baby diapers or adult diapers. Because these products will be in contact with the skin for a period of time, the gas permeability requirements are more stringent to prevent discomfort or skin irritation, itching, and even rash caused by stuffiness or moisture.
由於來自塑化材料的不織布具有容易製造、加工、抗化性佳、耐用及成本低廉的優點,已被廣泛應用於許多衛生用品。但是不織布的延伸性較差,對於需要穿戴的應用,比如尿布,會造成使用上的不便,因此,業者已開發出能改善延伸性的不織布,可稱作彈性不織布。Since the non-woven fabrics from plasticized materials have the advantages of being easy to manufacture, process, have good chemical resistance, durability and low cost, they have been widely used in many sanitary products. However, the non-woven fabric has poor extensibility. For applications that require wear, such as diapers, it causes inconvenience in use. Therefore, the industry has developed a non-woven fabric that can improve the extensibility, which can be called elastic non-woven fabric.
在習用技術中,一般是對不織布施以單向拉力,再破壞纖維結構,並在釋放原有施力之後,自然回復收縮而形成單向彈性延伸的彈性不織布。In conventional technology, a unidirectional tensile force is generally applied to the non-woven fabric, and then the fiber structure is destroyed. After the original force is released, the non-woven fabric naturally recovers and contracts to form a unidirectional elastically stretched elastic non-woven fabric.
此外,業者還進一步推出多層的複合結構以加強彈性回復力功效,通常是在上、下層的彈性不織布中包夾彈性薄膜,藉以提供類似鬆緊帶的功能,方便穿戴。然而,習用技術的缺點在於彈性薄膜本身的透氣性差,會導致整體的透氣性大幅降低,不利於皮膚的接觸感受。In addition, the industry has also introduced multi-layer composite structures to enhance the elastic restoring force. Usually, the elastic film is sandwiched between the upper and lower layers of elastic non-woven fabrics to provide elastic band-like functions for easy wearing. However, the conventional technology has the disadvantage that the elastic film itself has poor air permeability, which will cause the overall air permeability to be greatly reduced, which is not conducive to skin contact.
因此,非常需要一種創新的多層式彈性透氣材料結構,利用具緯向延伸率的聚乳酸彈性布貼合彈性薄膜,達到高透氣性,同具有在緯向上的強力回彈性,適合製作貼身衣物或尿布,藉以解決上述習用技術的所有問題。Therefore, there is a great need for an innovative multi-layer elastic breathable material structure. Polylactic acid elastic cloth with weft elongation is used to adhere the elastic film to achieve high breathability. It also has strong resilience in the weft direction and is suitable for making intimate clothing or Diapers to solve all the problems of the conventional techniques described above.
本創作之主要目的在於提供一種多層式彈性透氣材料結構,包括彈性布及彈性薄膜,其中彈性布是由聚乳酸構成,具有貫穿的多個透氣孔,且緯向上具有150%至400%的延伸率,而彈性薄膜是由熱塑性彈性體材料構成,比如TPE-E/S/A、TPO、TPV或TPU,並具有貫穿的多個透氣孔,且彈性薄膜的上表面是完全貼合或部分貼合到彈性布的下表面,尤其,彈性薄膜的透氣性為每平方公分17~25 cc/sec,且多層式彈性透氣材料結構的透氣性是每平方公分7~10 cc/sec。此外,彈性薄膜的透氣孔是對齊或不對齊彈性布的透氣孔。The main purpose of this creation is to provide a multi-layer elastic breathable material structure, including an elastic cloth and an elastic film, wherein the elastic cloth is made of polylactic acid, has a plurality of through holes, and has an extension of 150% to 400% in the weft direction. The elastic film is made of thermoplastic elastomer material, such as TPE-E / S / A, TPO, TPV or TPU, and has a plurality of through holes, and the upper surface of the elastic film is fully or partially adhered. Fitted to the lower surface of the elastic cloth, in particular, the air permeability of the elastic film is 17 ~ 25 cc / sec per square centimeter, and the air permeability of the multilayer elastic breathable material structure is 7 ~ 10 cc / sec per square centimeter. In addition, the ventilation holes of the elastic film are the ventilation holes of the aligned or misaligned elastic cloth.
由於彈性布只在緯向具有可拉伸的回彈性,在經向是不具可拉伸的回彈性,再加上彈性薄膜可直接或間接貼合彈性布,因而額外賦予彈性布更大的緯向回復性,所以整體的多層式彈性透氣材料結構在緯向具有很強的彈性拉伸回復力。另外,加上彈性布、彈性薄膜具有適當的透氣性的優點,很適合應用於貼身衣物或尿布的領域,改善舒適感,避免悶熱、潮濕而長疹子或發癢。Because the elastic cloth has stretchable resilience only in the weft direction, there is no stretchable resilience in the warp direction, plus the elastic film can directly or indirectly fit the elastic cloth, so the elastic cloth is given a larger weft. Due to its reversibility, the overall multi-layer elastic breathable material structure has a strong elastic recovery force in the weft direction. In addition, the addition of elastic cloth and elastic film has the advantage of proper breathability, which is very suitable for use in the field of intimate clothing or diapers, improving comfort, and avoiding hot, humid and rash or itching.
以下配合圖示及元件符號對本創作之實施方式做更詳細的說明,俾使熟習該項技藝者在研讀本說明書後能據以實施。The following is a more detailed description of the implementation of this creation with illustrations and component symbols, so that those skilled in the art can implement it after studying this manual.
參考第一圖,本創作第一實施例多層式彈性透氣材料結構的示意圖。如第一圖所示,本創作第一實施例的多層式彈性透氣材料結構包括彈性布10及彈性薄膜20,且彈性薄膜20的上表面是完全貼合或部分貼合到彈性布10的下表面,形成雙層堆疊結構。上述的部分貼合可有多種的實施方式,用以達成矩陣排列的局部性點狀貼合、格狀貼合、條狀貼合,等等,而第一圖是顯示部分貼合的示範性實例。Referring to the first figure, a schematic diagram of a multilayer elastic breathable material structure according to the first embodiment of the present invention is created. As shown in the first figure, the multi-layered elastic breathable material structure of the first embodiment of the present invention includes an elastic cloth 10 and an elastic film 20, and the upper surface of the elastic film 20 is fully or partially attached to the bottom of the elastic cloth 10 On the surface, a double-layer stack structure is formed. There can be various implementations of the partial bonding described above to achieve local point bonding, grid bonding, strip bonding, etc. of the matrix arrangement, and the first figure shows an exemplary partial bonding. Instance.
具體而言,彈性布10是由聚乳酸(poly lactic acid,PLA)構成,可為不織布,並具有多個透氣孔12,是貫穿彈性布10的上表面及下表面,尤其是,彈性布10在緯向上具有一延伸率,其中延伸率係較佳的為150%至400%之間。Specifically, the elastic cloth 10 is made of poly lactic acid (PLA), may be a non-woven cloth, and has a plurality of ventilation holes 12. The elastic cloth 10 penetrates the upper surface and the lower surface of the elastic cloth 10. In particular, the elastic cloth 10 It has an elongation in the weft direction, and the elongation is preferably between 150% and 400%.
上述的彈性薄膜20是由熱塑性彈性體材料構成,比如熱塑性聚酯(Thermoplastic polyester,TPE-E)、熱塑性聚苯乙烯嵌段 (Thermoplastic polystyrenic block,TPE-S)、熱塑性聚胺 (Thermoplastic polyamide,TPE-A)、熱塑性聚烯烴(Thermoplastic polyolefin,TPO)、熱塑性硫化橡膠(Thermoplastic vulcanizate,TPV)或熱塑性聚氨基甲酸酯(Thermoplastic polyurethane,TPU),而且具有多個透氣孔22,是貫穿彈性薄膜20的上表面及下表面。特別的是,彈性薄膜20的透氣性為每平方公分17~25 cc/sec。The aforementioned elastic film 20 is made of a thermoplastic elastomer material, such as a thermoplastic polyester (TPE-E), a thermoplastic polystyrenic block (TPE-S), and a thermoplastic polyamide (TPE -A), thermoplastic polyolefin (Thermoplastic polyolefin, TPO), thermoplastic vulcanizate (TPV) or thermoplastic polyurethane (Thermoplastic polyurethane, TPU), and has a plurality of ventilation holes 22, which penetrates the elastic film 20 Upper and lower surfaces. In particular, the air permeability of the elastic film 20 is 17 to 25 cc / sec.
此外,彈性薄膜20的該等透氣孔22可對齊或不對齊彈性布10的該等透氣孔12,而且整個多層式彈性透氣材料結構的透氣性是特別設計成每平方公分7~10 cc/sec。In addition, the air holes 22 of the elastic film 20 can be aligned or misaligned with the air holes 12 of the elastic cloth 10, and the air permeability of the entire multi-layer elastic air-permeable material structure is specially designed to be 7-10 cc / sec per square centimeter. .
再者,彈性薄膜20的上表面及彈性布10的下表面可藉超音波融接或熱壓融接而直接貼合成雙層結構,或者,也可在彈性薄膜20及彈性布10之間利用塗佈額外的黏合膠料(圖中未顯示)而貼合,其中黏合膠料可為苯乙烯/異戊二烯/苯乙烯(SIS)或苯乙烯/乙-丁烯/苯乙烯(SEBS)。另一方式是直接將黏合膠料擠出到彈性布10而形成彈性薄膜20,可同時達到貼合的目的。Furthermore, the upper surface of the elastic film 20 and the lower surface of the elastic cloth 10 may be directly laminated to a double-layer structure by ultrasonic fusion or thermal compression welding, or may be used between the elastic film 20 and the elastic cloth 10 Apply additional adhesive (not shown) for bonding, where the adhesive can be styrene / isoprene / styrene (SIS) or styrene / ethyl-butene / styrene (SEBS) . Another way is to directly extrude the adhesive material to the elastic cloth 10 to form the elastic film 20, which can achieve the purpose of lamination at the same time.
更加具體而言,在彈性薄膜20是部分貼合到彈性布10時,並經緯向拉伸後,會因彈性布10的永久變形率大於彈性薄膜20,造成回縮後未經超音波熔接的部分,會形成波浪狀表面隆起(如圖中所示),可大幅增加表面積,擴大應用領域,同時也可提升棉質手感與因布面蓬鬆產生的厚實感。More specifically, when the elastic film 20 is partially adhered to the elastic cloth 10 and stretched in the warp and weft directions, the permanent deformation rate of the elastic cloth 10 is greater than that of the elastic film 20, resulting in no ultrasonic fusion after retraction. In part, it will form a wavy surface bulge (as shown in the figure), which can greatly increase the surface area and expand the application area. At the same time, it can also improve the feel of cotton and the thick feeling caused by the fluffy cloth surface.
接著參考第二圖,本創作第二實施例多層式彈性透氣材料結構的示意圖,係類似於第一實施例,其主要差異在於額外包括另一彈性布30,也是由聚乳酸構成,並具有貫穿的多個透氣孔32,且另一彈性布30的上表面是完全貼合或部分貼合到彈性薄膜20的下表面。再者,另一彈性布30的透氣孔32是對齊或不對齊彈性薄膜20的透氣孔22,亦即,是在第一實施例的彈性薄膜20底下。Next, referring to the second figure, the schematic diagram of the structure of the multilayer elastic breathable material in the second embodiment of this creation is similar to the first embodiment. The main difference is that it additionally includes another elastic cloth 30, which is also made of polylactic acid and has a penetration The upper surface of the other elastic cloth 30 is completely or partially adhered to the lower surface of the elastic film 20. Furthermore, the ventilation holes 32 of the other elastic cloth 30 are the ventilation holes 22 of the elastic film 20 aligned or misaligned, that is, under the elastic film 20 of the first embodiment.
第三圖是本創作第三實施例多層式彈性透氣材料結構的示意圖,是包含彈性布10、彈性薄膜20、另一彈性布30以及另一彈性薄膜40的四層結構,其中另一彈性薄膜40也是由熱塑性彈性體材料構成,而且彈性布10、彈性薄膜20、另一彈性薄膜40以及另一彈性布30是依序由上而下堆疊而成。此外,各層之間未完全貼合。同樣的,另一彈性薄膜40具有貫穿的多個透氣孔42,可對齊或對齊於該等透氣孔22、透氣孔32,而要注意的是,圖中是顯示透氣孔12、透氣孔22、透氣孔42、透氣孔32為相互對齊的實例。The third figure is a schematic view of the structure of a multilayer elastic breathable material according to the third embodiment of the present invention. It is a four-layer structure including an elastic cloth 10, an elastic film 20, another elastic cloth 30, and another elastic film 40. 40 is also made of a thermoplastic elastomer material, and the elastic cloth 10, the elastic film 20, the other elastic film 40, and the other elastic cloth 30 are sequentially stacked from top to bottom. In addition, the layers were not fully bonded. Similarly, another elastic film 40 has a plurality of through holes 42 which can be aligned or aligned with the through holes 22 and 32, and it should be noted that the figure shows the through holes 12, the through holes 22, The ventilation holes 42 and the ventilation holes 32 are examples aligned with each other.
上述的透氣孔12、透氣孔22、透氣孔32、透氣孔42可利用針扎、針刺方式(Needle Punching)而達成,比如經過針輪,因針輪上的針頭具高溫,可達到刺穿目的而形成圓狀環孔的透氣孔,並可藉改變孔徑或排列密度而調整出最佳的透氣率。此外,也可利用熱壓打孔實現,先將整個多層式彈性透氣材料結構經過一組具公母紋路之上下壓輪的滾壓,在透過高溫以達到穿孔效果,之後,經過一組光面壓輪而將表面壓平。或者,在彈性薄膜在未與彈性布貼合之前,先加工成具有孔洞的網狀膜,之後再貼合到彈性布,同樣可改善透氣性。The above-mentioned ventilation holes 12, ventilation holes 22, ventilation holes 32, and ventilation holes 42 can be achieved by using needle piercing and needling (Needle Punching). For example, passing through the needle wheel, because the needle on the needle wheel has high temperature, it can be pierced. The purpose is to form a vent hole with a circular ring hole, and the optimal air permeability can be adjusted by changing the hole diameter or the arrangement density. In addition, it can also be achieved by hot pressing. First, the entire multi-layer elastic breathable material structure is rolled through a set of upper and lower rollers with male and female lines, and the high temperature is used to achieve the perforation effect. After that, it passes through a set of smooth surfaces. Press the wheel to flatten the surface. Alternatively, before the elastic film is bonded to the elastic cloth, it is processed into a mesh film with holes, and then bonded to the elastic cloth, which can also improve the air permeability.
綜上所述,本創作的特點是在於彈性布本身只在緯向具有可拉伸的回彈性,而在經向不具可拉伸的回彈性,並且彈性薄膜可直接或間接貼合彈性布,額外賦予彈性布更大的緯向回復性,得到在緯向具有彈性拉伸之多層式彈性透氣材料結構,尤其是,彈性布、彈性薄膜具有適當的透氣性,因此,很適合應用於貼身衣物、尿布、衛生用品的領域,改善舒適感,避免悶熱、潮濕而長疹子或發癢。In summary, the characteristics of this creation are that the elastic cloth itself has stretchable resilience only in the weft direction, but does not have stretchable resilience in the warp direction, and the elastic film can directly or indirectly fit the elastic cloth. In addition, the elastic cloth is given a greater weft recovery property, and a multilayer elastic breathable material structure having elastic stretch in the weft direction is obtained. In particular, the elastic cloth and elastic film have appropriate breathability, so it is suitable for use in personal clothing. , Diapers, hygiene products, to improve comfort and avoid sweltering, moist, rashes or itching.
