Description

多層構造布帛及其製造方法及纖維製品
本發明係關於透濕性、輕量性、伸縮性、薄度優異的多層構造布帛及其製造方法及纖維製品。
以往，在衣料用途中，已提案出以塗覆或層合之手段將樹脂膜積層於梭織物或針織物之布料的單面而得之具有防風性之透濕防水性布帛(例如專利文獻1)。
另一方面，在透濕防水性布帛中，正謀求不僅是透濕性，輕量性、伸縮性、薄度亦優異的著用舒適性佳的布帛。
然而，迄今為止甚少提案出透濕性、輕量性、伸縮性、薄度優異的布帛。 [先前技術文獻] [專利文獻]
專利文獻1：日本專利特開2010-201811號公報
[發明所欲解決之課題]
本發明係有鑑於上述背景而完成者，其目的在於提供透濕性、輕量性、伸縮性、薄度優異的多層構造布帛及其製造方法及纖維製品。 [解決課題之手段]
本發明者為了達成上述課題而致力檢討之結果，發現藉由對所使用之纖維的纖度或形狀、布帛的構造等巧妙地下功夫，可獲得透濕性、輕量性、伸縮性、薄度優異的多層構造布帛，並藉由進一步反覆致力檢討而完成本發明。
如此，根據本發明，可提供「一種多層構造布帛，其係包含布帛及樹脂膜之多層構造布帛，其特徵為 前述布帛為單層圓形針織物，該單層圓形針織物包含總纖度44dtex以下的非捲縮合成纖維複絲，針織密度為45～130個緯圈／2.54cm且55～120個經圈／2.54cm」。
此時，前述非捲縮合成纖維複絲較佳係由聚酯纖維或聚醯胺纖維所組成。此外，在前述非捲縮合成纖維複絲中，拉伸強度較佳為4.0cN／dtex以上。此外，前述非捲縮合成纖維複絲較佳為再生紗。此外，前述單層圓形針織物較佳係具有天竺組織。此外，前述樹脂膜較佳為胺基甲酸酯膜或聚酯膜或聚碳酸酯膜或氟系膜。此外，在前述樹脂膜中，厚度較佳為15μm以下。
在本發明之多層構造布帛中，基重較佳為79g／m2 以下。此外，厚度較佳為0.3mm以下。此外，透濕性較佳為20000g／m2 ・24h以上。
此外，根據本發明，可提供前述多層構造布帛之製造方法，其係使用46隔距以上的單面圓形針織機獲得單層圓形針織物後，將樹脂膜積層於該單層圓形針織物。
此外，根據本發明，可提供一種纖維製品，其係使用前述多層構造布帛所形成，且選自運動服、戶外活動服、雨衣、男裝、女裝、作業衣、防護服、人工皮革、鞋、包、窗簾、帳篷、睡袋、防水片、傘及汽車座椅所組成之群組之任一者。此時，在前述纖維製品中，重量較佳為150g／1件以下。 [發明效果]
根據本發明，可獲得透濕性、輕量性、伸縮性、薄度優異的多層構造布帛及其製造方法及纖維製品。
以下，針對本發明之實施形態詳細地進行說明。本發明之多層構造布帛包含由單層圓形針織物所組成之布帛及積層於該布帛而成之樹脂膜，該單層圓形針織物包含總纖度44dtex以下的非捲縮合成纖維複絲，針織密度為45～130個緯圈／2.54cm且55～120個經圈／2.54cm。
在此處，樹脂膜可積層於前述布帛的兩面，亦可積層於單面。較佳為後者(即，多層構造布帛具有2層構造)。
在前述非捲縮合成纖維複絲中，在總纖度大於44dtex之情況，輕量性或透濕性會受損，因而較不佳。較佳的總纖度為8～40dtex(更佳為8～25dtex，再佳為8～19dtex)。在該種非捲縮合成纖維複絲中，單纖維纖度並無特別限定，較佳係單纖維纖度0.9～2.8dtex。絲數較佳為15～300根。
前述非捲縮合成纖維複絲可為空氣加工紗、並列型複合纖維，重要的是為非捲縮。若為假撚捲縮加工紗等捲縮紗，則布帛的厚度變大而較不佳。另外，前述非捲縮合成纖維複絲較佳為長纖維。
此外，在前述非捲縮合成纖維複絲中，若拉伸強度為4.0cN／dtex以上(較佳為4.2cN／dtex以上，更佳為4.5cN／dtex以上，再佳為5.5～10.0cN／dtex以上)，則多層構造布帛的撕裂強力提升而較佳。另外，為了獲得拉伸強度為4.0cN／dtex以上的聚對酞酸乙二酯纖維，可藉由例如日本專利特開2013-119689號公報或日本專利特開2010-168675號公報中所記載之製造方法進行製造。即，將固有黏度為0.7～1.5的聚對酞酸乙二酯於290～310℃進行熔融，自具有圓斷面的吐出孔之紡紗管頭吐出熔融聚合物，以冷風冷卻後，以上油噴嘴賦予油劑，在延伸後進行捲取之方法(或者，以未延伸紗之形式捲取後，進行延伸之方法)。
此外，在前述非捲縮合成纖維複絲中，單纖維橫斷面形狀並無特別限定，可為圓、三角、扁平、中空等公知的斷面形狀。
作為形成前述非捲縮合成纖維複絲之聚合物的種類，並無特別限定，較佳為聚酯、聚醯胺等。經材料再生或化學再生之聚酯或聚醯胺等亦較佳。再者，亦可為如日本專利特開2004-270097號公報或日本專利特開2004-211268號公報中所記載之使用包含特定的磷化合物及鈦化合物之觸媒所獲得之聚酯。在該聚合物中，在無損本發明之目的之範圍內亦可視需要包含1種或2種以上微細孔形成劑、陽離子染料可染劑、抗著色劑、熱安定劑、螢光增白劑、消光劑、著色劑、吸濕劑、無機微粒子。
在前述單層圓形針織物中，亦可包含前述非捲縮合成纖維複絲以外之纖維，最佳係僅以前述非捲縮合成纖維複絲構成。
在前述單層圓形針織物中，重要的是具有45～130個緯圈／2.54cm且55～120個經圈／2.54cm的針織密度。若針織密度大於該範圍，則會有厚度變大之疑慮。相反地，若針織密度小於該範圍，則會有布帛的撕裂強力等降低之疑慮。
此外，在前述單層圓形針織物中，基重就輕量性之方面而言較佳為50g／m2 以下(更佳為20～41g／m2 )。若該基重大於50g／m2 ，則會有輕量性受損之疑慮。
在前述單層圓形針織物中，前述圓形針織物的組織為緯編組織，平針織(天竺)、鹿點花紋針織、1×1天竺等，並無特別限定，若考慮到基重、厚度、抗勾絲性、成本等，則較佳為天竺組織。
作為前述單層圓形針織物之製造方法，較佳係採用前述非捲縮合成纖維複絲，使用46隔距以上(較佳為46～80隔距)的單面圓形針織機進行製編。
對於該種單層圓形針織物，亦可適宜施以通常的染色加工、減量加工、起毛加工、撥水加工、蓄熱加工、吸汗加工等後加工。此時，用於染色之染料為分散染料、陽離子性染料、酸性染料等，並無特別限定，由於陽離子性染料必須選擇能夠以陽離子性染料染色之纖維，因而較宜使用泛用性更高的分散染料。此外，作為撥水加工所使用之撥水劑，可使用石蠟系撥水劑或聚矽氧烷系撥水處理劑、氟系撥水處理劑、不含氟之撥水劑等公知者。該處理亦可以一般所施行之壓染法、噴霧法等公知的方法施行。
本發明之多層構造布帛為樹脂膜積層於前述單層圓形針織物而成者。此時，前述樹脂膜較佳為胺基甲酸酯膜或聚酯膜或聚碳酸酯膜或氟系膜。作為樹脂膜的厚度，就輕量性或透濕性之方面而言，較佳為15μm以下(更佳為5～15μm)。為了減輕著用時之摩擦，亦可將樹脂部分地印至2層構造的膜面。
在此處，胺基甲酸酯樹脂膜可列舉由具有透濕性之胺基甲酸酯樹脂所組成之膜、胺基甲酸酯樹脂塗層等，並無限定。作為氟系膜，可列舉聚四氟乙烯樹脂膜(例如Gore-Tex公司製)等，並無限定。再者，亦可為丙烯酸系樹脂塗層。
作為聚酯膜，較宜使用由聚醚-酯系彈性體或PBT(聚對酞酸丁二酯)所組成之聚酯膜。
上述膜可為多孔質膜，亦可為以具有透濕性之聚酯作為主成分之無孔質膜。在對聚酯賦予透濕性時，並無特別限定，較宜使用將聚乙二醇等吸濕性材料共聚成聚酯之方法。可視需要添加氧化矽、氧化鈦、氮化鈦、氮化硼、碳化硼、碳化矽、氮化矽、鈦酸鉀、氧化鋅、氧化鋁、硼酸鋁等無機微粒子，或丙烯酸系、胺基甲酸酯系、聚酯系、聚醯胺系等有機微粒子。再者，可添加用於附加顏色之著色用顏料、用於使皮膜強度提升之交聯劑、抗氧化劑、增黏劑等。此外，膜可藉由層合而積層於底布。較佳為接著劑。
如此所獲得之多層構造布帛係透濕性、輕量性、伸縮性、薄度優異。此時，多層構造布帛的基重較佳為79g／m2 以下(更佳為20～79g／m2 ，特佳為30～68g／m2 )。此外，多層構造布帛的厚度較佳為0.3mm以下(更佳為0.1～0.3mm，特佳為0.11～0.21mm)。此外，多層構造布帛的透濕性較佳為20000g／m2 ・24h以上(更佳為20000～150000g／m2 ・24h，特佳為30000～100000g／m2 ・24h)。
其次，根據本發明，可獲得一種纖維製品，其係使用前述多層構造布帛所形成，且選自運動服、戶外活動服、雨衣、男裝、女裝、作業衣、防護服、人工皮革、鞋、包、窗簾、帳篷、睡袋、防水片、傘及汽車座椅所組成之群組之任一者。
由於該種纖維製品係使用前述多層構造布帛，故透濕性、輕量性、伸縮性、薄度優異。此時，在前述纖維製品中，重量較佳為150g／1件以下(更佳為10～150g／1件)。 [實施例]
