Abstract
本发明提供一种防水加工布帛,其解决了聚乳酸树脂等以往的具有生物降解性的来自植物的成分的树脂的耐久性问题,舒适性也优异。所述防水加工布帛是在布帛的一面,通过涂覆法或接合法形成包含含有10~65重量%来自植物的成分的聚氨酯树脂膜的防水层而制成。
Description
技术领域
本发明涉及一种防水加工布帛,更具体地讲,涉及一种适合使用于运动用、特别是户外运动用的衣物、雨衣等的具有舒适性的防水加工布帛,另外,涉及一种为降低目前地球变暖对策中的环境负荷、含有有助于碳中和的来自植物的成分的防水加工布帛。
背景技术
关于包含来自植物的成分的防水加工布帛,例如在专利文献1中,公开了作为来自植物的成分使用有聚乳酸树脂的生物降解性良好的多孔质防水加工布帛。
但是,以往的生物降解性良好的防水加工布帛,在应用于运动用衣物、雨衣等情况时,在实际使用中担心在耐久性方面产生问题。即,现状是,在现在的一般的聚乳酸纤维中、在水解性评价试验(70℃×95%RH)中即便一周也难以保持强度、不能在要求耐久性的用途中使用,难以将作为来自植物的成分使用有聚乳酸树脂的生物降解性良好的多孔质防水加工布帛实用化。
专利文献1:特开2002-20530号公报
发明内容
本发明要解决的课题
本发明要提供一种防水加工布帛,所述防水加工布帛解决了仅通过上述聚乳酸树脂这样的来自植物的成分而不能解决的对水解的耐久性问题,具有舒适性。
用于解决课题的手段
本发明者经过潜心研究,结果发现,通过在布帛的单面利用涂覆 法或接合法、使用含有10~65重量%来自植物的成分的聚氨酯树脂膜,可以解决上述课题,从而完成本发明。
即本发明的防水加工布帛,在布帛的单面通过涂覆法或接合法形成包含含有10~65重量%来自植物的成分的聚氨酯树脂膜的防水层而成。
上述含有10~65重量%来自植物的成分的聚氨酯树脂膜,可以形成微多孔质膜或具有透湿性的无孔膜。
另外,可以在上述包含含有10~65重量%来自植物的成分的聚氨酯树脂的微多孔质膜上、层叠包含含有10~65重量%来自植物的成分的聚氨酯树脂的具有透湿性的无孔膜而形成上述防水层。
作为构成上述聚氨酯树脂的多元醇成分,可合适地使用蓖麻油二醇。
特别优选上述蓖麻油二醇为蓖麻油类聚醚聚酯二醇、平均羟基数为1.8~2.1个,羟基值为41~85mg KOH/g。
本发明的防水加工布帛优选耐水压为10kPa以上。
另外,优选通过JIS L 1099的A-1法得到的透湿度为104g/m2·hr以上。
而且,优选具有在温度70℃、湿度95%的条件下的水解性评价试验中经过3周后的耐水压的保持率为80%以上的耐久性。
本发明的防水加工布帛具有可合适地用于户外运动用衣物、雨衣等的舒适性。另外,通过因使用来自植物的成分所产生的碳中和,作为防止地球变暖对策的一个环节,有助于环境负荷的降低。
另外,作为聚氨酯树脂的多元醇成分,主要使用蓖麻油二醇,由此可以提高聚乳酸树脂等的具有生物降解性的来自植物的成分的树脂的问题即耐久性,在水解性评价试验(70℃×95%RH)中,可实现与由石油类成分构成的聚酯类聚氨酯同等的、或其以上的耐久性。
具体实施方式
本发明的防水加工布帛,如上所述,在单面利用涂覆法或接合法 通过含有来自植物的成分的聚氨酯树脂而形成有防水层。以下,对本发明进行更详细地说明。
1、对于布帛
作为用于本发明的防水加工布帛的布帛,可以合适地使用适合于使用目的等的布帛,但对其种类不做特别限定,作为例子,可举出尼龙纤维、聚酯纤维、聚酰胺纤维等的合成纤维;乙酸酯纤维等的半合成纤维;棉、麻、羊毛等的天然纤维,这些各种纤维可单独使用,也可2种以上混合使用。另外,对其组织也不做特别限定,可合适地使用织物、编织物、无纺布等。
2、对于防水层
作为形成防水层的含有10~65重量%来自植物的成分的聚氨酯树脂,可合适地使用作为多元醇成分主要使用2元的来自植物的多元醇等的来自植物的成分而合成的树脂。
作为2元的来自植物的多元醇,由于可以得到水解性优异的聚氨酯树脂,所以可合适地使用蓖麻油二醇。
蓖麻油为主要由下式表示的蓖麻醇酸的甘油三酯。
(化学式1)
蓖麻醇酸为具有下式表示的结构的化合物。
(化学式2)
本发明中所谓的蓖麻油二醇为来自蓖麻油的二醇,其中优选为蓖麻油类聚醚聚酯二醇,平均羟基数为1.8~2.1个,羟基值为41~85mgKOH/g。可特别合适地使用平均羟基数为1.95~2.05个的二醇。如果 羟基数超过2.1个,则由于产生3元的多元醇的支化或交联结构,因此难以得到适合于用于形成树脂膜的涂覆的聚氨酯树脂。即,本发明中使用的聚氨酯树脂,优选结构为线状,不太具有支化或交联结构,具有可以涂覆在布帛上的溶液的粘性。如果支化结构增加,则粘性增大,不适于涂覆。另外,如果形成交联结构,则即使是极微量的,也发生粘性变化,即使是少量的,粘性变化也大,而且如果交联量增加,则不能得到氨基甲酸酯树脂溶液。
聚氨酯树脂中的来自植物的成分的比例,从减轻环境负荷的观点考虑优选较大的比例,但为提高聚氨酯树脂膜的性能来得到作为本发明目的的防水加工布帛,使下限为10重量%、上限为65重量%。从减轻环境负荷的观点考虑更优选为25~65重量%。
3、对于防水加工布帛的特性及制法
本发明的防水加工布帛,从实用上的防水的观点考虑,优选耐水压为10kPa以上。
而且,从实用上的耐久性的观点考虑,优选在水解性评价试验(ジヤングルテスト、70℃×95%RH)中经过3周后的耐久性保持率为80%以上。
本发明中,如上所述作为聚氨酯的原料的2元的多元醇,通过使用来自蓖麻油的上述聚醚聚酯多元醇,可以实现防水加工布帛的耐水压在水解性评价试验中经过3周后的保持率为80%以上。而且,可得到即使经过15周后耐水压的保持率也为50%以上这样的、使用通常的聚酯多元醇情况下的5倍以上的、非常有耐久性的防水加工布帛。
另外,本发明的防水加工布帛,希望作为透湿度在A-1法中具有104g/m2·hr以上,或者在B-1法中具有104g/m2·hr以上。
对含有来自植物的成分的聚氨酯树脂膜的透湿性的赋予,可以通过利用湿式法将其聚氨酯树脂作成微多孔质膜。另外,为用无孔膜赋予透湿性,例如可在含有来自植物的成分的聚氨酯树脂的聚合中共聚合包含聚乙二醇的多元醇,通过干式法形成树脂膜。
另外,可通过在微多孔质膜上层叠具有透湿性的无孔膜,得到更 高的耐水压和透湿度。
作为用于得到上述含有来自植物的成分的聚氨酯树脂的方法,例如可以采用如下方法:在二甲基甲酰胺(DMF)、二甲基亚砜(DMSO)等代表的极性溶剂,甲基乙基酮(MEK)、甲苯、二甲苯等的溶剂中,溶解蓖麻油二醇等的2元的来自植物的多元醇,在其中添加2元的异氰酸酯(六亚甲基二异氰酸酯、异佛尔酮二异氰酸酯、二苯基甲烷二异氰酸酯:MDI、加氢MDI等),使其充分反应,调制成在末端具有异氰酸酯或羟基的预聚物,然后添加二醇(来自石油的乙二醇、丙二醇、丁二醇等,来自植物性的1,3-丙二醇、1,2-己二醇等)、或2元的异氰酸酯(六亚甲基二异氰酸酯、异佛尔酮二异氰酸酯、二苯基甲烷二异氰酸酯(MDI)、加氢MDI等),用链延长反应提高聚合度。但是,本发明中使用的聚氨酯树脂的合成方法不限定于上述方法。
上述中,在使2元的来自植物的多元醇和2元的异氰酸酯反应而形成预聚物时,根据需要,除了2元的来自植物的多元醇外,也可以对其以外的多元醇,例如聚酯多元醇、聚醚多元醇进行共聚合。更具体地讲,可以共聚合作为2元的来自石油的多元醇的聚己二酸乙二醇酯、聚己二酸丁二醇酯、聚己内酯二醇、聚乙二醇、聚丁二醇、聚四亚甲基二醇等。或者也共聚聚碳酸酯多布醇、有机硅类多元醇、氟类多元醇、聚酰胺类多元醇等而使用。这些来自植物的多元醇以外的多元醇可以以多元醇总量中50重量%(固体分比)以下的比例进行混合,但也为了不降低来自植物的比率,混合量希望为25重量%(固体分比)以下。
对于本发明的防水加工布帛的制造方法,作为向布帛层叠含有来自植物的成分的聚氨酯膜的防水层的方法,有在布帛上直接进行涂覆的方法(涂覆法)、单独形成防水层后用粘合剂将其层叠在布帛上的方法(接合法)。
上述涂覆方法中,可以使用刮刀涂覆、辊式刮刀涂覆、逆辊涂覆等的各种的涂覆方法。
另外,作为接合法例如可以使用如下方法:将在脱模纸上通过涂 覆等形成的防水层用粘合剂进行点或整面粘合而层叠于布帛上后剥离脱模纸的方法,但不限定于这种方法。
作为层叠具有透湿性的防水层的方法的优选方式的实例,可举出以下的方法。
(1)将含有来自植物的成分的聚氨酯树脂溶解在可溶于水的极性溶剂(由二甲基甲酰胺:DMF、二甲基亚砜:DMSO等代表)中,将形成的聚氨酯树脂溶液涂覆在布帛上,使其在水中或含有极性溶媒的水溶液中进行湿式凝胶化,形成一并具有透湿性和防水性的微多孔质膜的方法。
(2)将含有来自植物的成分的聚氨酯树脂通过共聚合包含聚乙二醇的多元醇而形成透湿性的聚氨酯树脂,将用溶解该树脂的溶剂进行溶解而成的聚氨酯树脂溶液涂覆在布帛上,干燥该溶剂,形成一并具有透湿性和防水性的无孔质膜的方法。
实施例
以下,通过实施例进一步具体地说明本发明,但本发明不限定于以下实施例。另外,作为包含以下实施例的本说明书等中的各性能的测定方法,采用以下的方法。
(测定方法)
(1)耐水压:依照JIS规格L 1092进行测定。

[表1]
从表1所示结果可知,本发明实施例的防水加工布帛不仅具有均优异的透湿性及防水性,而且在温度70℃、湿度95%的条件下的水解性评价试验中,具有经过3周后的耐水压的保持率为80%以上、即使经过18周后还为60%以上的这样的极其优异的耐久性。与此相对,使用来自石油的聚氨酯树脂、来自植物的成分的比率为0重量%的比较例1的布帛,与实施例的布帛相比,耐久性、耐碱性差,来自植物的成分的比率超过65重量%的比较例2的布帛,透湿性低、耐久性与实施例的布帛相比也稍差。
产业上的可应用性
本发明的防水加工布帛,解决了以往的聚乳酸树脂等的具有生物降解性的来自植物的成分的树脂的耐久性问题,舒适性也优异,因此可合适地用于运动用、特别是户外运动用衣物、雨衣等。
