Description
技术领域
本发明涉及与热熔粘合剂的粘合特性得以改善的氨纶纤维及其制造方法。具体而言,本发明涉及如下的氨纶纤维及其制造方法,所述氨纶纤维及其制造方法在尿布的制作工艺中,通过热熔粘合剂提供氨纶纤维与聚丙烯无纺布或聚乙烯膜之间的改善的粘合力,从而可改善尿布的生产效率并改善与热熔粘合剂的粘合特性。
背景技术
与一般的医用纤维相比,现有的医用氨纶纤维因其丝间粘着性更大,存在如下缺点:倒丝性能差、在整经及编织作业等后续加工工艺中断丝较多、且因静电而产生不均匀的丝间张力。因此,为改善上述问题,一般是通过向聚合物内添加防粘剂提高其性能。
但是,在尿布的制作工艺中,为降低用于制作尿布的氨纶纤维的粘着性而添加的防粘剂存在如下问题:氨纶纤维与聚丙烯无纺布或聚丙烯膜的通过热熔粘合剂的粘合力降低(Slip)。因此,氨纶纤维不能恰当地粘合至尿布,从而报道了无法维持尿布的恰当形态的问题。
为改善与热熔粘合剂的粘合力,在生产氨纶纤维时,向乳剂中添加增粘剂或向聚合物内添加热塑性聚氨酯或松香类化合物等。但是向乳剂中添加增粘剂时,因乳剂内的不均匀涂布而存在丝表面的涂布不均匀的问题,同时,向聚合物内添加热塑性聚氨酯时,无改善粘合力的效果,而在添加松香类化合物时,因氨纶纤维的倒丝张力的提高而出现倒丝性变弱的问题。因此,向聚合物内添加烃类树脂的单体、聚合物或其衍生物,在倒丝张力方面不存在问题,且可改善粘合特性,从而改善粘合力降低的问题。

具体实施方式
下面将对本发明的优选实施方式进行描述。然而,本发明的实施方式能够以多种不同的形式进行变形,而本发明的范围不应受到将在下文中描述的实施方式的限制。
本发明实施方式的目的是为了帮助本领域技术人员更好地理解本发明。
另外,在整个申请文件中,特别是在无相反记载时,“包括”一些组成要素时意味着还可包含另外的其它组成要素,而非是排除其它组成要素。
本发明的目的在于,在尿布的制作工艺中,改善氨纶纤维与聚丙烯无纺布或聚乙烯膜的通过热熔粘合剂的粘合力。
本发明的特征在于,在尿布的制作工艺中,为提高氨纶纤维与聚丙烯无纺布或聚乙烯膜的通过热熔粘合剂的粘合力,添加约0.1wt%至约30wt%的如下物质作为增粘剂,以此改善粘合特性:具有上述化学结构1的乙烯-乙酸乙烯酯的单体、聚合物及其衍生物,或者具有上述化学结构2的具有9个碳原子的烃类树脂的单体、聚合物及其衍生物,或者具有上述化学结构3的具有5个碳原子的烃类树脂的单体、聚合物及其衍生物,或者C5/C9烃类树脂的单体、共聚物及其衍生物。
根据本发明,如果当所添加的增粘剂(乙烯-乙酸乙烯酯的单体、聚合物及其衍生物,或者具有9个碳原子的烃类树脂的单体、聚合物及其衍生物,或者具有5个碳原子的烃类树脂的单体、聚合物及其衍生物,或者C5/C9烃类树脂的单体、共聚物及其衍生物)的含量小于0.1wt%时,无法观察到所需的改善粘合特性的效果,而如果加入的增粘剂的含量大于30wt%时,则在生产原丝之后,无法确保氨纶原丝所需的物理性能。
氨纶纤维是具有85wt%以上的氨酯键的高弹性的聚氨酯类纤维。氨纶纤维通过如下方式制造:干法纺丝,通过喷嘴压出聚氨酯树脂组合物的纺丝原液,利用加热气体挥发溶剂并干燥;湿法纺丝,通过纺丝浴洗脱溶剂的同时固化聚合物;化学纺丝,在含有胺扩链剂的反应液中,通过喷嘴压出具有异氰酸酯的预聚物溶液进行扩链反应;或熔融纺丝,将聚氨酯树脂组合物在加热熔融状态下通过喷嘴压出并进行冷却。
本发明所述的氨纶纤维的制造方法包括如下步骤:在氮气气氛下,使聚醚多元醇与芳香族二异氰酸酯进行反应,制备聚氨酯预聚物;将上述聚氨酯预聚物溶于溶剂之后,添加脂肪族二胺,制备聚氨酯脲溶液。另外,相对于该聚合物的固体成分,通过添加如下添加剂制备最终的纺丝原液:约1wt%的作为抗氧化剂的三甘醇-双-3-(3-叔丁基-4-羟基-5-甲基苯基)丙酸酯、约2wt%的作为耐光剂的二氧化钛。
聚醚多元醇可使用聚四亚甲基醚二醇、聚丙二醇、聚碳酸酯二醇等,而聚醚多元醇的分子量优选为1000至3100。本文中,若分子量低于1000,则因纤维的拉伸度低而存在氨纶纤维的功能恶化的问题,与此相反,若分子量高于3100,则因结晶度过高而无法表现出正常的弹性。
有机二异氰酸酯可使用二苯基甲烷-4,4'-二异氰酸酯、六亚甲基二异氰酸酯、甲苯二异氰酸酯、二异氰酸丁酯、氢化二苯基甲烷-4,4'-二异氰酸酯、亚甲基-双(4-苯基异氰酸酯)、2,4-甲苯二异氰酸酯、亚甲基-双(4-环己基异氰酸酯)、异佛尔酮二异氰酸酯、四亚甲基-p-亚二甲苯基二异氰酸酯及其混合物等。
用作扩链剂的二胺可使用例如:乙二胺、丙二胺、肼、1,4-己二胺、氢化-m-苯二胺(HPMD)、2-甲基-戊二胺(MPMD)等。扩链剂为HPMD,MPMD,和/或与1,2-丙二胺混合的乙二胺、1,3-丙二胺及1,4-环己二胺中的一个或多个。另外,将单胺用作链终止剂,所述单胺例如二乙胺、单乙醇胺、二甲胺等。
下面,将通过实施例对本发明进行更详细的说明,但是本发明并不受限下述实施例。

在将预聚物冷却至室温之后,添加4811g二甲基乙酰胺进行溶解,获得聚氨酯预聚物溶液。
接下来,将43.3g乙二胺和13.4g的1,2-丙二胺、5.7g二乙胺溶于829g二甲基乙酰胺中,并在9℃以下添加至上述预聚物溶液中,从而获得聚氨酯溶液。相对于聚合物的固体成分,添加如下添加剂以制备纺丝原液:1wt%的作为抗氧化剂的三甘醇-双-3-(3-叔丁基-4-羟基-5-甲基苯基)丙酸酯、2wt%的作为耐光剂的二氧化钛。另外,通过添加0.5wt%的作为增粘剂的乙烯-乙酸乙烯酯聚合物,制备纺丝原液。
