Description

一种高弹冰感面料及其在防晒上的应用
技术领域
本发明涉及功能性面料制备技术领域,具体涉及一种高弹冰感面料及其在防晒上的应用。
背景技术
随着科学技术不断地进步和生活水平不断提高,人们对服装的性能也有了新的需求。从以前讲究庇体保暖到后来讲究时尚,发展到今天人们开始关注起织物的功能性、环保性。在当今“温室效应”的大背景下,人们对凉感舒适的服装提出了需求,具有优良凉感性能的产品受到了人们的青睐。
针织产品由于其优异的舒适性和美观感,长期以来备受广大消费者的喜爱。在针织面料功能性的开发应用上,由于合成纤维原材料丰富、种类多和服用性能好等诸多优点,并与针织面料的优势结合,使其具有较好的服用性能及市场潜力。合成纤维中使用面最广的就是涤纶纤维,因为其具有强度高、耐磨性好、结实耐用和回潮率低等优点。近年来,人们开始重视涤纶纤维在凉感改性方面的研究。凉感涤纶长丝采用纳米技术,选取天然优质玉石粉、云母等矿石原料,通过将其加工成纳米级微粒,并使用亲水性切片与其一起纺丝加工而成。凉感涤纶纤维的截面形状大致呈不规则扁平状,有利于增强纤维的“毛细管吸水效应”,提高纤维的散热速率。以矿物原料作为添加剂的纤维和面料虽具有良好的纤维的散热速率,但内嵌填料式的纤维改性方法降低了纤维本身的力学性能,弹性较差,同时还增大了密度,增加面料克重,降低了面料的服用轻便性和舒适性。
发明内容
针对上述问题,本发明提供一种高弹冰感面料及其在防晒上的应用。
本发明的目的采用以下技术方案来实现:
一种高弹冰感面料,由纱线织造得到,所述纱线包括冰感聚乙烯纱线,所述冰感聚乙烯纱线的制备方法包括以下步骤:
(1)异形纤维制备
将PE切片进行干燥,控制切片含水率在0.03%以下,入螺杆挤出机中熔融,通过计量泵控制熔融物的出料量,经异形喷丝板喷丝,制得异形聚乙烯纤维;
(2)纤维改性
分别称取丙烯酸单体、2-丙烯酰胺-2-甲基丙磺酸单体和N,N-亚甲基双丙烯酰胺并溶解在去离子水中,充分搅拌混合后,加入功能单体和氧化还原引发剂,再次搅拌混合后得到聚合溶液,将所述聚合溶液密封并在室温下搅拌反应12-24h,反应完成后加入戊二醛,混合后制得第一整理溶液,将所述异形聚乙烯纤维浸入所述第一整理溶液中,取出后烘焙干燥制得改性纤维;
其中,所述丙烯酸单体、2-丙烯酰胺-2-甲基丙磺酸单体和N,N-亚甲基双丙烯酰胺在所述聚合溶液中的溶解浓度分别为4.6-5wt%、6.8-7wt%、0.3-0.4wt%;所述功能单体为1-乙基-3-甲基咪唑鎓乙酸盐,所述功能单体在所述第一整理溶液中的溶解浓度为3-4wt%;所述氧化还原引发剂为质量比例1:1的过硫酸钾和亚硫酸氢钠,所述戊二醛在所述第一整理溶液中的溶解浓度为2.5-3.8wt%;
(3)纱线改性
称取聚(偏二氟乙烯-co-六氟丙烯)并加入到丙酮中溶解,得到第二整理溶液,将包括有所述改性纤维的混纺纱线依次浸入所述第二整理溶液和去离子水中,真空干燥后制得所述冰感聚乙烯纱线。
一般材料中有较多基团的吸收如N-H、C-O等,其红外光的透过率很低,然而PE(聚乙烯)的红外吸收峰很窄,并且与人体辐射出的射线吸收峰相隔很远,其对红外光的吸收较弱,因此能确保较大的红外透过率,适合作为红外辐射散热织物材料,但其吸湿透气性较差,本发明通过凝胶改性纤维提高了纤维的服用性。
在一些优选的实施方式中,所述异形聚乙烯纤维的细度在40-200D。
在一些优选的实施方式中,所述PE切片的结晶度大于85%,密度在0.95-0.96g/cm3,熔融温度124-138℃。
在一些优选的实施方式中,所述异形喷丝板具有十字形或Y字形或W形或T字形异形截面。
在一些优选的实施方式中,所述第二整理溶液中所述聚(偏二氟乙烯-co-六氟丙烯)的溶解浓度在14-20wt%。
在一些优选的实施方式中,所述混纺纱线还包括有抗紫外蚕丝纤维,所述抗紫外蚕丝纤维的制备方法包括以下步骤:
S1、前处理
将蚕丝经脱胶处理后加入氯化钙溶液中溶胀,然后将溶胀的蚕丝经揉搓和梳理得到细纤维化的蚕丝纤维;
S2、耦合反应
将纳米氧化铝超声分散在过氧化氢溶液中,搅拌过夜后离心分离,去离子水离心洗涤后再次分散在乙醇水溶液中,加入聚乙二醇和四丁基钛酸酯,充分搅拌混合后,得到第三整理溶液,将所述细纤维化的蚕丝纤维浸入所述第三整理液中,在30-50℃下保温振荡0.5-1h,取出纤维并以去离子水洗涤,真空干燥制得所述抗紫外蚕丝纤维;
其中,所述第三整理溶液中纳米氧化铝的分散浓度在0.5-1.2wt%,所述聚乙二醇的溶解浓度在0.1-1wt%,所述四丁基钛酸酯的溶解浓度在0.8-1.8wt%。
在一些优选的实施方式中,所述混纺纱线中所述改性纤维与所述抗紫外蚕丝纤维的质量比例为(1.8-4):1。
在一些优选的实施方式中,所述氯化钙溶液的浓度为2-5wt%,溶胀温度为70-80℃,溶胀时间为5-20min。
在一些优选的实施方式中,所述细纤维化的蚕丝纤维的原纤化程度为20-35%。
本发明的另一方面在于提供一种所述高弹冰感面料的应用方法,具体是用作防晒用品的应用。
本发明的有益效果为:
针对现有的凉感面料难以兼具轻便舒适的问题,本发明以具有红外辐射散热性能的聚乙烯纤维为织物材料,在不外加添加剂的前体下提高了织物的散热性能,为提高面料的服用性,本发明通过设置为异形纤维提高纤维的比表面积,同时利用毛细管效应进行亲水吸湿改性提高纤维的吸湿透气性,具体的,本发明通过将具有吸湿性的离子液体1-乙基-3-甲基咪唑鎓乙酸盐分散在亲水性的聚(丙烯酸-co-2-丙烯酰胺-2-甲基丙磺酸)网络中,制得具有强吸湿性和粘附性的离子凝胶并对所述异形纤维进行表面改性,进而提高其吸湿性、亲肤性等服用性能,更进一步的,本发明还通过纱线表面修饰提高面料对太阳光的反/散射,进一步提升面料冰感,具体的,由于偏二氟乙烯-六氟丙烯共聚物和空气的折射率相差甚大,可以有效地散射阳光,包括紫外光、可见光和近红外光成分,从而实现高反射率,本发明基于该原理,通过溶液相转化法在纱线表面形成具有微纳结构的聚偏二氟乙烯-六氟丙烯薄膜,提高面料对太阳光的反/散射;更进一步的,本发明以具有高弹、柔性的天然蚕丝纤维作为复合混纺纤维以提高织物弹性,为降低天然蚕丝在紫外线波长区域的强烈吸收而对面料的遮阳和冰感效果的阻止作用,本发明以纳米氧化铝为改性剂,以四丁基钛酸酯为耦合剂对蚕丝纤维进行改性处理,其中,四丁基钛酸酯可以与氧化铝表面的羟基形成氢键,而且可以减少氧化铝颗粒的聚集,促进氧化铝纳米颗粒通过耦合反应与蚕丝纤维的耦合,同时,四丁基钛酸酯还可以与蚕丝的氨基酸形成强的共价键,四丁基钛酸酯水解形成的氧化钛进一步降低天然蚕丝在紫外线波长区域的吸收。
