Description

一种轻质保温面料及其制备方法
技术领域
本发明涉及层状产品领域，具体涉及一种轻质保温面料及其制备方法。
背景技术
面料五花八门，面料的制备日新月异，针对面料的改革与创新也在不断推陈出新。有针对面料纺织纤维的探索与创新，目前的纺织纤维种类繁多，包括天然纤维和合成纤维，针对不同的面料需求，选择各种纤维制备面料。也有针对各种功能性面料需求，选择在面料纺织过程中，添加不同填料，用以增强面料的各项性能，但是这种方法在增加面料功能性的同时，也不可避免地存在着填料溶出的问题，造成皮肤过敏、面料合格率下降等问题。
保温面料是其中的一个研究热点。传统保温面料不可避免存在着面料密度厚的问题，给人体带来沉重的穿着体验。因此，同时解决保温、质轻、无刺激的面料具有广阔的市场前景。
中国专利CN201110049427.7公开了一种保温面料，依次包括棉布层、反射层、保暖层、空腔层和装饰层，棉布层位于保温面料的最里层，装饰层位于保温面料的最外层，空腔层位于装饰层的里侧，保暖层为中间层，保暖层中有保温材料。但是该专利制备得到的保温面料的厚度大、透气性差、一般不作为穿着面料。
因此，需要制备一种保温、质轻、无刺激的面料。
发明内容
本发明针对上述问题，提供一种轻质保温面料及其制备方法。
本发明解决上述问题所采用的技术方案是：一种轻质保温面料，包括吸热层、填充层和透水层；吸热层在横截面为蜂窝结构；透水层在横截面为Y形；吸热层和透水层之间采用填充层；填充层采用长绒棉与聚乙烯醇纤维混纺而成；吸热层、填充层、透水层通过缝制连接。
其中，面料采用多层面料复合而成，有利于面料轻质保温功能的实现；吸热层采用棉纤维和氨纶纤维混纺而成，热传导率低，使得热量不易散出；透水层位于面料内层，由于该层面料由棉纤维、丙纶纤维、乙纶纤维混纺而成，丙纶纤维、乙纶纤维的疏水效果好，有利于汗水蒸汽的散发，棉纤维有利于汗水蒸汽的吸收，从而实现透水功能；填充层采用长绒棉与聚乙烯醇纤维混纺而成，再经过水洗步骤，使水溶性的聚乙烯醇纤维去除，使得长绒棉的蓬松程度上升，面料的空气截留率提高，进一步提高保温程度，并且使得填充层的单位重量下降，进一步降低了面料的重量；吸热层在横截面为蜂窝结构，透水层在横截面为Y形，通过面料的不对称结构，降低空气的透过率，提高面料的保温性，并且透水层在横截面为Y形增强了其透水性，人体穿着时不感到闷热不舒服，提高了舒适效果。
进一步地，吸热层采用棉纤维和氨纶纤维混纺而成。
更进一步地，氨纶纤维的混纺比例是1.5％～4％。
进一步地，透水层采用棉纤维、丙纶纤维、乙纶纤维混纺而成。
更进一步地，棉纤维的混纺比例是95％～97％。
更进一步地，丙纶纤维和乙纶纤维的混纺比例是1：0.2～0.5。
进一步地，填充层中，聚乙烯醇纤维的混纺比例是3％～6％。
本发明的另一发明目的，在于提供一种上述轻质保温面料的制备方法，包括以下步骤：
步骤S1，吸热层纺织：将棉纤维和氨纶纤维按所述比例混纺，制成直径为10μm～25μm的混纺纤维，将制得的混纺纤维纺织成横截面为蜂窝结构的面料，即为吸热层；
步骤S2，填充层纺织；将长绒棉与聚乙烯醇纤维按所述比例混纺，制成直径为5μm～15μm的混纺纤维，将制得的混纺纤维经过经纬交织纺织制成克重为30g/m2～50g/m2的面料，经过水洗，使混纺纤维中的聚乙烯醇纤维去除，干燥后，得到填充层；
步骤S3，透水层纺织；将棉纤维、丙纶纤维、乙纶纤维按所述比例混纺，制成直径为20μm～40μm的混纺纤维，将制得的混纺纤维纺织成横截面为Y形的面料，即为透水层；
步骤S4，将制得的吸热层、透水层与至少一层填充层通过缝制连接，形成所述轻质保温面料。
进一步地，步骤S1中，吸热层的克重为70g/m2～100g/m2。
进一步地，步骤S3中，透水层的克重为50g/m2～70g/m2。
本发明的优点是：
1.本发明制得的面料保温、质轻、无刺激；
