Description

一种轻质保暖防钻绒面料及其制备方法
技术领域
本发明涉及一种轻质保暖防钻绒羽绒服面料的制备方法，属于功能纺织品技术领域。
背景技术
近几年，市场上比较流行超轻薄面料的羽绒服，轻型羽绒服兼具了保暖、轻便、时尚等多重性能，携带也比较方便，但是它的缺点是经常会有钻绒的现象出现，为了解决纤维细度30D以下，经纬密度380T以下的超轻薄羽绒服面料特别容易钻绒的问题，通过染色、定型、轧光、贴膜等工艺的协同作用，使布料门幅在加工过程中反复发生拉伸一回缩，使纬线弯曲为S型，填补纤维间的空隙，达到更好的防钻绒效果。同时在轧光过程中添加化学助剂，使布料纤维的细丝更分散、平滑，能承受更高的轧光温度，更容易被压扁平，更好的填补纤维间空隙，减少对光的散射，因而也就同时提高了布料的防钻绒性能、光泽度和柔软度，同时研究纱线细度、密度、含绒量、缝制用针、缝制工艺以及充绒工艺等因素对防钻绒效果的影响。
已有研究大多通过贴胶或树脂整理的方式来解决钻绒问题，如中国发明专利CN110029504A提供的一种防钻绒面料，它包括基布层和多孔树脂层，多孔树脂层中含有丙烯酸类树脂和有机硅类树脂。中国发明专利CN107245880A提供的一种羽绒服面料防钻绒的处理方法，采用柔软抗皱、轻薄强度高的丝光棉制成的织物，使用二氧化硅与辛酸锌复配的拒水整理剂对其进行拒水处理，再通过高压摩擦轧光保持织物的柔软和光泽度，通过改性涂层胶的涂覆。中国发明专利CN111134408A提供了一种防钻绒面料及制备方法，将面布和底布通过上胶分别与一层高分子薄膜热压粘合制得两层防绒膜层，再将面布和底布(面布的面朝上，底布的面朝下放置)送入热压机的立体雕刻花辊进行热压粘合工艺，实现面布与底布的粘合，立体雕刻花辊花型呈现效果后，在空腔里注入冲绒，制得防钻绒面料。
虽然现有的防钻绒技术囊括多个方面，一定程度减少了钻绒现象，但仍然存在使用后变硬、不透气、脱膜、防钻绒效果不耐水洗的问题，轻薄面料的保暖性也不能满足需要，这些问题仍一直困扰着广大生产者和消费者。
发明内容
本发明针对现有技术存在的不足，提供一种具有优异的手感及防钻绒性、耐洗涤性和透气性，制备工艺简单的轻薄保暖防钻绒面料及其制备方法。
实现本发明目的的技术方案是提供一种轻质保暖防钻绒面料的制备方法，包括以下步骤：
（1）用远红外细旦化纤加捻低弹丝为纬纱、低熔点细旦涤纶低弹包覆丝为经纱，上浆后交织成40～60gsm的斜纹梭织纺织品；
（2）将纺织品浸渍在浓度为20～40g/l的烧碱溶液中，打卷室温堆置24～48h，经洗涤烘干预处理后备用；
（3）水热法一步制备掺氮碳量子点：以柠檬酸为碳源加入到去离子水中，超声分散处理配成浓度为0.05～0.3g/l的透明溶液；以无水乙二胺为氮源，缓慢加入到碳源溶液中，至pH为8.5～9.5，常温条件下搅拌15～30 min，按体积比1：1加入去离子水后，将反应液置于不锈钢外套密封的聚四氟乙烯内衬中，在温度为150～180 ℃的条件下进行水热反应6～8 h，将得到的产物离心除去不溶杂质，得到自分散掺氮碳量子点溶液；
（4）将步骤（2）预处理后的纺织品在步骤（3）量子点溶液稀释成浓度为5～10%的轧液中进行轧-烘-焙处理，轧液率为100～150%，预烘温度为80～110 ℃，焙烘温度为120～140 ℃，得到含有掺氮碳量子点的纺织品；
（5）在涂铝设备中将步骤（4）制备的纺织品的反面进行热压涂铝，控制温度150～180℃，铝点直径为0.5～1mm，得到一种轻薄保暖防钻绒面料。
本发明所述的一种轻薄保暖防钻绒面料的制备方法，其远红外细旦化纤为20～40D的涤纶或锦纶；低熔点细旦涤纶低弹包覆丝为20～40D的涤纶包覆10～20D的氨纶，涤纶熔点为245～250℃。
本发明技术方案还包括按上述制备方法得到的一种轻质保暖防钻绒面料。
羽绒的钻出主要与面料自身的致密性以及使用过程中的静电吸附有关，本发明在纳米尺度上通过氮掺碳量子点的微孔填埋及抗静电效果，同时与低熔点涤纶热压致密相协同构筑羽绒防护墙，远红外涤纶与铝点的协同增效，解决了防钻绒及轻薄保暖的问题。本发明利用上述原理，针对现有技术在面料防钻绒保暖方面存在的不足，通过解决面料自身的致密性以及使用过程中的静电钻绒问题，从而阻止羽绒钻出，钻绒数量可达5根以下，纳米微孔效应不影响手感和透气性，同时面料兼具保暖保健效果。
与现有技术相比，本发明的有益效果在于：所得纺织品轻薄透气，而且具有持久高效的防钻绒效果，同时具有优异的保暖功能，比普通面料温度上升2.3 ℃。本发明提供的远红外防钻绒羽绒服面料的制备方法，具有简易快捷、设备要求低等优势，有利于工业化生产。
