Description
技术领域
本申请涉及布料的领域，更具体地说，它涉及一种可降解的抗静电无纺布。
背景技术
无纺布又称不织布，是由定向的或随机的纤维构成。因具有布的外观和某些性能而称其为布。无纺布具有防潮、透气、柔韧、质轻、不助燃、容易分解、无毒无刺激性、色彩丰富、价格低廉、可循环再用等诸多优点。
无纺布在使用和洗涤过程中，因不断经受外力的作用而容易发生变形，产生折痕，导致无纺布平整度降低，影响无纺布的使用，同时也影响无纺布的外观。
为了提高所制水刺无纺布的抗皱性，本领域通常对合成纤维或复合纤维进行改性，提高合成纤维或复合纤维的抗皱能力，从而提高由合成纤维或复合纤维制成的无纺布的抗皱能力。
涤纶为无纺布材料的一种，涤纶又称聚酯纤维，是由机二元酸和二元醇缩聚而成的聚酯经纺丝所得的合成纤维，其具有较好抗皱性和保形性，在一定工艺下可降解，且降解形成的酸和醇可回收再利用，绿色环保。
涤纶纤维虽具有较好抗皱能力，但涤纶纤维吸湿性较差，其表面过于干燥是其容易起静电的原因之一，带静电的涤纶织物影响其穿着舒适度。
发明内容
为了提高涤纶纤维的抗静电能力，本申请提供一种可降解的抗静电无纺布。
本申请提供的一种可降解的抗静电无纺布，采用如下的技术方案：
第一方面，本申请提供一种可降解的抗静电无纺布，采用如下的技术方案：
一种可降解的抗静电无纺布，采用如下方法制备：
S1，将改性涤纶纤维、大豆蛋白纤维依次经过混棉机混合、开松机松散后进入棉箱、梳理机梳棉、成网机进行成网；
S2，依次经过针刺机针刺加固、开边机剪裁多余的棉网、热压三辊机压合，切刀成卷，形成无纺布；
S3，置于放布架进行放布，依次经过上胶池上胶、红外定型、洗槽水洗、烘箱加热、切刀成卷得到抗静电无纺布；
所述改性涤纶纤维的制备方法如下：
S1，改性剂的配制：
S11，按重量份计，称取90-110份假酸浆子，第一次浸泡于550-650份水中，在40-50℃下浸泡20min，将甲酸浆子取出，得到提取液A；
S12，将假酸浆子取出后进行第二次浸泡，浸泡水量为350-450份，在40-50℃下浸泡10min，将甲酸浆子取出，得到提取液B；
S13，将提取液A、提取液B合并蒸发浓缩至200-250ml，得到改性剂；
S2，涤纶纤维的改性：
S21，按重量份计，称取40-60份涤纶纤维原料，对涤纶纤维经过除油剂除油，烘干；
S22，将由S21得到的涤纶纤维浸泡于25-40g/L氯化钙溶液中，捞出晾干；
S23，将由S22得到的涤纶纤维浸泡于改性剂中，浸泡时间为5-10min，捞出烘干，烘干温度为50-60℃，烘干时间4-6h，制备得到改性涤纶纤维。
通过采用上述技术方案，大豆蛋白纤维是由含有腈基、羟基的高聚物与大豆蛋白聚合并用湿法纺丝生产的再生蛋白质纤维，具有柔软、蓬松、保暖、吸水导湿性能好、光泽好、穿着舒适等优点。通过将改性涤纶纤维与大豆蛋白纤维共混制得无纺布，使无纺布的吸水性能提高，使无纺布在环境中保持一定的水分，使无纺布的抗静电性能提高。
假酸浆植株的种子名为假酸浆子，具有极高的药食两用价值。假酸浆子表面包裹有一层胶质，此胶质为可食用胶质，此胶质常作为一种食品（冰粉）的主要原料，假酸浆子中胶质的含量占总重的15-20％。假酸浆子胶是一种可形成凝胶的天然高分子，钙离子存在条件下可以改变胶分子的聚集状态。
改性剂中均匀分散有较高含量的假酸浆子胶，将涤纶纤维经过氯化钙溶液浸泡，在涤纶纤维表面附着一层钙离子。将附着有钙离子的涤纶纤维浸泡于改性剂中，改性剂内假酸浆子胶接触钙离子后，在涤纶纤维表面生成聚集一层凝胶层。假酸浆子胶凝胶具有较好的吸水性，且在干燥或通风环境下，凝胶内水分可蒸发干燥。
通过在涤纶纤维表面附着一层凝胶制得改性涤纶纤维，改性涤纶纤维具有较好的吸水性，且使无纺布的抗静电能力显著提高。同时凝胶具有较好的回弹性，使涤纶的回弹性提高，从而使无纺布的抗皱能力提高。
本无纺所用的材料为可降解材料，且部分降解后的材料可用于回收再利用，绿色环保。
可选的，所述涤纶纤维原料经过预处理，所述预处理的方法如下，将涤纶纤维原料经过紫外光辐照处理，辐照波长为270-290nm，辐照距离为4-6cm，辐照时间为2-3h。
通过采用上述技术方案，将涤纶纤维原料经过紫外辐照，涤纶纤维表面活性自由基团数量增多，凝胶中羟基、羧基能与涤纶纤维表面的活性自由基团建立氢键或化学键，使凝胶与涤纶纤维表面结合紧密，并提高涤纶纤维表层凝胶层的厚度，进而增强无纺布的吸水能力、抗静电能力、抗皱能力。
可选的，所述氯化钙溶液中包括3-5g/L的聚3，4-二氨基苯乙酸。
通过采用上述技术方案，聚二氨基苯常作为水处理的吸附材料，其对金属离子具有较好的吸附能力。通过在聚二氨基苯中引入羧基得到聚3，4-二氨基苯乙酸，使羧基与涤纶纤维表面容易形成化学键，进而使聚3，4-二氨基苯乙酸与涤纶纤维表面具有较好的结合力。聚3，4-二氨基苯乙酸对钙离子吸附性较好，使大量钙离子牢固吸附于涤纶纤维表面，假酸浆子胶遇钙离子后生成凝胶层更加致密、牢固地附着于涤纶纤维表面，提高凝胶的耐磨性，从而使无纺布经长时间使用后人具有较好的吸水性、抗静电性与抗皱性。
可选的，所述改性剂中添加有2-3份5-疏基吡啶-3-羧酸。
通过采用上述技术方案，5-疏基吡啶-3-羧酸中羧基，使其能与经过紫外光辐照的涤纶纤维表面结合能力增强，提高凝胶的附着能力。同时通过疏基的引入，使凝胶内部的疏基容易生成-S-S-，使凝胶结构网格化，使凝胶结构致密，从而提高凝胶层的耐磨性能。
可选的，所述聚3，4-二氨基苯乙酸的制备方法为：
将3，4-二氨基苯乙酸进行研磨，并按重量份称取3-4份3，4-二氨基苯乙酸粉末，加入0.3-0.6份聚乙二醇，继续研磨混合15-20min；加入0.2-0.4份过硫酸铵，继续研磨混合15-20min后再次加入0.2-0.4份过硫酸铵，继续研磨1-1.5h；研磨后放置于50-55℃中反应3-4h；取出依次用乙醚、乙醇、水进行冲洗，60-65℃下干燥36-48h，取出并研磨至平均粒径为30-50nm的纳米粒，得到纳米级聚3，4-二氨基苯乙酸。
通过采用上述技术方案，制备得到纳米级的聚3，4-二氨基苯乙酸，纳米级聚3，4-二氨基苯乙酸的比表面积较大，使其可吸附较多的钙离子，从而提高凝胶层的厚度。
可选的，所述改性涤纶纤维、大豆蛋白纤维的质量比为(7-8):(2-3）。
通过采用上述技术方案，通过上述配比使制备得到的无纺布具有较好吸水性、抗静电性能。
可选的，所述上胶所用胶水为丁腈胶乳。
通过采用上述技术方案，丁腈胶乳具有良好的耐油性、耐化学药品性、耐热性、粘接性和耐磨性，从而保证无纺布的粘结性能。
可选的，所述丁腈胶乳内水的质量分数为30-35%。
通过采用上述技术方案，水的含量较高，使丁腈胶乳的粘接性能较差。水的含量太低，使丁腈胶乳的流动性能差，使粘结不均匀。
综上所述，本申请具有以下有益效果：
1、通过将假酸浆子凝胶层包覆在涤纶纤维表面，使无纺布的吸水性能、抗静电性能提高。
2、通过在氯化钙溶液中添加聚3，4-二氨基苯乙酸，使假酸浆子凝胶层更加致密、牢固地附着于涤纶纤维表面。
3、通过添加5-疏基吡啶-3-羧酸，使凝胶结构网格化，使凝胶结构致密，从而提高凝胶层的耐磨性能。

对表1进行如下分析。
结合实施例3和实施例4-6并结合表1可以看出，涤纶纤维原料经过紫外辐照后，使无纺布的抗静电能力、抗皱能力增强。涤纶纤维紫外光辐照后，表面活性自由基团数量增多，凝胶中羟基、羧基能与涤纶纤维表面的活性自由基团建立氢键或化学键，使凝胶与涤纶纤维表面结合紧密，并提高涤纶纤维表层凝胶层的厚度，进而增强无纺布的抗静电能力、抗皱能力。
结合实施例6和实施例7并结合表1可以看出，通过在氯化钙溶液中添加聚3，4-二氨基苯乙酸，使无纺布的抗皱能力、抗静电能力和耐磨能力都有所提高。其中耐磨性能显著增加的原因是，聚3，4-二氨基苯乙酸对钙离子吸附性较好，使大量钙离子牢固吸附于涤纶纤维表面，假酸浆子胶遇钙离子后生成凝胶层更加致密、牢固地附着于涤纶纤维表面，提高凝胶的耐磨性，从而提高改性涤纶纤维的耐磨性，使改性涤纶纤维制备的无纺布的耐磨性能显著提高。抗静电性能增强的原因是，通过改变凝胶层结构，使其无纺布的表面电阻率下降，从而使抗静电能力提高。
结合实施例3和实施例8并结合表1可以看出，将5-疏基吡啶-3-羧酸添加至改性剂内，使凝胶层与涤纶纤维表面结合能力提高，同时在凝胶层内部引入疏基，通过疏基脱氢在凝胶层内部形成刚性化学键-S-S-，使凝胶层内部网格化，使凝胶层结构更加致密，刚性键-S-S-具有较好的耐磨性能，使无纺布的耐磨性能显著提高。
结合实施例3和对比例1并结合表1可以看出，通过在涤纶纤维表面附着一层由假酸浆子胶形成的凝胶制得改性涤纶纤维，改性涤纶纤维具有较好的吸水性，且使无纺布的抗静电能力显著提高。同时凝胶具有较好的回弹性，使涤纶的抗皱能力也显著提高。
本具体实施例仅仅是对本申请的解释，其并不是对本申请的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本申请的权利要求范围内都受到专利法的保护。
