Description

一种高吸水高透气医用磁疗弹性无纺布
技术领域
本发明属于医用无纺布生产技术领域，具体涉及一种高吸水高透气医用磁疗弹性无纺布。
背景技术
医用无纺布是一种不需要纺纱织布而成的织物，主要是直接通过物理的方法粘合在一起，所以当粘成时会发现无法从无纺布中抽出线头。它突破了传统的纺织原理，与传统的纯棉机织纺织品相比，医用无纺布具有防潮、透气、柔韧、质轻、不助燃、容易分解、无毒无刺激性、价格低廉、可循环再利用等优势，非常适用于医学领域。医用无纺布的应用十分广泛，在医学上可以用于生产口罩、手术帽、一次性手术衣、一次性医用床单、产妇包、尿布等等，将医用无纺布放置于室外，最长寿命只有90天，如果是放在室内，在8年内就会自然分解，所以属于新型环保材料。
日前，磁疗功能性纤维材料的研究与应用技术正日趋成熟，磁性功能纺织品必将发展成为人们日常生活中必不可少的产品。但磁性功能纺织品还存在不完善的地方和亟待解决的问题，例如，在对产品磁通量的测量上，还未形成统一的评价方法与标准；又如，磁性材料在纤维及面料中的分散不均匀性、磁疗功能保健纺织产品的舒适性较差以及应用品种较少等。
发明内容
本发明的目的是针对现有的问题，提供了一种高吸水高透气医用磁疗弹性无纺布。
本发明通过以下技术方案实现：
一种高吸水高透气医用磁疗弹性无纺布，包含有以下的组分：改性聚乳酸纤维20~27份、改性竹纤维20~33份、羟甲基纤维素10~20份、干酪素2~5份、大豆蛋白纤维20~30份、海藻酸钠5~10份、淀粉20~35份、磁性淀粉20~23份、改性聚丙烯酰胺纤维40~45份、植物提取物3~5份。
一种高吸水高透气医用磁疗弹性无纺布，其制备方法包括以下步骤：（1）称量各种原材料备用；（2）将改性聚乳酸纤维、改性竹纤维、羟甲基纤维素、干酪素、大豆蛋白纤维、海藻酸钠淀粉、磁性淀粉、改性聚丙烯酰胺进行共混，混合为一种高弹、磁性、吸水、湿强高的纤维素纤维；（3）将混合好的多功能纤维素纤维进行精开松，梳理并杂乱形成无纺布纤维网；（4）对全交叉折叠的纤维棉网进行水刺预刺预湿，所用水针的针板规格为0.7~1.2mm高密度锯牙型水针板，预湿圆鼓的衬网为开孔率14%的锥形网，初加工成有一定强度克重均匀的水刺无纺布纤网；（5）将预湿后的无纺布纤维网进行360度全维度水刺固结，共7道水刺工序，水刺压力成螺旋式梯度逐步增加；在水剌工序的最后一道通过高压水刺打孔技术，形成每平方厘米无纺布布面同时成形时平均分布30个水流孔；（6）将植物抗菌剂溶解在100℃的纯净水中，并保证溶液的水温处于60~80℃，同时将完全固结好的水刺无纺布进行水浴法加工，使无纺布匀速工作，均匀吸附溶液中的植物功能药体；（7）对完成水刺和吸附的功能性无纺布进行烘干加温，第一步是圆筒烘干，对布面进行表层干燥，干燥的温度从50~110℃按梯度升温；第二步是梯式穿透干燥工艺，达到植物抗菌成分对纤维从表层到纤维内芯的逆萃取效果；第三步旋转式圆筒烘燥，干燥温度从高温逐步降低。
进一步的，所述磁性淀粉采用水热法制备得到，具体过程为，首先用甲基丙烯酸缩水甘油酯对淀粉进行改性使其带有双键官能团，然后将其与丙烯酸、N，N-二甲基丙烯酰胺、六水合三氯化铁、柠檬酸三钠、无水乙酸钠加入反应器中，再加入聚乙二醇，加热到80℃的情况下磁力搅拌至浆液呈亮黄色，将溶液转移至聚四氟乙烯内衬的反应釜中，放入烘箱中200℃下反应24h小时以上，待冷却至室温后，乙醇、水分别洗涤三次，40℃下，磁性分离后，加入过氧化苯甲酰作为引发剂，在紫外光照作用下反应后，即得。
进一步的，所述的改性聚丙烯酰胺纤维为为淀粉接枝聚丙烯酸-聚丙烯酰胺共聚物，具体制备方法为：将50~60份淀粉在水中糊化后，再将200份正己烷与0.2~0.5份表面活性剂混合均匀，接着将20~23份丙烯酸、100~130份丙烯酰胺、20~23份三羟甲基丙烷三丙烯酸酯、0.05~0.5份过硫酸铵和0.1~0.5份N,N,N',N'-四甲基乙二胺混合水溶液在搅拌下加入到油相溶液中，混合一定时间后，可形成油包水体系，用氨水将乳液的pH值调制到中性后进行反应，再经过滤、真空干燥后，经纺丝机纺丝，冷却定型，裁切，即得。
进一步的，，所述的改性竹纤维为硫酸盐竹浆经过臭氧和双氧水同时处理并辅以超声波处理30min；所述臭氧气体浓度为1~2ppm，所述双氧水浓度为双氧水浓度为10~20%。
进一步的，，所述的植物提取物为灯笼果、鼠尾草、茶渣、芦荟、艾蒿、石榴皮、黄柏、栀子、蓍草、甘草、黄连、大黄、蒲公英、车前子、金银花、连翘、鱼腥草中的一种或多种的提取物。
进一步的，所述的改性聚乳酸纤维为为NCO/OH摩尔比为1：1.05的二苯基甲烷二异氰酸酯、六亚甲基二异氰酸酯和聚己内酯二元醇在超声10kHz条件下加入总重0.08~0.1%分数的辛酸亚锡，在55℃下搅拌反应24h，经纺丝机纺丝，冷却干燥，即得。
本发明的有益效果：
网络之间相互缠结，增加了网络密度，提高了分子链间的相容性，两种性能差异很大或具有不同功能的聚合物可以通过网络形成稳定的结合，使相组织微细化并提高了相间结合力。由于网络互锁的环连结构，在相分离上与化学共聚物及机械掺混体不同，在增加网络密度、提高高分子链相容性及增大相间结合力等方面存在动力学强迫互容行为，使得两组分的相容性显著改善，同时还具有细胞状结构、双相连续和界面互穿等特有的形态。
利用淀粉可进行阳离子交换的基团,使亚铁离子与其发生交换然后再经过水解和氧化,转化为具有磁性的四氧化三铁而沉积在淀粉的无定形区中。所生成的磁性物质(微粒)在纤维中所处位置受制于原来纤维中进行阳离子交换基团的位置。
共聚单体既含有氨基又含有羧基便可以省去皂化反应步骤，通过改变不同单体间比例可以控制淀粉接枝共聚物的侧链结构和组成，最终可以达到调控树脂吸水性能的目的。
磁性纤维制品因磁性微粒的N极与S极在纤维内的无序排列和在织造过程中纤维交织导致N极、S极的重叠和减小而磁性大小不一致。某一部分磁性叠加增强，另一部分减小削弱，另外，磁力线网膜疏密还随衣着的平展和折皱而变化，这些动态的变化引起磁性大小的改变正好起到交变的理疗刺激紧靠织物纤维边缘无数磁性微粒产生的许多N极、S极磁回路及发射出去的磁力线。交织成一层看不见的立体磁力线网。这种网膜能对贴近的肌肤进行全方位的立体刺激和按摩，使肌肤表面处于微运动状态，激活细胞代谢能力，促进身体微循环。与肌肤穴位素贴的磁微粒发出的磁力线可以穿透人体的某些穴位。人体在磁场作用下，通过神经体液系统，发生电荷、电位、分子结构、生化性能和生理功能方面的变化，从而提高机体的调节能力和抗病能力，有利于病理过程向正常方向转化，促使疾病好转或痊愈善。
本发明相比现有技术具有以下优点：
首先，本发明公开的一种高吸水高透气医用磁疗弹性无纺布是一种理想的医用卫生材料。它具水刺无纺布应有适当的强度、柔软性、良好的吸湿透气性水刺无纺布和血水扩散性，能有效地抵抗细菌穿透和液体污染，并能够有效地控制污染途径，避免交叉感染，减少尘屑毛羽的脱落、净化手术环境、使用方便、便于贮存，而这些优点正是传统的棉纺织物和粘胶纺织卫生材料所不及的。可以制成急救包、伤口敷布、开刀巾、绷带、橡皮、脱脂棉等。
将生物链淀粉分散在纤维素纤维内得到的复合纤维，属于生态纤维，有包覆功能，分子内可包覆其他物质，可用于除去臭味物质或有害物质。因为黏胶内的生物链淀粉在纤维中起分子袋的作用，有时此分子袋包覆目标物质，有时分子袋内的物质逐渐排出。有消臭功能，在生物链淀粉形成的分子袋内封闭臭味物质，从而发挥消臭功能，对低分子的氨、醋酸臭和有烷基链的老龄臭都有效果；具有抗菌、抗病毒功能，对皮肤的刺激性小，具有生物可降解性。质轻，具蓬松性，手感好；柔软：成品柔软度适中，具舒适感；拨水、透气：聚丙烯切片不吸水，含水率零，成品拨水性佳，由100%纤维组成具多孔性，透气性佳，易保持布面干爽、易洗涤；无毒、无刺激性；产品采用符合FDA食品级原料生产，不含其他化学成分，性能稳定，无毒、无异味，不刺激皮肤；抗菌、抗化学药剂：聚丙烯属化学钝性物质，不虫蛀，并能隔离存在液体内细菌及虫类的侵蚀；抗菌、碱腐蚀、成品不因侵蚀而影响强度。
未添加任何人工合成抗菌剂，本身带有磁性，磁场可以调节体内生物磁场、产生感应微电流、改变细胞膜通透性、改变某些酶的活性和扩张血管、加速血流，从而达到如止痛、消肿等辅助治疗作用。
