Description
技术领域
本发明属于运动防护纺织品领域,具体涉及一种去体味可穿戴运动绷带的制备方法。
背景技术
狐臭即“腋臭”,是人体汗腺分泌物与皮肤在新陈代谢过程中产生的蛋白质、脂肪混合而成的短链脂肪酸物质与细菌作用而逸散的一种刺鼻气味。 在中国患有狐臭的人主要分布在南方和内蒙古以及新疆等地区。患有此病虽然不影响自身的生活,但是严重起来会导致周围人的排斥,以及自己内心的自卑。通常用除臭粉或喷雾的方法来掩盖狐臭,但这种方式效率低且没从根源去除狐臭,也有用涂胶封闭汗腺的方法,但是可能会引起人体不适,还有用手术开刀去除汗腺的方式来除狐臭,但是手术的风险和术后感染带来的问题非常严峻。由此有了研究本发明的想法,从腋臭产生的源头即排泄物中短链脂肪酸物质和细菌作用两个方面出发,开发设计去体味可穿戴的绷带。
因此,为消除狐臭人群的腋臭问题,设计制造出一种低成本,实用性强,低风险,无毒副作用和舒适性的防狐臭绷带产品迫在眉睫。
发明内容
本发明所要解决的技术问题是针对现有技术中存在的缺陷,提供一种去狐臭可穿戴运动绷带的制备方法,有效去除狐臭,止汗除臭,成本低廉。
为解决上述技术问题,本发明采用以下技术方案:
一种去狐臭可穿戴运动绷带的制备方法,步骤如下:
(1)将聚氨酯溶于四氢呋喃和N,N-二甲基甲酰胺共混溶剂中,在40~50℃下磁力搅拌至溶液均一、稳定的聚氨酯溶液,然后通过静电纺丝法制备20~100μm厚的聚氨酯纳米纤维膜即绷带基底;控制纳米纤维膜的形状,赋予绷带良好的弹性和可穿戴性;绷带基底的形状为“Y”、“T”、“U”状,且局部的形状和松紧性可调;
(2)将β-环糊精和二氧化硅溶于N,N-二甲基甲酰胺溶剂中,经超声1~2h和磁力搅拌至溶液均一、稳定,然后经静电喷涂在步骤(1)制得的聚氨酯纳米纤维膜上形成微球层得到复合膜;将纺丝液以静电喷涂的方式在聚氨酯基质上形成微球层,此微纳结构赋予复合膜具有特殊的表界面性质,能够用于特殊人群狐臭的防护。绷带可穿戴于身体,吸收人体排除汗液中的油脂类成分,起到隔离细菌与油脂类成分接触的效果。此微纳结构赋予复合膜特殊的表界面性质,能够用于特殊人群狐臭的防护。绷带微纳结构中,“铃”状β-环糊精具有独特的疏水空腔结构,能够吸收狐臭人群汗腺排出物中产生刺激性气味的油脂类成分,并将其包合,防止气味外泄;
(3)将硝酸银添加到氨水中,混合均匀后放入微波反应器中进行还原反应生成具有抗菌效果的纳米银颗粒溶液,反应完全后立即冷却至室温,将步骤(2)制备好的复合膜浸泡到纳米银颗粒溶液中2h后,从溶液中取出放到80℃烘箱中烘24h得到去狐臭可穿戴运动绷带,干燥后使纳米银颗粒负载到复合膜表面使膜具有抗菌性能,防止细菌消化分解汗液中的排泄物产生刺激性气体,达到消除狐臭的效果。
所述步骤(1)中聚氨酯分子量为33600,聚氨酯溶液的浓度为8~20wt%;所述共混溶剂中四氢呋喃和N,N-二甲基甲酰胺的质量比为1:1~1:8,优选1:1。
所述步骤(1)中纺丝温度为30~40℃,纺丝湿度为35~45%。
所述步骤(1)中静电纺丝加载电压为16~26kv,收集距离为15~22cm,射流速度为0.08~0.3ml/h。
所述步骤(2)中β-环糊精和N,N-二甲基甲酰胺的质量比为1:(4~5)。
所述步骤(2)中以β-环糊精的质量为基准,二氧化硅的添加量为2wt%,二氧化硅的直径为20nm。
所述步骤(2)中静电喷涂参数为加载电压为20~26kv,收集距离为16~24cm,射流速度为0.02~0.08ml/h。
所述步骤(3)中硝酸银的浓度为0.5~1wt%。
所述步骤(3)中微波反应器功率为300~600W。
本发明的有益效果:本发明利用静电纺丝和静电喷涂制备亲水疏油纳米纤维复合膜,将聚氨酯静电纺丝作为绷带基底,β-环糊精和二氧化硅经过配液-超声-搅拌-静电喷涂-干燥,在基底表面形成一层微球层,微米级β-环糊精和纳米级的的二氧化硅使复合膜表面具有微/纳级粗糙度和较高的孔隙率,且铃铛形的β-环糊精具有吸油封口的作用,可吸收人体汗腺排出的短链脂肪酸物质,防止其与细菌发生作用产生刺激性气味。进一步将纳米银颗粒负载到绷带上起到杀菌的效果,从根源上去除狐臭。本发明工艺简单,可操作性好,具有良好的应用前景。
