Description

一种安全防护手术衣
技术领域
本发明涉及一种手术衣，特别是指一种安全防护手术衣。
背景技术
手术衣是一种医用的屏蔽织物，通常用于阻隔医务人员与病人，阻止医务人员身上的病原体随汗液、皮屑等代谢产物扩散至手术区域，保护手术环境的无菌洁净。此外手术衣也承担着保护医务人员不受到病人体液所携带的具有强烈传染性的血载病毒如HBV(乙肝病毒)、HCV(丙肝病毒)、HIV(艾滋病毒)等病原体的危害，保护医务人员安全的功能。手术衣分为一次性手术衣和重复使用手术衣两类。一次性手术衣多采用无纺布为材料，用后即弃，可以有效避免再传染，但由于这类手术衣的大量遗弃，且其使用材料多数难以降解，对环境有极大危害，此类手术衣多数使用的材料在材料、结构上有一定的缺陷，其适用范围受到了一定的局限。而可重复使用的手术衣则在其阻隔性能上有着更高的要求，也对其持续抗菌和耐洗涤耐高温性能有了一定的要求。而目前常用的可重复使用手术衣多为棉布，其防水性能存在不足，对血浆等人体体液的阻隔性能不够好，使得这类手术衣的阻隔性能难以达到保护医务人员免受病原体危害的功能需求。
发明内容
本发明的主要目的在于提供一种高强度并具有优良抑菌性能的安全防护手术衣。
本发明采用如下的技术方案：
一种安全防护手术衣，由如下原料制备而成：聚酯切片、纳米氧化锌、PHMB抗菌整理剂、C6防水防油整理剂、925银导线；制备方法如下：
a、将纳米氧化锌粉末加入聚酯切片中共混、纺纱形成涤纶纤维；
b、将涤纶纤维与925银导线混纺，上机梭织成布；
c、用PHMB抗菌整理剂和C6防水防油整理剂对织成的布料进行织物后整理；
d、将布料裁剪成手术衣。
所述步骤a中，首先将纳米氧化锌粉末与聚酯切片熔融混合制成抗菌母粒，其中纳米氧化锌粉末的重量占比为30-40％；然后将制得的抗菌母粒与聚酯切片熔融混合纺纱制成涤纶纤维，其中抗菌母粒的重量占比为10％。
所述涤纶纤维的纱线密度为230T。
所述步骤b中，925银导线按照每1cm一支与涤纶纤维混纺成布，925银导线与涤纶纤维的重量配比为1：45。
所述步骤c包括如下子步骤：
c1、整理液配制：PHMB抗菌整理剂3g/L，C6防水防油整理剂25g/L，配制好后用冰醋酸调节整理液pH至5-6；
c2、浸轧：二浸二轧，浸泡浴比为1：10，浸泡至所有面料完全湿透后再浸泡30min，取出轧干，轧余率60-80％，重复浸泡和轧干的过程一次；
c3：将经过二浸二轧的涤纶面料于110℃下烘干，烘干后于单独的烘焙箱中150℃下烘焙5min。
还包括步骤e：将制成的手术衣浸泡于0.1wt％的水溶性壳聚糖水溶液中，浸泡30min，然后烘干。
与现有技术中的全棉手术衣和一次性手术衣相比，采用本发明的特殊方法制备的一种安全防护手术衣，具有优良的阻微生物穿透性、较低的落絮数、优良的抗渗水性、优良的强度和极佳的抑菌率。
具体实施方式
实施例一
本发明的一种安全防护手术衣，其制备方法如下：
a、首先将纳米氧化锌粉末与聚酯切片熔融混合制成抗菌母粒，其中纳米氧化锌粉末的重量占比为35％；然后将制得的抗菌母粒与聚酯切片熔融混合纺纱制成涤纶纤维，其中抗菌母粒的重量占比为10％，制得的涤纶纤维的纱线密度为230T。
b、925银导线按照每1cm一支与涤纶纤维混纺成布，925银导线与涤纶纤维的重量配比为1：45。
c1、整理液配制：PHMB抗菌整理剂3g/L，C6防水防油整理剂25g/L，配制好后用冰醋酸调节整理液pH至5.5；
c2、浸轧：二浸二轧，浸泡浴比为1：10，浸泡至所有面料完全湿透后再浸泡30min，取出轧干，轧余率70％，重复浸泡和轧干的过程一次；
c3：将经过二浸二轧的涤纶面料于110℃下烘干，烘干后于单独的烘焙箱中150℃下烘焙5min。
d、将布料裁剪成手术衣。
实施例二
本发明的一种安全防护手术衣，其制备方法如下：
a、首先将纳米氧化锌粉末与聚酯切片熔融混合制成抗菌母粒，其中纳米氧化锌粉末的重量占比为35％；然后将制得的抗菌母粒与聚酯切片熔融混合纺纱制成涤纶纤维，其中抗菌母粒的重量占比为10％，制得的涤纶纤维的纱线密度为230T。
b、925银导线按照每1cm一支与涤纶纤维混纺成布，925银导线与涤纶纤维的重量配比为1：45。
c1、整理液配制：PHMB抗菌整理剂3g/L，C6防水防油整理剂25g/L，配制好后用冰醋酸调节整理液pH至5.5；
c2、浸轧：二浸二轧，浸泡浴比为1：10，浸泡至所有面料完全湿透后再浸泡30min，取出轧干，轧余率70％，重复浸泡和轧干的过程一次；

d、将布料裁剪成手术衣。
e、将制成的手术衣浸泡于0.1wt％的水溶性壳聚糖水溶液中，浸泡30min，然后烘干。
将本发明的实施例一、实施例二与现有技术中常用的全棉手术衣和一次性手术衣进行对比试验，结果如表一：
表一
试验指标 全棉手术衣 一次性手术衣 实施例一 实施例二
阻微生物穿透性，湿态(IB) 4.5 3.5 5.6 5.8
落絮(计数) 8541 6857 1420 1156
抗渗水性(cm H2O) 42 75 103 110
干态涨破强度(kPa) 64 42 81 93
干态拉伸强度(N) 41 23 61 65
