技术领域
本发明涉及手术衣技术领域,特别是一种高效防静电抗菌手术衣的生产加工方法。
背景技术
手术衣为医务人员在对病人手术时所穿的衣物,手术衣所用织物属于医疗用屏蔽织物,主要着重阻隔(barrier)性能。阻隔性能包括防止液体与微生物渗透的性能。医护人员在进行医疗救护中,不可避免地会接触到病人的血液与体液,病人的血液与体液往往可能携带HBV(肝炎B病毒)、HCV(肝炎C病毒)和HIV(艾滋病病毒)等各种病原体。其次,手术衣在穿着使用中还应该整洁干净,不易产生毛屑或微尘,因手术衣表面掉落的绒毛、微粒等容易携带病原体,对病人安全造成危害。此外,手术衣还应满足舒适性、抗菌、抗静电等其他要求。
现有的手术用手术衣,在使用时会产生局部静电现象,造成手术的不便,而且生产加工步骤复杂,造成加工成本上升。
发明内容
本发明的目的是为了解决上述问题,研发了一种高效防静电抗菌手术衣的生产加工方法。

S1、先制备无纺布层、加强层、防静电层和抗菌层的面料,其中无纺布层面料需进行收卷、烘干、三抗处理和成品收卷,然后将制备好加强层、防静电层和抗菌层的面料以及处理好的无纺布层的面料按照样板进行裁剪,得到裁剪好的样片;
S2、将裁剪好的四种样片按顺序安装在复合机上,利用复合机将四种样片复合,得到复合样板面料,在复合的过程中利用植物胶黏剂实现各层次之间的粘合;
S3、将复合样板面料缝合成型,先缝合手术衣主体上的衣领,然后将手术衣的长袖和主体缝合在一起,接着缝合手术衣的松紧袖口,最后对松紧袖口进行锁边处理;
S4、缝合手术衣的中腰部位,然后将左松紧调节带和又松紧调节带绱在腰部并进行松紧处理,避免抽片时出现死褶;
S5、将头罩缝合成型,然后手术衣和头罩成品进行浸渍、烘焙、杀菌、除静电处理,最终得到手术衣成品。
作为本发明的进一步说明,步骤S1中,所述无纺布层通过以下方法制成:
S11、将聚羟基丁酸酯结晶切片、干燥后,送入螺杆挤压机加热、熔融、挤压成聚羟基丁酸酯熔体,将聚乳酸以悬浮液的形式滴入所述聚羟基丁酸酯熔体内,搅拌混合后送入喷丝板喷丝、牵伸,得聚羟基丁酸酯/聚乳酸复合纤维,将所得复合纤维均匀铺放至网板上形成纤网,纤网经针刺机加固,得到第一基布层;
S12、将预定量的麻纤维和合成纤维按照间隔排列的方式放置于抓棉机中,经过抓棉、开松、去杂质处理后,充分混合得到混合纤维,然后将混合纤维加工成复合纤维网,将所述复合纤维网在高压水流的作用下,进行水刺加固处理,得到第二基布层;
S13、将第一基布层和第二基布层进行复合得到无纺布面料。
作为本发明的进一步说明,所述加强层由自羧甲基壳聚糖纤维、壳聚糖纤维或胶原纤维中的一种或者数种制成。
作为本发明的进一步说明,所述防静电层先通过涤纶长丝制成防静电基层,然后在防静电基层上均匀涂抹防静电剂。
作为本发明的进一步说明,所述抗菌层由竹炭纤维交织组合而成,经杀菌处理后在其表面均匀涂抹抗菌剂。
作为本发明的进一步说明,步骤S5中,对浸渍后的手术衣进行烘焙的温度为110℃。
作为本发明的进一步说明,步骤S5中,将烘焙后的手术衣放在密闭室内进行辐射硫化杀菌,辐射剂量为1400kGy。
作为本发明的进一步说明,所述加强层为网状结构,所述防静电层穿过加强层的网孔直接与所述无纺布层接触,所述抗菌层位于所述防静电层的外侧。
其有益效果在于,第一基布层由聚羟基丁酸酯与聚乳酸熔融、喷丝形成的复合纤维形成,使得复合纤维具有较强的可降解能力,和环保主题很贴合;第二基布层由麻纤维制成,能提供较好的舒适度和较强的力学性能,使手术衣不易损坏,抗菌层具有很好的抗菌性能,能将细菌阻隔在手术衣外部,防静电层具有很好的防静电性能,能够保证其在使用过程中不产生静电现象,防止空气中的灰尘粘附在手术衣上,具有很好的使用效果。
附图说明
图1是本发明所述的手术衣的剖面示意图。
图中,1、无纺布层;2、加强层;3、防静电层;4、抗菌层。
具体实施方式
首先说明一下本发明的设计初衷,现有的手术衣在穿着使用时易沾染毛屑或微尘,因手术衣表面掉落的绒毛、微粒等容易携带病原体,对病人安全造成危害,而且手术衣的抗菌性能也不高,无法满足医院的需求。
下面结合附图对本发明进行具体描述,如图1所示,一种高效防静电抗菌手术衣的生产加工方法,该手术衣从内而外依次包括无纺布层1、加强层2、防静电层3和抗菌层4,加强层2为网状结构,防静电层3穿过加强层2的网孔直接与无纺布层1接触,抗菌层4位于防静电层3的外侧,手术衣在生产加工时主要包括以下步骤:
S1、首先制备无纺布层、加强层、防静电层和抗菌层的面料,其中无纺布层面料需进行收卷、烘干、三抗处理和成品收卷,然后将制备好加强层、防静电层和抗菌层的面料以及处理好的无纺布层的面料按照样板进行裁剪,得到裁剪好的样片;
S2、将裁剪好的四种样片按顺序安装在复合机上,利用复合机将四种样片复合,得到复合样板面料,在复合的过程中利用植物胶黏剂实现各层次之间的粘合;
S3、将复合样板面料缝合成型,先缝合手术衣主体上的衣领,然后将手术衣的长袖和主体缝合在一起,接着缝合手术衣的松紧袖口,最后对松紧袖口进行锁边处理;
S4、缝合手术衣的中腰部位,然后将左松紧调节带和又松紧调节带绱在腰部并进行松紧处理,避免抽片时出现死褶;
S5、将头罩缝合成型,然后手术衣和头罩成品进行浸渍、烘焙、杀菌、除静电处理,最终得到手术衣成品,其中,对浸渍后的手术衣进行烘焙的温度为110℃,将烘焙后的手术衣放在密闭室内进行辐射硫化杀菌,辐射剂量为1400kGy。
上述步骤S1中,无纺布层的面料通过一下方法制成:
S11、将聚羟基丁酸酯结晶切片、干燥后,送入螺杆挤压机加热、熔融、挤压成聚羟基丁酸酯熔体,将聚乳酸以悬浮液的形式滴入所述聚羟基丁酸酯熔体内,搅拌混合后送入喷丝板喷丝、牵伸,得聚羟基丁酸酯/聚乳酸复合纤维,将所得复合纤维均匀铺放至网板上形成纤网,纤网经针刺机加固,得到第一基布层;
S12、将预定量的麻纤维和合成纤维按照间隔排列的方式放置于抓棉机中,经过抓棉、开松、去杂质处理后,充分混合得到混合纤维,然后将混合纤维加工成复合纤维网,将所述复合纤维网在高压水流的作用下,进行水刺加固处理,得到第二基布层;
S13、将第一基布层和第二基布层进行复合得到无纺布面料。
上述制备步骤中,第一基布层的几种原料都具有很强的降解性能,第二基布层具有很强的韧性,能加强手术衣的力学性能,不易损坏,能满足环保需求;其中加强层2由自羧甲基壳聚糖纤维、壳聚糖纤维或胶原纤维中的一种或者数种制成,因为这几种材料比较环保,而且具有很强的降解性能,因此使手术衣也具备了降解性能;抗菌层4由竹炭纤维交织组合而成,经杀菌处理后在其表面均匀涂抹抗菌剂,对病菌有很强的抗性;防静电层3先通过涤纶长丝制成防静电基层,然后在防静电基层上均匀涂抹防静电剂,能防止手术衣的外表面产生静电,防止空气中的细小颗粒受静电作用沾染上手术衣,减小手术时病人感染的风险,本发明提供的手术衣是一种多层复合结构,方法简单,能进一步减低手术衣的生产成本,与环保主题契合。
上述技术方案仅体现了本发明技术方案的优选技术方案,本技术领域的技术人员对其中某些部分所可能做出的一些变动均体现了本发明的原理,属于本发明的保护范围之内。
