Abstract
本发明公开了医疗卫生材料用强拉力无菌纺粘无纺布的生产方法,通过将改性聚酯溶解在碱性条件下,加入阻燃剂,使得改性聚酯上的氨基与阻燃剂上的环氧基反应,将阻燃剂接枝在改性聚酯上,再熔融挤出,纺丝成网,热轧加固,制得预处理无纺布,将预处理无纺布用多巴胺溶液处理,使得无纺布表面附着负电荷,再用带有正电荷壳聚糖溶液浸泡,使得壳聚糖通过静电作用吸附在无纺布表面,形成壳聚糖层,再用带有负电荷的氧化石墨烯分散液浸泡,使得壳聚糖层表面附着石墨烯层,进而使得纺粘无纺布具有抗菌效果,同时具有一定的阻燃效果,避免了遇到火星时无纺布出现燃烧现象。
Description
技术领域
本发明涉及医疗用品制备技术领域,具体涉及医疗卫生材料用强拉力无菌纺粘无纺布的生产方法。
背景技术
无纺布又称不织布,是由定向的或随机的纤维而构成,因具有布的外观和某些性能而称其为布。无纺布没有经纬线,剪裁和缝纫都非常方便,而且质轻容易定型,深受手工爱好者的喜爱。无纺布制品因色彩丰富、鲜艳明丽、时尚环保、用途广泛、美观大方,图案和款式都多样,且质轻、环保、可循环再用,被国际公认为保护地球生态的环保产品。广泛应用于化工、汽车工业、家居建材、生活装饰、医疗卫生等等领域,纺粘无纺布:将聚合物挤出、拉伸,形成连续长丝后,长丝铺设成网,纤网再经过自身粘合、热粘合、化学粘合或机械加固方法,使纤网变成无纺布。
现阶段纺粘无纺布的原料多为丙纶和涤纶,使得制备出的无纺布机械性能一般,且遇到火星或烟灰会出现孔洞,严重的甚至会出现燃烧。
发明内容
本发明的目的在于提供一种医疗卫生材料用强拉力无菌纺粘无纺布的生产方法,解决了现阶段纺粘无纺布机械强度差且抗菌效果一般的问题。
本发明的目的可以通过以下技术方案实现:
一种医疗卫生材料用强拉力无菌纺粘无纺布的生产方法,具体包括如下步骤:
步骤S1:将改性聚酯溶于氯仿中,调节混合pH值为碱性,加入阻燃剂,在转速为150-200r/min,温度为40-50℃的条件下,进行反应5-7h后,蒸馏出溶剂,将底物熔融挤出,纺丝成网,热轧加固,制得预处理无纺布;
步骤S2:将预处理无纺布浸泡在乙醇中,在频率为30-40kHz的条件下,超声处理30-40min后,用去离子水洗净并烘干,再浸泡在多巴胺溶液中,在温度为25-30℃的条件下,浸泡20-25h后,取出浸泡在壳聚糖溶液中,浸泡20-30min,取出浸泡在氧化石墨烯分散液中,浸泡20-30min,取出比用去离子水洗净,烘干制得强拉力无菌纺粘无纺布。
进一步,步骤S1所述的改性聚酯中氨基与阻燃剂中环氧基的摩尔比为1:2。
进一步,步骤S2所述的多巴胺溶液的质量分数为0.2-0.5%,壳聚糖溶液的质量分数为3-5%,氧化石墨烯分散液的质量分数为0.6-1%。
进一步,所述的改性聚酯由如下步骤制成:
