Description
技术领域
本发明涉及一种原液着色耐氯漂手术衣面料的制备方法,属于医用纺织品材料技术领域。
背景技术
可重复性使用手术衣,对面料的要求极为苛刻。首先要有良好的透湿性、无落絮、防静电,以保证穿着的舒适性,最关键干湿态下的阻隔性能要十分优异,能有效阻隔液体、各种微生物以及微尘颗粒物的穿透。特殊手术场合,如大量液体暴露,高喷射及溅射风险,对手术衣产生的压力很高,还须具备一定吸附功能及耐水压性能。可重复性使用又对面料强度韧性、耐洗涤剂、耐杀菌消毒剂方面提出很高要求。单一材质难以达到上述要求,目前基于特殊功能薄膜的多层复合面料最具发展前景,其中以PTFE微孔膜复合两层聚酯长丝纤维布所能达到的综合性能最为优异。但是PTFE膜表面润湿性能比较差,与聚酯纤维布贴胶复合后存在剥离强力低、不耐反复洗涤的问题,增加用胶量虽能提高剥离强度,但会大幅降低面料的透湿性能。
发明内容
针对现有技术存在不足,本发明提供一种原液着色耐氯漂手术衣面料的制备方法,实现以下发明目的:
提高聚酯纤维布层与PTFE膜的剥离强力;
提高面料的耐洗涤性。
为实现上述发明目的,本发明采取以下技术方案:
一种原液着色耐氯漂手术衣面料的制备方法,其特征在于:包括面料的选材、改性PTFE膜的制备、纤维布与改性PTFE膜胶粘复合;所述改性PTFE膜的制备,包括浸渍液的制备和紫外光处理。
以下是对上述技术方案的进一步改进:
步骤(1)面料的选材
上层:由第一经纱、第二经纱和纬纱三种纱线组成,径向第一经纱平行紧密排列,纬向上每隔10毫米宽度插入一根与第一经纱平行的第二经纱,径向上每隔0.8毫米织两根纬纱;
所述第一经纱是绿色原液着色聚酯长丝色纱DTY 75D/72F半光轻网;
所述第二经纱是DTY 75D/36F黑色半光长丝和锦纶基20D/3F黑色导电丝加捻形成的,捻向:Z捻,捻度:450捻/米;
所述纬纱是绿色原液着色聚酯长丝色纱DTY 75D/72F半光轻网。
中间层:改性PTFE膜,克重18~20g/m2,热稳定性190~210℃,厚度48~50um,静水压200~220KPa,透湿率6850~7000g/m2·d。
下层为聚酯长丝纬编针织面料;
所述针织面料为DTY 50D/36F纬平针组织;
所述针织面料的克重为65g/m2。
步骤(2)改性PTFE膜的制备
1、浸渍液的制备:
1)预分散纳米二氧化钛水溶液的制备
脂肪胺聚氧乙烯醚加入水中,搅拌溶解后,搅拌速率6000~10000转/分条件下,缓慢加入纳米二氧化钛粉末,加料完毕后,搅拌10分钟,停止搅拌后再超声分散20~40分钟后得到预分散纳米二氧化钛水溶液;
所述纳米二氧化钛粉末为金红石型亲水性粉末,粒径分布10~30nm,纯度99%;
所述预分散纳米二氧化钛水溶液,二氧化钛的质量浓度为25%,脂肪胺聚氧乙烯醚的质量含量为0.5~1%。
2)双氧水-离子液体混合液的制备
1-丁基-3-甲基咪唑三氟甲烷硫酸盐、1-丁基3-甲基咪唑对甲基苯磺酸盐按质量比1:1混合,再加入双氧水搅拌混合,得到过氧化氢质量浓度15~25%的混合液;
所述双氧水中过氧化氢的质量浓度为50%。
3)制得浸渍液
预分散纳米二氧化钛水溶液与双氧水-离子液体混合液按质量比1:1混合后,6000~10000转/分速率下强力搅拌20~40分钟后超声分散35分钟,使溶液达到澄清透明状态,得到浸渍液。
2、紫外光处理
将预先除油清洗洁净的PTFE膜浸入浸渍液中,紫外光照射1~2.5小时后取出,用去离子水反复冲洗后80℃烘干,得到改性PTFE膜;
所述紫外光照射,选用紫外光高压汞灯,功率500W,波长365nm,光源距PTFE膜的距离固定为10厘米。
步骤(3)纤维布与改性PTFE膜胶粘复合:
液体热熔胶均匀涂覆在改性PTFE膜的上下两面,贴合好上层和下层面料后,热压复合后可得到手术衣面料成品;
所述液体热熔胶为反应型聚氨酯热熔胶,AP-J7738通用型;
所述均匀涂覆,改性PTFE膜的上下两面胶量一致,总上胶量控制在11~17g/ m2;
