Description
技术领域
本发明涉及无纺布材料技术领域，涉及一种具有抗菌、透气、耐用、防螨和消臭功效的聚烯烃无纺布及其制备方法。
背景技术
聚烯烃无纺布是一种强韧、耐用的聚烯烃材料，它比纸张更轻却更强韧，比织物性价比更高、且用途更广。聚烯烃无纺布材料具有独特的防水、透汽、防风和耐候性能，可实现透蒸汽但不透水，这有助于防止冷凝、湿气和空气渗入，其提供的可靠的水蒸汽透过性，可使围护结构内的潮气迅速派出，避免滋生冷凝水和霉菌。聚烯烃无纺布防护能够隔离细小粉尘，包括铅粉尘、石棉粉尘和霉菌粉尘等有害物质，为人们提供可靠有效的防护。同时，聚烯烃无纺布可以长久抵御紫外线和高低温的考验，持久耐用。但是，聚烯烃无纺布不具有抗菌防螨消臭的功效，且使用舒适性不佳。
而使纺织产品拥有抗菌、防螨和消臭的功能已经成为目前功能型纺织新产品的研究热点之一。功能型纺织产品的开发日益受到人们的重视，其市场需求量也越来越大。现在市场上的功能纺织产品主要是采用物理化学的方式进行后整理，来赋予纺织产品一定的特殊功能，比如，抗菌、防螨、防紫外、拒水、拒油等等，来吸引消费者针对某一方面的特殊需求。
随着近年来比较流行的一些疾病，如，严重急性呼吸道感染综合症（SARS）、猪流感和禽流感等，抗菌类的纺织产品越来越受到人们的关注和重视。这些传染病的发生都与病原微生物有关。这些致病菌对人体都会造成很大的伤害，甚至会夺去人们的生命。而抗菌类纺织品可以预防医院内的交叉感染和传染性疾病的传播，提高病人、老人、儿童的免疫能力；防止内衣裤和袜子上细菌的繁殖，从而阻止恶臭的产生；具有杀灭柠檬色青霉菌、结核杆菌和球毛壳菌、黑曲霉菌等各种霉菌，可以防止纤维材料变色、脆损以及纺织品贮藏时发生霉变，避免微生物对纺织品的侵蚀。
螨虫是一种节肢动物，体型微小，一般在0.1-0.5mm左右，人的肉眼无法看到。靠人体脱落的死皮及汗水、油脂为生。螨虫常滋生于枕头、床垫、被单、被套、被褥、沙发、席梦思、地毯、毛毯、长毛玩具、毛皮衣服、席子等处。有关资料显示，三个月不晒被子，600万螨虫陪你睡。螨虫的分泌物、代谢物是强烈的致敏源。会引起过敏性哮喘、过敏性鼻炎和过敏性皮炎等过敏性疾病，对儿童及过敏性人群的危害极大。同时，它能传播病毒、细菌，并可引起出血热、皮炎、毛囊炎、疥癣等多种疾病。
而纺织品上的异味会严重影响人的心情，会让人产生恶心、不舒服等生理反应。这些异味是人在生活中自身和周围环境中的微生物的各种作用和接触产生的。特别是在高温、潮湿或者人体剧烈运动后等情况下，人体代谢产生物质，如汗液，虽然汗液本身并没有臭味，但是与微生物作用，微生物快速繁殖，将汗液及其与皮脂、表皮屑混合物含有的尿素、高级脂肪酸、糖分、蛋白质等分解，从而产生大量的氨基物质等刺激性气味。
鉴于此，研究和开发出具有阻菌、透气、耐用、防护性能优良、抗菌、防螨和消臭功效，同时手感和服用性能优良的多功能产品不仅能够满足现代人们对纺织产品保健功能的要求，又能预防疾病，与人们倡导健康轻松的生活方式相吻合，具有十分重要的意义和广阔的应用前景。
发明内容
本发明为了克服上述现有聚烯烃无纺布的缺陷，提出一种具有抗菌、透气、耐用、防螨和消臭功效的且使用舒适的聚烯烃无纺布及其制备方法。
本发明提出的功能型防护聚烯烃无纺布的制备方法，包括以下步骤：
步骤1、采用氧冷等离子体对聚烯烃无纺布表面进行改性预处理，氧冷等离子体的输出功率为100-1000W，处理时间为1-60min；
步骤2、用抗菌整理工作液浸渍预处理后的聚烯烃无纺布，并加入质量浓度为30-90g/L的丙烯酸酯粘合剂，浸渍所述预处理后的聚烯烃无纺布的时间为0.5-1h；
其中，所述抗菌整理工作液是用超细氧化锌化合物、银离子抗菌剂、非离子柔软剂和水配制而成；
步骤3、将经抗菌整理工作液浸渍后的聚烯烃无纺布，送进轧车轧去所述聚烯烃无纺布中的液体，而使得所述聚烯烃无纺布的带液率为80-110%；接着利用热定型机，先在70-80℃温度下对所述聚烯烃无纺布烘干3-5min，后在105-110℃温度下对所述聚烯烃无纺布再烘干3-5min，控制所述聚烯烃无纺布出所述热定型机时的表面含潮率在5％以内，得到处理后的聚烯烃无纺布产品。
本发明还提供一种采用功能型民用防护聚烯烃无纺布的制备方法制备的聚烯烃无纺布。
本发明采用了特定的抗菌整理工作液和整理方法，利用本发明整理后的聚烯烃无纺布产品，既可实现对聚烯烃无纺布的抗菌防螨消臭和服用性的功能整理，又具有整理方法易于掌握、整理成本较低的特点。取得了很好的有益效果。经过检测，利用本发明整理后的聚烯烃无纺布产品，金黄色葡萄球细菌减少百分比为大于98.57％和大于99.98％。金黄色葡萄球细菌抑菌环为3mm和2mm。具有很好的杀菌抑菌效果。
本发明在聚烯烃无纺布具有阻菌、透气、耐用、防护性能优良等原有特性的基础上，再赋予其抗菌、防螨、消臭和优良服用性能等新的功效，结合聚烯烃无纺布原有特性，使聚烯烃无纺布产品以创新的角度应用于枕头、床垫、被单、被套、被褥、沙发、席梦思、地毯、毛毯、长毛玩具、毛皮衣服、席子等民用防护产品。
具体实施方式
下面结合实施例对本发明作进一步的详细说明，但并不作为对本发明做任何限制的依据。
本发明提供的一种功能型防护聚烯烃无纺布的制备方法，步骤如下：
步骤1、采用氧冷等离子体对聚烯烃无纺布表面进行改性预处理，氧冷等离子体的输出功率为100-1000W，处理时间为1-60min。
步骤2、用抗菌整理工作液浸渍预处理后的聚烯烃无纺布，并加入质量浓度为30-90g/L的丙烯酸酯粘合剂，浸渍所述预处理后的聚烯烃无纺布的时间为0.5-1h。
其中，所述抗菌整理工作液是用超细氧化锌化合物、银离子抗菌剂、非离子柔软剂和水配制而成。
步骤3、将经抗菌整理工作液浸渍后的聚烯烃无纺布，送进轧车轧去所述聚烯烃无纺布中的液体，而使得所述聚烯烃无纺布的带液率为80-110%；接着利用热定型机，先在70-80℃温度下对所述聚烯烃无纺布烘干3-5min，后在105-110℃温度下对所述聚烯烃无纺布再烘干3-5min，控制所述聚烯烃无纺布出所述热定型机时的表面含潮率在5％以内，得到处理后的功能型防护聚烯烃无纺布产品。
在优选实施例中，所述的聚烯烃无纺布可以选用杜邦™Tyvek®的聚烯烃无纺布。所述的抗菌整理工作液，可以按1L（约1000克） 水中投入超细氧化锌化合物5-10g、银离子抗菌剂3-5g和非离子柔软剂30-70g 的比列制备而成。根据不同的要求，抗菌整理工作液可以选取不同的配比：
其中，所述的超细氧化锌化合物可以优选日本佳友公司的ZE-100超细氧化锌化合物。所述的银离子抗菌剂可以优选德国巴斯夫公司的IRGAGUARD银离子抗菌剂。所述的非离子柔软剂可以优选德国巴斯夫公司的LUTENSOL TO非离子柔软剂。
所述的丙烯酸酯粘合剂可以优选美国DOW化学公司的EEA树脂。根据需要丙烯酸酯粘合剂加入到抗菌整理工作液的质量浓度可以为30g/L、60g/L、90g/L等。
根据所述功能型民用防护聚烯烃无纺布的制备方法，可以有效制得抗菌、防螨、消臭且服用性能优良的功能型民用防护聚烯烃无纺布产品。
本发明在聚烯烃无纺布具有阻菌、透气、耐用、防护性能优良等原有特性的基础上，再赋予其抗菌、防螨、消臭和优良服用性能等新的功效。经过检测，利用本发明整理后的聚烯烃无纺布产品，金黄色葡萄球细菌减少百分比为大于98.57％和大于99.98％。金黄色葡萄球细菌抑菌环为3mm和2mm。具有很好的杀菌抑菌效果。本发明使得聚烯烃无纺布产品以创新的角度应用于枕头、床垫、被单、被套、被褥、沙发、席梦思、地毯、毛毯、长毛玩具、毛皮衣服、席子等民用防护产品。本发明的方法工艺简单、无毒、无刺激、纤维强损小、成本低廉。
以上结合优选实施方式对本发明进行了具体描述，但是本技术领域内的技术人员可以对这些实施方式做出多种变更和变化，这些变更和变化应落入本发明保护的范围之内。
