Description

一种溶菌酶无纺布面料及其制备方法
技术领域
本发明属于非织造材料领域,具体涉及一种溶菌酶无纺布面料及其制备方法。
背景技术
溶菌酶是一种能水解致病菌中黏多糖的碱性酶。主要通过破坏细胞壁中的N-乙酰胞壁酸和N-乙酰氨基葡糖之间的β-1,4糖苷键,使细胞壁不溶性黏多糖分解成可溶性糖肽,导致细胞壁破裂内容物逸出而使细菌溶解。溶菌酶还可与带负电荷的病毒蛋白直接结合,与DNA、RNA、脱辅基蛋白形成复盐,使病毒失活。因此,该酶具有抗菌、消炎、抗病毒等作用。
近几年来,本领域的技术人员利用溶菌酶的特性,将其固定于纤维上,研制出具有抗菌性能的面料。例如刘贤明等将溶菌酶固定在人造纤维制成的HEPA空气过滤高效滤材上,从而制得生物杀菌滤材,并将其作为空调的空气净化系统,开发具有高效除尘和杀菌功能的产业用纺织品(刘贤明,马云骏.含溶菌酶的HEPA与双重杀菌过滤技术[J].家用电器科技,2001(2):20-21);胡英俊采用吸附法和戊二醛交联法将溶菌酶固定在羊毛织物上,从而赋予羊毛纤维优良的抗菌效果(胡英俊,范雪荣,王强等.溶菌酶在羊毛织物上的固定化[J].毛纺科技.2008(10):15)。
在纺织领域中,现有的溶菌酶固定技术主要应用于是单层纤维,同时将酶固定于纤维上的方法为低温4℃固定,而目前类似于纸尿裤等一次性无纺布产品面层多为复合纤维,在实际生产工艺中操作温度在130℃左右,溶菌酶在如此高温条件下极易失去活性,不适用于目前的无纺布生产工艺。
因此,如何利用溶菌酶天然安全、抗菌、消炎、抗病毒的优势,将其应用于纸尿裤等复合纤维上,是本技术领域技术人员急需克服的技术难关。
发明内容
本发明实施例提供一种溶菌酶无纺布面料的制备方法,旨在解决现有技术中的溶菌酶难以应用在纸尿裤等复合纤维上的问题。
本发明实施例是这样实现的,一种溶菌酶无纺布面料的制备方法,包括如下步骤:将刻有凹槽的印花辊筒浸渍亲水剂溶液,对第一面料层进行印亲水剂处理,得到亲水层;分别对所述亲水层及扩散层和渗水层分别进行开松、梳理、铺网、主梳理后,按照亲水层、扩散层和渗水层的顺序依次排列,置于热风箱,130~150℃下进行粘合固定,形成复合面层;待复合面层温度降至70~80℃时,将溶菌酶混合液喷洒于复合面层的亲水层上,经风干干燥,即得到溶菌酶无纺面料;其中,所述溶菌酶混合液按重量计包括如下组分:4.5%~6%溶菌酶、13.01%~23.1%酶稳定剂、5%~10%助吸附剂、5%~10%助干剂、0.5%~2%pH调节剂、其余为去离子水,酶混合液的pH值为5.0~6.0。
本发明实施例还提供一种溶菌酶无纺布面料,通过上述方法制得。
本发明实施例提供的溶菌酶无纺布面料的制备方法,当复合面层制备最终环节降温过程中,待温度降至70~80℃时,将溶菌酶液体通过喷涂的方式结合在复合面层表层,能更好的维持溶菌酶的热稳定性,降低溶菌酶的损耗,同时,本发明中的工艺的操作流程在实际生产工艺中可行性极高;相对于现有的在面层中添加抗菌剂主要为无机、有机和天然抗菌剂的方案对人体危害大的问题,,本发明的溶菌酶无纺布面料安全性强,无重金属存在及迁移风险,不刺激皮肤,同时具有优良的杀菌、消炎、抗病毒功效。
附图说明
图1是本发明实施例提供的溶菌酶无纺布面料的结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
本发明实施例提供的溶菌酶无纺布面料的制备方法,,包括如下步骤:将刻有凹槽的印花辊筒浸渍亲水剂溶液,对第一面料层进行印亲水剂处理,得到亲水层1;分别对所述亲水层1及扩散层2和渗水层3分别进行开松、梳理、铺网、主梳理后,按照亲水层1、扩散层2和渗水层3的顺序依次排列,置于热风箱,130~150℃下进行粘合固定,形成复合面层;待复合面层温度降至70~80℃时,将溶菌酶混合液4喷洒于复合面层的亲水层1上,经风干干燥,即得到溶菌酶无纺面料;其中,所述溶菌酶混合液4按重量计包括如下组分:4.5%~6%溶菌酶、13.01%~23.1%酶稳定剂、5%~10%助吸附剂、5%~10%助干剂、0.5%~2%pH调节剂、其余为去离子水,酶混合液的pH值为5.0~6.0。
本发明实施例提供的溶菌酶无纺布面料的制备方法,当复合面层制备最终环节降温过程中,待温度降至70~80℃时,将溶菌酶液体通过喷涂的方式结合在复合面层表层,能更好的维持溶菌酶的热稳定性,降低溶菌酶的损耗,同时,本发明中的工艺的操作流程在实际生产工艺中可行性极高;相对于现有的在面层中添加抗菌剂主要为无机、有机和天然抗菌剂的方案对人体危害大的问题,,本发明的溶菌酶无纺布面料安全性强,无重金属存在及迁移风险,不刺激皮肤,同时具有优良的杀菌、消炎、抗病毒功效。
在本发明实施例中,所述待复合面层温度降至70~80℃时,将溶菌酶混合液4喷洒于复合面层的亲水层1上,经风干干燥,即得到溶菌酶无纺面料的步骤,具体包括:待复合面层温度降至70~80℃时,将溶菌酶混合液4喷洒于复合面层的亲水层1上,喷涂量为8~10mL/m2,并对其进行风干干燥,风干温度为30~45℃,风干时间为5~10min,即得到溶菌酶无纺面料。
在本发明实施例中,亲水层1、扩散层2和渗水层3为双组份纤维PE/PP、PE/PET、PP/PP、CoPET/PET中的一种或几种混合体。
作为本发明的一种优选的实施例,亲水层1为PE/PP,纤维为纵向排列,纤维规格2.5D*40mm。
作为本发明的一种优选的实施例,扩散层2为PE/PP,纤维为杂乱排列,纤维规格1.5D*35mm。
作为本发明的一种优选的实施例,渗水层3为PE/PP,纤维为纵向排列,纤维规格4.5D*45mm。
作为本发明的一种优选的实施例,亲水剂为聚乙二醇甘油醚。聚乙二醇甘油醚中拒水的醚键与聚丙烯分子结合,聚乙二醇链段铺展在其表面,有效地提高了聚丙烯纺粘非织造布的表面能,使得水滴能够较好地在聚丙烯纺粘非织造布的表面铺展,有利于水滴的渗透。
在本发明实施例中,溶菌酶酶活为20,000,000U/g。溶菌酶是一种能水解致病菌中黏多糖的糖苷水解酶。主要通过破坏细胞壁中的N-乙酰胞壁酸和N-乙酰氨基葡糖之间的β-1,4糖苷键,使细胞壁不溶性黏多糖分解成可溶性糖肽,导致细胞壁破裂内容物逸出而使细菌溶解。溶菌酶还可与带负电荷的病毒蛋白直接结合,与DNA、RNA、脱辅基蛋白形成复盐,使病毒失活。因此,该酶具有抗菌、消炎、抗病毒等作用。溶菌酶是一种天然蛋白质,性质很稳定。溶菌酶在干燥室温环境下可以长期保存,纯品为白色或微白色结晶型或无定型粉末,无臭、味甜、易溶于水,不溶于乙醚、丙酮等,其化学性质非常稳定,在pH4~7范围内,100℃处理10min仍能保持原酶活性,在碱性环境中溶菌酶对热稳定性较差。
在本本发明实施例中,所述酶稳定剂为海藻糖、蔗糖、甘油、山梨醇、山梨酸、苯氧乙醇、硼砂、明胶中的五种或五种以上。
作为本发明一种优选的实施例,所述酶稳定剂为海藻糖、甘油、山梨醇、山梨酸、苯氧乙醇的组合。
海藻糖具有热稳定性和热激活特性。海藻糖在蛋白热变性过程中可维持蛋白的骨架,保持其天然结构。同时海藻糖是一种天然糖类,属于小分子保湿剂,与膜蛋白有很好的亲和性,可用作皮肤渗透剂增加皮肤对营养成分的吸收。增加细胞的水化功能,有良好的保湿性,在治疗由于皮肤干燥引起的皮屑增多、燥热、角质硬化有特效。甘油能够维持酶的天然分子构象,在一定程度维持酶的活性,提高酶的稳定性。山梨醇为无色针状结晶,或白色晶体粉末,无臭,有清凉甜味,易溶于水,难溶于有机溶剂,它耐酸,耐热性能好,与氨基酸,蛋白质等不易起美拉德反应。山梨酸能有效地抑制霉菌,酵母菌和好氧性细菌的活性,从而达到有效地延长食品的保存时间。山梨酸(钾)属酸性防腐剂,在接近中性(PH6.0-6.5)的食品中仍有较好的防腐作用。苯氧乙醇是一种经常用于护肤产品的有机化合物,是一种无色的油状液体,有抗菌功效。
本发明实施例中,含酶混合液中加入海藻糖、甘油、山梨醇、山梨酸、苯氧乙醇,在70~80℃条件下进行面层喷涂,不仅能够极好的维持溶菌酶的活性,附着在面层的海藻糖与甘油还能缓解肌肤燥热而引发的皮肤疾病。
在本发明实施例中,助吸附剂为聚丙二醇不同规格PPG-200、PPG-400、PPG-600、PPG-1000、PPG-1500中一种或两种的组合。
作为本发明一种优选的实施例,所述助吸附剂为聚丙二醇PPG400。PPG400溶于水,PPG400作为助吸附剂能够优先吸附到纤维上,再加上其自身含有羟基基团,能够与溶菌酶结合。采用喷洒的方式将混合酶液置于第一亲水层1(亲水剂处理后),PPG400更能有利于溶菌酶在面层的附着。在化妆品中,PPG400也常用作润肤剂、柔软剂、润滑剂。
本发明复合酶液中的PPG400与甘油涂喷于亲水层1,使得面料柔滑,同时在溶菌酶的共同作用下,本发明面料能够预防湿疹,防止红屁股发生。
作为本发明一种优选的实施例,所述助干剂为乙醇。待复合面层温度降至70~80℃时,将溶菌酶液体通过喷涂的方式,喷洒于复合面层的亲水层1,此过程中含酶混合液中的乙醇可以利用余温带走面层多余水分,随后低温风干干燥的过程中,可以缩短风干时间。
在本发明实施例中,所述pH调节剂为甘氨酸、柠檬酸、硼酸、苹果酸中一种或两种的混合物。
作为本发明一种优选的实施例,所述pH调节剂为柠檬酸。柠檬酸属于果酸的一种,可用于配制缓冲溶液,调节pH,可加快角质更新,常用于乳液、乳霜等。
甘氨酸是氨基酸系列20个成员中结构最简单的一个,又称氨基醋酸,为人体非必需的一种氨基酸,在分子中同时具有酸性和碱性官能团,在水溶液中为强电解质,通过水溶液酸碱性的调节可以使甘氨酸呈现不同的分子形态。
硼酸其水溶液呈弱酸性,可作为pH调节剂。
苹果酸存在于不成熟的苹果、葡萄、山楂等果实中,也可由延胡索酸经生物发酵制得,有特殊愉快、柔和的酸味,可以降低pH值,可清除皮肤表面皱纹,使皮肤变得嫩白、光洁而有弹性,具有抗菌和抗氧化的作用。
