Description
技术领域
本发明公开一种遇水凝胶型海藻纤维非织造布及其制备方法和应用,属于非织造布生产的技术领域。
背景技术
海藻纤维作为一种新型功能性纤维,是以海藻中提取海藻酸为原料,配成一定浓度的溶液,通过喷丝头挤压与凝固浴中的金属离子发生离子交换反应而形成的纤维。海藻纤维具有良好的吸水性、生物相容性、凝胶性、远红外效果、重金属吸附性等。
随着人们对面膜质量要求越来越高,而现有的面膜基布因加入大量精华液使其质地厚重、透气性差;又因仅是充当介质而造成资源的浪费。因此,人们都在寻找一种既能做介质,又能被肌肤吸收的面膜基布。海藻纤维与精华液中的钠离子发生离子交换反应形成水凝胶,增加面膜的保湿性;加之海藻纤维远红外效果,能促进面部皮肤血液供应、激活细胞新陈代谢;而且,海藻纤维的重金属吸附性能可吸收化妆品所残留的铅等重金属,起到清洁皮肤的作用;最后,海藻纤维可吸附皮肤中所含的铜离子,可使酪氨酸酶失活,从而可抑制酪氨酸产生黑色素,达到美白的效果。因此海藻纤维面膜基布不仅仅是充当介质,还能起到其他面膜基布未有的作用,与现今人们的护肤理念相迎合。具有极好的市场潜力。
市场上所流行的面膜通常以水刺非织造布为基布,公布号为CN 108179546 A的专利申请,一种海藻纤维无纺布及其生产工艺和应用所用高压非水溶剂液体流进行纤维缠结,应用于该方法加工非织造布的机器不方便加工其他无纺布,二是非水溶液中的离子会加速机器的表面的氧化性,造成机器使用周期缩短,且非织造布只能高吸湿,和传统的面膜一样无法产生凝胶。公布号为CN 109577003 A的专利申请,海藻纤维面膜基布及其制备方法,是将羧甲基纤维素纤维和海藻酸钙纤维混纺成非织造布后放入海藻酸钠溶液中改性,海藻纤维只能在稀溶液中保持纤维状,且海藻酸钠溶液粘度大,不利于改性操作,且此方法做出的水凝胶面膜粘连严重,脆性较大,不利于面膜包装。基于上述现有技术中的问题,本案由此产生。
发明内容
本发明的目的是提供一种遇水凝胶型海藻纤维非织造布及其制备方法和应用,该遇水凝胶型海藻纤维非织造布质感柔软且遇水凝胶,敷在皮肤上以达到补水美白的效果;加之该非织造布改变传统面膜基布只能做介质的局势,携带方便,易保存。
为达到上述目的,本发明所采用的技术方案为:
一种遇水凝胶型海藻纤维非织造布,其特征在于由以下原料制备而成:海藻纤维、骨架纤维、改性溶剂;
其中,海藻纤维与骨架纤维之间的质量比为30~80:20~70;
改性溶剂为氯化钠溶液与乙醇的混合溶液,且氯化钠溶液与乙醇之间的体积比为20~80:20~80,其中,氯化钠溶液的浓度为5%~20%;
或者,改性溶剂为乳酸钠溶液与乙醇的混合溶液,且乳酸钠溶液与乙醇之间的体积比为20~80:20~80,其中,乳酸钠溶液的浓度为5%~20%;
或者,改性溶剂为氯化钠溶液、乳酸钠溶液与乙醇的混合溶液,且氯化钠溶液和乳酸钠溶液的混合体与乙醇之间的体积比为20~80:20~80,其中,氯化钠溶液的浓度为5%~20%,乳酸钠溶液的浓度为5%~20%。
作为上述方案的进一步设置,所述骨架纤维为粘胶纤维、天丝纤维、莫代尔纤维、铜氨纤维中的一种或多种。
一种遇水凝胶型海藻纤维非织造布的制备方法,包括以下步骤:
(1)将质量比为30~80:20~70的海藻纤维与骨架纤维进行开松、梳理、铺网、水刺缠结形成非织造布;
(2)将非织造布置于改性溶剂内浸渍10~30分钟;
(3)将浸渍后的非织造布置于浓度在80%以上的乙醇溶液中进行洗涤,然后烘干,得成品。
所述烘干步骤的温度为50~90℃。
所述成品的含水量在15%以下。
本发明所制备出的遇水凝胶型海藻纤维非织造布,吸水性和保水性优良,且质感柔软。
本发明遇水凝胶型海藻纤维非织造布,不仅适合用作面膜布、眼膜布、手膜布、唇膜布等美容基布,也适合用作医疗基材,如用于制作敷料。
总之,与现有技术相比,本发明主要有以下有益效果:
(1)本发明遇水凝胶型海藻纤维非织造布遇水即发生凝胶,且凝胶效果好,可直接使用纯水使其凝胶,敷在脸上达到补水效果,因此也可达到减少精华液使用量的效果;
(2)本发明遇水凝胶型海藻纤维非织造布含水微量,易携带,易保存;
(3)本发明遇水凝胶型海藻纤维非织造布中的海藻纤维可吸附皮肤中的重金属离子,可起到清洁皮肤的作用,亦可吸附铜离子,可使酪氨酸酶失活,抑制黑色素的形成,具有一定的美白效果;
(4)本发明遇水凝胶型海藻纤维非织造布间不易发生粘连,且脆性较小,易于包装;
(5)本发明遇水凝胶型海藻纤维非织造布的制备方法,由于采用后道改性工艺,因此所使用的设备通用性强(可用于加工其他无纺布),且不会造成设备使用周期缩短的现象;同时本发明制备方法比公布号为CN 109577003 A的专利申请成本低,由于海藻酸钠溶液本身粘度比较大,操作比较困难,而本发明改性方法与之相比操作较简单。
以下结合具体实施方式对本发明作进一步说明。
具体实施方式
实施例1
(1)原料准备
本发明遇水凝胶型海藻纤维非织造布的原料为38mm×1.8dtex的海藻纤维、38mm×2.0dtex的天丝纤维和38mm×2.0dtex的莫代尔纤维,其质量比为30:40:30。将准备好的纤维进行开松、梳理、铺网、水刺缠结形成35g/m2的非织造布。
(2)浸渍
将准备好的非织造布在5%的氯化钠溶液和乙醇的体积比为50:50的混合溶液中浸渍30分钟。
(3)洗涤、烘干
将上道工序所制备的非织造布在90%乙醇溶液中洗涤,洗去纤维表面的杂质,然后于温度为90℃的条件下烘干,至含水率在15%以下,得成品。

经检测,上述实施例的检测结果如下:
实施例 | 1 | 2 | 3 | 4 | 5 | 6 |
凝胶情况 | 一般 | 一般 | 良好 | 良好 | 良好 | 良好 |
从结果可得出随着海藻纤维含量的增大,遇水凝胶效果越好;乙醇含量对凝胶效果的影响也很大,含量越低,凝胶效果越好。
上述实施例仅用于解释说明本发明的发明构思,而非对本发明权利保护的限定,凡利用此构思对本发明进行非实质性的改动,均应落入本发明的保护范围。
