Description
技术领域
本发明涉及一种马齿苋改性纤维的制备方法及应用。
背景技术
莱赛尔纤维是以天然纤维素为原料经溶剂纺丝方法生产的一种崭新的纯天然纤维。它有着棉的舒适性、涤纶的强度、真丝的柔软贴肤,因而广泛用于医疗器械、护肤领域的贴敷料和面贴膜产品中。市面上的莱赛尔纤维无纺布用于面贴膜时,必须加入羟乙基纤维素来增加面膜布的柔软性,使得产品配方有局限性。含有马齿苋纤维的无纺布,无需添加羟乙基纤维素就有较好的柔软性,且更为贴肤舒适。如果马齿苋纤维添加比例过大,则会影响面膜布的展开,在使用过程中也容易变形。
马齿苋具有清热解毒、凉血止血的功效。将马齿苋滤液融合到纤维里面对纤维进行改性,既能发挥再生纤维素纤维的特点,又能包含马齿苋提取物所具有的功能。马齿苋纤维制作过程中,如果马齿苋滤液添加过多会影响纤维的可纺性。
发明内容
本发明的目的是克服现有技术的缺陷,提供一种马齿苋改性纤维的制备方法及应用,马齿苋改性纤维可以检测到马齿苋中的活性成分,制成面膜布,柔软贴肤,敷在皮肤上可以起到抗炎舒缓的功效。
实现上述目的一种技术方案是:一种马齿苋改性纤维的制备方法,包括以下步骤:
S1,纤维前处理步骤:在25L的水桶中加入软化水和煮练剂,煮练剂与软化水形成浓度为40g/L的溶液,将水桶内的温度加热至70℃,搅拌15分钟;然后将纤维放入水桶中浸渍,浸渍浴比为1:20,浸渍时间为1h,浸渍完后,取出纤维,用60℃热水洗1次,再用冷水洗2次,然后将纤维脱水待用;
S2,纤维改性步骤:将马齿苋滤液倒入高压锅中,并在高压锅中加入软化水,搅拌10分钟,将经过步骤S1前处理后的纤维放入高压锅中,并搅拌均匀,然后将高压锅锅盖盖上,升温到130℃,保温2h;
S3,纤维后处理步骤:将经过步骤S2改性后的纤维水洗3次,然后做上油处理,上油处理的温度为75℃,时间为30min,然后将纤维在125℃的烘箱中烘干得到马齿苋改性纤维,所述马齿苋改性纤维的干断裂强度在2.4CN/dtex以上,湿断裂强度在1.25CN/dtex以上,干断裂伸长率为18%以上,抑菌率在95%以上。
上述的一种马齿苋改性纤维的制备方法,步骤S1中,所述水桶采用电加热保温桶。
上述的一种马齿苋改性纤维的制备方法,步骤S1中,所述纤维采用截面为梅花瓣形的莱赛尔纤维.
上述的一种马齿苋改性纤维的制备方法,步骤S1中,所述煮练剂为硼砂。
上述的一种马齿苋改性纤维的制备方法,步骤S2中,所述纤维与马齿苋滤液的质量比为3:7~1:1;
所述马齿苋滤液是马齿苋原料由醇/水混合液进行低温提取后,再用滤膜进行过滤后的澄清的酒红色滤液,其中所述醇/水混合液的重量为所述马齿苋原料的重量的3~16倍。
上述的一种马齿苋改性纤维的制备方法,步骤S3中,上油处理中用的试剂是滑爽柔软整理剂8156和抗静电剂丁酸酯磺酸钠。
本发明还提供了一种马齿苋改性纤维的应用,上述的制备方法制成的马齿苋改性纤维用于制备面膜布。
上述的一种马齿苋改性纤维的应用,按重量份计,将30~50份的马齿苋改性纤维与50~70份的莱赛尔纤维混纺制成面膜布。
采用本发明的马齿苋改性纤维的制备方法及应用的技术方案,得到的面膜布柔软贴肤,马齿苋活性成分含量高,湿敷于皮肤上具有抗炎舒缓的功效,与现有技术相比,有益效果体现在:
(1)马齿苋改性纤维应用于面贴膜或者贴敷料时,精华液中即使不添加羟乙基纤维素,马齿苋纤维面膜布也能柔软贴肤,同时又好展开且不易变形;面膜布中可以检测到马齿苋活性成分,敷于皮肤上具有抗炎舒缓的功效。
(2)马齿苋改性纤维的制备方法,首先通过将纤维煮练处理,然后将马齿苋滤液与煮练后的纤维高温高压处理,制得马齿苋改性纤维,这种方法中马齿苋提取物在被吸附过程中没有强酸强碱介入,马齿苋提取物中的有效成分不会被破坏,制得的纤维中马齿苋提取物含量高;
(3)采用浸渍和高温高压相结合的方式制备马齿苋改性纤维,马齿苋滤液添加量不受限制,大大提高了马齿苋滤液的添加用量,在提高用量的情况下,也不会对纤维产生破坏,大大降低了纤维的疵点,保证了纤维的强度;
(4)马齿苋滤液在纤维煮练后进行高温高压处理,能够使马齿苋滤液中有效成分充分地接触并渗透入纤维内部,马齿苋提取物在纤维内外附着均匀,渗透结合度高,提高了马齿苋提取物附着量,纤维处理地更均匀,质量更好;
(5)本发明的方法制备的马齿苋改性纤维具有较高的干断裂强度、湿断裂强度、干断裂伸长率,并且具有抗炎舒缓的效果;其中干断裂强度在2.4CN/dtex以上,湿断裂强度在1.25CN/dtex以上,干断裂伸长率为18%以上,抑菌率在95%以上。

本发明的马齿苋改性纤维的制备方法中,首先通过将纤维煮练处理,然后将马齿苋滤液与煮练后的纤维高温高压处理,制得马齿苋改性纤维,这种方法中马齿苋提取物在被吸附过程中没有强酸强碱介入,马齿苋提取物中的有效成分不会被破坏,制得的纤维中马齿苋提取物含量高;采用浸渍和高温高压相结合的方式制备马齿苋改性纤维,马齿苋滤液添加量不受限制,大大提高了马齿苋滤液的添加用量,在提高用量的情况下,也不会对纤维产生破坏,大大降低了纤维的疵点,保证了纤维的强度;马齿苋滤液在纤维煮练后进行高温高压处理,能够使马齿苋滤液中有效成分充分地接触并渗透入纤维内部,马齿苋提取物在纤维内外附着均匀,渗透结合度高,提高了马齿苋提取物附着量,纤维处理地更均匀,质量更好;最终得到的马齿苋改性纤维具有较高的干断裂强度、湿断裂强度、干断裂伸长率,并且具有抗炎舒缓的效果;其中干断裂强度在2.4CN/dtex以上,湿断裂强度在1.25CN/dtex以上,干断裂伸长率为18%以上,抑菌率在95%以上。
本发明的制备方法制成的马齿苋改性纤维,可以用于制备无纺布、面膜布。按重量份计,将30~50份的马齿苋改性纤维与50~70份的莱赛尔纤维混纺制成马齿苋纤维面膜布。
表4
按照表4的配方制备实施例6~10的马齿苋纤维面膜布。制备得到的面膜布的纤维缠绕规格,分布较为均匀,图1中显示了用电镜放大100倍拍摄的膜布表面图
面膜布感官测试:
请参阅图2,本试验由第三方招募12名感官评价员,组成评价小组。在脸部使用马齿苋纤维面膜布、市售天丝膜布1、市售天丝膜布2,评价使用前、使用后面膜布的感官属性,市售天丝膜布1、市售天丝膜布2均由莱赛尔纤维制成,三款面膜的精华液一样,只含有甘油、丁二醇、卡波姆、氨甲基丙醇,评价打分标准如表5所示:
表5
收集专家评价员的测试数据,统计问卷进行数据分析,结果如图2所示:
图1中展开难易程度、膜布形变容易程度对比图显示,马齿苋纤维面膜布要比市售的两款天丝面膜布表现稍好,面膜布的柔软性、贴合性对比图显示,马齿苋纤维面膜布的柔软性和贴合性要远远优于另外两款天丝面膜布。
面膜布功效测试:
请参阅图3,志愿者由于过敏性皮炎导致面部泛红发烫,用VISA拍摄了志愿者单次敷马齿苋面膜布10min前后的脸部图。用IPA的AOI工具在两侧脸部对称区域选择大小一致的红斑集中区域并计算a值,a值用于表征皮肤由于外界刺激导致的毛细血管扩张等而引起的皮肤发红。a值越小,皮肤红斑越少。如图2所示,使用本发明的马齿苋纤维面膜布后,a值显著减小,说明脸部红斑显著减少,表明马齿苋纤维面膜布有舒缓的功效。
综上所述,本发明的马齿苋改性纤维的制备方法及应用,得到的面膜布柔软贴肤,马齿苋活性成分含量高,湿敷于皮肤上具有抗炎舒缓的功效。
本技术领域中的普通技术人员应当认识到,以上的实施例仅是用来说明本发明,而并非用作为对本发明的限定,只要在本发明的实质精神范围内,对以上所述实施例的变化、变型都将落在本发明的权利要求书范围内。
