Description

一种纯蚕丝尿不湿及其制备方法
技术领域
本发明涉及婴幼儿用品技术领域,具体涉及一种纯蚕丝尿不湿及其制备方法。
背景技术
尿不湿是婴幼儿常用的护理用品之一,现有的尿不湿通常由三层层状结构组成,底层为具有防水功能的塑料薄膜,防止水分向外渗透,起到了良好的隔水作用,中间夹层为具有优异的吸水和蓄水量的吸水性材料,表层为无纺布。
而现有的无纺布表层大多采用合成纤维制成,合成纤维吸湿性较差,长时间使用容易造成婴幼儿皮肤瘙痒、红屁股等症状,而且无纺布表层柔软性较差、表面较为粗糙,直接与婴幼儿娇嫩的皮肤接触会产生摩擦,容易对婴幼儿的皮肤造成损伤,引起婴幼儿不适,甚至导致婴幼儿皮肤过敏;此外,由于尿不湿吸收婴幼儿尿液,容易滋生细菌,而尿不湿与婴幼儿的生殖系统直接接触,这样就导致婴幼儿的生殖系统特别容易受到细菌的侵袭,容易发生感染。
因此,需要研发出一种柔软舒适、干爽透气、对皮肤无刺激、无过敏反应且具有自净抗菌作用的尿不湿来满足婴幼儿的日常需要。
发明内容
为了解决上述背景技术中存在的问题,本发明的目的在于提供一种纯蚕丝尿不湿,其亲肤性好、对皮肤无刺激、无过敏反应、抗菌消炎,使用时柔软舒适、干爽透气。此外,本发明还提供一种纯蚕丝尿不湿的制备方法。
为了实现上述目的,本发明采用以下技术方案:
本发明的第一方面,提供一种纯蚕丝尿不湿,从上至下依次包括面层、吸湿层和底层,所述面层内表面附着有内表接触层,所述内表接触层为蚕丝层,所述蚕丝层由天然蚕丝纤维纺织而成,所述面层由质量百分比为30-60%的天然蚕丝纤维和40-70%的植物纤维制成,所述植物纤维为麻纤维、棉绒纤维和竹炭纤维的混合物,所述底层为不可透过液体的热塑性合成树脂薄膜。
内表接触层由于与婴幼儿的生殖系统直接接触,采用天然蚕丝纤维纺织而成蚕丝层,由于蚕丝中含有丰富的丝素、丝胶蛋白,与皮肤具有较强的亲和力,对皮肤无刺激、无过敏反应且渗透力强,保持干爽,还能保持水分平衡,提高使用舒适度。面层通过天然蚕丝纤维和植物纤维混纺而成,柔软贴身、丝滑透气、绿色健康,其与婴幼儿皮肤贴合时,可对婴幼儿皮肤进行保护,减少摩擦力,防止发生皮肤过敏或者引起婴幼儿不适,此外,通过加入植物纤维能在保证品质的基础上,降低了产品成本,增加了市场竞争力。
优选地,所述吸湿层包括从上至下依次设置的第一吸湿层和第二吸湿层,所述第一吸湿层内设置有柔性吸水块,所述第二吸湿层内设置有自由分布的高吸水性树脂颗粒,所述第一吸湿层与所述面层之间设置有隔离层,所述隔离层为速干鸟眼布的单向导湿的无纺布。
第二吸湿层选用高吸水性树脂颗粒,能够吸收自身重量几百倍至几千倍的水分,无毒、无害、无污染,且高吸水性树脂颗粒能够根据挤压情况自由移动和变形,对皮肤无压迫感;第一吸湿层位于第二吸湿层的上方,第一吸湿层中的柔性吸水块能够吸收多余的或由第二吸湿层因挤压渗透处的液体,且柔性吸水块柔性可形变,保证整体的舒适度。通过设置隔离层,使得渗入至吸湿层中的液体无法渗出来。
优选地,所述无纺布面料包括以下质量份的组分:粘胶纤维30-50份、铜氨纤维10-20份、涤纶纤维10-20份、竹炭纤维15-30份、马齿苋1-5份、黄芩1-5份、蒲公英3-8份。
以粘胶纤维、铜氨纤维、涤纶纤维、竹炭纤维作为主要成本制备无纺布,具有良好的透气性、透水性,加入马齿苋、黄芩和蒲公英作为抗菌成分,大大提高了无纺布的自净杀菌性能。
优选地,所述植物纤维中麻纤维、棉绒纤维和竹炭纤维的质量比为:(1-3):(4-6):(1-2)。
优选地,所述吸湿层和所述底层之间还设置有透气防渗层,所述透气防渗层为一层PET打孔膜,所述PET打孔膜有孔一侧朝向所述吸湿层设置,且所述PET打孔膜的孔型呈漏斗型。
通过在吸湿层下方设置透气防渗透层,储存在吸湿层中的水分不会直接接触面层,在外力挤压作用下水分不易向外渗透,反渗透性能较好。
本发明的第二方面,提供一种上述纯蚕丝尿不湿的制备方法,包括以下步骤:
S1、天然蚕丝纤维的制备:将蚕茧放入含有5-15wt%冰醋酸和0.5-3wt%氯化钙的水溶液中浸泡40-60min,浸泡温度为30-50℃,然后再进行水洗、中和处理至pH呈中性,在30-40℃条件下烘干至含水量为10-20%,即可制得含胶量在50-70%的天然蚕丝纤维;
S2、内表接触层的制备:将步骤S1中制得的天然蚕丝纤维在120-150℃下熔融,经过滤、纺丝、牵伸、成网、热轧定型即得;
S3、面层的制备:将步骤S1中制得的天然蚕丝纤维与植物纤维按照相应的配比进行搅拌混合20-30min,然后在160-180℃下熔融,经过滤、纺丝、牵伸、成网、热轧定型即得;
S4、隔离层的制备:将粘胶纤维、铜氨纤维、涤纶纤维和竹炭纤维按照相应的配比进行搅拌混合30-40min,然后再向其中加入马齿苋、黄芩、蒲公英继续混合10-20min,随后在200-240℃下熔融,经过过滤、纺丝、牵伸、成网、热轧定型即得;
S5、尿不湿的制备:将内表接触层、面层、隔离层、吸湿层和底层通过热轧复合和印花处理固定在一起。
与现有技术相比,本发明具有如下有益效果:
本发明中内表接触层由于与婴幼儿的生殖系统直接接触,采用天然蚕丝纤维纺织而成蚕丝层,由于蚕丝中含有丰富的丝素、丝胶蛋白,与皮肤具有较强的亲和力,对皮肤无刺激、无过敏反应且渗透力强,保持干爽,还能保持水分平衡,提高使用舒适度;面层通过天然蚕丝纤维和植物纤维混纺而成,柔软贴身、丝滑透气、绿色健康,其与婴幼儿皮肤贴合时,可对婴幼儿皮肤进行保护,减少摩擦力,防止发生皮肤过敏或者引起婴幼儿不适,此外,通过加入植物纤维能在保证品质的基础上,降低了产品成本,增加了市场竞争力;通过设置吸湿层快速吸收液体,且液体不易向外渗透,反渗透性能好,底层的设置防止液体外渗。
本发明中的产品在使用过程中亲肤性好、对皮肤无刺激、无过敏反应、抗菌消炎,使用时柔软舒适、干爽透气、防止皮肤瘙痒、红屁股等症状的发生,大大提高使用体验。
