Description

一种亲水孖纺非织造布产品的生产方法
技术领域
本发明涉及孖纺技术领域,具体涉及一种亲水孖纺非织造布产品的生产方法。
背景技术
非织造布又称无纺布,是由定向的或随机的纤维而构成。当前,非织造产业正欣欣向荣的发展,非织造布在日常生活中已扮演着愈加重要的角色,在医用材料、过滤材料、服用材料、装饰材料、卫生用品擦拭用材料、土工和建筑等领域的应用已十分普遍。在擦拭产品中,被称作“孖纺”的非织造布是含量最大的基本材料。孖纺产品是通过MPM熔喷工艺设备技术生产出来的高温超细纤维,与天然木浆纤维等通过气流混合成网,并经高温热合缠结铺网而形成的多纤共混新型复合非织造材料。孖纺新材料主要可以用于高档湿巾,面膜,医疗手术衣卫生医疗保健用品,还可用于卫生巾、尿裤底膜、乳垫等产品,广泛应用于卫生用品、医用材料、日常生活、工业过滤、隔音隔热等工业领域。
孖纺非织造布是在传统的熔喷非织造布工艺上发展而来,其产品兼具熔喷法非织造布和水刺法非织造布特点。孖纺非织造布原料简单、工艺先进、生产过程无排放,生产成本大大低于传统的胶合干法纸、水刺非织造布及木浆水刺布。然而,目前市面上的孖纺非织造布原材料通常只有熔喷PP(聚丙烯)和木浆,由于熔喷PP和木浆的吸水性能较差导致生产出来的传统孖纺非织造布亲水、吸液、保液能力差。现有孖纺产品技术生产出来的孖纺产品存在着亲水效果差,产品吸液速度慢,甚至不吸液的不足。目前市场上对非织造布进行亲水处理方式大多是在PP(聚丙烯)当中混合添加亲水母粒,如申请号为201910280464.5的中国专利公开了一种擦拭材料及其制作方法,该擦拭材料是将聚丙烯母粒、亲水母粒按配比混合后,采用熔喷法成布。但亲水母粒与PP混合再通过工艺加热管道输送后才到模头喷丝,亲水母粒会景响PP分子链,改变PP的性能,而且亲水母粒在加热过程中并不能与PP完全融合,亲水效果不是很理想。
而非织造布无论是在医卫材料还是在服用、擦拭用材料方面均对亲水性能有着较高的要求。如在医疗卫生领域,消毒湿巾、伤口敷料、止血贴、绷带、吸液垫等均要求具有良好的吸收血液、药液性能;吸收性用即弃材料,如婴儿尿布、妇女卫生巾、成人失禁垫等,对材料亲水性要求更高;在家庭卫生领域,婴儿揩布、餐具、炊具的清洁布等材料无一不对亲水性能有相应的要求。随着亲水性用品数量的增加,对非织造布亲水性能的要求也不断提高。因此,孖纺产品存在的亲水效果差,产品吸液速度慢,甚至不吸液的问题大大限制了其在卫生用品领域和工业过滤材料领域上的应用空间,限制了孖纺非织造布产品的发展。
发明内容
本发明的目的在于针对现有技术的不足而提供的一种亲水孖纺非织造布产品的生产方法。采用该方法生产孖纺产品能够大幅度提升孖纺产品亲水性、吸水、保水性能,生产得到的孖纺非织造布产品的亲水效果好、吸液、保液性能强,柔软亲肤。
为实现上述目的,本发明采用如下的技术方案:
一种亲水孖纺非织造布产品的生产方法,包括以下步骤:
(1)原料备用:按照木浆纤维∶熔喷PP∶亲水母粒的质量比为(3~6)∶(7~4)∶(0.1~0.3)的比例取各原料备用,在PP上料系统中添加亲水母粒,通过挤出机设备的加热使亲水母粒和熔喷PP材料混合均匀并熔融为流体,备用;将木浆纤维开松成单纤维状态备用;
(2)熔喷空气处理:通过空压机输出压缩空气,并将输出的压缩空气进行除湿、过滤处理,去除空气中的潮气和粉尘,然后将压缩空气输送到空气加热器内加热,加热温度为230~280℃,加热时间为30min;最后将处理后的空气输送至模头;
(3)气流辅网成形:经计量泵将融化的喷熔PP+亲水母粒输送到模头内,计量泵和模头温度控制在230-280℃,将通过处理后的压缩空气对模头喷丝孔挤出的熔喷PP细流进行牵伸,形成超细纤维并凝聚在凝网帘上,同时使用气流方法将单纤维木浆凝集在凝网帘上,与熔喷PP超细纤维混合,并通过熔喷PP纤维的自身粘合成形;
(4)压花:使用压花模具对成形后的孖纺非织造布表面进行压花处理,压花辊温度≤100℃;
(5)亲水处理:将以下重量份数的组分:乙氧化十三烷醇50~70份,多库脂钠20~30份,混合,得到亲水剂;将亲水剂配制成质量浓度≤0.3%的溶液,然后通过雾化喷淋装置将亲水剂均匀的喷涂在压花处理过的孖纺非织造布表面,待亲水剂完全被孖纺非织造布吸收;
(6)卷取:将吸收过亲水剂的孖纺非织造布放置在干燥通风的室温环境里12~24h,等孖纺非织造布干透后便可卷取。
进一步的,上述的亲水孖纺非织造布产品的生产方法,步骤(1)中挤出机设备加热的温度为200-250℃。
上述的亲水孖纺非织造布产品的生产方法,步骤(3)中熔喷后形成的非织造布在室温冷却1~2h。
上述的亲水孖纺非织造布产品的生产方法,步骤(5)中对孖纺非织造布进行亲水处理,以占孖纺非织造布原料总质量的比例算,添加亲水剂的用量≤0.2%。
进一步的,所述亲水剂的组分还可进一步包含重量份数为3~5份的抗菌组分,所述的抗菌组分优选羧甲基壳聚糖或季铵盐类抗菌剂,所述的季铵盐类抗菌剂为十二烷基二甲基苄基氯化铵、十八烷基二甲基苄基氯化铵、十六烷基二甲基苄基氧化铵等中的一种。
本发明所用到的亲水母粒是以聚丙烯为载体生产得到的,能够赋予PP纤维亲水性能,耐冲洗、分散性佳,可通过市售得到。亲水母粒用于非织造布的生产,能够赋予非织造布高效亲水性能及透水性能好的特性,而且具有保留产品原有的机械物理性能、强度、布面光洁度、爽滑度、不起毛、纤维不易剥落、透气性好的特点。在本发明中原料中添加亲水母粒进行生产孖纺非织造布产品,能够增加聚丙烯非织造布的极性,促进水分对聚丙烯非织造布的迅速渗透,提高产品的亲水性和透水性,使生产得到的产品具有高效持久的亲水性能。
本发明中所用到的亲水剂的成分包括乙氧化十三烷醇、多库脂钠,还可进一步添加抗菌组分,乙氧化十三烷醇和多库脂钠具有优良的亲水性、润湿性,渗透性以及乳化性,采用这两种成分制成的亲水剂喷涂在孖纺非织造布表面能够大大提高产品的亲水、保水性能,提高产品的吸水速度和吸水倍率。在亲水剂成分中可进一步添加抗菌组分,抗菌组分优选具有较强亲水吸湿性,良好透气性和广泛抗菌抑菌性的羧甲基壳聚糖或具有亲水性和广谱、高效杀菌抑菌性能的季铵盐类抗菌剂;采用进一步添加抗菌组分的亲水剂对孖纺非织造布进行亲水处理不仅可提升孖纺产品的亲水性、透气性、吸水、保水性能,还可进一步提高非织造布产品的抗菌性能。
本发明的有益效果为:
本发明提供了一种亲水孖纺非织造布产品的生产方法,在该生产方法中,首先在PP上料系统中添加了亲水母粒,使亲水母粒和PP材料经过挤出机设备的加热,使两种材料混合在一起,通过熔喷模头的作用形成丝状,形成产品,使生产得到的孖纺非织造布产品在总体性能具备一定亲水的功能。
其次,在本发明的孖纺生产线上,采用配套的雾化喷淋系统装置进行在线直接添加亲水剂,能大大的改善孖纺产品亲水性和提升产品吸水性能。通过雾化喷淋系统装置在孖纺生产线上直接添加本发明所述的亲水剂,亲水剂不必经过模头加热处理不会影响亲水剂的性能,弥补了添加亲水母粒产品时通过加热处理后影响亲水效果的不足,提升孖纺产品的亲水性,吸水、保水性能,甚至可以实现产品的完全亲水,提高了所制得的孖纺产品的应用范围。
本发明经过研究试验表明,在所生产的孖纺产品中添加一定比例的亲水母粒和亲水剂,通过在产品中多层方式和位置的添加亲水材料,能够使产品材料满足亲水功能,采用本发明方法生产得到的孖纺非织造布产品的亲水效果好、吸液、保液性能强,柔软亲肤,能够满足消费者对孖纺产品亲肤和吸液功能效果的要求。而且本发明经过大量的现场实践验证,双重添加功能性助剂的工艺组合,精准优化升级了孖纺工艺流程,精确掌握了亲水母粒、亲水剂的理想组合比例;达到稳定产品自身性能的同时,大幅度提升产品的亲水性能和保水性能。采用本发明方法能有效改变孖纺非织造布表面的润湿性能,提升无纺布的亲水性,可使液体快速传导到芯体中。 而且,采用本发明方法制得的产品微生物检测满足国标要求,抗菌性能好。
采用本发明方法生产得到的亲水孖纺非织造布产品具有如下优势:(1)产品的接触角均低于45°,初始透水时间(s)≤2 s,表明其亲水性能好;(2)5微米的超细纤维,具有独特的超级柔软特性,亲肤感更佳;(3)10倍以上保液能力,独创的生产工艺,使其具有无与伦比的吸水保液性能;(4)基布为天然木浆,产品更易降解更为环保;(5)柔韧不掉屑,超细纤维与天然木浆混合缠结成网,耐揉搓不掉屑。
