异型涤纶纤维与木浆纤维复合水刺湿巾布及其制备方法
技术领域
本发明涉及木浆湿巾布制造技术领域,具体地说是一种异型涤纶纤维与木浆纤维复合水刺湿巾布及其制备方法。
背景技术
在非织造布加工技术中,水刺法是通过高压水流对纤网进行连续喷射,在水力作用下使纤网中纤维运动、位移而重新排列和相互缠结,从而使纤网得以加固而获得一定的物理机械性能。水刺非织造材料具有强度高、手感柔软、悬垂性好、无化学粘合剂以及透气性好等特点,广泛应用于各个领域;水刺复合技术是以微细高压水流为手段,通过对两种或两种以上材料的穿透,使纤维在两种或两种以上材料界面相互缠结而形成一个功能性整体的非织造材料生产技术,由于多种技术的交叉、渗透和融合,使水刺复合产品的性能和功能更加丰富,大大拓宽了水刺产品的应用领域。
水刺复合技术有多种复合形式,其目的是为了使复合后的材料的某些性能或某些功能得到改善或提高,使复合后的材料既具备基体材料的性能,又具有复合层材料的某些性能或功能,从而扩大了复合材料的应用。
木浆纤维吸湿性能优良,价格低廉,与涤纶纤维复合之后,使得复合材料的强度、吸水性、柔软性等方面都有显著的提高,广泛用于防护服、手术服等方面的。
但是传统木浆涤纶与水刺布复合后,在厚度方面达不到要求,在应用时往往会受到限制。
发明内容
本发明的目的是克服现有技术的不足,通过使用部分或全部替代中空涤纶代替原有涤纶、改变木浆纤维百分比等方式,来增厚木浆水刺布,并能进一步提高复合材料的强度、吸水性、柔软性。
为实现上述目的,设计一种异型涤纶纤维与木浆纤维复合水刺湿巾布,其特征在于,采用涤纶纤维25wt%、中空涤纶纤维25wt%和木浆纤维50wt%通过水刺法制备而成;或者采用中空涤纶纤维50wt%和木浆纤维50wt%通过水刺法制备而成。
一种异型涤纶纤维与木浆纤维复合水刺湿巾布的制备方法,其特征在于采用如下制备步骤:
(1)原料准备:采用称量机称取涤纶纤维25wt%、中空涤纶纤维25wt%;或者称取中空涤纶纤维50wt%和木浆纤维50wt%;
(2)原料初步开松混合:将原料投入混棉窗子开棉机进行初步开松混合,混合纤维的重量规格如下:中空涤纶纤维1.67D*38MM,111.5kg;涤纶纤维1.5D*38MM,110KG;
(3)混合:采用混棉机对初步开松后的原料进行进一步的均匀混合;
(4)精开松:采用开棉机对均匀混合后的原料进行精开松;
(5)喂料调整:将精开松后的原料依次经末道棉箱、气压棉箱喂入梳理机;
(6)梳理成网:梳理机将精开松后的原料梳理成纤维网,其中梳理机的主锡林速度900-1100m/min,工作辊100-119.7m/min,剥离辊100-119.7m/min;
(7)第一次水刺加固:所述纤维网进入水刺机进行第一次水刺法操作,纤维网上方冲下的水针将纤维网的上表面纤维穿透到底部,水针在底网上的反弹作用使纤维网的下表面纤维与上表面纤维相互缠绕打结,使纤维网加固形成基布;
(8)造纸法涂木浆粕:通过湿法造纸机将木浆纤维形成木浆粕并均匀铺于所述基布上;
(9)第二次水刺加固:涂布有木浆粕的基布再进入水刺机进行第二次水刺法操作,纤维网上方冲下的水针先将木浆粕中的短纤维冲散并充塞到所述基布的纤维孔隙中,同时部分短纤维也与基布中的纤维缠绕抱合,加强了木浆粕与基布的复合;
(10)烘干:将与木浆粕充分复合的基布进行烘干得复合基布;
(11)卷绕:将烘干后的复合基布通过卷绕机进行卷绕,得成品。
本发明与现有技术相比,将湿法造纸工艺与梳理成网水刺工艺融合在一条生产线上,产品以复合布为主,制备出的产品的突出特点是:吸水性好、抗静电、成网均匀、不含黏合剂,且屏菌、柔软、透气;此外木浆层、涤纶纤维层在线形成,中空涤纶纤维、涤纶纤维与木浆纤维的比例可灵活调整,从而灵活调整产品的厚度。
具体实施方式
现结合实施例对本发明作进一步地说明。
实施例1
本例中采用涤纶纤维25.0wt%、中空涤纶纤维25wt%和木浆纤维50wt%通过如下水刺法制备而成;
(1)原料准备:采用称量机称取上述配比原料;
(2)原料初步开松混合:将原料投入混棉窗子开棉机进行初步开松混合;
(3)混合:采用混棉机对初步开松后的原料进行进一步的均匀混合;
(4)精开松:采用开棉机对均匀混合后的原料进行精开松;
(5)喂料调整:将精开松后的原料依次经末道棉箱、气压棉箱喂入梳理机;
(1)梳理成网:梳理机将精开松后的原料梳理成纤维网,梳理机的工艺参数范围:主锡林速度900-1100m/min,工作辊100-119.7m/min,剥离辊100-119.7m/min;
(6)第一次水刺加固:所述纤维网进入水刺机进行第一次水刺法操作,纤维网上方冲下的水针将纤维网的上表面纤维穿透到底部,水针在底网上的反弹作用使纤维网的下表面纤维与上表面纤维相互缠绕打结,使纤维网加固形成基布,水刺头压力如下:4#水刺压力36Bars,5#水刺压力46Bars,6#水刺压力51Bars,7#水刺压力54Bars;
(7)造纸法涂木浆粕:通过湿法造纸机将木浆纤维形成木浆粕并均匀铺于所述基布上,浆粕的质量浓度2.5%,流量6.8m3/s,速度49.8m/min;
(8)第二次水刺加固:涂布有木浆粕的基布再进入水刺机进行第二次水刺法操作,纤维网上方冲下的水针先将木浆粕中的短纤维冲散并充塞到所述基布的纤维孔隙中,同时部分短纤维也与基布中的纤维缠绕抱合,加强了木浆粕与基布的复合;
(9)烘干:将与木浆粕充分复合的基布进行烘干得复合基布,烘干时先采用3个烘筒依次烘干,3个烘筒温度分别为125℃-135℃;再采用4个烘干网进行烘干,烘干网的温度为135℃-140℃;

实施例2
本例与实施例1的制备方法相同,只是原料中空涤纶纤维50wt%和木浆纤维50wt%。此配比下产品的各项性能参数测试报告如下:
本发明中,木浆纤维吸湿性好,在水刺时,木浆纤维吸水膨胀,使迎水面积变大,水针带动纤维运动的效率提高,纤维的缠结效果好;
涤纶纤维模量高,弹性和延展性好,耐磨性也好,因此采用三层复合材料耐磨性好,且三层结构使木浆纤维的流失率减小;
另外,本发明中创新性的采用了中空涤纶纤维,纤维的卷曲多、厚度增大、吸水性好,使得得到木浆复合水刺产品厚度大、轻便柔软、干爽透湿,改善产品外观性能和使用性能。
本发明增加了水刺布的种类,拓展了水刺产品的应用领域,推动了水刺非织造布行业的技术进步。木浆具有价格低廉、亲水性好、绿色环保、成品手感柔软等优点;水刺-木浆粕水刺成网技术在揩布、妇女卫生用品、儿童和个人护理、医疗,如。手术服、防护服、手术罩布、湿巾等产品中广泛应用。今后,水刺-木浆粕水刺成网技术在土工合成材料、交通运输、医疗、建筑、各种防护服等应用领域产品的开发和研究也将越来越深入。
