In this study, for the first time, a composite fluff pulp was produced based on the combination of softwood (i.e., long-length fiber), hardwood (i.e., short-length fiber), non-wooden pulps (i.e., bagasse) and bentonite, with specific amounts to be used in hygienic pads (e.g., baby diapers and sanitary napkins). After the defibration process, the manufactured fluff pulp was placed as an absorbent mass in diapers and sanitary napkins. Therefore, tests related to the fluff pulp, such as grammage, thickness, density, ash content, humidity percentage, pH and brightness, tests related to the manufactured baby diapers, such as absorption capacity, retention rate, retention capacity, absorption time and rewet, and tests related to the sanitary napkin, such as absorption capacity and rewet, were performed according to the related standards. The results demonstrated that increasing the amount of bagasse pulp led to increasing the ash content, pH and density of fluff pulp and decreasing the brightness. The addition of bentonite as a filler also increased ash content and pH of fluff pulp. The results also demonstrated that increasing of bagasse pulp up to 30% in combination with softwood pulp led to increasing absorption capacity, retention rate, retention capacity, absorption time and rewet of baby diapers and of sanitary napkins.
在这项研究中,首次基于软木(即长纤维)、硬木(即短纤维)、非木质纸浆(即甘蔗渣)和膨润土的组合生产了复合绒毛浆,并确定了在卫生垫(如婴儿尿布和卫生巾)中使用的具体用量。在纤维化过程之后,制造的绒毛浆被放置在尿布和卫生巾中作为吸收体。因此,根据相关标准,对绒毛浆进行了相关测试,如定量、厚度、密度、灰分含量、湿度百分比、pH 值和亮度;对制造的婴儿尿布进行了相关测试,如吸收能力、保留率、保留能力、吸收时间和回湿;对卫生巾进行了相关测试,如吸收能力和回湿。结果表明,增加甘蔗渣浆的用量会导致绒毛浆的灰分含量、pH 值和密度增加,而亮度降低。膨润土作为填料的添加也会增加绒毛浆的灰分含量和 pH 值。结果还表明,将软木浆与 30%的甘蔗渣浆结合使用,会增加婴儿尿布和卫生巾的吸收能力、保留率、保留能力、吸收时间和回湿。
