Abstract: The invention relates to cellulose fluff pulp products that are debondable into fluff with markedly lower energy input, to a process for making the products, and to absorbent products using the fluff. Most of the pulp products show no reduction in liquid absorbency rate from that of untreated fiber and significantly higher rates than pulps treated with the usual debonding agents. The products are made by adhering fine noncellulosic particles to the fiber surfaces using a retention aid. The fiber is preferably treated with the retention aid in an aqueous suspension for a sufficient time so that the retention aid is substantively bonded with little or none left free in the water. The fine particulate additive is then added and becomes attached and uniformly distributed over the fiber surfaces with very little particle agglomeration occurring. The fiber is most usually not refined or only very lightly refined before sheeting. However, it may be significantly refined to produce a product having a very high surface area. Kaolin clay is a preferred particulate additive. The treated pulp may be mixed with other fibers before sheeting or after it is debonded into a fluff. The fluff is highly advantageous in the absorbent portions of personal care products such as diapers or sanitary napkins.
Abstract translation: 本发明涉及可剥离成具有显着较低能量输入的绒毛的纤维素短纤浆产品，制造该产品的方法以及使用绒毛的吸收产品。 大多数纸浆产品显示出与未处理纤维相比液体吸收率没有降低，并且显着高于用常规脱粘剂处理的纸浆。 产品通过使用助留剂将细非织造纤维颗粒粘附到纤维表面上而制成。 纤维优选用助留剂在水性悬浮液中处理足够的时间，使得助留剂在水中几乎没有或没有任何残留物基本粘合。 然后加入细颗粒添加剂并变得附着并均匀分布在纤维表面上，发生非常少的颗粒聚集。 纤维通常不是精制的，或者在片材之前只是非常轻微地精制。 然而，可以显着改进以产生具有非常高的表面积的产品。 高岭土是优选的颗粒添加剂。 经处理的纸浆可以在片材之前或在其脱粘成绒毛之后与其它纤维混合。 绒毛在诸如尿布或卫生巾的个人护理产品的吸收部分中是非常有利的。
