摘要： The present invention relates to cross-linked cellulosic fiber having improved absorbency characteristics when compared to conventional cross-linked fibers. The cross-linked cellulosic fiber is obtainable by reacting pulp in the sheet or fluff form with one or more reagents selected from organic molecule having acid and aldehyde functional groups “acid aldehydes.” The invention also relates to a method of producing the cross-linked fiber. The method includes heating the treated cellulosic fibers to promote intrafiber cross-linking. The cross-linked fibers are characterized by having an improved centrifuge retention capacity, fluid acquisition rate, resiliency, absorbent capacity, absorbency under load, and other absorbent properties. The inventive cross-linked fibers are useful in forming absorbent composites, and in particular absorbent cores for use in absorbent articles.
摘要翻译：本发明涉及与常规交联纤维相比具有改善的吸收性能的交联纤维素纤维。交联的纤维素纤维可通过将纸浆或绒毛形式的纸浆与一种或多种选自具有酸和醛官能团“酸醛”的有机分子的试剂反应而获得。本发明还涉及交联纤维的制造方法。该方法包括加热经处理的纤维素纤维以促进纤维内交联。交联纤维的特征在于具有改进的离心机保留能力，流体获取速率，弹性，吸收能力，负载下的吸收性能和其它吸收性能。本发明的交联纤维可用于形成吸收性复合材料，特别是用于吸收制品的吸收芯。
