In order to investigate the possibility of reducing the amount of super-absorbing polymer (SAP) now used in the disposable sanitary products, sodium hydroxide(NaOH) was adopted to treat the cellulosic fibers used in the nonwoven absorbing cores. Firstly, NaOH of three different concentrations were used,fibers treated with the concentration of 10% have the best absorbent capacity and were filtered out for making absorbing core samples. Then, three nonwoven absorbing core samples with different treated fiber contents plus one sample of untreated fibers were developed and their absorbent capacity and absorbency rate tests were made. After analyzing, the results show that when NaOH treated fiber (concentration of 10%,finishing time of 50s) contents are 50%, nonwoven absorbing core sample has the best absorbent capacity. In the end, the possibility of using complex nonwoven structure to increase the absorbent capacity was also discussed. As a result, the absorbent capacity of the spunlacing nonwoven with complex structure is higher than the single layer spunlacing nonwoven by 33.3%.
