Among the fibers used widely for absorbent applications are cotton, pulp and rayon, all largely cellulosic. One common attribute these materials provide is hydrophilicity which is needed in order to attract, imbibe, and hold fluid in the structure. The objectives of this were to examine the effects produced by some of the important processing and structural factors and generate an understanding of the absorbency characteristics of webs containing the fiber. The investigation included two main experiments. In one, webs containing blends of a cellulose acetate and a hydrophilic cellulose fiber, and a cellulose acetate and a hydrophobic synthetic fiber, were prepared and mechanically bonded using needling and hydroentangling. Web composition, areal density, and bonding level and type were the variables whose effects were examined. In the second, webs containing blends of a cellulose acetate fiber and a low melt polyester fiber were prepared and thermally bonded using a through-air system. In this, the fraction of low melt fiber in the structure and the bonding particulars were the factors of the study.
