Abstract
Sizing changes the geometry of a fabric, while the fabric gains a definite effect by the sizing. It is necessary to evaluate inclusively the internal structure of sized fabrics for characterization of them.
By the mercury intrusion method, only the internal volume of the radius region less than ca. 180 μm can be measured but there is much more volume of larger radius region in a fabric. We applied the equilibrium liquid absorption method to evaluate the internal volume/radius distribution in several sorts of sized fabrics. Summing up the internal volumes estimated by these two procedures gave a profile of major internal volume/radius distribution in the sized fabrics.
The inter yarn or the fabric surface volume of each sized fabric was differ from that of the fabric before sizing. The inter fiber volume in cotton fabrics was well filled with any kind of sizing but in acrylic fabrics was not filled sufficiently with carboxymethylcellulose or starch.
