Abstract
Effects of the fiber and bindings of their thickness for the non-woven fabrics were studied.
The dial-thickness-gauge and slide caliper were used for measuring thickness. So far as the binderweb ratio (x) known as dry pock up, is held constant, the thickness of the products increases proportionally to their weights (Gn) where Dn: thickness by using a slide caliper dn: thickness by using a dial-thickness-gauge An, an: constant Constant An was assumed quantitavely.
In consideration of this constant, having x as a parameter, the experimental equation concerned with the equivalent thickness of non-woven fabrics was established where, Gw is the weight of web and Ab becomes constant A in the case of binder-film itself.
Moreover, the meaning of constant h and m are discussed in detail.
The results are that h and m are the constants relating respectively to the recovering ability of the fiber and to the bonding strength between the two.
