METHOD FOR MEASURING DISINTEGRATION OF FIBROUS PRODUCT

The present invention provides a method and system for measuring disintegration of a fibrous product. The method comprises disintegration of a sample of the fibrous product in an aqueous solution, optionally promoted by mechanical energy, passing the aqueous solution through a screen to obtain a permeate and retained fraction on the screen, and analyzing at least one parameter from the permeate for example by a gravimetric analysis, an optical analysis, an electrochemical analysis, a volumetric analysis, or combination thereof. Advantages include adjustabilxity, speed, and high correlation with actual flushability or repulpability of the fibrous product, and utility in a process for manufacturing a fibrous sheet exhibiting con- trolled disintegration, such as a flushable or repulpable fibrous sheet. 本发明提供了用于测量纤维产品的崩解的方法和系统。该方法包括将纤维产品的样品在水性溶液中崩解，任选地通过机械能进行促进，将水性溶液通过筛网以获得透过物和筛网上的保留级分，并由透过物分析至少一种参数，例如通过重量分析、光学分析、电化学分析、容量分析或其组合。其优点包括可调节性、速度和与纤维产品的实际可冲散性或再浆化性的高度相关性，以及在用于制造表现为受控崩解的纤维片(诸如可冲散或可再浆化的纤维片)的方法中的实用性。
