A fair correlation has been found (Smith, 2000) between diffusion coefficients and wetting times for cotton twill tape (using a modified Draves wetting test (Chapter 6, Section IIC). 

A fairly good correlation has been observed between the wetting time on cotton skeins, measured by the Draves test, and the dynamic surface tension (Chapter 5, Section IV) at 1 s. To achieve a 1-s dynamic surface tension value, yls, that does not change much with decrease in surfactant concentration, a bulk phase surfactant concentration of at least 5 x 10-4 M is required (Rosen, 1990). 

Wetting times for some surfactants, using the Draves test at 25°C, with a 3-g hook and a 5-g cotton skein, are listed in Table 6-1.
