alkylamidoalkyl sultaines the remaining compounds 2 24 groups b g are representative of other surfactant materials the experiments used in these examples utilized wet chop e glass two types of e glass were used 1 standard sized cationic e glass and 2 unsized deionized water sized e glass the fiber bundles were 32 mm in length and 15 micron in diameter both the sized and unsized e glass contained 12 16 moisture water pick up the unsized e glass was not a commercially standard material for these tests the surfactant compounds were dissolved in water at various concentrations ranging from 20 ppm 0 002 to 2 5 ppm 0 00025 by weight of the surfactant actives basis in water a given dispersion was matted and was rated on a scale of 1 to 5 a rating of 1 was given to a poorest e glass mat formation where the fiber strands agglomerated and or did not open up as individual fibers the handsheet produced by not using any dispersant was rated as 1 and used as the control the highest quality of dispersed fibers in the handsheet was rated as 5 in which all fibers were separated from each other and the mat was uniform and dense intermediate ratings of 4 3 and 2 were given to e glass handsheets with a gradual trend to clumped fibers and anisotropic formation the difference between integers is considered significant the data was obtained by averaging the sensory observations.
