weak to be lifted by holding at the two corners it could be transferred from the frame of the apparatus to another flat support for drying only by putting the flat surface on the frame and carefully turning the frame upside down the procedure of example 1 was repeated except that the wet mat was lightly sprayed with a 0 5 active solution of soropon u00ae sf 78 sodium dodecylbenzene sulfonate from gaf the wet mat now was strong enough to be lifted up from the frame by holding it at two corners and transferred directly to another support for drying the finished dried mat showed excellent mat qualities the procedure of example 2 was repeated using a 0 5 solution of blancol u00ae n sodium salt of sulfonated naphthalene formaldehyde condensate from gaf the wet mat again was strong enough to be lifted up from the frame by holding it at two corners for transfer to the drying unit the procedure of example 2 was repeated using a 0 5 solution of nekal u00ae bx 78 sodium alkylnaphthalene sulfonate from gaf with similar effective results in improving the wet strength of the mat the procedure of example 2 was repeated using a 0 5 solution of sipon u00ae esy sodium laurylether sulfate from alcolac inc with similar positive results the procedure of example 2 was repeated using a 0 5 solution of alipal u00ae co 433 sodium nonylphenoxypolyethyleneoxy ethyl sulfate from gaf with similar results the procedure of example 2 was repeated using a 0 5 solution of nekal u00ae wt 27 a dialkylester of sodium sulfosuccinate.
