MEIKASURF

Dispersant for hydrophobic fibers​

Various synthetic fibers and inorganic fiber have a problem of making paper in wet method since those fiber surfaces are hydrophobic and not familiar with water and then occurs coagulation of each fiber and foaming.
It is able to obtain good formed sheet without binding fibers by pre-treating by dispersants which make fibers be friendly with water and induces the repulsion of each fiber.

 

 

Test example 1 The method of judgement of the condition of dispersion in water.
  • Dispersing PPS(Polyphenylenesulfide)fibers

Appearance for each recipe after mixing PPS fibers with dispersant.

against fiber
  1.0
After stirring for 1 min

The sample added dispersant shows good dispersed condition and blank sample shows quickly floating of fibers instead.
