Abstract
The reaction of wool with toluene-2,4-diisocyanate and hexamethylene diisocyanate is described, The treated wools exhibit greater resistance towards solubilization in hot acid and alkali and towards attack by several other chemical agents. The wet single-fiber stress-strain properties exhibited below 30% extension are only slightly affected by treat ment with isocyanates. The values for stress at break and elongation at break, however, are considerably lowered by treatment with difunctional isocyanates. but not with phenyl isocyanate. Fabric stiffness and crease recovery are only slightly affected by the iso cyanate pickups studiedKeywords
