The purpose of the study was to compare the effects of certain
abrasion procedures upon specific physical properties of a high wet
modulus rayon. The type of abrasion applied included surface abrasion
in dry and wet condition, edge abrasion in dry condition, and
flexing abrasion in dry condition. Dry flexing...
A study was made of the possibility of producing pulp of viscose rayon grade from three Chilean hardwoods, coigue, tepa, and ulmo. Unbleached pulps were made from the three woods by (1) the neutral sulfite semichemical process with and without steam prehydrolysis, (2) a water prehydrolysis-sulfate process, and (3) the...
