Abstract
ABSTRACT Drying of Poly(vinyl acetate) latex films has wide application in the industries of synthetic fibers, adhesives, coatings, paints, etc. In this investigation, drying of Poly(vinyl acetate) latex film was studied experimentally in a drying tunnel where the air velocity and temperature were controlled. The water evaporation rate was obtained by weighing the latex film during the drying process. The weight loss of latex was measured for different polymer concentrations, film thicknesses, drying areas, temperatures, and air velocities. Results emphasize the important role of these parameters on the relative water transport from the latex film. Increasing air velocity and temperature leads to a significant increase of the weight loss of latex and drying rate. Changing other parameters affects only the rate of weight loss but not the constant drying rate.
