A Study of Tearing in Coated Cotton Fabrics

Abstract

In the first two articles in this series, the influence of fabric construction and of coating characteristics on the mechanical properties of coated cotton fabrics were discussed. All of the coating described in these articles was applied by a knife over blanket technique. In the work described herein, other application techniques were used, including floating knife, re verse roll, and transfer coating. Tearing strengths were measured, and pene tration studied by the stereo technique described previously. High tearing strengths could be obtained by all of the coating techniques, but no simple relationship existed between tearing strength and degree of penetration. Certain of the techniques created a porosity in the penetrated coating which is believed to be responsible for the high tearing strengths obtained.
