Some Mechanical Factors Influencing Size Application

Abstract

Results presented in this article indicate that (1) at higher slashing speeds warps of 150 denier 40 filament bright viscose pick up less size than at lower speeds when the warp is completely im mersed in the size mix by means of an immersion roll.

(2) The use of a blanket on the squeeze roll (or of fewer weights on the squeeze roll) causes more size to be taken up by the warp than when the squeeze roll is bare. No difference in size dis tribution on the yarn was detected in this case. The use of a blanket on the squeeze roll also increases the drying requirements of the warp.
