Abstract

A warp which had been slashed with an oil-type size wove very well in the loom, but the results obtained during the desizing and finishing of this warp were poor. The laboratory tests for break ing strength and cohesion indicated that over a period of time a change had taken place in the sized yarn. This change was evi dent as a marked decrease in the breaking strength of the yarn and in its resistance to abrasion. The poor results in finishing were attributed to changes occurring in the size during ageing. The be havior on ageing of sizes of this nature should therefore be in vestigated carefully before use, and too much confidence should not be placed in loom tests alone.
