Weaving stresses cause structural disintegration of the yarn due to fibre plucking and inter-fibre slippage. Geometrical parameters of the sized yarn like packing density and size penetration play important role in preventing the structural disintegration of the yarn. Increase in squeeze pressure increases both packing density and size penetration which ultimately improve fibre-to-fibre and fibre-to-size anchorage and hence result in improved surface integrity and weavability.</span>
