The Effect of Sizing on the Weavability of Cotton Yarns—Reply

An account is given of a study of the behaviour of three basic wool weft-knitted structures when subjected to ‘shear at constant length of sides’.

It was found that all the weft-knitted structures studied had a relatively low over-all shear-resistance when compared with other textile structures, such as woven and non-woven fabrics. This low over-all resistance was found to be a combination of a relatively large frictional restraint and a very low resistance once frictional slippage had started. These and other effects are discussed in terms of the geometrical changes occurring within the knitted unit cell during shearing.
