Modeling Locking Angle of the Multi-layered Biaxial Weft Knitted Fabric in Shear Deformation

摘要

This paper introduces the construction of the multi-layered biaxial weft knitted fabric (MBWK fabric) and studies the locking angle of this kind of fabric. Moreover, a locking angle model of the MBWK fabric is established for the first time according to its unique construction. Two kinds of locking angles are considered under different restraint conditions: the locking angle θ_1 controlled by the inserting yarns and the locking angle θ_2 controlled by the stitch yarns. It is concluded that the ultimate value of the locking angle θ is the larger one of the two angles.
