Angle-interlock fabric is a type of 3D solid fabrics that contains layers of straight weft yarns and binding warp yarns travelling between the face and back of fabric in diagonal directions.
Due to the shearing of the angles between warp and weft yarns, this unique structure can be utilized in applications which demand high bending and shearing flexibility, such as in forming the dome shape in female body amour or 3D shell model.
The following figures demonstrate the design processes of a 5-layer angle-interlock fabric:
The angle interlock fabric required to design consists 5 layers, then the warp repeat: 5+1=6, the weft repeat: 5×6=30.
Stage 1: draw the picks
Stage 2: insert the first end
Stage 3: repeat the insertion of ends until the 6th end
Stage 4: convert the graph into weaving plan
In addition, it is possible to insert wadded warps into the angle interlock fabric:
According to the plan of weave, draft and lifting plan is obtained:
The draft indicates that six heald frames are required for weaving the fabric, and each heald frame controls one set of ends. The lifting plan indicates the movements of the heald frames. For example, the first row indicates heald frame 1 moves up and others moves down, the second row indicates heald frame 1, 2 and 6 move up and others move down. Moreover, the pegging of the pattern cards is done according to the lifting plan. The pattern cards control the movement of the heald frames, if there is a peg in the hole, the correlative heald frame will move up, otherwise it will move down.
Take the first six rows in the lifting plan as example, the pegging is:
During weaving, the heald frames moved up and down according to the arrangement of pegs in pattern cards and formed angle interlock fabric.
