Woven structures

Woven fabrics are the most common type of textile structures used for protective applications. Depending on the degree of interlacement. Woven fabrics consist of two sets of yarns mutually interlaced into a textile fabric structure. The threads that run along the length of the fabric are called warp or ends, while the threads that run along the width of the fabric from selvedge to selvedge are referred as weft or picks. Warp and weft yarns are mutually positioned under the angle of 90°.

Mechanical properties of woven structures depend on:
– type of raw materials
– type and count of warp and weft yarns
– yarn density
– type of weave structure
Warp and weft direction: Highest strength
Bias direction: Lower mechanical properties, higher elasticity and lower shear resistance.

Woven structures in products

Basket weaving, basketry, or basket making is the process of weaving pliable materials into a basket or other similar form. People and artists who weave baskets are called basket makers and basket weavers. Basketry is made from a variety of fibrous or pliable materials—anything that will bend and form a shape. Examples include pine straw, stems, animal hair, hide, grasses, thread, and fine wooden splints. Indigenous peoples are particularly renowned for their basket-weaving techniques. These baskets may then be traded for goods but may also be used for religious ceremonies.

One thought on “Woven structures

  1. So how does weaving change how we design? Is it the enabling of directionality playing with the direction and stiffness of the warp and weft? Is it the lack of scaffolding due to the length of fibrous strips and the sequence of weaving? etc.
