tubular weaving

Industrial tubular weaving is a computer-guided process that has similarities with basket weaving. The warp and weft are interwoven to create a dimensionally stable, seamless structure. In this case continuous strips of polyethylene (PE) are woven into a tube, which will be filled with animal feed and sealed to form sacks. PE is a lightweight and very tough material, see also ballistic material or humble milk carton? Suitable materials other than plastic filaments include natural fibres, high performance materials (such as carbon and aramid fibre) and metal wire.
