Provided are systems and methods for producing seamless woven materials that are variable in each of their 3 dimensions. The systems and methods generally operate by altering heddle positions independently to impart three dimensional structure to a woven fabric. Weft yarn is woven into a set of warp yarns that have been individually raised or lowered along a particular cross section, essentially locking the weave into an intended 3 dimensional form.

A loom including a drive transmission shaft connected to a warp beam via a gear member inside a loom frame and inserted in a through-hole formed in a side frame, and a support structure for supporting the drive transmission shaft, the support structure including a first bearing and a second hearing externally fitted to the drive transmission shaft at an interval in an axis line direction. The support structure includes a first bearing case configured to accommodate therein the first bearing and attached to the side frame inside the loom frame and a second bearing case configured to accommodate therein the second bearing and attached to the side frame outside the loom frame.

An interactive loom, which includes a loom-mechanism, a user interface, a loom interface, and a controller. Each cam is in the form of a cylinder rotating about the axis thereof. The circumferential surface of the cam exhibits a determined surface geometry, such that each of a plurality of sections of said circumferential surface corresponds to a respective one of the arms. The circumferential surface further exhibits a respective cross sectional profile and such that each rotational position of said cam is associated with a respective state of lowered and raised arms. The loom-interface includes a motor coupled with the cam, and operates loom-mechanics according to instructions. The controller receives a design from the user-interface and transforms the design into a sequence of states of the arms required for achieving the design. The controller further provides the instructions to the loom-interface. The instructions are associated with state changes of the arms.

An elastic woven fabric comprising weft and warp yarns, the weft yarns including elastic composite yarns each of which comprises an elastic core yarn and a sheath yarn covering the elastic core yarn, and the warp yarns including chemical fiber yarns and/or natural fiber yarns. Each of the elastic composite yarns is in a form of a singly-covered yarn in which the elastic core yarn is covered by a single layer of the sheath yarn helicoidally wound around a periphery of the elastic core yarn, a number of turns of the sheath yarn per 1 meter of the elastic core yarn being in a range of 1,000 to 2,500 T/m. A stretching magnification ratio of each of the elastic composite yarns, in the elastic woven fabric in a weaving process, is retained equal to or less than 1.30 folds based on the elastic composite yarn before weaving.
