TECHNICAL FIELD
The present disclosure relates to a field of the textile industry, and in particular to systems, devices, and methods for three-dimensional surface weaving.
BACKGROUND
Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
Weaving is one of humanity's oldest technologies, which is related to clothes, architecture, and aerospace industry. The interweaving of wraps and wefts produces a plain fabric which is hard to deform in the directions of wrap thread and weft thread.
In 1804, Joseph Marie Jacquard invented a weaving machine with a jacquard loom which made possible the automatic production of varieties of complex pattern weaving. The weave pattern can set the appearance of fabric, including, e.g., matte velvet, shiny satin, and vibrant multi-color patterns; change the feel of the fabric, from, e.g., rough plain weave to fuzzy terry. The state-of-the-art weaving machine enables the weaving of thousands of heddles with computer-controlled and complex weave patterns due to the electronic version of the jacquard loom. Almost all of the existing weaving machines are designed to weave plain fabric no matter what different materials or complex patterns they apply.
Although there are some hand-woven products with 3D surfaces in our life, e.g., woven rattan chairs, the production process still cannot be automated and industrialized until a weaving machine with a 3D surface weaving function is made.
On the other hand, knitting, as another branch of ancient textile technology, has made huge progress in terms of 3D forming in recent decades. The latest research shows that it is possible to seamlessly knit a garment based on a 3D human model using a state-of-the-art knitting machine. However, there is a limitation in the material due to the structure of knitting knot, the material has to be soft and elastic, e.g., cotton. The knitting fabric shows isotropic properties and poor mechanical properties while being applied tensile force compared with weaving fabric.
Therefore, what is needed are techniques that overcome the above-mentioned disadvantages.

Referring to FIG. 1, a system 10 for three-dimensional surface weaving comprises a jacquard device 100, a weaving device 200 and a roller matrix 300. The system 10 is configured to weave fabric with three-dimensional surface by using wrap threads and weft threads and enables 3D surface weaving function automatically.
Referring to FIG. 2, the jacquard device 100 is configured to selectively raise or lower the wrap threads to form a shed for the weft thread to travel. The shed is a gap allowing the weft thread to interlace. In some embodiments, the jacquard device 100 can be located directly above the weaving device 200. The jacquard device 100 can be a full jacquard device 100. The jacquard device 100 can include heddles 120 and a rectification board 140. The heddles 120 can be controlled by computer programs to selectively raise or lower the wrap threads. The heddles 120 go through the rectification board 140. The rectification board 140 can unify the lifting direction and magnitude for all selected heddles 120 when the jacquard device 100 is working. The wrap threads and heddles 120 perpendicular to the same horizontal line where there are rings tied on the heddles 120 so that the wrap threads can form a shed as the heddles 120 selectively raise or lower under the control of the jacquard device 100.
Referring to FIG. 3. the weaving device 200 is configured to carny the weft thread into the shed and weave the weft thread on the wrap threads. The weaving device 200 comprises a reed 220 and a shuttle (not shown in FIG. 3), the shuttle is movable along the reed 220 and configured to carry the weft thread. The heddles 120 drawn from the jacquard device 100 dive into the weaving device 200 to control the wrap threads. The heddles 120 selectively raise or lower the wrap threads to form the shed, then the shuttle carries the weft thread into the shed. After that, the reed 220 moves to interlace the weft thread with the wrap threads.
Referring to FIG. 4, the roller matrix 300 is configured to control the wrap threads to move forward or backward. The roller matrix 300 is mainly responsible for sending or collecting wrap threads individually. The roller matrix 300 includes individually controlled rotate apparatus 320. In some embodiments, one rotate apparatus 320 controls one of the wrap threads to move forward or backward.
Referring to FIG. 5, the rotate apparatus 320 can be driven by a step motor 321, the step motor 321 is configured to drive the wrap thread forward or backward. In an embodiment, the rotate apparatus 320 can further comprise a coil 322, a driving gear 323 and a driven gear 324. The coil 322 is configured to coil 322 the wrap thread. The driving gear 323 is driven by the step motor 321. The driving gear 323 meshes with the driven gear 324, and driving gear 323 and the driven gear 324 are configured to clamp the wrap thread to move forward or backward. The wrap thread is released from the coil 322 and goes through a positioning hole to a position between the driving gear 323 and the driven gear 324. The driving gear 323 is driven by the step motor 321 which could rotate forward or inverse. The driving gear 323 meshes with driven gear 324, so the wrap thread is clamped inside. As the driving gear 323 rotates, the wrap thread will be sent or collected to realize individually controlling function.
The wrap threads come from rotate apparatus 320 installed on the roller matrix 300. The rotate apparatus 320 is controlled individually to forward or reverse rotate according to W-code converted from a three-dimensional surface, so that the attached wrap thread is able to be longer or shorter. As the wrap threads can be shortened during weaving process, the three-dimensional surface can be produced.
