Prior methods of creating curvature in woven materials generally comprise weaving flat fabric (i.e., fabric having variation in at most two dimensions), cutting the flat fabric into pieces, and then stitching these pieces together, thereby imparting a three-dimensional structure to the woven article through the cutting and stitching process. Such methods may be used to build complicated geometry in clothing, but have a number of downsides or limitations. For instance, the amount of labor involved tends to increase with complexity of the three-dimensional geometry, making existing methods less efficient. Also, clothing with complex geometry tends to require a greater number of seams, and the seams created by the cutting and stitching process can be detrimental to structural performance. Moreover, cutting and stitching of flat fabric may generate a substantial amount of waste in the manufacture of woven products. Within the apparel industry alone, it has been estimated that at least 15% of flat woven fabric is discarded during the cutting operation. Thus, there is a need for systems and methods that can efficiently manufacture irregularly shaped woven fabrics with topographical three-dimensional structure having improved structural performance, and with reduced material wastage.
Disclosed herein are systems and methods for manufacturing irregularly shaped woven fabrics with topographical three-dimensional structure. The systems and methods described herein may provide a variety of benefits compared to prior systems and methods of weaving, which generally comprise weaving flat fabric, cutting the flat fabric into pieces, and stitching these pieces together. For instance, the systems and methods described herein may reduce the number of seams or discontinuities (and therefore structural weaknesses) in a woven material, reduce the generation of waste from the process of manufacturing a woven material, impart better resistance against the elements (such as wind, rain, cold, or sun) to a woven material due to the reduced number of seams or discontinuities, improve the comfort or fit of a woven material, or allow for customization of fit of a woven product to a specific user of the woven material.
The systems and methods described herein generally operate by altering heddle positions independently to impart three dimensional structure on a woven fabric. Weft yarn may be woven into a set of warp yarns, each of the warp yarns having been individually raised or lowered to form a particular local topography, essentially locking the weave into an intended three-dimensional form. This may be accomplished by not only shedding heddles opposite of neighboring heddles, but also by varying heddle position within a shedding group. The systems and methods described herein may be used to produce textile products, such as garments, personal protective equipment, or outdoor goods.

Described herein 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.
As used herein, the terms “string”, “thread”, and “yarn” are used interchangeably.
As used herein, the terms “warp string” and “weft string” refer to the two basic components used to turn string into a woven article. The term “warp string” refers to a lengthwise or longitudinal string that is held stationary in tension on a loom during a pass of a “weft string” along a direction substantially transverse to the direction along which tension is placed on the warp string. The term “weft string” refers to a string that is woven above and under the warp strings that comprise the woven article, such that that warp and weft string are held together with a length of the warp threads being substantially perpendicular to a length of the weft threads.
The loom may comprise a plurality of heddles, each of which may be individually raised or lowered along one or more axes of a heddle plane of the loom. Each of the heddles may be moved to a plurality of discrete positions along a longitudinal axis of the heddle planes, as described herein (for instance, with respect to
For instance, as shown in
The total differential distance between a top most heddle and a bottom most heddle may be at least 1 mm, at least 2 mm, at least 3 mm, at least 4 mm, at least 5 mm, at least 6 mm, at least 7 mm, at least 8 mm, at least 9 mm, at least 10 mm, at least 20 mm, at least 30 mm, at least 40 mm, at least 50 mm, at least 60 mm, at least 70 mm, at least 80 mm, at least 90 mm, at least 100 mm, at least 200 mm, at least 300 mm, at least 400 mm, at least 500 mm, at least 600 mm, at least 700 mm, at least 800 mm, at least 900 mm, at least 1 m, at least 2 m, at least 3 m, at least 4 m, at least 5 m, at least 6 m, at least 7 m, at least 8 m, at least 9 m, or at least 10 m, or a distance that is within a range defined by any two of the preceding values.
In one embodiment, individual heddles or subsets of heddles are moved to different positions. Such different positions may be at different heights, such that they lie along or form a curved, curvilinear, or non-linear profile on the heddle plane. Two or more of the positions may be staggered relative to one another. Two or more of the positions may lie along a transverse axis of the heddle plane. Two or more of the positions may lie along a line that traverses non-orthogonally to the longitudinal axis of the heddle plane, such as in an upward-sloping or downward-sloping manner along the heddle plane. A plurality of positions may lie in a zig-zag fashion or profile along the heddle plane. A variety of different profiles may be achieved by modulating the positions of individual heddles on the heddle plane. In some instances heddles are arranged into sets, each with at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, or more heddles that are moved together, through at least some steps in the weaving process.
The individual raising or lowering of heddles to a plurality of positions may create a first local curvature 191a of the warp strings. The first local curvature may be locked into the seamless woven material by weaving one or more weft strings between the individually raised or lowered warp strings. The weft strings may be woven between the individually raised or lowered warp strings in a number of manners. For instance, the local curvature may be locked in using a one operation process. The one operation process may comprise weaving a weft string alternately between the warp strings while they are locked into their individually raised or lowered positions (such as the first, second, third, fourth, fifth, and sixth positions depicted in
Alternatively or in combination, the local curvature may be locked in using a two operation process. The two operation process may comprise a first operation of weaving a weft string under or above the individually raised or lowered warp strings (depending on whether each warp string was in a raised or lowered position). The positions of the individually raised or lowered warp strings may then be inverted (i.e., raised warp strings moved to lowered positions, and lowered warp strings moved to raised positions). The two operation process may comprise a second operation of weaving the same weft string above or under the inverted warp strings (opposite the weaving in the first operation), locking the first local curvature into the seamless woven material. Alternatively or in combination, the first and second operations may be accomplished using different weft strings.
The process of imparting local curvature into the seamless woven material may be repeated in order to produce variability in each of the three dimensions of the seamless woven material. For instance, as depicted in

Each motor may comprise a brushed direct current (DC) motor, a brushless DC motor, a servo motor, or a stepper motor. Each motor may be configured to move (e.g. translate) each heddle along one or more axes of a heddle plane of the loom.
The actuator system may comprise a plurality of electronic controllers. The electronic controllers may be configured to output electrical signals to the plurality of motors. The electrical signals may control motion of the motors to effect changes in position of one or more of the heddles. For instance, the electrical signals may specify instructions for the motors to turn in order to raise or lower a heddle by a particular distance. The electrical signals may specify instructions for the motors to raise or lower a heddle at a particular speed or acceleration. The plurality of positions may comprise at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 20, at least 30, at least 40, at least 50, at least 60, at least 70, at least 80, at least 90, at least 100, at least 200, at least 300, at least 400, at least 500, at least 600, at least 700, at least 800, at least 900, at least 1,000 discrete positions along a longitudinal axis of the heddle plane, or a number of discrete positions along a longitudinal axis of the heddle plane that is within a range defined by any two of the preceding values. A distance between two adjacently spaced discrete positions may be at least about 0.01 mm, at least about 0.02 mm, at least about 0.03 mm, at least about 0.04 mm, at least about 0.05 mm, at least about 0.06 mm, at least about 0.07 mm, at least about 0.08 mm, at least about 0.09 mm, at least about 0.1 mm, at least about 0.2 mm, at least about 0.3 mm, at least about 0.4 mm, at least about 0.5 mm, at least about 0.6 mm, at least about 0.7 mm, at least about 0.8 mm, at least about 0.9 mm, at least about 1 mm, at least about 2 mm, at least about 3 mm, at least about 4 mm, at least about 5 mm, at least about 6 mm, at least about 7 mm, at least about 8 mm, at least about 9 mm, or at least about 10 mm, or a distance that is within a range defined by any two of the preceding values. For instance, a distance between two adjacently spaced discrete positions may be within a range from about 0.04 mm to about 0.06 mm.
The electronic controllers may comprise software and/or hardware components. The electronic controllers may include one or more processors and at least one memory for storing program instructions. The processor(s) may be single or multiple microprocessors, field programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), or digital signal processors (DSPs) capable of executing particular sets of instructions. Computer-readable instructions may be stored on a tangible non-transitory computer-readable medium, such as a flexible disk, a hard disk, a CD-ROM (compact disk-read only memory), and MO (magneto-optical), a DVD-ROM (digital versatile disk-read only memory), a DVD RAM (digital versatile disk-random access memory), or a semiconductor memory. Alternatively or in combination, the program instructions may be implemented in hardware components or combinations of hardware and software such as, for example, special purpose computers, or general purpose computers.
For instance, the electronic controllers may comprise a position sensing and feedback functionality, as described herein (for instance, with reference to
In some examples, a positional sensing system may be provided for the plurality of heddles. The positional sensing system may be used to facilitate or improve control of individual heddles. For example, a position sensor may be provided for or operably coupled to each heddle. The position sensor may include, for example, a magnetic field sensor, an optical sensor, or an inertial sensor. Each position sensor may be configured to generate signals in response to changes in position of the corresponding heddle. The signals may be indicative of the positions of the heddles relative to one another, and/or relative to the heddle plane. The signals may vary as individual heddles move between different positions along the heddle plane. The electronic controllers may be configured to receive and analyze signals from the position sensors to determine a local position of each heddle. The local position of each heddle may be computed relative to a coordinate system for the heddle plane. The electronic controllers may be configured to control motion of the motors to effect changes in position of one or more of the heddles, based on the detected positions of the heddles.
For instance,
The controller may be configured to control and track the position and/or movement of the plurality of heddles, based on positional feedback obtained from the sensors as the heddles move along the heddle plane.
An input may be initially provided to the control system. The input may comprise one or more desired positions of the plurality of heddles. The desired positions may be associated with a desired curved, curvilinear, or non-linear profile on the heddle plane. The controller may be configured to generate signals for controlling the plurality of actuators to move the heddles along the heddle plane based on the input. One or more of the heddles may be selectively activated and moved along the heddle plane. The positions of individual heddles may be determined based on sensing signals obtained by one or more position sensors. In some instances, the movements, such as the velocities and/or accelerations, of individual heddles may be determined based on sensing signals obtained by one or more speedometers, accelerometers, and the like. The sensing signals may be generated by the sensors as the heddles move on the heddle plane. The heddles may be configured to move at a speed of at least 1 mm/s, at least 2 mm/s, at least 3 mm/s, at least 4 mm/s, at least 5 mm/s, at least 6 mm/s, at least 7 mm/s, at least 8 mm/s, at least 9 mm/s, at least 10 mm/s, at least 20 mm/s, at least 30 mm/s, at least 40 mm/s, at least 50 mm/s, at least 60 mm/s, at least 70 mm/s, at least 80 mm/s, at least 90 mm/s, at least 100 mm/s, at least 200 mm/s, at least 300 mm/s, at least 400 mm/s, at least 500 mm/s, at least 600 mm/s, at least 700 mm/s, at least 800 mm/s, at least 900 mm/s, at least 1 m/s, at least 2 m/s, at least 3 m/s, at least 4 m/s, at least 5 m/s, at least 6 m/s, at least 7 m/s, at least 8 m/s, at least 9 m/s, at least 10 m/s, or a speed that is within a range defined by any two of the preceding values.
An actual path (which may include an actual position, speed, and/or acceleration) of each individual heddle may be determined based on the sensing signals. The actual path may be compared against the input to determine an amount of deviation (if any) from the desired paths (desired position, speed, and/or acceleration) of the individual heddle. The controller may be configured to adjust the position (and/or speed or acceleration) of one or more of the heddles by adjusting a control signal (such as an electric current or voltage) to the corresponding actuator based on the amount of deviation. The controller may be configured to adjust the position (and/or speed or acceleration) of each individual heddle in this manner.
The corrections may be imparted by any feedback mechanism, such as a proportional-integral-derivative (PID) control mechanism. The heddle positions may be altered over time to form different two-dimensional fabric cross-sections. For instance, the heddle positions may be altered at first, second, third, fourth, and fifth points in time t1, t2, t3, t4, and t5 to form the four profiles shown in
The control system described with respect to
The heddles may assume any possible open form or profile at any point in time. For instance, the heddles may assume a form or profile characterized by arranging the heddles to lie along any single open-ended curve (such as any of those depicted in
As shown in
When, for instance, the first motor 122a is rotated, this rotation may be translated, through the first gear reduction component 125a, to the first pulley 124a, causing the first pulley to rotate. The first heddle string or wire 126a may be wound or unwound along grooves in the first pulley, depending on the direction of rotation of the first motor. Winding of the first heddle string or wire may cause a heddle to move in an upward direction, raising the associated heddle and any warp string that may be wound through the associated heddle. Unwinding of the first heddle string or wire may cause a heddle to move in a downward direction, lowering the associated heddle and any warp string that may be wound through the associated heddle. Thus, rotational motion of the first motor may raise or lower a heddle to any desired position. A similar raising or lowering of other heddles and warp strings may be caused by rotation of the second, third, fourth, fifth, or sixth motors.
Absent the gear reduction components, a motor may be subject to a torque, such as a torque due to a gravitational force or a spring force on a heddle coupled to the motor. The torque may tend to cause undesired rotation of the motor, causing the heddle to move downward when such downward motion is not desired. This may be true even when the motor used is a stepper motor or servo motor. The gear reduction component may significantly slow the downward motion, allowing a weft string to be woven through individually raised or lowered warp strings associated with the heddles before the heddles are able to move an appreciable distance downward. This mode of operation may obviate the need for electrical power to be supplied at times other than when intentional heddle movement to a different position is desired. This may significantly reduce the amount of electrical power required to operate the actuator system.
Though depicted as comprising 6 motors, 6 couplings (each comprising a gear reduction component and a pulley), and 6 heddle strings or wires, the actuator system may comprise any number of motors, couplings, and heddle strings or wires. For instance, the actuator system may comprise at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 20, at least 30, at least 40, at least 50, at least 60, at least 70, at least 80, at least 90, at least 100, at least 200, at least 300, at least 400, at least 500, at least 600, at least 700, at least 800, at least 900, at least 1,000, at least 2,000, at least 3,000, at least 4,000, at least 5,000, at least 6,000, at least 7,000, at least 8,000, at least 9,000, or at least 10,000 motors, or a number of motors that is within a range defined by any two of the preceding values. The actuator system may comprise at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 20, at least 30, at least 40, at least 50, at least 60, at least 70, at least 80, at least 90, at least 100, at least 200, at least 300, at least 400, at least 500, at least 600, at least 700, at least 800, at least 900, at least 1,000, at least 2,000, at least 3,000, at least 4,000, at least 5,000, at least 6,000, at least 7,000, at least 8,000, at least 9,000, or at least 10,000 couplings, or a number of couplings that is within a range defined by any two of the preceding values. The actuator system may comprise at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 20, at least 30, at least 40, at least 50, at least 60, at least 70, at least 80, at least 90, at least 100, at least 200, at least 300, at least 400, at least 500, at least 600, at least 700, at least 800, at least 900, at least 1,000, at least 2,000, at least 3,000, at least 4,000, at least 5,000, at least 6,000, at least 7,000, at least 8,000, at least 9,000, or at least 10,000 heddle strings or wires, or a number of heddle strings or wires that is within a range defined by any two of the preceding values.
The actuator system may comprise any number of actuator modules, as described herein (for instance, with respect to
The actuator system described with respect to
To facilitate ease of module replacement, each of the modules may be releasably coupled to and detached from the actuator system or the loom, such as via a quick release mechanism. The quick release coupling mechanism may enable a user to rapidly mechanically and electrically couple (attach) and/or decouple (remove) each module from the actuator system or the loom with a short sequence of simple motions (such as sliding motions; rotating or twisting motions; depressing a button, switch, or plunger, etc.). A quick release coupling mechanism may require no more than one, two, three, or four user motions to perform a coupling and/or decoupling action. The quick release coupling mechanism may allow one or more modules to be coupled or decoupled manually by a user without the use of tools. The arrangement of the modules in the actuator system (or arrangement with respect to the loom) may also permit a user easy access to the modules. This can be useful, for example when a module in the actuator system needs to be repaired or replaced. In contrast, conventional actuation systems used in looms generally have a large number of actuators and controllers mechanically and electrically coupled together in a serial manner or intricate fashion, which makes it cumbersome for a user to access and replace or repair individual components.
