  • One form of knit structure used has been the“mesh-matrix” structure which is created by various geometries of squares, hexagons and circles that create a mesh-matrix which can be either active or non-active fiber/yams, wherein the voids in the shapes are filled with the complementary yarn (non-active or active respectively). In some cases this may be spun fibers or monofilaments that create the mesh-matrix, and the filled voids are created by using short / dropped rows or yarn floats. This results in either compression of the void area where the material protrudes orthogonal to the plane increasing material thickness, or by stretching the void to cause the knit structure to become more porous.

  • the individual active fibers 111 can be formed of a single active fiber 111, which has been looped around in the stitching pattern.

  • Plain stitches 130 are formed among the active fibers 111, among the active fibers 111 and inactive fibers 121, and among the inactive fibers 121. While the stitches 130 illustrated in FIG. 13C are jersey stitches, a wide variety of stitches are suitable.
  • a set of horizontal floats 140 is formed of a plurality of individual horizontal floats 141 of the inactive fibers 121. In some cases, there is only one horizontal float 141. Across the set of horizontal floats 140, an elongated loop (held stitch) 150 is formed in the active fiber. As illustrated in FIG. 3C, there are two sets of active fibers 110, but more can be included. FIG. 3C illustrates eight floats 141 of the inactive fibers, but more or less can be included. More floats produces a greater transformation than fewer floats.
  • a textile can include one or more regions of active fibers that overlie (or underlie) one or more floats 241 of inactive fibers 221.

  • plating which is achieved by using machine knitting to create a face and back to the knit structure of two different materials. This results in a planar shape change that causes curling as one face expands or contracts relative to the other face. The direction of this can be alternated to create an undulating surface or cause a curl along the x axis due to heat and the y-axis due to moisture.
  • FIG. 15C Another example is FIG. 15C, where active fibers 311 are stitched with inactive fibers 321. As illustrated, an active fiber 311 is stitched in an alternating pattern, by forming a back tuck 311a followed by a front stitch 31 lb.

  • a wide variety of alternatives patterns can be stitched, and the stitching need not be in rigid patterns. In some instances, adjacent columns of stitches can be identical; in some instances, adjacent columns of stitches need not be identical.
  • Alternation of simple knit structures (e.g. jersey) in active and non-active material can cause an accordion-like structure that expands or contracts based on temperature or moisture. Tessellation of triangles, trapezoids, rectangles and other shapes can create a similar effect.
  • the type, amount and location of the applied activation energy to the active textile can create different transformation characteristics based on the pattern and amount of active material.
  • the textile material without the active fiber should not respond to the heat, only the heat-active fibers will cause local transformation based on the structure of the knit and amount of active fibers. If the entire textile structure is created with heat-active fibers, the entire textile or zone may transform. However, if the heat is applied in a precise and local pattern, then a smaller local transformation may occur. This demonstrates that the location of the applied energy has a direct impact on the type of transformation. Similarly, the amount of activation will cause different transformation characteristics. For example, if more heat is applied in a short amount of time it may speed up the transformation, depending on the active material’s characteristics.
  • the location and type of active material based on the supplied activation energy allows for many different transformations with different activations energies, at different times and should be designed specifically for the application and environment of use.
  • Robotic activation of the garment is intended to translate or“program” a garment with a specific conformational response based on aesthetic design, comfort/fit, functional output or user-body mapping.
  • Robotic activation can be any computer-numerically controlled process that allows the application of activation energy (heat, moisture, light etc.) in a controlled fashion. This can include light activation or controlled moisture or heat application through some combination of heat/moisture source that moves relative to the garment. This movement can be controlled using a 5-axis robotic arm and/or turntable that moves the heat/moisture source in a defined 3D path over the garment. This can either be a raster or vector process for translating the information map to the garment.
  • activation energy heat, moisture, light etc.
  • This movement can be controlled using a 5-axis robotic arm and/or turntable that moves the heat/moisture source in a defined 3D path over the garment. This can either be a raster or vector process for translating the information map to the garment.
  • Activation can also be achieved, particularly for uniform shape or zonal change rather than porosity change, by having the user wear the garment in an environmental chamber with controllable moisture or heat that is comfortable for the wearer but exceeds the activation range.
  • a unique geometry can be conformed to the wearer, or body-mapping of the wear can be translated into a knit program unique to the wearer and pre knit into the garment that is then finally“set” once exposed to the activation temperature / Rh% level.
  • Amplitude of the activation energy can either be controlled at the source or by varying the robotic path. Varying relative distance and speed to the garment enables fast control of the dynamic range of the activation energy source, as in the example of a heat gun, the latency of heating elements to heat up or down is much longer than the drop off in energy exposure due to (Relative Distance) A (-2).
  • This activation can be formed on a molded mannequin or the user depending on the activation energy.
  • the knit textile can contains zones with different material compositions or knit structures that amplify or constraint the types of transformations. This zonal design can be created based on the specific user or more genetically designed for different regions of any garment.
  • the textiles allow for precise control over transformations in a textile garment - either uniformly across the garment or applied in specific zones for variable transformation based on the user’s preferences. This method produces predictable and precise
  • custom/personalized fit and styling and perfect tailoring This could be achieved with standard sized - s, m, 1, xl - and then post-activated on the body or this could be created with custom knit structures that are activated in a uniform manner within an environmental chamber.
  • Body-mapping of the individual can be translated into a garment that has a controlled distance between the skin and the garment to create“the perfect fit” - and gives control that is not possible with 2-D construction techniques.
  • controlled activation paths enable aesthetic structures that give a unique look that can be personalized to the wearer.
  • This personalized garment can be tailored to a person’s style or aesthetic preferences as well as individualized comfort profiles.
  • Compression and shape constraint or flexibility/mobility can be achieved by following paths that are unique to the user's biomechanics, gait etc. This can create structures that aren’t possible due to the limitations of traditional 2-dimensional garment construction. For example, compression tights that provide mobility at the knee, localized to the wearers geometry, but compression in the thigh and calf, while also providing gradual compression to facilitate blood flow. 4.3 Body-Mapped Moisture/Heat Ventilated Garments
  • An application of this process may include the translation of thermal body mapping to a personalized garment that reflects the user’s unique heat signature thereby allocating the right knit structure in the right zone. Closed or open pores, or active and non active regions can be controlled based on the thermal and moisture variability of different areas of the user’s skin surface.
  • This textiles offer significant advantages over traditional methods of tailoring.
  • garments are either produced with standard sizes (S, M, L) or at the high-end, they are manually tailored to fit an individual.
  • manual tailoring is labor intensive, expensive, and time consuming which often makes it difficult for everyday clothes, customers or businesses to realize.
  • manual tailoring often has a limited number of techniques for adjusting a garment - hem, tuck etc.
  • the garment can adapt and transform on its own without manual tailoring, reducing the cost/complexity/time needed to have customized garments for every user.
  • the active textile garment can adapt in complex, intricate and nuanced ways that would be difficult or impossible to manually tailor. This allows the garment to adapt to the curvature, size and uniqueness of everyone's individual body or comfort preferences.
