METHOD OF MANUFACTURING MECHANORECEPTION STIMULATION FABRIC
20220133663 · 2022-05-05 ·

A method for manufacturing a mechanoreception fabric for incorporation into a garment or item of apparel sets a liquid substrate to a fabric weave to produce a plurality of protuberances in graticulate array and spaced apart across a surface of the fabric. The plurality of protuberances includes pyramidal nodes, each independent and separate from other nodes, not less than 1 mm apart at the base and not more than 5 mm apart at each apex and 1.5 mm in height. Because the nodes are separated and not in contact with each other, the fabric produced is still stretchable and wearable when incorporated into an item of apparel despite the nodes having a hardness of between Shore A 60 and 80.

Methods and apparatuses for casting polymer products

In an example method of forming a waveguide film, a photocurable material is dispensed into a space between a first mold portion and a second mold portion opposite the first mold portion. Further, a relative separation between a surface of the first mold portion with respect to a surface of the second mold portion opposing the surface of the first mold portion is adjusted. The photocurable material in the space is irradiated with radiation suitable for photocuring the photocurable material to form a cured waveguide film. Concurrent to irradiating the photocurable material, the relative separation between the surface of the first mold portion and the surface of the second mold portion is varied and/or an intensity of the radiation irradiating the photocurable material is varied.
