A method of manufacturing a color-changing fiber includes loading a polymeric material and a thermochromic pigment material into a fiber fabrication machine that comprises an extruder and a spinneret, operating the extruder to provide a molten mixture of the polymeric material and the thermochromic pigment material, providing a volume of the molten mixture to the spinneret, and operating the spinneret to coat an electrically conductive core with the molten mixture to form a coating layer around the electrically conductive core to produce the color-changing fiber. The polymeric material and the thermochromic pigment material are provided as (a) a first raw material comprising the polymeric material and a second raw material comprising the thermochromic pigment material or (b) a thermochromic pigment and polymer mixture.

Aspects are directed to a textile substrate with two or more ink layers and methods for printing a textile substrate. The two or more ink layers may include one or more visual components that form graphics or images that are visible to an observer when viewing the textile substrate from different angles.

[Problems] Provided is a discoloring body which is discolored by application of water and has high glossiness and is excellent in applicability to various fields such as a toy field, a decoration field, and a design field. [Solution] A discoloring body including a supporting body, a porous layer in which a low refractive index pigment is fixed in a dispersed state by way of a binder resin, and a glossy resin layer, in which an occupancy area ratio of the glossy resin layer is 1% to 95% with respect to a 1 cm square at any position in the porous layer.

The present invention relates to a monoazo-based dye for acid detection, which changes color upon addition of or exposure to acid and, more specifically, to a dye which changes color within a few seconds upon exposure to a trace amount of a strong acidic material, and a fiber product using the same. The monoazo-based dye for acid detection according to the present invention has an effect of reacting with a trace amount of strong acid to change color, and returning to the original color when the acid is removed. Also, a fiber dyed with the dye of the present invention exhibits high color fastness and thus is not discolored and faded by laundering or sunlight. In addition, there is an effect of preventing secondary contamination at an accident scene and serious accidents from harmful environmental factors, when protective or working clothes are manufactured applying the effect, thereby providing a function enabling workers to recognize an exposure to acid in real time in the case of an exposure to an acid-contaminated environment.

An article includes a substrate with a surface, and a coating disposed over the surface. The coating includes a binder material and a plurality of UV scattering porous polymer particles having pores with a light scattering effective pore size of no more than 100 nm. The coating has a scattering opacity of no more than 20% in the wavelength band from 500 to 3000 nm.

A nonwoven wipe having a reversible sanitizer indicator for multiple uses and recharges is provided. The nonwoven wipe includes a cloth-like nonwoven fabric coated with a reversible color-changing ink formulation. During use, the nonwoven wipe is impregnated with a quaternary ammonium compound-based sanitizer. When the level of free quaternary ammonium compound falls below a threshold level, the color-changing ink formulation changes from a first color to a second color, indicating the need to recharge the wipe. When the nonwoven wipe is recharged with sanitizer solution, the color-changing ink formulation changes back to the first color.

Embodiments provide thermochromic articles of apparel and methods of production. The article of apparel may comprise a textile layer and a thermochromic portion that includes at least one set of thermochromic molecules that affixed to the textile layer. A heat protective layer may be positioned on a first surface of the thermochromic portion.

Exciting and flashy images are created on a garment with a method that includes the steps of selecting a stretch fabric having a front side and a back side. A front side of the fabric is dyed with a solid color. A back side of the fabric is dyed with a knock out image. The knock out image is visible when the stretch fabric is stretched and is not visible when the stretch fabric is in a relaxed state. In one case, the fabric is part of jersey and when the player stretches the fabric an image becomes visible. In another case, the image expands or seems to glow. This provides a dynamic flashy image that is exciting to advertisers and fans alike.

A system for treatment of thread includes a weft thread printer having an intake positioned to receive a weft thread from a source, as well as an encoder that is configured to detect a length of the weft thread as the weft thread moves through the weft thread printer along a travel path. The system also includes a printhead positioned to apply coatings of a plurality of colors to the weft thread and yield a treated weft thread, as well as an outlet positioned to pass the treated weft thread to a loom.

The composition and method for depositing and processing a solid transparent electrolyte polymerized by ultraviolet (UV) radiation are described. The electrolyte composition includes, at least, an ionic compound, a polymerizable material, a photoinitiator and a polar solvent. The electrolyte is deposited by printing techniques, such as inkjet printing.
