The present invention provides a post-fabrication modification approach for the fabrication of colored and chromic materials and sensors using plasma surface modification to covalently bind the coloring agent to the substrate, thus avoiding leaching of the dye. Advantageously, in said methods, said coloring agent is a dye or pigment linked to a radical sensitive functional group, such as an alkenyl or alkynyl functional group, and is applied to the substrate prior to the gas plasma treatment. The methods envisaged herein are generic in nature, which allow the covalent immobilization of various dyes on different materials. The covalently coated materials after plasma surface modification, particularly the covalently coated chromic materials and sensors, can be used in many different applications, such as protective textile and wound dressing applications.

A method of treating leather or hide is provided whereby a biocide and one or more detectable tags are applied to a piece of leather or hide. The detectable tag(s) can be detected to indicate one or more pieces of information, such as that the biocide has been applied to the piece of leather or hide and/or other information. Information about the biocide and the tannery that applied the biocide or other information can be discerned from detecting the detectable tag or from one or more of the detectable tags if used. A system for tagging leather or hide and applying a biocide are also provided as are methods and systems for detecting the tags.

A method for manufacturing long lasting phosphorescent fabrics and articles of clothing including fabric for use in fields such as security, domestic, sports, health, professional, etc., includes (i) preparing a composition for dyeing having a strontium aluminate pigment doped with europium and dysprosium; (ii) coating a starting fabric with the composition by air knife coating or cylinder; (iii) drying; and (iv) polymerizing. The fabrics thus obtained have long lasting phosphorescent properties and a high resistance to washing, maintaining the factory specifications of the starting fabric with respect to its mechanical properties, comfort, breathability and/or high visibility properties, if relevant.

A high-visibility fabric according to the present invention is a fabric that is colored and includes, on at least one surface, a colored part that is colored by an application of a fluorescent-pigment-containing resin. The fluorescent-pigment-containing resin is applied to at least an entire outer surface of the colored part, and the colored part has a color that meets requirements of 5.1 Color performance requirements of new material and 5.2 Color after Xenon test of ISO 20471:2013.

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.

Provided is a flame-retardant fabric having a color that satisfies the criteria required by the international standard for high visibility ISO20471. The fabric includes polyetherimide-based fibers that contain a white pigment.

A composition, method and kit for producing reversibly dyed soft contact lenses is disclosed. The contact lenses are submerged in saline solution and a dye is added to the saline solution, either directly or by means of a strip that has been impregnated with the dye. After a period of time, the lens absorbs the dye and can be removed from the solution and placed on the eye. Once the lens is illuminated with ultraviolet light, it will glow or fluoresce. An eye having the soft contact lens applied to a cornea thereof is examined under a luminescent radiation stored in the soft contact lens. The dyeing method does not utilize heat and thus is reversible. Soaking the lens in additional saline solution for a period of time will cause the dye to return to its non-dyed state. A stabilizing compound and a method of stabilization are also disclosed herein.

Provided is a method of manufacturing a mechanoluminescent fiber. The method includes the steps of: preparing an elastic fiber having a longitudinal groove on the surface thereof; forming a primer layer including a coupling agent on the elastic fiber; filling the groove of the elastic fiber with a mixture of a stress transfer substance and a stress luminescent substance; and forming a silicon adhesive layer on the elastic fiber of which the groove is filled with the mixture of a stress transfer substance and a stress luminescent substance. The silicon adhesive layer is 3-dimensionally bonded to the elastic fiber and the mixture of a stress transfer substance and a stress luminescent substance.

An improved composition for protecting a vehicle, building, or airplane surface that will be painted or mechanically processed. For example, certain regions of a vehicle, building, or airplane may be masked in accordance with the present disclosure to protect those regions from paint overspray. The composition produces a film which adheres well to a surface to be protected, with few or no pinholes. Additionally, the composition can absorb any oil or grease present on the surface which can eliminate the need for towels and chemical solvents that may create toxic fumes, hazardous waste, and flammable hazards. Further, the material can be removed easily from the surface after use by peeling the film layer away from the surface.
