In various aspects, the present disclosure relates to fibers and fabric media comprising photoactivatable agents and to fibers and fabric media that are photoactivatable by photoactivation of the photoactivatable agents. In some instances, the fibers and the fabric media have photoactivatable agents present on their surface (e.g., the fiber/fabric is coated or sprayed with the photoactivatable agents or the fiber/fabric is dipped into a composition or a formulation comprising the photoactivatable agent). In other instances, the photoactivatable agents are incorporated into the materials making the fibers (e.g., the photoactivatable agents are mixed/compounded with the materials making the fibers). The photoactivatable fibers of the present disclosure comprise at least one thermoplastic polymer and at least photoactivatable agent that absorbs and emits light between about 400 nm and about 800 nm.

An image transfer article can include an image-imparting member and a removable substrate disposed adjacent to the image-imparting member. The image-imparting member can have a softening point temperature less than about 220° C. The image-imparting member can include at least one surface configured to receive and carry indicia to be transferred and at least one portion comprising a pigment providing an opaque background for received indicia. In some examples, the image-imparting member can comprise a first polymer including the indicia and at least a second polymer including the pigment. In some examples, the image-imparting member can comprise a polymer including the indicia and the pigment. The indicia and the opaque background can be arranged to concurrently transfer to a woven- or fabric-based article or paper in contact with the image-imparting member, upon application of iron pressing temperatures.

A complex or composition of a photosensitizer associated with an inclusion complex former for use in forming active surfaces and active materials to kill or render inactive pathogens. A composition having photosensitizer associated with an inclusion complex former, a nanoparticle and liquid. Treating a material, such as a fabric, fiber, product, surface, woven, and non-woven with a photosensitizer and nanoparticle whereby treated material is an active surface that kills or renders inactive pathogens upon illumination with sufficient light.

An example dye sublimation inkjet ink set includes a first dye sublimation inkjet ink and a second dye sublimation inkjet ink. The first dye sublimation inkjet ink includes a disperse dye colorant dispersion including a first disperse dye having absorption at a radiation wavelength ranging from about 360 nm to about 410 nm; an additive to absorb energy at the radiation wavelength ranging from about 360 nm to about 410 nm and to dissipate at least some of the absorbed energy as fluorescence; a co-solvent; and a balance of water. The additive is selected from the group consisting of a compound containing from 3 to 5 fused benzene rings and and a coumarin derivative. The second dye sublimation inkjet ink includes a disperse dye colorant dispersion including a second disperse dye having less absorption at the radiation wavelength than the first disperse dye; a co-solvent; and a balance of water.

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.

A biopolymer composition can be formed based, at least in part, on a recombinantly expressed protein, expressed from a DNA coding sequence of a source protein, and the recombinantly expressed protein can optionally comprise one or more tags that enhance the crosslinking capacity of the protein. It was determined that such biopolymer composition can be suitable for use to obtain, for example, a biodegradable textile that exhibits a functional characteristic associated with the recombinantly expressed protein.

Casings, dye tablets, DIY activity-kits include one or more casings, one or more encased dye tablets, or a combination thereof, that are configured to impart an artistic effect to an article, hydrographic sheets, and dip and decorator activity-kits including one or more hydrographic sheets and an instruction for imparting an artistic effect to the article using the one or more hydrographic sheets. The casings include at least one compartment formed of a water-soluble film, and one or more agents disposed within the at least one compartment. The encased dye tablet includes one or more agents compounded with a filler and a binder. The one or more agents include at least one colorant formulation and at least one fixative.

The present invention relates to a fabric containing a modacrylic fiber A and a cellulosic fiber, wherein the modacrylic fiber A contains an infrared absorber inside the fiber, and the fabric is dyed with at least a yellow cationic dye, a yellow reactive dye, and a yellow disperse dye. The fabric can be produced by dyeing a fabric containing a modacrylic fiber A and a cellulosic fiber with a cationic dye, a reactive dye, and a disperse dye to exhibit a fluorescent yellow color. Accordingly, it is possible to provide a fabric with excellent arc resistance and visibility, a method for producing the same, and a clothing item using the same.

Compounds for use in the textile field, and more particularly the use of compounds of the 4-bora-3a,4a-diaza-s-indacene family for the manufacture of fluorescent fibers, the fluorescent compound being chosen from those of formula I: ##STR00001##
Also, processes for producing the fluorescent fibers and also to the uses thereof, notably for the provision of security to products.

A method of using an automated system to position a fabric piece. A pattern is printed onto a fabric piece with fluorescent ink, and detected with a fluorescence-detecting camera, such as a UV camera. The detected pattern is stored in a controller as a pattern signature and compared to a stored target pattern. The results of the comparing step are used to generate control signals for the automated system to move the piece into the position of the target pattern.
