HOW TO GET WHAT YOU WANT. Thermochromic inks are pigments that change color to colorless at certain temperature.

HOW TO GET WHAT YOU WANT

There are many different types of thermochromic pigments including textile inks for textile screen printing. Usually you mix normal textile pigments with thermochromic inks so that it looks like the ink is changing from one color to the other. For example, if you mix yellow normal pigment with blue thermochromic ink, you will get green ink that changes from green (under reaction temperature) to yellow (over reaction temperature). At the Swedish school of Textiles, where Mika is located at the moment, gets thermochromic inks from: Zenit The good thing about this company is that they have smaller quantity (100ml bottles) with affordable price (please ask directly to Zenit about the price list), but they have only 27 degrees reaction temperature inks.

B&G color They have wide variety of inks with reaction temperature and colors. Trifunctional Colors - Thermochromic Microcapsule, Photochromic Colorants, Thermochromic Colorants. Introduction : Dye is a substrate showing its colour by absorption & reflection of light; it is affected greatly by circumstances.

Trifunctional Colors - Thermochromic Microcapsule, Photochromic Colorants, Thermochromic Colorants

Thermochromic dyes have a characteristic whereby the colour changes according to temperature. However, because the dye (coloring matter) is very sensitive to circumstances, some shield (protection) is needed. In our Chameleon range the shield is a microcapsule. The Thermochromic microcapsule is a thermochromic colorant especially protected by the microcapsule wall. "A" loses its colour by absorption of heat, if the heat is intercepted; the coloring matter resumes its original chemical structure, and shows its own colour again. Thermochromic microcapsules are available in various colours, and they are also available with different temperature Sensitivities that affect their colour.

These products are available in a powder form for plastic extrusion and Aqueous Slurry for Textile application such as dyeing and printing. B&H Colour Change - colour change plastics, game cards, mousemats, coasters and stickers - triggered by changes in temperature, UV or moisture. Pigments for the ultimate in color changing custom paint! Thermochromics change color dramatically (even from black to white) as the temperature changes.

This pigment can be used in everything from custom paint to clothing. Our pigments have been used in everything from masks to motorcycles. Use in your own testing for a custom application! Thermochromic paints change as the temperature changes. As the temperature goes up, the pigment becomes colorless, revealing the base coat or graphics underneath. Mix these pigments with our pearls for a subtle and more protected paint job. Just mix into a clear base (like a blender or a binder) and spray it. 4 level teaspoons of our mixture per pint will get you great temperature or solar change paint at a great price.

Future Textile » Intelligent Textiles. ChromaZone. Polymer Opals. Researchers at the Cavendish laboratories, (University of Cambridge, UK) in partnership with the DKI (Deutsches Kunststoff-Institut, Darmstadt, Germany) are working on industrially scalable structural colour materials for decorative, security and sensing applications.

Polymer Opals

The Cambridge team lead by Prof. Jeremy Baumberg and Dr David Snoswell explain the technology behind these striking colour changing materials that are currently being developed for commercial release. Natural gemstone opals have long been sought after for their bright saturated colours. Study of opals reveals that the colour is produced by their internal structure causing diffraction of visible light.

The diffraction causes the enhanced reflection of particular wavelengths of light that gives rise to the very pure and intense colours so characteristic of opals. There are a number of methods to produce ordered structures with such precision. Turn LCDs into Electroluminescent Displays - Luxprint Experiments. Jon Beck - Silk Screen-able Electroluminescent Ink. Zenit AB Konsthantverksmaterial. Luminescent. Luminescent Raincoat This project juxtaposes electricity and water in a raincoat that luminesces in response to droplets of rain.

Embroidered water sensors act as inputs to a system with sealed electroluminescent panels that illuminate based on patterns of rain. The raincoat/cape and hood recall the retro-futuristic designs of Pierre Cardin and Andre Courreges in the sixties while incorporating computational behavior beyond an aesthetic notion of what technology looks like. ReSkin Emerging Technology Lab & Forum « Australian Network for Art and Technology. The reSkin wearables research and development laboratory was presented as ANAT’s Emerging Technology Lab held from 14 January – 4 February 2007 at the Australian National University.

Singing Bowl, by Sean O'Connell. Prototype developed during the reSkin lab. ANAT Emerging Technology Labs have traditionally focused on introducing the skills associated with emerging technologically based practices to a wide sector of Australian media arts practitioners, writers and curators. This lab aimed to extend the reach to include design and craft practitioners including jewellers, fashion designers and object makers. The lab brought together twenty national and international artists and designers to investigate the dynamic field of wearable technologies over a three-week intensive period. The response to the lab was overwhelmingly positive from participants, facilitators, and project partners.

Marjan Kooroshnia's Page. Temperature-Sensitive Glass. Product Details Color-changing dyes and additives have been offered in paper, plastic, and textiles for some time, but this product takes the idea into a new area: glass tiles.

Temperature-Sensitive Glass

Offered in a range of colors and sensitivities, the tiles change color based on ambient temperature, body temperature, or water temperature. The textured glass surface layer protects and highlights the color-change film on the tile. Mindsets online - Thermocolour / Thermochromic Sheet - Heat/Voltage Reactive.

Thermochromic inks from Siltech. “Thermoprint” Irreversible Colour-change Inks We offer an ink/lacquer, a “chemithermal”, which can either be coated down onto label stock to produce the familiar “thermal-label”, or can be printed down as a heat-sensitive patch on a printed label. As the surface area required for the variable information (batch-code, sell-by date, bar code), is frequently only a small proportion of the total, it will be cost effective to print this patch when the rest of the label is printed. Compared with the use of thermal label stock, the printing of a small patch of our chemithermal ink can produce much improved margins for the printer.

The normal colour change would be white to black, e.g. TFBK90 (Thermoprint, Flexo, Black, 90C), although other colours and temperatures can be offered.
