Americos Thermochromic Microcapsule

Introduction :
Dye is a substrate showing its colour by absorption & reflection of light; it is affected greatly by circumstances. 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. Colours available are: Black, Blue, Violet, Rose red, Red and Orange.



These products are available in a powder form for plastic extrusion and Aqueous Slurry for Textile application such as dyeing and printing.

Temperature change ranges are 7°C, 15°C, 25°C, and 31°C

Introduction :
Americos Photochromic colors are plastisol based inks, which are off-white when not exposed to UV radiation. It gains colour when exposed to Sun light / UV light. The color change is "reversible," i.e., the color will fade again and appear colour less upon removal from UV light / sun light exposure. These inks are available in various colors. See our colour availability chart for a complete list of available colors.

The uses of Americos Photochromic colors are:

• On garment to create novel products and promotional items like T-shirts
• On fabric/garment to print company logo / brand name to prevent duplication
• On garment which are used for party wear
• Thermometers and temperature indicators
• Security printing
• Food industry to indicate temperature of packaged food

Properties:

Viscosity (at 25º C)	100-150 poise
Density (Approx.)	9.0 lbs/gal
Appearance	off-white paste
Percent solids	100%
Percent volatile	Negligible
Recommended Substrates	Textiles

Application of Photochromic color on garments:
Americos Photochromic textile colors changes color with changes in light intensity. They print and cure as easily as other plastisol inks. They will not chock your screen and do not contain any solvents. They may be printed on 100% cotton synthetic/cotton blends

Americos Photochromic colors are plastisol based ready to use off-white liquid. When exposed to UV radiation, colour appears. These inks are available in various hues.

Photochromic colour can be applied on garment by three methods:

• Spray
• Brush
• Screen Printing

In all above methods, Photochromic colour is directly applied on garment and cured at 150^oC for 30 - 90 seconds.

Special Care Instruction:
Americos Photochromic colors should be printed on white or light colors. The following suggestions should be kept in mind when running the thermo-chromic colour.

• Recommended screen mesh: 130 - 200 mesh count with 150 preferred.
• Deposit thickness: 1 - 3 mils
• Curing: 155°-160ºC for 30 - 90 seconds (colour should not be over-cured

Note: Residual color may be a problem with colorless to color inks. This can be controlled by putting down a thinner film, though this may affect color intensity as well. Residual color can also become a problem if too much heat is used in drying the inks.

Americos Glow in Dark Colorants is a blended mineral compound that responds quickly to excitation by daylight, incandescent, fluorescent or ultraviolet light. This pigment emits a bright phosphorescence shade. It exhibits high initial brightness and long afterglow, up to 2 hours. The afterglow effect is dependent on pigment concentration, surface area and amount of radiant energy absorbed.

The uses of Americos Glow in Dark Colorants are:

• On garment to create novel products and promotional items like T-shirts, which are used in disco parties
• On fabric/garment to print company logo / brand name to prevent duplication
• On garments which are used for party Americos Glow in Dark Colorants can be mixed with certain transparent pigments or colorants such as fluorescent dyes and pigments. This combination will achieve some very attractive special effects

Properties:

Emission Color	Green
Body color	White/Green
Specific Gravity	4.0 g/cc

Application of Americos Glow in Dark Colorants on garment:
Americos Glow - in - Dark colour can be applied on garment by three methods

• Spray
• Brush
• Screen Printing

In all above methods, Glow - in - Dark colour is directly applied on garment and cured at 150^oC for 5 minutes.

Precautions:
When handling Americos Glow - in - Dark colour, some precautions should be taken when:

• Avoid working with strong acids since this can cause dissolution of phosphorescent pigments.
• In the presence of high relative humidity and sunlight, phosphorescent pigments can exhibit darkening.
• In the presence of metal ions, phosphorescent pigments can lose their ability to glow.
• The addition of colorless extenders or colored pigments will reduce the intensity of the phosphorescence (afterglow effect)
• Testing is recommended in the intended application to determine suitability.

Introduction :
Americos Trifunctional Colors are specially designed for garment industry to get cloudy effect on garment. This effect resembles the tie & dye effect but the approach is totally different. In this technology, garments are first dyed with tri-functional colors in garment dyeing m/c. Then the dyed garments are tied with thread at different parts according to the design to be formed on garment. Then it is treated with Americos Deni XL solution (discharger) and subsequently with Americos Deni OX (neutralizer). Thus, this method opens unlimited doors for developing creative designs on garments. Using this technology, garment processors can achieve cloudy effect of more than two colors from one trifunctional color. It saves labor, water and energy involved in traditional process of tie & dye.

The whole process is divided in to four steps:

Dyeing of Garment with Americos Trifunctional Colors :

First, dyeing of garment is carried out with Americos Trifunctional color in wash wheel.

Take required amount of Americos Trifunctional Color (X g) and prepare the dye bath by dissolving the color in water. Introduce the garments in the dye bath and run the machine for 5 min. Then add 50 g/l of Glauber's salt and raise the temperature to 70 to 75°C while continuing the dyeing for 15 min. Then add 20 g/l of soda ash and continue the dyeing for another 30 min.

One cold wash - Soaping (with neutral detergent to remove unfix colors) - One hot wash - drying of garments.

Please note that generally 2 - 4% color (owf) gives good effect.

2. Tie the garment at different parts :

• After drying of the dyed garments, the garments should be tightly tied with treads at different location as per the required design/effect to be produced.

3. Discharging of Americos Trifunctional Colors with Americos Deni XL

• This is the critical and most important process. Put the garment in Americos Deni XL solution (50% w/w) or potassium permanganate (130 g/l) for few seconds (5 - 10 seconds) and take out garment from Americos Deni XL bath very fast and swiftly.

4. Neutralization of garment with Americos Deni OX

• Dip the garments, from the above process (after discharging), in Americos Deni OX solution (15 g/l) and keep the garments immersed for 5 - 10 min. Then wash the garments with water.
