Thermal Transfer Technology and Application Solutions (1-10)

The common textile transfer technology is film transfer and sublimation transfer.

1.Sublimation transfer: The current technology is mainly applicable to clothes whose surface is polyester, such as fast-sweat shirts and physical comfort shirts, and white clothes are the best (printing patterns are white, but clothes The other parts can be other colors, such as color sleeves. After the colored clothes are sublimated digitally, the fusion of ink and colored fibers will make the colors of the patterns different from the original. It is not recommended to use them.
2. Film transfer: The current technology is mainly used for clothes with extremely high cotton content. All kinds of colors can be transferred by film, but darker clothes use higher-priced "special transfer paper for dark clothes", which is heavier in quality and less stable in quality.

2, why thermal transfer ink to use EPSON inkjet printer Caixing

Because the EPSON machine's ink jet method is piezoelectric printing, it is through the computer control to change the size of the print head micro-piezoelectric ceramic plate to make different pressures to eject ink from the nozzle to form a different shade of image; other models For example, the CANON printer belongs to the thermal foaming principle. It prints on the paper the ink that forms the ink with high temperature and pressure by heating.

Piezoelectric printers can be widely used in the thermal transfer industry because they do not change the mechanical properties of the dye-sublimation inks by changing the mechanical pressure; if the thermal sublimation ink passes through a high-temperature, high-pressure thermal foaming printer, its chemical composition will occur. Changes, the printed paper can not be thermal transfer or serious color cast, it can not be used.

3, ceramics, metal products transfer technology

Ceramic products are dye-sublimation-transferred and sublimate to the merchandise at a high temperature of approximately 200 degrees Celsius. The color is sharp and the pattern is highly reliable. However, the general mug cannot be directly transferred, and the pattern must be transferred after a special treatment of coating.

4, using an electric iron for thermal transfer method

Due to the limitation of the calorific value of the electric iron, it is generally not possible to transfer an item with an A4 size (approximately 20 x 30 cm or more). The electric iron must be able to adjust, and the greater the power, the better.

1. First adjust the iron to the cotton fabric (that is, about 170-190°C), and warm it up until the heat indicator light is on;
2. Put the clothes flat on the ironing board, use the iron on the part to be printed for a few seconds to remove the moisture;
3. The transfer paper is printed on the printing surface with the print surface facing downwards, and the four corners of the paper are prevented from moving with the adhesive.
4. Lay high temperature resistant flexible asbestos cloth on the garment with good transfer paper, and level it with four clips on the edge of the ironing board;
5. Use the iron slowly and slowly for a period of 20-30 seconds at the place where the heat transfer cloth has the transfer paper, depending on the size of the pattern;
6. When the transfer paper is not cooled, remove it from the clothing, otherwise it will stick.

5, T-shirts and cotton textiles after the maintenance of the transfer method

1. The T-shirt with the film transfer will have a hard feeling and you will become softer after washing.
2. Newly processed T-shirts should be washed after 2 hours. Turn clothes over to wash.
3. Do not rub the surface of the T-shirt pattern by hand (the material of the pattern surface will not be attached with dirt).
4. Do not wash with detergent containing bleach.
5. Wash with warm water or cold water below 40°C.
6. Try not to wash with a washing machine.
7. After washing, do not dry it with a clothes dryer.
8. To dry naturally, do not twist clothes, do not expose T-shirts to the sun.
9. If the clothes need ironing, after drying, use medium-temperature steam ironing (not including high-temperature ironing of elastic fibers, so as not to damage the structure of elastic fibers, affect the elastic effect of the clothes), and do not iron directly on the pattern.
10. After ironing, do not tuck into the narrow spaces. Hang them on hangers or spread them flat to keep them flat.

6, T-shirt transfer paper usage

1. Light-colored film thermal transfer paper Usage: Mirror the pattern, cut off the blank part of the image, print side down on the parts that need to be transferred, such as clothes and pillowcases, and coat the surface with a layer of high-temperature asbestos release paper. Heating with a tablet or iron, the transfer paper can be removed before it is cooled.
2. Dark film transfer paper usage: print the front of the pattern, peel off the back side of the front side (print side) and put it on the part that needs to be transferred. After laying the high temperature separation paper, use a flatbed to heat it. Note: There are currently dark T-shirt transfer papers with mirror-printing on plastic transfer paper.
3. Permeation dye sublimation transfer paper Usage: A, first fixative (prevent corrosion of ink by chemical detergent, prolong fade time, it is recommended to use) After shaking uniform, use a little finger pressure spray can spray on T-shirt need to turn The printed part is air-opened or dried; B. The pattern is mirror printed on the smooth side of the T-shirt paper with sublimation ink, and the tablet is heated to 180-200°C; C. The T-shirt paper is printed to face the cotton. Part of the transfer of quality clothes, press the tablet machine for 20-25 seconds (some tablet machine heating plate is not equipped with high-temperature cloth, preferably a layer, play a protective role), after the completion of the transfer, the basic T-shirt transfer paper It is better not to leave ink marks on it. (Please use a high temperature cloth in the middle of the cotton T-shirt, otherwise the ink will penetrate the back of the clothes)

7, T-shirt transfer paper and sublimation two ways that effect is good?

After transferring with a thermal transfer ink, the pattern is printed on plain paper, and the pattern can be transferred by spraying a modifier on the ordinary cotton T-shirt that needs to be transferred. The chemical fiber fabric can be directly sublimated and transferred ( 180 degrees 30 seconds). T-shirt transfer paper can be transferred with ordinary ink. With the popularization and price reduction of sublimation ink, many people now use thermal sublimation ink to print plastic film T-shirt transfer paper, but the T-shirt transfer paper The effect is not good for thermal transfer, but sublimation transfer cannot do dark clothes.

8, how to carry a cotton T-shirt transfer?

Chemical fiber or blended light-colored garments containing less than 70% cotton can be directly transferred by thermal sublimation. The breathability is free from the hand. The image and overall effect are better than any imported film transfer paper, and the price is cheaper. For 100% cotton, the modifier was previously used, which is cumbersome to use and tends to yellow when heated. It is now suggested that you can use thermal sublimation special paper with cotton textile fixing agent to transfer, but it is still a little troublesome, it is best to use low-cotton blended T-shirt for processing, fast and good, heating time to 40 seconds or more. Dark clothes can only be transferred with adhesive film.

There are also problems with the yellowing of cotton T-shirts. Many users do not complain that the ink is not good, that is, the transfer paper is not good, or there is a problem with the fixing agent. Actually, the textile printing and dyeing process and raw materials are different, he chose the kind of cloth. Can not withstand the high temperature of 180 degrees, you can use the tablet directly with a 200 degree heating test, not yellow can be used.

9, the temperature of the thermal transfer baking time

Generally speaking, the temperature can be transferred between 170-200°C, the baking time and the area of ​​the printing pattern, the coating used, the ink, the transfer paper, the ambient temperature and the humidity all have different effects. There is no absolute formula to check. The higher the temperature, the shorter the time required. The time range is within 30-100 seconds. It should be noted that the time for printing with transfer paper and regular ink should not exceed 40 seconds.

The other one, do not apply the hard copy of the so-called print time temperature table provided by some companies, and do not completely believe in your own eyes (that is, the temperature indicated by the temperature control table is the actual temperature of the sublimation ink). , temperature control table has 1-2 °C error is normal (I tested the temperature control table measured normal body temperature measured 39 °C, the boiling water temperature was measured as 102 °C); there is temperature measuring electric wire buried in the heating pad The difference in location also caused inconsistent temperature measurements, some separated by a layer of glass fiber cloth, and some separated by two layers, which can even cause differences of 10-20 °C. The experienced chef can smell the burnt smell of the paper with his nose to know if it is baked or not.
