Product Features:
Product features: light, shading power, excellent adhesion, low temperature heating, the surface does not stick back
1. Product appearance: was paste, storage stability, thixotropy is small, easy to stick when placed, stirring and printing is not easy to dilute, you can maintain a certain viscosity, three-dimensional effect is good, heat treatment will not change because of the high temperature Into a rounded corner.
2. Because the heat-solid ink does not contain solvent, the amount of volatile at room temperature is extremely small, heated to a certain temperature, the occurrence of cross-linking reaction and curing, so at room temperature will not dry, do not plug network, get off work without washing version, you can use 350 Head printing, cable up to 80 lines or more --- fine pattern, printing network when wet wet wet continuous printing, can improve work efficiency.
3. With elasticity, adhesion fastness up to wet wash 5, dry wipe more than 4.
4. Dark, light-colored fabric can be printed.
5. Variety of species, can be printed many three-dimensional right angle, rounded corners, stone effects and other special products.
Scope of application:
Applicable to 100% cotton, cotton / polyester blended, polyester, dark light cloth, denim and other fabrics, where the following two fabrics can be used:
1, capable of 150 ° C;
2, a breathable, you can make ink penetration into.
Not suitable for substrates such as plastic, metal, glass and water treatment of nylon cloth.
Heat treatment:
Use must be heat treatment, heating resin absorption around the plasticizer, and glue into the film, at 80-120 ° C began to glue, called semi-drying or flash baking, the purpose is to non-stick version. In the sudden temperature that is 140-160 ° C under the full drying, only full baking, in order to make the ink thoroughly dry curing! The effect of heat treatment is very important, almost 90% of the problems are related to baking. Note the following:
1. Treatment is not enough to affect the fastness, when the ink will fall off the water, the elasticity is not easy to be pulled off the crack.
2. Must be in the appropriate temperature, in order to make the ink film fully formed.
3. Measure the temperature of the baked ink, not the temperature of the device.
4. Heat absorption is a process, determined by the temperature and time factors, the temperature is high, the temperature is low, the time required is longer, but can not be lower than the lowest polymerization temperature. Usually in order to speed up the temperature selection at 160-165 ° C instead of 140 ° C.
5. Film thicker, the surface and inside the degree of baking different, need to extend the time, especially in the printed version of the effect.
6. white clothing due to the reflection time to be lengthened, and black clothing heat, heating time can be appropriately reduced due to different colors and different heat absorption of the fabric, the heating time can be adjusted accordingly.
7. The best use of infrared heating equipment, because the infrared penetration, the ink can be low-level drying.
Operational guidelines: (a) printing methods
1.PLASTISOL ink is a major feature of fine grain can be printed fine pattern. So only the appropriate film, in order to make ink to play its advantages. So it is best to use a special hot ink for the printing of the film, the gradient color, copy the time to pay attention not to lose outlets.
2. The choice of mesh is also very important, different colors of the mesh is sometimes different, different colors of clothes, mesh requirements are not the same, in general, dark clothes mesh size will be smaller. Recommended mesh:
* Four-color effect: 250-350 mesh * Network effect: 160-250 head
* High cover real color ink / foam: 100-150 mesh * gold and silver powder effect: 80-120 head
* Onion effect: 30-40 mesh * Stereo effect: 80-100 mesh
3. For different ingredients (cotton, chemical fiber), different colors of fabric, feel, color requirements or want to achieve special effects, to select the appropriate ink series, or add different additives. For example: to print four-color reduction effect, should choose the four primary colors series; dark clothes can be used high hiding ink or playing white; TC material to prevent the dispersion of dyes in the fabric bleaching phenomenon, it is best to use sublimation The
4. Printing order: light-colored clothing light-dark (continuous printing) - drying 160 ° C dark clothing white - 120-140 ° C baking to semi-dry - continuous printing - drying As above
5. Scraper hardness: 70 degrees, angle: 40-60 degrees, the gap between the frame and the board: 0.2-0.5CM, four-color thermal ink printing can be used 70 degrees, high cover ink can reduce the scraper hardness 60-65 degrees The
Operational guidelines: (b) the required equipment
1. Automatic printing machine or walk Taiwan. Automatic printing machine is better than manual, but the investment is greater.
2. Drying equipment: infrared dryer. Generally need two kinds, one is in line with the printing process of semi-drying (flash baking) infrared oven, walk Taiwan can use the table dryer, many factories use hot air gun. Brother two are: conveyor tunnel tunnel infrared dryer, for the final thorough drying treatment, the length of choice is about 6-8 meters over 2-3 minutes.
Operation guidelines: (c) the use of precautions
1. Use of diluent: PLASTISOL for the paste, to stir and then decide whether to add thinner. Under normal circumstances can be used after mixing.
2. The amount of each additive can not be too much, because Canada may damage the original ink system balance, causing other problems. Such as fastness, bleed, discoloration, elasticity, hiding power and other changes in nature.
3. Non-contact printing, frame and platen to have a distance of 0.2-0.8cm.
4. Different series of ink in the mixed use, to take into account the changes after mixing, such as hiding power, feel, brightness and so on.
Operational guidelines: (d) special effects of the printing method
1. Spot color line: in the use of color separation software color separation, with 5-12 color can be printed with a special texture of the photo effect, and in dark, light-colored cloth printed on the general use of 160 head - 200 mesh screen version, cable about 35-50 lines, flat angle scraper.
2. Four-color screen: in the correct use of mesh mesh and the number of lines and the angle of the case, the light cloth or in the dark cloth after playing the white background to print a fine photo effect pictorial ; Generally with 200 mesh -350 mesh, 50-80 lines, medium hardness flat angle scraper.
3. Three-dimensional fillet: the use of three-dimensional aerosol ink, thick film with a thick film printing, the first pass to force ink to ensure that the ink into the fabric fiber, the second time later to ensure uniform force, just to ink off In the screen, such a fillet surface smooth, good fastness. Generally available mesh for 80-120 mesh, scraper to be softer, about 60 degrees.
4. Three-dimensional right angle: the use of three-dimensional right-angle ink, only the use of ordinary photoresist produced slightly thicker than the general version of the screen, pay attention to the same time and fillet. Drying attention to control the appropriate temperature, to dry but not too high temperature, otherwise it will destroy the effect of its three-dimensional at right angles.
Operational guidelines: (5) Test methods for heat treatment
1. Tensile test: printed hot solid ink should have a better flexibility, stretching 50% should be kept well.
2. hand scratch test: hand light scraping, without any powder or paste off the phenomenon.
3. Wipe with white cloth or white paper to see if there is any color.
4. Washing test: 80 ° C warm water and laundry with the same detergent cycle 3-5 times washing, drying process, without any damage.
5. From the surface observation: baked will have a bright effect.
6. Touch by hand, soaking the thermosetting than not brittle more tough.
Operational guidelines: (c) how to control the transfer of ink, cloth sublimation of the phenomenon
1. If the ink appears ink transfer or fabric color sublimation instructions First of all to improve the consistency of ink, adding thickening additives can be improved.
2. Do not bake too much.
3. First printed at the end of white, especially with anti-sublimation of the end of white, fast drying the surface, and then printed other colors.
4. Use the appropriate fabric or dye, usually chemical fiber used in the dispersion of dyes, easy to sublimation, try to use high temperature dye.
5. Pre-bake the fabric once, and then printed.
Storage:
Although the heat-solid ink will not conjunctiva, storage time can be up to several years, but the proposed preservation should not be placed at high temperatures, nor should the sunshine of the place.
Store at room temperature for 12 months. And at (0 ° C to 40 ° C) under ambient conditions.
Reminder:
1, users in the use of this product, please read the instructions, and must test the suitability of different batches of ink, the actual test India, to confirm the qualified before use in bulk;
2, the above conditions in the tolerance test data for the test conditions under the test results, not as a guarantee value.
