What are the techniques for T-shirt printing?
First, the pigment is printed on the paper by printing method to make transfer printing paper, and then the color is transferred to the fabric through high temperature (heating and pressing on the back of the paper), which is generally used for chemical fiber fabrics, characterized by bright colors and fine layers. The flower pattern is realistic and artistic, but the process is currently only applicable to a few synthetic fibers such as polyester.
The transfer printing process is simple, the investment is small, and the production is flexible. It is currently popular in the market... But to be honest, the transfer printing and other types of printing are compared, the price is higher, but there is a certain grade.
Dyeing the ground color with a dye that is not resistant to the dyeing agent, after drying, printing with a dye dye containing a discharge agent or a dyeing agent at the same time. After the treatment, the dye of the printing place is destroyed and achromatic, forming A white pattern on the ground or a colored pattern formed by dyeing the flower dye. Also known as white or color pull. Can it make the effect that the clothes are washed? The color of the clothes seems to have been washed away a lot, and the smudged ~~ In fact, this is the printing. The principle of the printing is to pull out the color of the fabric fibers and make it into another lighter color. It is like a washing effect. It is a kind of cool print for men! !
3. Reduced printing
The process utilizes the difference in chemical resistance properties of different fibers in the interlaced or blended fabric, applying a stripping agent to partially remove one of the fibers in the fabric by a printing process, and retaining other fibers to form a translucent pattern. Also called burn-out printing or burnt-out printing.
4. Shrink print
By using a printing method, a chemical which can expand or contract the fiber is locally applied to the fabric, and by appropriate treatment, the difference between the fiber at the printing portion and the fiber at the non-printing portion is caused to be expanded or contracted, thereby obtaining a product having a regular uneven pattern on the surface. Such as pure cotton printed seersucker using caustic soda as a bulking agent. Also called concave and convex printing.
5. Flat screen printing
The printing mold is a polyester or nylon mesh (flower plate) fixed on a square frame and having a hollow pattern. The pattern on the flower plate can pass through the color paste, and the pattern without the pattern closes the mesh with a polymer film layer. When printing, the stencil presses the fabric, and the stencil is colored with a squeegee, and the squeegee is used to reciprocate the squeegee to make the color paste pass through the pattern to reach the surface of the fabric. The flat screen printing has low production efficiency, but has wide adaptability and flexible application, and is suitable for small batch and multi-variety production.
6. Round screen printing
The printing mold is a cylindrical nickel screen having a hollow pattern, which is installed in a certain order above the rubber belt of the circulating operation, and can rotate synchronously with the belt. When printing, the color paste is input into the net and stored at the bottom of the net. When the round net rotates with the guide belt, the scraper and the flower net which are pressed against the bottom of the net are relatively scraped, and the color paste reaches the surface of the fabric through the net pattern.
The rotary screen printing is a continuous processing, with high production efficiency, and has the advantages of roller and flat screen printing, but there are certain limitations in the fineness of the pattern and the richness of the printing color. ****Remember: The choice of rotary screen printing in color and color has certain limitations.
Also known as paint printing, since the pigment is a water-insoluble coloring matter, it has no affinity for fibers, and its coloring is achieved by coating of a polymer compound (adhesive) capable of film formation and adhesion to fibers. Pigment printing can be used for the processing of any fiber textile. It has superiority in the printing of blended and woven fabrics. The process is simple, the chromatogram is wide, the flower shape is clear, but the hand feel is not good, and the rubbing fastness is not high.
8. Water paste printing
The so-called water slurry is an aqueous slurry. It is not strong on the clothes and has a strong covering power. It is only suitable for printing on light-colored fabrics. The price is relatively flat, which is a lower-grade printing type.
But it also has an advantage, because it does not affect the original texture of the fabric, so it is more suitable for large-area printing patterns. Features soft touch, bright color ~ ~ But the water slurry has a big drawback is that the water color is better than the cloth Light color ~ ~ cloth color if it is deep, the water can not cover.
9. Glue printing
The appearance of the glue and its wide application in the water slurry, because of its very good coverage, can also print any light color on the dark clothes, and have a certain degree of gloss and three-dimensional, making the garment look more upscale So, it has been rapidly popularized and will be used on almost every print T. However, because it has a certain hardness, it is not suitable for large-area solid patterns. Large-area patterns are best printed with water-based paste, and then embellished with some glue, which can solve the problem of large-area glue and highlight patterns. The layering is also a way to sneak a large area of the field pattern into a rotten effect, but it is always hard to wear, so it is better to solve the problem of large-area printing by combining water and glue. . It has smooth and matte finish, soft, thin, environmentally friendly, etc. It can be stretched ~~ Generally, glue printing is more commonly used, like casual brands such as "pure" are basically using glue ~~~ Forget to remind you that the glue printing and water-printing printing can be washed by the ~~~ price. The glue is still more affordable than the water slurry.
10. Ink printing
The ink is not very different from the glue at first glance, but when the glue is printed on a smooth fabric such as a windbreaker, the color fastness is generally poor, and the nail can be scraped off with a strong scratch, but the ink can overcome this disadvantage. Therefore, when making windbreakers, it is generally printed with ink. The characteristics are bright and vivid, and the image is realistic. The market has a wave of people's heads printed some time ago~~ I don't know if you pay attention to it, then the clear and ultra-realistic printing is generally only Ink printing can print such an effect - sometimes you can also sprinkle some gold powder and silver powder on the ink, and feel the decorative effect is better ~ ~
The price of ink printing is not even clear, but the printing is generally based on the use of several colors, the color of the ink printing is more, it may be cheaper in the price ~~~
11. Thick board pulp
The thick plate pulp is based on the glue. It is like the glue is repeatedly printed with multiple layers. It can achieve a very neat three-dimensional effect. Generally speaking, the process requirements are relatively high, so the general printing factory is printed. Not good, some even have no technology, let alone printed, but it is the current printing method that is popular all over the world! Generally suitable for use in the comparison of sports and leisure models, the pattern generally uses numbers, letters, geometric patterns, lines, etc., the lines should not be too young. Some people also use a special pattern for printing flowers, which can be found in autumn and winter leather or thicker fabrics.
If the glue is neat, then the stone pulp is casual. ~ You noticed that when you walked on the muddy road, have you just walked through the footprints left? It is almost the same effect, it is like a piece of stone or a strip of stone shape or mud shape ~ ~ is a relatively new type of printing. More common in casual men's clothing
Foam, as the name suggests, is the pulp that is soaked, but also changed from the glue. The paste is printed on the cloth first, and then processed by the high temperature machine. The pattern is soaked up, the three-dimensional feeling is very good, a bit soft. Cotton, but after the clothes have been washed and washed many times, the three-dimensional effect will slowly disappear and flatten.
13. nylon pulp
Nylon pulp, it is said that nylon pulp has a good tension, may be named because it has less elasticity with nylon. Feel thin and cool.
Epoxy is a kind of variety that can be more three-dimensional than thick plates. It is generally used to make drip seals and is used in men's wear. When used in women's clothing, it will be used to shape the shape of the flower. This year, it can also be used to create a three-dimensional Mickey image~
The disadvantage of Epoxy is that it is easy to be smashed out if it has a large force.
Gel is a kind of gel-like transparent and flexible printing variety, the price is relatively expensive, you can understand, similar ribbon, the average may be 0.3-0.5 yuan a meter, but added a treaty 0.2-0.3CM gel in If the ribbon is in the center, its price may go to 0.8-1.5 yuan~~
16. Planting beads
Planting beads is a relatively high-demand process. Now only a handful of factories can do a good job. There are almost no such processes in general factories. Plant beads are also called toothbrush flowers, and the finished product is like a toothbrush with a root. In name, I heard that a flower has to be printed twenty or thirty times before it is printed. The finished product can reach a height of about 0.3CM. Its top is round bead. It can be used as other colors on it. Beads are general, so they are also called Zhuzhu.
17. Pressing and pressing
Embossing is to first make a pattern of the mold, and then hot pressed on the velvet or special glue, so that it rushes out of the shape of the pattern, the velvet and the pressure are easier to fall off the clothes, it is not so popular now.
18. Hand painted
The hand-painted effect is similar to the print, but it is more agile and free. It can be regarded as equivalent to painting on clothes. This sentence is almost clear to hand-painted.
New printing process
The new printing processes and technologies are widely used:
(1) Gold and silver powder printing
Gold and silver powder printing is a paint printing using a metal powder similar to gold and silver. As far as the effect of the fabric is concerned, it should have a sense of gorgeousness, that is, the printed fabric must have the effect of “inlaid gold inlaid silver”, and at the same time, the various fastnesses must meet the national standards to improve the performance.
Gold and silver powder printing is a combination of copper-zinc alloy or aluminum powder and paint printing adhesive and other additives to form a gold-silver powder printing paste printed on the fabric, so that the fabric presents a dazzling print pattern.
(2) Foam printing
Foaming printing refers to the addition of a foaming substance and a thermoplastic resin to the printing paste. In the high-temperature baking, a three-dimensional pattern having a decal and flocking effect is formed due to the expansion of the foaming agent, and the coating is fixed on the fabric by the resin. Printing process. Foam printing is a newly developed printing process, which gives the fabric a high-end gorgeous unique style, breaking through the pattern of flat printing, giving people a sense of novelty and elegance.
(3) Scent printing
The scent printing refers to a printing process in which a perfume resin is applied in a printing paste, which is smeared or sprayed and impregnated under a certain pressure to fix the perfume resin on the fabric. After the fabric is processed by the fragrance, the comfort during use is improved.
(4) Luminous printing
Substances present in a variety of colors are the result of light being reflected onto the surface of the material, producing reflection and absorption of light. That is to say, the material must present different colors in the presence of light, and there is no color without light; in the dark environment, the various colors of the material disappear. When the photo-induced solid matter is excited by sunlight or artificial light, it can emit light in the dark and can display different colors. This substance must be excited by light to illuminate in the dark, so it is called a photoluminescent substance. When the external light source is removed, the photoluminescence material has a certain limitation of the illumination time, and the duration of the illumination is called afterglow.
Luminous printing utilizes a photoluminescent substance that allows the pattern printed on the fabric to be illuminated to reveal a crystal clear and colorful pattern in the dark. If different illuminating wavelengths and different afterglow photoluminescent materials are used, dynamic effects can be achieved, and the image is vivid, and is suitable for various interior decorative fabrics.
(5) Diamond printing
The diamond print selects a low-cost object that can form a diamond-like diamond as a micro-reflector print, so that the pattern printed on the fabric has a diamond-printing process. Diamond printing is very popular among consumers because of its elegant appearance and elegant appearance. Moreover, the process is simple, the cost is low, and the fastness is excellent, and it is suitable for all printing equipment.
(6) Pearlescent printing
Pearlescent printing is printed on fabrics using a "pearl-glossy formulation" that glitters pearl-like luster due to the multi-level reflection of light. The pearl luster preparation has two kinds of Liu and artificial preparations.
(7) Color printing
Fabrics are generally printed with paint or dye, and the color is always at rest, and does not change due to changes in external conditions. The color-changing print has a dynamic effect, and the color of the printed fabric can change color depending on environmental conditions. 
Edit this paragraph heat transfer printing
The thermal transfer printing process began in the 20th century with the beginning of the 60th generation. Its predecessor was the use of chemical fiber cloth as a test carrier for thermal transfer printing. With the further development of science and technology, thermal transfer printing technology has gradually penetrated into more fields, from the initial fabric printing, to metal, plastic and other materials, from planar objects to irregular irregular objects.
Later, the thermal transfer printing technology has been further refined. For example, clothing heat transfer printing is extended, such as: hot-melt heat transfer printing, sublimation heat transfer printing, digital heat transfer printing, and the like.
First make a simple comparison:
If a customer gives you a piece of pure white polyester or a light-colored polyester-cotton fabric with a high polyester content, whether you use a silk screen printing method or a disperse dye, inkjet direct printing, or reactive printing technology, it will always be More or less brings some disappointment, either the color fastness is not good, or the hand feels hard, or the printing cost is high.
In other words, this piece of cloth can be printed with sublimation heat transfer printing to solve the above problems.
The principle of thermal transfer printing: firstly print the pre-processed printing pattern onto a specific transfer paper with thermal transfer ink, and then transfer the pattern from the transfer paper to the fabric by high temperature and high pressure. It is based on the sublimation characteristics of some disperse dyes. It can be selected to produce vaporized disperse dyes at 150-230 ° C, mixed with alcohol and other solvents to make "color ink", and then according to different design patterns, "Color ink" is printed and printed on transfer paper. Then, the transfer paper printed with the pattern is in close contact with the fabric, and under the control of a certain temperature, pressure and time, the dye is transferred from the printing paper to the chemical fiber fabric such as clothing, and penetrates into the fiber through the diffusion principle of the dye. In order to achieve the purpose of printing coloring, the entire printing process is finally completed.
The printing technology integrates green, environmental protection, low carbon, energy saving, emission reduction and ecology, and is a major breakthrough in textile printing technology. Post-press fabric, soft to the touch, bright color, rich in layers and good breathability.
Throughout the entire thermal transfer printing process, complicated processes such as post-washing, fixing, and steaming, such as reactive dye printing, are not required, and post-press setting is not required, thereby saving a large amount of production time and shortening the delivery time.
The thermal transfer printing process can pre-inspect the printed paper before the printing of the fabric, and can be removed at any time if it is found to be inaccurate and dragged. Therefore, clothing such as clothing printed by the thermal transfer printing process rarely exhibits defective prints.
