(English: tropical print) Pigment is printed on paper to make transfer paper, and then the color is transferred to the fabric by high temperature (heating and pressurizing the back of the paper). Generally used in chemical fiber fabrics, it is characterized by bright colors, delicate layers, realistic patterns and strong artistry, but this process is only suitable for a few synthetic fibers such as polyester.

Transfer printing technology is simple, investment is small and production is flexible. At present, it is quite popular in the market ... but to be honest, compared with other printing types, this transfer printing is a bit expensive, but it has a certain grade.

Discharge printing

Discharge printing (discharge printing) background color is dyed with dyes that are not resistant to discharge agents. After drying, the ground color dye is printed with slurry containing discharge agent or both. After post-treatment, the background dye at the printing place is destroyed and discolored, forming a white pattern on the ground or a color pattern dyed with a design dye. Also known as line drawing or color painting. It can make clothes look like they have been washed with water. The color of the clothes seems to have been washed a lot, mottled ~ ~ in fact, this is a print. The principle of printing is to draw out the color of the fabric to make it lighter, which is stronger than washing. It's a cool print for men's wear! !

Reduce printing

This process takes advantage of the difference of chemical corrosion resistance of different fibers in interwoven or blended fabrics, and uses burnout agent to partially remove one fiber in the fabric through printing, leaving other fibers to form translucent patterns. Also known as burnt-out printing or burnt-out printing.

Shrink printing

By means of printing, chemical substances that can make the fibers expand or contract are applied locally, and through proper treatment, the fibers in the printed part and the fibers in the non-printed part have differences in expansion or contraction, so as to obtain products with regular concave-convex patterns on the surface. For example, pure cotton printed seersucker is used as bulking agent. Also known as relief printing.

Plane screen printing

The printing die is a polyester or nylon wire mesh (pattern) fixed on a square frame and has a hollow pattern. The color paste can penetrate the pattern on the pattern board, and the mesh is sealed with polymer film where there is no pattern. When printing, press the pattern plate on the fabric, fill the color paste on the pattern plate, and scrape it back and forth with a scraper to make the color paste reach the surface of the fabric through the pattern. Flat screen printing has low production efficiency, but wide adaptability and flexible application, which is suitable for small batch and multi-variety production.

Rotary screen printing

The printing die is a cylindrical nickel mesh with hollow patterns, which is installed above the circulating rubber belt in a certain order and can rotate synchronously with the belt. When printing, the color paste is input into the screen and stored at the bottom of the screen. When the rotary screen rotates with the guide belt, the scraper closely attached to the screen scrapes against the flower screen, and the color paste reaches the fabric surface through the patterns on the screen.

Rotary screen printing is a continuous process with high production efficiency, which has the advantages of roller and flat screen printing, but it still has some limitations in pattern fineness and printing color richness. * * * * Remember: Rotary screen printing has certain limitations in color selection.

pigment printing

Pigment printing is also called pigment printing. Because pigment is a water-insoluble coloring substance, it has no affinity for fibers, and its coloring depends on the coating of polymer compounds (adhesives) that can form films and the adhesion to fibers. Pigment printing can be used in the processing of any fiber textiles, and it has more advantages in the printing of blended fabrics and interwoven fabrics. The process is simple, the color spectrum is wide, the flower outline is clear, but the handle is poor and the rubbing fastness is low.

watermark

The so-called water slurry is a water-based slurry. Printed on clothes, the feeling is not strong and the coverage is not strong. Only suitable for printing on light-colored fabrics, and the price is relatively flat. It belongs to a relatively low-grade printing type.

However, it also has an advantage, because it will not affect the original texture of the fabric, so it is more suitable for large-scale printing patterns. It is characterized by soft feel and bright color ~ ~ but water slurry has a great disadvantage. The color of the slurry is lighter than that of the cloth ~ ~ If the cloth is deeper, the slurry can't cover it at all.

Viscose printing

After the mucilage in water slurry appears and is widely used, because of its excellent coverage, dark clothes can also be printed in any light color, and it has a certain luster and three-dimensional sense, which makes clothes look more upscale, so it is rapidly popularized and used almost every time when printing T, but it is not suitable for large-scale field patterns because of its certain hardness. It's best to print a large area pattern with water slurry first, and then decorate it with some mucilage, which can not only solve the problem of large area mucilage hardness, but also highlight the layering of the pattern. Another way is to cut corners in a large area and let it rot, but it is a little hard to wear all the time. It is better to combine water with mucilage to solve the problem of large-scale printing. With a smooth matte surface, it is soft, thin and environmentally friendly, and can also be stretched ~ ~ Generally speaking, mucilage printing is commonly used. Leisure brands such as "Pure" are basically made of mucilage ~ ~ I forgot to remind you that both mucilage printing and water slurry printing can be washed ~ ~ ~ Comparing the two prices, mucilage is still more affordable than water slurry.

Ink printing

At first glance, ink is not much different from mucilage, but when mucilage is printed on smooth fabrics such as windbreaker materials, the color fastness is generally poor, and it can be scraped off with nails, but ink can overcome this shortcoming. Therefore, when making windbreakers, ink is usually used for printing. Its characteristics are vivid and vivid. Some time ago, there was a wave of head printing in the market ~ ~ I don't know if you have noticed it. Generally speaking, only ink printing can print that effect ~ Sometimes you can sprinkle some gold powder and silver powder on the ink, which makes the decoration effect better ~ ~

I don't know the specific price of ink printing, but the general price of printing depends on how many colors are used. Ink printing has many colors, and the price may be a little cheaper ~ ~ ~

Thick plate slurry

Thick paste is based on mucilage, just like mucilage repeatedly printing many layers. Can achieve a very neat three-dimensional effect. Generally speaking, the process requirements are relatively high, so ordinary small printing plants can't print well, and some don't even have this technology, let alone print well, but it is a printing method that is popular all over the world at present! Generally suitable for sports and leisure. Numbers, letters, geometric patterns, lines, etc. Generally used in patterns, lines should not be too young. Some people have a unique style to print patterns, which can be found in autumn and winter clothing leather or thicker fabrics.

If the mucilage is neat, then the mucilage is random ~ ~ Have you noticed the footprints you just left on the muddy road? Almost the same effect. Like a stone or a piece of mud. This is a relatively new printing variety. More common in casual men's wear

Bubble pulp

Soaking pulp, as the name implies, is soaked pulp, which is also changed from mucilage. First, the prepared slurry is printed on the cloth, and then the pattern is soaked in a high-temperature machine. The three-dimensional effect is good and a little soft, but the three-dimensional effect will gradually disappear and flatten after the clothes are washed many times.

Nylon pulp

Nylon pulp is said to have good tension, which may be named because its elasticity is smaller than nylon. It feels thin and cold.

Drip glue

Drip glue is a kind of variety that can have a more three-dimensional effect than thick plate. It is generally used for sealing glue drops, mostly for men's wear. If it is used in women's clothes, it will be used to make flowers. This year can also be used to create a three-dimensional Mickey image ~

The disadvantage of glue dripping is that it is easy to fall off with a little force.

gel

Gel is a kind of transparent and elastic printing variety like gel, and its price is relatively expensive. You can know that a similar ribbon may be 0.3- 1 m in 0.5 yuan, but if a gel of about 0.2-0.3CM is added in the center of the ribbon, its price may reach 0.8- 1.5 yuan ~.

Plant bead

Planting beads is a demanding process. Now only a few factories can do it well, and almost no factory has this technology. Planting beads is also called toothbrush flower, and the finished product is named after the erected toothbrush beard. It is said that a flower needs to be printed twenty or thirty times before it can be printed well. The height of the finished product can reach about 0.3CM. Its top is round, and other colors can be made on it, which looks like beads, so it is also called.

Velvet pressing and glue pressing

Embossing is to make a pattern mold first, and then press it on the flannel or special glue to make it out of the pattern shape. Velvet pressing and glue pressing are easy to lose clothes, so they are not so popular now.

hand paint

Hand-painted effect is similar to printing, but it is more flexible and free, which can be regarded as equivalent to painting on clothes. This sentence is almost clear, hand-painted.

New printing technology

The widely used new printing technologies and processes mainly include:

(1) gold and silver powder printing

Gold and silver powder printing is a pigment printing with metal powder similar to gold and silver color as colorant. As far as the fabric effect is concerned, it should be gorgeous, that is, the printed fabric should really have the effect of "gold inlaid with silver", and at the same time, the color fastness should meet the national standard to improve the performance.

Gold and silver powder printing is to mix copper-zinc alloy or aluminum powder with additives such as pigment printing adhesive to make gold and silver powder printing paste, which is printed on the fabric to make the fabric show dazzling printing patterns.

(2) Foam printing

Foam printing is a printing process in which foaming substances and thermoplastic resin are added to printing paste, and three-dimensional patterns with decal and flocking effects are formed due to the expansion of foaming agent during high temperature baking, and the paint is fixed on the fabric through resin. Foam printing is a newly developed printing process, which endows fabrics with high-grade and gorgeous unique style, breaks through the pattern of plane printing and gives people a novel and elegant feeling.

(3) fragrance printing

Fragrant printing refers to the printing process in which perfume resin is coated on the printing paste, scraped or sprayed or impregnated under a certain pressure, so that the perfume resin is fixed on the fabric. After perfume treatment, the comfort of the fabric is improved.

(4) luminous printing

The appearance of different colors of matter is the result of reflection and absorption when light strikes the surface of matter. In other words, matter can appear in different colors only when there is light, and there is no color without light; In a dark environment, all colors of matter will disappear. Light-sensitive solid substances can glow in the dark and present different colors under the excitation of sunlight or artificial light. This substance must be excited by light to emit light in the dark, so it is called photoluminescence substance. When the external light source is removed, the luminous time of the photoluminescent substance is limited to a certain extent, and the luminous duration is called afterglow.

Luminous printing is to use photoluminescent substances to make the patterns printed on fabrics appear crystal-clear and beautiful in the dark after illumination. If photoluminescent substances with different luminous wavelengths and afterglow are used, the dynamic effect can be achieved, and the image is vivid, which is suitable for various indoor decorative fabrics.

(5) Diamond printing

Diamond printing is a printing process that selects low-cost objects with similar diamond light as micro-reflectors, so that the patterns printed on fabrics have diamond light. Diamond printing is favored by consumers because of its beauty and generosity. But also has simple process, low cost and good fastness, and is suitable for all printing equipment.

(6) Pearlescent printing

Pearlescent printing is a kind of "pearl luster preparation" for printing on fabrics. Due to the multi-layer reflection of light, this preparation can shine like pearls. There are two kinds of pearl luster preparations: natural preparations and artificial preparations.

(7) Color change printing

Generally, fabrics are printed with pigments or dyes, and their colors are always in a static state and will not change due to changes in external conditions. Color-changing printing has a dynamic effect, and the color of printed fabric can change color with the change of environmental conditions. [ 1]

Edit this thermal transfer

The thermal transfer process began in the early 1960s, and its predecessor was chemical fiber cloth as the experimental carrier of thermal transfer. With the further development of science and technology, thermal transfer technology has gradually penetrated into more fields, from the initial cloth printing to materials such as metal and plastic, from flat objects to uneven and irregular objects.

Later, thermal transfer technology developed more finely. Take clothing thermal transfer as an example, such as hot melt thermal transfer, sublimation thermal transfer and digital thermal transfer.

First, make a simple comparison:

If a customer gives you a piece of pure white polyester or light-colored polyester-cotton fabric with high polyester content, whether you use paint or disperse dyes for screen printing, direct ink-jet printing or reactive printing technology for printing, it will always bring some disappointment, either with poor color fastness, hard handle or high printing cost.

In other words, this kind of cloth can be printed by sublimation thermal transfer, which can solve the above problems well.

Principle of thermal transfer: First, the pretreated printed pattern is printed on a specific transfer paper with thermal transfer ink, and then the pattern is transferred from transfer paper to the clothing fabric through high temperature and high pressure. According to the sublimation characteristics of some disperse dyes, disperse dyes which can vaporize at 150 ~ 230℃ are selected and mixed with solvents such as alcohol to make "color ink". Then, according to different design pattern requirements, the "colored ink" is made into printed patterns and printed on the transfer paper. Then, the patterned transfer paper is in close contact with the fabric. Under the condition of controlling certain temperature, pressure and time, the dye is transferred from printing paper to chemical fiber fabrics such as clothing, and penetrates into the fiber through the diffusion principle of dye, so as to achieve the purpose of printing and coloring, and finally complete the whole printing process.

This printing technology integrates green, environmental protection, low carbon, energy saving, emission reduction and ecology, which is a major breakthrough in textile printing technology. The printed fabric has soft hand feel, bright color, rich layers and good air permeability.

In the whole thermal transfer process, there is no need for complex processes such as post-washing, color fixing and steaming like reactive dye printing, and there is no need for post-press setting, which saves a lot of production time and shortens delivery time.

Thermal transfer process can check the printed paper in advance before cloth printing, and once defects such as dislocation and color dragging are found, they can be removed at any time. Therefore, fabrics printed by thermal transfer technology, such as clothing, rarely appear defective printing.
