Top 10 frequent printing techniques, an everyday dress, to be different.Printing technique is the key.Originally regular fabrics, via a variety of printing technology, style, fashion has a totally special feeling.It's absolutely amazing!Let's take a seem at 10 frequent printing techniques.
1. Roller printing
The manner of printing on the material by using capability of copper cylinder with concave sample (cylinder for short), stained with shade paste, is referred to as drum printing.When the curler printing imprint on the fabric, the shade paste is transferred to the material and printed pattern.
2. Digital printing
Digital printing, printing the use of digital technology.Through digital face reading, images, or laptop scanning, processing a range of digital diagram enter into the calculation, once more after processing by way of pc shade printing system, a committed RIP software program thru the spray printing gadget between a number of types of printing distinct dye choice (reactive, disperse, zhu coating) spray print without delay to all sorts of cloth or different medium, after processing, on the a number sorts of fabric cloth to attain the required printing merchandise of a number of sorts of excessive precision.Digital printing process can be subdivided into the following categories

I. classification by printing method

Digital printing is a general term for ink-jet printing technology. In order to clearly explain various printing methods and characteristics, this paper introduces the digital printing of textile fabrics in an all-round way, various types and process decomposition.

1. Digital direct jet printing

Digital jet printing method for dispersive, acid dyes, coating, reactive ink, digital jet printing is directly on the plasma sprayed directly on the bulk fabric printing process, the technological process is: according to the textile, choose the corresponding ink to carry on the design pattern, sizing, and then to the textile direct injection directly spray printing printing machine, and then drying, steaming, washing, drying, and soft to finalize the design process (including paint just baking can be solid color)

2. Heat transfer printing

Thermal transfer printing is the printing of textile dye on paper (coated), and then use thermal transfer printing machinery to transfer the pattern on paper to textiles.Advantage is higher precision, but printing efficiency is low, can only do polyester or polyester containing high textiles, which transfer fabric is processed through semi-finished products and without added softener (added softener may affect the color rate).

3. Cold transfer

As with thermal transfer printing, textile dye needs to be printed on the paper, and then with special machinery paper and fabric embossing, to achieve the transfer of patterns.

There are two ways to treat the fabric after embossing:

One is the traditional steaming, washing, shaping and other traditional processing;

The other is to conduct cold reactor chemical reaction to treat solid color (the fabric needs chemical treatment in advance).This process applies to all fabrics other than blends using reactive, disperse, acidic dye inks.

Classification by dye and process

1. Scatter digital printing

At present, more than 50% of the ink used for printing in China is disperse dye ink, which is used for polyester fiber printing.Disperse dyes are a kind of non - ionic dyes with low water solubility and high dispersion in water by means of dispersing agent.

2. Reactive digital printing

Reactive ink about 29%, mainly used for printing silk and cotton fabrics;Reactive dyes, also known as reactive dyes.A class of dyes that chemically react with fibers during dyeing.This kind of dye separations contain the gene that can produce chemical reaction with the fiber. When dyeing, the dye reacts with the fiber, forming a covalent bond between the two to form a whole, which improves the fastness to washing and rubbing.The active fuel molecule consists of two main components, the parent dye and the active group. The group that can react with the fiber is called the active group.At present, it is mainly used in cotton, general linen, silk and other woven and knitted fabrics or fabrics with higher components.

3. Acid digital printing

Acid dye ink small proportion, about 7%, used for wool, nylon and other fabrics printing.Acid dyes are a kind of water-soluble dyes with acid groups in their structure, which are dyed in acid medium.Most acid dyes contain sodium sulfonate salt, soluble in water, bright color, complete chromatography.Mainly used for wool, silk and nylon dyeing, but also for leather, paper, ink and other aspects.Cellulose fibers generally have no coloring power.

4. Pigment ink for digital printing

China's use of pigment ink is relatively small, less than 2%, mostly foreign products, manufacturers have huntsman, basf, dupont, klein and other companies.

Three, according to fabric composition classification

1.Cotton - based digital printing, but hemp, silk can also be used reactive ink;

2.Mainly chemical fiber digital printing, with the production of disperse thermal sublimation dye ink and chemical fiber disperse direct spray digital;

3.For some mixed fabrics such as T/C, which cannot be operated with reactive, disperse and acid dye ink, use paint ink to print;

4.Nylon and wool based digital printing, with acid dye ink production, silk can also be.

3. Round screen printing

With a hollow pattern of cylindrical nickel screen, installed in a certain order in the top of the rubber guide belt circulation, color paste input in the net, resident in the bottom of the net, the round net with the guide belt rotation, the squeegee at the bottom of the net and flower net relatively scraping, color paste through the net pattern to the surface of the fabric.

4. Flat screen printing

Printing mold is fixed on the square frame with hollow pattern polyester or nylon screen (flower version).Flower plate on the pattern can be through the color paste, no pattern is closed with polymer film mesh.Printing, flower plate pressing fabric, flower plate on the color paste, with a scraper reciprocating scraping pressure, color paste through the pattern to the surface of the fabric.Flat screen printing production efficiency is low, but wide adaptability, flexible application, suitable for small batch production.

5. Water paste printing

Water-based printing paste, soluble in water, the sauce itself is relatively thin.When printing, the printing paste through the screen screen screen screen holes evenly to the required parts of the printing, so that the pattern can be printed on the T-shirt.

6. Glue printing

The basic process is the same as water paste printing, but the material used is the glue paste pigment that will solidify on the fabric after drying, a little like a ointment against the skin.At present, the most common printed t-shirts in the market are printed with glue.

7. Flocking printing

Flocking is a kind of high demand technology, now only a few factories can do it well, the general factory almost do not have this kind of technology. Flocking is also called toothbrush flower, the effect of the finished product is like a stick of bristles, so named, the height of the finished product can reach about 0.3CM, can be made in other colors, so also called flocking.

8. Pigment printing

(English: pigment print) and pigment printing, because the paint is water soluble colouring matter, no affinity of the fibers, the color must rely on film-forming polymer (adhesive) coating and the adhesion effect of the fiber is implemented.Pigment printing can be used in the processing of any fiber textile, in the printing of blended and interwoven materials, and the process is simple, the color spectrum is wider, the shape of the flower is clear, but the hand is not good, the rubbing fastness is not high.

9. Dye and print

(English article: wash out colors) (discharge) discharge print (discharge printing) choose not resistant to discharge paste with dye color, after drying, use detergent containing discharge agent or with resistance to discharge at the same time the design and color of the dye printing paste printing, post-processing, printed in ground are destroyed and the decolorization of dye, the color of the earth formed white or color pattern formed by the dye uptake of design and color.Also known as white or color pull.Can it make it look like the clothes have been washed?

The color of clothes seems to be washed off a lot, mottled ~~ actually this is pull print, pull print principle is to pull out the color of fabric tissue fiber, make it become another kind of lighter color, strong like washing water effect, is a kind of men's wear more cool printing oh!
