Screen printing is a kind of printing with a wide range of applications. According to the different printing materials, it can be divided into: fabric printing, plastic printing, metal printing, ceramic printing, glass printing, electronic product printing, lottery silk screen printing, advertising decoration silk screen printing, Metal advertising board screen printing, stainless steel products screen printing, light reflector screen printing, silk screen transfer aluminum, screen printing and lacquer screen printing and so on.
1. Direct Printing of Paints Direct printing is the process of printing directly onto a fabric by printing a prepared paste. This is the simplest and most commonly used process in the printing process. Paint direct printing process generally refers to white or light-colored fabric printing, it is easy to spell color, the process is simple, after printing can be processed by bake, apply a variety of fiber textiles. The paint direct printing process can be classified into Accraming F-type adhesives based on the currently used adhesives. Acrylic adhesive, styrene-butadiene emulsion and chitin adhesive are three direct printing processes.
2. The main methods of silk printing silk printing are direct printing, discharge printing, and anti-inking printing. The direct printing method has already been introduced. The method of discharge printing, transfer printing, and osmotic printing will be introduced separately in the following subsections. Here, the anti-inking printing method is mainly introduced.
3. Knitted Underwear Printed Knitted Underwear Printing The main application of direct coating printing process, fabric printing after the double drying or natural drying, to avoid the knitted fabric wet processing easy deformation and wet processing problems difficult. The printing method is mainly based on flat screen printing, and is divided into manual scraping and machine operation. This printing method can adapt to pattern patterns of various composition forms and organizational structures, and is suitable for production needs of small batches and multiple colors.
4. Discharge printing Dispensing printing, also known as stencil printing, refers to the use of discharge agents printed on colored fabrics to destroy some pigments that have been dyed, and thus obtain a variety of patterns and patterns of printing. Dispensing agents are chemicals that decolorize the dyed bottom. Such as: hanging white, stannous chloride and so on. This method can be divided into white (pull white) and pattern is colored (pull) two. The latter dyeing method makes the fabric pattern fine, but the process is complicated and the cost is high.
5. The silk screen burn-in and burn-out system utilizes two kinds of fiber blended fabrics with different acid resistance. After the acid burn-in paste printing and chemical processing, the acid-resistant natural fibers are partially rotted to expose the acid-resistant chemical fiber part, forming a crystal clear The transparent pattern, its special style makes the burnt-out products have a high-grade and beautiful feeling. Burnt-out products are not only beautiful in appearance, but also have excellent internal quality. They are wear-resistant, high-strength, good-cleaning, quick-drying, and non-ironing. They are welcomed by domestic and foreign markets. The research and application of burnt-out technology has prevailed in the textile printing and dyeing industry in recent years.
6. Wool Fabric Printing At present, printed wool fabrics are mainly made of thin plain fabrics or voile fabrics. Most of them are used to make women's shirts, dresses, quilts and skirts. In addition to direct printing, wool fabric printing also includes printing, anti-printing and transfer printing. Wool blend fabric printing also occupies a certain percentage. At present, the embossing of wool fabrics is also popular and is mainly used for woolen sweaters.
7. The velveteen printed diamond printing uses the characteristics of the silk screen printing on the velveteen to obtain a special flash effect, which can emit the natural light in the sunlight.
8. Foam printing fabrics There are many kinds of special printing, foam printing is one of them. Foam printing is characterized by: strong three-dimensional impression, similar to artificial embroidery, soft to the touch, wear-resistant, washable, fastness, good elasticity, and can be widely used in tablecloths, curtains, tea towels, handkerchiefs, pillow covers, clothing, travel Souvenirs and other aspects. It can not only be applied to natural fiber fabrics such as cotton, hemp and silk, but also can be applied to artificial fiber fabrics.
9. Flocking printing electrostatic flocking is a new technology that is currently emerging in the textile industry. It is a product that uses high voltage electrostatic fields to plant short fibers on top of a grey cloth. Flocking products have a simple process, strong three-dimensional effect and low cost, so they are widely used in rubber, plastics, artificial leather, and decorative products, especially for small-batch tourism products. The use of flocking patterns on shoes and hats, children's wear, logos, and apparel will make it look unique.
10. Transfer printing Transfer printing is a printing process that relies on the sublimation of dyes and the effect of dye vapors on the diffusion and affinity of fibers to complete the coloring effect. Transfer printing is a kind of printing and dyeing production method that is more practical in water-free processing. In addition to not using water, one of the main features is the small paper deformation, so you can print fine multi-level patterns and photographic images. Really transfer the picture of the pattern to the cloth. The effect is sometimes better than general anti-discharge printing.
In addition to the above ten kinds of common printing methods, there are some special printing methods, such as: transfer of aluminum foil printing, photoluminescent printing, fluorescent printing, gold, silver powder printing, paint foam printing, color printing, fragrance printing, diamond printing and Pearl printing, etc., printing methods.
