Application and Process Analysis of Special Printing Materials

First, the water shows the pulp (water pattern)

Water display is a special printing paste for special polymer synthesis. The biggest feature of the paste is printed on the clothing. When the clothes are dry, they cannot see the pattern of the clothes. When the clothes are wet with water, they are printed previously. Flower patterns will be displayed, giving people's vision from "static" to "dynamic" special effects. The pulp water fastness can reach 3 to 4 levels, good leveling and no hand, sticky and flexible, can be widely used in acrylic, nylon, cotton fabrics, towels, swimwear, umbrellas, beach pants and other water-related The product.

Printing process: suitable for rotary screen, flat screen, elliptical machine and manual platen printing, can be printed with 100 to 200 mesh screens, printed cloth (clothing) → printing → baking (100°C~130°C/15~30) Second) → finished product.

Second, aroma glue series

The aroma paste consists of a white paste and a transparent paste. It is a micro-encapsulation technology that uses a microcapsule technology to coat the perfume and add a high-molecular substance such as EVA or PU to form a water-based aroma paste. The pressure, heat, friction, and natural diffusion are slow. Releases scent. In general, the fragrance can be maintained for more than six months. Applicable to paper, toys, clothing and other industries.

Aromatic flavors of scented mortars are: rose, jasmine, mint, lemon and so on.

Printing process: apply 800 # -1000 # mesh, printing - drying - finished products.

Reference formula: (1) Used alone: ​​scented glue 100%

(2) Addition: Aroma sizing 88%-95%

Color paste 5%-12%

Third, the latest application of temperature change process

Temperature change printing process, also known as thermal or temperature printing process. The slurry is a color or colorless at room temperature. According to the change of the outside temperature, the color of the flower position printed on the fabric instantly changes, and can change with the change of temperature. After cooling, the color of the flower is It's refreshing and amazing.

Temperature-varying paste is a further application of the cryptography technology. Through the change of the process, a piece of clothing displays different color patterns in different temperature ranges. This process printing is widely used in a variety of packaging, clothes, children's clothing, advertising posters and other effects can get unexpected "temperature change color" effect flower.

Temperature change process: bottoming → printing temperature change slurry → drying (drying) → finished product.

Temperature change process 2: India temperature change slurry → dry (drying) → finished product.

Temperature change process III: printing with water slurry or other printing paste → drying (drying) → printing temperature-transforming → drying (drying). The two printing processes are combined into one. When the temperature exceeds 32°C, the temperature-changing paste becomes colorless and the background color pattern is displayed. When the temperature is lower than 32°C, the temperature-varying pulp pattern is reflected, and the pattern is changed. The status of the pattern cannot be changed.

Fourth, the application of high-gloss water-based ink

The water-based highlighting ink consists of a white glue and a transparent two-part component, which is an acrylate and waterborne polyurethane grafting composition. The biggest feature of water-based highlighting ink is its good lightness, good elasticity, good mesh coverage, strong hiding power, smooth surface, and no stickiness after filming. It can be widely used in the printing of cotton, hemp and fabric blends. Its printing process is the same as ordinary printing paste.

Reference formula: (1) When used alone: ​​High gloss waterborne white glue 100%

(2) High-gloss water-based white glue 30 to 50% for color printing

High-gloss water-based transparent paste 50 to 70%

Can also be printed on two or three times transparent paste and then cover the white paste, so that the surface of the printed pattern is smooth, the gloss is particularly good, the effect is as if the surface cover printing plus the same paste. ,

Fifth, a new generation of environmentally friendly fire-retardant glue

This is a new type of environmentally-friendly flame-retardant glue introduced by Zhongyi Company in early 2010. It is formed by the direct polymerization reaction of polymer compounds, and then added other emulsification, dispersion and other substances to produce environment-friendly flame-retardant white glue and environmental protection flame-retardant transparent Pulp. This new type of environmentally-friendly flame-retardant paste has changed the previous drawbacks of the opaque and non-environmental protection of the fire-retardant adhesive, has good flame retardancy, does not produce flames in the event of an open flame, and does not produce black poisonous gas, and its environmental protection scalars have been achieved. European standard. The use of this kind of paste printing can make the substrate form a special protective layer on the surface of the object during the heating process, so that the object is isolated from oxygen and flame, so that the flame is extinguished, especially suitable for cotton, hemp, etc. For textile fabrics, the printing process can refer to the process of printing paste.

Sixth, Fantasy Pulp

Fantasy Pulp is a new product independently developed by Zhongyi Company in 2009 and is a non-leafing metallic special printing paste. Its advantages: After the addition of color (coating), through the 80 to 120 mesh screen printing, the substrate will produce a special light color. That is, after adding red paint through screen printing, it will emit red luster; after adding yellow paint through screen printing, it will send out "gold" luster ... fancy color. Its soft touch, good water-washing fastness, excellent elasticity, easy use, exceptionally strong sense of production, and great changes, are highly favored by consumers.

Fabric special printing can get special printing effect. Because of its unique style, beautiful and novel, it is loved by people and adds beautiful colors to people's cultural life. Fantasy printing is a kind of special printing technology which uses the simplest silk screen printing method to make the substrate different gloss and special printing effect. Fantastic paste printing is similar to ordinary fabric printing and does not require special board making and other special requirements.

Printing process: In order to achieve a smooth surface, strong hiding power, and good brightness, it is necessary to overprint two or more times of fantasy base paste. Namely: printing - drying - printing - air drying or baking (130 °C ~ 140 °C 15 seconds ~ 25 seconds) - finished products; need to increase the fastness, can be added to the appropriate amount of 815B bridging agent.

The equipment used in Fantastic Pulp printing is relatively extensive. You can use manual hot and cold platen, flat screen printing machine, etc., and can overprint with other colors. For example, when the latitude and longitude lines of the substrate are larger, you can use Fantasy Primer first. Make a base and then print the fragrant paste, which has a better shade effect.

1.4   Ring Stretch Wrapping Machine: To wrap coil products individually using stretch film, knited mesh and anti-rust packing paper as packaging material. The advantage is fast packing speed and convenient operation raising the work efficiency greatly and lowering the labor intensity for the workers. This machine completely replaces the manual wrapping. It is easy to ship and store, because of excellent packaging results, strong tension force, repelling moisture, preventing dust and protecting the surface of the products.
