Green symbolizes life, health and vitality. Green environmental protection has become the main theme of today's society. The most important link in the field of textile and clothing is green printing. With the government increasingly strict environmental punishment measures and trade environmental protection barriers, green printing is worthy of a wise choice of enterprises. Non-“green†cannot survive. It has become a not-too-distant future. Only the strong advocates of green printing will not be abandoned by this irreversible trend. Green ink is the need for green printing, and water-based ink has been developing in recent years. There are more and more types of manufacturers and products at home and abroad. Of course, the defects of water-based ink are inevitable. Then, we believe that with the continuous development of environmentally friendly ink products and technologies, it will play an increasingly important role in the future of green printing. The more important roles and status.
Green ink
Apparel screen printers have begun to use water-based inks in order to meet customers' requirements for environmentally friendly materials. It is generally believed that if inks are soluble in water and no mineral spirits or harmful chemicals are used in the washing process, then they will not The environment has an impact. Some people may think that there are many restrictions on the use of water-based ink, such as the use of a lower screen number, and the ability to print on dark T-shirts. As soon as this statement came out, it immediately caused panic among printing companies.
Some features of water-based ink
Traditional water-based inks contain 60% to 70% of water, causing them to mistake that the remaining 30% to 40% of the solids in the ink is not enough to be responsible for local government regulations related to waste disposal and compliance production. . However, in fact, the treatment of water-based ink specifications is very similar in many respects to thermosetting inks. All manufactured inks must be provided with a MSDS for downstream printers. In addition, because the water-based ink also emits volatile organic compounds, necessary ventilation must be maintained.
Water based ink
Since the late 1950s, water-based inks have been applied to the field of apparel printing. Although plastisol inks have opened up a new era of large-scale printing T-shirts, and in recent years, especially with the continuous advancement of technology, its market share has increased, but water-based inks still have a place. And it remains as a core production tool for many printing companies.
Manufacturers are more willing to choose water-based ink, one of the reasons is that this ink is cheaper than thermoset ink, is a production element that can save a lot of costs, especially suitable for long-lived printing of light-colored clothing. Moreover, this kind of ink is also very convenient for the manufacturer's own production. Printing companies can purchase raw materials separately and then mix them in a production workshop. Self-production is a good way to save money because the life cycle of mixed inks is shorter than that of thermosetting inks. Its feel is very soft, and it is easy to dilute with water. Although it can only be used on white clothes, people do not care about the problem of color stability and transparency.
