Textile inkjet technology

Some experts predict that ink-jet printing technology will open up a new window for textile printing, and it will make great achievements in the new century that highlights personalization. At present, inkjet printing technology has been applied to clothing, home textiles, wallpapers, carpets, woven ribbons, labels, flags, ties and scarves. Designers, entrepreneurs, merchants and consumers all over the world have found that textile textile printing technology can obtain personalized textiles with low cost and high quality.

According to statistics, the printing products in the world's textile production account for 11% to 13%, while about 58% of printed textiles on the market are produced by rotary screen printing machines, flat screen printing machines account for 28% of production, and the remaining 3% are Intaglio printing, 5% transfer printing, and 6% hand-made. With traditional textile printing methods, the time usually used for engraving is often more than half of the production time. Because the fabrics are updated more and more quickly, the method of reducing the cost is to eliminate the screens and their preparation, and to combine the printing and the sample preparation. Therefore, the textile ink jet printing technology has emerged as the times require.

Inkjet printing has become an advanced technology that satisfies textile printing. Compared to traditional textile printing methods, it has the following advantages: unlimited number of colors; unlimited copy length; no need to make screens, saving a lot of time; pattern design and changes can be performed on a computer screen, and color matching can be performed. The use of the mouse to carry out; did not make the screen costs; reduce the time and save the printing materials; reduce labor costs.

The biggest factor affecting textile printing is the length of the fabric. When the length of the fabric is very long, it can be printed quickly, continuously and economically in the traditional printing method. If the speed of rotary screen printing is very high, about 30 to 70 meters per minute, the range of color choices can be very wide, and no special pretreatment is required before printing. However, traditional printing methods are not economical for small batch production. Taking the traditional printing process such as rotary screen printing as an example, usually with 100 dpi (no more than 255 dPi) digital design information, through the laser engraving pattern, but also to determine the repeat distance, the screen manufacturing cost is very large (including engraving, washing, storage, etc. ), Usually the design is not allowed to spend on the assembly, different batches have to play different samples, time-consuming and laborious. When producing in small batches, because of long downtime, waste of fabrics and ink is much, engraving costs are also high, and time spent on color matching, pulping, design, trial production, and labor are high. The operation such as the engraving of the screen, the washing of the printing and the washing of the screen will bring about certain pollution. Designing samples and checking work is often very long and it takes a lot of work. Inkjet printing has great advantages. For small batches, proofing or school research, it does not require a screen, so the expenses incurred as a result, such as engraving screens, slurry preparation, printing, parking, etc., have disappeared. Inkjet printing has no problem of image registration, and its repeated size can be unlimitedly selected, and the consumption of dye, water, and energy is relatively small, which is especially suitable for timely delivery and different needs of many customers.

Inkjet printing technology is still limited by low-speed production; only low-viscosity dyes can be used, and the printing size is small; and the fabric must be specially treated so that it can quickly absorb the dye; in the selection of dyes, many special printing Colors such as pearls, metals, and white cannot be used for spray heads.

At present, the developed textile industry in the world has increased its interest in inkjet printing applications. Inkjet printing is fast, flexible, clear-cut, creative, competitive, and eco-friendly. It conforms to small-batch, multi-variety production models. Some large companies believe that inkjet printing technology is very beneficial in exploiting international business: In order to maintain competitiveness, companies must cooperate internationally. Inkjet printing technology enables rapid conversion of original design copies, allowing ideas and samples to be exchanged in a timely manner. A textile that meets the customer's needs and is unusual, so that production can be brought close to the market and can quickly benefit.
