Today, as people's increasing demands for products, the emergence of many new non-woven bag, non-woven bags and non-woven shopping bags printing, where tradition to introduce non-woven bag factory several.
Common printing methods are: the first is screen printing, but also the most commonly used, screen printing belong to stencil printing it with flat printing, letterpress, gravure printing method is called together the four. Stencil printing including transcribed version, holes flower version, fountains and screen printing. Principle stencil printing are: the plate (to produce a paper film version or the other version of the version of the base by the ink aperture) at the time of printing, by a certain pressure to transfer the ink to the substrate (paper, ceramics through the stencil perforations, etc. ) to form an image or text. In this remind you that one, woven bags need to be cleaned regularly, because printing ink above a certain bacteria, so regular cleaning it, in order to better environmental protection. The second is the watermark, because of the use of water-based mortar shells named as print media, more common in textile printing, also known as printing. When printing the paste and water-based elastomeric rubber reconcile. Without chemical solvents, can be washed with water directly photofinishing edition. It features good color strength, with strong cover and fastness, washable, virtually no odor. The third is gravure printing, processing of finished products using this method is usually called laminating non-woven bags. This two-step process, that is, first using the traditional gravure process will be printed onto film graphic, then using coating process will be printed on a thin film composite nonwoven fabric pattern. Usually large color patterns printed woven bags are made of this process. It features beautifully printed, full use of machine production, short production cycle. Another product has excellent water resistance, durability of the finished product than other non-woven bag production process better. There are two kinds of light and matt films to choose from, with frosted matte effect! The disadvantage is that there is a conflict with the concept of environmental protection, because the film is difficult to degrade. The fourth is thermal, thermal transfer printing belong in specialty printing! This method requires the intermediate medium, that is, first by printing or thermal transfer paper to the thermal transfer film, and then heating the pattern is transferred to the nonwoven fabric by the transfer device. Commonly used in textile printing medium is a thermal transfer film. Its advantages are: the fine print, there are rich level version, comparable photos. Small area of color applied to the image printing. The disadvantage is the high price, high printing costs. These are today saying.
