Physical and physicochemical methods to enhance the dyeing dyeing wastewater can reduce chemical pollution, but to pay attention to labor protection in the processing of textiles. Custom Car Flags These staining methods is still in the research and development stage.

The is printed to form patterns on the fabric a certain way to dye or paint. Fabric , also known as the local dyeing of fabrics. The properties of the chemical additives used in dyeing and using the same dye similar dye coloring mechanism is the same fabric dye in the process of taking the fastness requirements are the same. However, the dyeing and , there are many different places, mainly in:
① processing medium. The dyeing process is based on water as the medium, under normal circumstances, without any thickening paste, or add a small amount of shift as the anti-bathing agent, and processing need to add the paste and dyes with modulated into a paste to prevent The outline of the pattern is unclear, or flower-shaped distortion up to less than a graphic design requirements, and to prevent migration of the dye after drying.

② The process different. Dyeing processing post-processing is usually a process of washing, soaping, drying, dyeing process, dye on the fabric has a longer duration of action, dyes can be more fully the penetration and diffusion within the fiber, so no other special post-processing, drying after paste will form a film, it prevents the dye to the penetration and diffusion within the fiber, and sometimes must resort to steaming to make dye from the paste is transferred to the fiber (ie, increasing the dye diffusion rate) to complete the coloring process, then the routine of washing, soaping, drying and other processes.

(3) mixed colors in different ways. Custom Car Flags Staining rarely mixed colors (except when dyed blend fabrics) with two different types of dyes, printed with colorful patterns, and sometimes will fail to meet requirements for a class of dyes, when often use different types of dyes common or with the paddle. In addition, and dyeing, there are many different points, such as semi-finished quality requirements are different, the same shades of color, printed with the dye than staining much greater, it is sometimes added cosolvent to help dissolve.

The dye or paint pattern printed on the fabric, there are many, but its main methods are the following.
Method is the direct , direct (1): the flower-shaped pattern of a variety of colors printed directly on the fabric in a variety of colors in the process, the paste does not occur to impede and undermine the role of Printed fabric, about 80% -90% using this method. This method can be printed white, flowers and
(2) discharge : stained with colored fabrics containing chemicals can destroy colored color paddle of such chemicals is called the discharge agent. Discharge paddle can also add dyes are resistant to chemicals. Such a discharge can be two effects pull pull white and color. Custom Car Flags
(3) resist : the first printed on the fabric to prevent dye uptake of the anti-agent, and then pad to color, printed patterns at to prevent the colored dye, the methods shall resist , the Act available to the three effects, anti-white, color defense, and some anti-pollution.
The how printed patterns affected by many factors, such as the requirements of the pattern, product quality requirements, the level of cost. Therefore, a pattern has been chosen we must consider the easiest way to use the premise of guaranteeing quality, lowest cost to printed.

As early as 2000 years ago, people had been woodcut or metal engraving technology used in textile . Our daily lives and come into contact with the seal, printmaking is a continuation of the technology of the Promotional Yard Flags of the convex plate . Sports jersey number printed cardboard class material and carved into the hollow of the pattern covered in fabric to brush the paste to form patterns in the type of board, of the method is also a long history of far Lou plate . These two kinds of methods has clearly can not meet the requirements of modern large-scale .
processing has a long history, many different types, but the total can be divided into two categories: flat-plate and circular. The flat-plate include: convex plate , engraving and plate , flat screen ; Custom Car Flags round include: roller , rotary screen . There are some, such as transfer , electrostatic flocking , photographic and inkjet and so on.
