云南11选5开奖结果Transfer paper production-transfer printing principle

Thermal transfer printing of clothing decorative cloth, curtain cloth, sofa, umbrella cloth, handbag, carpet cloth, toy cloth, etc.

Thermal transfer decoration on the surface of high temperature resistant plastic materials or plastic materials treated by spraying, baking paint, electrophoresis, etc.

After spraying, painting, electrophoresis and other treatments, the metal decoration board, anti-theft door, metal moulding door, aluminum profile, metal ceiling, curtain guide rail, metal pipe, handicraft, hardware furniture and other metal surface thermal transfer decoration.

The front and back of various natural leather.

Surface of PU or PVC, such as fabrics coated with PU or PVC, etc.

Transfer printing is not only suitable for synthetic fabrics, but also for natural fiber pure spinning and blended fabrics. It has the following advantages:

No water, no sewage;

The process flow is short, the finished product is printed, and the post-processing process such as steaming and washing is not needed.

Fine patterns, rich and clear layers, high artistry, strong sense of three-dimensional, printing for general methods, and can print photography and painting style patterns;

In the process of sublimation, the tar in the dye is left on the transfer paper, which will not pollute the fabric.

The rate of authenticity is high. When transferring, multiple sets of patterns can be printed at one time without any need for flower matching.

Flexibility, customers can choose patterns in a shorter period of time to print out.

Sublimation generally undergoes three processes: before the transfer process occurs, all dyes are in the paper film, the dye concentration in the printed fabric and air gap is zero, and the size of air gap depends on the fabric structure, yarn count and transfer pressure; during the transfer process, when the paper reaches the transfer temperature, the dyes begin to volatilize or sublimate, and the concentration between the paper and the fibers volatilizes. When the transfer temperature of the printed fabric reaches, dye adsorption begins on the surface of the fiber until a certain saturation value is reached. Since the transfer of dyes from paper to fibers is continuous, the adsorption rate depends on the rate at which dyes diffuse into the fibers. In order to make dyes diffuse directionally, vacuum is often pumped at the bottom of the dye to achieve directional diffusive transfer of dyes. After dyeing, the content of dyes on the paper decreases, and some of the remaining dyes migrate to the inside of the paper. The amount of residual dyes depends on the vapor pressure of dyes, the affinity of dyes to pulp or transfer paper and the thickness of printing film. Sublimation generally does not require wet treatment, which can save energy and reduce the burden of sewage treatment.
