Requirements on pigment printing adhesive
In order to solve the core issues of the feel, color fastness and environment of pigment printing, the environmentally friendly printing binder is synthesized. Heat Sink Paste must meet the following requirements: the formed film is colorless and transparent and it will not become yellow after heating. The nature of the film is sturdy with good elasticity, adhesion, washable and dry cleaning and resistant to the sun and aging; film-forming is soft, feel good and not tacky after the treatment of fabric. The color fastness of printing fabric is not less than the dye printing standards.
The important role of heat sink paste
Pigment printing process is simple, saves energy, with chromatography and no wastewater discharge. Mixed colors and spline are convenient, printing outline is clear, genuine rate is high, reproducibility is strong and general light fastness is good. In recent years, many new materials can be used in pigment printing process, especially with the development of synthetic fiber and blended fabric, the superiority and the importance of the pigment printing are more prominent. Today's global pigment printing takes the average share of the total printing market share of 45% and it takes the largest proportion of all printing. Among them, ratio of upholstery fabrics is 38%. However, pigment printing printed fabric has low rubbing fastness and it will release odor in the operating environment. Although countries in the world have spared no effort to improve and develop new coatings for many years and make great progress in their supporting new additives, such as adhesive sealant, it is difficult to get the overall balance in feel, fastness, seepage, environmental protection and other aspects.
Development and status quo of the pigment printing binder
In the 1950s, the rapid rise in petrochemical and polymer science has spawned a wide variety of synthetic polymer binder. As the shortcomings of complex traditional dyeing process, various rejects, high cost and long processing cycle, foreign countries put forward pigment dyeing and printing. From the direction of development to improve the fastness, improve feel, and reduce energy consumption, foreign adhesives mainly have gone through four stages: the first generation of adhesives is not cross-linked polymer film-forming substances. The second generation was added -CN,-OH,-NH2,-COOH reactive group; the third generation was added self-crosslinking monomer in the binder component in order to improve fastness, reduce curing temperature and shorten the baking time. The fourth-generation printing binder - low-crosslinking binder appeared soon. The crosslinking molecular structure has a strong reactive group, and can react with the hydroxyl group or an amino group at 100 degrees Celsius and can improve the deposition, but also greatly save energy. China also made a lot of research in improving the adhesive application performance and exploring new synthesis process.

Thanks to the seven-year arduous pioneering, Conor has marched into the stage of rapid development. Confronting to the domestic competition of adhesive, the company takes slow and steady efforts to catch up and now it has created a well-known brand among the domestic adhesive industry.
