  At present, the traditional acid dyeing bath condition dyeing method is still used in the dyeing and finishing of polyester fabrics. The method has the disadvantages of poor quality, low output and high production cost in the production process, and it is more and more unsuitable for the production needs, especially for the dyeing of polyester fabrics after alkali treatment. The root of these problems lies in the lack of basic dyeing auxiliaries, while   sodium hexametaphosphate/SHMP technical grade   is a widely used dyeing auxiliaries in phosphate products. First, look at the advantages of basic dyeing aids: Basic dyeing auxiliaries, which are used as special dyeing auxiliaries for basic dyeing of polyester fabrics, popularize the basic dyeing methods. By optimizing alkali resistant disperse dyes and using special alkali agent, polyester fabric can be dyed and processed in alkaline condition, which can make the fabric bright in color, reduce defects such as color diff...

  Calcium carbonate is one of the most widely used inorganic fillers, which can be divided into two categories: heavy calcium and light calcium. The former is made of natural minerals (mainly limestone and calcite) after grinding, and the latter is obtained by chemical precipitation. With the development of technology, environmental protection and energy problems,   sodium hexametaphosphate/SHMP technical grade   has become a grinding aid to improve grinding efficiency and reduce grinding energy consumption. One of the reasons for the low output of heavy calcium is the lack of mature superfine grinding technology. Superfine grinding is a process of high energy consumption. How to reduce the energy consumption and improve the efficiency of superfine grinding is an urgent problem to be solved. Then Chongqing Chuandong Chemical Group, the manufacturer of sodium hexametaphosphate/SHMP technical grade, tells you that the use of grinding aid industrial grade sodium hexametaphos...
