1. In Printing And Textile Industry (Leading Use)
(1). Printing Agent
It has been a long history that Sodium Alginate is used in starching, packing and printing, mainly in printing. As a reactive printing agent, it has a special property. During the chemical reaction of fibre and reactive dye,the dye is fixed fibre and printing agent does not attend this reaction. Otherwise, the agent will be fixed in the fibre and make it hard, fragile and bad color. If you use Sodium Alginate as a printing agent, it not only affects the dyeing reaction but also makes the product outline clear, color bright, feeling smooth. This agent is also suitable for cotton, wool, silk and synthetic fibre. The products of medium and low viscosity fit for the printing requirements by net or roll style. Actually the printing agent mixed with low-viscosity Sodium Alginate is stabler than with the other viscosity, which is the result to produce a high content of printing agent. This agent will make a dense cover during drying and raising dyeing.
(2). Synthetic Fibre
Mix Sodium Alginate and asbestos short fibre, then mixture solidify the by a solution of Calcium Acetate. This treatment can avoid Asbestos fibre of flying around to harm to health.
2. In Food Industry
As a stabilizer of ice cream replacing starch and carrageenan, Sodium Alginate can avoid of ice crystal and make the product tasty. It also applies to the mixed drinks, such as ice lolly, iced fruit juice and iced milk, etc. When adding some into dairy products like refined cheese, canned cream and dry cheese, the final product will not stick to the package. Moreover, Sodium Alginate can keep the product fine and avoid of splitting open if it is used as a cover of mild food.
