        Customer Case

        Textile / printing and dyeing

        Product introduction

        I、 Product name

        Carboxymethyl cellulose, carboxymethyl starch (CMC, CMS)

        Ⅱ、 character

        Appearance, dissolution and solubility

        This product is white or yellowish flocculent powder. It is nontoxic, odorless, tasteless,

        soluble in water, and soluble in glycerine when a small amount of water exists. It has good

        compatibility and synergistic effect with other water-soluble adhesives, softeners and resins

        ★ Hygroscopicity

        The equilibrium water content of CMC increases with the increase of D S value and

        air humidity, and decreases with the increase of temperature. When the room temperature

        and equilibrium humidity are 80%-85%, the equilibrium water content is more than 26%

        ★ Filmo genicity

        CMC films with high viscosity and high

        molecular weight have high strength an


        flexibility. Some water-soluble resins are

        used as crosslinking agents, and the mixed

        solution of CMC is used to cast the film

        After further drying and plasticizing treatment

        the film can become an insoluble product

        Water insolubility can also be obtained b

        treating the dried CMC with aluminum salt

        Viscosity and rheology

        At the same D S value, the viscosity

        increases with the increase of concentration

        decreases with the increase of temperature,

        and rises after cooling. When the ph value of

        1% CMC aqueous solution is 6.0-9.0, the viscosity is the highest, and when the pH value is<6or>11.5

        the viscosity begins to decrease The viscosity of CMC solution decreased with the increase of shear

        rate due to its excellent pseudoplasticity
