Description
Product Name: Textile Grade Carboxy Methyl
Cellulose(CMC)
Product Description:
CMC appears to be white or light yellow powder, which is
odorless and non-toxic. It is soluble in cold or hot water. When it
solutes, some colloidal solution will appear, which is neutral or
slightly alkaline. The important feature of CMC is that it can form
colloid solution with high viscosity. Many factors influencing its
viscosity are concentration, PH, temperature, substituted ratio and
salts, etc.
Performance and Characteristics of Products:
a) Appearance: White or light yellowish fiber powder or white
powder with characteristics of odorless, tasteless and
non-toxic.
b) Solubility:
- Soluble in cold or hot water to form a gel, the solution is
neutral or slightly alkaline.
- Insoluble in ethanol, ethyl ether, isopropyl alcohol,
acetone and other organic solvents.
- Soluble in ethanol or acetone solution of *0%
moisture.。
- Physical Property: Hygroscopicity and stability to
heat and light.
- Viscosity: Viscosity decreases with temperature
increase.
Solution PH value:
Stable when solution PH value arranged 2 to *0;
Solid precipitates when solution PH less than 2;
Viscosity reduce when solution PH higher than *0;
c) Color-change Temperature: **7℃
d) Carbonization Temperature: **2℃
e) Surface Tension: *1 mn/n in 2% aqueous solution.
Application:
Textile, printing and dyeing industry
Used as sizing agent to be applied to light gauze of cotton,
silk and wool , chemical fiber, blended and other
materials.
As fabric finishing agent, CMC can replace starch slurry, reduce
the pollution to the environment in the fabric sizing and desizing,
form a thin film on the fabric; CMC film with moisture absorption,
increased the plastic fabric, reduce yarn "jump" on high speed
loom, the phenomenon of yarn faults.
