1. It is unstable viscosity if a normal gum of stock solution
is added to NaOH solution (Be, 45)
20%. But Na GUM has a good viscosity stability, fluidity
and penetration with NaOH solution.
2. Na GUM could melt only Polyester excluded Nylon for
mixed fiber during burnout because there is blended with
only small quantity of treatment without chemicals such
as auxiliarys as well as revelling agent etc.
3. There is no bleeding under printing because of molecule
bond. In particular, in the case of performing burn-out,
Na GUM could provide a sharpness on the fibers since dehydration
related to NaOH solution and thickening agent of stock solution
do not exist.
