3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Mercerized mercerization
Natural cellulose in concentrated sodium hydroxide solution and puffing, to achieve physical properties of the irreversible process of change.
3.2
Wetting agents wettingagent
A chemical that when added to water, the liquid can reduce the surface tension and interfacial tension between the liquid and solid.
Principle 4
The predetermined amount of mercerizing wetting agent is dissolved in the bath a certain concentration of sodium hydroxide solution, and the specific specifications of the wafer into cotton canvas measured
On the surface of the test solution, recording the time required for complete wetting.
Wetting agent were measured standard sample and the sample three different concentrations of wetting time, wetting time rendering - the concentration of a single logarithmic curve, curve comparison
Relative position determining wetting agent wetting force. Or relative wetting force, wetting time (s) to express mercerized bath wetting properties of the wetting agent.
