GB/T 5558-2015Surface active agents—Evaluation of wetting agents for mercerization (English PDF)

3.1 Mercerized

Natural cellulose in concentrated sodium hydroxide solution and puffing, to achieve physical properties of the irreversible process of change.

3.2 Wetting agents

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.

5.1 General

Test water to comply with GB/T 6682-2008 the provisions of tertiary water.

5.2 sodium hydroxide solution

Chemically pure, 271g/L ~ 299g/L (standing configured to clarify clarification from the upper part).
