FZ/T 01071-2008Textiles - Test method for capillary effect (English PDF)

Foreword

This Standard refers to the "Liquid wicking rate" content in ISO 9073-6.2000 "Textiles

-- Test methods for nonwovens -- Part 6.Absorption" and revises FZ/T 01071-1999 "

Wicking Textile Test Methods".

Compared with FZ/T 01071-1999, this Standard mainly modifies the following

technical contents.

1) The scope of application has been modified;

2) The terms and definitions of "liquid wicking height" and "liquid wicking rate"

have been added;

3) "Distilled water" has been changed to "tertiary water";

4) The test liquid temperature of 27°C±2°C has been changed to equilibrium under

standard atmosphere;

5) The test liquid has been changed from 0.5% potassium dichromate solution to

tertiary water. Notes on the use of colored reagents have been added;

6) The test time series of 1 min, 5 min, 10 min, 20 min and 30 min have been added;

7) The calculation of the average value of the minimum seepage height has been

changed to the calculation of the average value of the maximum value and (or)

the average value of the minimum value;

8) The method of drawing the t-h curve and calculating the liquid wicking rate at a

certain moment has been added;

9) The rapid test method in Annex A has been deleted.

This Standard shall replace FZ/T 01071-1999 from the date of its implementation.

This Standard was proposed by China National Textile and Apparel Council.

This Standard shall be under the jurisdiction of Subcommittee on Basic Chapter of
