Part 17
COLOUR FASTNESS TO HOT PRESSING
1. PURPOSE AND SCOPE
This method is intended for assessing the resistance of the colour of textiles of all kinds and in all forms to ironing
and to processing on hot cylinders.
Tests are given for hot pressing when the textile is dry, when it is wet and when it is damp. The end use of the
textile usually determines which test should be made.

ISO/R 1 OS/l- 1959/A4-1975 (E)
2. PRINCIPLE
The specimens are pressed with a heating device of specified temperature and mass for a specified time
2.1 Dry pressing. The dry specimen is pressed.
Damp pressing. The dry specimen is covered with a wet undyed cotton cloth and pressed.
2.2
2.3 Wet pressing. The upper surface of the wet specimen is covered with a wet, undyed cotton cloth and pressed.
2.4 The change in colour and the staining of the undyed cloths are assessed with standard grey scales immediately
and again after a period of exposure to air in the standard atmosphere.
3. APPARATUS AND REAGENIS
3.1 Heating device, providing even heat transfer to the specimen from the top by close contact at a controlled
temperature (see clauses 7.1 and 7.2) and giving a pressure on the specimen of 4 f 1 kPa* (see clause 7.4).
3.2 A smooth asbestos sheet of thickness 3 to 6 mm (see clause 7.2 and 7.3).
3.3 Undyed flannel of mass per unit area approximately 260 g/mZ. Two layers of this material are used to make
a pad of thickness approximately 3 mm. Similar smooth wool fabrics or felt can be used to give a pad of
thickness approximately 3 mm.
An undyed, bleached and unmercerised cotton cloth, of mass per unit area 100 to 130 g/m2 and with a
3.4
smooth surface.
Grey scale for assessing change in colour and staining of the undyed cloths**
3.5
4. SPECIMEN
4.1 If the textile to be tested is fabric, use a specimen 100 mm X 40 mm
4.2 If the textile to be tested is yarn, knit it into fabric and use a piece 100 mm X 40 mm, or wind it closely
round a piece of thin inert material measuring 100 mm X 40 mm to form a layer having only the thickness
of the yarn.
4.3 If the textile to be tested is loose fibre, comb and compress enough of it to form a sheet 100 nim X 40 mm
and sew the sheet on a piece of cotton cloth to support the fibre.
5. PROCEDURE
The following temperatures are used (see clause 7.1)
5.1
110 f 2 “c
150 f 2 OC
200 f 2 “c
When necessary, other temperatures may be used, provided they are specially noted in the report.
5.2 Specimens of materials that have been subjected to any heat or drying treatment must be allowed to
condition in the standard atmosphere for testing textiles***, i.e. 65 f 2 5% relative humidity and a temperature
of 20 f 2 OC, before they are tested.
* 1 kPa = IO3 N/m2 10 gf/cm*
