NATIONAL FOREWORD
This IndianStandard (part CO?) which is identical with ISO 105-CO? : 1999 'Textiles - Tests for
colourfastness - Part CO?: Colour fastness to wet scrubbing of pigment printed textiles' issued by
the International Organization for Standardization (ISO) was adopted by the Bureau of Indian
Standards on the recommendation of the Chemical Methods of Test Sectional Committee and
approvaloftheTextileDivisionCouncil.
This standard supersedes IS 11908 : 1986 'Method for determination of colour fastness of textile
fabricstowetscrubbing'.
Colourfastnessof dyedlprinted textile materials to various agencies during their further treatment or
actual useisanimportantperformancerequirement from the viewpoint of the user or consumer. The
various agenciestowhichtextile materialsmaybe subsequently subjected may include water,acids,
alkalis, organic solvents, washing, laundering, drycleaning, perspiration, light, gaseous fumes,
bleaching,rubbing,carbonizing,felting, etc andthe colour of textile materials should be fast tothese
agencies and should not change considerably. The colour should also not bleed and stain the
adjacent fabrics which are subjected to these agencies along with coloured fabrics. The colour
fastness propertyofcolouredtextilesis, therefore, measured in terms of colour fastness ratingswith
respect tochangeincolourandlorstainingofadjacentfabrics.
Since colourfastnessisone of the most important requirement for export of textiles, it is considered
essential that Indian Standards related to colour fastness are completely harmonized with
InternationalStandards.ThevariousIndianStandardsoncolour fastness testing, are,therefore,being
revised to align them with the corresponding International Standardsand are being published in
PartsAtoZ.
This standard is intended to test colour fastness of textile materials to domestic or commercial
laundering procedures used for normal household articles. Industrial and hospital articles may be
subjectedtosociallaunderingprocedureswhichmaybe severe insome respects.
ThetextofISOStandardhasbeenapprovedassuitablefor publication as an Indian Standard without
deviations. Certain conventions are, however, not identical to those used in Indian Standards.
Attention isparticularlydrawntothefollowing:
a) Whereverthewords'InternationalStandard' appear referring to this standard,theyshould

b) Co~ma (,) has been used as a decimal marker in the International Standards, while in

PART C07 COLOUR FASTNESS TO WET SCRUBBING OF PIGMENTTEXTILES
1 Scope
This part of ISO 105 describes a method for determining the colour fastness to wet scrubbinq of pigment dyed or
pigment printed textiles ofallkinds.
Thetest isnotapplicable toloose fibres.

3 Principle
The test specimen is immersed in a soap solution or detergentsolution, scrubbed for a specified time with a brush
thenrinsed and dried. The change incolourofthe testspecimenisassessedusing the grey scale.
4 Apparatus and reagents
4.1 Testing device, consisting of a means of wet scrubbing, moving to and fro in a straight line along a
100mm±10mm track on the test specimen with aforce of9,0N±0,2N, with approximatelyone complete to and
oOl
o fro cycle per second. The base board of the device islarge enough to clamp on a test specimen of not less than
QN 80mm x 250 mm.

width of scrubbinq of 55mm ±2mm.Other brushes similar to the brush described above may be used as long as
there isagreementbetween interestedparties and theparticularbrush used isreported.

5 Test specimen
5.1 If the textile to be tested is a fabric, prepare one specimen not less than 80 mm x 250mm, with the long
direction parallel tothe warp yams(or the directionof manufacture). Ifmulticolouredtextilesare to betested and all
colours on the textile cannot be included in one specimen, prepare further test specimens and assess each colour
separately.
5.2 If the textile to be tested is yam or thread.knit it into fabric to provide a specimen at least 80 mm x 250 mm.
Theknitconstructionshouldbeagreedon betweenthe interestedpertcs.Ntematively, the yarn can bewound on a
