Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 3175-2 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2,
Cleansing, finishing and water resistance tests.
ISO 3175 consists of the following parts, under the general title Textiles — Dry cleaning and finishing:
— Part 1: Method for assessing the cleanability of textiles and garments
— Part 2: Procedures for tetrachloroethene
— Part 3: Procedures for hydrocarbon solvents (under development)
— Part 4: Procedure for wet cleaning systems (under development)

Introduction
Dry cleaning is a process for cleaning textiles in an organic solvent that dissolves oils and fats and disperses
particulate dirt substantially without the swelling and creasing associated with washing or wet cleaning. Small
quantities of water may be incorporated in the solvent with the aid of a surfactant for the purpose of obtaining better
soil and stain removal. Some moisture-sensitive articles are preferably dry cleaned without the addition of water to
the solvent. A surfactant is often used to assist with soil removal and reduce the risk of greying, but it must be borne
in mind that surfactants contain varying amounts of water in their formulations.
Dry cleaning is normally followed by an appropriate restorative finishing procedure. In most cases, this comprises
some form of steam treatment and/or hot pressing.
Properties of the textile or garment may change progressively on dry cleaning and steaming and/or pressing and in
some cases a single treatment may give little indication of the extent of dimensional and other changes that may
arise after repeated treatments and which may affect the useful life of the article. Generally, most of the potential
change will become apparent after three to five of the dry cleaning and finishing treatments specified in this part of
ISO 3175.
The properties which should be considered in an assessment for dry-cleanability together with the methods for their
assessment are given in ISO 3175-1.

Part 2:
Procedures for tetrachloroethene
1 Scope
This part of ISO 3175 specifies dry-cleaning procedures for tetrachloroethene (perchloroethylene), using
commercial dry-cleaning machines, for fabrics and garments. It comprises a procedure for normal materials and
procedures for sensitive and very sensitive materials (see definitions 3.4 and 3.5).
NOTES
1 Various solvents can be used for dry cleaning, of which tetrachloroethene is the most common in many countries. For this
reason, the present method prescribes the use of tetrachloroethene.
2 When using commercial dry-cleaning equipment, official regulations and normal safety precautions should be observed.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this part of
ISO 3175. At the time of publication, the editions indicated were valid. All standards are subject to revision, and
parties to agreements based on this part of ISO 3175 are encouraged to investigate the possibility of applying the
most recent editions of the standards indicated below. Members of the IEC and ISO maintain registers of currently
valid International Standards.

3.4
sensitive materials
materials which may require restrictions as to mechanical action and/or drying temperatures and/or water additions
EXAMPLES Acrylics, silk, crepe
3.5
very sensitive materials
materials which may require greatly reduced mechanical action and/or greatly reduced drying temperatures and/or
no addition of water
EXAMPLES Polyvinylchloride (PVC), modacrylic, novelty tweeds, angora
NOTE — After giving careful consideration to the comments on progressive change in the introduction, textile items which
perform satisfactorily for purpose in the procedures intended for normal and sensitive materials in table 1 may be labelled with
the and symbols respectively, as described in ISO 3758. There is no care label equivalent to the procedure for very
sensitive materials and information on the required processing can only be given in words.
4 Reagents
4.1 Tetrachloroethene, CCl = CCl distilled, sold for the purpose of dry cleaning.
2 2
4.2 Sorbitan mono-oleate.
NOTE — In order to prevent foaming, it is important to use redistilled, clean solvent solution and not overfill the still.
5 Apparatus
5.1 Dry cleaning machine, consisting of a commercial reversible rotating cage type, totally enclosed machine
intended for use with tetrachloroethene, The diameter of the rotating cage shall 600 mm minimum and 1 080 mm
maximum. Its depth shall be 300 mm minimum. It shall be fitted with three or four lifters. The speed shall be such as
to give a g-factor between 0,5 and 0,8 for cleaning and between 60 and 120 for extraction.
NOTE — The g-factor is calculated according to the following formula:
2 –7
g = 5,6 n d · 10
where
n is the rotational frequency, in rotations per minute;
d is the rotating cage diameter, in millimetres.
5.1.1 The machine shall be fitted with the means to control solvent and air temperature as required (see table 1).
5.1.2 The machine shall have suitable facilities to allow the emulsion (see 8.1.3) to be introduced gradually into the
solvent between the cage and drum below the level of the solvent.
5.1.3 The machine shall be equipped with a means of measuring the temperature of the solvent during washing
and either
