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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

This document was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2, Cleansing, finishing and water resistance tests.

This second edition cancels and replaces the first edition (ISO 3175-3:2003), which has been technically revised. It also incorporates the Technical Corrigendum ISO 3175-3:2003/Cor. 1:2009.

The main changes compared to the previous edition are as follows:

• the consistency in the structure of ISO 3175-2 and ISO 3175-3 has been improved;
• 6.1.4, an automatic solvent dryness control of the drycleaning machine has been added;
• Clause 7, clarification about the test specimen conditioning and the standard atmosphere has been made;
• Clause 8, clarification about the test specimen preparation has been made;
• Table 1, the drying temperature for normal and sensitive materials in relation to the solvent flashpoint has been changed and “5 min minimum until the temperature is lower than 45 °C” has been added for deodorization time.

A list of all parts in the ISO 3175 series can be found on the ISO website.

This corrected version of ISO 3175-2:2017 incorporates the following corrections:

• 8.2, the test specimen dimensions have been corrected.

Introduction

Drycleaning 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 wetcleaning. Small quantities of water may be incorporated in the solvent with the aid of a detergent for the purpose of obtaining better soil and stain removal. Some moisture-sensitive articles are preferably drycleaned without the addition of water to the solvent. A detergent is often used to assist with soil removal and reduce the risk of greying, but it should be borne in mind that detergents contain varying amounts of water in their formulations.

Drycleaning 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 drycleaning 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 drycleaning and finishing treatments specified in this document. These progressive changes should be borne in mind when the interested parties determine the number of repeat cycles which is given.

The properties which should be considered in an assessment for drycleanability with the methods for their assessment are given in ISO 3175-1.

1 Scope

This document specifies drycleaning procedures for hydrocarbon solvents, using commercial drycleaning machines, for fabrics and garments. It comprises procedures for normal and sensitive materials (see 3.3 and 3.4).

Localized staining and stain removal fall outside the scope of this document.

material (3.1) consisting of all component parts which is able to withstand the normal drycleaning process as specified in this document, without modification

Note 1 to entry: Giving careful consideration to the comments on progressive change described in the Introduction, textile items tested in the procedures intended for normal materials in Table 1, and which perform satisfactorily in the assessments described in ISO 3175-1, may be labelled with the symbol, as described in ISO 3758.

3.4

sensitive material

material (3.1) consisting of all component parts which may require restrictions as to mechanical action and/or drying temperatures and/or water additions

EXAMPLES Fibre type: acrylic, modacrylic, silk, angora. Fabric type: crepe.

Note 1 to entry: Giving careful consideration to the comments on progressive change made in the Introduction, textile items tested in the procedures intended for normal and sensitive materials in Table 1, and which perform satisfactorily in the assessments described in ISO 3175-1, may be labelled with the symbol, as described in ISO 3758.
