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 ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

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 3175-4:2003), which has been technically revised. It also incorporates the Technical Corrigendum ISO 3175-4:2003/Cor 1:2009. The main changes compared the previous edition are as follows:

• restriction of the scope to fabrics and garments that cannot be washed and need professional finishing;
• 6.1: addition of a reference to the technical specifications of the apparatus as described in ISO 6330 and withdrawal of the reference to Annex A;
• 9.1: clarification of the normal process steps;
• Table 1: updating of some settings in processes;
• Annex A: updating of some specifications of the tumble dryer (humidity control and cage outlet temperature);
• Annex B: withdrawal of the programming washing instructions, replaced by Table 1, and addition of an informative part dealing with an alternative procedure for Type C washing machines.

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

This corrected version of ISO 3175-4:2017 incorporates the following corrections:

— in 8.2, the test specimen dimensions have been corrected.

Introduction

Professional wetcleaning is used by professionals for cleaning textiles in water. It uses specialized equipment, programming, detergent and other additives to minimize adverse effects on textiles such as mechanical action and temperature. It is followed by drying and restorative finishing procedures, in most cases by steam treatment and/or hot pressing.

The professional wetcleaning process takes place without the intense mechanical action associated with washing.

Properties of the textile or garment can change progressively on professional wetcleaning, steaming and/or pressing. In some cases, a single treatment can give little indication of the extent of dimensional and other changes that can arise after repeated treatments and affect the useful life of the article. Generally, most of the potential change becomes apparent after three to five of the simulated professional wetcleaning and finishing treatments specified in this document. This progressive change should be borne in mind when determining the number of repeated cycles which is given (see Clause 4).

The properties that should be considered in an assessment for professional wetcleaning together with the methods for their assessment are given in ISO 3175-1.

1 Scope

This document specifies simulated professional wetcleaning procedures, using a reference machine for fabrics and garments. It is intended for fabrics and garments that cannot be washed and need professional finishing. It comprises a normal process for normal materials, a mild process for sensitive materials and a very mild process for very sensitive materials.

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

2 Normative references

The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.3

normal material

material that is able to withstand a normal simulated professional wetcleaning process (3.6)

Note 1 to entry: Normal material is related to the care symbol from ISO 3758:2012, Table 6.

3.4

sensitive material

material that is able to withstand a mild simulated professional wetcleaning process (3.7)

Note 1 to entry: Sensitive material is related to the care symbol from ISO 3758:2012, Table 6.

3.5

very sensitive material

material that is able to withstand a very mild simulated professional wetcleaning process (3.8)

Note 1 to entry: Very sensitive material is related to the care symbol from ISO 3758:2012, Table 6.

3.8

very mild simulated professional wetcleaning process

cleaning procedure in water at 30 °C followed by 2 min tumbler drying at 40 °C as a maximum and followed by air-drying

Note 1 to entry: See Table 1 for the requirements of this cleaning procedure.

Note 2 to entry: After giving careful consideration to the comments on progressive change in the Introduction, textile items that perform satisfactorily for purpose in the procedures intended for sensitive and very sensitive materials in Table 1 may be labelled as appropriate with the symbol.
