ISO 105-C10 Textiles Tests for colour fastness

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.

 

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. 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.

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.ISO 105-C10 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants.ISO 105 was previously published in thirteen “parts”, each designated by a letter (e.g. “Part A”), with publication dates between 1978 and 1985. Each part contained a series of “sections”, each designated by the

respective part letter and by a two-digit serial number (e.g. “Section A02”). These sections are now being republished as separate documents, themselves designated “parts”, but retaining their earlier alphanumeric designations. A complete list of these parts is given in ISO 105-A01.

 

This first edition of ISO 105-C10 cancels and replaces ISO 105-C01:1989, ISO 105-C02:1989,

ISO 105-C03:1989, ISO 105-C04:1989 and ISO 105-C05:1989, which have been technically revised. 

 

Introduction

The test methods in this part of ISO105 are intended to reflect the effect of washing using soap or soap and soda by domestic andcommercial laundering procedures on the color of textiles.In this Test, a Specimen of Textile incontact with pieces of Adjacent Fabric (Standard Fabric) is mechanically agitated in a StandardSoap Solution (Sodium Oleate Solution), before being rinsed and dried. The change in Color ofthe Specimen and the Staining of the Standard Fabric are assessed with Standard Grey Scales.The Instrument used for this purpose is called Digital Washing Fastness Tester.

 

Principle

A specimen of the textile in contactwith one or two specified adjacent fabrics is mechanically agitated under specified conditionsof time and temperature in a soap, or soap and soda solution, then rinsed and dried. Thechange in color of the specimen and the staining of the adjacent fabric, or fabrics, are assessedwith reference to the original fabric, either with the grey scales or instrumentally.

 

Calculations:

Evaluation:

Change of color of the original color sample (color change) and the color of originally whitesample (color transfer - staining)6 Two possible principles:Measurement of color difference (not so common) and using of color-difference standards ?grayscales?(standard evaluation)

 

Grey scale:

One for ?color change ? testing and the second one for the ?staining?.
