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).

ISO 22195-1:2020(E)
Introduction

There is no doubt that dyeing plays the most important role in expressing the colour of clothes. Until

the invention of synthetic dyes capable of expressing diverse colours, materials obtained from nature

to dye fabric have been used. Typically, colourants were obtained from plants or various materials were

extracted from minerals or insects. When dyeing fabrics using materials derived from these natural

substances, it becomes necessary to identify which substances the colourant was derived from. In other

words, there has been a demand to confirm whether a fabric is dyed using a natural substance.

A test method is developed to identify which type of natural substances have been used.
