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 ).

The committee responsible for this document is ISO/TC 38, Textiles.

Introduction

The thermal properties of textile materials contribute to a wearer’s physiological comfort, product's durability, etc. Hence, there are many kinds of products with specific thermal performances and various test methods that have been developed and standardized. However, these tests should be conducted in a certain humidity. The method for thermal properties in elevated or reduced humidity has not been standardized.

All materials generate heat when absorbing moisture and absorb heat when releasing moisture. The heat of absorption varies according to the material, for example, the heat of absorption in wool fibre is much bigger than that in common synthetic fibre. Recently, with this property, some heat-generating textiles have been developed and applied to various products, such as outdoor wear, sportswear, inner wear, special working wear, and healthcare wear. Therefore, the test for the hygroscopic and exothermic properties of textiles is needed for both producers and customers. Despite these needs, accurate and reliable information about hygroscopic and exothermic properties of textiles cannot be offered because of the absence of a standard test method.

The exothermic and endothermic properties of textiles under changing conditions of environmental humidity can be measured with this test method and apparatus proposed in this International Standard.

1 Scope

This International Standard specifies a method for the measurement of exothermic and endothermic properties by moisture absorption and desorption in sheet-like textiles, e.g. fabrics, knit or nonwovens for clothing, bedding, upholstery, and similar textile products.
