IS 4636 : 1988 Method for determination of colour fastness of textile materials to dry-heat treatments (excluding pressing)

1 Scope

1.1 This standard prescribes a method for the determination of colourfastness of textile materials of all kinds and in all forms to the action ofdry-heat as employed in processes designed to give textiles stability ofdimensions or shape such as pleating and setting. It is mainly applicable tosynthetic fibres or textiles containing synthetic fibres.

1.1.1 Three tests differing in temperature are provided; one or more of themshall be used depending on the requirements and the stability of the fibres.

1.2 When this method is used for assessing colour change and staining indyeing, printing and finishing processes, it should be recognized that otherchemical and physical factors may influence the results.
