This part of ISO 105 specifies a method for determining the resistance of the colour of wool textiles of all kinds to processes using chemical means in conjunction with steam for creasing,pleating and setting purposes.
A specimen of the textile (textiles from wool of all kinds), treated with the chemical solution, is placed in contact with specified adjacent fabrics and subjected to steam pressing. A comparison specimen, not treated with the chemical solution, is steam pressed simultaneously. The specimens are dried and any differences between the colour of the two specimens and the staining of the adjacent fabrics are assessed with the grey scales.
