Perspiration light fastness improver PLF
The colour fastness to light and perspiration is the resistance of the colour of the textile to the combined effects of human sweat and sunlight during the consumption process. It is common in the fading problem of reactive dyes (especially in light and medium colours) under light and perspiration combined conditions. It reflects that many reactive dyes still have insufficient colour fastness to perspiration.
Light and sweat composite colour fastness improver PLF is mainly suitable for the dyeing of various natural fibres and synthetic fibres. The improvement of the colour fastness to sweat can increase the lightfastness of the processed fabric by 0.5-1 level. Besides, the colour and feel of the treated textiles have little effect.
