Cautionary Notes:
Preparation of Textiles
To achieve ideal results, the fabric used for processing and finishing must be free of all processing aids, such as: wetting agents, dyeing auxiliaries, sizing residues, softeners, and other surfactants.
To avoid diminishing the effect, some mechanical treatments such as calendering, electro-polishing, and brushing can be done before drying and before baking; steam and steam-softening processes should be conducted after baking to enhance the finishing effect; fluffing and abrading should be done prior to the finishing process.
May affect the rubbing fastness of dyed and printed fabrics with disperse dyes. Recommend conducting a preliminary test.
Further processing services, such as garment washing/Film Coating/Coatings may affect stain management performance; it is recommended to conduct pre-testing to ensure these treatments do not impact the fabric's properties.
