In this regard, after reviewing the different reports provided by the applicant in the course of the investigation, it is noted that the experts distinguish two ways to dye PFF: either by dipping the yarn or the fabric itself in a colour bath (dyeing in surface) or by melting the colour within the polyester when the yarn is made (dyeing in the mass).
