Dyeing fabric ribbons is one of the most complex processes in ribbon manufacturing. The color of a ribbon is crucial to be uniform and replicable so that we can achieve the “same color” twice in two different manufacturing batches.<\/span><\/p>\n

It is never possible for one color to be exactly the same as another due to the complexity of the process (dyes, auxiliaries, temperatures, ribbon materials, pressures…), even though they may appear the same to our eyes.<\/span><\/p>\n

DYEING PROCESSES FOR FABRIC RIBBONS: TYPES<\/strong><\/p>\n

There are two dyeing processes for fabric ribbons: discontinuous and continuous.<\/span><\/p>\n

    \n
  1. Discontinuous System (Autoclave)<\/strong><\/li>\n<\/ol>\n

    The discontinuous system for dyeing fabric ribbons is carried out using a pressurized container with the ribbon wound on perforated cones. This requires a previous winding operation.<\/span><\/p>\n

    Once the container is filled with ribbon coils, the water solution with dyes and necessary auxiliaries is pumped through the holes of the coils containing the ribbon in both directions, from outside to inside and from inside to outside.<\/span><\/p>\n

    In this operation, time and temperature are crucial, requiring the skills of a color technician, although in more modern machines, these operations have also been automated.<\/span><\/p>\n

    For this entire process, a large amount of water and energy is needed because, during dyeing, both cold and hot water are required for washing the fabric ribbon.<\/span><\/p>\n

    In this dyeing mode, the drying and finishing of the ribbon are done with processes separate from the dyeing process we just explained.<\/span><\/p>\n

    This discontinuous process has several disadvantages:<\/span><\/p>\n
