General information on dyeing
Coloring is one of the most distinctive characteristics of a fabric, the manufacturing process that
gives color to a raw fabric is called dyeing.
Changing the color of raw fabric by dyeing significantly increases the economic value
of the fabric, so much so that this process has been the subject of great attention since ancient times.
The notable progress that has affected chemistry and technology since the end of the 19th century
they have revolutionized dyeing processes, both in coloring materials and technologies
and application methodologies. This transformation was also stimulated by the introduction of
new artificial and synthetic fibers that have characteristics and behaviors that are very different from those
natural fibres.
Let's now look at the most important industrial piece dyeing processes, referring to the type
of dyed fiber and the machine used.
