Orco Milling™ dyes are characterized by their high wetfastness on nylon and wool textiles and their wide range of bright colors. Although their lightfastness falls somewhat short of the metallized group of acid dyes, they do offer a brighter shade range to choose from. These dyes are used primarily in textile stock and package dyeing but have been used in piece dyeing where careful temperature and pH control is possible. These dyes can also be used in other non-textile applications such as select detergent and coating formulations.

Orcolan Fast™ dyes are 1:1 acid metalized chrome-complex acid dyes with excellent leveling properties on wool in strongly acid conditions. Although this line is somewhat limited in shade range it is very popular due to its ease of application and good fastness properties and finds wide use in textile stock dyeing especially in those areas destined for cross dyes. This class is also applicable to non-textile applications.

Orcolan Neutral™ dyes are 2:1 premetalized acid dyes. Because of their large molecular size, these behave similarly to the Orco Milling™ dyes in application and strike rate. Because of the metal complex, typically Cr+3, these dyes exhibit excellent light and wet fastness and find application in automotive industrial fabrics as well as other non-textile applications such as anodized aluminum.

Orco Nylosol™ dyes are characterized by their excellent leveling and penetrating properties on nylon in addition to their wide range of bright colors. Although this range does not exhibit the high wet and light fastness properties of the Milling and Metallized dyes on nylon, when selected carefully and after-treated properly, good fastness may be achieved. This class of dye consists of two groups, each having somewhat different affinities and requiring slightly different application methods.

Actual dye samples must be evaluated in a laboratory on medium to be dyed in production for accurate shade and physical property results. Shades shown on print material and computer monitors are for general reference only as they are inherently inaccurate due to calibration variations and technical limitations of monitors and printers.
