Silk is a very light natural fiber made by the silkworm.  It is the strongest natural fiber known and makes for a luxurious soft-smooth fabric with excellent insulating properties in both cool and warm conditions.  Orco Milling™, Orco Nylosol™, Orcolan Neutral™ and OrcoSet™ dyes provide bright and washfast colors on silk by both dyeing and printing processes.

Orco Milling™ Acid Dyes for Silk

Orco Milling™ dyes are characterized by their high wetfastness and their wide range of bright colors. Although their lightfastness falls somewhat short of the metallized group of acid colors they do offer a brighter shade range to choose from. These dyes are used primarily in stock and package dyeing but have been used in piece dyeing where careful temperature and pH control is possible.

Orcolan Neutral™ Acid Dyes for Silk

Orcolan Neutral™ dyes for silk, 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 (Cr+3 usually), these dyes exhibit excellent light and wet fastness properties.

Orco Nylosol™ Acid Dyes for Silk

Orco Nylosol™ dyes for silk are characterized by their excellent leveling and penetrating properties 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, when selected carefully and after-treated properly, good fastness may be achieved. This class of dye consists of two groups, each having somewhat different affinity for silk 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.
