Procolour Dyeing Service

1. Fibre types, fabric weaves, and quantities dyed: Procolour dyes protein fibres like silk, wool, alpaca, angora, feathers  plus nylon, millinery raffia, and flax. Of the listed fibres, silk is the most popular, and Procolour specialises in silk dyeing. Which silks dye best? Evenly machine-woven, 'natural ivory', 'boiled off' silk gives the best dyeing results. Popular silk weaves that dye well are: Paj, Habotai, crêpe, crêpe satin, georgette, chiffon, jacquard, brocade, gauze, knit, velvet, and organza.  Avoid silks that have been hand-woven (uneven weaving tensions can cause uneven dye uptake). Also avoid silk fabrics that have been im- pregnated with 'optical whiteners' or other finishing chemicals. Problematic dyeing weaves are: hand-loomed Dupion, some tightly machine-woven twills, and heavy duchess satins. How much silk fabric can be dyed per batch in a continuous uncut length? It has been found through experience that silk fabric beyond 2 kg (dry weight) starts to become problematic and can yield uneven results. However, each fabric type has differing maximum dyeable lengths, largely determined by its weave and weight. Of course, there are no minimum dyeable lengths. Please ask for maximum length estimates, if required.
