SPEAKING generally, loosely woven fabrics take dye better than closely woven. Wool dyes more readily than cotton; and cotton more readily than silk. If a fabric is already dyed, but faded, it can be restored to its original colour or a darker tint. If a change of colour is desired, it must be to a darker shade than the original, to conceal it. Account must be taken of the original colour, as it may affect the colour given by the dye. A yellow dyed blue tends to green; a red dyed blue, to a purplish tinge.
On white and fine fabrics cold-water dyes may be used successfully where delicate colours are desired. For deep colours, or change of colour, hot-water dyes should be used. Cause of Uneven Dyeing A RTICLES to be dyed should have buttons, other fittings, trimmings, and linings removed, and any stitching undone which would hinder the dye reaching the back of the fabric. They must then be thoroughly cleaned, as any grease or dirt left in the fabric will cause uneven dyeing and may spoil the colour; and be placed in the dye while wet.
The dye solution should be sufficient to cover the article thoroughly in a vessel large enough to allow room for stirring. The correct mixing of the dye should, if possible, be arrived at by test on a sample of the fabric.
The addition of salt to the dye brightens up the colour of cotton goods. Articles Dry a Lighter Shade PHE vessel holding the dye should be suitable for heating over a gas-ring or stove, if boiling is needed.
The dye having been dissolved in hot water, the article is immersed and kept covered and moved about by a stick or wooden spoon. If stirring ceases at any stage, unevemiess of colour may result. Since the fabric will dry to a rather lighter shade than it was when wet, allowance must be made for this fact in deciding when steeping has gone far enough.
The article is then transferred with the stick (the hands should be kept out of the dye) to cold water, and rinsed repeatedly in changes till it ceases to tinge the water. It is then ready for drying. Should the tone prove not to be dark enough, a second immersion, in stronger solution, must be given.
The general advice given above will be amplified by the instructions issued with the particular dyes used. The last should be the products of the leading makers of dyes. Inferior, cheap dyes are dear at any price, except for the roughest of rough work.
