What is dye made of?
Modern dyestuffs are of a synthetic nature and are usually derivatives of coal tar.
What effect do dyes have on the environment?
The quantities used in a domestic situation have minimal concentrations and produce no adverse effects on the environment. They are quite safely disposed of down the drain.
Are dyes toxic?
Gold Cross dyes have a low toxicity (serious injury is unlikely unless large amounts are consumed). Dyes must not be inhaled or taken.
Will containers used during dye process stain?
Containers will generally not permanently stain. If residual colour remains, wipe our with a weak bleach solution. Nylon bowls and wooden spoons may retain some colour if used.
How do you remove dye from hands/skin?
Always wear protective gloves. If dye does stain skin wash with soap and water or remove with light bleach solution (colour will fade).
What are the differences between Gold Cross High Temp & Low Temp Dye?
High Temp Dye requires the introduction of heat to set the dye into material. Low Temp Dye works as a chemical reaction caused by the addition of setting agent. They are a different dyestuff.
Which dye is most suited to individual fabrics?
High Temp Dye is most effective on Cotton, Rayon, Hemp, *Nylon and *Wool (*with the addition of vinegar).
Low Temp Dye is designed for cellulose fibres only. They are suitable for Cotton, Rayon, Hemp and Tencil)
How many colours are in the Gold Cross range?
The Gold Cross High Temp range comes in 30 colours and the Low Temp Dye is available in 29 colours.
Can dye be mixed to obtain individual colours?
Yes! All of our dye is fully blendable within the individual ranges. You cannot mix High and Low Temp dyes together.
Are Gold Cross Dyes colourfast?
All garments fade with exposure to UV light and long-term washing; however when instructions are correctly followed dyed fabrics will exhibit normal colourfastness.
Can dye cover bleach marks or stains?
Bleach attacks the fibres within the garment and effects the way it will absorb dye in this region. Normally the patch will appear lighter. Depending on the type of stain the dye absorption may also be inhibited. Always prepare garments before dyeing to remove stains.
Why would the dyed garment appear streaked or blotchy?
The two most obvious reasons for this occurrence are 1) lack of agitation during dyeing process causing pockets or folds of colour; 2) finishes on garments that inhibit dye absorption e.g. waterproofing, scotchguards or size. Always thoroughly wash garment before dyeing even if new.
To increase depth of colour can I use less water?
To a degree this will work however you must always use enough water to allow garments to move freely in dye bath. Extra dye will increase depth of colour.
What does adding salt achieve?
Salt opens fibre to assist dye absorption, this is especially important in low temp dyeing.
When is vinegar used and what does it do?
Animal fibres such as wool, silk and nylon (synthetic wool) require acid to make the dye fix to the garment. Vinegar is the most readily available acid.
How does setting agent assist Low Temp dyeing?
Setting agent produces the caustic reaction that makes the dye set in the material.
What does Gold Cross Stripper do?
Stripper may be used to remove stains and prepare fabric for dyeing. It will also remove Hight Temp Dye (for re-dyeing). Not recommended for Low Temp Dye.
Can coloured fabrics be over dyed?
Yes, however the original garment colour will always affect subsequent colour. Original colour will need to be even, light and stain free.
Can I dye “Dry Clean Only” garment?
It is important when dyeing to always follow the fabric care label. If a garment can not be washed in hot water it can not be dyed in hot water.
Why did the colour come out lighter than indicated?
There are three obvious reasons why this can occur. 1) Not enough dye for weight of fabric or quantity of water used. 2) Incorrect water temperature – high temp dyes, in particular the dark colours, require boiling to produce a strong colour. 3) Recommended amount of salt or vinegar was not included in dye bath.
Why are dyes permanent?
Dyes are permanent because a chemical bond forms between the dye and the fibres.
How do I dye my garment in 250ml of water as it says in the instructions?
You can’t! This question is often asked by people who have failed to read the instructions correctly (refer instructions on High Temp dye). Remember – always read the instructions fully before attempting to dye.
Why do dark colours never seem to come out as dark as they are on the lid?
This is one of the most common problems encountered by the domestic dyers. The main reasons are as follows:-
High Temp Dyes:
All of these dyes especially black, navy, violet, maroon and other dark colours in the range, require boiling when being dyed to get the full strength colour. Darker colours need this heat for a longer period of time (about 40min) to be successfully introduced into the garment. Other possible causes for this result are not using enough dye for the weight / fibre of garment or when a polyester content is in the garment.
Low Temp Dyes:
With the Low Temp range the most common reason for the lack of depth of colour in the garment is due to the required amount of cooking salt not being added to the dye bath. Remember for dark colours always add 250g salt to the dye bath. 125g salt is sufficient for lighter colours It is also important to realise that with Low Temp dye the colour and fastness of the darker colours may be improved with the addition of an extra 25g Setting Agent (available separately). This is especially important with black, violet and navy.
