General Preparation of fibres for dye baths:
Washing temperatures:
• Ensure fibre is clean and free of grease, dirt, natural oils and chemical residues.
• Wet fibre thoroughly before mordanting or dyeing. It is a good idea to soak the fibres overnight in clear water – they should be submerged and able to move freely.
• Washing temperature – avoid sudden temperature changes. Never pour hot water straight from the tap or kettle. Introduce fibres to a tepid dye bath, and increase to simmer. Then reduce heat and return to room temperature.
• Silk is processed at a slightly lower temperature than wool. Cotton fibres are more resilient.
Washing Fibres:
• Squeeze gently. Do not rub or handle roughly.
• Use dishwashing liquid or a scouring agent such as Orvus paste. A scouring paste is pH neutral.
• For this project, Palmolive Dish Wash (DW) Soap was used to wash all samples.
