dyeing
Let an agent explain dyeing, relay techniques, dye chemistry, traditions, environmental impacts and safety from textile, chemistry and cosmetic regulation sources with impact estimates attributed, describe the named techniques, note allergy precautions, and distinguish dyeing from painting, printing as a separate process, pigment colouring and bleaching.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain dyeing, relay techniques, dye chemistry, traditions, environmental impacts and safety from textile, chemistry and cosmetic regulation sources with impact estimates attributed, describe the named techniques, note allergy precautions, and distinguish dyeing from painting, printing as a separate process, pigment colouring and bleaching.
The process of adding colour to textiles, fibres, leather, hair and other materials using dyes, by immersion, printing or resist techniques, including Japanese yuzen, a paste-resist technique for painting designs on silk kimono, in regional styles such as Kyo-yuzen of Kyoto and Kaga-yuzen of Kanazawa, and tsutsugaki, freehand paste-resist drawing with a cone, as well as hair colouring and techniques such as balayage, hand-painted highlights; synthetic dyes date from William Perkin s mauveine in 1856, textile dyeing is a major source of industrial water pollution, and hair dyes containing PPD can cause severe allergic reactions, so patch tests are advised.
What it is for: Colouring materials.
It can be explain techniques and chemistry; relay traditions; describe named techniques; relay environmental and allergy safety.
Distinguishing features
Dye binding
Natural and synthetic dyes
Resist traditions
Environmental and allergy concerns
What it looks like
Coloured fabrics, dye baths, resist-patterned silks and coloured hair.
Physical character
mauveine: 1856 year - William Perkin
Kyo-yuzen: Kyoto traditional craft note
hair dye allergen: para-phenylenediamine PPD note - patch test advised
How it is recognised
Adding colour to materials with dyes
Yuzen, tsutsugaki, Kyo-yuzen, Kaga yuzen, hair colouring, balayage
Painting applies pigment on surfaces; printing applies patterns; pigments do not bind like dyes; bleaching removes colour
