1. Some terms and definitions should be known before dyeing

Today I will present some 'terms and definitions' which are essential for dyeing. I think the post will assist you and be effective to develop your knowledge & skills. Two posts needed to complete the task. First one is today, second will be published next.

AATCC : American Association of Textile Chemists and Colorists.

Alginate : A thickener used in textile printing for the paste containing dye.

Affinity : Attraction between the dye and fibres.

Anhydrous : A substance which contains no water or without water.

Antichlor : A chemical used to neutralize chlorine bleach.

Anti foaming agent : An agent used to protect the dye solution from forming foam.

anti-migrant : An additive used to prevent undesired movement or spread the wet dye on fabric.

Binder : A material like gum or glue nearly colorless, that is used to attach a pigment to fabric.

Carbonizing : Treatment of wool with acid and heat to remove vegetable, burrs, other materials.

cloud point : The temperature at and above which a water soluble component will precipitate from solution.

crocking : Transfer of color from dyed or pigmented fabric onto other white fast fabric by rubbing.

Defibrillation : Process to remove fibrils from the surface of a fabric.

Diluent : Deluent or dilutant is a solid or liquid chemical used to carry or dilute anything.

Electrolyte : A substance that makes an electrically conductive solution when it is dissolved in water.

Etchant : In textile terms, a chemical that is used to break down fibres so that they can be removed for purposes of patterning.

Exhaustion : The transfer of dye from dye bath to fibre.

Fastness : The resistance of a textile material to specific chemical agencies.

Fixation : Build up the “final” bond between the dye and fibre

hydration number : A value indicating how many water molecules are associated with each molecule of some other compound in a crystal of that compound.

Hygroscopic : Having a tendency to absorb water or moisture from air.

Indigo : A natural or synthetic Vat dye derived from the plant Indigofera tinctoria.

leveling agent : An ionic, non-ionic surfactant used to promote level dyeing.

Mercerization : treatment of cotton yarn or fabric with a strong solution of NaOH to increase its strength.
