What is Dye?
'''Dye''' is a [[substance]] used to [[color]] materials. It is often used to color the [[fabric]] used to make [[clothing]]. It has low [[solubility]]. A [[pigment]] won't do this because it won't stick to the [[fiber]]s of the fabric and color them. A dye can be natural, usually made from plant material such as berries, or a dye can be artificial, meaning that it is made by humans from chemicals such as [[petrochemical]]s. Most natural dyes are gotten from different parts of a [[plant]] like the [[Root|roots]], [[Fruit|fruits]], [[bark]], [[Leaf|leaves]], [[wood]], [[Fungus|fungi]] and [[Lichen|lichens]].<ref>{{Cite book|url=https://www.worldcat.org/oclc/667210526|title=Harvesting color : how to find plants and make natural dyes|last=Burgess, Rebecca, 1977-|date=2011|publisher=Artisan|others=Green, Paige|isbn=978-1-57965-425-2|location=New York|oclc=667210526}}</ref> Most dyes are synthetic and are made from petrochemicals.<ref>{{Cite book|url=https://books.google.com/books?id=_F4hAwAAQBAJ&dq=organic+dye+laser&pg=PA539|title=Laser Fundamentals|last=Silfvast|first=William T.|date=2008-07-21|publisher=Cambridge University Press|isbn=978-1-139-85557-0|language=en}}</ref> ==Classification== Dyes can be classified based on their [[solubility]] and chemical properties. * [[Acid dye]]s can dissolve in water. They are used on [[fiber]]s such as [[silk]], [[wool]], [[nylon]]. Most [[food coloring]] that are made by man are acid dyes. Examples of acid dye are Alizarine Pure Blue B, [[Acid red 88]], etc. * Basic dyes can dissolve in water. They are mainly used on [[acrylic]] fibers. They may also be used on wool and silk. Basic dyes are also used to make [[paper]] colourful. == Related pages == *[[Pigment]] *[[Food coloring#Natural food dyes]] *[[Hair coloring]] ==References== {{Reflist}} [[Category:Color]] [[Category:Cloth]] {{stub}}
