Color added at extrusion
Colors are typically resistant to
fading
Color offering is limited to about 125
colors
Solution dyed fiber CAN stain and

21. Types of Dyeing Methods
 Solution Dye
 Colorant is added to molten polymer
 Stock Dye
 Staple fiber is dyed before spinning
 Yarn Dye
 Yarn is dyed after it has been spun. Space dyeing is
a variation of yarn dyeing.
 Piece Dye
 Carpet is dyed after it has been formed
 Injection Dye - Millitron
 Pressurized dye solution is injected onto the face of
carpet with a series of small jets.

41. Fiber Shape (cross-section)
 Fiber shape is a cross section of a
single fiber. It results from the shape
of the holes in the spinneret when the
fiber is extruded. Manufactures
modify the shape to enhance
performance characteristics.
