Abstract
The present invention discloses a spin-dyed gradient-color fiber and a method for fabricating the same, wherein at least one component of the fiber is spin-dyed. The present invention obtains gradient color via controlling at least one of the following spinning conditions: (1) colorant quantity: continuously varying quantity of at least one colorant metered by colorant meters; (2) output ratio: continuously varying the output ratio of at least one melt extruder; (3) fineness: varying fineness of the fiber in a stretching way, a false-twisting way or another way.

A method for fabricating a spin-dyed gradient-color fiber, characterized in performing spin-dyeing in a melt extruder to spin-dye a monocomponent thermoplastic fiber or a multicomponent conjugate thermoplastic fiber containing at least two components, and continuously and periodically varying the output ratio of said melt extruder to provide gradient color for said thermoplastic fiber.
A method for fabricating a spin-dyed gradient-color fiber, characterized in respectively performing spin-dyeing in at least two melt extruders with identical colorants wherein at least one said extruder has a colorant concentration different to colorant concentrations of other said extruders to spin-dye a monocomponent thermoplastic fiber or a multicomponent conjugate thermoplastic fiber containing at least two components, and continuously and periodically varying a output ratio of at least one of said melt extruders to provide gradient color for said thermoplastic fiber.
A method for fabricating a spin-dyed gradient-color fiber, characterized in respectively performing spin-dyeing in at least two melt extruders with different colorants to spin-dye a monocomponent thermoplastic fiber or a multicomponent conjugate thermoplastic fiber containing at least two components, and continuously and periodically varying a output ratio of at least one of said melt extruders to provide gradient color for said thermoplastic fiber.
