Colorants in nylon fiber

Abstract

Pigment compositions and fibers may include a single pigment component comprising a cobalt titanium oxide complex or a tin titanium zinc oxide complex. The pigment compositions may additionally include one or more additives having compatibilizer, adhesion promoting, and/or dispersion aiding capabilities, and a carrier resin.

What is claimed is: 
     
         1 . A pigment composition comprising:
 a single pigment component comprising i) a cobalt titanium oxide complex or ii) a tin titanium zinc oxide complex;   one or more additives having compatibilizer, adhesion promoting, and/or dispersion aiding capabilities; and   a carrier resin.   
     
     
         2 . The pigment composition of  claim 1 , wherein the single pigment component is the i) cobalt titanium oxide complex, and wherein the single pigment component confers a blue-green hue to the pigment composition. 
     
     
         3 . The pigment composition of  claim 1 , wherein the single pigment component is the ii) tin titanium zinc oxide complex, and wherein the single pigment component confers an orange hue to the pigment composition. 
     
     
         4 . The pigment composition of  claim 1 , wherein the carrier resin is a nylon, polyethylene, or polyethylene terephthalate resin. 
     
     
         5 . The pigment composition of  claim 1 , wherein the pigment composition exhibits improved end use properties comprising DE less than or equal to 2.00 in weathering at 200 hours. 
     
     
         6 . The pigment composition of  claim 1 , wherein the pigment composition exhibits improved end use properties comprising gray scale 4.00 or above for Rotowash 2A Test Cycle. 
     
     
         7 . The pigment composition of  claim 1 , wherein the pigment composition exhibits improved end use properties comprising gray scale 4.00 or above for wet & dry crock. 
     
     
         8 . The pigment composition of  claim 1 , wherein the pigment composition exhibits improved end use properties comprising gray scale 4.00 or above for heat stability in Nylon. 
     
     
         9 . A method of making the pigment composition of  claim 1 , comprising:
 mixing the single pigment component, the one or more additives, and the carrier resin;   feeding the mixture into an extruder;   processing the mixture through the extruder at a melt temperature; and   pelletizing the extrudate through strand or under water pelletizing.   
     
     
         10 . A fiber comprising:
 a single pigment component comprising a i) cobalt titanium oxide complex or ii) a tin titanium zinc oxide complex;   one or more additives having compatibilizer, adhesion promoting, and/or dispersion aiding capabilities; and   a carrier resin.   
     
     
         11 . The fiber of  claim 10 , wherein the single pigment component is the i) cobalt titanium oxide complex, and wherein the single pigment component confers a blue-green hue to the pigment composition. 
     
     
         12 . The fiber of  claim 10 , wherein the single pigment component is the ii) tin titanium zinc oxide complex, and wherein the single pigment component confers an orange hue to the pigment composition. 
     
     
         13 . The fiber of  claim 10 , wherein the carrier resin is a nylon, polyethylene, or polyethylene terephthalate resin. 
     
     
         14 . The fiber of  claim 10 , wherein the fiber exhibits improved end use properties comprising DE less than or equal to 2.00 in weathering at 200 hours. 
     
     
         15 . The fiber of  claim 14 , wherein the fiber exhibits improved end use properties comprising gray scale 4.00 or above for Rotowash 2A Test Cycle. 
     
     
         16 . The fiber of  claim 15 , wherein the fiber exhibits improved end use properties comprising gray scale 4.00 or above for wet & dry crock. 
     
     
         17 . The fiber of  claim 16 , wherein the fiber exhibits improved end use properties comprising gray scale 4.00 or above for heat stability in Nylon. 
     
     
         18 . A method of making the fiber of  claim 14  comprising:
 mixing the single pigment component, the one or more additives, and the carrier resin; 
 feeding the mixture into a fiber line; 
 processing the mixture through an extruder at a melt temperature; 
 drawing a 4:1 extrudate through godets; and 
 collecting the fiber on a spool. 
 
     
     
         19 . The pigment composition of  claim 1 , wherein the carrier resin is polyethylene terephthalate and wherein the pigment component confers a black hue to the pigment composition. 
     
     
         20 . The fiber of  claim 10 , wherein the carrier resin is polyethylene terephthalate and wherein the pigment component confers a black hue to the fiber.
