摘要
(US9469923) A method of producing synthetic yarn having copper properties is described.  The method providing: applying a copper additive to a partially oriented yarn (POY) during one or more finishing processes of the POY to produce a copper enhanced POY having copper on the surface of the fibers of the copper enhanced POY.

主权利要求
(US9469923) What is claimed is: 1.  A method of producing synthetic textile yarn having copper properties, the method consisting of: a) forming a synthetic fiber by one or more of a spinning process and an extruding process;   b) solidifying the synthetic fiber by a quenching process to form a single partially oriented yarn (POY), the single POY being an undrawn yarn with disoriented polymers;   c) topically coating the surface of the single POY with a solution having a copper additive that does not undergo oxidative degradation during storage; and   d) performing one or more finishing processes selected from a post-extrusion texturing process and/or a post-extrusion spinning/twisting process, wherein the post-extrusion texturing process and/or the post-extrusion spinning/twisting process occurs after the one or more of the spinning process and the extruding process used to form the synthetic fiber, the post-extrusion texturing process, optionally performed during false twisting, being performed by:   (i) heating the single POY during one or more heating cycles of the one or more finishing processes with oven temperatures ranging from approximately 160 degrees Celsius to approximately 600 degrees Celsius; and   (ii) following heating, cooling the single POY during one or more cooling cycles of the one or more finishing processes to a temperature that ranges from approximately 70 degrees Celsius to approximately 150 degrees Celsius to temperature bond the copper additive to the surface of the textile fibers of the single POY and produce a copper enhanced single POY having copper bonded to the surface of the textile fibers of the copper enhanced single POY and having an antistatic property; and the post-extrusion spinning/twisting process being performed by:   (iii) heating the single POY during one or more heating cycles of the one or more finishing processes with oven temperatures ranging from approximately 160 degrees Celsius to approximately 600 degrees Celsius; and   (iv) following heating, cooling the single POY during one or more cooling cycles of the one or more finishing processes to a temperature that ranges from approximately 70 degrees Celsius to approximately 150 degrees Celsius to temperature bond the copper additive to the surface of the textile fibers of the single POY and produce the copper enhanced single POY having copper bonded to the surface of the textile fibers of the copper enhanced single POY and having an antistatic property;   the topically coating occurring after the quenching process and prior to and/or simultaneously with the one or more finishing processes;   optionally drawing the copper coated singly POY having copper properties and disoriented polymer fibers to produce a copper enhanced single POY having copper properties and oriented polymer fibers; and   optionally coating the surface of the single POY with a second topical solution that is a yarn lubricant with a copper containing finishing oil during the post-extrusion texturing process and/or the post-extrusion spinning/twisting process. 2. The method of claim 1, where the drawing is present. 3. The method of claim 1, where the post-extrusion texturing process is performed by a false twist texturing. 4. The method of claim 1, where during a cooling portion of the heating and cooling cycle, cooling the single POY to a temperature that is lower than a glass transition temperature of the single POY. 5. The method of claim 4, where the topically coating is performed simultaneously to the one or more finishing processes and during the heating portion of the heating and cooling cycle a device with rotating rollers carries the single POY. 6. The method of claim 1, where applying the solution to the single POY during the post-extrusion spinning/twisting process is present. 7. The method of claim 1, where topically coating the surface of the single partially oriented yarn with the solution is performed by topically coating the surface of the single POY with a first solution having a copper additive during a post-extrusion texturing process to produce a textured single POY having copper properties; and topically coating the surface of the single POY with a second solution having a copper additive during a post-extrusion spinning/twisting process to produce a textured and twisted single POY having copper properties. 8. The method of claim 1, where copper is exposed and protruding from the surface of the textile fibers of the copper enhanced single POY. 9. The method of claim 1, where the copper additive has copper particles having a size in the range of approximately 1 micron to approximately 2.0 microns. 10. The method of claim 1, where the synthetic fiber is selected from one of polypropylene, polyamide, and polyester. 11. The method of claim 1, where the solution is an aqueous solution. 12. The method of claim 1, where a yarn lubricant containing copper has one or more of natural, organic and synthetic formulations that contain copper. 13. The method of claim 1, where the one or more copper additives are selected from the group consisting of metal particle-containing compounds, metal ion-containing compounds and metal ion-generating compounds. 14. The method of claim 1, where the copper enhanced POY releases copper ions.
