Abstract

SE PRESENTAN HILOS PLANOS CONTINUOS FORMADOS DE VARIOS FILAMENTOS DE NYLON PARA ROPA DE VESTIR QUE PUEDEN SUFRIR APLICACIONES CRITICAS DE TINTES ASI COMO UN PROCESO PARA FABRICAR TALES HILOS. EL PROCESO PARA FABRICAR LOS HILOS INCLUYE EL HILADO DE UN POLIMERO DE NYLON CON UNA VISCOSIDAD RELATIVA ENTRE 35 Y 80 Y SU ESTABILIZACION PARA FABRICAR UN HILO DE ALIMENTACION. LA VELOCIDAD DE EXTRACCION EN EL HILADO ES SUFICIENTEMENTE ALTA COMO PARA SUMINISTRAR HILOS DE ALIMENTACION ALTAMENTE UNIFORMES. EN EL PROCESO, EL HILO DE ALIMENTACION ES ABSORBIDO Y SUBSECUENTEMENTE RELAJADO, PREFERIBLEMENTE EN LA FORMA DE UNA URDIMBRE DE HILOS, DE FORMA QUE LOS HILOS ABSORBIDOS RESULTANTES TIENEN PROPIEDADES ADECUADAS PARA SU USO COMO HILOS PLANOS Y PRESENTAN UNA EXCELENTE UNIFORMIDAD DE COLOR CON TINTES ACIDOS DE MOLECULA LARGA.CONTINUOUS FLAT THREADS FORMED OF SEVERAL NYLON FILAMENTS FOR CLOTHING ARE PRESENT, WHICH MAY SUFFER CRITICAL APPLICATIONS OF DYES AS WELL AS A PROCESS TO MANUFACTURE SUCH THREADS. THE PROCESS TO MANUFACTURE THREADS INCLUDES THE SPINNING OF A NYLON POLYMER WITH A RELATIVE VISCOSITY BETWEEN 35 AND 80 AND ITS STABILIZATION TO MANUFACTURE A FEEDING THREAD. THE EXTRACTION SPEED IN THE YARN IS ENOUGH HIGH TO SUPPLY HIGHLY UNIFORM FEED WIRE. IN THE PROCESS, THE FEEDING THREAD IS ABSORBED AND SUBSEQUENTLY RELAXED, PREFERABLY IN THE FORM OF A THREAD WRAP, SO THAT THE RESULTING ABSORBED THREADS HAVE SUITABLE PROPERTIES FOR FLAT THREADS AND PRESENT AN EXCELLENT PROPERTY OF AN EXCELLENT THREAD LONG MOLECULA.
