Embodiment 1

[0160] Example 1: In the melt spinning process with the method of the present invention by using a correction system for correcting the liquid-masterbatch composition

[0161] The polymer support is polyester with a solid-masterbatch dispersed therein.

[0162] Spinning of gray polyester yarn was carried out by dosing solid masterbatch. The solid masterbatch was developed for mass coloring of the threads used to make the fabrics that trim car seats. The automotive industry has very high color requirements and cannot tolerate batch-to-batch deviations.

[0163] A solid-masterbatch (Solid-M) was prepared with the following pigments: Pigment Black 7, Pigment Blue 29, Pigment Green 7, Pigment White 6, Pigment Red 202. Solid-M contained a total of 16.4% by weight of pigment. To obtain the final color, the dosage of this solid-M is 2.5% based on the total weight of polyester. This means that the amount of colorant contributed "on the fiber" will be 0.41% (16.4x2.5 / 100).

Embodiment 2

[0185] Example 2: Correction system by using correction liquid-masterbatch composition in melt spinning process

[0186] The polymer support is a polyester having dispersed therein a solid concentrate and a liquid concentrate. Solid-M was prepared as in Example 1. Liquid-M was prepared with a mixture of inert oil and 38% wt. of Pigment Green (P.G. 7).

[0187] Spinning polyester yarn was performed by dosing 2.5% wt. solid concentrate and 0.079% wt. liquid concentrate. The extruded yarn is air-textured. The fabric is then knitted from this yarn. This fabric was placed in the sample holder of a Datacolor 650 spectrophotometer. Take the average reading in the spectrophotometer to determine the coordinates L, a * and b * . The results for Illuminant D65 10 degrees are included in Table 12 below. coordinate a * and b * These readings are not within tolerance of the desired target hue color coordinates, see the target hue color row.

Abstract

The present invention provides a method for correcting the color hue of synthetic yarns and / or filaments that have been colored in conventional melt spinning processes, which allows the deviation of the tolerance of the color hue to be corrected by the manufacturer itself. The method includes storing color coordinates of a target hue; measuring the color coordinates of the colored yarns and filaments to be corrected; comparing the data to provide a deviation beyond the tolerance; preparing a correction-liquid-masterbatch composition; converting the deviation beyond the tolerance to correct the dose of the liquid-masterbatch composition; and adding such doses to the molten mass of the synthetic yarns and filaments. The invention also relates to a system suitable for performing a color hue correction and / or correction method.

Description

technical field [0001] The present invention belongs to the field of colored synthetic fiber production, mainly for the textile industry, and relates to the correction of the color hue of such colored synthetic yarns and fibers in conventional melt spinning procedures. [0002] In particular, the present invention relates to a method for correcting the color hue of colored synthetic yarns and filaments during extrusion in a melt spinning process, and for implementing the method to correct beyond what is normally done in colored synthetic yarns and filaments. A system for tolerances of color hue deviations that occur during the production of filaments. [0003] The present invention also relates to the use of a liquid-masterbatch composition for implementing a color hue correction by the manufacturer himself during extrusion in a melt-spinning procedure in a method for correcting the color hue. Background technique [0004] The polymer support, or primary polymer, is the med...
