Problems solved by technology

This "requirement" of sample preparation limits the application of double constant Kubelka-Munk theory in actual production
On the other hand, there is a change in the refractive index at the junction of the mixed sample and air, and this discontinuous change causes multiple internal reflections of light inside the mixed sample

Embodiment

[0045] Embodiment comprises the following steps:

[0046] 1) Select a colored fiber as a reference standard, and prepare a calibration sample with a ratio of 100%;

[0047] Embodiment Select the colored fiber S with the highest brightness as the calibration colored fiber for preparing the calibration sample, and prepare a calibration sample with a ratio of 100% according to the shape of the target sample (sliver, fabric or yarn, etc.).

[0048] 2) For each colored fiber, prepare a single-component colored fiber sample with a ratio of 100%, and then mix each colored fiber with the calibrated colored fiber in the ratio of c:(1-c) to prepare A mixed sample, as a solution sample for the scattering coefficient and absorption coefficient of each colored fiber;

[0049] During specific implementation, it is recommended to take c as 40%.

[0050] In the embodiment, if the four colored fibers A, B, C and D do not contain the calibrated colored fiber S of 1), it is necessary to prepar...

Abstract

The invention relates to a colored fiber mixed color matching method based on the double-constant Kubelka-Munk theory and belongs to the technical field of dyed spinning. The method includes the steps that a colored fiber scattering coefficient and absorption coefficient solving sample is prepared; sample spectral reflectance is measured, and visible spectral data is intercepted; multiple internal reflection correction is conducted on actually measured spectral reflectance data; a colored fiber scattering coefficient and an absorption coefficient are solved; target spectral reflectance is measured, and visible spectral data is intercepted; ratio prediction of colored fibers matched with target colors is conducted. By means of the method, an ideal ratio prediction result can be obtained on the premise hat the number of samples is reduced, implementation is convenient, and the method is high in practicality in the field of dyed-spun colored fiber mixed color matching.

Description

technical field [0001] The invention belongs to the technical field of color spinning, and in particular relates to a method for mixing and matching colored fibers based on the double-constant Kubelka-Munk theory. Background technique [0002] Colored yarn is a yarn with special color effects that is produced by dyeing fibers into colored fibers first, and then fully mixing two or more colored fibers of different colors to spin them. Compared with the traditional production process of spinning first and then dyeing, or weaving the yarn into cloth and then dyeing, the color spinning process has significant advantages in terms of energy saving, emission reduction, and environmental protection. On the other hand, because it is spun from colored fibers of different colors, the color-spun yarn can present multiple colors on the same sand thread. The texture is favored by consumers. At present, the color spinning industry has become a sunrise industry in the textile industry. ...
