Embodiment

[0065] exist Figure 1 to Figure 15Indicates an example. In these figures, 2 is a yarn image generating device, and 4 is a fiber data storage unit, which stores parameters related to raw material fibers. In the fiber data storage unit 4, the ratio of the raw material fibers used for the melange yarn and their color data, as well as the thickness, length, unevenness of the thickness, whether the raw material fibers are sufficiently disassembled and mixed uniformly or unevenly mixed are stored. The unevenness of fiber distribution, etc. In this specification, color data is stored as (R, G, B), for example, but may also be stored as hue H, brightness V, saturation C, and the like. Furthermore, in this specification, the notation α is used for transparency, the higher α is, the more transparently the image of the underlying layer is visible.

[0066] In the present invention, transparency α is used in order to express the vertical overlap of fibers of different color data. For...

Abstract

For formation of a yarn image of melange yarn, layers of image having multiple types of fibers of differentiated colors arranged randomly are piled one upon another into a stack of multiple layers. The degree of transparency is determined from the brightness of each of the fibers, and an image synthesis is carried out with respect to the image layers piled one upon another, thereby forming a yarn image of melange yarn. Thus, a yarn image can be formed without any test production of melange yarn. Further, there can be realized a real expression of texture sensation owing to vertical piling of differentiated colors.

Description

technical field [0001] The invention relates to the generation of yarn images of melange yarns. Background technique [0002] Melange yarn is a yarn obtained by mixing various fibers of different colors. As for what color and texture of melange yarn can be obtained by mixing what color fiber in what proportion, at the current stage, it is still a matter of trial and error that can only be judged by actually mixing fibers to make melange yarn. However, before adopting a kind of melange yarn, it is necessary to trial-produce the melange yarn many times. [0003] In addition, the yarn image of the melange yarn is necessary for the simulation of a fiber product using the planned melange yarn in addition to the design and trial production of the melange yarn. For example, the simulation of knitted products using melange yarn is not to express the knitting data, but to express the color tone and coil shape of the melange yarn, and the yarn image of the melange yarn is required. ...
