Design and application of jacquard fabric patterns based on the geomorphologic color features

All kinds of beauty in nature are embodied by color, which is the language of nature and the portrayal of the charm of nature. In nature, landform as one of the basic elements belongs to things in nature, with different causes and types. In a certain area, other physical geographic elements, such as vegetation, hydrology, climate, soil, animals, etc., have direct or indirect influence on the morphology and distribution of the landform. Nowadays, bionic products, bionic decorations and clothing have satisfied human curiosity about nature, promote human beings to continuously explore the unknown nature, bravely reflect the image characteristics of real things, and demonstrate vivid vitality and individual charm in the process of innovation. In recent years, with the large-scale application of multimedia, the color bionics has always been ignored and traditional image processing methods can no longer meet the needs of the market due to their large workload, low efficiency, and artificial subjective color selection. Therefore, it is very necessary to use improved image processing software for color extraction and apply color bionic design to jacquard fabric design. In order to explore the color law of the geomorphic map and apply to the design of jacquard fabric pattern, this paper uses the improved K-means clustering algorithm for the extraction of image color features; at the same time, the composition factors of the geomorphic map are analyzed, and a more typical loess landform is selected as the research object of the same type of landform map, the karst landform and glacial landform are selected as the research objects of different types of landform map. On this basis, RGB value and Lab value are analyzed for the same type of landform map and the color features of different types of landform map; the imitated landform map color features of garment design cases are used to supplement the color matching theory of the landform map, and the color matching rules of the landform map are summarized; finally, the imitated landform color and the jacquard fabric design are combined, and the design schemes of different types of landform color features are studied and formulated. For the first time, the article uses the landforms of nature as color bionic objects, which is a highlight, and this article comprehensively analyzes its color features and explores the methods of landform color bionic design; the colors obtained from K-means clustering are combined with Photoshop image software to make a color chart of the colors of the landform map, so as to analyze the color problems qualitatively and quantitatively in a more accurate manner. Through the above research, it is found that the composition of the landform map is not only the landform itself. The sky, vegetation, animals, etc., are all the factors that constitute the landform map. Because of the existence of these factors, the colors of the landform map can be more vivid and varied; comparing the same type of landform map with different types of landform maps, it can be seen that the RGB value and Lab value can accurately express corresponding colors, making the color value obtained more accurate; through the analysis of the landform map color distribution law, it can be concluded that most landform maps are the matchings between the three colors of black, white, and gray with other color systems. On the premise that the main body is the landform, the color combination with other things is the criterion for color matching. Under normal circumstances, the proportion of warm colors with higher brightness and higher saturation is not large; the landform maps used in this article are stored in a computer, most of which vary with the photographer's shooting angles. How to fill the colors in the landform maps into patterns to achieve color bionics is the key point of this article. From the perspective of the pattern itself, the matching of the same color system is very appropriate, which can create a harmonious picture. With the development of society, different groups of people have different requirements for textiles, so the development of innovative jacquard fabrics is a social development trend. Integrating the design of jacquard fabric pattern and the color bionic design can enrich the whole of the jacquard fabric. The article not only provides a reference for color extraction, but also involves the ingenious integration of color bionic design into the design, and endows traditional jacquard pattern design with higher aesthetic value and aesthetic perception. © 2022 China Silk Association.
