Problems solved by technology
However, due to the long production process of woven jacquard and the complicated installation of looms, it is not suitable for the production of personalized small batches or single image decorative fabrics.
At present, with the improvement of people's living standards, the individual requirements for patterns on clothing and other fabric decoration patterns are getting higher and higher. The existing image weaving and imaging technology needs to use colored yarn due to the complexity of the image design process. There are many types, and the original image cannot be well restored, and it cannot adapt to the current production of personalized small batches or single image fabrics.

Embodiment 1
[0031] Weave a weft-knitted picture-scene decorative wall-hanging fabric with 4 colors and 25 grayscales woven from a portrait photo as a base. Since the weft-knitted fabric is less dense than the vertical density, it is necessary to ensure that the aspect ratio of the image in the fabric is the same as the original If the image is consistent, the original image should be stretched, and the stretching ratio is the vertical density divided by the horizontal density. Then grayscale the color digital image, remove the color information, retain all the grayscale information, and become a grayscale image with 256 levels of grayscale, and use the system clustering method to gradually merge the color with the smallest grayscale color difference on the grayscale image, so that the The grayscale of the grayscale image is compressed to 25 levels, and finally compressed into 4 kinds of grayscale color coils according to the jitter compression method, such as image 3 Shown is the partial...

The invention relates to a processing method for fewer-color multi-layer weft-knitting gray-level scene knitted fabric. Gray level conversion, compression and shaking compression are conducted on an image, 3-8 kinds of primary color levels are used for expressing a colorful image, meanwhile washing preshrinking shaping is conducted aiming at the characteristics of figured texture weave to obtain a final finished product. The processing method has the advantages of being capable of utilizing fewer colors to show patterns in various pattern shapes, suitable for production of personal small-amount or single-width scene decoration knitted fabric and good in application value.
Description
technical field [0001] The invention relates to a processing method of a weft-knitted gray scale image-knitted fabric with few colors and multiple levels. Background technique [0002] At present, the image-like fabrics all adopt the woven jacquard method, and realize the multi-level realistic image effect on the fabric surface with the cooperation of warp yarns or weft yarns of different colors exposed on the fabric surface and the structure of the fabric. However, due to the long production process of woven jacquard and the complicated installation of looms, it is not suitable for the production of personalized small batches or single image decorative fabrics. At present, with the improvement of people's living standards, the individual requirements for patterns on clothing and other fabric decoration patterns are getting higher and higher. The existing image weaving and imaging technology needs to use colored yarn due to the complexity of the image design process. There ...
