Problems solved by technology

[0008] The uniform blending method of spot-color fibers solves the problems of competing dyeing and staining that may exist in the dyeing process of blended and mixed-color products (mixing of different fibers and different colors) to a certain extent, but this method needs to be prepared according to different target colors. Multi-color spot color fibers are not conducive to reducing the inventory of dyes in enterprises
A well-known mixed-color yarn production factory has more than 3,000 kinds of colored fibers in stock, resulting in a large backlog of funds

Embodiment 1

[0047] Embodiment 1 (uniform plain woolen fabric)

[0048] 1) Select the primary color dyes: Lannasol-red 6G, Lannasol-yellow 4G, Lannasol-blue 2R, Lannasol-black CE four primary color dyes (purchased from Shanghai Huntsman Co., Ltd.), dyeing concentration Both are 3%, so as to obtain a color with higher saturation and a higher utilization rate of the dye.

[0049] 2) Preparation of primary color fiber: put the natural color wool top in the top dyeing machine, the bath ratio is 1:20, when the temperature of the dyeing bath is raised to 40°C, add 5% of the fiber quality of sodium sulfate, 1.5%-1.7% of the fiber quality Formic acid with a concentration of 85% and Abaiger relative to the dyeing bath capacity of 1g / L, after 5min, add the above-mentioned four primary color dyes and dye for 5min, heat to 98°C at a heating rate of 2°C / min, and fix the color 50min; when the temperature is lowered to 85°C, add soda ash and keep the temperature constant for 20min; after cooling down to...

Embodiment 2

[0054] Embodiment 2 (uniform plain cotton fabric)

[0055] 1) Select primary color dyes: preferably Norwich Red C-4B, Norwich Yellow C-5G, Norwich Turquoise Blue GN, Norwich Black B four primary color dyes (purchased from Shanghai Huntsman Co., Ltd.), dyeing The concentration is 3%, thus obtaining a color with higher saturation and a higher utilization rate of the dye.

[0056] 2) Preparation of primary color fibers: Dyeing in a bulk fiber dyeing machine with a bath ratio of 1:20. Use the constant temperature (60°C) dyeing method, add the above four dyes at 60°C, add 60g / l of salt after dyeing for 15min, add soda ash 18g / l after dyeing for 15min, fix the color for 30min, cool down after dyeing, take out Fiber, wash, tumble dry. Four-color primary color fibers are thus obtained. The colorimetric indexes of the obtained primary color fibers are listed in Table 2.

[0057] 3) Make uniform plain color fabrics: select magenta, yellow, blue, black and natural color five primary ...

Embodiment 3

[0061] Embodiment 3 (uniform plain colored polyester fabric)

[0062] 1) Choose magenta, yellow, cyan, black and natural polyester staple fibers (1.33dtex×38mm) provided by Jiangsu Xiake Environmental Color Spinning Co., Ltd., and their chromaticity indicators are listed in Table 3.

[0063] 2) Make uniform plain fabric: select five primary color fibers of magenta, yellow, cyan, black and natural color, and evenly mix them according to the mixing ratio of magenta:cyan=4:1. In the pre-spinning production, optimize the arrangement of fiber packs during fiber grabbing, increase the number of drawing frames to 3-5 times to achieve uniform mixing of multi-color fibers, and adopt conventional post-spinning and weaving processes to make rovings and take rings The spindle spinning machine spins 18.22tex × 2 polyester yarns, and the weaving dyeing and finishing process of Example 2 prepares uniform plain polyester fabric #5, such as Figure 5 As shown, its chromaticity value Lab is sh...

Abstract

A method of preparing a homogeneous plain-color fabric based on color matching of primary color fiber is disclosed. The method adopts yellow, pinkish red, green, black and white fibers as raw materials, and includes steps of determining a blending ratio of four primary-color fibers and the white fiber according to a target color through computerized color matching, and homogenizing by adoption of a blending technology in conventional spinning methods to obtain the homogeneous plain-color fabric. Appearance of the plain-color fabric is similar to that of slub dyeing or piece dyeing plain-color fabrics, but the plain-color fabric shows multi-color fiber in the micro scale. The plain-color fabric is obtained by blending and weaving yellow, pinkish red, green, black and white fibers of the same kind, or different kinds. The method can reduce reserves of dye varieties and color fiber varieties, thus facilitating management, and can effectively overcome the problem that a plurality of kinds of fiber blended fabrics which are conflict in dyeing conditions are difficult in piece dyeing.

Description

technical field [0001] The present invention relates to the textile field. In particular, the present invention relates to methods for preparing uniform plain fabrics. Background technique [0002] The primary color mixing theory has been widely used in color printing. With white paper as the base, four color inks of yellow, magenta, cyan and black are selected, and the ink dots are "paralleled" through different dot area ratios of each color ink and different screening methods. ” or “overprint” to get a variety of mixed colors, which can express a larger color space. [0003] At present, the rapid development of inkjet printing technology adopts the method of primary color printing. However, the primary color dyes used in inkjet printing are not primary colors in the sense of chromatics, but an ink system of 8 colors is used to achieve a relatively complete color spectrum. Moreover, the ink systems used by various inkjet printing equipment suppliers are also different, a...
