Problems solved by technology

With the increase of dyeing demand, more waste water will be produced during the dyeing process, and the impact on the environment will be greater. Compared with yarn dyeing and gray cloth dyeing, fiber dyeing has higher dyeing rate, less waste water and less impact on the environment. However, fiber dyeing has the same dyeing process for each fiber, so the color on the surface of each fiber is the same, and the color is relatively dull.

Embodiment 1

[0043] A kind of juxtaposed composite bright short fiber, such as figure 1 As shown, it includes a first color part with a semicircular cross-section and a second color part with a semicircular cross-section, the cross-sectional radius of the first color part and the cross-sectional radius of the second color part are equal and combined Form a circle. The color of the first color part is a single solid color, the color of the second color part is a single solid color, the color of the first color part is different from the color of the second color part, and the color of the first color part is smaller than the color of the second color part deep.

[0044] The above-mentioned juxtaposed colorful short fibers are prepared by the following method:

[0045] (1) Weigh dimethyl polysiloxane, sucrose benzoate, and 2-ethylhexyl phosphate in a mixer, heat up to 140°C, stir for 20 minutes, mix evenly, and cool to obtain Modifier;

[0046] (2) The polyamide fibers and the modifying ...

Embodiment 2-5

[0052] The difference between Examples 2-5 and Example 1 is that the ratio of raw materials for preparing the side-by-side composite bright short fibers is different, as shown in Table 1 and Table 2.

Embodiment 6

[0054] The difference between Example 6 and Example 4 is that the process conditions and some raw materials for preparing side-by-side composite dazzling short fibers are different; (1) weigh the dimethyl polysiloxane, sucrose benzoate, phosphoric acid- 2-Ethylhexyl ester is placed in a mixer, heated to 145°C, stirred for 20 minutes, mixed evenly, cooled to obtain a modifier;

[0055] (2) The polyurethane fiber and the modifying agent in the step (1) that take weight formula are placed in the mixer, stirred for 15 minutes, and mixed uniformly, thereby obtaining the mixture;

[0056] (3) The polyester fiber is passed through the metering pump and then enters the composite spinning box; at the same time, the mixture in the step (2) is passed through the metering pump and then enters the composite spinning box, and then passes through the parallel composite spinning assembly, at a temperature of 260 ° C. Spinning under the same conditions, and after cooling, drawing, deep drawing...

Abstract

The invention relates to a side-by-side composite colorful short fiber and a preparation method thereof and belongs to the technical field of fiber preparation. The side-by-side composite colorful short fiber solves the technical problem that the surface color of the fiber is single and rigid. The side-by-side composite colorful short fiber comprises several color parts arranged side by side alongthe length direction. The color part has a single color and the colors of the color parts are different. The color part comprises a first color part and a second color part. The first color part comprises first raw material fibers and a first dye. The second color part comprises second raw material fibers, a second dye and a modifier. The modifier comprises dimethicone, sucrose benzoate and 2-diethylhexyl phosphate. Through use of the modifier in the second color part, the first color part and the second color part can respectively dye at different dyeing temperatures so that the side-by-sidecomposite colorful short fiber has two surface colors and the applicability of the side-by-side composite colorful short fiber is improved.

Description

technical field [0001] The invention relates to the technical field of fiber preparation, more specifically, it relates to a side-by-side composite colorful short fiber and a preparation method thereof. Background technique [0002] The coloring of textiles is the prerequisite for the normal use of textiles. At present, most of the ways to give colors to textiles are dyeing. In the prior art, textile dyeing is usually divided into the following processes: one is fiber dyeing; the other is yarn dyeing; the third is greige dyeing. Fiber dyeing is widely used in color spinning enterprises. Fiber dyeing is used to obtain special color expressions through color matching; yarn dyeing is mainly used in yarn-dyed weaving, and colored yarns are obtained after the spun yarns are dyed, and then weaved; Gray cloth dyeing is mostly used for finished products, which can help textiles to obtain a consistent color across the entire width. With the increase of dyeing demand, more waste wat...
