Problems solved by technology

This single polyester coarse detail yarn product is far from meeting people's requirements
[0004] In actual production, mixed fibers can also be combined by selecting two kinds of yarns with different dyeing properties, and then weaving and dyeing, which can obtain a certain color mixing effect, but the process is prolonged and the cost is increased.
In addition, the yarn fineness increases after merging, which is not conducive to the development of light and thin fabrics

Embodiment 1

[0020] 50% by weight of cationic easy-to-dye PET and 50% by weight of ordinary PET are passed through different micropores of the same spinneret during spinning to obtain concentric mixed fiber filaments with the above weight ratio;

[0021] The mixed fiber yarn obtained above is subjected to false twist processing. During the false twist processing, the yarn processing speed is 500m / min, the hot needle temperature HP: 80°C, the draft ratio ID before and after the hot needle: 1.45, and the total draft ratio TD: 1.71, hot plate temperature HT: 200°C. The ordinary polyester filament part of the obtained product is in the form of thick and fine details in the length direction.

[0022] The strength of the thick-detail fancy yarn obtained is 3.73cN / dtex, the elongation is 14.5%, the CV% is 2.02%, and the U% is 1.84%. After processing, the thick and detailed fancy yarns are dyed after knitting, and the cationic dyes are black, and the disperse dyes are yellow, so that three colors...

Embodiment 2

[0024] 70% by weight of cationic easily dyeable PET and 30% by weight of ordinary PET are passed through different micropores of the same spinneret during spinning to obtain the above-mentioned group-type mixed fiber yarn in the weight ratio;

[0025] False-twist the blended yarn obtained above. During the false-twist processing, the yarn processing speed is 350m / min, the hot needle temperature HP: 75°C, the draft ratio ID before and after the hot needle: 1.28, and the total draft ratio TD: 1.60, hot plate temperature HT: 180°C. The ordinary polyester filament part of the obtained product is in the form of thick and fine details in the length direction.

[0026] The strength of the thick-detail fancy yarn obtained was 3.33cN / dtex, the elongation was 20.2%, the CV% was 2.3%, and the U% was 1.74%. After processing, the thick and detailed fancy yarn is dyed after weaving. The cationic dye is blue, and the disperse dye is red. Then three colors of deep purple, red and light red a...

Embodiment 3

[0028] 30% by weight of cationic easily dyeable PET and 70% by weight of ordinary PET are passed through different micropores of the same spinneret during spinning to obtain the concentric mixed fiber filaments with the above weight ratio;

[0029] The mixed fiber yarn obtained above was subjected to incomplete draft false twist processing. During the false twist processing, the total draft ratio was 2.4. The temperature of the hot needle during the false twist processing was 45°C, and the draft ratio before and after the hot needle was 1.6. , the hot plate temperature is 150 °C. The ordinary polyester filament part of the obtained product is in the form of thick and fine details in the length direction.

[0030] The strength of the thick-detail fancy yarn obtained is 2.89cN / dtex, the elongation is 18.7%, the CV% is 2.2%, and the U% is 1.56%. After processing, the thick and detailed fancy yarn is dyed after weaving. The cationic dye is blue, and the disperse dye is red. Then ...

Abstract

The present invention discloses a cationic dyeable commingled twitty processing yarns and its production process. The commingled components are composed of cationic dyeable filament, and ordinary polyester filament which has alternated twits. The production process includes spinning with cationic dyeable polyethylene terephthalate (PET) chip and common PET chip through different micropores of the same spinneret to produce commingled yarn, and false-twisting with incomplete drafting of the commingled yarn to obtain the product. This invention fully utilizes the strong points of different processing method of fancy yarns and produces commingled grey yarn via one-step spinning for false twisting. The product in this invention has a good dyeing result. Three colors can be acquired by incubating common disperse dyes with cationic dyes when dyeing the produced yarns.

Description

Technical field: [0001] The invention relates to a mixed fiber processed yarn and a processing method thereof. Background technique: [0002] At present, there are many kinds of fancy yarns. There are two traditional processing methods. One is to use yarns of the same or different components or yarn counts to form fancy effects through special yarn forming methods such as wrapping, compounding, and core wrapping. The other is to form fancy yarns through special dyeing methods such as segment dyeing, printing and dyeing, etc. These products have their own characteristics and form their own styles. However, these yarns are more versatile, the processing technology is complicated, and the appearance effect has certain limitations. [0003] There are also fancy threads developed using the stretch properties of polyester on the market. The stretching mechanism of polyester is a thin-neck stretching mechanism. When the temperature and stretching force during the stretching proce...
