Problems solved by technology

[0025] Even for polyethylene terephthalate, one of the representative raw materials of polyester threads, pigments are foreign substances, and the higher the rate of foreign substances mixed, the polyester threads formed of polyethylene terephthalate The more the original physical properties are destroyed, it is difficult to make thinner wires, even if it can be made, it will leave the problem of insufficient strength

Embodiment Construction

[0037] Here, in order to describe the present invention in more detail, an example is given.

[0038] Use a screw melt extruder to melt polyethylene terephthalate at a temperature of 200°C to 400°C, and use a metering screw feeder to lightly pulverize the carbon black to 10 to 100nm by 2.3 Weight % is added, and one side is blown with cooling air at 25° C. to 28° C. to obtain an unstretched thread from a position 4 cm below the metal spout at 400 g / min. At this time, it was found that the uniform dispersion in the polyethylene terephthalate in which the carbon black was melted was very fast.

[0039] Subsequently, the obtained unstretched thread was elongated to 2.0 to 2.5 times by 2-stage warm water drawing method at 50°C / 90°C, and a black dyed polyester thread with a fineness of 1.5 denier was used to obtain tow.

[0040] Cut the tow equally according to the length of 3.8mm to obtain black polyester fiber, put it on a carding machine and carry out slivering, and obtain the ...

Abstract

A conventional polyester fiber dyeing method has the problems of whitening the uniformity of colors, dyeing property, firmness and the like caused by natural properties and physical properties of raw material resin, so that the invention provides a raw material coloring method which is simple and easy, utilizes simple and convenient equipment, can greatly save water and can greatly relieve a load to an environment by considering the color emissivity, the manufacturing cost, high-price and large-scale initial investment and the relieving of the environmental load. An explosion crushing or micro-crushing machine is used for crushing a into crushed pigments or coloring agents with the sizes of 5-100nm; and compared with the prior art, the rapid and equal dispersion rate is realized by greatly reducing the mixing rate, and a polyester line can be obtained without the need of providing special conditions for melting polyester resin. By using he method disclosed by the invention, not only industrial water can be saved, but also the load to the environment can be greatly reduced by industrial water drainage.

Description

technical field [0001] The present invention relates to fibers having excellent usefulness such as high strength, good texture, and dimensional stability using so-called polyester threads and polyester fibers made of polyester resin (polyethylene terephthalate resin) It is a simple technology that can make the inevitable dyeing process easier than ever before for fabrics and textile products. In addition, the present invention also relates to a technology that responds to the requirements of the environmental protection era by making the very useful polyester fiber that is difficult to dye in the past stronger without increasing costs and equipment expenses, and with very little waste and water consumption. Background technique [0002] In the past, dyes and pigments were mixed into polyester resin at the raw material stage, and dyed and then spun into yarns. (Patent Document 1) [0003] In addition, the technique of dyeing with disperse dyes under high temperature and hig...
