Conventionally, as a stretching false twisting processing method for polyester, 3.00
A method has been adopted in which polyester yarn spun at around 0 m/min is subjected to stretching and false twisting. The false twisted yarn thus obtained has mechanical properties sufficient for practical use.

However, when dyeing, what is normal? Since it is necessary to perform the process at a high temperature and high pressure of around 130° C. as in the case of Lyester fiber, a special force device is required and a large amount of energy is consumed.

In addition, there are also problems such as restrictions on the use of fibers such as wool and acrylic fibers, whose physical properties are significantly deteriorated when dyed at high temperature and high pressure.

Several attempts have been made to improve the dyeability of polyester fibers, especially to make them dyeable under normal pressure.For example, a method of using a carrier during dyeing is known, but it requires a special carrier, and It has drawbacks such as difficulty in processing. In addition, polyethylene terephthalate with improved dyeability is known by copolymerizing metal sulfonate group-containing compounds and polyether, but although these modified polyesters improve dyeability, they do not polymerize or
There are drawbacks such as difficulty in spinning, deterioration of the original excellent properties of polyethylene terephthalate, and poor color fastness. In the end, the chemical modification of the polymer to make it easier to dye as described above inevitably changes the original properties of polyethylene terephthalate because a third component that can serve as a dyeing seat is mixed into the polymer. It can be said.

The present inventors have overcome the shortcomings of such conventional methods and have developed a polyester processed yarn that has good dyeability, can be particularly pressure-dyed, has excellent color fastness, and also has the original desirable properties. As a result of research into a method for manufacturing efficiently, ie, energy-saving, and with good operability, the present invention was completed.

"Undrawn polyester fiber" refers to a fiber that is substantially made of polyethylene terephthalate and has not been subjected to a mechanical stretching process after being spun and wound. This polyester can be obtained by known polymerization methods and may contain additives normally used in polyesters, such as matting agents, stabilizers, antistatic agents, etc. In addition, there are no particular restrictions on the degree of polymerization as long as it is within the range for normal fiber formation, and copolymerization with small amounts of other components is of course possible within a range that does not violate the purpose of the present invention. be.

Furthermore, the term "stretch false twisting" herein generally refers to the so-called in-draw false twisting process in which false twisting is performed at the same time as stretching (that is, false twisting process at a draw ratio>1.0).

In the present invention, the undrawn polyester yarn supplied to the drawing and false twisting process is spun at a spinning speed of 4,000 m/min or more. If the speed is less than 4,000 m/min, the crystalline regions of the polyester are insufficiently developed, resulting in the microstructure of the fibers being thermally unstable and melting and fusion breaking during subsequent heat treatment.

This heat treatment is performed substantially without stretching.

The heat treatment is preferably carried out while the running polyester yarn is brought into contact with a heater at a predetermined temperature, and the features of the present invention are best exhibited by this method. The dyeability of polyester fibers is improved by heat-treating the polyester yarn at 190° C. or higher without subjecting it to substantial stretching, cooling it, and then subjecting it to stretching and false twisting. That is, the affinity (4) for dyes is improved, and practical dyeing can be performed at a lower temperature without the need for dyeing at 130° C. under high temperature and high pressure. In particular, by selecting the heat treatment temperature and time so that the yarn temperature is 220°C or higher, the same dyeability as dyeing at 130°C at normal pressure can be obtained. In this case, if the yarn temperature exceeds 240°C, the operability of threading will deteriorate, so a temperature of 220 to 240°C is preferable.

Furthermore, it is important that the heat treatment is performed with twisting. When the yarn is twisted, even if the heat treatment is performed at high speed, the filaments constituting the yarn will not get caught or some of the filaments will lift up, which will deteriorate the operability. In addition, it is possible to perform heat treatment while in contact with the heater, improving heat propagation efficiency, and as a result, the contact time with the heater can be shortened to 0.2 seconds, allowing the length of the heater to be shortened and heat treatment Since speed can be improved, energy savings and high productivity can be achieved. The forerunner may be heat-treated by twisting the yarn, or may be heat-treated while being twisted, but the latter is more efficient and preferable. After heat-treating in this way, the yarn is After cooling to below the heat treatment temperature, preferably below 90°C, stretching and heating processing is performed.

When passing through the heat treatment heater 9, the yarn 7 has a false twister 1.
The twist that can be propagated from 4 is given. After being heated in the heat treatment heater 9 in a twisted state, the yarn 7 is cooled by the indoor atmosphere and guided into the false twisting heater 13 via the twisting guide 11. Without this cooling and twisting guide, stretching tension would be exerted within the heat treatment heater. It is heated in the false twisting heater 13 to a temperature above the glass transition point, and stretching begins. The point at which the stretching begins is the stretching point 12. After passing through the false twisting heater 13, the yarn is cooled again by the indoor atmosphere, untwisted immediately after passing through the false twister 14, and wound through a delivery roller 15 to form a yarn package 17 of drawn false twisted yarn. Here, 16 is a winding friction roller (R3).

Example 1 3 in a 2/1 mixed solvent of phenol/tetrochloroethane
Polyethylene terephthalate with an intrinsic viscosity [η] of 0.64 measured at 5°C was spun at a spinning temperature of 298 (7)°C from a spinneret with a pore diameter of 0.35%φ and 32 holes, parallel to the running direction of the yarn. The spun filament was cooled and solidified by a flow of air at 25 DEG C., then a finishing agent was applied and it was wound up at a speed of 3,000 to 6,000 lmin. The thus obtained polyester 150d/32 filament having the properties shown in Table 1 was processed using the apparatus having the specifications shown in Table 2 under the processing conditions shown in Table 3. The results are shown in Table 4.

From Table 4, it can be seen that polyester textured yarn with good dyeability cannot be obtained by the conventional stretch false twisting method, but textured yarn with improved dyeability can be obtained by employing the method of the present invention. However, it can be seen that even if the same processing process as in the present invention is adopted, unless the feeding system is one that spins at a rate of 4,000 fi/min or more, the threading is difficult to operate and the operability is poor.

The following points are clear from the manufacturing numbers 4 and 8-2.8-3.8-4 in Table 8 in the margins below. In other words, in the present invention, if the fiber yarn is brought into contact with the surface of a heat treatment heater at 200°C or higher with a twist of 3% or more of the number of twists in the yarn, the yarn can be easily threaded. Yarns with better handling properties and improved dyeability can be obtained by short heat treatment. It can be seen that when the heat treatment heater temperature is less than 200°C, the obtained processed yarn is not easily dyed (8-1).

As explained above, according to the method for producing easily dyeable polyester processed yarn of the present invention, a processed polyester yarn with improved dyeability that cannot be obtained by conventional drawing and false twisting can be produced using a simple device and a simple yarn. It can be seen that the hanging can be manufactured with ease of operation.
