Field of the Invention The present invention relates to a polyester fiber yarn composed of continuous fibers, which forms a carpet which is highly uniform in appearance when used as a tuft of a carpet and is less likely to be charged, and a method for producing the same. The carpet fiber of the present invention is

に対して優位にあることの方が大きいと考えられる。2. Description of the Related Art With the development of synthetic fibers, the mainstay of carpet fibers has shifted from wool to synthetic fibers. It is considered that the cause of this tendency is that synthetic fibers are suitable for carpets in terms of performance, but rather it is more advantageous in terms of cost over wool.

維が外れて出て来る問題がある。Synthetic fiber carpet fiber forms have long been used in staple form, similar to wool. This is thought to be due to the advantage that there is little difference from wool in terms of product form, but it is not always rational from the viewpoint of manufacturing synthetic fibers. Synthetic fibers are originally produced as continuous fibers, but staples are naturally disadvantageous in terms of cost because they require extra steps such as cutting and spinning. Further, in the case of a carpet made of spun yarn, since the single fiber is cut short, there is a problem that a large amount of fiber comes off due to friction.

ことがわかった。この欠点は特にタフテッドカーペット

沢の異なる部分や色相の異なる部分が現れる。When making carpet fibers from continuous synthetic fibers, it is essential to crimp the fibers in order to make them bulky and to improve cushioning properties and resilience.
Conventionally, the development of a technique for providing crimps to synthetic continuous fibers has been actively promoted, and several types of high-speed techniques capable of being directly connected to the spinning and drawing process to be processed have been developed. Since these techniques have high speed and high efficiency and thus have a low production cost, it has been found that there are frequent problems that are not found in spun yarn carpets. This defect is often seen especially in tufted carpets, and streaks of different gloss and different hues appear parallel to the running direction of the tufted needles.

い。Mottling similar to this is not known for crimped yarns that have been widely used in the past. The reason for this is considered to be that the conventional crimped yarns are relatively thin yarns and are mostly false twisted yarns, whereas crimping of carpet fibers is based on a stuffing type or a type. Since it is extremely difficult to perform false twisting on a thick yarn such as carpet fiber, it is unlikely to use the false twisted yarn for carpet in the future.

い問題がある。A drawback of conventional carpets is that pedestrians are more charged than other floor materials. In order to solve this problem, the conductive resin is processed into the fiber or the conductive fiber is mixed. Although these methods have shown considerable effectiveness, they have the problem of increasing the cost of the carpet, and the antistatic effect is not permanent.

The frequency of appearance of portions having different hues is not significantly reduced, which is not preferable.

るものと思われる。In the present invention, when the contents of the carboxyl end groups are different, it is not clear why the defects appearing in stripes are reduced. One of the possible reasons is that there is a difference in the easiness of attachment of something having an electric charge. The chargeability of the carpet fiber of the present invention does not show a particularly noticeable difference from conventional products immediately after production,
It is recognized that during actual use, it becomes very difficult to be charged in a relatively short period of time. It is presumed that this is because particles having a charge are attracted from the outside to form a conductive layer on the fiber surface. A similar phenomenon occurs during stuffing crimp due to airflow, and aerosol particles of oil or water concentrate on some components and form short-period unevenness, making long-period unevenness inconspicuous. It is presumed that Since ionic carboxyl end groups are unstable inside the polyester and easily collect on the surface, it is considered that this phenomenon occurs due to the presence of a stable charge on the surface of polyester with a high content of carboxyl end groups. .

小の差は、好ましくは２〜１５％である。When the difference between the maximum and the minimum content of the carboxyl terminal group is 0.5% or less, streak unevenness is not significantly reduced, which is not preferable. On the other hand, when the content is 25% or more, the light resistance of the component having the largest content of the carboxyl terminal group is poor, and thus the appearance of the carpet changes rapidly with time, which is not preferable. The difference between the maximum content and the minimum content of the carboxyl end groups is preferably 2 to 15%.

Usually, stuffing or crimping is applied. The method of the present invention is effective for providing a stuffing crimp. The stuffing crimping method includes a method using an air flow and a method using a nip roller, but the method of the present invention is effective in any case. The crimping is preferably performed continuously with the stretching step. It is most preferable to apply the crimps continuously after the spinning and drawing steps because the cost is low.

Fibers, or those having different melting points of 2 ° C. or more. Here, as the intrinsic viscosity of the polyester fiber, a value measured at 30 ° C. using an equal mixture of tetrachloroethane and phenol or orthochlorophenol as a solvent is used. It is noted that the difference in the properties of these polyesters may enhance the effect of the difference in the content of carboxyl end groups. It is preferable that the pigment concentration of the component having a high carboxyl terminal group content is high, the blending ratio of the recycled resin is high, the intrinsic viscosity is low, or the melting point is low.

A melt is made, the melt is melt-spun, and further stretched in the melt-spinning process, and the maximum content of carboxyl end groups relative to all the end groups of the continuous fiber polyester obtained at that time is obtained. The fibers are made to have a difference from the minimum of 0.5 to 25%, and then crimped by being press-fitted into the stuffing box by heating gas.

面に導電性の層を形成するためと推定される。The streak-like unevenness, which appears relatively frequently in the carpet fiber made of continuous fibers, is presumed to be due to the fact that this fiber has a fairly long-period nonuniformity. In the present invention, when there is a difference in the content ratio of the carboxyl end group, the reason why streaky unevenness is reduced is not clear. One of the possible reasons is that there is a difference in the easiness of attachment of something having a charge. The chargeability of the carpet fiber of the present invention does not show a particularly noticeable difference from conventional products immediately after production, but during actual use,

It is presumed that it will be inconspicuous. Since ionic carboxyl end groups are unstable inside the polyester and tend to collect on the surface, it is considered that this phenomenon occurs due to the presence of a stable charge on the surface of polyester with a high content of carboxyl end groups. .
