ポリエステルフィラメント糸に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a polyester filament yarn for carpet face yarn made from polyethylene terephthalate resin recovered from molded articles.

である。The present invention uses polyethylene terephthalate resin recovered from molded products, which has relatively low light resistance and poor white discoloration and color properties, as the main raw material. It is a polyester filament yarn.

途に使用することができる。The polyester filament yarn of the present invention can be crimped with excellent performance, and because it is made from inexpensive polyethylene terephthalate resin recovered from molded products, it is highly cost-competitive, such as tufted carpets, etc. It can be used in a variety of applications, including as the face yarn of carpets.

れている。(b) Conventional technology The polyester filament for carpets, especially the bulky continuous yarn called BCF, has a higher specific gravity than other types of resins such as nylon and polypropylene used as BCF. Therefore, it has the disadvantage that the covering power of the carpet face yarn is rather small, and in order to deal with this, it has traditionally been thought that it is better to increase the amount of face yarn.In order to achieve this goal, There is a need for low prices for polyester filament yarns.
このような状況から従来のポリエステルのＢＣＦでは、

するなめ、染色むらを生じ易い問題がある。Due to this situation, in the conventional polyester BCF,
Yarn costs have been reduced by methods such as directly linking the spinning process and the crimping process. On the other hand, however, as a result of such shortening and speeding up of the process, it has become difficult to provide a heat treatment time long enough to stabilize the crimped form and the crystal structure of the fiber in the crimping process. Crystallization of fibers is possible even after processing into Carpela I.
Since the fibers are processed into carpets with unstable fiber morphology and crystal structure, there is a problem that uneven dyeing tends to occur.
従来からこれを回避するには、極めて均一性の高い原料
を用いる必要があり、製造工程に対する高い管理水準が
要求されると考えられている。Conventionally, it has been thought that in order to avoid this, it is necessary to use raw materials with extremely high uniformity, and a high level of control over the manufacturing process is required.
コストの低減には、製造工程の合理化のほかに省力化や
原材料の価格の低減などが考えられる。In addition to rationalizing the manufacturing process, possible ways to reduce costs include labor saving and lowering the price of raw materials.

が現状である。However, in the case of BCF, since large packaging has already advanced to a high degree, it is thought that even if labor saving is promoted, a large cost I/reduction effect will not be obtained. As for the price of raw materials, it is difficult to reduce the price of raw materials even if the scale is increased because the production scale is already large enough, and the current situation is that there is no way to develop a new manufacturing process.

適ではないものと考えられている。In this current situation, one material that should be noted is the resin recovered from the molded product layer. Due to the recent development of polyethylene terephthalate (PET) film and PET bottles, this raw material has grown to the point where we can expect a large amount of resources. However, there are many types of recovered resin, and the quality varies widely, so it has been considered that it is not suitable as a raw material for filament yarn.

れており、カルボキシル末端量の大きいものが好ましい
とされるが、カルボキシル末端基は繊維に加工されたと
きに、熱老化を促進する。PET resin has extremely good fiber-forming properties, so it is unlikely that it will become difficult to make fibers even if the quality changes slightly during the recovery operation. Various modifications have been carried out on the resin, and therefore, when the recovered resin is made into fibers, undesirable properties appear. For example, resins for blow molding are copolymerized with a considerable amount of diethylene glycol (DEC) to facilitate the molding operation, which causes a decrease in color fastness when processed into fibers after recovery. . In addition, it is required that the amount of aldehyde remaining in the resin for bottles 1 to 1 is extremely small, and a resin with a large amount of carboxyl terminals is preferable, but when processed into fibers, carboxyl terminal groups are Accelerates heat aging.

という課題を解決することを目的とする。(c) Problems to be Solved by the Invention The problem of the present invention is that it is necessary to keep the price low when using polyester filament yarn, which has somewhat poor covering power due to its specific gravity, as a carpet face yarn in the form of BCF, etc. The purpose is to solve the problem.

とを特徴とするカーペラ１〜用のポリエステルフィシメ
ン１〜糸である。(d) Means for solving the problems The present invention has a diethylene glycol (DEG) content of 1.0 to 3.0 mol% of the total glycol, and an intrinsic viscosity of 0.38.
~065, for carpellers 1~, characterized in that the content of carboxyl end groups is 30 to 85% of all end groups, and 10% or more of the raw material is polyethylene terephthalate resin recovered from molded products Polyester ficimene 1-thread.

くは１．５〜２．８モル％、最も好ましくは１８〜２．
５モル％である。If the DEC content is less than 1.0 mol %, the dyeing speed of Ficimen 1 to yarn is low and dyeing unevenness is large, which is not preferable. Further, there is a problem that the lower the DEG content, the more difficult it is to obtain raw materials. On the other hand, if it is 3.0 moles or more, the light fastness of the dyed product will be low, and therefore it is not preferable for carpets that are often exposed to light for a long time. This value is preferably between 1.5 and 2.8 mol%, most preferably between 18 and 2.8 mol%.
It is 5 mol%.
極限粘度はフェノール、テトラクロルエタンの等重量混
合物を溶媒として、３０’（：で測定しかものである。The intrinsic viscosity can only be measured at 30' (:) using a mixture of equal weights of phenol and tetrachloroethane as a solvent.

ある。If the intrinsic viscosity is 0.65 or more, it is not preferable because it becomes difficult to obtain raw materials and the uniformity of the fibers becomes poor. If it is less than 0.38, the strength of the fiber becomes extremely low and the fiber becomes fibrillated during use, and this portion appears light-colored and the fastness of the dyed product is evaluated as low, which is not preferable. The intrinsic viscosity is preferably 0.45-057.

ボキシル末端基の含有率は好ましくは４５〜７５％であ
る。If the content of carboxyl end groups is 30 mol% or less based on the total end groups, the fiber surface is highly hydrophobic and oil-soluble stains are easily adsorbed, which is a disadvantage, and the use of recovered resin becomes difficult. This is not preferable because it requires a small ratio. If the content exceeds 85 mol%, the rate of thermal deterioration and hydrolysis of the resin will increase, resulting in a decrease in the strength of the fibers during dyeing of the fibers and application of the backing to the carpet 1, as well as the durability of the carpet. I don't like it because it's inferior. The content of carboxyl end groups is preferably 45-75%.
またカルボキシル末端基の含有量は好ましくは２０〜８
０ミリ等量／ｋｇ、最も好ましくは２５〜７０ミリ等量

00% can be used, and if it is out of the preferred range, an appropriate amount of resin that falls within the preferred range is mixed and fiberized.

F can be used for the face yarn of Carpella 1~. If the number of crimps is less than 3 per 25 mm,
Since the yarn layer has a low volume, the covering properties are poor, and the yarn layer tends to collapse, which is not preferable. Number of crimp is 1 per 25mm
If there are more than 5 fibers, the yarn layer becomes soft, which makes the mat weak, the fruit clusters are likely to get tangled and collapse, and the durability is low, which is not preferable.

Heating at 0 to 170°C produces a dimensional difference of 5 to 25% between single fibers. The bulky filament I yarn due to the dimensional difference between the single fibers can be used as a BCF for the face yarn of a carpet. The most preferred BCF is one that has the ability to create dimensional differences between single fibers and has or has an appropriate number of crimps.

てかなり劣っている。(e) Since the thermal stability of the linear polyester during melting is not so good, the resin that has passed through the -bottom molding process is considerably altered in quality, and further molding causes even greater deterioration. When fibers are manufactured from such polyesters, although the strength and elastic modulus are not much different from those manufactured from new polyesters, they are considerably inferior in terms of durability, color fastness, etc.
