The present invention relates to functional polyester fibers.

No. 26 discloses a method of grafting hydrophilic vinyl heptamers onto highly drawn long polyester fibers, usually called drawn yarn, but such a method has a low monomer utilization rate and is uneconomical. The fibers obtained were only coarse and hard.

There are problems such as difficulty in releasing the yarn due to adhesion to the fibers and major trouble when knitting and knitting, and furthermore, such modification treatment cannot improve the rough and hard feeling of polyester long fibers.

一般に実用的なものは得られないものである。In the case of ordinary undrawn yarns and semi-drawn yarns, the monomer utilization rate is high, but the fastness of dyeing etc. decreases significantly.

By selecting such a material, it is possible to provide fibers with extremely high flexibility and rich functionality at a high monomer utilization rate that could not be obtained with conventional techniques.

下で熱処理しながら巻き取ったポリエステル系長繊維が
適用するものである。In the present invention, the above polyester is spun at a spinning speed of 4000 m.
A yarn called semi-drawn or undrawn yarn (hereinafter referred to as undrawn yarn) obtained by spinning under conditions of 1 to 200 C or less at a stretching ratio of 1 to 10%. Polyester long fibers that have been heat-treated and wound up are used.
通常この種の加工は熱板（乾熱）と、フィードローラ、
ドローローラ及びワインダーがあれば実行できる。熱板
の代わりにスチームヒータ（湿熱）を用いても良く、こ
の場合は１００℃〜１８０℃、好ましくは１２０〜１６
０℃の処理温度が選択される。This type of processing usually requires a hot plate (dry heat), a feed roller,
This can be done if you have a draw roller and winder. A steam heater (moist heat) may be used instead of a hot plate, and in this case, the temperature is 100°C to 180°C, preferably 120°C to 160°C.
A processing temperature of 0° C. is selected.
これら未延伸糸は自発伸長し、クルジを生じ易く、その
結果熱処理ムラが発生し易い傾向が強い。These undrawn yarns tend to elongate spontaneously, tend to cause curling, and as a result, have a strong tendency to cause heat treatment unevenness.
本発明はかかるクルジを排除する程度の緊張または伸長
を与える条件、すなわち１〜１０％程度の低率の条件が
選択される。In the present invention, conditions are selected that provide tension or elongation to an extent that eliminates such cruziness, that is, conditions at a low rate of about 1 to 10%.
処理時間は０．１〜１秒程度であり、好ましくは０．３
〜０．６秒である。これらは、熱処理温度との兼合いで
決定されるものである。すなわち、高い温度で長時間処
理すると糸が融着し、又、低温度での短時間処理では、
熱処理効果の発現が小さい傾向におる。たとえば、熱板
温度が１４０’Ｃ程度であれば、０．４秒程度の処理時
間が好ましい。The processing time is about 0.1 to 1 second, preferably 0.3
~0.6 seconds. These are determined in consideration of the heat treatment temperature. In other words, when treated at high temperatures for a long time, the threads fuse, and when treated at low temperatures for a short time,
The effect of heat treatment tends to be small. For example, if the hot plate temperature is about 140'C, the processing time is preferably about 0.4 seconds.
こうしてｊｑられたポリエステル系長繊維は伸度が極め
て大きく、また清水あるいは乾熱での収縮率は極めて小
さい繊維となる。特に収縮率の小さいことは、糸として
チーズ状態で染色あるいはグラフト重合等の加工を施こ
しても、加工収縮による染色むらやグラフト加工むらの
発生が少ないことを意味する。The polyester long fibers thus jqed have extremely high elongation and extremely low shrinkage when exposed to fresh water or dry heat. In particular, a low shrinkage rate means that even if the yarn is dyed in a cheese state or subjected to processing such as graft polymerization, uneven dyeing or graft processing due to processing shrinkage will be less likely to occur.
これに対して、かかる熱処理を施こしていないポリエス
テル系長繊維の未延伸糸は、乾熱、湿熱の収縮率が極め
て大きく、染色やグラフト重合改質等の後加工が行なえ
ないという問題がある。On the other hand, undrawn polyester filament yarns that have not been subjected to such heat treatment have an extremely large shrinkage rate under dry heat and wet heat, and there is a problem that post-processing such as dyeing or graft polymerization modification cannot be performed. .
本発明は、上記特定な熱処理を施したポリエステル系長
繊維が親水性ビニルモノマーでグラフト重合改質させて
も、柔軟性や風合に変化を来たさない特徴を有している
ことに着目したものである。The present invention focuses on the fact that the polyester long fibers subjected to the specific heat treatment described above have the characteristic that their flexibility and texture do not change even when they are graft polymerized and modified with a hydrophilic vinyl monomer. This is what I did.

カルボン酸などや、ビニルスルフォン酸類などが好まし

も良い。The hydrophilic vinyl monomer applicable to the present invention is preferably, for example, unsaturated carboxylic acids such as methacrylic acid, acrylic acid, itaconic acid, or vinyl sulfonic acids. Two or more kinds of these hydrophilic vinyl nitrates may be mixed.

伸糸は伸度が極めて大きいので、これらは、混繊糸とし
て他の低伸度糸と併用して使用する必要がある。かかる
併用繊維とすることにより、ひざ扱け、ひじ恢けなどの
問題は回避される。Since the undrawn yarns of graft-polymerized polyester long fibers have extremely high elongation, they must be used as mixed fiber yarns in combination with other low elongation yarns. By using such combination fibers, problems such as knee handling and elbow handling can be avoided.
混繊する糸としては、伸度が７０％以下であれば良い。The yarn to be mixed may have an elongation of 70% or less.
特に本発明で得られる機能性繊維のもつ、ソフトタッチ
、風合いを発現させるためには、高収縮タイプの糸が良
い。混繊糸としては、カバリングヤーン、空気交絡糸な
どの製品に適する手段を用いるのが好ましい。In particular, in order to express the soft touch and feel of the functional fiber obtained by the present invention, a high shrinkage type yarn is preferable. As the mixed yarn, it is preferable to use means suitable for the product, such as covering yarn and air-entangled yarn.
もらろん、伸度の大きさが問題とならない製品、たとえ
ばカーテンやシーツなどに適用する糸としては、かかる
混繊糸とする必要はないし、タテ糸、ヨコ糸のどちらか
一方を本発明の機能性繊維単独で使用してもさしつかえ
ない。Of course, it is not necessary to use such a mixed fiber yarn for products where elongation is not a problem, such as curtains and sheets, and either the warp yarn or the weft yarn can be used according to the present invention. There is no problem even if the functional fiber is used alone.
本発明の機能性繊維は、繊維中に５ｘ１０″４当量／ｇ
繊維以上のカルボキシル基を有している。The functional fiber of the present invention contains 5x10″4 equivalents/g in the fiber.
It has more carboxyl groups than fiber.

性等を発揮する。Therefore, for example, if it is in the form of a carboxylic acid, it exhibits an ion exchange function and also has adsorption or deodorizing properties for N)-13 gas and the like. Furthermore, when carboxylic acid is substituted with an alkali metal such as Na or the like to form a salt, a fiber with greater hygroscopicity and hydrophilicity is exhibited, and at the same time exhibits antistatic properties. It exhibits deodorizing properties by adsorbing gases such as hydrogen sulfide and hydrogen sulfide. In addition, when substituted with quaternary ammonium ions, it exhibits antibacterial and antifungal properties.

It turns out to be economical. In Comparative Example 1, the processing shrinkage was large and graft polymerization processing could not be performed. Comparative example-2 is
Since the monomer utilization rate is small, more monomer is required to obtain the same moisture absorption rate as in Examples 1 and 2, and a large amount of homopolymer is generated in the bath, which reduces the pump pressure of the package dyeing machine. was abnormally high, and clogging due to homopolymer and shrinkage between threads was observed. In addition, the texture was more rough and hard than that of conventional polyester.
