Description
一方、このような問題を解決するため、イオン結合性分子間力の小さいカチオン可染性モノマーを共重合する技術が開示されている(例えば、特許文献3、特許文献4参照。)。イオン結合性分子間力の小さいカチオン可染性モノマーとしては、5−スルホイソフタル酸テトラブチルホスホニウムなどが例示されているが、これらのカチオン可染性モノマー共重合ポリエステルは熱安定性が悪く、常圧カチオン可染化させるため、共重合量を増加させようとしても、重合反応途中で熱分解が進行し、高分子量化させることが困難であった。さらに溶融紡糸する際の熱履歴による分解が大きく、結果として得られる糸の強度が弱くなるという欠点を有していた。また、使用する5−スルホイソフタル酸テトラブチルホスホニウムは非常に高価であり、結果として得られるカチオン可染性ポリエステルのコストが大幅に増大するという問題があった。 On the other hand, in order to solve such a problem, a technique of copolymerizing a cationic dyeable monomer having a small ion-binding intermolecular force has been disclosed (for example, see Patent Document 3 and Patent Document 4). The small cationic dyeable monomers having ion binding intermolecular force, 5 although such sulfoisophthalic acid tetrabutyl phosphonium are illustrated, these cationic dyeable monomers copolymerized polyester thermal stability is poor, normal pressure Even if an attempt is made to increase the amount of copolymerization for cationic dyeing, thermal decomposition progressed during the polymerization reaction, making it difficult to increase the molecular weight. Furthermore, there is a drawback that the decomposition due to the thermal history during melt spinning is large, and the strength of the resulting yarn is weakened. Furthermore, 5-sulfoisophthalic acid tetrabutyl phosphonium used is very expensive, the cost of the cationic dyeable polyester obtained as a result there is a problem that greatly increased.

(イ)ジエチレングリコール(DEG)含有量:
ヒドラジンヒドラート(抱水ヒドラジン)を用いてポリエステル試料チップを分解し、この分解生成物中のジエチレングリコールの含有量をガスクロマトグラフィー(ヒューレットパッカード社製(HP6850型))を用いて測定した。
(ウ)ポリエステル繊維の引張強度(破断強度)・引張伸度(破断伸度):
JIS L1013:1999 8.5に記載の方法に準拠して測定を行った。
(エ)カチオン可染性:
CATHILON BLUE CD−FRLH0.2g/L、CD−FBLH0.2g/L(いずれも保土ヶ谷化学株式会社製のカチオン可溶性染料)、硫酸ナトリウム3g/L、酢酸0.3g/Lの染色液中にて100℃で1時間、浴比1:50で染色を行い、次式により染着率を求めた。
染着率=(OD0−OD1)/OD0 ×100(%)
OD0:染色前の染液の576nmの吸光度
OD1:染色後の染液の576nmの吸光度
本発明の実施例では、染着率98%以上のものを可染性良好と判断した。
(オ)風合:
常圧下でカチオン染色した編地を10人で官能評価を実施し、柔らかさを評価した。定法で製造したポリエチレンテレフタレートホモポリマーから得られた編地を基準とし、柔らかい風合のものは○、硬い風合のものは×と判定した。

Dyeing rate = (OD 0 −OD 1 ) / OD 0 × 100 (%)
OD 0 : Absorbance at 576 nm of the dye solution before dyeing OD 1 : Absorbance at 576 nm of the dye solution after dyeing In the examples of the present invention, those having a dyeing rate of 98% or more were judged to have good dyeability.

Based on a knitted fabric obtained from a polyethylene terephthalate homopolymer produced by a conventional method, a soft texture was judged as ◯, and a hard texture as x.
