The following is a copolymerization reaction of # U% of cyclohexane and dimethyl alcohol, and a kind of copolyester fiber which can be deeply dyed and produced by copolymerizing the vinegar polymer. '[Prior art] ^ Polyethylene terephthalate (hereinafter referred to as PET) is a kind of polymer material, because of its good physical properties and chemical or environmental resistance, Therefore, it is often used as a raw material for clothing fibers, industrial fibers and films. However, although the polyester fiber has good physical and chemical properties, it does not have a functional group that affects dyeing when the polyester fiber is used to make clothing. Therefore, polyester fibers can only be dyed by using a dispersion dye, which will penetrate into the amorphous regions of the polyester fibers and adhere to the amorphous regions. Many studies have been devoted to expanding the amorphous area of polyester fibers, so that polyester fibers can be effectively dyed when diffusing dyes are used. In general, a copolyester polymer can be deeply dyed because it has a large non-reinforced area 'relative to PET. However, only improving the bathochrome properties of PET will reduce the good thermal properties of PET, which in turn will result in a decrease in the fastness of the dye 1240774 (color fastness). For example, J. Miliky et al., “Modified Polyester Fiber,” published in the Elsevier Journal in 1991, “disclosed a method using isophthalic acid or diethylene glycol ( Diethylene glycol (hereinafter referred to as DEG) copolymerized copolyester fiber. Although this copolyester fiber can improve its dyeability by expanding the amorphous area, it will reduce its dyeing fastness due to the molecular chain. Faster movement due to changes in thermal properties (for example, lower melting point and lower glass transition temperature). Other methods to increase the glass transition temperature of copolyester fibers' use aromatic diacids, such as Naphthalene 2,6-dicarboxylic acid; or aromatic glycol, such as ethylene oxide adduct of bisphenol A, to Increase the dyeability of copolyester fibers. For example, Japanese Patent Publication No. 57-63325,
57-66119、57-121032 及 57-212228 號中，曾詳述擴大 PET 無定型區域的方法，其係藉由單獨使用雙酚A的環氧乙 烷加成物，或使用雙酚A的環氧乙烷加成物與其他單體 (如新戊二醇neopentyl glyc〇l)的混合物來達成。然而， 上述的方法卻有其缺點，此缺點為於使用大量單體製造 共聚醋纖維時，將會導致共聚酯纖維的結晶性大幅降 低，進而造成共聚酯纖維製造上的困難，或使共聚酯纖 維具有高度的收縮，因此使得此共聚酯纖維較習知的 PET具有較差的物理性質。 1240774 同&，美國專利公報第5,681,918及6,342,579號， 專利合作條約公報第98/58〇〇8、95/〇〇575及97/3〇1〇2 號’以及歐洲專利公報帛1156,〇7〇號中均揭示環己烷 1，4 一甲醇的共聚合反應製程。 然而，因為使用超過1〇莫耳％的環己烷工〆二甲醇 來製造共聚S旨聚合物’力D上此共聚醋聚合物係為結晶 物，因此即使此纖維可藉由共聚醋聚合物製造出，但該 纖維仍會較習去口 PET纖維具有較高度的收縮。因此，以 共聚酯聚合物所製造的纖維無法作為習知p £ τ纖維的代 替物。尤其是’當30莫耳％或更高的環己烷w二甲醇 ，用於製造共聚醋聚合物日寺，由&此共聚醋聚合物幾乎 沒有結晶區，故而以此共聚酯聚合物製造纖維將是不可 能的事。 此外，上述製程中，若乙二醇成份與二酸成份的莫 耳分率比例為1.7或更高時’聚酯物的共聚合反應製程 之副反應將導致二伸乙甘醇大量地增加，以致降低了此 共聚酯聚合物的熱學性質。 【發明内容】 因此，本發明即致力於解決上述先前技術中的問 題°本發明之目的’在於提供—種可用於製造纖維的共 聚酯聚合物，及以此共聚酯聚合物所製得之可深層染色 的共聚酯纖維。其中，此共聚酯聚合物，可於確保聚對 苯二甲酸乙二醋（ΡΕΤ)極佳的熱學性質下，具擴大的無定 型區域’以使其具有可被深層染色的能力。 1240774 【實施方式】 為獲得本發明的結果，本案發明人致力於本發明上 述之目標，並徹底地研究改良共聚酯聚合物，最後獲致 根據本發明所指出的共聚酯聚合物，此共聚酯聚合物具 有一擴大的無定型區域，但玻璃轉移溫度卻未降低。 根據本發明所指出，可被使用於製造含有芳香族 (ar〇matic)化合物或脂環（alicyclic)化合物的共聚酯聚合 物之單體的例子，例如萘二羧酸、雙酚A的乙烯加成物 或環己烷1，4二甲醇。 於考量經濟效益與使用單體所製備之原紗（grey yarns)的收縮時，在本發明中較佳為使用環己烷I〆二曱 醇作為單體。 環己烷1，4二甲醇可以同分異構物（is〇me〇的形式存 在，例如順式（cis-)及反式（trans-)異構物。因此，當以環 己烷1，4二甲醇作為單體製造共聚酯聚合物時，即使僅 使用較其他單體少的環己烷1，4二甲醇用量時，該共聚 酉旨聚合物的無定型區域仍會充分地增加。 依據本發明所指出之共聚酯聚合物的製造，將於以 下有詳細的說明。 根據本發明所指出之共聚酯聚合物，係使用以乙二 醇成份為基準下，1至10莫耳％的環己烷M二甲醇 (cyclohexaneM-dimethano卜以下簡稱為 CHDM)進行共 聚合反應。 當使用超過1〇莫耳％的CHDM來製造共聚醋聚合物 時，以此共聚酯聚合物所製成之共聚酯纖維會具有高度 1240774 的收縮。尤其是當使用超過3〇 西匕取人仏士 莫耳％的CHDM製造共聚 酉曰水己斗勿日t ’ iJ：匕JdL聚两匕取人2 八♦ Sb ♦合物的無定型區域將變得太 大，而無法使用此共聚酯平人仏十… 、不0日I合物來製造共聚酯纖維。 另一方面，當使用少於1草 丄吳斗％的CHDM來製造共 聚酯聚合物時，則益法磕士、士 & η "Ν j…沄達成本發明增加共聚酯聚合物的 無定型區域之目的。 .根據本發明所指A之共聚酷聚合#，是以對笨二甲 酸（如响如⑸’以下簡料TPA)為原、料，經由τρΑ 聚合反應製程所製得。再者’共聚醋聚合物的製造方法 可以區分成使用TPA作為原料的製程，以及另—個使用 對苯二？ SH s旨（dimethyl terephthaiate)作為原料的製 。其中’以TPA作為原料的製程在經濟效^上較有競 爭力。 在含有CHDM之共聚酯聚合物的製造過程中，未反 應的TPA係為非可溶解的（n〇n-s〇iubie)且非可熔融的 (noii-nielUble)。故而，未反應的τρΑ會阻塞聚合反應裝 置中的低聚合物過濾器或聚合物過濾器，或當共聚酯聚 合物進行紡紗時，未反應的TPA會使得擠壓壓力（packed pressure)快速增加，而造成其於共聚酯聚合物及纖維製 造時之可加工性（workability)降低。 因此，酯化反應（esterification)的時間必須夠長，且 酯化反應的溫度必須在期望的高溫下，如此才能降低未 反應的TPA數量。 然而’當醋化反應的時間夠長或醋化反應溫度夠高 時’會使付不想要的副產物D E G產量增加，致使共聚醋 10 1240774 聚合物的熱穩定性下降。 及CHDM的總莫耳數與 抑止DEG之產生。根掳i 因此，較佳為降低G值（乙二醇 TPA莫耳數之比值），以盡可能 根據本發明所指出之G值是介於1.10 與1·50之間。當G值於上述範圍内，且共聚酯聚合物中 的DEG含量為0·7至2·0 wt%時，藉此可達成本發明增 加共聚酯聚合物之無定型區域的目的。同時，此共聚酯 聚合物的熱學性質並不會被降低。因此，在使用此共聚 酷聚合物製造共聚酯纖維的期間，於假撚紗製程（false twisting process)中不會產生問題。 由於根據本發明所指出的共聚酯聚合物主要係被使 用於製衣用纖維，因此可如同習知聚酯一樣，於共聚酯 5^合物中加入銳欽礦類型（anatase-type)的二氧化欽In 57-66119, 57-121032 and 57-212228, the method for expanding the amorphous area of PET was described in detail, which is by using an ethylene oxide adduct of bisphenol A alone, or using a ring of bisphenol A This is achieved by a mixture of oxyethane adducts with other monomers (such as neopentyl glycol). However, the above method has its shortcomings. This disadvantage is that when a large number of monomers are used to make the copolymerized polyester fibers, the crystallinity of the copolyester fibers will be greatly reduced, which will cause difficulties in the manufacture of the copolyester fibers, or cause Copolyester fibers have a high degree of shrinkage, thus making the copolyester fibers have poorer physical properties than conventional PET. 1240774 & U.S. Patent Gazette Nos. 5,681,918 and 6,342,579, Patent Cooperation Treaty Gazette Nos. 98 / 58〇08, 95 / 〇〇575 and 97 / 3〇1022 'and European Patent Gazette No. 1156,07 No. 0 discloses the copolymerization process of cyclohexane 1,4-methanol. However, since more than 10 mol% of cyclohexane-co-dimethanol is used to produce the copolymer, the copolymer polymer is crystalline, so even this fiber can be copolymerized with the copolymer polymer. Manufactured, but the fiber will still have a higher degree of shrinkage than conventional PET fibers. Therefore, fibers made from copolyester polymers cannot be used as a substitute for the conventional p £ τ fibers. In particular, when 30 mol% or higher of cyclohexane w dimethanol is used to make a copolymer acetic acid polymer, the copolyester polymer has almost no crystallized area, so it is a copolyester polymer. Making fibers will be impossible. In addition, in the above process, if the molar fraction ratio of the ethylene glycol component to the diacid component is 1.7 or higher, the side reaction of the copolymerization reaction process of the polyester will cause a large increase in ethylene glycol, This reduces the thermal properties of this copolyester polymer. [Summary of the Invention] Therefore, the present invention is devoted to solving the above-mentioned problems in the prior art. The object of the present invention is to provide a copolyester polymer which can be used for manufacturing fibers, and is prepared by using the copolyester polymer. Copolyester fiber that can be deeply dyed. Among them, the copolyester polymer can have an enlarged amorphous area ′ to ensure the excellent thermal properties of polyethylene terephthalate (PET), so that it can be deeply dyed. 1240774 [Embodiment] In order to obtain the results of the present invention, the inventor of the present invention devoted himself to the above-mentioned objectives of the present invention, thoroughly studied and improved the copolyester polymer, and finally obtained the copolyester polymer according to the invention. The polyester polymer has an enlarged amorphous region, but the glass transition temperature is not reduced. Examples of monomers that can be used to make copolyester polymers containing aromatic compounds or alicyclic compounds, such as naphthalenedicarboxylic acid, ethylene of bisphenol A, according to the present invention Adduct or cyclohexane 1,4 dimethanol. In consideration of economic benefits and shrinkage of grey yarns prepared by using monomers, in the present invention, cyclohexane I〆diol is preferably used as the monomer. Cyclohexane 1,4 dimethanol can exist as isomers, such as cis- and trans-isomers. Therefore, when cyclohexane 1, In the production of a copolyester polymer using 4 dimethanol as a monomer, even when only a small amount of cyclohexane 1,4 dimethanol is used compared with other monomers, the amorphous area of the copolymerized polymer is still sufficiently increased. The manufacturing of the copolyester polymer according to the present invention will be described in detail below. The copolyester polymer according to the present invention uses 1 to 10 moles based on the ethylene glycol component. % Of cyclohexane M-dimethano (hereinafter referred to as CHDM) copolymerization reaction. When more than 10 mol% of CHDM is used to produce a copolymer vinegar polymer, this copolyester polymer is made The finished copolyester fiber will have a shrinkage of 1240774 in height. Especially when using more than 30% of CHDM to make the copolymer, the water is drenched and it will not be t t iJ: JdL poly dagger Person 2 ♦ Sb ♦ The amorphous area of the compound will become too large to make This copolyester is produced by a combination of…, and 0 days to produce copolyester fibers. On the other hand, when using less than 1% of CHDM to produce copolyester polymers, it is beneficial磕 士, 士 & η " N j ... reached the purpose of the invention to increase the amorphous region of the copolyester polymer. According to the present invention, the copolymerization of the polymer A # is For example, the following brief TPA) is used as the raw material and prepared through the τρΑ polymerization process. Furthermore, the manufacturing method of the copolymerized vinegar polymer can be divided into a process using TPA as a raw material, and another using Benzene? SH s purpose (dimethyl terephthaiate) as a raw material. Among them, the process using TPA as a raw material is more economically efficient. In the manufacturing process of copolyester polymers containing CHDM, unreacted TPA is non-soluble and non-meltable (noii-nielUble). Therefore, unreacted τρΑ can block the low polymer filter or polymer filter in the polymerization device, or When copolyester polymer is spinning, it does not react TPA will make the packing pressure increase rapidly, which will cause the workability of copolyester polymers and fibers to decrease. Therefore, the esterification time must be long enough, and The temperature of the esterification reaction must be at the desired high temperature in order to reduce the amount of unreacted TPA. However, 'when the acetic acid reaction time is long enough or the acetic acid reaction temperature is high enough,' it will result in undesired by-product DEG production. The increase results in a decrease in the thermal stability of the copolymer 10 1240774 polymer. And the total mole number of CHDM and inhibit the generation of DEG. Based on this, it is preferable to reduce the G value (ratio of the ethylene glycol TPA Mohr number) so that the G value according to the present invention is between 1.10 and 1.50 as much as possible. When the G value is within the above range and the DEG content in the copolyester polymer is 0.7 to 2.0 wt%, the purpose of the present invention to increase the amorphous region of the copolyester polymer can be achieved. At the same time, the thermal properties of this copolyester polymer are not degraded. Therefore, during the production of copolyester fibers using this copolymer cool polymer, no problem occurs in the false twisting process. Since the copolyester polymer according to the present invention is mainly used for clothing fibers, it can be added to the copolyester 5 ^ compound in the same manner as the conventional polyester.
