Abstract

Disclosed is a polyester fiber which is composed of a poly (trimethylene terephthalate) copolymerized with an ester forming sulfonic salt compound as a tertiary component at a copolymerizing ratio of 0.5-5 mole %; the polyester fiber having a peak temperature of a loss tangent of the fiber of 85-115 DEG C and a relation between modulus Q (g/d) and elastic recovery R (%) satisfying 0.18 <= Q/R <= 0.45. The polyester fiber can be dyed into a heavy shade under the normal pressure. Accordingly, fast dyeing of fabrics can be attained in blends of the fiber with a low thermal resistance fiber such as stretch fiber as represented by polyurethane elastic fiber, wool, silk, acetate fiber, or the like. Since dyeing of the fabric in blend with the polyester fiber can be done under normal pressure, physical properties of the low thermal resistant fiber used in the blend cannot deteriorate during dyeing. With application of an alkali reduction treatment, the polyester fiber of the invention can make a fiber having a soft and dry touch and become dyeable in brilliant color.

Description of the invention (1) The present invention relates to a polytrimethylene terephthalate fiber, and in particular, to the use of cationic dyes, disperse dyes, or both dyes for dark dyeing under normal pressure. , Polytrimethylene terephthalate fiber and cloth using it. Polytrimethylene terephthalate fiber is a soft polymer with low elasticity, excellent elastic recovery and similar properties to nylon fibers, and has both iron-free properties, dimensional stability, and yellowing resistance. Ethylene terephthalate fiber is an epoch-making fiber. Therefore, its characteristics can be applied to clothing, carpets, etc. However, polytrimethylene terephthalate fibers have problems with dyeing. That is, the known dyes used in polytrimethylene terephthalate fibers must be limited to disperse dyes, and they must be capable of dark-color dyeing under a high pressure of 110 to 120 ° C. Therefore, There are very big problems. When the dye used in the fiber is limited to a disperse dye, the sharpness of the obtained dyed matter is reduced, and the fastness to dry cleaning, the fastness to wet rubbing, and the fastness to sublimation are deteriorated. In addition, when dark-colored dyeing is to be performed, the dyeing temperature is 1 1 0 to 桴. 桴. 桴 -.f ′ 合: ^ 社印 ¾ ---------- m 1 * i yN --- ^ --- 0— T 、 -u (^ '1 room- «ruthenium note & 窬 item .; € :: item 8 wood 1 2 1 2 0 ° C High temperature will cause thermal decomposition and cannot be used to dye other mixed fabrics. For example, when using polytrimethylene terephthalate fibers and polyurethane elastic silk, wool, silk, acetate and other fibers, It is possible to obtain a mixed-use cloth with a soft touch that is not presently available. However, when the dyeing stage exceeds 110 ° C, these other fibers significantly reduce strength and whitening, and lose transparency, so there is a problem that the commerciality is significantly impaired.

Description of the invention (2) At present, there is no one that can be used under normal pressure. Polytrimethylene terephthalate fibers that can solve the above problems by dyeing dark colors of any one or both of cationic dyes and disperse dyes. Also, it is known In the technical scope, there is still no technology that can use dyes other than disperse dyes, such as cationic dyes. 'Although there is no record about the specific application of polytrimethylene terephthalate fibers, it is known that The method for improving the dyeability of cationic dyes of polyester fibers centered on polyethylene terephthalate fibers is to have a sulfonic acid metal base or a sulfonic acid class 4 sulfonium base before the polycondensation reaction is completed. Method for adding diacid to polyester and copolymerizing it (Japanese Patent Publication No. 3 4-10497, Japanese Patent Publication No. 47-22334, Japanese Patent Publication No. 5-2 3 0 7 13). However, the obtained fiber There is no dyeability of cationic dyes under normal pressure, and because of its high elasticity, only hard cloths can be obtained. In addition, known methods that can impart cationic dyeability under normal pressure are: A method for using ethylene terephthalate to copolymerize phthalic acid, adipic acid, isophthalic acid-like dicarboxylic acid or an alkyl ester thereof with a metal sulfonic acid base (for example, JP-A-2004 5 7 — 6 6 1 1 9). However, the income Fibers can increase the rate of elasticity, so only rigid fabrics can be obtained. Examples of fibers with good dyeability to disperse dyes and excellent elastic recovery properties that can reduce the elasticity rate are shown in JP 5 2 — 5 3 2 0 The polytrimethylene terephthalate fiber disclosed in the gazette, and the special publication No. 9 -5 0 9 2 2 5 discloses that the polytrimethylene terephthalate can be used for disperse dyes under normal pressure.

Description of the invention (6)-iron group shown in PR3R4R5R6 (wherein R3, R4, R5, R6 are selected from hydrogen terminal b, alkyl , The same or different groups in the aryl group and the hydroxyalkyl group, and the alkyl group having 1 to 10 carbon atoms is preferable). If M is a metal, alkali metals and alkaline earth metals are preferred. Z is a trivalent organic group, and a trivalent aryl group is preferred. When such an ester-forming sulfonate compound is copolymerized, fibers which can be dyed to a dark color with a cationic dye under normal pressure can be obtained. In addition, compared to polytrimethylene terephthalate homopolymer fibers, it is now more susceptible to disperse dyes. As for the dyeability under normal pressure of the present invention, it means that the evacuation rate of the fiber at 90 ° C can reach more than 70%. In addition, this cationic dyeable yarn has a moderate alkali-reducing characteristic. Therefore, the alkali-reducing can be used to obtain a softer feel. This alkali weight reduction means that when the cloth is heated in an alkaline aqueous solution, a part of the polymer on the surface of the fiber can be dissolved. In addition, a moderate alkali reduction means that the amount and rate of alkali reduction can be controlled industrially. Another amazing feature is that, for example, the alkali reduction rate of substantially cationic dyeable polyethylene terephthalate fibers is too fast to be controlled industrially, but the alkali reduction of the polyester fibers of the present invention The speed can be the same as that of ordinary polyethylene terephthalate fibers which are not dyed by cations, and alkali reduction can be performed by known methods. Therefore, in addition to the alkali-reduced polyester fiber of the present invention, in addition to being softer, it has characteristics such as fine pores on the surface of the fiber of several // m, which has a dry feel and makes dyeing more visible. Specific examples of preferred ester-forming sulfonate compounds are, for example, 5-sodium sulfoisophthalic acid, 5-potassium sulfoisophthalic acid, 4-sodium sulfo-2, and wood paper scales applicable to China.

Among them, ester derivatives such as methyl esters and dimethyl esters are particularly excellent because of their excellent polymer whiteness and polymerization speed. This ester-forming sulfonic acid Copolymerization ratio of acid salt compound to polytrimethylene terephthalate It is necessary that the total number of moles of all acid components constituting the polyester is 0.5 to 5 mole%. It is recommended that when the copolymerization ratio of the ester-forming sulfonate compound is less than 0.5 mole%, often It cannot be dyed with a cationic dye under pressure. In addition, when the ratio of the ester field-generating sulfonate compound exceeds 5 mol%, in addition to the deterioration of the polymer's heat resistance and polymerizability, the spinnability becomes very high. In addition, it can also cause the fiber to turn yellow. From the viewpoint of fully maintaining the dyeability and the polymerizability and spinnability of cationic dyes, it is preferably 1 to 3 mol%, particularly preferably 1.2 to 25 g. Molecular%. The aliphatic ethylene glycol having 4 to 12 carbon atoms used in the present invention, and specific examples of the "alicyclic ethylene glycol" are, for example, 1,2-butanediol, 1,3 butanediol, 1 , 4-butanediol, neopentyl glycol, 1,5-pentanediol, 1,6-hexylene glycol, heptanediol, octylene glycol, decylene glycol, dodecyl glycol , 1, 4-cyclohexanediol, 1, 3-cyclohexanediol, 1, 2-cyclohexanediol, 1, 4-cyclohexanedimethanol, 1, 3-cyclohexanedimethanol, 1 , 2-Cyclohexanedimethanol, etc. Because these ethylene glycol and polytrimethylene paper standards are applicable to the Chinese national standard (CNS) Λ'1β 仏 (2) 0χ _ 568965 V.

In addition, it has excellent polymerization speed and 1, 4-in terms of fastness to dry cleaning. Butylene glycol is particularly preferred. Poly-The copolymerization ratio of these ethylene glycol to polytrimethylene terephthalate is required to be 1.5 to 12% by weight based on the weight of the polymer. If the copolymerization ratio is less than 1.5% by weight, it is impossible to use a disperse dye to make a deep,-mouth color under normal pressure. In addition, the copolymerization ratio of ethylene glycol has a great correlation with elasticity, elastic recovery rate, melting point, glass transition point, and dyeability. Therefore, when the copolymerization ratio exceeds 12% by weight, the melting point or the glass transition point is significantly reduced, and the tactile sensation in the general use stage such as processing or ironing after heat / fixation is hardened and the cloth after dyeing is reduced. Dry cleaning fastness and other disadvantages. Among these, 2 to 10% by weight is more preferable, and 3 to 7% by weight is more preferable. • Specific examples of aliphatic or alicyclic dicarboxylic acids having a carbon number of 2 to 14 such as oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid Acid, sebacic acid, lauric acid, 2-methylglutaric acid, 2-methyl adipic acid, fumaric acid, maleic acid, itaconic acid, 1, 4-cyclohexanedicarboxylic acid, 1, 3-cyclohexanedicarboxylic acid; 1, 2, cyclohexanedicarboxylic acid, etc. Since these dicarboxylic acids are copolymerized with polytrimethylene terephthalate, they can be dyed dark with disperse dyes under normal pressure.

If the copolymerization ratio is less than 3% by weight, it cannot be dyed dark under normal pressure. When the copolymerization ratio exceeds 9% by weight, it will be significantly reduced. Because of its melting point or glass transition point, it has the disadvantages of hardening the touch during general use, such as post-heat-set processing or whole soup, and reducing the dry-cleaning fastness of dyed fabrics. 3 to 8% by weight is more preferable, and 3 to 7% by weight is more preferable. The present invention can also use polyalkylene glycol as a copolymerization component. If the copolymerization of ethylene When a diol or an acid is used as the third component, the melting point is lowered, and the spinnability is deteriorated. When the obtained fiber is post-processed, heat or a heat source may cause fusion or significant shrinkage, which may result in handleability. It becomes worse. However, when polyalkylene glycol is used as the third component, the melting point is not lowered, so there is no problem described above. Because of its large molecular weight, it causes polyalkylene glycol in the polymer. It is localized. In addition, the polyalkylene glycol used may be any one of polyethylene glycol, polytrimethylene glycol, polytetramethylene glycol, or a copolymer thereof. Ethylene glycol is the best. In addition, the average molecular weight of the polyalkylene glycol is preferably 300 to 20000. If the average molecular weight is less than 300, the polyalkylene glycol may have a higher molecular weight than the polyalkylene glycol. When polymerizing under vacuum, it is distilled off under reduced pressure. As a result, the amount of polyalkylene glycol contained in the polymer obtained will not be certain.

When the ratio of the polyalkylene glycol is less than 3% by weight, it is impossible to use a disperse dye to produce a deep, deep color under normal pressure. When the ratio of the polyalkylene glycol exceeds 10% by weight, the heat resistance of the polymer is lowered, the polymerizability is deteriorated, and the spinnability is extremely deteriorated. In addition, the glass transition point is too low, which makes the touch feel harder during general use such as processing or ironing after heat setting, and greatly reduces the dry-cleaning fastness and light fastness of dyed fabrics. Among them, 4 to 8% by weight is preferable. The polymer constituting the polyester fiber of the present invention may be copolymerized or blended with the fourth component so long as the object of the present invention is not hindered. In addition, even if a suitable fourth component is used, the above-mentioned copolymerization ratio range must be observed so as not to hinder the object of the present invention.

Excellent strength and spinnable polyester fiber. If the limiting viscosity is lower than 0.3, the spinnability will be unstable due to the low polymerization degree of the polymer. In addition, the strength of the obtained fiber will be strong. On the contrary, if the limiting viscosity exceeds 2.0, the melt viscosity will be too high to smoothly measure with a gear drum, and the spinnability will be lowered due to poor ejection.

That is, in the general manufacturing process of polytrimethylene terephthalate, it can be used in terephthalic acid or dimethyl terephthalate. The tertiary terephthalate, such as an ester, is subjected to a transesterification reaction with trimethylol and the subsequent polycondensation reaction is added at any stage. If the reactant at this time is an ester, the sulfonate compound and the aliphatic or In the case of alicyclic dicarboxylic acid or isophthalic acid, it is best to add it before transesterification because it needs to promote the reaction with trimethylol. In the case of polyalkylene glycol, in order to prevent the polymer from changing. Yellow and bumping under reduced pressure are best added after the transesterification reaction is completed. In addition, in order to have the reaction speed, the whiteness of the polymer, and the thermal stability, the paper size is applicable to Chinese national readings (CNS) Hachikawa: ίΓ (210x2 V 7: Ή · \ λαZ 568965 V.

For the reaction temperature is 200 ~ 240 ° c ° Polycondensation catalysts such as antimony oxide and titanyloxy can be used. Especially when titanyloxy is used, it can also serve as a transesterification catalyst. From the viewpoint of reaction speed and whiteness of polymers, The catalyst amount of the total carboxylic acid amount is preferably 0. 〇1 to 0.1% by weight. As for the reaction temperature, it is 240 to 180 °, and the degree of vacuum is 0.001 to 1 t 〇rr. In addition, the various additives mentioned above can be added at any stage of the polymerization process. However, in order to minimize reaction resistance, it is preferable to add at any stage after the transesterification reaction is completed. Shi Shao in M Department is printed by nc_T elimination f 'Hezhusha, and the polymer constituting the polyester fiber of the present invention prepared by the above method can also be used in inert gas such as nitrogen, argon, or often Solid phase polymerization is performed under pressure to increase the molecular weight. If this method is applied, in addition to inhibiting polymer yellowing and reducing oligomers that cause breaks or fluff, it can also increase strength.

For the polyester constituting the present invention It is important for the production method of the polymer of the fiber to maintain the whiteness of the polymer. When polytrimethylene terephthalate is copolymerized with the third component, it is easy to be colored during polymerization or spinning.

When the third component is an ester-forming sulfonate compound, the polyester fiber of the present invention is determined by dynamic viscoelasticity measurement. The peak temperature of the loss loss (hereinafter referred to as "Tmax") is 85 to 115. (: And the third component is selected from (1) an aliphatic or alicyclic ethylene glycol having a copolymerization ratio of 1 · 5 to 12% by weight and a carbon number of 4 to 12, and (2) a copolymerization ratio of 3 to 9% by weight of aliphatic or alicyclic dicarboxylic acids having 2 to 14 carbon atoms, or isophthalic acid '(3) at least one type of polyalkylene glycol having a copolymerization ratio of 3 to 10% by weight, This peak temperature is 8 5 ~ 10 ° C. Because the present invention can ensure the normal pressure dyeability and high fastness of cationic dyes and / or disperse dyes in this range. In addition, T ma X can affect non- Crystal fractions 1. The paper size is applicable to the Chinese national standard (cns Dm 叱 ---------------- 568965 V. Description of the invention (15) Sub-density, that is, Ding Ma X 値越The smaller the molecular density of the small amorphous part, therefore, it can increase the void portion where the dye enters and easily inhale the dye, so the evacuation rate can be increased. However, when using any of the third components and T ma X is lower than 8 5 ° C Because the molecules are easy to move at low temperature, it will increase the shrinkage excessively during the general use process such as general post-processing or ironing, which will make the touch worse, or reduce the fabric after dyeing. The dry-cleaning fastness. In addition, when the third component is an ester-forming sulfonate compound and T ma X exceeds 1 15 ° C, the dyeability of the object of the present invention will be reduced, and the void of the inhaled dye will be too small to make the The cationic dye is darkened without contamination. The third component is selected from (1) an aliphatic or alicyclic ethylene glycol having a carbon number of 4 to 12 with a copolymerization ratio of 1.5 to 12% by weight, (2 ) A copolymerization ratio of 3 to 9% by weight of an aliphatic or alicyclic dicarboxylic acid having a carbon number of 2 to 14 or an isophthalic acid, (3) a copolymerization ratio of 3 to 10% by weight of a polyalkylene glycol When at least one of the isogroups and T ma X exceeds 102 ° C, the void portion of the inhaled dye will be too small, and the disperse dye cannot be used to dye dark colors at normal pressure. D, printed by Xiaozi Hezhu Co., Ltd. Therefore, Tm a X is the structural factor of the fiber, so even if the polymer has the same copolymer composition, it will also be affected by the spinning temperature, anti-filament speed, elongation ratio, heat treatment temperature , Washing conditions, alkali reduction conditions, dyeing conditions and other spinning conditions and post-processing conditions have different characteristics. Especially heat The fixed temperature will cause a large change in this temperature. Therefore, it is important to use the change of the thermal fixation temperature to make T ma X 値 fall within the above range. As for the method of setting the thermal fixation, there are differences, for example, according to the present invention. In the case of polyester fibers, if the heat-fixing temperature is from room temperature to 150 °. (: T ma X will slowly rise, and it will drop significantly when it exceeds 160 ° C. Because of the change ratio of this paper scale Applicable to China's national standard (CNS) Λ (2 丨 0 ,?: Λ \. Q 一; 568965 V. Description of invention (16) will vary depending on the copolymerization ratio, so it is necessary to investigate and review the heat-fixing temperature and Tm a The relationship of X. In the present invention, when the temperature is over 115 ° C, the dyeing improvement effect is reduced without the normal-pressure dyeability. However, if it is too low, it is not good. Because the amorphous part is too thick, it has the disadvantages that it is easy to inhale the dye and easy to overflow. That is, in particular, the fastness to dry cleaning, the fastness to wet rubbing, and the fastness to washing are reduced. In addition, there are problems such as deterioration in touch feeling and reduction in size stability due to hardening during heat fixing. Although the preferred range of τ πΓ a X varies depending on the type of the third component, it is preferably 9 7 to 1 1 2 ° C when the ester-forming sulfonate compound is recognized as the third component, and (1 ) Copolymerization ratio 1.5 to 12 2% by weight of aliphatic or alicyclic ethylene glycol with 2 to 4 carbon atoms, (2) Copolymerization ratio 3 to 9% by weight of 2 to 14 aliphatic carbons with carbon number Or alicyclic dicarboxylic acid, (3) at least one of the alkylene diacids having a copolymerization ratio of 3 to 10% by weight is the first, and when the third component is, preferably 8 5 to 10 2 ° C, and 9 0 ~ 9 8 ° C is particularly good. In addition, the elastic modulus Q (g / d) of the polyester fiber of the present invention and the elastic recovery rate R (%) after being left to stand for one minute after 20% elongation need to conform to the following formula (1).

If the spinning temperature is lower than 240 tons, Because the temperature is too low, it is difficult to have a stable molten state, which will increase the plaque of the obtained fiber, or fail to obtain appropriate strength and elongation.

If the heat treatment temperature is lower than 90 ° C, the fibers will not be sufficiently crystallized and the elastic recovery will be deteriorated. If the temperature is higher than 200 ° C, it will not be stretched by cutting off the heat-treated layer. -Ordered by the Ministry of Education's secondary bid, printed by the Hezhu Club. The straightforward method will be explained below by way of example. In other words, the use of a thermal insulation field with a length of 2 to 80 cm maintained at an ambient temperature of 30 to 200 ° C below the spinning orifice is used to suppress intense cooling of the molten composite yarn extruded from the spinning orifice. The molten composite yarn is rapidly cooled to become a solid composite yarn, and then wound up with a first roller heated at a rotation speed of 3 0 0 to 3 0 0 Om / mi η, and using the first roller and speed The second roller, which is faster than the first roller, is stretched 1 to 5 to 3 times, and then wound up by a coiler that is slower than the second roller. In addition, if necessary, mixed dyeing treatment can be performed in the spinning process. In addition, it is also possible to take unstretched at a spinning speed of 3 0 ~~ 3 0 〇〇〇〇〇m / mi η, and then take up by the first roller ·, the second roller described above. In the method, after the polymer is melt extruded, the extruded molten composite yarn cannot be quenched directly at the spinning mouth, but it needs to be maintained at 30 ~ 2 0 ° C through the ambient temperature set below the spinning mouth. In the thermal insulation field with a length of 2 to 80 cm, it is better to supply the solid composite yarn obtained by quenching the molten composite yarn to the elongation step after the rapid cooling.

Description of the invention (20) The purpose of this thermal insulation field is to suppress the formation of fine crystals or extremely oriented amorphous parts of the polymer due to rapid cooling, and it is easy to extend the step. An extended amorphous structure is obtained, so the present invention can complete the necessary fiber properties. Because polytrimethylene terephthalate has a faster crystallization than, for example, polyethylene terephthalate and polyester Speed, so slow cooling is an extremely effective method for suppressing the formation of fine crystals or extremely uniform amorphous parts. If it is lower than 30 ° C, it will be difficult to increase the extension ratio due to rapid cooling. It is also easy to cause wire breakage when it is higher than 200 ° C. The temperature in this insulation field is preferably 40 ~ 200 ° C, and more preferably 50 ~ 150 ° C. In addition, the insulation The length of the field is preferably 5 ~ 30 cm. For the spinning speed of silk, the winding speed of the first roller is 300 ~ 3000m / mi η. If the spinning speed is low At 300 m / mi η, although it has excellent spinning stability, the productivity is significantly reduced today. When it exceeds 300 m / mi η, the amount of amorphous part before winding is increased. Orientation or partial crystallization, which cannot increase the stretching ratio in the stretching step, therefore, the molecules cannot be oriented and it is not easy to obtain sufficient silk strength. This speed is again preferably 1 500 to 2700 m / mi η. The amorphous part of the fiber is gently oriented, so the speed of the winder is lower than that of the first roller. Therefore, it can reduce the large shrinkage of the polyethylene terephthalate fiber. The structure is easy to absorb the dye, so it can improve the dyeability. In addition, the tension-free ratio (winding speed / second roller speed) is 0. 95 ~ 0.99, and 0. 95 ~ 0.98 is better.

Explanation of the invention (21) · 60 Q 〇m / mi η. Also, the extension ratio between the first roller and the second roller 1 · 3 ~ 3 times and 2 ~ 2 · 7 times are better. If the stretching ratio is lower than 1.3 times, the polymer cannot be fully oriented by stretching. Therefore, the strength or elastic recovery of the obtained fiber will be reduced. When it exceeds 3 times, it will raise hair quickly and cannot stretch stably. The temperature of the first roller is 40 ~ 70 ° C, because it is easy to stretch in this temperature range. Among them, 50 ° to 60 ° C is preferred. The purpose of the second roller is to perform thermosetting, so the temperature is set to 120 to 160. (:. If the temperature is lower than 120 ° C, it will lack heat fixability and will easily become thermally deformed, change the fiber over time and reduce the color rendering. When it exceeds 160 ° C, it will cause fluff or In the case of broken yarns, spinning cannot be performed stably. Among them, 120 ° C to 150 ° C is preferred. In order to obtain sufficient homogeneity and quality of the obtained fiber, the above-mentioned general method and straightening are most importantly applied. The best conditions shown in the method. In addition, the parameters of the fiber quality obtained by evaluating the applicable spinning conditions can be, for example, u%. U% is a parameter representing the homogeneity of the fiber cross section, and the above-mentioned better are applicable. The U% obtained under the conditions may be less than 2.5%, and may be less than 1.5% depending on the occasion.

(1) When the polytrimethylene terephthalate-based fibers of the present invention are mixed with the elastic fibers represented by polyurethane elastic fibers, wool, silk, acetate and other heat-resistant fibers, the heat resistance is not impaired. Low-performing fibers are dyed dark at atmospheric pressure. Especially when polytrimethylene terephthalate fiber and polyurethane elastic fiber are mixed, it can create a new feeling that has softness and touch different from the fabric mixed with nylon fiber and has easy portability. Lining. Shi Jie Leng from the Ministry of Economic Affairs ^ nc.t. Consumer Bismuth Co., Ltd. printed bismuth (2)-General trimethyl terephthalate fiber and polyurethane elastic fiber mixed cloth needs to be 1 1 〇 ~ Dyeing at 120 ° C will cause thermal degradation of polyurethane elastic fibers and can only be dyed with disperse dyes. In addition, when disperse dyes are used to dye fabrics mixed with polyurethane elastic fibers, polyurethane elastic fibers can absorb more disperse dyes than polytrimethylene terephthalate fibers and cannot be firmly fixed to the polymer. Urethane elastic fiber. For example, under dry cleaning or washing, it is easy to cause the fiber disperse dyes to be removed and contaminate the surrounding clothing, or to cause the dyes to detach, which will cause the mixed fabrics to fade and reduce the strongness of dyeing. However, when the polytrimethylene terephthalate fiber of the present invention can be dyed to a dark color using cationic dyes, disperse dyes, or both dyes under normal pressure, the aforementioned problems can be solved. That is, the first method is a polytrimethylene terephthalate dyeable with the atmospheric cationic dye of the present invention. Polyurethane elastic fibers cannot be dyed with cationic dyes. However, when using polytrimethylene terephthalate fibers that can be dyed with cationic dyes under normal pressure, it will selectively apply only China's national I?

The second method is to use polytrimethylene terephthalate fiber which can be dyed using the atmospheric pressure disperse dye of the present invention. This is because polytrimethylene terephthalate-based fibers can be modified to have normal-pressure disperse dyeability, so that disperse dyes can be prevented from migrating to polyurethane elastic fibers. (3) An example of a stretchable fiber typified by a mixed polyurethane elastic fiber is a pantyhose with strong tenacity. However, the industry lacks a high-pressure dyeing kettle necessary for general high-pressure dyeing in specialized dyeing factories. When using the polytrimethylene terephthalate fiber capable of dyeing atmospheric pressure cationic dyes or normal pressure disperse dyes of the present invention, it is possible to directly switch to nylon fiber cross-knitting tights without adding new equipment.

[Examples 2 to 7] In the consumer department, the heat treatment was carried out in the middle stage, ηΐ, and Hezhusha Printing Co., except that the type and copolymerization ratio of the ester-forming sulfonate compound were changed, and the method was performed in the same manner as in Example 1. Polymer 'spinning. The test and evaluation results of the obtained fibers are shown in Table 1. As a result, the fibers of any of the examples conformed to the formula (1), and therefore had good dyeability, fastness, and various physical properties.

The elastic recovery rate is 88%. In addition, the fiber Q / R 値 is 0.26, so it conforms to the formula (1). However, the polyester fiber obtained in this comparative example is below 95 ° C for 30 minutes. The cationic dye had an evacuation rate of 6%, so it could not be dyed in a dark color. [Comparative Example 2] Spinning was performed in the same manner as in Example 1 except that a polymer having a copolymerization ratio of SIPP of 0.3 mol% was prepared. The test results of the obtained fibers are shown in Table 1. As a result, the copolymerization ratio of the ester-forming sulfonate compound was lower than 0.5 mol%, the fiber was 95 ° C, and the cationic dye was evacuated in 30 minutes. The rate is 30%, so it cannot be dyed in dark colors.-[Comparative Example 3] Except that the copolymerization ratio of SIPP was changed to 6 mol%, the other The method of Example 1 was polymerized and spun to prepare fibers. The test and evaluation results are not shown in Table 1. In addition, the polymer produced a large number of yarn breaks in the fat yarn, so the spinnability was poor. In addition, When the fiber is dyed at 95 ° C, it will harden due to the shrinkage of the silk, so a cloth with good feel cannot be obtained. The dry-cleaning fastness of the obtained cloth is lower than that of the example.

The fibers were polymerized and spun in the same manner as in Example 1 except that the temperature of the hot roller was changed to 80 t. As a result, the hot roller can cause the filaments to fuse and cause a large number of filament breaks during stretching, so the resulting fiber will have a lot of fluffing. U% is a relatively low rate of 3.2.
