[Technical Field] The present invention relates to polyester fibers with excellent color tone and sliminess. Specifically, the present invention relates to a polyester fiber containing a specific amount of a specific higher aliphatic monocarboxylic acid ester compound, which has a good color tone, is durable, and has a slimy feel. [Prior Art and its Problems] In recent years, various modification studies have been conducted on polyester fibers in order to obtain an appearance and feel similar to natural fibers. Among these, many studies have been made on polyester fibers that have an appearance and texture similar to high-quality animal hair. In order to obtain polyester fibers with a texture similar to animal hair, it is necessary to give the polyester fibers the sliminess characteristic of animal hair. A method of incorporating ethylene or the like into polyester, and a method of attaching slippery organic compounds such as wax, fluorine compounds, and silicone compounds to polyester fibers after fiber formation have been studied. However, it is true that adding a slippery polymer such as polyorganosiloxane polytetrafluoroethylene can give polyester fibers a slimy feel, but these slippery polymers are not compatible with polyester. Because of the poor quality, a large amount of polyester fibers had to be added to give a slimy feel, resulting in significant coloration and could not be used as animal hair-like polyester fibers. Specifically, an example in which polyethylene wax is included is proposed in JP-A-53-126316. Although the purpose of this proposal is to prevent yarn breakage and fuzz from occurring during the processing process,
The acid value and molecular weight of the polyethylene wax contained are large, and the effect of imparting sliminess is small. Also, JP-A-58-9844, JP-A-57-
143521 proposes an example of containing an organic compound or a fluorine compound, but this has not resulted in improvement of good color tone and durable sliminess. On the other hand, after fiber formation, wax, fluorine compounds,
When a slippery organic compound such as a silicone compound is attached to polyester fiber, it can give a slimy feel, but it comes off when washed, dry-cleaned, etc., resulting in poor durability. [Object of the Invention] An object of the present invention is to provide a polyester fiber having good color tone, durability, and a slimy feel. [Structure of the invention] The above object is to produce a compound whose main component is a higher aliphatic monocarboxylic acid ester having 34 to 64 carbon atoms and whose acid value is 5 or less, based on 100 parts by weight of a polyester whose main repeating unit is ethylene terephthalate. This is achieved by using polyester fiber containing 0.1 to 10.0 parts by weight of The polyester in the present invention may be a homopolyester or a copolyester as long as it is a polyester mainly composed of polyethylene terephthalate. Examples of components to be copolymerized include diethylene glycol, propylene glycol, neopentyl glycol, polyalkylene glycol, 1,4-cyclohexanedimethanol, 1,
Diol components such as 4-butanediol and tetraethylene glycol, adipic acid, sebacic acid,
Dicarboxylic acid components such as phthalic acid, isophthalic acid, 2,6-naphthalenedicarboxylic acid, 5-sodium sulfoisophthalic acid, dodecanedioic acid, dimer acid, polyfunctional dicarboxylic acid components such as trimellitic acid and pyromellitic acid, p-oxyethoxy Examples include oxycarboxylic acid components such as benzoic acid. In the present invention, the main component contained in the polyester fiber is a higher aliphatic monocarboxylic acid ester having 34 to 64 carbon atoms, and examples of compounds having an acid value of 5 or less include hexyl montanate, ceryl montanate, and lignocerin. octacosyl acid, merisyl lignocerate, ceryl lignocerate,
Examples include merisil cerotate, ceryl cerotate, and naturally occurring carnauba wax, ibotarotate, and the like are also preferably used. It is necessary that the higher aliphatic monocarboxylic acid ester compound as the main component has 34 to 64 carbon atoms, preferably 40 to 62 carbon atoms. Number of carbon atoms is 34
If it is less than 20%, the ester compound will have a low molecular weight and will cause severe fouling of the die when the obtained polyester is made into fibers. If the number of carbon atoms exceeds 64, the compatibility with polyester is poor, and the effect of imparting sliminess is small. There is no limit to the number of carbon atoms in the higher aliphatic monocarboxylic acid, but those having 20 to 35 are preferred because they have a large sliminess imparting effect. As the alcohol forming the ester, monohydric or dihydric aliphatic alcohols are preferred because of their great sliminess imparting effect. The acid value of the compound used in the present invention, the main component of which is a higher aliphatic monocarboxylic acid ester having 34 to 64 carbon atoms, must be 5 or less. If the acid value exceeds 5, the effect of imparting sliminess is small. The reason for this is that the acid present in the compound generates internal particles through a reaction with the polyester polymerization catalyst, and these internal particles act as a crystal nucleating agent, increasing the crystallinity of the polyester fibers and making the threads hard and slimy. This is thought to be due to the decrease. The main component of the present invention is a higher aliphatic monocarboxylic acid ester having 34 to 64 carbon atoms, and the compound having an acid value of 5 or less needs to be contained in the polyester fiber in an amount of 0.1 to 10.0 parts by weight, and 0.5 to 64 parts by weight. It is preferable to contain 8.0 parts by weight. If the content is less than 0.1 parts by weight, the effect of imparting sliminess is small, and if it exceeds 10.0 parts by weight, the resulting polyester fibers will be severely colored. Note that the polyester fiber of the present invention may contain arbitrary additives such as stabilizers, heat-resistant agents, weather-resistant agents, antioxidants, antistatic agents, flame retardants, and matting agents such as TiO 2 as necessary. . The method for producing the polyester fiber of the present invention is not limited, and known methods of polymerization and spinning may be used. There is also no limit to the timing of adding the compound containing higher aliphatic monocarboxylic acid ester as a main component to the polyester; before the polycondensation reaction, during the polycondensation reaction,
It may be carried out either after the polycondensation reaction is finished or when the chips are dried, but it is preferable to do it after the polycondensation reaction is finished in terms of the color tone of the polyester fibers. In addition, as a method for incorporating a certain amount of a compound containing this ester as a main component into polyester fiber, a method is to dilute and mix a polyester containing a large amount of a compound containing this ester as a main component with another polyester and then spin the yarn. can also be adopted. Further, the cross-sectional shape of the polyester fiber in the present invention may be circular or may have an irregular shape such as Y-shape, T-shape, pentagon, or octagon. Further, the denier of the polyester fiber in the present invention is not particularly limited, but it is preferably 3 denier or less because the smaller the denier, the softer the texture, and the more animal hair-like texture is imparted. [Effects of the Invention] (1) Since it contains a specific amount of a specific higher aliphatic monocarboxylic acid ester compound, the polyester fiber of the present invention has good color tone and slimy feel. Therefore, it is a suitable fiber for use as an animal hair-like polyester fiber. (2) Since a specific higher aliphatic monocarboxylic acid ester compound is contained inside the polyester fiber, it will not hold up even after washing or dry cleaning.
It has excellent durability and does not lose its slimy feel. The present invention will be explained below with reference to Examples. In addition, each characteristic value of polyester and polyester fiber in Examples was measured by the following method. (Intrinsic viscosity) Determined from the value measured at 25°C in an orthochlorophenol solution. (Method for creating a tube knit) The filament to be evaluated is used to knit a tube knit fabric using a 27-gauge sock knitting machine (manufactured by Koike Kikai Seisakusho Co., Ltd.). (Scouring method) The tubular knitted fabric to be evaluated was treated with 0.2% nonionic activator [Sandet G-900 (manufactured by Sanyo Kasei Co., Ltd.)] using a conventional method.
Scouring by boiling in boiling water containing 0.2% soda ash for 5 minutes, then washing and drying. (Color tone) It is expressed as a b value measured by stacking six or more pieces of tubular knitted fabric to be evaluated and using a digital measurement color difference calculator (manufactured by Suga Test Instruments Co., Ltd.) in a state where no irradiation light is transmitted. The larger the b value, the more yellowish the color tone becomes. (Sliminess) Ten panelists touched 1 g of the tubular knitted fabric with their hands and conducted a sensory test. Five or more panelists rated it as ``slimy'', and 2 to 4 panelists rated it as ``slimy''. Those that were marked were marked △, and the others were marked ×. (Spindle dirt) Regarding the dirt on the spindle when spinning polyester containing an ester compound for 8 hours, ○ means the same stain as when spinning polyester that does not contain an ester compound, △ means it is slightly dirty, and × means it is very dirty. did. Example: 100 parts by weight of dimethyl terephthalate, 62 parts by weight of ethylene glycol, 0.06 parts by weight of calcium acetate,
Pour 0.04 parts by weight of antimony trioxide into a transesterification can and carry out the transesterification reaction using a conventional method.
After adding 0.05 parts by weight of trimethyl phosphate to the product, a polycondensation reaction was carried out. After the reaction was completed, the ester compounds shown in Table 1 were added and kneaded under reduced pressure for about 10 minutes. Table 1 shows the intrinsic viscosity of the obtained polyester. Diameter of these polyester
Melt spinning was performed using a spinneret with 24 spinning holes of 0.23 mm at a spinning temperature of 290°C and a discharge rate of 31 g/min,
The bobbin was wound at a winding speed of 1200 m/min. The obtained undrawn yarn was drawn 3.7 times using a hot roller and a hot plate method to obtain a strength of 4.9 to 5.0 g/d and an elongation.
A polyester filament of 33-37% 65 denier 24 filament was obtained. A tubular knitted fabric was prepared using this polyester filament, and the color tone, sliminess, and nozzle stain were measured. The results are shown in Table 1.
