Definitions
- the present invention relates to a polyester fiber for obtaining a fibril-like fiber which is soft and delicate to the touch, and a method for producing the same.
- Polyester fibers have various excellent properties, including mechanical properties, and are used in various applications and fields, including clothing. However, it has been said that polyester fibers are harder than natural fibers in terms of texture, do not absorb water, and are undesirable in terms of touch. Therefore, recently, to improve the properties of these polyester fibers, the water absorption has been improved by changing the cross-sectional shape of the polyester fibers, or the fibril property has been improved by modifying the polymer.
- polyester fibers are converted into microfibrils and fluff on the surface of the woven or knitted fabric.
- a method for forming the same is disclosed (for example, see Japanese Patent Application Laid-Open No. 58-298457).
- An object of the present invention is to solve the above-mentioned problems of the prior art, to provide a polyester fiber capable of promoting fibrillation uniformly and easily, and to provide a method for producing the fiber.
- the present inventors have conducted various studies to solve the above problems, and as a result, have completed the present invention.
- an object of the present invention is to provide a sodium sulfonate compound represented by the following formula (I) and / or (II) in an amount of 0.3 to 5.0% by weight and polystyrene.
- a fibril-like polyester fiber comprising: a method for producing a fiber; and subjecting the polyester fiber to at least one type of processing selected from the group consisting of pressure processing, kneading, and washing, and then subjecting the polyester fiber to a weight reduction process. Is achieved. C n H 2 n + l- S 03- N a (I )
- FIG. 1 is a photograph taken by a transmission electron microscope of a fiber after spinning and drawing in the fiber axis direction in the production process of the fibril-like fiber of Example 2 and taken with a transmission electron microscope (magnification: 3500 times).
- FIG. 2 is an electron micrograph (magnification: 3500 ⁇ ) taken in the same manner as in FIG. 1 during the fiber production process of Comparative Example 2.
- the polyester used in the present invention is intended to be a polyester whose main repeating unit is ethylene terephthalate. However, a small amount (usually 20 mol% or less based on the terephthalic acid component) of the third component other than the terephthalic acid component and the Z or ethylenedaricol component may be used.
- the polyester may be used as needed within a range that does not impair the effects of the present invention.
- Small amounts of additives such as lubricants, pigments, dyes, antioxidants, solid-state polymerization accelerators, fluorescent brighteners, antistatic agents, ultraviolet absorbers, light stabilizers, heat stabilizers, light shields, or gloss It may contain a disinfectant or the like.
- the sodium sulfonate compound is entirely dispersed in the polyester fiber or polyester fiber of the present invention, and a part of the surface is scraped by calendering, puffing, sandblasting, or pressure is applied.
- the part is intensively shaved and fibrils are formed.
- the state of fibrils differs depending on the dispersion state and cross-sectional shape of the sodium sulfonate compound in the fiber, and it has been difficult to make it constant industrially.
- a sodium sulfonate compound represented by the following formula (I) and / or (II) is added to polyester, and polystyrene and / or polymethyl methacrylate are used.
- Ph represents a phenylene group
- n represents an integer of 12 or more. Further, a preferable range of n is 12 to 18, and more preferably n is 12 to 16.
- the polystyrene to be used has the highest possible molecular weight, and the higher the glass transition temperature, the better. From the viewpoint of structural regularity, any of atactic, syndiotactic and isotactic types can obtain the fibril-like fiber of the present invention. More preferably, the glass transition temperature is 90 ° C or higher, the number average molecular weight is 100,000 or higher, the Ml (melt index) is 10 or lower, and at least one physical property in any of the syndiotactic structures. A polymer that satisfies structural properties.
- the polymethyl methacrylate preferably has a glass transition temperature of 90 ° C. or higher and a number average molecular weight of 100,000 or higher and satisfies at least one property. Polystyrene and polymethyl methacrylate are more preferably used.
- the content of these polymers needs to be 0.5 to 5.0% by weight, and preferably 0.5 to 2.0% by weight. If the content is less than 0.5% by weight, uniform fibrils cannot be formed, while if it exceeds 5.0% by weight, thread breakage tends to occur during production.
- these polymers are finally kneaded at the same melting temperature as polyester, it is important that they can be retained in the polyester without decomposition at the temperature and residence time at that time.
- the polymer is preferably incompatible with the polyester used.
- the alkyl chain of the sodium sulfonate compound In the polyester containing the sodium sulfonate compound, when the polyester is melted and discharged from the spinneret and stretched in the fiber axis direction, the alkyl chain of the sodium sulfonate compound also extends in the fiber axis direction.
