【表】DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an acrylic synthetic fiber having excellent far-infrared radiation properties and a method for producing the same. (Prior technology) Far infrared rays, which are a type of electromagnetic waves and have a longer wavelength than visible light, are absorbed by air and are not attenuated by much.
The human body, which consists of fats, carbohydrates, and a large amount of water, is a good absorber of far-infrared rays. Further, far-infrared rays are said to have a deeper penetration power than near-infrared rays with short wavelengths, and have properties such as giving a mellow sense of warmth, and have recently been increasingly applied to health and medical care. Oxide ceramics are known as particles that effectively emit far-infrared rays, but ceramics also have excellent heat resistance, and products such as far-infrared heaters and far-infrared cookers have been commercialized today. . As for the application of far-infrared rays to textiles, attempts have been made to coat knitted fabrics with resins containing ceramics to increase heat retention, but although such resin treatments are effective in terms of heat retention, they also damage the fibers themselves. It has the disadvantage of impairing the texture. For example, Japanese Patent Application Laid-Open No. 63-42970 proposes a method of impregnating ceramic powder into yarn made of natural or chemical fibers as an improvement in resin processing. However, the texture and softness were not completely improved, and there were also problems with washing resistance due to post-processing. JP-A-63-152413, JP-A-63-227828
No. 63-203873, JP-A-63-203873
No. 196710, Japanese Patent Application Laid-open No. 105107/1983, etc., have proposed synthetic fibers that have a far-infrared emitting effect by blending ceramic particles into spinning raw materials, but the far-infrared effect and spinning operability are not good enough. Not enough. As a result of intensive research to improve the above-mentioned drawbacks, the present inventors discovered that the alumina-silica resin compound disclosed in Japanese Patent Publication No. 61-36866 has an excellent far-infrared radiation effect, and developed the present invention. It was completed. (Problems to be Solved by the Invention) An object of the present invention is to provide an acrylic synthetic fiber that is wash resistant and has excellent far-infrared radiation properties that can be applied over a wide range of fiber processing conditions. Still another object is to provide a method for manufacturing such far-infrared emitting acrylic synthetic fibers industrially easily and at low cost. (Means for Solving the Problems) The far-infrared emitting acrylic fiber of the present invention is an acrylic synthetic fiber composed of alumina-silica cubic primary particles having excellent far-infrared radiation characteristics. It is substantially amorphous and has an alkali metal content of 50% compared to crystalline zeolite.
It is characterized by containing 3 to 15% by weight of the following fine powder, or a fine powder whose surface is coated with a mullite metal oxide. In addition, the production method of the present invention provides an X-
A fine powder that is substantially amorphous in line diffraction and has an alkali metal content significantly lower than that of crystalline zeolite, or a fine powder whose surface is coated with a mullite metal oxide, 3 to 15% by weight. It is characterized in that it is uniformly dispersed in an organic solvent, then added to an organic solvent solution of a copolymer containing acrylonitrile, and this is spun. The acrylonitrile copolymer component used in the present invention preferably contains at least 40% by weight of acrylonitrile and has fiber-forming ability. That is, 40% by weight or more of acrylonitrile and other vinyl monomers, such as acrylic acid, methacrylic acid, or alkyl esters thereof,
An appropriate combination of vinyl acetate, vinyl chloride, vinylidene chloride, sodium allylsulfonate, sodium methallylsulfonate, sodium vinylsulfonate, sodium styrenesulfonate, sodium 2-acrylamido-2-methylpropanesulfonate, etc.
Examples include those copolymerized at a ratio of 60% by weight or less. In particular, 80% by weight or more of acrylonitrile
A copolymer containing 20% by weight or less of a vinyl monomer and a monomer containing a sulfonic acid group, or a copolymer containing 40% by weight or more of acrylonitrile and 20 to 60% by weight of vinylidene chloride and a monomer containing a sulfonic acid group is preferred. The fine powder having excellent far-infrared radiation properties used in the present invention is Silton AMT, an alumina-silica resin compound disclosed in JP-A No. 58-213031 [Mizusawa Chemical Co., Ltd.]
[manufactured by Mizusawa Chemical Co., Ltd.] or Silton FI [manufactured by Mizusawa Chemical Co., Ltd.], which is a surface coating of Silton AMT with mullite metal oxide.
It is. Silton AMT consists of cubic primary particles with a side length of 5 microns or less, having a composition with a molar ratio of Al 2 O 3 :SiO 2 in the range of 1:1.8 to 1:5, and the particles are is diffractically substantially amorphous and has a BET specific surface area of 100 m 2 /g or less,
Compared to crystalline zeolite with a molar ratio of Al 2 O 3 :SiO 2 in the same range, it contains an alkali metal content of 50% or less, especially 30% or less, and Silton FI
is a Silton AMT whose surface is coated with mullite metal oxide. Figures 1 to 3 are far-infrared emissivity characteristic diagrams; Figure 1 is for zeolite, Figure 2 is for Silton AMT, and Figure 3 is for Silton FI.
is used as a radiator. The average particle size of the fine powder used in the present invention is 0.3 to 2.0 μm, preferably 0.4 to 1.0 μm, although it depends on the grain distribution.
More preferably it is 0.4 to 0.7. If the average particle size of the fine powder is less than 0.3 μm, agglomeration tends to occur, making it difficult to achieve uniform fine dispersion even when using a dispersion device, and if it exceeds 20 μm, even if a uniform dispersion state is obtained, the fiber performance is insufficient for the purpose of the present invention. Considering this, it is not desirable. Furthermore, the presence of aggregated particles of 10 μm or more is unfavorable for operation because the spinning filtration pressure increases in a short period of time and yarn breakage occurs frequently. The amount added depends on the type of fine powder, but the content is 3 to 15% by weight based on the acrylic copolymer. If the content of the fine powder is less than 3% by weight, a sufficient far-infrared radiation effect cannot be imparted to the fiber, and if it exceeds 15% by weight, the fiber performance deteriorates and the spinnability and spinnability in spinning decrease. The method of the present invention involves uniformly and finely dispersing a fine powder with excellent far-infrared radiation properties in an organic solvent using a dispersion device, and then adding it to an organic solvent solution of an acrylonitrile copolymer and spinning it into a fiber. The fine powder is uniformly contained in the powder. Examples of the solvent used in the method of the present invention include organic solvents such as dimethylformamide, dimethylacetamide, dimethylsulfoxide, and acetone. Any known wet grinder may be used as the dispersion device, but a flow tube type grinder such as a sand grinder, pearl mill, grain mill, or dyno mill is suitable for continuously adding the dispersion liquid to the spinning dope. In the present invention, the dispersion concentration of the organic solvent solution of fine powder having excellent far-infrared properties is 5 to 40% by weight, preferably 15 to 30% by weight. If this concentration is less than 5% by weight, the concentration of the spinning stock solution decreases, and the spinnability and fiber properties decrease, although it depends on the amount of fine powder added. Also, if it exceeds 40% by weight,
A good uniform and finely dispersed state cannot be obtained, making it difficult to easily produce it industrially. Spinning can be carried out under the same conditions as for ordinary acrylic synthetic fibers, and the fibers are passed through several stages of baths, followed by sequential stretching, washing, drying, and post-treatment. (Effects of the Invention) The far-infrared ray-emitting acrylic synthetic fiber of the present invention has an excellent far-infrared ray radiating effect, has the same fiber performance as ordinary acrylic synthetic fiber, and has radiation resistance due to washing resistance and dry cleaning resistance. There is almost no decrease in effectiveness. Furthermore, the method for producing alkaline synthetic fibers of the present invention allows such fibers to be produced industrially easily and at low cost using the usual manufacturing conditions and equipment for acrylic synthetic fibers. The fibers obtained by the present invention include ordinary acrylic synthetic fibers, polyester, nylon, cotton,
It can also be used in combination with other fibers such as rayon and wool, and can be used for health clothing that has far-infrared radiation performance.
It is extremely meaningful industrially because it can be used for a wide range of purposes such as blankets, carpets, mats, socks, sheets, and futon cotton. (Examples) Hereinafter, the present invention will be specifically explained using Examples. In the examples, (%) means "% by weight". Examples 1 to 4, Comparative Examples 1 to 8 A solution of dimethylformamide (DMF), an acrylic polymer consisting of acrylonitrile (AN)/methyl acrylate (MA)/sodium methacrylsulfonate (SMAS) = 91.2/8.0/0.8, was added. Got ready. Then, after dispersing the fine powder that has far-infrared radiation characteristics superior to the acrylic copolymer in DMF using a homomixer, the homomixer added to the above acrylic copolymer solution in the amount listed in Table 1 is sufficient. The mixture was stirred to obtain a spinning stock solution. The above stock solution was spun into a 60% DMF aqueous solution at 20°C,
After stretching and washing with water while removing the solvent, an oil agent was applied to perform drying and densification. After crimping this fiber, it was subjected to a wet heat treatment at 120°C. The resulting fibers were cut and spun to produce circular knitting. The far-infrared radiation density of this knitted fabric was measured and evaluated. Comparative examples include one in which no sand grinder was used (Comparative Example 1), one in which a different amount than the above-mentioned amount was added to the acrylonitrile copolymer (Comparative Examples 2, 3, and 4), and conventional ceramics. The particles were added to an acrylonitrile copolymer (Comparative Examples 5, 6, 7, and 8). [Measurement conditions for far-infrared radiation density] Place the circular knitted fabric over a rectangular steam heater with a base size of 10cm x 5cm and a height of 30cm to control the temperature of the knitted fabric surface to 100℃, and use a power meter (manufactured by Optex) at a distance of 1m. The far-infrared radiation density (W/m 2 ) of 7 to 20 μm was measured. In addition, the spinning operability is judged by taking into account the filtration pressure, single yarn breakage, roller winding, etc. when manufactured under the conditions described in the examples, and is evaluated as ``◎'', ``〇'', ``△'', or ``×''.
I went in stages. Example 5 A DMF solution of an acrylic copolymer consisting of AN/vinylidene chloride (VCl 2 )/sodium allylsulfonate (SAS) = 57/40/3 was prepared. The acrylic copolymer was treated with 10.0% Silton FI-80 using a sand grinder to uniformly disperse it, and then added to the acrylic copolymer solution to obtain a spinning stock solution with sufficient stirring. The above-mentioned spinning stock solution was spun into a 55% DMF aqueous solution at 25° C., and after stretching and washing with water, an oil agent was applied to dry and densify it while removing the solvent. After applying a crimp to this fiber, it was subjected to a heat treatment at 115°C with moist heat. The obtained fibers are circularly knitted and washed at home for 0 to 5 minutes.
The far-infrared radiation density was measured after 10 and 20 times. Second
As shown in the table, it showed good radiation density even after washing 20 times. [Washing conditions] Using a commercially available small electric washing machine Neutral detergent 1g / Bathing 1:100 Temperature x time 40℃ x 5 minutes Washing with water 10 minutes Drying 80℃ x 1 hour [Table]
