The present invention is more useful than the above-mentioned artificial ceramics containing artificial ceramics, namely artificial fibers having excellent heat retention, deodorizing property, antimicrobial activity, coloring stability, flame retardancy, and the like, and having good reduction, It is to provide a used textile product.

In order to achieve the above object, the present inventors have searched for various effective ingredients than the artificial ceramics used in the past, and have found that there is an extremely specific effect on the popular three-segment stone made from Taiwan, which is a natural stone. Will be completed.

That is, as a first invention, a novel artificial fiber containing 1 to 15% by weight of a tricalcite powder, and as a second invention, 40 to 60% by weight of atrial stone, 30 to 50% by weight of a serpentine, and 5 to 20% by weight It provides a novel artificial fiber comprising 1 to 15% by weight of a mixed powder of% quartz modified rock and 85 to 99% by weight of polyester, polyolefin, polyamide, polyacrylonitrile, or a copolymer containing these polymers as a main component. Further, as a third invention, there is provided a fiber product in which at least 10% by weight of the artificial fiber according to the first or second invention is incorporated in a fiber material.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail with the action.

The trigeminal stone used in the present invention is a generic name that refers to a colored cordierite-based natural stone calculated on the Pacific Rim side of Taiwan, Taiwan (in Japan, also referred to as an aura stone, etc.) It is collapsed by waves and can be divided into several color systems such as blue and brown, but any one can be used.

The serpentine is very desirable because it is of high quality in Taiwan, Hwayeon Prefecture, and especially in the vicinity of Orijeon. Also known as quartz schist or "quartz schist," quartz quartzite is a siliceous crystalline schist with a high content of SiO ₂ and low Fe ₂ O ₃ or MgO with feldspar containing a large amount of silica. . Among them, quartz stony rocks calculated near the Japanese Aichiken Kitasera group contain 88.12% SiO ₂ , 8.84% Al ₂ O ₃ , 1.12% MgO and 0.75% Fe ₂ O ₃ , and the salica component It is rich in water absorption, deodorization, antibacterial and the like, and the far-infrared radiation amount is also a reasonable value, which is preferable.

In order to know the group from which useful action, such as heat retention, deodorant, and antibacterial flame retardant, which occur when these natural stone powders are contained in artificial fibers, the components of the three-stone and serpentine were analyzed. The results of the compound identification by X-ray diffraction are shown in Table 1, and the results of qualitative and quantitative analysis by fluorescent X-rays are shown in Table 2. Sample 1 is a blue triplet, Sample 2 is a brown triplet, and Sample 3 is a serpentine from Taiwan Hyeonyeon Hwajeon calculation (the sample number is used as it is).

As one means for exploring the cause of the action of the natural stone used in the present invention, the above sample was ground and press-molded to measure the far-infrared emissivity. First, the spectral emissivity (%) on the vertical axis and the wave number (cm ^-1 ) on the horizontal axis were taken for the three-wire ore, and the measurement results of Sample 1 are shown in FIG. 1 and FIG. All showed very high spectral emissivity of more than 90% over almost the entire range of wavenumber 500-2200 cm ^-1 (vkwkd 4.5-20 μm).

Next, the results of the measurement of the spectral infrared emissivity of the serpentine (sample 3) at 500 ° C. were obtained by taking the spectral reflectance (%) on the vertical axis and the wave number (cm ⁻¹ ) on the horizontal axis. The measurement result of the spectral infrared radiation emission degree is shown in FIG. 4 by taking the spectral emission emission degree (W / m ² · μm) on the vertical axis and the wavelength (μm) on the horizontal axis. The emissivity in the range of 500 degreeC and wave number 330-5000cm <^-1> (wavelength 2-3-30.3 micrometers) was 93%. Figure 3 shows the emissivity, which is the ratio of the radiant emission degree [W / m ² ] of the serpentine sample and the radiant emission degree of the thermal radiation of the black body (using the MODEL WS 153 as the black body) of the same temperature. FIG. 4 is a diagram showing the spectral emissivity used as a parameter, and FIG. 4 shows wavelengths as parameters in order to know the value of the spectral emissivity (W / m ² · μm) of the thermal radiation of a sample. The value B is written together.

Thus, it is interpreted that the high emissivity of a raw material plays a part in the effect of this invention.

Other deodorant, antimicrobial, thermal insulation and the like will be described in Examples.

In addition, it is calculated that the three-serite stone has various colors and shows the dark green color of the serpentine, and by mixing one or more of them into the artificial fiber, the artificial fiber is a relatively pale color tone, only in natural color. It has the action of coloring with a visible stable tone. This coloring does not discolor by washing | cleaning etc., and there is no possibility of discoloration even if it uses for a long time.

However, as is clear from the above analysis results, the natural stone used in the present invention contains a large number of components, and it is extremely difficult to determine which components or which combinations of these components work effectively. It has not yet been specified. However, it is estimated that the delicate combination and ratio of many components peculiar to natural stone have an effect not seen in artificial fibers incorporating artificial ceramics of a simple component, and thus exhibit the effect of the invention. In addition, the said analytical value relates to the sample of the trigeminal or serpentine used for this invention, and does not limit the composition of the trigeminal or serpentine used for this invention.

The artificial fiber of the present invention is a filament such as polyamide-based, polyester-based, polyacrylonitrile-based, polyvinyl-based, various synthetic fibers including polyolefin-based, polyurethane-based, semi-synthetic fibers including viscose rayon-based, acetate-based, etc. , Staples, cotton, piles, etc. Especially, when it is used for the fiber of polyester, polyolefin, polyamide, polyacrylonitrile, or the copolymer which has these polymers as a main component, since the effect with respect to the general use of these artificial fibers is large, it is preferable. Any of the methods for producing and spinning these artificial fibers may be used, or composite fibers may be used regardless of their fineness, cross-sectional shape, and the like.

In the artificial fiber according to the first invention, 1 to 15% by weight, preferably 1 to 5% by weight, of the three-stone powder is mixed. If the content is less than 1% by weight, the effect is not remarkable. If the content is more than 15% by weight, the properties of artificial fibers, in particular, the tensile strength may be lowered.

You may mix and use a three-line stone powder with another component. Preferred third components are the serpentine from Taiwan and quartz limite from Aichiken, Japan. The artificial fiber according to the second invention has a polyester powder such that a mixed powder of 40 to 60% by weight of tricalcite, 30 to 50% by weight of serpentine and 5 to 20% by weight of quartz stool rock becomes 1 to 15% by weight. , Polyolefins, polyamides, polyacrylonitriles, or copolymers containing these polymers as main components are mixed, and the mixed polymers are spun to prepare artificial fibers.

In particular, a mixing ratio of about 50% by weight of the three-stone powder, about 40% by weight of the serpentine powder of Taiwan and about 10% by weight of the quartz feces rock powder of Aichiken Katasera-gun, Japan is preferable. When the tricalcite powder is 30% by weight or less in the mixed powder, the added effect is inferior.

In the artificial fiber according to the first or second invention, for example, a titanium oxide powder, other pigments, a weathering agent, or the like may be added in addition to the tricalcite powder, the serpentine and / or the quartz limite powder. Moreover, for the special purpose, the zirconium carbide, silver or copper, or the powder of these oxides may be added. Adding silver or its oxide powder has the effect of removing the smell of oil.

These powders can be mixed in any of the steps of the artificial fiber manufacturing step. For example, a master chip having a high content is prepared by adding the raw material in an adjusting step, a polymerization step, or the like, and then mixing the same with a normal chip for melt spinning, or directly mixing the spinning solution with a wet spinning solution.

The size of the powder is in a range such that there is no influence on the strength of the artificial fiber and the like, and specifically, the particle size is preferably adjusted to be about 5 μm or less.

Next, the third invention will be described. 1 can manufacture various textile products using the artificial fiber which concerns on 2nd invention. It is preferable for these textile products to contain at least 10% of the artificial fibers of the invention described above in the fiber material for showing the effectiveness thereof. Generally, less than 10% will question the effect. Examples of the textile products include textile materials such as textiles, knitted fabrics, cotton, nonwoven fabrics, threads, ropes, laces and paper, underwear, children's items, handkerchiefs, corsets, outerwear, socks, gloves, protective clothing, artificial flowers, wigs, masks and Apparel, hats, beddings, footwear, belongings, portable goods, travel goods, brush goods, jewelry, furniture, medical supplies, sanitary goods, sports goods, vehicle goods, marine goods, aviation-space Articles, industrial articles, articles made of many other fibers, articles made of fibers as part of the constituent materials, and the like.

Example 1

50 kg of three samples of sample 1, 40 kg of serpentine rock of sample 3, and 10 kg of quartz feces rock from Japan's Aichiken Kitasera group were prepared, and all were crushed finely and wet-milled for about 50 minutes with a bowl mill. The obtained mud-forming mixed powder was sedimented and classified with water to remove granules, and the remainder was spread on a tray (Samtae substrate) and dried in sunlight for several days to obtain fine powder. The particle diameter was about 1-5 micrometers when observed under the microscope.

70 parts by weight of polyester chips were added to 30 parts by weight of this fine powder, followed by melt compression with an extruder to prepare a master chip. With respect to the master chip 16.6, the polyester chip was mixed at a weight ratio of 83.4, and was melt spun by a spinning nozzle having a melting temperature of 255 ± 5 ° C. and a 900 hole hole. Moreover, it stretched by 4.5 times, and made it evenly, and made the tow of about 500,000 denier and the single yarn island 3.0 denier.

This was applied to a crimper to apply crimps of 12 to 14 peaks per inch, cut into about 32 mm to prepare staple fibers (Sample 1) containing about 5% by weight of the natural stone powder. Obtained sample 1 had a beautiful light blue color.

About this sample 1, the spectral emissivity and the spectral radiance were measured at the temperature of 40 degreeC. The measurement results are shown in FIGS. 5 and 6 with the ordinate as the spectral emissivity (%) and the spectral radiance (W · cm ⁻² · str ⁻¹ cm · 10 ⁻⁴ ) and the abscissa as the wave number (cm ⁻¹ ). Display. That is, FIGS. 5 and 6 also show measurement results of the thermal radiation characteristics of the artificial fiber containing the trigeminal stone powder according to the present invention. FIG. 6 shows the spectral radiance as a parameter as the wave number, and together with the value B of the spectral radiance of the black body described above as a comparison object.

Example 2

Using the same method as in Example 1, except that the master chip obtained in Example 1 was mixed at a weight ratio of 6 and the polyester chip was 94, a staple fiber containing about 3% by weight of the natural powder was prepared (sample). 2). The obtained sample 2 had a light beautiful sky blue. Moreover, the spectral emissivity (%) and the spectral radiance (W * cm <^-2> str <^-1> cm * 10 <^-4> ) were measured at the temperature of 40 degreeC like the sample 1. The measurement results are shown in FIGS. 5 and 6 as in Example 1. FIG.

Example 3

The polyester staples of Sample 2 obtained in Example 1 were spun in yarn 20 times with an open-end spinning yarn, twisted together to form twin yarns 10, and the yarns were flat to form a letter (sample 3). did. Further, a letter (sample 4) was obtained in the same manner as sample 3 from natural cotton in the blend ratio of the polyester staple of sample 2 in a weight ratio of 1: 1. The thermal insulation, antibacterial and deodorizing properties of these samples 3 and 4 were measured.

First, heat retention was performed by the area of 225 cm <^2> of a test piece, the temperature of the test piece 35 ± 0.5 degreeC, the outdoor temperature of 20 ± 2 degreeC, and a test time of 60 minutes according to JISL1018A method, and the heat retention rate was computed by the following formula.

Thermal insulation rate (%) = (1-b / a) * 100

However, a: amount of heat dissipation when no sample is attached to the conductor

b: Heat radiation amount when a sample is attached to a heating element

For comparison, a man-made fiber made of 100% vinyl chloride (Comparative Sample 1) and a letter made of 50% vinyl chloride and 50% natural cotton (Comparative Sample 2), which are the most insulated and easily available similar letters. The heat retention rate was measured similarly to.

As a result, the thermal insulation rate,

Sample 3 38.9%

Comparative Sample 1 35.9%

Sample 4 35.1%

Comparative Sample 2 33.2%

As a result of the present invention, it has been found that the polyester side, which has conventionally been said to have a lower heat retention compared to vinyl chloride, is placed.

Next, the antimicrobial properties of the samples 3 and 4 were measured according to the processing effect evaluation test manual and microbial counting method of the antibacterial and deodorized processed product (Japanese Sanitary Processing Council of Japan). That is, the test bacteria were measured with a sample weight of 0.2 g, a culture temperature of 37 ° C., and an incubation time of 18 hours using Staphylococcus aureus, and the difference in bacterial count increase, bacterial count, and bacterial count was calculated by the following equation. In the raw samples for comparison (Comparative Sample 3), nylon standard bags were used.

Number of bacteria growth ratio = viable cell count on the test piece after incubation for 18 hours

Bacterial increase and decrease value = Log ₁₀ (viable cell count on the test piece after 18 hours incubation / viable cell count immediately before culture)

Bacterial value increase / decrease = Bacterial value increase value of raw sample

As a result, in the order of Sample 3, Sample 4, and Comparative Sample 3, the bacterial growth rate was 2.1 × 10 ² , 7.2 × 10 ^2, and 1.4 × 10 ³ , respectively, 2.3, 2.9 and 3.1, respectively. The difference was 0.8 and 0.2 respectively.

In addition, the deodorizing property measured the adsorption performance with respect to the ammonia of the sample 4, and compared with the commercially available deodorant processed blended letter (comparative sample 4) of natural cotton / polyacrylonitrile / nylon. Letters cut to a size of 50 cm × 10 cm were inserted into a brown bottle with a large opening of 1 liter, and the ammonia concentrations per hour were measured in the atmosphere of the same ammonia gas (made by Komyo Chemical Co., Ltd., Japan). Kitakawa 105S) was used, but almost the same concentration gradient was obtained.

In addition, in order to compare the fading properties, three pieces of fabrics of samples 3 and 4 cut to about 50 × 50 cm, respectively, and a blended letter of 50% of commercial polyester and 50% of cotton with similar light blue color Three units were prepared, and washed, washed with water, dehydrated, rinsed, and dehydrated with a synthetic detergent using an electric washing machine as in a general household, and dried again in daylight. This operation was repeated 10 times. Significant discoloration was seen in commercial letters, while Samples 3 and 4 showed little discoloration or discoloration.

Example 4

The same procedure as in Example 2 was carried out except that serpentine and quartz transformant were not added, and staple fibers containing about 3% by weight of tricalcite powder were prepared to be cotton (sample 5). Two sets of two-stage yo and quilts filled with commercially available 100% feathers and 2.2 kg were obtained, and one of them exchanged the inside feathers for 2.2 kg of cotton in Sample 7. These two Futons were laid in the same room, and nearly six points of corresponding positions were selected, and the detection stages of the non-contact radiation temperature crab (THI type manufactured by Tasco Japan Co., Ltd.) were inserted to compare the temperatures. When the room temperature of daytime was 26 degreeC, the average temperature of said 6 points | pieces was all 24 degreeC. When the room temperature became 15.2 ° C after 12 hours, the average temperature of the feather bed was 16.3 ° C, whereas the average temperature of the bed filled with sample 5 was 18.5 ° C. Moreover, the texture of sample 5 felt that there was a sense of stability by the texture which is inferior to a feather.

Example 5

To 95 parts of isotactic polypropylene powder, 5 parts of fine powder consisting of 5 parts of trigeminal stone, 4 parts of serpentine, and 1 part of quartz stool rock, which were adjusted in Example 1, were added to obtain a polypropylene chip using an extruder. The yarn was spun into 15 denier and 50 filament yarns in a melt spinning machine and stretched four times to prepare polypropylene filament.

The obtained fibers were processed with a rope, alternately arranged with a conventional polypropylene rope, and arranged in two rows of eight, and the weight was settled and submerged in seawater, and the adhesion state of seaweed was examined. After about a year, the ropes were lifted, and almost no seaweed was attached to the rope of the present invention, but the seaweeds began to be attached to the conventional polypropylene rope, and the difference was clearly recognized.

Example 6

In the same manner as in Example 1, the fine powder consisting of 5 parts of trigeminal stone, 4 parts of serpentine, and 1 part of quartz limite stones obtained by extending the wet grinding by the bowl mill to about 100 hours was classified into 0.5 to 2 탆. Mixed fine powder was obtained. 30 parts by weight of the mixed fine powder and 70 parts by weight of nylon 6 are melt-blended, and nylon 6 is added at a rate of 900 parts by weight, melt-mixed and spun uniformly, stretched and stretched, and single yarn 3 The denier crimped nylon was produced.

The crimped nylon was processed into underwear and socks by a usual method, and a wear test was conducted at a cold time. Twenty people were divided into two sets of 10 people, and one set was alternately worn for 5 days in the conventional crimped nylon underwear processed in the same manner and the underwear of the present invention manufactured in the test. The other pair wore socks in the same way. As for underwear, 7 out of 10 people answered that the underwear of the present invention was warmer and had better skin texture than the conventional products, and the remaining 3 people did not change. Regarding the socks, six out of 10 replied that the socks of the present invention were warmer than the conventional ones, and the remaining three remained unchanged.

Example 7

60 kg of trigeminal stone, 20 kg of serpentine, 20 kg of quartz stool rock were wet-pulverized for about 50 hours with a bowl mill, and the obtained mud-shaped mixed powder was sedimented and separated to remove granulated powder, dried and mixed to obtain a particle diameter of 1 to 5 μm. Got. To a 15% by weight dimethylsulfoxide solution of polyacrylonitrile, the mixture was added to a solution so as to have a concentration of 1% by weight in a solution, followed by wet spinning, washing with water, stretching, drying, and heat treatment, followed by crimping and cutting into polyacrylonitrile. A staple of nitrile was prepared.

Three staple yarns obtained by spinning the staples were arranged in three pieces to form pile slants, which were cut into piles, piles, and cassettes. Compared with the carpet using the conventional polyacrylonitrile fiber which was processed in exactly the same way, mold was not generated even when used in a warm and high humidity place.

As described above, the novel artificial fiber containing the trigeminal stone according to the present invention, and the fiber product containing the artificial fiber are excellent in heat retention, have antibacterial property, deodorizing property and flame retardancy, have good texture, and are various. Characteristic of the. These textile products can be beautifully colored by the selection and blending of natural stones used, and this color withstands washing and long-term use and does not discolor.
