Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a composite of a halogen-containing fiber highly flame-retarded and strengthened with a flame retardant and another fiber, and is excellent in feeling and hygroscopicity. And an interior textile product made of a flame-retardant fiber composite having flame retardancy. More specifically, an interior made of a flame-retardant fiber composite in which a halogen-containing fiber containing a large amount of a Sb compound which is a flame retardant is mixed with at least one fiber selected from the group consisting of natural fibers and chemical fibers. Regarding textile products. In recent years, there has been a strong demand for flame retardancy in interior textile products, and in addition to the flame retardancy, the visual feeling, texture, and
Demand for performance such as hygroscopicity, washing resistance, and durability is also increasing. [0003] Conventionally, research on flame retardation of fibers has been conducted mainly on modacrylic fibers and polyclar fibers, and single fibers such as polyester fibers and viscose rayon fibers have been studied. Although some of them have excellent flame-retardant performance by themselves, the current situation is that they have hardly met the increasingly diverse and sophisticated demands of consumers. Therefore, it is inevitably necessary to mix cotton, flame-spun fibers, and other fibers with each other, but there are few studies on flame-retardant composite fibers in which two or more different kinds of fibers are mixed. For example, a composite fiber obtained by mixing phosphorus-containing polyester fiber and acrylonitrile fiber (Japanese Patent Publication No. 52-2).
1612) and a composite fiber obtained by mixing stannic acid- and antimonic acid-containing polyclar fiber with polyester fiber, acrylic fiber, cotton, etc. (JP-A-53-6617) is effective, It is hard to say that it has sufficient flame retardancy, texture, and hygroscopicity. SUMMARY OF THE INVENTION The present invention meets consumers' increasingly diverse and sophisticated requirements for flame retardancy, visibility, feeling, moisture absorption, washing resistance, durability and the like. It was made to solve the problem of lacking interior textile products. The inventors of the present invention have made extensive studies in view of the above-mentioned circumstances, and as a result, have made a fiber made of a halogen-containing polymer containing a large amount of Sb compound as another flammable fiber. When mixed, it is possible to obtain a flame-retardant fiber composite having a degree of reduction in flame retardance extremely smaller than that of conventional flame-retardant fibers, and it is possible to obtain an interior fiber product that can meet the diversified demands of consumers. Heading out, the present invention has been completed. That is, according to the present invention, the halogen content is 17 to 86%.
Fiber containing 6 to 50% of Sb compound with respect to the polymer (hereinafter, halogen)
Sb-containing fiber) 85 to 15 parts (parts by weight, the same below)
And at least one fiber selected from the group consisting of natural fibers and chemical fibers (hereinafter also referred to as other fibers) 15 to 85
The present invention relates to an interior textile product made of a flame-retardant fiber composite including a part, and having desired flame retardancy, and having visual feeling, texture, hygroscopicity, washing resistance, durability, etc. It satisfies consumers' diversified and sophisticated requirements. The flame-retardant fiber composite is a mixture of a halogen Sb-containing fiber and another fiber, or a blended cotton, a halogen Sb.
Those obtained by twisting the containing fibers and other fibers, the yarn produced by using the above-mentioned blended or blended cotton, or the woven or knitted yarn produced by using the above-mentioned twisted yarn, and further by a combination thereof. The interior textile product of the present invention is a concept including those obtained, and refers to curtains, sofas and chairs, partitions, walls, carpets, mats, table cloths, etc. manufactured from them. EXAMPLES In the present invention, a polymer containing 17 to 86%, preferably 17 to 73% of halogen, and 6 to 6% of the polymer is used.
Fibers containing 50% Sb compound are used. The polymer containing 17 to 86% of halogen used in the present invention is, for example, a polymer of a halogen-containing monomer,
Examples thereof include a polymer to which a halogen-containing compound is added or a halogen-impregnated polymer obtained by post-processing. Specific examples of such a polymer include homopolymers of halogen-containing vinyl monomers such as vinyl chloride, vinylidene chloride, vinyl bromide and vinylidene bromide, or copolymers of two or more kinds, Acrylonitrile-vinylidene chloride, acrylonitrile-vinyl chloride, acrylonitrile-vinyl chloride-vinylidene chloride, acrylonitrile-vinyl bromide, acrylonitrile-vinylidene chloride-vinyl bromide, acrylonitrile-vinyl chloride-vinyl bromide, etc. Of at least one halogen-containing vinyl-based monomer such as a copolymer of acrylonitrile, vinyl chloride, vinylidene chloride, vinyl bromide and vinylidene bromide with acrylonitrile and a vinyl-based monomer copolymerizable therewith Copolymer or acrylonitrile homopolymer Polymer obtained by adding a halogen-containing compound to the body, although such halogen-containing polyester and the like, but is not limited thereto. Further, the above homopolymer or copolymer may be appropriately mixed and used. In addition,
The polymer containing 17 to 86% halogen as referred to herein does not contain partially acetalized polyvinyl alcohol in any form. Examples of the copolymerizable vinyl monomer include acrylic acid, its ester, methacrylic acid, its ester, acrylamide, methacrylamide, vinyl acetate, vinyl sulfonic acid, its salt, methacryl sulfonic acid, its salt. , Styrenesulfonic acid, salts thereof, and the like, and one kind or a mixture of two or more kinds thereof can be used. The polymer containing 17 to 86% of the halogen is acrylonitrile 30 to 70%, and the halogen-containing vinyl monomer 70.
~ 30% and vinyl monomers copolymerizable with these 0 ~
In the case of a polymer composed of 10%, the resulting fiber product is preferable because it has a desired fibrous property and a texture of acrylic fiber. Further, when at least one of the copolymerizable vinyl-based monomers is a sulfonic acid group-containing vinyl-based monomer, the dyeability is improved, which is preferable. If the halogen content in the polymer containing 17 to 86% halogen is less than 17%, it becomes difficult to make the fiber flame-retardant. If it exceeds 86%, the physical properties of the produced fiber ( Performances such as strength, elongation, heat resistance, etc.), dyeability, and feeling become insufficient, and all of them are not preferable. The Sb compound used in the present invention is used as a flame retardant, and specific examples thereof include antimony oxide (Sb ₂ O ₃ , Sb ₂ O ₄ , Sb ₂ O _5, etc.), antimonic acid, antimony oxychloride. Examples of the inorganic antimony compound include, but are not limited to. These may be used alone or in combination of two or more. Sb for polymers containing 17-86% halogen
The proportion of the compound is 6 to 50%, preferably 8 to 40%, more preferably 10 to 30%, particularly preferably 12 to 30%. If the amount is less than 6%, it is necessary to increase the mixing ratio of the halogen Sb-containing fiber in the flame-retardant fiber composite in order to obtain the flame retardancy required for the interior fiber product. When the mixing ratio of the halogen Sb-containing fiber is increased in this way, it becomes difficult to obtain performances other than the flame retardancy of the interior textile product, such as visual feeling, texture, hygroscopicity, washing resistance and durability.
On the other hand, when the amount exceeds 50%, nozzle clogging during fiber production and deterioration of fiber physical properties (strength, elongation, etc.) occur, causing problems in the production and quality of highly flame-retardant fiber. , Not preferable. In the present invention, other flame retardants may be used in combination as long as the amount of the Sb compound with respect to the polymer containing 17 to 86% halogen is maintained at 6 to 50%. Other flame retardants that can be used in combination with the Sb compound include aromatic halides such as hexabromobenzene, aliphatic halides such as chlorinated paraffin, and tris (2,3-dichloropropyl). halogen-containing phosphorus compounds such as phosphates, organic phosphorus compounds such as dibutyl amino phosphate, inorganic phosphorus compounds such as ammonium polyphosphate, MgO, Mg (OH) _2, inorganic magnesium compound such as MgCO _3, stannic oxide, metastannic acid,
Inorganic tin compounds such as stannous oxyhalide, stannous oxyhalide, and stannous hydroxide can be used. The amount of the other flame retardant used is preferably 0 to 10%. In the present invention, the halogen Sb-containing fiber 15 to
85 parts, preferably 60 to 15 parts, more preferably 50 to 20 parts and at least one kind of fiber selected from the group consisting of natural fibers and chemical fibers 85 to 15 parts, preferably 85 to 40 parts, more preferably The interior fiber product of the present invention is produced from the flame-retardant fiber composite containing 80 to 50 parts. The use ratio of the halogen Sb-containing fiber and at least one selected from the group consisting of natural fibers and chemical fibers is such that the flame retardancy, visual sensation, and feel required for the final product,
It is determined by performance such as hygroscopicity, washing resistance and durability. The usage ratio is determined by the type of halogen Sb-containing fiber and its constituent ratio, the type and amount of the flame retardant added when other flame retardant is used, the type and combination of fibers to be mixed, and the like. When the content of the halogen Sb-containing fiber is less than 15 parts, that is, when the ratio of the natural fiber and the chemical fiber to be mixed exceeds 85 parts, the flame retardancy of the interior fiber product is insufficient, while the halogen Sb-containing fiber is insufficient. When it exceeds 85 parts and the ratio of natural and chemical fibers to be mixed is less than 15 parts, it has excellent flame retardancy, but other visual feeling, texture, hygroscopicity, washing resistance and durability. Performance such as properties is not sufficient, and neither is preferable. In order for the interior textile product of the present invention to have the desired flame retardancy and to make the characteristics of the natural fiber and the chemical fiber to be mixed clear, the halogen Sb-containing fiber should be 85 to 85%.
It is preferable that the ratio of natural fibers and chemical fibers to be mixed in 20 parts is 15 to 80 parts. The reason why the interior textile product of the present invention has excellent flame retardancy is that the halogen-containing Sb-containing fiber is mixed with a large amount of an Sb compound that produces a gas-type flame-retardant effect. It is inferred that gases such as halogen and antimony halide are generated at a relatively low temperature, and the incombustible decomposition product covers combustible fibers. Further, the flame retardancy of the interior fiber product of the present invention is such that blending, twisting, blending, blending and weaving in the flame retardant fiber composite,
Compared to the size of the flame that comes in contact with flame prevention tests, etc., it shows almost the same performance without depending on the compound method such as knitting.
It is considered that the structure is extremely fine and uniform not only in mixed spinning, mixed twisting, and mixed cotton, but also in mixed weaving and knitting. Specific examples of the natural fibers include vegetable fibers such as cotton and hemp, animal fibers such as wool, camel hair, goat hair and silk, and specific examples of the chemical fibers.
Examples thereof include regenerated fibers such as viscose rayon fibers and cupra fibers, semi-synthetic fibers such as acetate fibers, and synthetic fibers such as nylon fibers, polyester fibers, and acrylic fibers, but are not limited thereto. These natural fibers and chemical fibers may be compounded with halogen Sb-containing fibers alone, and two or more kinds of halogen Sb-containing fibers may be used.
You may combine with a containing fiber. The halogen Sb-containing fiber used in the present invention contains a large amount of a flame retardant such as an inorganic metal compound.
In manufacturing, flame retardants such as inorganic metal compounds are thoroughly crushed with a vibration mill etc. and the particle size is adjusted to 2 μm or less so that spinning problems such as nozzle clogging and yarn breakage do not occur, or rarely occur. It can be produced by an ordinary spinning method. As the method for producing the flame-retardant fiber composite used for the interior fiber product of the present invention, it is possible to mix cotton in the state of single fiber, mix-spin, or twist twist each yarn. After the production, it may be woven or knitted, or may be lumped during spinning to form a slab or nep or wound. The fiber composite in the present invention is a concept including not only so-called fibers such as long fibers and short fibers, but also fiber products such as yarns, woven fabrics, knitted fabrics and nonwoven fabrics. If desired, the interior textile product of the present invention may contain an antistatic agent, a heat discoloration preventing agent, a light resistance improving agent, a whiteness improving agent, a devitrification preventing agent and the like. That is. The interior textile product of the present invention as described above has desired flame retardancy, and also has the characteristics such as visual feeling, texture, moisture absorption, washing resistance and durability of other fibers to be mixed. Have Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to such Examples. The flame retardancy of the fibers in the examples was measured by the oxygen index method (LOI method) as follows. This is because the flame retardancy of the fiber is generally measured and evaluated in the state of the woven fabric, but in the woven fabric, the flammability of the fiber itself changes due to the difference in the flammability depending on the number of twists, the thickness, and the number of threads. Because it cannot be evaluated correctly. (Flammability) 2 g of cotton mixed in a predetermined ratio
Take this, divide it into 8 equal parts, and make 8 pieces of 6 cm twist, stand them upright in the holder of the oxygen index tester, measure the minimum oxygen concentration required for this sample to continue burning for 5 cm, and use this LOI.
Value. The larger the LOI value, the harder it is to burn and the higher the flame resistance. Production Examples 1-2 A copolymer consisting of 49.0% acrylonitrile and 51.0% vinyl chloride was dissolved in acetone to a resin concentration of 27.0%. A part of the obtained resin solution was diluted three times with acetone, and antimony trioxide was added so that the solid content concentration became 50%, and dispersed using a vibration mill. This dispersion was added to and mixed with the resin solution so that antimony trioxide was 20% with respect to the resin to prepare a spinning dope. The obtained spinning dope was extruded into a 30% aqueous solution of acetone using a nozzle having a nozzle hole diameter of 0.08 mm and a number of holes of 300, washed with water and dried at 120 ° C., and then 3 times.
The halogen Sb-containing modacrylic fiber was obtained by heat-drawing twice and further heat-treating at 140 ° C. for 5 minutes (Production Example 1). Instead of antimony trioxide, 10% of magnesium oxide was added to the resin, which was spun in the same manner to obtain modacrylic fiber (Production Example 2). Examples 1 to 4 and Comparative Examples 1 to 9 The halogen Sb-containing modacrylic fibers obtained in Production Example 1 and the modacrylic fibers obtained in Production Example 2 were mixed with cotton in the proportions shown in Table 1, A sample for flammability test was prepared and LOI value was measured. The results are shown in Table 1 and also shown in FIG. The characteristics of the fiber composite as cotton (visual feeling,
A sensory test was conducted to determine whether or not the product had a texture). The results are shown in Table 1. It should be noted that in Table 1, ◯ indicates that the cotton has characteristics (hygroscopicity), and x indicates that it does not. [Table 1] As is clear from the results of Table 1 and FIG. 1, the halogen Sb-containing modacrylic fibers (Production Example 1) and the modacrylic fibers of Production Example 2 used in the present invention are more difficult than the fibers of Production Example 2 alone. Although they have excellent flammability, when these are mixed with cotton to form a fiber composite, conversely, the modal acrylic fiber of Production Example 2 is used by using the modal acrylic fiber containing halogen Sb used in the present invention. The flame retardancy was much lower than the previous ones, and when the mixing ratio of cotton was 15 parts or more, it showed a high LOI value, indicating that the flame retardancy was excellent. Examples 5-6 and Comparative Examples 10-11 70 of each of the modacrylic fibers obtained in Production Examples 1 and 2
Yarn of a fiber composite in which 30 parts of cotton and 30 parts of cotton are mixed (30/2)
A plain weaving test woven fabric of 50 warps / inch x 30, 30, 40, 50 threads / inch (each of Example 5 and Comparative Example 10) was subjected to a flameproof test by the method stipulated by the Fire Service Law, and a production example The sample using the fiber of No. 1 passed, and the sample using the fiber of Production Example 2 failed. Further, the spun yarn (20/1) of 100% modacrylic fiber obtained in Production Examples 1 and 2 was used as weft so that 130 yarns / inch were produced, and the spun yarn of 100% cotton (30/1) was used. 85
A mixed woven plain weave fabric (modal acrylic fiber / cotton in a weight ratio of 50/50 (Example 6 and Comparative Example 11), which was used as warp so as to become a book / inch, was subjected to a flameproof test by a method specified by the Fire Service Law. As a result, those using the fibers of Production Example 1 passed,
Those using the fibers of Production Example 2 failed. From the above, it can be seen that the same effect is exhibited by both mixed spinning and mixed weaving. Production Examples 3 to 12 A copolymer consisting of 50% acrylonitrile, 34% vinyl chloride, 15% vinylidene chloride and 1.0% sodium methacrylsulfonate was dissolved in dimethylformamide so that the resin concentration was 25%. An antimony trioxide vibrating mill dispersion obtained in the same manner as in Production Example 1 was added to the obtained solution.
Antimony trioxide is 0%, 2%, 6%, 8% of resin
%, 10%, 12%, 15%, 20%, 50% and 70% were added and mixed (manufacturing examples 3 to 12 respectively) to prepare spinning dope. A modacrylic fiber was obtained by spinning in the same manner as in Production Example 1 except that the obtained stock solution was extruded into an aqueous 60% dimethylformamide solution. In that case, the spinnability was good except that in the case of Production Example 12, the nozzle was clogged and yarn breakage occurred. Examples 7 to 13 and Comparative Examples 12 to 14 50 parts of each of the modacrylic fibers obtained in Production Examples 3 to 12 and 50 parts of cotton were mixed to obtain fiber composites. The LOI value of the obtained fiber composite was measured, and the difference from the LOI value of the modacrylic fiber alone without blending was determined. The results are shown in Table 2. [Table 2] From the results shown in Table 2, when the amount of antimony trioxide added was 6% or more (when the ones obtained in Production Examples 5 to 12 were used), the decrease in LOI value was clearly reduced. It can be seen that However, as described in Production Examples 3 to 12, when the added amount of antimony trioxide reaches 70%,
Spinning problems such as nozzle clogging and yarn breakage occur. Example 14 60 parts of modacrylic fiber containing 20% of antimony trioxide obtained in Production Example 10 and various fibers shown in Table 3 other than cotton 40
Part and cotton were mixed to obtain a composite fiber. The LOI value of the obtained composite fiber and the LOI value of the modacrylic fiber alone which was not mixed were measured, and the difference was obtained. The results are shown in Table 3. Comparative Example 15 Production Example except that metastannic acid was added to the resin in an amount of 20% instead of the antimony trioxide used in Production Example 10.
Spinning was performed in the same manner as in 10 to obtain modacrylic fiber. The modacrylic fiber thus obtained was mixed in the same manner as in Example 14 to obtain a fiber composite. The LOI value of the obtained fiber composite and the LOI value of the modacrylic fiber alone, which was not mixed, were measured, and the difference was obtained. The results are shown in Table 3. [Table 3] From the results shown in Table 3, the fiber composite using the modacrylic fiber obtained in Production Example 10 (Example 14) showed less decrease in LOI value than the fiber composite of Comparative Example 15. Recognize. INDUSTRIAL APPLICABILITY The interior textile product of the present invention has desired flame retardancy, and is hard to be seen from only a single flame retardant fiber. It has features such as washability and durability, and it has the effect of being able to meet the increasingly diverse and sophisticated demands of consumers.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows the relationship between the mixing ratio and the LOI value when LOI values were measured by mixing the modacrylic fibers obtained in Production Examples 1 and 2 with cotton. It is a graph.
