Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite of a halogen-containing fiber reinforced with a flame retardant, which is highly flame-retarded, and another fiber, which is excellent in feeling and hygroscopicity. And a method for producing a flame-retardant fiber composite having flame retardancy. More specifically, a halogen-containing fiber containing a large amount of an Sb compound as a flame retardant, and at least one selected from the group consisting of natural fibers and chemical fibers.
The present invention relates to a method for producing a flame-retardant fiber composite obtained by compounding a kind of fiber. In recent years, there has been a strong demand for flame retardancy not only in interiors, but also in textiles for clothing and bedding, and in addition to the flame retardancy, visual sensation, feeling, moisture absorption, washing resistance, and the like. Demands for performance such as durability are also increasing. [0003] Conventionally, research on flame retardancy of fibers has been carried out on single fibers of specific fibers such as polyester fibers and viscose rayon fibers, mainly on modacrylic fibers and polychloral fibers. Some of the products alone have excellent flame retardant performance, but at present they hardly meet the diversifying and sophisticated demands of consumers. Therefore, blending, blending, weaving, and the like of the flame-retardant fiber and other fibers are inevitably required. However, there are few studies on flame-retardation of composite fibers in which two or more kinds of different fibers are mixed. [0004] For example, a composite fiber obtained by mixing a phosphorus-containing polyester fiber and an acrylonitrile fiber (Japanese Patent Publication No. 52-2)
No. 1612) and a composite fiber obtained by mixing stannic acid and antimonic acid-containing polychloral fiber with polyester fiber, acrylic fiber, cotton, etc. (JP-A-53-6617) is effective. It is not enough in terms of flame retardancy, feeling, hygroscopicity, etc. [0005] The present invention addresses the increasingly diversified and sophisticated demands of consumers for flame retardancy, visual sensation, feeling, moisture absorption, washing resistance, durability and the like. This was done to solve the problem of no fibers being produced. Means for Solving the Problems The inventors of the present invention have made intensive studies in view of the above circumstances and as a result, have found that a fiber comprising a halogen-containing polymer containing a large amount of an Sb compound is different from other combustible fibers. It has been found that when mixed, a flame-retardant fiber composite is obtained in which the degree of decrease in flame retardancy is extremely small as compared with conventional flame-retardant fibers, and the present invention has been completed. That is, according to the present invention, halogen is used in an amount of 19.9 to 4
For a polymer containing 3.9% (wt%, the same applies hereinafter), and a polymer consisting of 40 to 65% of acrylonitrile and 60 to 35% of vinylidene chloride and vinyl chloride in total
For 85 to 15 parts of fiber (hereinafter also referred to as halogen Sb-containing fiber) obtained by melt spinning containing 12 to 50% of an Sb compound having a particle size of 2 μm or less (part by weight, the same applies hereinafter) ,
At least one fiber selected from the group consisting of natural fibers and chemical fibers (hereinafter, also referred to as other fibers) to 15 to 85 parts <br/> including Maseru that the preparation of the flame retardant fiber composite, wherein It has the desired flame retardancy and satisfies the diversified and sophisticated demands of consumers such as sight, feeling, moisture absorption, washing resistance and durability. To manufacture flame-retardant fiber composites
About the how to. [0008] The flame-retardant fiber composite is obtained by blending or blending a halogen-containing Sb-containing fiber with another fiber.
Sb-containing fibers and other fibers intertwisted, yarns produced using the blended or blended yarns, or interwoven or interwoven knitted fabrics produced using the intertwisted yarns, and combinations thereof. It is a concept that includes what is obtained by In the present invention, the halogen content is 19.9-43.9%.

The obtained fiber is used. In the polymer, 0 to 10% of a copolymerizable vinyl monomer may be copolymerized. The polymer containing 19.9 to 43.9% of halogen used in the present invention includes acrylonitrile-vinylidene chloride, acrylonitrile-vinyl chloride, acrylonitrile-vinyl chloride-vinylidene chloride, at least one of vinylidene chloride, vinylidene chloride, and acrylonitrile and Copolymers of these with a vinyl monomer copolymerizable therewith, and the like. Further, the above copolymers may be appropriately mixed and used. In addition, the polymer containing 19.9 to 43.9% of a halogen referred to in the present specification does not contain a partially acetalized polyvinyl alcohol in any form. The copolymerizable vinyl monomers include, for example, acrylic acid, esters thereof, methacrylic acid, esters thereof, acrylamide, methacrylamide, vinyl acetate, vinylsulfonic acid, salts thereof, methacrylsulfonic acid, salts thereof , Styrene sulfonic acid, salts thereof, and the like, and one or a mixture of two or more thereof can be used. The polymer containing 19.9 to 43.9% of the halogen is composed of 40 to 65% of acrylonitrile, 60 to 35% of a halogen-containing vinyl monomer and 0 to 10% of a vinyl monomer copolymerizable therewith. Since it is a union, the obtained fiber has a desired fibrous property and a feeling of an acrylic fiber, which is preferable. When at least one of the copolymerizable vinyl monomers is a sulfonic acid group-containing vinyl monomer, the dyeability is improved, which is preferable. When the halogen content of the polymer containing 19.9 to 43.9% of the halogen is less than 19.9%, it is difficult to make the fiber flame-retardant. , Etc., are not sufficient, and none of them is preferable. The particle size used in the present invention is adjusted to 2 μm or less.
The Sb compound is used as a flame retardant, and specific examples thereof include antimony oxide (Sb 2 O 3 , Sb
Etc. 2 O 4, Sb 2 O 5 ), antimony acid, inorganic antimony compounds such as antimony oxychloride and the like, but is not limited thereto. These may be used alone or in combination of two or more. The ratio of the Sb compound to the polymer containing 19.9 to 43.9% of halogen is 12 to 50%, preferably 12 to 40% , and more 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 flame retardant fiber composite. When the mixing ratio of the halogen-containing Sb-containing fiber is increased in this way, it becomes difficult to obtain performances other than the flame retardancy of the flame-retardant fiber composite, such as sight, feeling, moisture absorption, washing resistance, and durability. . On the other hand, if the amount exceeds 50%, nozzle clogging during fiber production and fiber physical properties (strength, elongation, etc.) are reduced, and problems arise in the production and quality of highly flame-retardant reinforced fibers. Is not preferred. However, less than 12 % is outside the scope of the present invention. In the present invention, the halogen content is 19.9-43.9%.
It may be used in combination with other flame retardants as long as the amount of the Sb compound relative to the containing polymer is maintained at 12 to 50%. Other flame retardants which can be used in combination with the Sb compound include, for example, aromatic halides such as hexabromobenzene, aliphatic halides such as paraffin chloride, 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,
Examples thereof include inorganic tin compounds such as stannous oxyhalide, stannic oxyhalide, and stannous hydroxide. The use amount of the other flame retardant is preferably 0 to 10%. In the present invention, the halogen Sb-containing fiber
15 parts, preferably 60 to 15 parts, more preferably 50 to 20 parts, and at least one fiber selected from the group consisting of natural fibers and chemical fibers 85 to 15 parts, preferably 85 to 40 parts, more preferably From 80 to 50 parts of the flame-retardant fiber composite according to the present invention. The usage ratio of the halogen Sb-containing fiber and at least one selected from the group consisting of natural fibers and chemical fibers is determined by the flame retardancy, visual feeling, feeling,
It is determined by performance such as moisture absorption, washing resistance and durability. The usage ratio is determined by the type and composition ratio of the halogen-containing Sb-containing fiber, and when another flame retardant is used, the type and amount of the flame retardant, the type and combination of the 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 or the chemical fiber to be mixed exceeds 85 parts, the flame retardancy of the flame-retardant fiber composite is insufficient.
When the ratio of the natural fiber and the chemical fiber to be mixed is more than 85 parts and the ratio of the natural fiber and the chemical fiber to be mixed is more than 85 parts, other flame sensation, feeling, feeling, moisture absorption, Performances such as washability and durability are not sufficient, and none of them is preferable. In order for the flame-retardant fiber composite according to the present invention to have the desired flame retardancy, and to clarify the characteristics of the natural fibers and chemical fibers to be mixed, the halogen-containing Sb-containing fiber must be 85 to 85%.
It is preferable that the ratio of the natural fiber or the chemical fiber to be mixed is 15 to 80 parts in 20 parts. The reason why the flame-retardant fiber composite according to the present invention has excellent flame retardancy is that a large amount of the Sb compound which produces a gas-type flame retardant effect is mixed with the halogen-containing Sb-containing fiber, so It is presumed that gases such as hydrogen hydride, halogen, and antimony halide are generated at a relatively low temperature, and the incombustible decomposition products cover combustible fibers. The flame retardancy of the flame-retardant fiber composite according to the present invention does not depend on the composite method such as blending, twisting, blending, blending, weaving and knitting. It is considered that the texture is very dense and uniform not only in blending, twisting, and blending but also in weaving and knitting, as compared with the size of the flame that comes into contact with the flame. Specific examples of the natural fibers include plant fibers such as cotton and hemp, animal fibers such as wool, camel, goat and silk, and specific examples of chemical fibers.
Examples include, but are not limited to, 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. These natural fibers and chemical fibers may be singly combined with a halogen-containing Sb-containing fiber.
It may be combined with the contained 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.
At the time of production, a flame retardant such as an inorganic metal compound is sufficiently pulverized with a vibration mill or the like, and the particle size is adjusted to 2 μm or less, so that there is little or no trouble in spinning such as nozzle clogging and thread breakage. Can be produced by a usual spinning method. As a method for producing a flame-retardant fiber composite,
It may be blended or blended in the state of a single fiber, may be twisted, may be twisted, and may be cross-woven or cross-knitted after each yarn is manufactured. Or may be wrapped. 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 yarn, woven fabric, knitted fabric and non-woven fabric. [0028] Optionally the flame retardant fiber composite according to the present invention, an antistatic agent, a thermal coloring preventing agent, light resistance improver, whiteness enhancers, it may be contained and devitrification inhibitor Is a matter of course. The flame-retardant fiber composite according to the present invention thus obtained has the desired flame retardancy, and also has the sensation of feeling, feeling, moisture absorption, washing resistance and durability of other fibers to be mixed. Etc. Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to only these Examples. The flame retardancy of the fibers in the examples was measured by the oxygen index method (LOI method) as follows. In general, the flame retardancy of fibers is measured and evaluated in the state of a woven fabric, but in woven fabrics, the combustibility differs depending on the number of twists, thickness, number of threads, etc. Is not able to be evaluated correctly. (Flammability) Take 2 g of cotton mixed at a predetermined ratio, divide it into eight equal parts, make eight twists of about 6 cm, make them stand upright in the holder of the oxygen index tester, and keep the sample burning for 5 cm. The minimum oxygen concentration required for the measurement was measured, and this was defined as the LOI value. The higher the LOI value, the less it burns and the higher the flame retardancy. Production Examples 1-2 Copolymers of 49.0% of acrylonitrile and 51.0% of vinyl chloride (having a halogen content of about 29%) were dissolved in acetone to a resin concentration of 27.0%. Antimony trioxide was added to a liquid obtained by diluting a part of the obtained resin solution with acetone three times 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% of the resin to prepare a spinning stock solution. The obtained spinning dope was extruded into a 30% acetone aqueous solution using a nozzle having a nozzle hole diameter of 0.08 mm and a number of holes of 300, washed with water, dried at 120 ° C., and then dried.
This was heat-stretched twice and further heat-treated at 140 ° C. for 5 minutes to obtain a halogen Sb-containing modacrylic fiber (Production Example 1). Instead of antimony trioxide, a resin obtained by adding 10% of magnesium oxide to a resin was spun similarly to obtain a modacrylic fiber (Production Example 2). Examples 1-4 and Comparative Examples 1-9 Each of the halogen Sb-containing modacrylic fiber obtained in Production Example 1 and the modacrylic fiber obtained in Production Example 2 was mixed with cotton in the ratio shown in Table 1, Samples for flammability test were prepared and LOI values were measured. The results are shown in Table 1 and illustrated in FIG. The characteristics of the fiber composite as cotton (visual feeling,
Organoleptic test was conducted to determine whether or not it had a feeling. Table 1 shows the results. In Table 1, ○ indicates that it has the characteristics (hygroscopicity) of cotton, and X indicates that it does not. [Table 1] As is clear from the results shown in Table 1 and FIG. 1, the halogenated Sb-containing modacrylic fiber used in the present invention (Preparation Example 1) and the modaacrylic fiber of Preparation Example 2 alone are more difficult to produce in the fiber of Preparation Example 2. Although it is excellent in flammability, when each of them is mixed with cotton to form a fiber composite, the use of the modal acrylic fiber of Production Example 2 is more preferable if the halogen Sb-containing modacrylic fiber used in the present invention is used. The decrease in flame retardancy was much smaller than that of the sample, and the LOI value was high when the mixing ratio of cotton was 15 parts or more, indicating that the flame retardancy was excellent. Examples 5-6 and Comparative Examples 10-11 Each of the modacrylic fibers obtained in Production Examples 1 and 2 was 70
Yarn of fiber composite with 30 parts of cotton and 30 parts of cotton (30/2)
As a result of a flameproof test of a plain weave test cloth (Example 5 and Comparative Example 10) having a length of 50 pieces / inch × 30, 40, 50 pieces / inch, respectively, by the method specified in the Fire Service Law, the production example was obtained. The one using the fiber of No. 1 passed, and the one using the fiber of Production Example 2 failed. Further, the spun yarn (20/1) made of 100% modacrylic fiber obtained in Production Examples 1 and 2 was used as weft yarn at 130 yarns / inch, and the spun yarn (30/1) made of 100% cotton. To 85
A cross-woven plain woven fabric (Example 6 and Comparative Example 11, respectively) having a weight ratio of modacrylic fiber / cotton of 50/50 (each Example 6 and Comparative Example 11) was used as a warp so as to give a book / inch. As a result, those using the fiber of Production Example 1 passed,
Those using the fibers of Production Example 2 were rejected. From the above, it can be seen that the same effect is exhibited in both the mixed spinning and the interweaving. Production Examples 3-12 Copolymers (halogen content: about 30.3%) consisting of 50% acrylonitrile, 34% vinyl chloride, 15% vinylidene chloride and 1.0% sodium methacrylatesulfonate were added to dimethylformamide at a resin concentration of 25%. It dissolved so that it might become. Into the obtained solution, a vibration mill dispersion of antimony trioxide obtained in the same manner as in Production Example 1 was added, with antimony trioxide being 0%, 2%, 6%, 8%, 10%, 12% %, 15%, 20
%, 50%, and 70% (manufacturing examples 3 to 12, respectively) to prepare spinning stock solutions. The resulting stock solution was spun in the same manner as in Production Example 1 except that the solution was extruded into a 60% aqueous dimethylformamide solution to obtain a modacrylic fiber. In this case, the spinnability was good except that in the case of Production Example 12, the nozzle was clogged and the yarn was broken. Examples 7 to 10 , Reference Examples 1 to 3 and Comparative Example
12-14 Each of 50 parts of the modacrylic fiber obtained in Production Examples 3-12 and 50 parts of cotton were mixed to obtain a fiber composite. The LOI value of the obtained fiber composite was measured, and the difference from the LOI value of the non-mixed modacrylic fiber alone was determined. Table 2 shows the results. [Table 2] From the results shown in Table 2, when the amount of antimony trioxide added is 6% or more (when those obtained in Production Examples 5 to 12 are used), the decrease in LOI value is clearly reduced. It turns out that is recognized. Especially more than 10%, even 15
%, The decrease in LOI value is small. However, as described in Production Examples 3 to 12, when the addition amount of antimony trioxide reaches 70%, problems in spinning such as nozzle clogging and thread breakage occur. Example 11 60 parts of a modacrylic fiber containing 20% of antimony trioxide obtained in Production Example 10 and various fibers 40 shown in Table 3 other than cotton
And a mixed fiber was obtained. The difference between the LOI value of the obtained conjugate fiber and the LOI value of the non-blended modacrylic fiber alone was measured. Table 3 shows the results. Comparative Example 15 Production Example except that metastannic acid was added to the resin in an amount of 20% in place of antimony trioxide used in Production Example 10.
The fiber was spun in the same manner as in Example 10 to obtain a modacrylic fiber. Using the obtained modacrylic fiber, cotton was mixed in the same manner as in Example 11 to obtain a fiber composite. The difference between the LOI value of the obtained fiber composite and the LOI value of the non-cottonized modacrylic fiber alone was measured. Table 3 shows the results. [Table 3] From the results shown in Table 3, it can be seen that the fiber composite using the modacrylic fiber obtained in Production Example 10 (Example 11 ) has a smaller decrease in LOI value as compared with the fiber composite of Comparative Example 15. Recognize. When the flame-retardant fiber composite according to the present invention is used, it has the desired flame retardancy, and is hardly evident from a single flame-retardant fiber. Textile products for interiors, clothing and bedding having characteristics such as moisture absorption, washing resistance, and durability can be obtained, and the effect of meeting the increasingly diverse and sophisticated demands of consumers can be obtained.
