Description

[Technical Field]

[0001] This invention relates to a flame-retardant processing agent and a flame-retardant textile product. [Background technology]

[0002] Generally, synthetic fibers such as polyester and nylon are known to be sensitive to heat and will melt and develop holes easily when exposed to fire. One example of melting is that during outdoor activities such as camping, barbecues are common, and sparks from the fire can fly and melt synthetic fiber clothing, creating holes and posing a risk of burns. Furthermore, as described in Patent Document 1, it is known that a flame-retardant, flexible fabric can be obtained by forming a layer consisting of a composition containing an organic phosphonate and melamine on one side of a metal-coated fabric. However, given that such metal-coated fabrics have a metal layer, they cannot be considered the same as clothing fabrics used in general. Therefore, even if these metal-coated fabrics are flame-retardant, it is not necessary to process them to be superior in all aspects, including melt resistance, flame retardancy, texture, non-sticking properties, and wash durability. Furthermore, as described in Patent Document 2, it is known that flame retardancy can be obtained by attaching a phosphorus-containing flame retardant to polyester fibers and then irradiating them with an electron beam. However, this Patent Document 2 only evaluates melt resistance and wash durability, and does not require processing to be performed in a way that is superior in all aspects, such as melt resistance, flame retardancy, texture, non-stickiness, and wash durability, considering general clothing use.

[0003] Thus, obtaining a textile structure that is not merely flame-retardant, but also superior in terms of melt resistance, flame retardancy, texture, non-sticking properties, and wash durability, as described above, has not even been considered by those skilled in the art until now. Furthermore, while possessing melt-resistant and flame-retardant properties, the goal of creating a fiber structure that also excels in texture and wash durability has not yet been considered for textile structures worn on the body, such as clothing and hats, that are subject to washing, thus combining excellent melt-resistant, flame-retardant, texture, anti-sticking, and wash durability.

[0004] [Patent Document 1] Japanese Patent Publication No. 2008-285804 [Patent Document 2] Japanese Patent Application Publication No. 5-9808 [Overview of the project] [Problems that the invention aims to solve]

[0005] Therefore, the problem that the present invention aims to solve is to obtain a fibrous structure that can be used in applications where it is desirable to have excellent texture and non-sticking properties, such as towels, clothing, hats, and tents, and furthermore, to have excellent melt resistance and flame retardancy. [Means for solving the problem]

[0006] The inventors, in order to solve the above problems, conducted extensive research and found that the above problems can be solved by employing a melt-resistant flame retardant. This invention has led to a solution. In other words, the present invention is 1. A flame retardant (a) and / or polyphosphate melamine represented by the following formula (1), and a resin (b), for providing melt-resistant and flame-retardant properties to a fibrous structure containing synthetic fibers. [ka] (In the formula, R1 is hydrogen, a phenyl group, or a linear alkyl group having 1 to 6 carbon atoms, M is Mg, Al, Ca, or Zn, and m is 2 or 3.) 2. The flame retardant processing agent according to claim 1, further comprising one or more flame retardant additives (c) selected from melamine phosphate, melamine, melamine cyanurate, zinc borate, ammonium polyphosphate, aluminum hydroxide, magnesium hydroxide, brominated compounds, antimony trioxide, and antimony pentoxide. 3.

A flame-retardant fiber product obtained by treating the fiber structure with any of the flame-retardant processing agents described in 1 to 3. 5. The flame-retardant fiber product according to 4, wherein the fiber structure is composed of one or more fibers selected from polyester fibers, recycled polyester fibers, acetate fibers, triacetate fibers, nylon fibers, polyurethane fibers, polyvinyl chloride fibers, vinylidene fibers, vinylon fibers, acrylic fibers, natural cellulose fibers, and recycled cellulose fibers. 6. A flame-retardant fiber product according to 4 or 5 that retains its melt-resistant and flame-retardant properties even after being washed 10 times according to the JIS L1930:2014 C4M method. [Effects of the Invention]

[0007] According to the present invention, by treating the textile structure with a specific anti-melting flame retardant using general-purpose methods, it is possible to achieve excellent effects in terms of anti-melting properties, flame retardancy, texture, anti-sticking properties, and wash durability of the entire textile structure. [Modes for carrying out the invention]

[0008] The flame retardant processing agent of the present invention is based on containing a flame retardant (a) represented by formula (1) and / or melamine polyphosphate and a resin (b). (Flame retardant (a)) The flame retardant (a) that can be used in the present invention is [Chemical formula] (Wherein, R1 is hydrogen, a phenyl group, or a linear alkyl group having 1 to 6 carbon atoms, M is Mg, Al, Ca or Zn, and m is 2 or 3.) As the flame retardant (a) above, it is preferable that M is Al, and it is preferable that R1 is hydrogen.

[0009] The average particle diameter of the flame retardant (a) is preferably 1 to 50 μm, particularly preferably 3 to 20 μm. If the average particle diameter exceeds 50 μm, there is a risk of roughness on the coated surface or solid-liquid separation as a processing agent. If the average particle diameter is less than 1 μm, there is a risk of the generation of aggregates in the processing agent or an extreme increase in the viscosity of the processing liquid.

[0010] When the anti-melting flame retardant processing agent of the invention does not contain melamine polyphosphate and contains the flame retardant (a), it is preferable to contain 10 to 150 parts by weight of the flame retardant (a) with respect to 100 parts by weight of the resin (b) solid content, more preferably 20 parts by weight or more, still more preferably 30 parts by weight or more. Also, more preferably 120 parts by weight or less, still more preferably 110 parts by weight or less, and most preferably 100 parts by weight or less. When the content of the flame retardant (a) is less than 10 parts by weight with respect to 100 parts by weight of the resin (b) solid content, it is difficult to obtain the desired flame retardant performance and excellent anti-melting property during combustion. When it exceeds 150 parts by weight, the viscosity of the anti-melting flame retardant processing agent becomes too high and problems may occur in processing suitability.

[0011] (Melamine polyphosphate) Melamine polyphosphate is a reaction product of polymerized polyphosphoric acid obtained by subjecting phosphoric acid to a dehydration condensation reaction and melamine, and is a compound different from melamine phosphate. When the anti-melting and flame-retardant processing agent of the present invention does not contain the flame retardant (a) but contains melamine polyphosphate, it is preferably contained in an amount of 20 to 150 parts by weight, more preferably 30 parts by weight or more, still more preferably 40 parts by weight or more, and most preferably 50 parts by weight or more, based on 100 parts by weight of the solid content of the resin (b). Further preferably, it is 120 parts by weight or less, still more preferably 110 parts by weight or less, and most preferably 100 parts by weight or less. When the content of melamine polyphosphate is less than 20 parts by weight based on 100 parts by weight of the solid content of the resin (b), it is difficult to obtain the intended flame retardant performance and excellent anti-melting property during combustion. When it exceeds 150 parts by weight, the viscosity of the anti-melting and flame-retardant processing agent becomes too high, which may cause problems in processing suitability.

[0012] When the anti-melting and flame-retardant processing agent of the present invention contains both the flame retardant (a), melamine polyphosphate, and the resin, their blending ratio is preferably 90 / 10 to 30 / 70 in weight ratio of the flame retardant (a) / melamine polyphosphate. In particular, 80 / 20 to 50 / 50 is more preferable for improving the anti-melting property and flame retardancy.

[0013] When the anti-melting and flame-retardant processing agent of the present invention contains both the flame retardant (a) and melamine polyphosphate, it is preferably contained in a total amount of 20 to 150 parts by weight, more preferably 30 parts by weight or more, still more preferably 40 parts by weight or more, and most preferably 50 parts by weight or more, based on 100 parts by weight of the solid content of the resin (b). Further preferably, it is 120 parts by weight or less, still more preferably 110 parts by weight or less, and most preferably 100 parts by weight or less. When the total content of the flame retardant (a) and melamine polyphosphate is less than 20 parts by weight based on 100 parts by weight of the solid content of the resin (b), it is difficult to obtain the intended flame retardant performance and excellent anti-melting property during combustion. When it exceeds 150 parts by weight, the viscosity of the anti-melting and flame-retardant processing agent becomes too high, which may cause problems in processing suitability.

[0014] (resin (b)) In the present invention, a thermoplastic resin is preferred as the resin (b) in the anti-melt flame retardant processing agent. The thermoplastic resin is preferably one or more resins selected from acrylic resin, vinyl chloride resin, urethane resin, ethylene / vinyl acetate resin, polypropylene resin, silicone resin, polyester resin, polyamide resin, and fluororesin. In particular, when using the compound of formula (1) above, it is preferable to use two or more of silicone resin, acrylic resin, and ethylene / vinyl acetate resin in combination. This makes it easier to satisfy all the requirements for anti-melt, flame retardancy, texture, wash durability, and anti-stickiness. In particular, while water-soluble, water-dispersible, and oil-soluble agents are acceptable, water-soluble or water-dispersible agents are preferred because they allow the solvent for the anti-melt flame retardant to be aqueous. The content of this resin (b) is preferably 10 to 90% by weight of the solid content of the anti-melt flame retardant. More preferably 30% by weight or more, even more preferably 40% by weight or more, more preferably 70% by weight or less, and even more preferably 60% by weight or less.

[0015] (Flame retardant additive (c)) Flame retardant additives that may be included in the flame retardant processing agent of the present invention include one or more selected from melamine phosphate, melamine, melamine cyanurate, zinc borate, ammonium polyphosphate, aluminum hydroxide, magnesium hydroxide, brominated compounds, antimony trioxide, and antimony pentoxide.

[0016] Specific examples of brominated compounds include hexabromobenzene, pentabromotoluene, decabromodiphenylethane, tetrabromobisphenol A, dibromoneopentyl glycol, tribromoneopentyl alcohol, tris(tribromoneopentyl)phosphate, 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine, and tris(2,3-dibromopropyl) isocyanurate.

[0017] Furthermore, the content of the flame retardant auxiliary agent (c) of the present invention in the melt-resistant flame retardant processing agent of the present invention is preferably 0 to 150 parts by weight per 100 parts by weight of resin (b) solid content, more preferably 0 to 100 parts by weight, from the viewpoint of flame retardancy, excellent flame retardancy performance during combustion and melt prevention, etc., and even more preferably 10 parts by weight or more, most preferably 20 parts by weight or more. Even more preferably 95 parts by weight or less, most preferably 90 parts by weight or less.

[0018] (Other flame retardants and flame retardant enhancers) Other flame retardants and flame retardant aids that may be included in the flame retardant processing agent of the present invention include aluminum trisdiethylphosphinate, melamine pyrophosphate, melamine phthalate, borate compounds such as zinc borate, stinate compounds, carbonate compounds, copper oxides, iron oxides, ferrocene, molybdenum compounds, zirconium compounds, silica, polytetrafluoroethylene, glass fibers, and phosphate esters.

[0019] (Other additives) Additives that can be added to the flame-retardant processing agent of the present invention, within the limits that do not impair the objective of the present invention, include surfactants, colorants (dyes, pigments, etc.), foam stabilizers, water repellents, crosslinking agents, plasticizers, lightfastness improvers, antibacterial agents, insecticides, antistatic agents, defoaming agents, dispersants, and the like.

[0020] (solvent) The flame-retardant and melt-resistant processing agent of the present invention is preferably in liquid form to facilitate the processing of fibrous structures. It may also be solvent-free. The solvent used for this purpose may be water, a water-soluble organic solvent, or an oil-soluble organic solvent, but it is preferably water, a mixed solvent of water and a water-soluble organic solvent, or a water-soluble organic solvent alone, and more preferably water, or a mixed solvent of water and a water-soluble organic solvent. Suitable organic solvents include alcohol-based solvents, dialcohol-based solvents, ester-based solvents, ketone-based solvents, aliphatic hydrocarbon-based solvents, aromatic hydrocarbon-based solvents, and hydrocarbon-based solvents substituted with halogen atoms. Among these, ethanol, ethyl acetate, and methyl ethyl ketone are preferred for their suitability to the working environment and for rapid drying. The amount of solvent in the anti-melt flame retardant processing agent of the present invention can be arbitrarily determined considering the workability when processing the fibrous structure and the amount that adheres to the fibrous structure.

[0021] The composition consists of the above components, A. Flame retardant represented by the following formula (1) (a) B. Melamine cyanurate C. Resin (b) is a water-dispersible synthetic resin [ka] (In the formula, M is Al and m is 3.) In particular, a flame retardant that prevents melting when the water-dispersible synthetic resin is selected from any combination of acrylic resin and silicone resin, ethylene / vinyl acetate resin and silicone resin, or acrylic resin, silicone resin and ethylene / vinyl acetate resin is preferable in order to further enhance the effects of the present invention. Furthermore, flame-retardant fiber products obtained by processing a fibrous structure containing one or more of the following fibers—polyester fiber, a blend of polyester fiber and cotton, a blend of polyester fiber and rayon, and nylon fiber—with this combination of flame-retardant agents are also preferable in order to further enhance the effects of the present invention.

[0022] (Fiber structures) The flame-retardant and melt-proofing agent of the present invention does not constitute a molded body or fiber structure by itself, but is used as a surface treatment agent for fiber structures, and, if the fiber structure is porous, as an agent that impregnates the pores. The basis weight, thickness, structure, etc. of the fiber structure can be known. The fibrous structures treated with the flame-retardant anti-melting agent of the present invention include, if necessary, tows, filaments, twisted yarns, spun yarns, padding (stuffing), paper, nonwoven fabrics, woven fabrics, knitted fabrics, etc., obtained by known means and colored as needed. The fibrous structure is composed of one or more fibers selected from known synthetic fibers such as polyester fibers, recycled polyester fibers, acetate fibers, triacetate fibers, nylon fibers, polyurethane fibers, polyvinyl chloride fibers, vinylidene fibers, vinylon fibers, acrylic fibers, natural cellulose fibers, and recycled cellulose fibers such as rayon fibers. Furthermore, the fiber structure can be used in industrial materials such as filters, separators, vehicle interior materials and seats, materials such as tents and banners, clothing products such as underwear, innerwear, outerwear, scarves, stoles, hats, ear loops, and gloves, interior products such as wallpaper, shoji paper, carpets, curtains, and upholstered furniture, and bedding such as blankets, duvet covers, sheets, and pillowcases. It is particularly preferable that the fiber structure be used in applications where tactile sensation is important, such as in clothing products such as underwear, innerwear, outerwear, scarves, stoles, hats, ear loops, and gloves, and bedding such as blankets, duvet covers, sheets, and pillowcases. Furthermore, materials containing fibers that melt upon heating are preferred, and these are intended for repeated use after washing as needed.

[0023] The fibrous structures in the present invention, which are treated with a melt-resistant and flame-retardant processing agent to be given melt-resistant and flame-retardant properties, may further contain, as necessary, surfactants, colorants (dyes, pigments, etc.), foam stabilizers, water repellents, crosslinking agents, plasticizers, lightfastness enhancers, antibacterial agents, insecticides, antistatic agents, defoaming agents, dispersants, etc., which are known for use in fibrous structures.

[0024] (Flame-retardant treatment) As a method for processing a fibrous structure using the anti-melting flame retardant processing agent of the present invention, known methods of treating the fibrous structure with a liquid can be employed, such as immersing the fibrous structure in the anti-melting flame retardant processing agent, directly coating or spraying the anti-melting flame retardant processing agent onto the fibrous structure, and then drying it as necessary. In this invention, if R1 in formula (1) is hydrogen, and the resin is polyethylene resin or polyurethane resin, and the flame retardant of formula (1) and the resin are kneaded in advance, molded into a film, and then bonded to the fibers using a press, the melt resistance and flame retardancy may be slightly inferior. Also, if R1 is a hydrocarbon or the like, and the molded article is obtained from a composition containing it in polyurethane resin, then processing a separately prepared fiber structure, as in this invention, yields superior results in terms of melt resistance, flame retardancy, texture, and wash durability. The amount of the flame-retardant processing agent of the present invention that adheres to the fibrous structure is preferably 20 to 140 g / m² as the amount of solid content adhering to the fibrous structure. 2 Comfortably 30-120g / m 2 More preferably 40-100 g / m² 2 That is the case. [Examples]

[0025] The present invention will be described in detail below with reference to examples, but the present invention is not limited to these specific examples. It is not. Furthermore, in the examples and comparative examples, unless otherwise specified, percentages are used and parts are used. It is based on weight. The values ​​in each table represent the amount of solid content (g / m²) of each component of the flame retardant agent adhering to the fiber structure. 2 ) The flame-retardant and anti-melting agent itself contains an aqueous solvent before being applied to the fibrous structure. In the table, "water-based" in terms such as "water-based urethane resin" means that the urethane resin was blended as a resin that had been dispersed or dissolved in an aqueous solvent beforehand. "Solvent-based" means that the resin was blended as a resin that had been dissolved or dispersed in an organic solvent.

[0026] (Examples and Comparative Examples) The flame retardant and anti-melting agents used in the examples and comparative examples were obtained by mixing the components and proportions listed in the table. The weight ratio of the amount of each component adhering to the fiber structure is the same as the weight ratio of each component in the flame retardant and anti-melting agent. These flame-retardant and anti-melting agents were used to treat fiber structures using the following method, and the following tests were conducted. The results of treating a blended fiber of polyester fiber / cotton (mixing ratio 65 / 35) (basis weight 110 g / m 2 ) are shown in Tables 1 and 2. The results of treating 100% polyester fiber (basis weight 150 g / m 2 ) are shown in Tables 3 and 4. The results of treating 100% nylon taffeta (basis weight 60 g / m 2 ) are shown in Tables 5 and 8. The results of treating a blended fiber of polyester fiber / rayon (mixing ratio 65 / 35) (basis weight 200 g / m 2 ) are shown in Tables 6 and 7. The results of treating 100% polyester taffeta (basis weight 50 g / m 2 ) are shown in Tables 9 and 10.
