Detailed Description
Hereinafter, embodiments of the present invention will be described.
The fiber for artificial hair of the present embodiment comprises 5 to 40 parts by mass of a bromine-based flame retardant and 0.01 to 10 parts by mass of a processed pigment per 100 parts by mass of polyamide, wherein the processed pigment comprises a colorant and a dispersant, the dispersant is 20 to 80% by mass when the total amount of the colorant and the dispersant is 100% by mass, and the dispersant is one or more of a montanic acid metal salt, a montanic acid wax, a polyethylene wax, and a fluorine wax. The fiber for artificial hair can be produced by melt spinning the resin composition of these compositions.
Hereinafter, each constituent element will be described in detail.
< polyamides >
The polyamide preferably contains an aliphatic polyamide, may be composed of an aliphatic polyamide alone, or may contain an aliphatic polyamide and a semi-aromatic polyamide.
The aliphatic polyamide is a polyamide having no aromatic ring, and examples of the aliphatic polyamide include n-nylon obtained by ring-opening polymerization of lactam and n, m-nylon obtained by copolycondensation of aliphatic diamine and aliphatic dicarboxylic acid. Examples of the aliphatic polyamide include polyamide 6 and polyamide 66. Polyamide 66 is preferred from the viewpoint of heat resistance.
The semi-aromatic polyamide has a skeleton obtained by polycondensation of an aliphatic diamine and an aromatic dicarboxylic acid. Examples of the semi-aromatic polyamide include polyamide 6T, polyamide 9T, and polyamide 10T, and modified polyamide 6T, modified polyamide 9T, and modified polyamide 10T obtained by copolymerizing a modifying monomer in addition to these polyamides.
The weight average molecular weight (Mw) of the polyamide is, for example, 6.5 to 15 ten thousand. When Mw is 6.5 ten thousand or more, the drip resistance becomes particularly good, and when Mw exceeds 15 ten thousand, the melt viscosity of the material increases and the processability at the time of fiberization is poor, so that 15 ten thousand or less is preferable. In view of the balance between the drip resistance and the processability, the Mw is more preferably from 7 to 12 ten thousand.
< bromine-containing flame retardant >
The amount of the bromine-based flame retardant added is 5 to 40 parts by mass, preferably 10 to 30 parts by mass, based on 100 parts by mass of the polyamide. This is because the effect of imparting the drip resistance and the processability are well balanced within the above range.
Examples of the bromine-based flame retardant include brominated phenol condensates, brominated polystyrene resins, brominated benzyl acrylate flame retardants, brominated epoxy resins, brominated phenoxy resins, brominated polycarbonate resins, and bromine-containing triazine compounds. In view of the balance of drip resistance, processability, transparency (clarity) of the base yarn and the like, a brominated epoxy resin or a brominated phenoxy resin having a structural formula shown in the following (1) is preferably included.
[ CHEM 1 ]
< processing pigment >
The process pigment includes a colorant and a dispersant. Can be produced by mixing a colorant and a dispersant. The addition amount of the processing pigment is 0.01 to 10 parts by mass, preferably 0.1 to 5 parts by mass, relative to 100 parts by mass of the polyamide. More preferably 0.2 to 2 parts by mass. Within the above range, the balance between the coloring property and the processability is good.
The colorant is a pigment, a dye or the like, and by incorporating the colorant, a pre-colored fiber (so-called dyed fiber) can be obtained.
The colorant may be a black-based colorant, a red-based colorant, a yellow-based colorant, a violet-based colorant, or the like, and 1 or more of these colorants are used.
Examples of the Black-based colorant include Pigment Black 7 and Solvent Black 7, and Pigment Black 7 is preferable from the viewpoint of flame retardancy.
Examples of the Red-based coloring agent include Pigment Red 149, Pigment Red 177, Solvent Red 179 and the like, and Pigment Red 149 is preferable from the viewpoint of flame retardancy.
Examples of the Yellow-based colorant include Pigment Yellow 147, Solvent Yellow 163, Solvent Yellow 21, and Pigment Yellow 184, and Pigment Yellow 147 and Solvent Yellow 163 are preferable from the viewpoint of flame retardancy.
Examples of the Violet colorant include Pigment Violet 19 and Pigment Violet 29, and Pigment Violet 19 is preferable from the viewpoint of flame retardancy.
The dispersant has a function of improving the dispersibility of the colorant in the polyamide. The dispersant is at least one of metal montanate, montanic acid wax, polyethylene wax, and fluorine wax. Metal salts of montanic acid are preferred. Since the snap-off resistance is particularly good in this case. Examples of the montanic acid metal salt include calcium montanate, zinc montanate, and sodium montanate. Calcium montanate is particularly preferred as the dispersant. This is because the occurrence of color unevenness is particularly suppressed.
When the total amount of the colorant and the dispersant is 100% by mass, the dispersant is 20 to 80% by mass, preferably 30 to 70% by mass. When the dispersant is too small, the durability is deteriorated, and when the dispersant is too large, the fracture resistance is deteriorated.
< other additives >
The resin composition constituting the fiber for artificial hair may further contain additives such as flame retardant aids, organic fine particles, heat-resistant agents, light stabilizers, fluorescent agents, antioxidants, antistatic agents, plasticizers, lubricants and the like as required.
< production Process >
An example of the process for producing the artificial hair fiber will be described below.
The method for producing a fiber for artificial hair according to an embodiment of the present invention includes a melt spinning step, a drawing step, and a heat treatment step.
The respective steps will be described in detail below.
(melt spinning Process)
In the melt spinning step, the resin composition is melt spun to produce an undrawn yarn. Specifically, the resin composition is first melt-kneaded. Various ordinary kneading machines can be used as a device for melt kneading. Examples of the melting and kneading apparatus include a single screw extruder, a twin screw extruder, a roll, a Banbury mixer, and a kneader. Among them, a twin-screw extruder is preferably used from the viewpoint of adjustment of the kneading degree and ease of operation. The fiber for artificial hair can be produced by melt-spinning the polyamide at an appropriate temperature by a usual melt-spinning method.
Melt spinning is performed by setting the temperature of a melt spinning device such as an extruder, a spinneret, and a gear pump as needed to 270 to 310 ℃, cooling the melt spinning device in a water tank containing cooling water, and controlling the fineness of the melt spun yarn and adjusting the drawing speed to obtain undrawn yarn. The temperature of the melt spinning apparatus can be adjusted as appropriate depending on the composition of the resin composition. In addition, not only the spinning can be cooled by using a water tank, but also the spinning can be cooled by using a cold wind method or the like. The temperature of the cooling water tank, the temperature of the cold air, the cooling time, and the drawing speed can be appropriately adjusted according to the discharge amount and the number of holes of the spinneret.
The single-fiber-length of the fiber for artificial hair according to the present embodiment is preferably 20 to 100 dtex, and more preferably 35 to 80 dtex. In order to obtain such a single fineness, it is preferable that the fineness of the fiber (undrawn yarn) after the melt spinning step is 300 dtex or less. As the fineness of the undrawn yarn is smaller, a fine fineness artificial hair fiber can be obtained even with a small draw ratio, and the artificial hair fiber after the drawing treatment tends to be less likely to be glossy, and thus tends to maintain a semi-glossy to seven-glossy state.
The cross-sectional area of the nozzle used for melt spinning is not particularly limited, but may be 0.1 to 2 mm. Considering the quality such as curling property for artificial hair, the cross-sectional area of each nozzle hole is preferably 0.5mm2The following nozzles melt and flow out. For example, the cross-sectional area ratio of each nozzle hole is 0.5mm2When the amount is small, the tension required for forming a fine-denier undrawn yarn or hot-drawn yarn is suppressed to be low, and the residual strain is reduced, whereby the quality such as the curl retention property is not easily deteriorated.
In melt spinning, the nozzle pressure is preferably 50MPa or less. The load applied to the thrust portion of the extruder is low, and thus the extruder is less likely to be broken down, and resin leakage from the connecting portion such as a rotor or a die is less likely to occur.
The spinneret used for melt spinning may have a spinning die having 1 or more nozzle shapes selected from a circular shape, a cocoon shape, a Y shape, an H shape, and an X shape. Since these spinnerets do not have a complicated shape, they can be easily formed into fibers in the shape of a die. Further, the fibers produced by using these spinnerets are easy to hold in shape and easy to process.
(stretching Process)
In the drawing step, the obtained undrawn yarn is drawn by 150 to 500% to produce a drawn yarn. By drawing in this manner, drawn yarns having a fine fineness of 100 dtex or less can be obtained, and the tensile strength of the fibers can be improved. The drawing treatment is either a 2-step method in which an undrawn yarn is wound around a bobbin and then drawn by a step different from the melt spinning step, or a direct spin-drawing method in which the undrawn yarn is directly drawn from the melt spinning step without being wound around the bobbin. The stretching treatment is performed by a 1-stage stretching method in which stretching is performed at once at a stretching ratio, or a multistage stretching method in which stretching is performed at a stretching ratio by 2 or more times. As a heating means for the thermal stretching treatment, a heating roller, a hot plate, a steam jet device, a warm water tank, or the like can be used, or these may be appropriately used in combination. The stretch ratio is preferably 200 to 400%. If the draw ratio is appropriately large, the strength development (strength development) of the fiber tends to be easily caused, and if the draw ratio is appropriately small, the fiber tends to be hard to break during the drawing process.
The temperature during the stretching treatment is preferably 90 to 120 ℃. If the stretching treatment temperature is too low, the lightness of the fiber becomes low and at the same time, the yarn breakage easily occurs, and if it is too high, the touch of the fiber produced tends to have a smooth touch as a plastic.
(Heat treatment Process)
In the heat treatment step, the drawn wire is subjected to heat treatment at a heat treatment temperature of 155 ℃ or higher. By this heat treatment, the heat shrinkage of the drawn yarn can be reduced. The heat treatment may be performed continuously after the stretching treatment, or may be performed after the winding treatment at a time interval. The heat treatment temperature is preferably 160 ℃ or higher, more preferably 170 ℃ or higher, and still more preferably 180 ℃ or higher. The upper limit of the heat treatment temperature is not particularly limited, and is, for example, 220 ℃.
[ examples ] A method for producing a compound
Examples of artificial hair fibers according to the invention are explained in more detail using tables and comparative examples. Next, the present invention will be explained in more detail based on examples, but the present invention is not limited thereto.
The polyamide, flame retardant and processing pigment dried to a water absorption of less than 1000ppm were mixed in the blending ratios of examples and comparative examples shown in tables 1 to 4. The resulting mixture was kneaded using a twin-screw extruder having a diameter of 30mm to obtain a raw material pellet for spinning.
Subsequently, the resulting fibers were dehydrated and dried to obtain pellets having a water absorption of 1000ppm or less, and then spun by a uniaxial melt spinning machine having a diameter of 40mm, and the molten resin discharged from the die having a hole diameter of 0.5 mm/barrel was cooled in a water tank having a temperature of approximately 30 ℃ to prepare an undrawn yarn having a predetermined fineness by adjusting the discharge amount and the take-up speed. The melt spinning machine comprises a screw, a wire mesh filter, and a die in this order, and the particulate matter is heated and melted by the screw to form a molten resin composition, and the molten resin composition is filtered by the filter and then left to stand from the die. The set temperature of the mold was 290 ℃.
The obtained undrawn yarn was drawn at 100 ℃ and then annealed at 150 to 200 ℃ to obtain a fiber for artificial hair of a predetermined size. The stretching ratio is 3 times, and the relaxation rate during annealing is 0.5-3%. The relaxation rate at the time of annealing is a value calculated from (the rotation speed of the wind-up roller during annealing)/(the rotation speed of the paper-discharge roller during annealing).
The obtained artificial hair fiber was evaluated for color unevenness, transparency (clarity), flame retardancy, breaking resistance, and long-lasting property according to the evaluation method and criteria described below. The results are shown in tables 1 to 4.
