Below, embodiments of the present invention are elaborated.Moreover about same content, suitable for fear of repeating loaded down with trivial details situation description thereof is omitted.
< embodiment 1: fiber for artificial hair >
The flexural rigidity through KES method of the fiber for artificial hair the present invention relates to, appropriateness large can be supplemented the rigidity that makes to keep gear waveform, therefore having the tendency that be difficult to crispatura processing and quality improve.On the other hand, the side that appropriateness is little, because the low rigidity of appropriateness has the tendency that sense of touch improves.Therefore, the flexural rigidity through KES method of the fiber for artificial hair that present embodiment relates to, is preferably 0.001～0.01gfcm
2, more preferably 0.002～0.008gfcm
2.
At this moment, can be confirmed curly hair uniformity and the sense of touch excellence of above-mentioned fiber for artificial hair by embodiment described later.Therefore, above-mentioned fiber for artificial hair, is particularly suitable for curling fiber for artificial hair and the purposes or the curly hair type hair ornament that use.Moreover, curly hair type hair ornament in this manual, comprise sale again the circulation stage possess curly hair type shape hair ornament or as being applicable to giving curling commodity and the hair ornament selling or circulate.
In addition above-mentioned fiber for artificial hair also can be the fiber with one deck structure.At this moment, fibrous inside because of layer, to form the strain producing less, improve the quality of curly hair uniformity etc.Moreover, in this manual, there is the fiber of one deck structure, in the time observing the section at any place of fiber with scanning electron microscope, if do not have the fiber of the conglobate boundary line of shape to be just not particularly limited.For example, by fibre cutting 10 places, and while observing the cross section of fiber with scanning electron microscope, among this section 1 does not have in the situation of the conglobate boundary line of shape, this fiber be just included in above-mentioned enter in the fiber of one deck structure.In addition there is the fiber of above-mentioned one deck structure,, just can produce by the production method of typical fiber for artificial hair for fiber multifunction is carried out to melt-spun in the mode that forms more than 2 layers at fibrous inside so long as not during fabrication.For example, the production method that can record by embodiment 1 described later is produced.But the above-mentioned fiber with one deck structure, also comprises such fiber,, in the operation of melt-spun, after nozzle spues fiber, to the result of certain film of fibre applicator, form the fiber of overlay at fiber surface.This is because before in general melt-spun, fiber spues from nozzle, first forms the main bone of fiber, and the difficult quality of fiber declines to a great extent because of the coating of film thereafter.
The said KES method of this description is the abbreviation of river end evaluation system (Kawabata Evaluation System), as at river end Ji Xiongzhu, fibre machines association magazine (fiber engineering), vol.26, No.10, P721-P728 (1973) record like that, the repulsive force of the each curvature during with the flexural property measuring machine (KES-FB2-SH processed of KATO TECH Corporation) of the KES fibrous structure thing of having measured bending.And the mensuration in present embodiment is the mean value of the repulsive force to 1 fiber mensuration between curvature 0.5 to 1.5.By measuring the repulsive force of 1 fiber, determine the rigidity of fibre bundle.

In melt-spun operation, can use single axle extruding machine, counter rotation twin screw extruder, conical double screw extruder etc., specifically, use these extruders 160～190 ℃ of mold temperatures, more preferably spherolite compound to resin combination (ペ レ Star ト コ Application パ ウ Application De) etc. carries out melt-spun at 165～185 ℃.Here, the side that mold temperature appropriateness is large, can provide and have flexural rigidity appropriate hardness, modest size fiber.On the other hand, the side that mold temperature appropriateness is little, can provide and have flexural rigidity natural flexibility, appropriateness fiber.
The extruder of melt-spun operation, the preferably conical extruder of the single axle extruding machine of bore 35～85mm or bore 35～50mm.If the little extrusion capacity of bore just less, nozzle exit pressure reduces, or the rate of outflow of undrawn yarn is slack-off and have the tendency of the backrush of being easy to, and is therefore preferred.
With described embodiment similarly, the single fiber fineness of the fiber for artificial hair in present embodiment is preferably 20～100 dtexs, more preferably 35～80 dtexs.In order to accomplish this single fiber fineness, preferably making the very thin degree of melt-spun operation fiber (not drawing of fiber) is afterwards below 300 dtexs.If the very thin degree of drawing of fiber is not little, for the fiber for artificial hair that obtains thin very thin degree reduces stretching ratio, this is because the fiber for artificial hair after stretch processing is difficult to produce gloss, so have the cause of the tendency that easily maintains gloss medium～70% glossy condition.
The cross-sectional area of the nozzle that melt-spun uses is not particularly limited, and also can be 0.1～2mm.In addition if be considered as the quality aspect of curly hair characteristic that artificial hair uses etc., be preferably 0.5mm from the cross-sectional area of 1 nozzle bore,
2following nozzle melting/outflow.If the cross-sectional area of 1 nozzle bore is less than 0.5mm
2, the undrawn yarn of thin very thin degree or be suppressed to lowlyer as the tension force that prolongs heated filament, overstrain is reduced, and the difficult quality of curly hair retentivity etc. declines.
In the time of melt-spun, nozzle exit pressure is preferably below 50MPa.This is because following cause: if nozzle exit pressure appropriateness is little, be added to the load reduction of the thrust portion of extruder, have and be difficult to produce bad tendency at extruder, and there is the tendency that is difficult to produce from the connecting portion of loop line head (turn head), mould (die) etc. resin leakage.
The mould using in melt-spun, can adopt the freely spinning mould of a kind of above nozzle form of the group of circle, cocoon shape, Y shape, H shape and X-shaped composition of choosing.Because these moulds do not have complicated shape, so the easy such fiber of mfg. moulding die.And, adopt the fiber of these Mold Makings easily to keep shape, be also easier in addition processing.
Under the atmosphere of 90～120 ℃ of stretch processing temperature, with the stretching process of the fiber of stretching ratio 200～400% stretching melt-spuns, the fiber that can obtain melt-spun is the fiber of the thin very thin degree below 100 dtexs.
If stretch processing temperature is too low, there is the strength decreased of fiber and the tendency of fracture of wire easily occurs, if the sense of touch of the too high fiber obtaining to some extent becomes the tendency of the such smooth sense of touch of plastics, therefore needing is 90～120 ℃.Stretching ratio has the large side's appropriateness of appropriateness and produces the tendency of the intensity performance of fiber, and the little side of appropriateness is difficult to occur the tendency of fracture of wire while having stretch processing, need to be 200～400%.
Adopt the reason of hot loose operation to be to reduce the percent thermal shrinkage of the fiber for artificial hair obtaining in present embodiment.Even the loose processing of heat after stretch processing, carry out, also can be on temporary transient volume after the compartment time carry out.
Temperature under the air atmosphere of the loose operation of heat, if there is appropriate size, has the reduction effect of percent thermal shrinkage to be difficult to diminish, and has silk and is difficult to pine, the tendency of easily manufacturing.In addition, a very not large side, has the tendency that fiber easily bears shrinkage stress, there will not be in the mill fracture of wire or variable color.Therefore,, in the manufacture method of the fiber for artificial hair forming take vinyl chloride resin as raw material, be preferably 110～140 ℃.By the loose operation of this heat, can make fiber total length become the length of 60～95% after stretching process.
The above-mentioned operation of crispaturaing is the operation for give relief intensity (wave-like) to fiber for artificial hair.
If crispatura, braiding property is good by force, but card while having combing is sent out the tendency of deterioration.On the other hand, if a little less than crispaturaing card when combing send out well, but the tendency that has braiding property to worsen.Need to seek this balance.
This operation of crispaturaing has gear crimping processing, chemical fibre wool (ウ mono-リ mono-) processing method, preferably gear crimping processing.
This gear crimping processing is the method for implementing to crispatura between the gear of fibre bundle by the high temperature of 2 engagements by making.
In gear crimping processing, can control by the degree of depth of the groove of control gear waveform, gear surface temperature, process velocity the wave-like of fiber for artificial hair.The tendency that appropriateness is strong, can give to fiber for artificial hair appropriate relief intensity of crispaturaing when the degree of depth of the groove of gear waveform has modest size.In addition, the side that the degree of depth of the groove of gear waveform appropriateness is little, has the card of crispaturaing and sends out the tendency that degree can relief intensity that is excessively strong and fiber for artificial hair diminish yet, and is therefore preferably 0.2mm～6mm, more preferably 0.5mm～5mm.
The surface temperature of gear has the tendency that the large side of appropriateness crispaturas appropriateness by force and easily gives relief intensity to fiber for artificial hair.The surface temperature of gear has the little side of appropriateness, and crispatura can be excessively not strong, and therefore the tendency that the relief intensity of fiber for artificial hair diminishes is preferably 30～100 ℃, more preferably 40～80 ℃.
The process velocity of gear, has the tendency that the relief intensity of the large side's fiber for artificial hair of appropriateness diminishes.In addition, the process velocity of gear, have appropriateness hour crispatura appropriate grow, easily give relief intensity to fiber for artificial hair tendency, be therefore preferably 0.5～10m/ minute, more preferably 1.0～8.0m/ minute.
Fiber for artificial hair by before gear is implemented to preheating, so just can not be overheated suddenly, can obtain stable productivity ratio, uniform wave-like.
Gear crimping adds the total very thin degree of the fibre bundle in man-hour, have appropriateness a large side be difficult to crispatura processing in there is the tendency that fracture of wire, productivity ratio improve.In addition, gear crimping adds the total very thin degree of the fibre bundle in man-hour, has the little side of appropriateness and easily obtains the tendency of uniform wave-like, is therefore preferably 100,000～200 specially very much, and more preferably 500,000～150 is special very much.
In addition, gear crimping processing is shorter because add the time of thermal fiber, thus less from the evaporation of the moisture of the fibrous inside in processing of crispaturaing, and fracture of wire or damage less.In fiber for artificial hair, moisture is to give the important key element of damp that approaches natural hair.Thereby, through the fiber for artificial hair of gear crimping processing and manufacturing, deserve to be called quality and productivity ratio good.In addition, gear crimping processing does not need long work, does not need complicated device or complicated operation, is therefore the processing method that workability, productivity ratio or precision are good.And, controlled also high, be therefore the processing method being applicable to desirable wave-like on fabric strip.
