The specific embodiment
Below, for the present invention, be elaborated, but the present invention is not limited to each embodiment shown below.
The invention provides the there is excellent crimpiness fiber for artificial hair of (formative nature, shape stability).The not special restriction of fiber for artificial hair, such as can be by the resulting synthetic fibers of spinning resin combination or making inorganic agent etc. be attached to the fibrous matter formed on synthetic fibers.
Can form processing by the processor of the producer of fiber for artificial hair, hair product or any one of ultimate consumer of buying hair product.For example, fiber for artificial hair or the producer of hair product apply the shaping processing of curling grade before selling market to fiber for artificial hair.Before fiber for artificial hair is processed into to hair product, the processing of being processed into hair product midway or any one stage of being processed into after hair product can form processing.In addition, the processing that is shaped is not defined as curling (wave), comprises the situation that wave is processed into to straight (straight hair) yet.
Manufacturing process has no particular limits, and the method for heating apparatus contact (pressing) fiber for artificial hair that makes curler etc., the method be exposed to hot blast under the state that fiber for artificial hair is wrapped with to volume core (metal-made cylinder etc.) in is arranged or heat method etc. of its volume core itself.But, generally speaking, be to use the method that fiber for artificial hair is wrapped with to the volume core and places it in heating in heating furnace (baking oven).
The not special restriction of the heating-up temperature of shaping use (forming temperature), can carry out suitable change according to the raw material of fiber for artificial hair etc.But, generally speaking, the scope that this heating-up temperature is 90～150 ℃ (forming temperature zone).
Fig. 1 is the ideograph of the viscoelastic properties for fiber for artificial hair is described.Synthetic fibers can make storage elastic modulus E ' and loss elastic modulus E by heating " descend simultaneously, its rate of change is larger, and the distortion of curling grade is just easier.Therefore, when carrying out the forming temperature zone (the curling temperature province of the baking oven of Fig. 1) of curling grade, rate of change the greater is applicable to fiber for artificial hair.
The change curve of the elastic modelling quantity that the symbol c of Fig. 1 is commercially available heat-resisting artificial hair (E ', E ").Heat-resisting artificial hair is because having heat resistance, and therefore the variation of the elastic modelling quantity under forming temperature (E ', E ") is little, and the formability of curling grade is poor.As shown in symbol a, the b of Fig. 1, when the variation of the elastic modelling quantity under forming temperature (E ', E ") is larger, easily distortion under forming temperature, formability is better.
The variation of the elastic modelling quantity under forming temperature (E ', E ") can be adjusted by changing as the composition of the resin combination of fiber for artificial hair raw material.For example, if take the lower thermoplastic resin of glass transformation temperature is main material, can makes elastic modelling quantity under forming temperature (E ', E ") significantly change, but can make its heat resistance deteriorated.
After shaping processing (city after sale), the ultimate consumer carries out the processing (postforming) of hair product sometimes according to individual hobby.Mostly use commercially available heating apparatus (curler etc.) in postforming, its heating-up temperature is various, be 60～240 ℃.But, because the consumer likes powerful formative nature at short notice, therefore, have and use the pre-sales shaping than city to process the more tendency of high temperature (180～240 ℃, the postforming temperature province).
As shown in curve b, even the rate of change under the forming temperature zone is large, if but arrive postforming temperature province (the curling temperature province of the flatiron of Fig. 1) and start before to have the melting deformation of fiber, can cannot stand the high temperature process of curler, cause sometimes that fiber significantly shrinks, damage of fiber, fracture etc.
Therefore, desirable: as shown in curve a, can melting and larger with the rate of change under the postforming temperature province in the forming temperature zone before arriving the postforming temperature province.Yet the variation of elastic modelling quantity (E ', E ") is also larger when melting, a of Fig. 1, c melting under the postforming temperature province, and b melting before arriving the postforming temperature province.On general the use, can not heat fiber for artificial hair under the high temperature in rear heating-up temperature zone, therefore, if rate of change is larger under the postforming temperature province, as shown in a, c, also it doesn't matter to cause melting under this zone.
The zone that the forming temperature often used in the artificial hair field is 90～150 ℃, and the zone that the postforming temperature of consumer's hobby is 180～240 ℃.That is, elastic modelling quantity has larger variation person for good in these zones.
Though the variation of elastic modelling quantity is better to crimpiness more greatly, excessive variation means the contraction of fiber.For example, with respect to temperature (℃) storage elastic modulus E ' in, storage elastic modulus E ' in the time of 90 ℃ 90 and the ratio E ' 90/E ' 150 of storage elastic modulus E ' 150 in the time of 150 ℃ take 3～20 as good, more preferably 4～10.
Once E ' 90/E ' 150 is less than 3, the variation of the elastic modelling quantity when forming temperature zone (90～150 ℃) will be less, and therefore, curling shaping is difficulty comparatively, causes crimpiness bad.On the other hand, E ' 90/E ' is once 150 surpass 20, and fiber can shrink, thereby causes crimpiness bad.In addition, it would be desirable, E ' 90/E ' 150 is 4～10 o'clock, and fiber can not shrink, and can realize excellent crimpiness.
In addition, consider postforming, though heat resistance the higher person is good, once heat resistance is too high, can't carry out postforming (pressing curling).Therefore, it is desirable to, the deformation temperature of the vitreousness disintegration of crystallization is enclosed should be in the scope of 180～240 ℃.As for deformation temperature, for example, in the tangent line of storage elastic modulus curve, the tangent line that is certain zone (vitreousness zone) by storage elastic modulus, with by temperature higher than the rate of change of this zone and storage elastic modulus the temperature for the position of intersecting point of the tangent line of the highest transition region (or the rate of change of storage elastic modulus is maximum transition point), be considered to this deformation temperature.
By suitably adjusting creating conditions and the composition of raw material of fiber for example, can produce and meet said temperature, viscoelastic fiber for artificial hair.
<resin combination >
Resin combination is to using thermoplastic resin as principal component (more than content 50 quality %), optionally can comprise the additive of fire retardant, filler, colouring agent, antioxidant etc.Viscoplasticity (E ', E " etc.) can be adjusted according to the blending ratio of the thermoplastic resin such as two or more or the mixed proportion of thermoplastic resin and additive (fire retardant, filler etc.).Especially, can, by sneaking into the two or more thermoplastic resins with different glass transition temperature, can obtain being with the postforming temperature province fiber for artificial hair that Flexible change is large in the forming temperature zone.
Except said method, also can create conditions to adjust viscoplasticity by what adjust fiber.For example, can adjust viscoplasticity by suitably changing tractive multiplying power and stretching ratio.In addition, so-called tractive multiplying power, be that resin out is to the multiplying power be stretched till cooling from nozzle bore, and so-called stretching ratio is the multiplying power (multiplying power during stretching) that undrawn yarn is stretched.
Below for tractive multiplying power and stretching ratio, be elaborated.In the manufacturing process of fiber for artificial hair, the composition that will contain thermoplastic resin carries out heating and melting and from the nozzle bore ejection, optionally make it by cartridge heater after the cooling undrawn yarn that obtains.After the nozzle bore ejection, become undrawn yarn until cooling, the multiplying power be stretched is the tractive multiplying power.In addition, the multiplying power be stretched can be by the draw rate of undrawn yarn and recently calculating from the spouting velocity of nozzle.
Then carry out the stretch processing of undrawn yarn, to improve the hot strength of fiber.Stretch processing is by still cooling undrawn yarn, with heating and melting temperature low temperature when spinning heat the operation of on one side carrying out stretching on one side.Undrawn yarn (before adding hot-stretch) is until the multiplying power that stretch processing is stretched is stretching ratio.The multiplying power that is stretched now can be calculated by the ratio of the speed of rolling of silk after the development rate of undrawn yarn and stretch processing.

By the embodiment 1～4 that the ratio (tractive multiplying power/stretching ratio) of tractive multiplying power D1 and stretching ratio D2 is set as 1.5～14.0, the ratio of storage elastic modulus (E ' 90/E ' 150) is 3～20, be not baking oven crimpiness, processability, also comparatively excellent on intensity.Wherein, the embodiment 1,4 that the ratio of storage elastic modulus (E ' 90/E ' 150) is 4～10, give especially good results in the baking oven crimpiness.
The ratio (D1/D2) of drawing-off multiplying power D1 and stretching ratio D2 is once be less than 1.5, and the undrawn yarn that too stretches when stretching can cause easily fracture of silk, causes processability deteriorated.On the other hand, the ratio (D1/D2) of tractive multiplying power D1 and stretching ratio D2, once surpass 14.0, can't fully carry out stretch processing (stretching of undrawn yarn), causes hot strength to diminish.
In embodiment 5, the ratio of storage elastic modulus (E ' 90/E ' 150) is 3.6, although baking oven crimpiness and processability are not good but good, even in this scope, but has the characteristic of the sufficient scope of application.In addition, the tractive multiplying power D1 of embodiment 5 is 1.5 with the ratio (D1/D2) of stretching ratio D2, though the ratio of this tractive multiplying power D1 and stretching ratio D2 at 1.5 o'clock, processability also belongs to good scope, but has the characteristic of the scope of application.
In embodiment 6, the ratio of storage elastic modulus (E ' 90/E ' 150) is 18.5, although baking oven crimpiness transitivity (hot strength) is not good but good, even in this scope, but has the characteristic of the sufficient scope of application.In addition, the drawing-off multiplying power D1 of embodiment 6 is 12 with the ratio (D1/D2) of stretching ratio D2, though the ratio of this tractive multiplying power D1 and stretching ratio D2 at 12 o'clock, hot strength (physical property) also belongs to good scope, but has the characteristic of the scope of application.
With respect to this, in the ratio of storage elastic modulus (E ' 90/E ' 150) is less than 3 comparative example 1, its baking oven crimpiness is poor, and surpasses 20 comparative example 2 at the ratio of storage elastic modulus (E ' 90/E ' 150), just the baking oven crimpiness is not inadequate, and intensity is also bad.
The measurement result of the dynamic viscoelastic of embodiment 1 is shown in Fig. 2, and the measurement result of the dynamic viscoelastic of comparative example 1 is shown in Fig. 3.By Fig. 3, can be learnt, even the fiber for artificial hair of comparative example 1 can melting under the high temperature of 240 ℃ yet, keeping storage elastic modulus E ', heat resistance is very high.But, therefore because heat resistance is too high, not only in forming temperature zone (90～150 ℃), also can melting in postforming temperature province (180～240 ℃), make storage elastic modulus E ', loss elastic modulus E " variation less.With respect to this, no matter the rate of change of the fiber for artificial hair of embodiment 1 in forming temperature zone or postforming temperature province is all larger, formability is very high.
Fig. 2,3 symbol M 1 are in the curve of the storage elastic modulus E ' with respect to temperature, mean that storage elastic modulus E ' is for tangent line certain, the zone (vitreousness zone) that is vitreousness by crystalline state, with the symbol M 2 of figure, be illustrated in temperature higher than the high temperature side in vitreousness zone, the tangent line that is the highest transition region by rate of change.As for the curve of this storage elastic modulus E ', at the tangent line M1 by the vitreousness zone and the tangent line M2 by transition region, on crossing intersection point P, the crystalline state disintegration, start melting.From above-mentioned Fig. 2, the temperature coordinate of the intersection point P of the fiber for artificial hair of embodiment 1, in the scope of 180～240 ℃, can be used commercially available curler (heating-up temperature is below 240 ℃) to be processed.With respect to this, the temperature coordinate of the intersection point P of comparative example 1, surpassing on the position of 240 ℃, is difficult to use commercially available curler to be processed.Utilizability on industry
The not special restriction of the purposes of fiber for artificial hair of the present invention, the hair of can be used for hair net, sending out sheet, pigtail, sending and receiving etc. is decorated or the various hair products such as the hair of doll (doll hair).
