The specific embodiment
Is that following specifying carried out at the center for the present invention in particularly preferred mode.
Toy moppet hair fiber of the present invention is characterized in that containing the specific permalon of following explanation.
The weight average molecular weight of permalon is 5 * 10
4～8 * 10
4Be preferably 5.5 * 10
4More than, 7.5 * 10
4Below, more preferably 6 * 10
4More than, 7 * 10
4Below.This scope is lower for the weight average molecular weight of the permalon of general use.But, as long as in this scope, just can keep as the necessary intensity of toy moppet hair, can improve productivity simultaneously.From the angle of intensity, be 5 * 10
4More than.If in this scope, when planting to good doll heads mao, the anti-depilation in the time of just can obtaining planting mao processability and carding.And,, be 8 * 10 from productive angle
4Below.Though reason is still indeterminate, if in this scope, during spinning, in the inner obstruction that is difficult for producing thermal decomposition, spinneret orifice of extruder, it is elongated that spinneret orifice need not be replaced the time that can use continuously.
Here the replacement of said spinneret orifice is meant, stops the operation that the spinning operation replaces to other spinneret orifice.Because spinneret orifice needs the time when precision is cleaned, therefore to prepare out cleaned spinneret orifice in advance.When the thermal decomposition by permalon causes the obstruction of bubble (hydrochloric acid gas) generation and spinneret orifice, in the cleaning of carrying out extruder inside, replace.The frequency that spinneret orifice is replaced, because productivity is had considerable influence, so the long continuous service time of spinneret orifice (begin to stopping from spinning, but the time of not replacing the spinneret orifice continuous spinning) be very important.
For the weight average molecular weight with permalon is adjusted to above-mentioned scope, can use the more than ever before consumption of polymerization initiator, perhaps polymerization temperature is set in than higher in the past temperature, perhaps share both etc. method.
The molecular weight that permalon contains is 1 * 10
4Following low molecular weight compositions, in the total amount of permalon in the scope more than 3%, below 10%.Here molecular weight is 1 * 10
4The ratio of following low molecular weight compositions is to use to obtain GPC figure by gel permeation chromatography and represent with following formula.
(molecular weight is 1 * 10
4The ratio of following low molecular weight compositions)=(molecular weight is 1 * 10
4The following shared area of low molecular weight compositions)/(gross area at peak) * 100
Fig. 1 represents 1 example of molecular weight distribution.Among Fig. 1, the area of the scope that oblique line is represented means that molecular weight is 1 * 10
4The following shared area of low molecular weight compositions.The area that curve and transverse axis surrounded on the GPC figure is the gross area at peak.
Molecular weight is 1 * 10 in the permalon
4Following low molecular weight compositions is more than 3%.Though reason is not clear, when this scope, is difficult to produce the obstruction of bubble (hydrochloric acid gas) and spinneret orifice during spinning, spinneret orifice is elongated continuous service time.And molecular weight is 1 * 10
4Following low molecular weight compositions shows the effect that substitutes various additives.In order to bring into play this effect, low molecular weight compositions is to be essential more than 3%.From the angle of intensity is below 10%.As in this scope, can guarantee necessary strength for toy moppet hair, when doll heads is planted mao plant mao processability and carding the time anti-depilation become good.Be preferably more than 3%, below 9%, more preferably more than 4%, below 8%, more preferably more than 5%, below 7%.
In order to be 1 * 10 with molecular weight in the permalon
4The content of following low molecular weight compositions is adjusted to above-mentioned scope, can suitably set aggregate rate.This be since from the polymerization initial stage to mid-term, i.e. generate more high molecular weight polymers in the stage that aggregate rate is lower, in polymerization latter stage, promptly the higher stage of aggregate rate generates more low-molecular-weight polymer.Here aggregate rate is meant, the whole polymer that use with respect to polymerization, the weight rate of the polymer that is generated by polymerisation.And, can use the polymerization initiator of more amount, also can change the kind of polymerization initiator.In addition, also can share.
Kind time-like changing polymerization initiator not only can use di-isopropyl peroxydicarbonate, dilauroyl peroxide etc., can also use more special polymerization initiators such as t-butylperoxy pivarate.
The molecular weight distribution of permalon as long as satisfy above-mentioned condition, can be a Unimodal Distribution, also can be the bimodal distribution of the higher composition of lower composition of molecular weight and molecular weight, also can be the set of multimodal.Be preferably unimodal from the angle of property easy to manufacture.Decentralization (Mw/Mn) as the ratio of the weight average molecular weight (Mw) of permalon and number-average molecular weight (Mn) is preferably 2～5 scope, more preferably 2.1～4 scope, more preferably 2.2～3 scope.Molecular weight distribution shown in Figure 1 is a preferred example.
