Description
Technical field
The present invention relates to the technology of melt spinning device.Be to relate to the technology of the melt spinning device that can manufacture the silk thread that total fiber number and filament number are large and high-quality more in detail.
Background technology
The melt spinning device of the thermoplasticity polymers manufacturing silk thread that in the past, we had known by melting.Melt spinning device by melting thermoplasticity polymer offer filament spinning component, from the spinning head of filament spinning component, many filaments (filament group (Off ィ ラ メ Application ト group)) are spun to below.Below spinning head, dispose cooling device, cooling curing, from the spun filament group of spinning head, is then implemented the processing of regulation and is manufactured silk thread or staple fibre.
Silk thread or the staple fibre in melt spinning device, manufactured have many types.For example, be useful on the silk thread of dress material etc., for the silk thread of industrial materials etc. or filament group is prescinded to staple fibre of manufacture etc.In this manual, so-called silk thread means from the silk thread of long long filament group (long fiber) generation.
In the silk thread of being manufactured by melt spinning device, for example dress material requires the high uniformity with silk thread, but staple fibre and industrial materials in most cases do not require the so high uniformity of silk thread for dress material with silk thread.
In the cooling device of melt spinning device, the operation of cooling curing filament group is extremely important manufacturing on the high-quality silk thread that the uniformity is high.For example, if the inner side of filament group and outside exist temperature difference in refrigerating work procedure, cooling curing spun filament group under molten condition equably, produces quality discrepancy at the ectonexine of filament group.And, if the generation of filament group is rocked in refrigerating work procedure, can produce strand irregular.The irregular Quality Down that the uniformity of silk thread is declined, make silk thread of poor quality XOR strand of such filament group ectonexine.
In the past, as the cooling device of melt spinning device, we knew there is CIQ(Circular Inflow Quench, the outer ring-like type of cooling) (reference example is as patent documentation 1,2).CIQ by cooling cylinder be configured in the spinning head of filament spinning component below, from the surrounding of the filament group of walking, to inside, blow out cooling air form in cooling cylinder.Below CIQ, in order to prevent from the way of cooling curing producing in filament group, rock etc., sometimes configure extending.Due to CIQ cooling curing spun filament group under molten condition equably, be therefore widely used in melt spinning device.CIQ is to manufacturing also effective cooling device of high-quality silk thread.
But CIQ is in the past manufacturing on the silk thread that total fiber number and filament number are large and high-quality, there is restriction in the total fiber number of the silk thread that can manufacture and filament number.This is due to the wind speed that blows out length and cooling air of cooling air, to have the cause of restriction.
That is,, if the total fiber number of silk thread and filament number are large, the requirement of cooling air increases.CIQ blows out cooling air from the surrounding of filament group to inside and forms.If increase the length of cooling cylinder make cooling air to blow out length elongated, can increase the air quantity of cooling air.But the cooling air that enters into filament group inside is because the heat exchange with filament group becomes the air of high temperature.If increase the length that blows out of cooling air, the air of filament group inside is sealed in long way from cooling air around, enters into inner high temperature air and is not easy to be discharged to outside.Therefore, even the silk thread that wish and total fiber number and filament number are large increase accordingly the length of cooling cylinder make cooling air to blow out length elongated, filament group inside can not be sufficiently cooled, exists the quality that produces quality discrepancy, silk thread inside and outside filament group to reduce such problem.
And, if increase the speed that blows out of cooling air, can not change the air quantity that blows out length and increase cooling air of cooling air.But, if the speed that blows out of cooling air increases, filament group rock become large, to produce strand irregular.Even if the silk thread that therefore wish and total fiber number and filament number are large increases the speed that blows out of cooling air accordingly, also there is the such problem of strand Quality Down irregular, silk thread that produces.
There is problem as described above in CIQ in the past, the high high-quality silk thread of the uniformity that can manufacture is limited in the not enough about 75de(DENIER of total fiber number) or the not enough about 2dpf(filament number of filament number) silk thread.
Wherein, in patent documentation 3, the technology that opening portion is set between CIQ and extending is disclosed.This opening portion is by attract air to make up the not enough unit of cooling air from outside.But disclosed technology is manufactured high-quality silk even if hypothesis is used patent documentation 3, also exist the cooling air blowing out from CIQ to be arranged on the problem that impact is disorderly, generation filament rocks of the opening portion under CIQ.And, due to disorderly at opening portion cooling air, therefore exist and can not attract fully from opening portion the problem of air.Therefore, rely in patent documentation 3 disclosed technology to manufacture total fiber number and filament number is large and high-quality silk thread is difficult.
In addition, the quantity that spins hole that in patent documentation 3, disclosed melt spinning device is spinning head is 300～2000, mainly manufacture the melt spinning device of staple fibre.Mostly the quantity that spins hole of spinning head be because manufacture the not restriction of quantity that spins hole in the situation of silk, makes to manufacture efficiency comes first and the cause that increases spun filamentary radical.The size of spinning head is also compared and is also become large-scale especially with the spinning head of the silk thread of using for the manufacture of dress material.Like this, manufacture high-quality long stapled melt spinning device and to manufacture the preconditions such as the air quantity from the spun filamentary radical of spinning head, the needed cooling air of CIQ of melt spinning device of staple fibre or desired quality different.Therefore can not will for example be applied to the disclosed technology former state of patent documentation 3 total fiber number and filament number greatly and high-quality long stapled manufacture.
