Description
Technical field
The utility model belongs to apparatus for melt spinning technical field, and in particular to a kind of cross air blasting of melt-spun PLA silk
Cooling device.
Background technology
Foregoing melt-spun PLA silk is " melt spinning method spinning PLA silk ", and PLA silk is that " PLA is fine
Dimension ".Acid fiber by polylactic is, using the amyloid agricultural product such as corn, wheat, beet as raw material, lactic acid to be generated through glucose fermentation
Afterwards, then through polycondensation and melt spinning it is made.Acid fiber by polylactic is that a kind of raw material can be planted, easily planted and discarded object is in nature
In can natural degradation synthetic fibers.It can be analyzed to carbon dioxide and water in soil or seawater through microbial action, burning
When, poison gas will not be distributed, pollution is not resulted in, be a kind of ecological fiber of sustainable development, its have fabric feel and
The strong points such as drapability is good, uvioresistant and excellent processing characteristics, suitable for various fashionable dresses, easy dress, sports goods and health
Articles for use etc., have broad application prospects.
As is known in the industry, the spinning melt under high temperature is after the spinneret orifice extrusion on spinneret, and strand is by wound draw roller
Drawing, fibre is pulled into by the melt that spinneret orifice is extruded downwards., it is necessary to using air cooling equipment by by spinneret in aforementioned process
The rapid cooled and solidified of flow-like strand extruded in spinneret orifice is into fiber.
And then as is known in the industry, lateral-blowing air cooling device is to the quality of the cooling effect of flow-like strand to fibrous finished product
The Specifications of physical property, the processing characteristics of finished fiber and fiber can have a direct impact.Specifically, such as
Fruit lateral-blowing air cooling device temperature is too low, i.e. the temperature of cross air blasting is too low, fibrous outer quick solidification occurs because fiber is quenched
But fiber inner core is still in the situation of melt state, make fiber formation core-skin fibre, core-skin fibre is because hair is stiff, harden, rear road
Drafting multiple can be significantly reduced and strength declines；, whereas if lateral-blowing air cooling device temperature is too high, because fiber cooling is not thorough
Bottom, lousiness increases in process of production, or even the inter-adhesive phenomenon between easy generation single fiber during spinning winding.
More and as is known in the industry, because the viscosity of acid fiber by polylactic melt is big, thus relative to common chemical fibre
Say that the technological requirement of spinning is more harsh, if foregoing side-blown air cooling is undesirable（Such as cross air blasting is too high or too low for temperature）,
Then to its physical index as strength can produce large effect.
It is no lack of in disclosed Chinese patent literature and believes on implementing the technology of side-blown air cooling to foregoing melt shape strand
Breath, it is typical " to be used for the method for melt-spun and cooling multifilament as what invention patent mandate notification number CN10313090B recommended and set
It is standby ", by the explanation to the 0043rd to 0045 section of the patent specification, by the drum of the structural system of lateral-blowing air cooling device
Blower fan introduces external air into air blowing chamber（Custom claims " air blowing chamber ", as follows）, the air into air blowing intracavitary is through breathable
Air blowing wall laterally blows to the melt shape strand for coming from spinning-nozzle（Patent claims monofilament）, monofilament bar is formed after the cooling of melt shape strand
And exported through filar guide, obtain long filament.Although the technique effect that the patent formula is recorded with specification, being due to can not be real
Existing gradient cooling, that is to say, that because the air themperature of the upper, middle and lower of air blowing chamber is identical, thus can not
Melt shape strand is implemented in the different height direction corresponding to air blowing wall with different temperature to cool down, then when temperature is too high or
When too low, the problem of easily there is the influence fiber quality that applicant is mentioned above, and it is more prominent for acid fiber by polylactic.
Also, " being used for melt-spun and the method and apparatus for cooling down many synthetic threads " that Authorization Notice No. CN102869819B is provided, relatively
In previous patent, the patent employs cooling tube cooling, is specifically：Come from the melt shape strand of spinning manifold successively through pressure
Room, cooling tube formation silk thread, then exported through filar guide.Because the patent is for silk thread, thus it is very thin for preparing
Fiber and without referential meaning.Especially, by the teaching of its specification, the cooling air provided by cooling air source according to
It is secondary by the road（Patent claims " main line "）, supply line be branched pipe, adjusting means（Including choke valve and adjusting handle）Into
Cooling tube is cooled down to the melt shape strand by way of cooling tube, thus because the air themperature for entering all cooling tubes is identical
, even if same cooling tube, the air themperature and indifference of its upper, middle and lower bottom then equally exist the applicant
The influence fiber being mentioned above（Influence silk thread）The problem of quality, and it is more prominent for acid fiber by polylactic.
Quality for above-mentioned prior art and in order to ensure acid fiber by polylactic, it is lasting and beneficial that the applicant has made
Explore, technical scheme described below is produced under this background.
The content of the invention
Task of the present utility model is that the molten shape strand for providing a kind of spinneret orifice contributed to coming from spinneret is implemented
