Description
Technical field
The utility model is related to a kind of chemical fiber production equipments, more particularly, to a kind of hollow colouring polypropylene fiber blank variable yarn
Spinneret in fore-spinning.
Background technology
Air-texturing is also known as air jet texturing, refers to handling long filament using blast injection, to obtain bulkiness and make
It has the processing method of the certain characteristics of similar spun yarn.Its product is air deformation yarn（ATY）, abbreviation blank variable yarn.
Air-texturing technology is that early 1950s DuPont Corporation is studied successfully first, and innovation product is
" Taslan ", therefore also known as " Taslan " technology, European and American countries still continue to use this name so far.But the technology does not have in 25 years after invention
There are much progress, main reason is that thick spy's silk in can only making at that time, is unsuitable for clothing and uses, and nozzle arrangements are undesirable, product
The uniformity is poor, and compressed air consumption is too big, of high cost.Several years up to date, due to being continuously improved to nozzle arrangements, make change
Shape speed is continuously improved, and cost increasingly reduces.Since air-texturing technology has processing precursor wide in variety, Denier range is big, draws
Stretch, deform, mixed fibre can be carried out at the same time, and save twisting process, easy to operate, and product has outside the natural fiber of class spun yarn
It sees, can be flexible and changeable, therefore the attention of fiber producers all over the world is obtained, it has a great development.
Our company once applied for that a kind of nozzle becoming yarn for manufacturing hole, Authorization Notice No. were 2853827 Y of CN,
But using solid space-variant precursor in the preparation process of the blank variable yarn, although the blank variable yarn property prepared by solid precursor
It also can greatly have been promoted, but still cannot meet increasingly harsh use condition.
Our company once applied for a patent a kind of colouring polypropylene fiber its, Authorization Notice No. is CN 201241222Y, this has poly-
It is set in the cross section of tacryl there are one cavity, is hollow colouring polypropylene fiber, therefore its density is significantly smaller than commonly
Polypropylene fibre, simultaneously because possessing hole inside it, therefore its heat-insulating property and water absorbing properties can greatly promote.Cause
If if the precursor that this this polypropylene fibre can be used for blank variable yarn can greatly promote the performance of existing blank variable yarn, but this polypropylene is fine
Used spinneret but can not still prepare the higher hollow colouring polypropylene fiber of qualification rate well when dimension production.
Spinneret is also known as spinning cap.The effect of spinneret is to turn the high polymer molten or solution of viscous state by micropore
Become the thread for having particular cross section shape, strand is solidified to form by setting medium such as air or coagulating bath.By the classification of fiber
It is different with specification, there are different specifications, shape, pass, material etc..Spinneret works under higher temperature and pressure.It is required that
Pressure-resistant, corrosion-resistant and enough mechanical strength.
Such as a kind of a kind of spinneret reported in Chinese patent literature, Authorization Notice No. are CN 204959108
U, the utility model are related to a kind of accessory of the production equipment of textile chemical fiber more particularly to a kind of spinneret.The spinneret is fed
Mouth and discharge port are rectangular, connect the spinneret channel of inlet port and outlet port from top to bottom successively by primary stepped hole, secondary
Stepped hole, three-level stepped hole and go out wire hole and communicate composition, primary stepped hole, secondary stepped hole, three-level stepped hole and goes out wire hole
Section is in the square that the length of side reduces step by step；I.e. spinneret channel is using multistage rectangular hierarchic structure.Spinneret is in use, pass through spray
The rectangular hierarchic structure of multistage in silk channel can carry out high polymer colloid raw material repeatedly moulding, forming degree height, spun filament
It is good with pliability, fluffy degree is high, speciality easy to dye.But there is also its shortcomings for the utility model, such as its
Not in time, formed fiber is solid fibre, the smaller heat insulating ability of surface area to the intensive staple in bulk heat cure of spinneret orifice on spinneret
Can be poor, it cannot be satisfied certain specific harsh use conditions.
Utility model content
To achieve the goals above, the utility model uses following technical scheme：
A kind of spinneret in hollow colouring polypropylene fiber blank variable yarn fore-spinning, including circular spinnerette body,
Perforation is equipped with several special-shaped spinneret orifices on the spinnerette body.
Preferably, the special-shaped spinneret orifice is formed by two arc-shaped spinneret rooms are overlapping so that special-shaped spinneret orifice
In 8-shaped.Spinneret orifice in the spinneret used in the utility model is 8-shaped so that the shape of the fiber of production can be with
The shape of spinneret orifice is consistent.
It is set preferably, each spinneret room circle centre position in the special-shaped spinneret orifice is designed with there are one going out wire hole.
Each spinneret room circle centre position be designed with set there are one go out wire hole enable to melting polyester can be filled up completely 8-shaped
Among spinneret orifice, the made fiber for being is uniform and stable.
Preferably, described, to go out wire hole rounded.
Preferably, the resin straight slot for going out wire hole lower end and being additionally provided with truncated cone-shaped, the resin straight slot upper surface
Identical as wire hole size is gone out, lower face area is more than upper surface area.The resin straight slot that truncated cone-shaped is arranged enables to resin to exist
By when resin straight slot since the diameter in channel becomes smaller, to resin after by resin straight slot enter spinneret orifice when pressure energy
It is enough to be promoted.
Preferably, described go out between wire hole to be additionally provided with baffle.
Preferably, two spinneret rooms intersection in the special-shaped spinneret orifice is also located to be equipped with through-hole needle.Through-hole is set
Needle enables to the inside of formed fiber, and there are holes, to increase its with respect to specific surface area so that its heat-insulating property
It is improved simultaneously.
Preferably, the through-hole needle includes syringe needle and needle body, the needle surface is shiny surface, the needle body
Circumferentially face is uniformly distributed that there are five semicircle diversion columns.
Therefore, the utility model has the advantages that：（1）Profiled filament can be produced；（2）The profiled filament of production
For hollow fibre；（3）Fiber surface area is big.
