Abstract
The utility model designs a spinning plate for spinning profiled hollow fiber which comprises a spinning plate main body and spinning holes arranged on the spinning plate. The cross section of the spinning hole is formed by two sections of left and right ladder shapes. The utility model can be made into cross hollow profiled fibre. The cross hollow fiber section provides the fiber with higher water retention, well wet-conductive and ventilation functions. The textile manufactured can absorb sweat of human body and discharge the moisture absorbed by the face fabric with short period of time. The utility model is provided with wicking effect and suitable for sports attire, uniform, etc. The utility model is also suitable for manufacture of geotextile, etc. The Spinning plate for spinning profiled hollow fiber of the utility model can spin hollow fiber which maximizes the ventilation effect of the fiber. The spinning plate is easy in processing, low in cost and long in service life.
Description
Technical field
The utility model relates to a kind of spinnerets that spins special-shaped doughnut.
Background technology
In the prior art, Patent Office of the People's Republic of China announced the utility model patent that name is called " spinning moistured and ventilated filament fiber spinnerets " (Granted publication CN2511691Y) on September 18th, 2002, its spinneret orifice cross sectional shape is cross shape, two ends, the cross shape left and right sides are trapezoidal, two ends are the micropore of two large semicircle shapes up and down, the trapezoidal upper base level in two ends, the left and right sides is bonded as one, is bonded as one with the micropore of a large semicircle shape respectively up and down two sections horizontal bonding places of trapezoidal upper base.Made fiber is cross shape, but is not hollow, and then the moisture transported permeable of gained fiber may not reach optimum efficiency, and the difficulty of processing of spinnerets is higher in addition, makes that the cost of spinnerets is very high, and service life is not long yet.
Summary of the invention
The utility model technical issues that need to address are to disclose a kind of special-shaped doughnut spinnerets of the good moisture transported permeable with high water retention rate of making, to overcome the above-mentioned defective that prior art exists.
The technical solution of the utility model:
The high water retention rate fiber hollow spray filament plate of a kind of spinning, comprise spinnerets main body and the spinneret orifice that is arranged on the spinnerets main body, spinneret orifice on spinnerets in the form of a ring, distribution of shapes such as crosswise, water chestnut shape, fan-shaped or other shapes, said spinneret orifice is made up of a guide hole and a spray silk pore.The cross section of spinneret orifice by about two sections trapezoidal institutes constitute.
The utility model compared with prior art has following advantage:
Use the technical program, can be made into special-shaped doughnut, when from spinneret orifice, spraying as fine high polymer, because the tension force effect of Polymer Surface, the slit of the chemical fibre that two trapezoidal holes come out can closedly form blind bore, because two trapezoidal spacing width length A, B are bigger, the gained fiber has just formed cross hollow, can obtain the doughnut of different cross shapes by the different size of adjusting trapezoidal hole.Because the fibre section of cross hollow makes fiber have high water retention rate, good moisture transported permeable function.Made fabric can be drawn the sweat of human body, and the adsorbed moisture of lining can be discharged in the short period, has wicking.Be suitable for sportswear, military uniform etc., also be fit to make geotextiles etc.
This shows that the spinnerets that is used to spin special-shaped doughnut of the present utility model can spin doughnut, then the moisture transported permeable of gained fiber can reach optimum efficiency, the handling ease of spinnerets in addition, and cost of manufacture is low, long service life.

The specific embodiment
As Fig. 1, shown in 2 and 3, the high water retention rate fiber hollow spray filament plate of a kind of spinning comprises spinnerets main body 1 and the spinneret orifice 2 that is arranged on the spinnerets main body 1, and spinneret orifice 2 distributes on spinnerets in the form of a ring;
The spinneret orifice 2 arrangement number of turns are decided according to spinneret orifice quantity and product requirement, and spinneret orifice 2 is made up of a guide hole 3 and a spray silk pore 4.
The cross section of spinneret orifice 2 by about two sections trapezoidal institutes constitute.Wherein trapezoidal length L is 0.50-0.65mm, two trapezoidal spacing width A are 0.35-0.50mm, and two trapezoidal gap length B are 0.25-0.40mm, and trapezoidal wall thickness S is 0.08-0.12mm, two trapezoidal slit width δ are 0.08-0.12mm, and a trapezoidal side width C is 0.04-0.08mm.The diameter D of guide hole 3 is 0.28-0.40mm, and the height h of spray silk pore 4 is 0.5-0.8mm.

9Metal materials such as Ti are made, and its manufacturing procedure is followed successively by:
1 forges: press spinnerets appearance and size, reserve allowance
2 heat treatments: remove material stress, hardness reaches specification requirement
3 lathes: to requirement, thickness stays 0.5mm by figure paper size car
4 plain grindings: the mill both ends of the surface are to dimensional requirement
5 location: by drawing hole count and arrangement requirement numerical control location
6 borings: slightly bore guide hole, stay the 0.05mm surplus
7 chamferings: 0.5 * 45 ° of aperture chamfering
8 fraisings: the hinge guide hole is to dimensional requirement
9 is flat: flat to special-shaped micropore thickness requirement
10 grind: grind the wire vent facial plane, roughness 0.4
11 clean: with ultrasonic wave workpiece outer surface and guide hole are cleaned up
12 electric pulses: working special-shaped hole
13 clean: utilize ultrasonic wave that the duct is cleaned up
14 checks: press the pass dimension control.
