Abstract
The utility model relates to a spinneret plate for large-capacity spinning for polyphenylene sulfide fibers, which comprises a spinneret plate body, wherein spinneret orifices are formed on the spinneret plate body, at least one air duct leading to the middle of the spinneret plate from the periphery of the spinneret plate is arranged on the spinneret plate, and a spinneret orifice is not formed on the spinneret plate body in the air duct area. The spinneret plate is suitable for large-capacity spinning for polyphenylene sulfide fibers, and enables all the fibers spun out through the spinneret plate to be cooled to meet the process requirements.
Description
Technical field
The utility model relates to special chemical fiber spining technology field, relates in particular to a kind of spinning spinneret that is used for the big capacity spinning of polyphenylene sulfide fibre.
Background technology
Polyphenylene sulfide (being called for short PPS) resin material is a kind of novel macromolecular material, its fusing point is up to 285 ℃, spinning temperature is far above the spinning temperature of traditional synthetic fiber (polyester, polypropylene, polyamide etc.), therefore in polyphenylene sulfide fibre spinning moulding production process, the spinning temperature of polyphenylene sulfide fibre is in 300～340 ℃ of scopes.In order to reduce production costs, effectively improve product competitiveness, increase the product profit space, the general mode that enlarges spinnerets diameter, increase spinnerets hole count that adopts realizes the big capacity spinning production technology of polyphenylene sulfide fibre, improves the production capacity of production line spinning equipment.As shown in Figure 3, its structure of spinning spinneret that is used for the big capacity spinning of polyphenylene sulfide fibre that present stage generally uses comprises: spinnerets body 1 evenly is densely covered with on the body and reaches thousands of spinneret orifice 3.In the spinning production process, the polyphenylene sulfide high-temperature fusant is extruded spinnerets body 1 under certain pressure, form the high-temperature fusant thread that gathers through spinneret orifice 3, these melt thread temperature very high (290～325 ℃), through the ring cold wind blower, need spin in journey and very short time certain, evenly cool off and form stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree; Because the diameter of spinnerets is bigger, tow is many, and cooling air is difficult to pass densely covered layer by layer peripheral tow and arrives the spinnerets middle part, and the tow that is positioned at the spinnerets middle part can not reach technological requirement because of cooling, and causes difficulty in spinning, influences product quality.
The utility model content
Technical problem to be solved in the utility model is: a kind of spinning spinneret that is used for the big capacity spinning of polyphenylene sulfide fibre that whole tow are all cooled off reach technological requirement is provided.
For addressing the above problem, the technical solution adopted in the utility model is: the spinning spinneret that is used for the big capacity spinning of polyphenylene sulfide fibre, comprise: the spinnerets body, the spinnerets body is provided with spinneret orifice, spinnerets is provided with at least one air channel that can be led to spinnerets middle part by the spinnerets periphery, on the spinnerets body in the zone, air channel spinneret orifice is not set.
Spinnerets is provided with two air channels that can be led to the spinnerets middle part by the spinnerets periphery, and the center of body is all passed through in described two air channels, and vertical mutually.
Spinnerets is provided with three air channels that can be led to the spinnerets middle part by the spinnerets periphery, and an end in described three air channels all is connected to the center of body, and the other end in air channel all is connected with body exterior, and three air channels evenly distribute along hoop.
Described spinneret orifice evenly gathers on the body that is positioned at the air channel region exterior.
The beneficial effects of the utility model are: can make high-temperature fusant that spinnerets sprays in official hour and certain spinning on the journey, all cooling reaches technological requirement and forms the stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree uniformly, thereby makes spinning effect better.

The specific embodiment
Below by specific embodiment the spinning spinneret that the utility model is used for the big capacity spinning of polyphenylene sulfide fibre is described in further detail.
Embodiment 1:
As shown in Figure 1, the spinning spinneret that is used for the big capacity spinning of polyphenylene sulfide fibre, comprise: spinnerets body 1, on spinnerets body 1, evenly be provided with spinneret orifice 3, spinnerets is provided with two air channels 2 that can be led to the spinnerets middle part by the spinnerets periphery, the center of body 1 is all passed through in described two air channels 2, and vertical mutually, on the spinnerets body 1 in 2 zones, air channel spinneret orifice 3 is not set.
Embodiment 2:
As shown in Figure 2, the spinning spinneret that is used for the big capacity spinning of polyphenylene sulfide fibre, comprise spinnerets body 1, on spinnerets body 1, evenly be provided with spinneret orifice 3, spinnerets is provided with three air channels 2 that can be led to the spinnerets middle part by the spinnerets periphery, and an end in described three air channels 2 all is connected to the center of body 1, and the other end in air channel 2 all is connected with body 1 outside, three air channels 2 evenly distribute along hoop, on the spinnerets body 1 in 2 zones, air channel spinneret orifice 3 are not set.
Operation principle of the present utility model is: during spinning, the polyphenylene sulfide high-temperature fusant is under high pressure extruded spinnerets body 1, be divided into densely covered high-temperature fusant thread through spinneret orifice 3, these high-temperature fusant threads are through the ring cold wind blower, evenly cool off and form stable preliminary draft silk with certain degree of crystallinity and pre-orientation degree, at this moment, because no spinneret orifice 3 in 2 zones, air channel, just there is not tow to stop the current of cooling air yet, cooling air can enter into the spinnerets middle part by the spinnerets periphery by air channel 2, thereby the tow that is positioned at the spinnerets middle part also can be cooled off reach technological requirement, whole tow that spinnerets is sprayed all cool off and reach requirements, thereby make spinning effect better.
