Abstract
The utility model discloses a spinneret plate for generating hollow polyphenylene sulfide short fibers, comprising a spinneret plate body, the spinneret plate body is uniformly provided with spinneret holes, the cross section of each spinneret hole is in the structure of two symmetrical semi-frames in an opposite arrangement and with a certain distance. The spinneret plate is advantageous in that, the internal of the fibers is provided with an air layer, effectively improving heat conduction rate, and improving thermal insulation and heat insulation effects of fiber-made fabrics or heat insulation materials, and due to core absorption effect of the hollow part, the fabrics are provided with better moisture conductivity and permeability.
Description
Technical field
The utility model relates to a kind of spinnerets of production hollow polyphony thioether short fiber.
Background technology
Polyphenylene sulfide (PPS) resin is the crystalline thermoplastic resin that has thiophenyl in the molecular backbone, and its glass transition temperature is 88 ℃, and fusing point is 285 ℃.The PPS fiber of being processed by the PPS resin is a kind of novel high-performance fiber, has 1. good heat resistance; 2. excellent chemical resistance; 3. excellent flame-retardant; 4. good mechanical performance, DIMENSIONAL STABILITY and textile processibility.
The PPS fiber adopts melt spinning method production; Generally adopt wet method, fiber spinning from crystalline state etc. to compare with other high-performance fiber, technology is fairly simple, but can save operations such as solvent recovery; Therefore more environmental protection of production process, production cost are lower; Compare with Nomex fiber, carbon fiber and the glass fibre etc. of the corrosion-and high-temp-resistant of present use, as the material of high temperature resistant protective clothing, the PPS fiber has the double dominant of performance and price.
The PPS fiber of developing at present; Be main mainly with the typical circular staple fibre; Disclosed like publication number CN1603477 is " a kind of linear high molecular weight polyphenylene sulfide fiber melt spinning, stretching heat setting method "; The circular cross-section staple fibre that this method is produced has the fracture strength height, extension at break is low and characteristics such as heat endurance height.Publication number CN101275309 is disclosed to be a kind of " polyphony thioether short fiber and manufacturing approach thereof ", the polyphony thioether short fiber of this invention, and TENSILE STRENGTH reaches more than the 5.0CN/dtex.The polyphenylene sulfide fibre of conventional circular cross-section is compared with the polyphenylene sulfide fibre of the hollow of same specification, and it is relatively poor that it leads moist, gas permeability, heat insulating ability and effect of heat insulation, and this deficiency is particularly evident when as high temperature resistant protective clothing.
The utility model content
The purpose of the utility model has been to provide a kind of spinnerets of production hollow polyphony thioether short fiber.The fibrous inside of the utility model has the existence of air layer, increases pyroconductivity effectively, improves heat insulating ability and the effect of heat insulation of processing fabric or heat-barrier material with this fiber, and owing to the wicking of hollow space, fabric has leads wet, gas permeability preferably simultaneously.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of spinnerets of production hollow polyphony thioether short fiber comprises the spinnerets body, and evenly distributed on the described spinnerets body have a spinneret orifice, and the cross section of spinneret orifice is half frame of two symmetries and arranges the midfeather certain spacing in opposite directions.
Described this body section of spinnerets is circle or rectangle.
The long limit a of the frame in described spinneret orifice cross section is 0.3～0.6mm, and minor face b is 0.1～0.3mm, and the thick c of frame is 0.05～0.15mm, and frame and frame middle ware are 0.05～0.15mm apart from h.
The beneficial effect of the utility model is: the hollow polyphony thioether short fiber of the utility model; Be to adopt linear polyphenylthioether; Melt index 50～150g/10min (ASTMD1238-00) adopts the spinnerets of the utility model to carry out melt spinning under 320～350 ℃ temperature, and spinning speed is 1000～1200m/min; Through the elevated temperature heat typing of 2～5 times stretchings and 180～220 ℃, curl, cut off and make, the fiber number of said staple fibre is 2.2～3.3dtex.The spinneret orifice processing of the utility model is fairly simple; Fibrous inside has the existence of air layer, and the polyphony thioether short fiber hollow rate of processing is high, increases pyroconductivity effectively; Improve lightweight, heat insulating ability and the effect of heat insulation of processing fabric or heat-barrier material with this fiber; Simultaneously because the wicking of hollow space, fabric has leads wet, gas permeability preferably, thus each item good characteristic of bringing into play polyphenylene sulfide more fully and being had.
