Abstract
The utility model relates to a spinneret plate of three-blade cross hollow type fiber. The spinneret plate is characterized by being formed by 100-2,000 arranged spinneret holes of the same structure, wherein each spinneret hole consists of three line-styled hole units which are identical in shape and size; two ends of each line-styled hole unit are arc-shaped; three hole units are arranged in a radiation manner in equal distance and equal included angles along one same circle center; a certain interval is formed between adjacent parts of every two hole units so that the hole units are not communicated with each other. The spinneret plate can be used for producing fiber with an irregular structured cross section and high internal hollowness as well as excellent moisture absorption, sweat release and heat preservation functions, a fabric is high in brightness and fluffy and comfort in hand feeling, and the fiber can be widely applied to fabrics of high-class warm-up clothes, underwear and the like.
Description
Technical field
The utility model relates to a kind of spinnerets, especially a kind of spinnerets for the production of three leaf hollow type fibers.
Background technology
The cross sectional shape of fiber and the characteristic of fiber are closely related, by means of the change of fibre section shape, can obtain the needed various characteristics of people.Conventionally, the cross section profile of Profile Polyester Fibre is irregularly shaped, can make fabric have fluffy sense, glossiness and moisture transported permeable; The cavity that hollow polyester fiber is continuous because fibrous inside has, has reduced the quality of fiber, can improve the heat-insulation warm keeping of fabric.And have abnormity, hollow feature concurrently in the polyster fibre of one, and the two advantage of having combined platform, fabric integrates frivolous ventilative and cold-proof comfort, has outstanding superiority, can meet the demand of many high-grade clothings.
At present, baroque multi-functional fiber is still in the research and development stage, and the technology of Profiled hollow fiber is urgently development also.Therefore the precision design of spinnerets and spinning technique control are had higher requirement, design a kind of simple structure, precision is high, and the Profiled hollow fiber spinnerets of good spinnability has great importance.
Summary of the invention
The purpose of this utility model is to provide a kind of spinnerets for the production of three leaf hollow type fibers, coordinate corresponding spinning and aftertreatment technology, can produce cross section is trilobal cross structure, the polyster fibre that inner hollow degree is high, has excellent moisture absorbing and sweat releasing and heat-preserving function concurrently, and fabric glossiness is high, feel is fluffy comfortable, the production that this spinnerets is hollow profiled fibre provides novel device, its precision is high, and spinnability is good, has met the demand of high-grade fabric.
For achieving the above object, the designed spinnerets of the utility model adopts following preferred technical scheme:
Spinnerets is arranged and is formed by 100～2000 identical spinneret orifices of structure, each spinneret orifice is comprised of with the identical unit, yi word pattern hole of size three shapes, two ends, unit, yi word pattern hole are circular shape, unit, three holes is the equidistant emitting shape of angle that waits to be arranged along the same center of circle, and unit, every two holes adjacent part is at regular intervals not to be communicated with mutually.
Above-mentioned yi word pattern hole element length a is 0.15～0.5mm, and width b is 0.05～0.3mm, the circular shape that two ends, unit, yi word pattern hole are cocurrent and parallel, and the central angle of circular arc is 10～180 °.
Above-mentioned unit, yi word pattern hole, the spacing c of adjacent part is 0.04～0.1mm between two.
Above-mentioned 100～2000 spinneret orifices be take spinnerets center as the center of circle, are multilayer concentric round type and evenly arrange.
The beneficial effects of the utility model:
The polyster fibre of this spinnerets spinning, cross section is trilobal cross, there is cavity centre, degree of profile and the degree of hollowness of fiber reach perfect match, and fabric has excellent wetness guiding perspiration discharging and heat-insulation warm keeping function concurrently, and glossiness is high, frivolous comfortable, fluffy and flexible, for the design of high-grade warm-up or underwear, its breathable heat insulating and comfort level are that common thermal fabric is difficult to reach.Each two ends, yi word pattern unit of spinneret orifice of the present utility model are designed to novel arc structure in the same way, than similar right-angle structure or Symmetrical Circular Arc structure, the effective cavity volume in the middle of increased fiber, improve degree of hollowness, under the prerequisite that reaches moisture transported permeable effect, further improve warmth retention property.This spinneret plate structure is simple and easy simultaneously, has fully guaranteed the spinnability of high accuracy and fiber.
Accompanying drawing explanation
The spinneret pore structure schematic diagram of Fig. 1 the utility model spinnerets
The specific embodiment
The utility model is described in further detail by reference to the accompanying drawings.
Embodiment
The spinneret orifice of spinnerets is multilayer concentric round type by 200 identical spinneret orifices of structure and arranges, if Fig. 1 is the structural representation of each three leaf hollow type spinneret orifice, the structure of three yi word pattern spinneret orifice unit is identical with size, the length of unit, yi word pattern hole is 0.4mm, width is 0.2mm, the central angle of two ends circular arc is 90 °, and the spacing of unit, every two holes adjacent part is 0.05mm.
Melt spinning after polyester slice is dry, adopts this spinnerets to extrude, supporting suitable spinning, drawing-off and aftertreatment technology, and its cross section of the polyster fibre obtaining is trilobal cross, there is the cavity running through at center, and maintains the original spinnability of fiber.This fiber surface forms sufficient wicking passage, and there is higher degree of hollowness inside, gives the moisture absorption of fabric excellence and breathes freely and fluffy insulation.
Above are only illustrating of the utility model possible embodiments, not technical scope of the present utility model is imposed any restrictions, allly do not depart from any trickle modification, equivalent variations and the retouching that the utility model is done, still belong in technical scope of the present utility model.
