Description

A kind of more hollow profiled fibre spinneret plate for producing and production method
Technical field
The present invention relates to technical field of fibre production, especially a kind of more hollow profiled fibre spinneret plate for producing and production Method.
Background technique
Synthetic fibers are since the forties comes out, with the incomparable superiority of its many natural fiber, such as: elasticity height, It is corrosion-resistant, be not afraid of and damage by worms, get the favour of people and rapidly develop.With increasing and added value for synthetic fibers new function It is continuously improved, textile and industrial goods made of synthetic fibers are increasingly liked by people.But general melting Synthetic fibers made of spinning, since its structural form is relatively simple, compared with natural fiber, no matter from structure or performance On still have quite poor away from.
Currently, its cross sectional shape of the heterotypic fibre produced in the market mainly has triangle, three leaves, pentagon, cross, flat Shape, C-shaped, T shape etc., shape is simpler, fiber surface low in glossiness, and there is easy dirty, easy pilling, water imbibition is poor, bulkiness The disadvantages of difference, feel is poor, and elasticity is small.It is had an optimistic view of by more and more chemical fiber enterprises in the market of doughnut.
Summary of the invention
A kind of the purpose of the present invention is to solve the deficiencies of the above technologies and provide fiber fluffy and warming of capable of being promoted The more hollow profiled fibre spinneret plate for producing and production method of property.
In order to achieve the above object, a kind of more hollow profiled fibre spinneret plate for producing designed by the present invention, including spray Filament plate ontology, is provided with several spinneret orifices on spinnerette body, and the spinneret orifice includes being located at spinnerette body close to former The regular cavernous structure of material input one end and the special-shaped central hole structure for exporting one end close to raw material positioned at spinnerette body, regular hole Shape structure and special-shaped central hole structure are interconnected and penetrate through spinnerette body, wherein the shape of the horizontal cross-section of special-shaped hollow structure It is arranged in a linear and is formed by the double semi arch type holes of multiple groups, every group of double semi arch type holes face setting by two semicircle annular distance intervals It is formed, and there is also gaps between two groups of adjacent double semi arch type holes.
Special-shaped hollow structure in each spinneret orifice is made of four groups of double semi arch type holes.
Regular cavernous structure is hollow cylindrical hole, during the junction between special-shaped hollow structure and regular cavernous structure is Empty circular cone structure transition, and the larger diameter end of hollow cone platform structure is connect with regular cavernous structure, hollow cone platform knot The smaller diameter end of structure is connect with special-shaped hollow structure.
The quantity of spinneret orifice is 30, and the spinneret orifice arranges on spinnerette body in multi-ring annular, and each circle Circle is the axial centre of spinnerette body.
A kind of production method of more hollow profiled fibres using the spinneret, specific production stage are as follows: raw material screening, Raw material drying, high-temperature fusion, spiral squeezing, spinneret spray, and cooling oils, coiling and molding.
Preferably, the melt prepared is delivered to booster pump pressurization, melt cooler cooling through melt conveying pipeline Afterwards, each spinning manifold is diverted to by distributing valve;By measuring pump-metered, squeezed out after melt injection spinning pack filtering, then through ring Quenching is made as-spun fibre, and every 10 beam of as-spun fibre is one, every two merge after by traveller, oiling device, lead Enter up- coiler coiling and molding after silk hook, pre- network, the first hot-rolling, the second hot-rolling;Wherein spin manifold temperature control is 270 when spinning DEG C, filament spinning component pressure is 15MPa, and spinning temperature is 270 DEG C, and ring blowing air pressure is 20Pa, and wind-warm syndrome is 20 DEG C;Spinning speed is 4000m/min, for the control of the first heat roller temperature at 80 DEG C, speed is 1200 m/min, and the second heat roller temperature is controlled at 110 DEG C, speed Degree is 4000 m/min.
It is another preferred, the melt prepared is delivered to booster pump pressurization, melt cooler cooling through melt conveying pipeline Afterwards, each spinning manifold is diverted to by distributing valve;By measuring pump-metered, polyester fondant injection spinning pack squeezes out after filtering, then Be made as-spun fibre through ring wind quenching, every 10 beam of as-spun fibre is one, every two merge after by traveller, oil dress It sets, enter up- coiler coiling and molding after traveller, pre- network, the first hot-rolling, the second hot-rolling;Wherein spin manifold temperature controls when spinning It is 275 DEG C, filament spinning component pressure is 17MPa, and spinning temperature is 265 DEG C, and ring blowing air pressure is 22Pa, and wind-warm syndrome is 21 DEG C, spinning Speed is 4000m/min, and for the control of the first heat roller temperature at 78 DEG C, speed is 1300 m/min, and the control of the second heat roller temperature exists 110 DEG C, speed is 4000 m/min.
A kind of obtained more hollow profiled fibre spinneret plate for producing of the present invention and production method, production it is how hollow Profiled filament have the characteristics that bulkiness is high, elasticity is good, warmth retention property is strong, it is soft it is smooth, resilience is good, spreadability is good, extensively It is general to be applied to gum sprayed cotton, spin the fields such as plumage cotton, bedding, insulated cold wear, toy, bunting.
Production special spinning jet of the present invention due to using aforementioned production method and above-mentioned technical pattern, first will when production The melt prepared after booster pump pressurization, melt cooler are cooling, is further separated by melt conveying pipeline by distributing valve Each spinning manifold, by measuring pump-metered, polyester fondant squeezes out after being sent to spinning pack filtering, by circular blow wind or cross air blasting Cooling and solidifying, drawn form fiber.The melt come out from double semi arch type holes of spinneret, according to extruding principle and melt body stream Principle is learned in change, and being surround among 4 groups of formation after spraying in hole has the how hollow fiber type in gap, and 4 groups of double semi arch type holes The shape of assembled arrangement is exactly the global shape of strand cross section.Since the capillary principle of nature is imported textile by the present invention Exploitation, makes the capillary that 30 channels can be formed in fiber, it is thus possible to quick water suction, water delivery, diffusion and volatilization, to keep Skin it is dry and comfortable.The cross-sectional area coverage rate of the more hollow profiled fibers of the present invention is between 70%-80%, in fiber quality (weight Amount) in identical situation, the common heterotypic fibre of surface area ratio increases 50%-60%, thus substantially improves the bulkiness of fiber, bullet Property, so that fiber is had the feel of natural fabric, capillary effect and gas permeability are very high, and wicking capacity substantially exceeds common heterotypic fibre and spins Fabric is more more than cotton.
The present invention can be produced using existing mature technology process, not need the update of equipment, saving is produced into This.
Added value of product of the invention is relatively high, and better results for generation.
Application field of the invention is extensive, such as production military clothes;Make high-grade suit fabric;Make petrochemical industry row Industry, coal industry, electromechanical industries dustproof and anti-explosion clothes;Make health care and the dustless Anti-bacterial clothing of food service industry;Make electronics industry Garment for clean room;Make industrial production work clothes;Make carpet and family's spun articles;Make static removal hairbrush.
