Description
Technical field
The present invention relates to a kind of high-tenacity polyester yarn fiber and preparation method thereof.
Background technology
Polyethylene terephthalate (PET) fiber since the advent of the world, has been obtained rapidly because of its excellent performance
Development, its yield has become the hat of world's synthetic fibers.Polyester fiber has fracture strength and modulus of elasticity height, and resilience is fitted
In, thermal finalization is excellent, and heat-resisting light resistance is good and a series of premium properties such as acid-fast alkali-proof corrosion resistance, and fabric have it is anti-
Wrinkle, the advantages of stiffness is good, so, polyester fiber is widely used in the fields such as clothes, home textile.
Recently as the development of high speed sewing, to ensure the requirement not broken in high speed is sewed, to sewing line strength
Requirement also improve therewith, traditional cotton thread, silk thread are increasingly difficult to meet the requirement of Modern High-Speed sewing, thus intensity it is high,
The good various synthetic fibers especially polyster fibre sewing thread of seamability is because having the advantages that it is protruded：Intensity of sewing is high, wear resistance
Good, heat resistance is high, antistatic property is good, and the dry uniform, moment of torsion of bar is small, tieing is few, with good seamability, is able to rapidly send out
Exhibition.The premium properties of high-tenacity polyester yarn fiber meets the technical requirements of polyster fibre sewing thread.
High-tenacity polyester yarn fiber due to the characteristics of draft temperature in process is high, stretching digit is high, to oil product and
The condition that oils requires high, and the uniformity that oils directly influences the bar dry values and dyeing uniformity of fiber.Selected area update strategy diffusivity
The good oil product of good, wetability, it is overall to improve the uniformity that oils, to improving follow-up Drawdown stability, reduce lousiness and product dye
Color uniformity is particularly important.
The content of the invention
It is an object of the invention to provide a kind of high-tenacity polyester yarn fiber and preparation method thereof, the present invention is by using polyester
Melt, the use of fluorine-containing finish, drawing process and prepare a kind of high-tenacity polyester yarn fiber with high speed spinning.The oil of the present invention
Agent is made up of mineral oil, fluorochemical polyether, phosphate kalium salt and sodium alkyl sulfonate, the concentration of the finish for 10~
20wt%.The composition of the fluorochemical polyether ethylene oxide base monomer used in the present invention is moderate, while introducing [(1,1,2,2-
Tetrafluoro ethyoxyl) methyl] oxirane, the hydrogen bond in system is added, the increase of hydrogen bond is conducive to the raising of cloud point, because existing a bit
Remain to keep the quality of finish while the concentration of finish is increased.The increase of finish concentration can greatly reduce oil
The consumption of energy in agent drying process, saves energy.
A kind of high-tenacity polyester yarn fiber, mainly polyester are by special-shaped spinneret orifice melt spinning, oil agent and roll up at a high speed
Around being prepared；The finish of the oil agent at least includes fluorochemical polyether, the quality of quality >=finish of fluorochemical polyether
45%；The fluorochemical polyether is the nothing of oxirane, [(1,1,2,2- tetrafluoros ethyoxyl) methyl] oxirane and expoxy propane
Copolymer is advised, its structural formula is：
Wherein, m=10~20, n=20~30, k=1~3；
Fracture strength >=4.6cN/dtex of the high-tenacity polyester yarn fiber, elongation at break is 27.0 ± 3.0%.
The characteristics of technique of high-strength polyester fiber has into " two is high " compared with routinely spinning, i.e. draft temperature are high, stretching times
Rate is high.Spinning oil is except the performance should with general polyester filament oil agent, the uniform and stable property of such as convergence, flatness and finish
Outside performance, it is necessary to special performances such as the tensilities and lubricity under film strength and high temperature.Fluorine-containing finish is
The oil product that permeability and diffusivity is good, wetability is good, to improving follow-up Drawdown stability, reduces lousiness and product dyeing uniformity pole
To be important.

For substantial amounts of hydrogen bond, cloud point is improved, is conducive to finish to use the raising of high concentration, energy is saved.Oxirane (EO)/epoxy third
Alkane (PO) ratio is one of most important index of polyethers, and the influence to polyethers performance is also very big.Pfpe molecule chain by multiple EO and
The arrangement of PO chain links is formed, and compared with EO, there is a side base on PO chain links, steric hindrance is larger.EO/PO is than increase, i.e. PO chain links
Reduce, pending methyl group quantity declines, intermolecular space steric hindrance is reduced, the hydrogen chain number formed between hydrone is more, so cloud point
Also raise.The presence of branched structure can reduce surface tension in pfpe molecule chain simultaneously, improve wetting speed, increase with EO/PO,
PO chain links containing branched chain methyl are reduced, thus surface tension rise, and wetting speed slows down, therefore must contain in polyethers macromolecular chain
There is a certain amount of PO.But polyethers relies primarily on the oxygen atom in ether with the hydrogen bond that hydrone is formed, so cloud point rise is limited,
The introducing of [(1,1,2,2- tetrafluoro ethyoxyl) methyl] oxirane, due to the presence of fluorine element, is formed between hydrone
It will increase more than hydrogen bond number, and can further improve the cloud point of polyether aqueous solution；Fluorine element will enter one all in branched positional simultaneously
