Description
Technical field
The present invention relates to a kind of superbright light polyester DTY fiber and preparation method thereof.
Background technology
Polyethylene terephthalate (PET) fiber is since appearance, and obtain because of the performance of its excellence and rapidly develop, its output has become the hat of world's synthetic fiber.Polyester fiber has fracture strength and elastic modelling quantity is high, and resilience is moderate, and HEAT SETTING is excellent, a series of premium properties such as the good and acid-fast alkali-proof corrosion resistance of heat-resisting light resistance, and fabric has the advantages such as crease-resistant, stiffness is good, so, the fields such as polyester fiber is widely used in clothes, family is spun.
Superbright light polyester fiber, mainly by melt spinning, cross section special-shapedization etc., give polyester fiber and there is gloss as real silk and soft, that fabric becomes clear sense and soft elegance silk light sensation, not only have outside excellent optical characteristics, fabric feeling is abundant, bulkiness, good permeability, have superbright flash effect.Its product is mainly used in the pile fabrics such as silk like fabric fabric, wool-like fabric, corduroy, knitting wool, drapery etc.Especially in the large field of clothing, decoration and fabrics for industrial use three, wide market prospects and economic benefit is had.
Superbright light polyester DTY fiber adopts triangle light FDY to be raw material, its residual elongation is little, highly high, fiber rigidity is large, spinning speed is high, frictional force between strand and frictional disk is larger, fibre section type shape easily deforms, and degree of profile reduces, and oil product need have boundling, lubrication, the characteristic such as antistatic, high temperature resistant.To oil product and the conditional request that oils high, the uniformity that oils directly has influence on bar dry values and the dyeing uniformity of fiber.The oil product that selected area update strategy diffusivity is good, wettability is good, the overall superbright light polyester DTY fiber that improves to oil uniformity, to ensureing that the quality of product will play larger effect.
Summary of the invention
The object of this invention is to provide a kind of superbright light polyester DTY fiber and preparation method thereof, the present invention prepares a kind of superbright light polyester DTY fiber by the use and high speed spinning utilizing the polyester fondant of high-quality, special spinneret orifice and fluorine-containing finish.Finish of the present invention is made up of mineral oil, fluorochemical polyether, phosphate kalium salt and sodium alkyl sulfonate, and the working concentration of described finish is 10 ~ 20wt%.The composition of the fluorochemical polyether ethylene oxide base monomer used in the present invention is moderate, introduce [(1 simultaneously, 1,2,2-tetrafluoro ethyoxyl) methyl] oxirane, add the hydrogen bond in system, the increase of hydrogen bond is conducive to the raising of cloud point, because still keeping the quality of finish a bit while the working concentration at increase finish.The increase of finish working concentration can greatly reduce the consumption of energy in finish dry run, conserve energy.
A kind of superbright light polyester DTY fiber, described superbright light polyester DTY fiber mainly polyester is obtained by the preparation of special-shaped spinneret orifice melt spinning, oil agent and high-speed winding; The finish of described oil agent at least comprises fluorochemical polyether, 45% of the quality of the quality >=described finish of fluorochemical polyether; Described fluorochemical polyether is the random copolymer of oxirane, [(1,1,2,2-tetrafluoro ethyoxyl) methyl] oxirane and expoxy propane, and its structural formula is:
Wherein, m=10 ~ 20, n=20 ~ 30, k=1 ~ 3;
The index of described a kind of superbright light polyester DTY fiber: fracture strength (cN/dtex): >=4.0; Fracture is stretched
Long rate (%) 26.0 ± 5.0; DTY end section: equilateral triangle, dyeing M rate (%) >=97.
Superbright light polyester DTY fiber dyeing M rate refers to the DTY silk of dye uniformity >=4.5 grade and the ratio of the DTY silk sum of all dyeing, and its height is the important indicator weighing DTY yarn quality quality.Only has the elastic filament that dyeing M rate is high, the homogeneity of color in dyeing course.
Described fluorochemical polyether can not only provide good level and smooth, emulsification and wetting function, can also provide a large amount of hydrogen bonds, improve cloud point, be conducive to the raising that finish uses high concentration, conserve energy for finish system.Oxirane (EO)/expoxy propane (PO) ratio is one of most important index of polyethers, also very large on the impact of polyethers performance.Pfpe molecule chain is arranged by multiple EO and PO chain link and forms, and compared with EO, PO chain link has a side base, sterically hindered larger.EO/PO is than increasing, and namely PO chain link reduces, and pending methyl group quantity declines, and intermolecular space steric hindrance reduces, and the hydrogen chain number formed between hydrone is many, so cloud point also raises.In pfpe molecule chain, the existence of branched structure can reduce surface tension simultaneously, improves wetting speed, increases with EO/PO, PO chain link containing branched chain methyl reduces, thus surface tension raises, and wetting speed slows down, and therefore must contain a certain amount of PO in polyethers macromolecular chain.But the hydrogen bond that polyethers and hydrone are formed mainly relies on the oxygen atom in ether, so cloud point raises limited, [(1,1,2,2-tetrafluoro ethyoxyl) methyl] introducing of oxirane, due to the existence of fluorine element, and the hydrogen bond number formed between hydrone is many will be increased, the cloud point of polyether aqueous solution can be improved further; Fluorine element is all in branched positional simultaneously, will reduce the surface tension of polyethers further.When finish forms oil film, fluorine element can, at surface enrichment, due to the characteristic of fluorine element, make the flatness of finish be further enhanced.
As preferred technical scheme:
A kind of superbright light polyester DTY fiber as above, the relative molecular weight of described fluorochemical polyether is 1000 ~ 4000; The cloud point of described fluorochemical polyether is 50 ~ 100 DEG C; Surface tension 25 ~ the 40dyn/cm of described fluorochemical polyether.
A kind of superbright light polyester DTY fiber as above, also comprises mineral oil, phosphate kalium salt and sodium alkyl sulfonate in described finish; Mineral oil has good heat resistance, has good compatibility with other component, and it has and oils evenly, and the feature that film strength is high, effectively can also reduce the coefficient of friction of fiber and metal, and the cohesive force of increase fiber, is conducive to boundling.Adopt anionic antistatic agent, can realize surface hydrophilic, the heat resistance of phosphate kalium salt is relatively good, good antistatic behaviour, can the antistatic effect of fortifying fibre, is conducive to the boundling of fiber.Sodium alkyl sulfonate add the penetrating power that can improve finish, make finish to be attached on tow in the short period of time uniformly, effectively can reduce the appearance of lousiness, broken end.
By weight: mineral oil is 25 ~ 35 parts; Fluorochemical polyether is 50 ~ 70 parts; Phosphate kalium salt is 8 ~ 15 parts; Sodium alkyl sulfonate is 2 ~ 7 parts;
