Description
[technical field]
The present invention relates to the fibre technology field, specifically, is a kind of colored profiled polyester multifilament fiber with stable dimension that is applied to textiles for general use and preparation method thereof.
[background technology]
Terylene is since coming out the fifties in last century, and the exploitation on industrial use has obtained very big progress.Polyester industrial yarn has the low characteristics of percent thermal shrinkage because of it, be widely used in industrial cloth such as filter cloth, puggaree, smallware fields such as shelter cloth, traditional low shrinkage type polyester industrial yarn dry-hot shrinkage is greatly about about 2%, the polyester industrial yarn of this xeothermic contraction level is being made into cloth, after coating heat treatment, the cloth cover shrinkage factor is big, shrinks inhomogeneous, easily cause the cloth cover out-of-flatness, therefore can only be used for weaving of smallware.In recent years, because membrane structure material is in architectural developing rapidly, fabric width for fabric is had higher requirement, common low contraction terylene industry silk can't satisfy the requirement of fabric width broad fabrics more than 5 meters, therefore develop the lower polyester industrial yarn of a kind of shrinkage factor, can be used for producing broad fabrics,, seem very urgent to satisfy the demand of membrane structure material.In addition at present, the polyester that domestic manufacturer produces is to adopt high speed method spinning technique, produce, and ABRASION RESISTANCE, fatigue durability is relatively poor, therefore the product weak point in service life that comes out with this fiber weaving.Adopt full-bodied polyester slice to spin polyester fiber; then because the polyester slice with high viscosity molecular weight is big; the melt viscosity height; spinning pressure is higher in the spinning process, and melt post extrusion swelling effect is obvious, and regular meeting the melt deformity takes place or breaks; cause the strand irregularity; have a strong impact on quality of fiber, even can not ordinary production, thereby and add Masterbatch in the common process and also can influence fibrous mechanical property and influence the final products performance.Chinese patent CN1904153A discloses a kind of low contraction terylene fiber preparation method, and it adopts spinning and stretching one-step method technology, comprising: solid-phase tack producing, melt spinning, drawing by high temperature, HEAT SETTING, coiling and molding.Adopt 5 pairs of hot-rolling stretching heat setting process and 4 non-traditional roller technologies.The ultralow contraction terylene industry long filament of preparation has the intensity height, modulus is big, extends for a short time, and heat resistance is good, the advantage that shock-resistant fatigue performance is good needs certain input and the roll banding phenomenon can occur when heat setting temperature surpasses 245 ℃ but section needs solid-phase tack producing to improve equipment simultaneously.A kind of single filament of terylene printing silk screen that Chinese patent CN1654718A and Chinese patent CN1220801C relate to and preparation method thereof has used high-viscosity polyester need carry out solid phase polycondensation equally.And Chinese patent CN100368470C continuous high-strength polyester fiber strengthens the thermoplas tic resin composite, but does not relate to fiber production method and shrinkage factor.
Gather 2,6-naphthalenedicarboxylic acid second two (alcohol) ester, English name: PolyethyleneNaphthalate or polyethylene～2,6-naphthalenedicarboxylate is abbreviated as PEN.It is by 2,6-naphthalenedicarboxylic acid (NDA) or 2, and 6-naphthalene diformic acid dimethyl ester (NDC) reacts a kind of high-performance that forms with ethylene glycol (EG), is similar to the novel homopolymerization polyester of ethylene glycol terephthalate (PET).It has good barrier properties for gases, water proofing property, uvioresistant, heat resistance, chemical proofing and radiation resistance.PEN compares with PET commonly used, and nearly all performance is all more excellent, be over nearly 10 years Application and Development the fastest contain the naphthalene high polymer, can homopolymers or the copolymer form use separately, also can with PET, PC etc. are as high polymer enhancing flexibilizer, purposes is very extensive.Chinese patent CN1273658C and Chinese patent CN1302163C all announced this material in fiber application but do not relate to it and PET blend weaving colored non-conventional fiber.But Chinese patent CN1211204C discloses the production method of a kind of PET/PEN blend or copolymerization film has not related to the preparation of fiber.
Barium sulfate is sneaked into and can be made matrix have better ply adhesion and intensity in the high polymer.Because particle diameter is all less than 0.1mm, its refraction index is very low in addition, has only 1.64, the almost diffusing look ability of barium sulfate.Therefore, they can not influence the transparency of coating and the toning problem of set colored paint.Barium sulfate can reduce colour-difference.Barium sulfate all has stabilization to inorganic and organic pigment, prevents flocculation or loose colour.The barium sulfate particle can be adsorbed on around the pigment particles, increases sterically hindered or charge repulsion stable pigments.Even in flocculation system, add barium sulfate and can both play the effect of repairing or rescuing.Barium sulfate can improve coating gloss and reduce the mist shadow in most of resin systems.As everyone knows, regular meeting causes coating gloss to descend and the mist shadow raises, and also might cause coating variable color or adhesive force decline (thermal capacitance difference) simultaneously after the overbaking phenomenon that causes for a long time too high or time of Yin Wendu in coatings industry.Barium sulfate can effectively address this problem.
Chinese patent CN101177801A discloses a kind of lustrous polyester fiber and preparation method thereof, and this fiber is by barium sulfate, dispersant, and the polyester PET section is formed; Preparation process comprises: surface-treated barium sulfate in advance, and dispersant and PET section blend make the PET section masterbatch that contains barium sulfate; And then with light PET section is arranged by screw extruder melt blending, spinning finished product greatly.This method technology is simpler, and the fiber good luster that makes is better than traditional terylene bright yarn.Chinese patent CN1164679C discloses by nano zine oxide, and the complex polyester that nano barium sulfate and terephthaldehyde's acid polyethylene glycol are formed is used to prepare the radioresistance antiultraviolet fiber.Chinese patent CN1137924C discloses a kind of barium sulfate sol that is used for polyester modification, be a kind of can with water miscible but with water not in the organic solvent of azeotropic, directly carry out the barium sulfate sol that neutralization reaction is produced by barium hydroxide and dilute sulfuric acid.It is produced collosol concentration and reaches as high as 30%, and colloidal particle size is between 10～100nm.Distribution of particles is even, and good stability is difficult for reuniting, and places 3 months its change of size less than 15nm.During use, can arbitrarily dilute, adjust its concentration, directly add in the pet reaction thing as modifier, be a kind of nano material easy to use.The tenacity of fibre of making is good, and can dye by normal temperature and pressure, and fabric can prevent that x and alpha ray penetrate.The Chinese patent CN100355831C disclosure a kind of phosphor-containing flame-retardant copolyester/barium sulphate nano-composite material, contain phosphor-containing flame-retardant copolyester in this material, the content that it is characterized in that phosphor-containing flame-retardant copolyester is 90～99.5% by weight percentage, and the barium sulfate that contains in this composite is 0.5～10% by weight percentage, its particle diameter≤100nm.It is with starting monomer that this invention relates to the method for preparing aforementioned nano composite material, catalyst and phosphorus containing fire retardant copolyester monomer are together, adopt direct esterification method or esterification process preparation indirectly, it is characterized in that before esterification or the esterification aftercondensated before, adding is 0.5～10% nano barium sulfate suspension by weight percentage.Because the nano barium sulfate in this material adds with form of suspension, and adopted the technology of in-situ polymerization, thereby make the composite that obtains to overcome hot property and shortcomings such as mechanical property reduction and fusion drippage that common flame retardant polyester exists, and this material good spinnability, be suitable for high speed spinning, the gained fiber can reach the requirement of civilian fiber.
But it does not all relate to the effect of barium sulfate for the PET/PEN fibre property.
The present invention uses the technology of secondary drawing to make molecular chain orientation degree increase in the fiber by multistage stretching, and the molecule internal stress is reduced, and prevents that fracture of wire and lousiness phenomenon from appearring in fiber thereby reduce tension force.Add barium sulfate and can play intermolecular shuffle effect equally, thereby further improve extensibility.
In closing fine imitated natural fabric process, the profile that initial people imitate natural fabric.From three big kinds of natural fabric, cotton, silk, the fibre morphology of hair sees it is not simple circular cross-section.Cotton fiber is made up of cellulose macromolecule, and its fibre section is near kidney shape, and there is flat cavity inside.Silk and wool all are natural protein fibres.The cross sectional shape of silk is two leg-of-mutton fibroins, is surrounded by one deck silk gum.Wool fibre is cylindrical, and inside is cortex cell, and the surface is a cuticula, is called scale.The cortical layer of wool is a sided configuration, therefore produces spirality crimping.From the structure of above cotton fiber and silk as can be known the both be profiled filament, close fine emulation also from imitated profiled filament starting.
The preparation emphasis of profiled filament is the design of spinnerets hole shape and regulates odd-shaped cross section cooling forming process.The schematic diagram of spinneret orifice shape and gained fibre section shape is referring to accompanying drawing 1.
The degree of profile of profiled fibre cross-section is meant the yardstick that noncircular sectional shape is concavo-convex, also is the degree that circular cross-section is departed from.The big more shape that shows of degree of profile is tortuous more; Degree of profile is more little, approaching more circle.The characterizing method of degree of profile is as follows: the ratio of the circumscribed circle of available profiled filament and the radius of inscribed circle is represented.
Bd＝R/γ
In the formula: Bd is a degree of deformation; R is fiber circumradius (cm); γ is fiber inradius (cm).When the fibre section was circular, degree of deformation reached minimum of a value, and numerical value is 1.Degree of deformation is big more, and degree of profile is big more.
Profiled filament and circular fiber mutually this, in style characteristics, gloss, dyeability, anti-pilling and soil resistance aspect all improve significantly.Characteristics such as natural real silk has soft smooth hand feeling, and fine and smooth and plentiful outward appearance and drapability are good, this soft feel is different from the weakness that does not have the body bone, and this smooth being different from again closed the such smooth sense of fine fabric.These performances are given a kind of fine sense organ of people in a word, but this comprehensive characteristic still lacks a kind of method of evaluation, is called style characteristics here for the time being.
Circular close the soft sense of cunning that fine made fabric has a kind of wax shape, appearance of fabrics is given the old-fashioned and inflexible sensation in a kind of plane of people, and this disadvantage can overcome by cross section special-shapedization.The sense of touch of fabric is relevant with coefficient of friction, increases coefficient of friction, and the sympathetic disappearance of this wax shape makes feel approach real silk.Referring to patent CN2736376Y.
Industry is known together at present, thereby heterotypic fibre can be given the variation of fabric sheen degree and the variation of feel produces the special requirement that different styles satisfies fiber.More common in the market fiber, its shape of cross section generally all are circular, and surface gloss is relatively poor, and the wax sense is arranged, and exist easily dirty, shortcoming such as easily balling-up does not absorb water, and spreadability is little.And use the colouring of Masterbatch method, and dye same degree of depth color chemical fiber, the circular cross-section fiber generally all will use the more pigment of multimass ratio.Compare with monofilament in addition, the uniformity of control multifilament is the key of preparation multifilament fiber.Because multifilament fiber is compared with monofilament, sectional area is little a lot, so spinning temperature control, all differences to some extent of stretch ratio and final color control.
