Abstract
The invention provides a preparation method of a directly-spun low-pilling polyester wool-type long fiber bundle. The preparation method is characterized by comprising the step of injecting and adding TMP and/or a tetrahydrofurfuryl alcohol-based silicide anti-pilling additive on an esterfied oligomer pipeline of a PET polyester production line, wherein the addition amount of TMP accounts for 0.5-1.3wt% of the amount of PET polyester, the addition amount of the tetrahydrofurfuryl alcohol-based silicide anti-pilling additive accounts for 1.1-3.0wt% of the amount of polyester, and the PET polyester production line is a direct-spinning production line. According to the preparation method, the added TMP can branch polyester, the added tetrahydrofurfuryl alcohol-based silicide substance plays a role in branching or crosslinking in the polyester synthesis process, and the aims that the fiber still has favorable spinning performance under the low-viscosity condition and keeps relatively high stability in the spinning processing process are achieved. The structure of TMP is asymmetric, and TMP plays a role in stopping (inhibiting) crystallizing in macromolecules after copolymerization, so that the modulus of PET and the lateral strength of the fiber are greatly reduced. In addition, a direct drawing technology is adopted, so that the anti-pilling physical property of polyester fiber is enhanced.
Description
Technical field
The present invention relates to the manufacture method of a kind of direct fabrics low balling-up polyester wool type fiber endless tow, belong to synthetic fiber and manufacture field.
Background technology
Natural and synthetic fiber were made fabric and can there is pilling effect after longer service times, and pilling effect refers to fiber irregular spherical aggregation on the surface of the fabric, and single fiber stretches out from yarn, is out of shape from the teeth outwards and forms spheroid due to friction.This phenomenon especially easily comes across in synthetic fiber, especially polyethylene terephthalate (PET) fiber, and because polyester fiber intensity is high, these spheroids can not come off, but are deposited on the surface, produce ugly outward appearance.The cross section of fiber is that circle or fiber number are particularly evident more than the pilling effect of 2.77dtex textiles, because compared with natural fabric, polyester fiber has high strength, and particularly cross section is that circle or fiber number are higher more than horizontal (direction, the fibre section) intensity of the fiber of 2.77dtex.
By the method for machinery, spheroid can be removed in principle, such as, be brushed away by the method for textile finishing or scrape off.But this method is required great effort very much and costliness, and can not prevent the formation of new spheroid.
By carrying out to polyester fiber the generation that modification can reduce balling-up.The object of modification prevents the formation of spheroid or promotes fibrous fracture and the spheroid of removing formation.The fiber that have employed this modification is called as low balling-up fiber.Object of the present invention is just to provide a kind of low balling-up fiber like this.
Another kind method is by carrying out modification to polyester fiber, falls low-fiber transverse strength, prevents the generation of spheroid, or fiber easily ruptures to remove spheroid.Usual manner is the molecular weight reducing polymer.In order to make polymer still obtain excellent processability at lower molecular weight, the viscosity of polymer melt should be increased by crosslinking agent.The multifunctional molecule in strand can be engaged in bunching process, be used as crosslinking agent.The example of this crosslinking agent comprises multi-group alcohol's (pentaerythrite), polybasic acids and silicon compound or phosphorus compound.Then make melt spinning again of cutting into slices, the removal moisture step of polymer controls more difficult in the process, very easily causes the instability of spinning, and the uniformity of fiber is unstable.
Other method implemented after making textiles, polyester fiber is degraded, and for this purpose, adds hydrolysing activity compound (acid, alkali and organic derivative) in the polyester.Principle is the key increasing easy pyrolysis or hydrolysis in polymer chain, and when fabric product or pencil thing such as being dyeed after spinning technique, these keys are ruptured by hydrolysis method.But the fibrous fracture percentage elongation of process is too high like this, and the too low machinability causing spinning of fracture strength is poor, thus is not suitable for the demand of clothes textiles.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides the manufacture method of a kind of direct fabrics closer to natural wool performance low balling-up polyester (PET) wool type fiber endless tow.
The technical scheme that the present invention takes is: the manufacture method of the direct fabrics low balling-up polyester wool type fiber endless tow that a kind of anti-pilling property strengthens, the manufacture method of direct fabrics low balling-up polyester wool type fiber endless tow, on Oligomer pipeline after the esterification of PET Pet Production Line, trimethylolpropane (TMP) and/or tetrahydrofurfuryl alcohol base silicide class ANTIPILLING additive are added in injection, TMP addition is 0.5 ~ 1.3%wt of PET polyester, tetrahydrofurfuryl alcohol base silicide class ANTIPILLING additive, addition is 1.1 ~ 3.0%wt of polyester, this PET Pet Production Line is direct spinning line.
Further, tetrahydrofurfuryl alcohol base silicide class ANTIPILLING additive is 3 (4 hydrogen chaff oxygen base) methyl-monosilane and/or 4,4 hydrogen chaff TMOSs.
Further, described TMP or tetrahydrofurfuryl alcohol base silicide class ANTIPILLING additive are allocated after in ethylene glycol (EG) solution and are injected interpolation.EG is the synthon of polyester PET, has good solubility property to TMP and tetrahydrofurfuryl alcohol base silicide, therefore can accurate measurement and product even.If modified PET has other monomer, such as diethylene glycol (DEG) (DEG) also can as solvent.
Further, its step comprises:
A, precondensation and final minification gather: on the Oligomer pipeline after PET esterification, TMP and/or tetrahydrofurfuryl alcohol base silicide class ANTIPILLING additive are added in injection, obtain melt;
B, spinning: melt enters manifold spinning, utilize the heat exchanger on melt Conveying pipeline, temperature before making polyester fondant enter spinning manifold controls at 282 ~ 285 DEG C, spinning body temperature controls at 285 ~ 289 DEG C, the temperature of quenching wind and the difference of melt temperature between 256 ~ 266 DEG C, and adopt quenching mode from inside to outside;
C, sizing: the tow be spun into stretches through a water one vapour two-stage, then after machine crimp, under relaxation condition, adopts hot-air to shape, and temperature controls at 130 ~ 160 DEG C.
The invention provides a kind of polyester fiber of melt modification direct fabrics, add TMP and can make polyester branches, add tetrahydrofurfuryl alcohol base silicide class ANTIPILLING additive and fall low-fiber transverse strength, add tetrahydrofurfuryl alcohol base silicide class material in process of polyester synthesizing play the effect of collateralization or Cross-linked, but it is different from the effect of Pentaerythritols, tetrahydrofurfuryl alcohol base silicide class is also unstable in PET macromolecular structure, especially can decompose under high temperature (being greater than PET crystallization temperature) and weak alkaline aqueous solution condition, make large molecular breakdown, the lateral strength of fiber obviously reduces, therefore there is the effect of ANTIPILLING.The object of collateralization or Cross-linked still has good spinning properties under low-viscosity condition, and fiber also still keeps higher stability in textile process process.Unstable structure makes in textile finishing processes, destroys the microstructure of original polyster fibre, particularly can weaken the lateral strength of fiber, make it more easily to rupture and play reduce balling-up or balling-up after the object easily removed.The structure of TMP is asymmetric, after copolymerization, plays the effect of prevention (obstruction) crystallization in large molecule, greatly reduces modulus and the fiber lateral strength of PET.And adopt direct slivering technology, enhance the ANTIPILLING physical property of polyester fiber, particularly still there is the low pilling property of expectation after stock-dye, and known Weaving device can be utilized in addition to produce and process this fiber.
