Description

Terylene heavy caliber conveyer belt and preparation method thereof
Technical field
The invention belongs to fiber preparation field, is related to a kind of terylene heavy caliber conveyer belt and preparation method thereof.
Background technology
Polyethylene terephthalate (PET) fiber since the advent of the world, because it is obtained rapidly with excellent performance Ground develops, its yield has become the hat of world's synthetic fibers.Polyester fiber has high fracture strength, elasticity modulus height, rebound Moderate, the thermal finalization excellent performance of property, heat-resisting light resistance be good and a series of excellent performance such as acid-fast alkali-proof good corrosion resistance, And fabric prepared therefrom has the advantages that crease-resistant and stiffness is good, it is widely used in fiber, bottle packaging, film and sheet material Deng field, yield cumulative year after year, position in industry is obviously improved.
But during the polycondensation reaction of synthesis ethylene terephthalate, particularly when generating linear polymer, Since high-temperature oxydation is degraded, also association is linear and cyclic oligomer, cyclic oligomer are due to macromolecular chain in polycondensation phase Hold back what is stung cyclisation and formed, about 70% above is cyclic trimer in cyclic oligomer, cyclic trimer have easily aggregation, The easily characteristic such as crystallization, chemistry and heat-resistant stability height, generation cyclic trimer can there are following influence on polyester processing：(1) meeting The blocking of filament spinning component is caused, influences the service life of fondant filter and component；(2) can be separated out in fiber heat-setting process, It is deposited on heating roller, causes frictional force to increase and heat irregular；(3) dyeing course can be made centered on cyclic trimer Dye aggregation is simultaneously adhered to fiber surface, and phenomena such as dyestuff color dot, spot and dyeing defect occurs in fiber surface, influences to be weaved by it The feel and coloured light of the fabric formed, the normal flow velocity of melt can be limited by being simultaneously filled with the cyclic oligomer of pipeline and valve Degree, causes stock-dye irregular, poor reproducibility；(4) fiber surface is adhered to, causes, around yarn difficulty, broken yarn and thickness occur Phenomena such as uneven, influence the mechanical properties such as fracture strength and the elongation at break of fiber, seriously affect product quality.
Since the dielectric constant of most of PET fiber is smaller, regain is relatively low and friction coefficient is higher, in spinning process Spinning oil must be used.The main component of finish is surfactant, can form oriented attachment layer on chemical fibre surface, That is oil film, on the one hand, the hydrophilic radical of oil film can adsorb the moisture in air, be formed on the fiber surface continuous towards space Moisture film, make charged ion that migration occur on it, reduce between fiber because of the accumulation of electrostatic charge caused by friction so that The sheet resistance of fiber is reduced, adds the electric conductivity of fiber, on the other hand, oil film isolation fiber again can produce fiber Raw certain affinity, makes it be not at random there are certain convergence, in addition, oil film also imparts fiber one Fixed flatness, makes fiber not be damaged in friction process, and has good feel, can be passed through in spinning The operational sequence such as winding, stretching, dry, eliminates the electrostatic interaction during textile process, will not occur around apron, roller, The bad phenomenons such as cylinder, reduce the generation of lousiness and broken end, ensure the quality of fiber product.
After being ruptured due to the oil film of fiber surface under high temperature, high speed and certain pressure, the friction row of fiber can be changed To cause frictional force to increase, causing fiber the other problems such as lousiness, broken end occur, film strength is higher, is more not easily broken, more Be conducive to the spinnability of fiber, when finish equably adsorbs on the fiber surface, surface forms the oil film of distribution uniform, Oil film is rapid after fiber is stretched and uniformly extends, if the viscosity of finish is excessive, is unfavorable for the scattered of finish, is formed equal Even oil film.And with the development of the high speed of polyester filament, ultrahigh speed and Mobyneb fiber, develop a kind of heat resistance The great realistic meaning of finish good, viscosity is low, film strength is high, Lubricity is good and antistatic property is strong.
High tenacity polyester fiber fiber applications are extensive, available for fields such as car belt, conveyer belts.But height is prepared at this stage The main problem that intensity polyester fiber faces has two, first, finish volatilization is very fast and is easily bonded in fiber surface so that system The fiber inequality rate obtained is higher, poor-performing；Second, the volatilization of oligomer remains in the surface of spinneret in fiber, fibre is caused Lousiness is tieed up, influences the quality of fiber.
