Description
Technical field
The invention belongs to fiber preparation field, is related to a kind of preparation method of Polyester Porous silk.
Background technology
Polyethylene terephthalate (PET) fiber since the advent of the world, obtains fast because of the excellent performance that it has
Suddenly develop, its yield has become the hat of world's synthetic fibers.Polyester fiber has high fracture strength, elasticity modulus height, returns
Moderate, the thermal finalization excellent performance of elasticity, 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, so, polyester fiber is standby to be widely used in clothes and family
The fields such as spinning.
, must in spinning process since the dielectric constant of most of PET fiber is smaller, regain is relatively low and friction coefficient is higher
Spinning oil must be used.The main component of finish is surfactant, can form oriented attachment layer on chemical fibre surface, i.e., oily
Film, on the one hand, the hydrophilic radical of oil film can adsorb the moisture in air, form continuous water on the fiber surface towards space
Film, makes charged ion that migration occur on it, reduces between fiber because of the accumulation of electrostatic charge caused by friction, so as to reduce
The sheet resistance of fiber, adds the electric conductivity of fiber, and on the other hand, oil film isolation fiber again can produce fiber certain
Affinity, makes it be not at random there are certain convergence, and in addition, oil film also imparts certain smooth of fiber
Property, makes fiber not be damaged in friction process, and has good feel, can be passed through in spinning winding, stretching,
The operational sequence such as dry, eliminates the electrostatic interaction during textile process, will not occur bad around apron, roller, cylinder etc.
Phenomenon, reduces the generation of lousiness and broken end, ensures 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 behavior of fiber can be changed,
Cause frictional force to increase, cause fiber the other problems such as lousiness, broken end occur, film strength is higher, is more not easily broken, more favourable
In the spinnability of fiber, when finish equably adsorbs on the fiber surface, surface forms the oil film of distribution uniform, and oil film exists
Fiber is rapid after being stretched and uniformly extends, if the viscosity of finish is excessive, is unfavorable for the scattered of finish, forms uniform oil
Film.And with the development of the high speed of polyester filament, ultrahigh speed and Mobyneb fiber, develop that a kind of heat resistance is good, viscosity
The great realistic meaning of finish low, that film strength is high, Lubricity is good and antistatic property is strong.
In the prior art due to spinneret hole count increase make it is obtained pulp freeness is small subtracts, under the permeability of finish
Drop, so as to influence the quality of fiber.
Therefore, a kind of preparation method of soft fine and smooth and good appearance tactile impression Polyester Porous silk is studied as currently urgently solving
Certainly the problem of.
The content of the invention
The purpose of the invention is to overcome to cause the permeability of finish since pulp freeness is small in the prior art
It is deteriorated, the problem of the friction coefficient increase between silk, the quality decline of silk, there is provided one kind has the soft fine and smooth and appearance tactile impression good
Polyester Porous silk preparation method.The use of the finish of the invention containing crown ether, improves the heat resistance and lubricity of finish, lifting
The quality of fiber.
In order to achieve the above object, the technical solution adopted by the present invention is：
The preparation method of Polyester Porous silk, polyester fondant is extruded through metering, porous spinneret, cools down, oil, stretching,
Polyester Porous silk is made in thermal finalization and winding；
The hole count of the porous spinneret is 144~288；
Contain crown ether in the finish to oil, and the content of crown ether is 67.30~85.58wt%, finish of the present invention
The content of middle crown ether need to be kept within the specific limits, and the addition of crown ether is too low, can not be made that viscosity is low, heat resistance is good and
The higher finish of film strength, the addition of crown ether is excessive, other performance indicators of finish can be affected.
Crown ether is a kind of heterocyclic organic compounds, includes multiple ether groups.The wettability of crown ether-like surfactant
Bigger than corresponding open chain compound, crown ether has preferable solubilising, and salt compounds are relatively low in the solubility of organic compound, but with
The solubility for the organic matter of the addition salt compounds of crown ether is improved.Conventional polyester class compound or polyethers in finish
Class, since molecular weight is larger and the effect of hydrogen bond, intermolecular effect is larger, and it is larger to show as kinematic viscosity, after adding crown ether,
Crown ether can be preferably compatible in polyesters compound or polyethers finish system, into polyesters compound or polyethers quasi-molecule
Between chain, the active force between strand is shielded, so as to cause the viscosity of finish system to reduce.Preparation medium is antistatic at the same time
Agent is broadly divided into anionic, cationic and amphoteric surfactant, is mostly deposited containing metal ion or in a salt form
This all makes antistatic additive and polyesters compound in finish or the phase tolerance of polyethers, the addition of crown ether, due to the molten effect of salt
Should, antistatic additive and polyesters compound or the compatibility of polyethers are improved, and then finish oil film strength is improved, this is right
The stability and the product amount of holding of spinning have larger meaning.The index of finish is the embodiment of a composite factor, thus to crown ether
Addition propose certain restriction, too low heat resistance, the advantage of film strength to finish embodies inadequate, and excessive other refer to
Rotating savings is restricted.

Kinematic viscosity after the lotion that concentration is 10wt% is 0.93~0.95mm2/ s, the viscosity that crown ether can reduce finish are mainly
Since crown ether oneself viscosity is relatively low and is pearl small molecule, after introducing crown ether in finish system, crown ether can be preferably compatible to
In polyesters compound or polyether compound finish system, while enter polyesters compound or polyether compound strand
Between, the active force between strand is shielded, so as to reduce the viscosity of finish system；
The film strength of the finish is 121~127N, and the film strength of finish is relatively low in the prior art, generally in 110N
Left and right, this mostly exists containing metal ion or in a salt form mainly due to the antistatic additive of preparation medium, causes to resist
Electrostatic agent can improve film strength and be mainly with polyesters compound or the poor compatibility of polyether compound in finish, crown ether
Salting in effect can be produced after being added due to crown ether, improves antistatic additive and polyesters compound or the compatibility of polyethers,
And then improve finish oil film strength；
