Abstract
The present invention relates to a kind of full-dull network stretch yarn and preparation method thereof, by polyester fondant through metering, extrusion, cooling, oil and wind and be made POY, POY through wire leading pipe, network, heating stretching, false twisting, thermal finalization and coiling and molding are made DTY, that is full-dull network stretch yarn, contain crown ether in the finish to oil, and the content of crown ether is 67.30~85.58wt%, wherein matt agent is dispersed with polyester fondant, matt agent is unformed titanium dioxide and the mixture of unformed silica, or it is calcium carbonate and the mixture of unformed silica.The glossiness of obtained full-dull network stretch yarn<20%, crimp contraction >=35%, curling stability is 75~85%.The method of the present invention advantages of simple, obtained full-dull network stretch yarn have the advantages that full-dull and function admirable, there is fabulous promotional value.
Description
Technical field
The invention belongs to fiber preparation field, is related to a kind of full-dull network stretch yarn and preparation method thereof.
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, oil film can be reduced between fiber because of the accumulation of electrostatic charge caused by friction, so as to reduce the sheet resistance of fiber, increased
The electric conductivity of fiber, on the other hand, oil film isolation fiber again can produce fiber certain affinity, there is it certain
Convergence and be not at random, in addition, oil film also imparts the certain flatness of fiber, makes fiber in friction process
It is not damaged, and there is good feel, the operational sequences such as winding, stretching, drying can be passed through in spinning, are eliminated
Electrostatic interaction during textile process, will not occur, around bad phenomenons such as apron, roller, cylinders, to reduce lousiness and broken end
Generation, 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, meeting
Change the friction behavior of fiber, cause frictional force to increase, cause fiber the other problems such as lousiness, broken end occur, film strength is got over
Height, is more not easily broken, and is more conducive to the spinnability of fiber, and when finish equably adsorbs on the fiber surface, surface, which is formed, to be divided
The more uniform oil film of cloth, oil film is rapid after fiber is stretched and uniformly extends, if the viscosity of finish is excessive, is unfavorable for finish
It is scattered, form uniform oil film.In addition with the development of the high speed of polyester filament, ultrahigh speed and Mobyneb fiber, people
Also have increasingly higher demands, the performance pair of finish for the heat resistance of finish, viscosity, Lubricity and antistatic property
There is highly important influence in the quality of final obtained fiber.
In recent years, the application range of full-dull network stretch yarn gradually increases as made from PET, but prepared by the prior art
Full-dull network stretch yarn glossiness it is still higher, it is difficult to reach daily required extinction effect, and due to preparation process
The middle finish evaporation rate that uses is very fast, is easily bonded in fiber surface, causes the uneven rate of fiber higher, have impact on fibre
The performance of dimension.Thus, study that a kind of glossiness is relatively low and the full-dull network stretch yarn of function admirable becomes current urgently to be resolved hurrily
The problem of.
The content of the invention
The purpose of the invention is to overcome in the prior art full-dull network stretch yarn there are the problem of, there is provided Yi Zhongguang
Damp degree is low and full-dull network stretch yarn of function admirable and preparation method thereof.The present invention uses unformed titanium dioxide and nothing
The mixture or calcium carbonate of the silica of sizing and the mixture of unformed silica are inorganic matt particle, inorganic
Uniform particle is dispersed in PET, destroys crystallization and the orientation of PET, hence in so that fiber surface is in delustring state；The oil to oil
Contain crown ether in agent, since the more conventional smooth agent of crown ether has lower viscosity, the volatilization point of higher so that the finish containing crown ether
Friction coefficient smaller, and there is more excellent heat endurance, so as to improve the processing performance of fiber, reduce lousiness and show
The appearance of elephant, improves the performance of fiber.
In order to achieve the above object, the technical solution adopted by the present invention is as follows：
