Description
Technical field
The present invention relates to a kind of copolyesters, the manufacturing method of profiled filament and its devices, more specifically say, are related to one kind
Doping vario-property copolyesters, the manufacturing method of profiled filament and its device.
Background technology
Polyester be using PTA or dimethyl terephthalate (DMT) DMT and ethylene glycol EG as raw material through esterification or transesterification again through contracting
Poly- prepared by reacting polyethylene terephtalate, through polyester fiber made of spinning, trade name terylene is
First big kind of current synthetic fibers, because fiber macromolecular chain rigidity is larger, elasticity modulus is high, fiber is unlikely to deform, therefore
Its fabric intensity is good, does not wrinkle after washing, can not press, it is strong very scrape, be washable easily dry, therefore be a kind of more satisfactory to take spinning
Knit raw material.
Terylene can be used for making special material such as flak jackets, safety belt, tire cord, fishing net, rope, filter cloth and insulation
Material etc., but it is mainly used for one kind as textile raw material, and the official regain of polyester is 0.4%, is hair, flaxen fiber
1/30, the hygroscopicity of polyester fiber is very poor, and fabric resistor rate is up to 1015 Ω cm or more, is typically considered insulator, inhales
The performance of wet antistatic fibre is primarily referred to as antistatic property, i.e., it quickly eliminates ability of electrostatic charge, in standard state RH65%,
At 20 DEG C, if the Ω cm of resistivity≤109, belong to extraordinary antistatic fibre, if resistivity in 1010-1012 Ω cm,
The antistatic fibre belonged to has a meaning of crucial importance in industry, the field of taking, and good hygroscopicity be more conducive to improve it is anti-quiet
The wearing comfort of electricity and fabric.
PTA Chinese names are p-phthalic acid, full name in English Pureterephthalicacid, abbreviation PTA.PTA
It is important one of large Organic Ingredients, 90% or more PTA is for producing polyethylene terephthalate (referred to as in the world
Polyester, PET), 1 ton of PET of production needs 0.85-0.86 tons of PTA and 0.33-0.34 tons of MEG ethylene glycol, at home market
In have 75% polyester for producing polyester fiber, here it is the origin of " chemical fibre raw material PTA " saying, modified poly ester or modified poly-
Ester fiber actually core is exactly modified PTA, general mainly from improving to diformazan for the production technology aspect of modified PTA
The activity and conversion ratio of benzene oxidatoin reaction, reduce the generation of the impurity such as intermediate product, such as p -carboxybenzaldehyde, due to carboxyl
Benzoic acid is mono-functional compounds, and not soluble in water, the acetic acid equal solvent as PTA, therefore is difficult to be detached with PTA, at present
Mainly be separated off with PTA by being dissolved in after hydrogenating reduction after water, generally require p -carboxybenzaldehyde content 25ppm with
Under.
At present for the research of functional polyester, sight is only focused on the conjunction in polyester synthesis monomer PTA, ethylene glycol by people
At the additive with certain function is added in the process, assign polyester certain function with this, therefore the above method is with following
Disadvantage：1) interaction time of direct synthesizing polyester after being polymerize due to PTA and ethylene glycol, additive and polyester is shorter, mutually
Merge poor, synergistic effect is not enough, therefore the effect of cannot give full play to additive；2) many side reactions, shadow are also easy to produce
Ring allomeric functions and the quality effects such as the mechanics of polyester.
The preparation of existing PTA is mainly accounted for from purifying process, that is, reduces the content of the impurity such as p -carboxybenzaldehyde, drop
The low PTA influences of this impurity to reaction in subsequent polycondensation reaction, almost without considering by developing some new PTA product
Kind or modified PTA are applied to some special materials, such as prepare the modification polyester materials with specific function, therefore in the market
PTA products are single, have a single function.
Invention content
Inorganic material has fire-retardant, barrier, anti-aging, antibacterial, antistatic, moisture absorption, health care, the functions such as enhancing, existing skill
Use familiar already in art, such as brick and tile, ceramics, stone, jade, glass, cement, mud.The solarization at one's discretion of brick and tile, mud wall
Drench with rain wind illumination, can centuries it is immortal, ceramic barrier property, which is modern barrier material, to be compared, and the canned yellow rice wine of ceramics can be tens of
Year still mellowness is strong, jade can antibiotic health care have long enjoyed a good reputation, long with not waning, but how people apply inorganic material, have been modified
Machine material, especially high molecular material, assigning high molecular material, there are certain functions, typically inorganic functional material simply to add
Add blending and modifying, single application of function, functional effect is insufficient, and especially organic matrix functional effect is insufficient, matrix
Quality it is difficult to ensure that.For overcome the deficiencies in the prior art, the present invention is through analysis comprehensively, complex optimum prescription, using modern skill
Art means depth physics and chemistry pre-treatment, then inorganic material is evenly dispersed is fused to organic material, the inorganic material in subsequent product
Original function depth integration into high-molecular organic material, over time, inorganic body and organic matrix two-phase interface by
Interface phase is gradually formed, over time interface mutually constantly sprawling extension, the function of inorganic body is extended in company with sprawling into having
Body, assigns the functional effect of its 1+1 ＞ 2, and promotes the comprehensive physical performance of high-molecular organic material.
The present invention by modified PTA to provide have endogenous moisture absorption antistatic polyester and hollow profiled fibre etc. skills

Sprawling extends, and the function of inorganic body is extended in company with sprawling, and in the process, interface is met gradually thicker (like reinforcing bar long-time
In concrete, since the gradual infiltration reinforcing bar of concrete also can be thicker, i.e., reinforcing bar periphery generates interface phase), this interface phase
It is fully merged with organic matrix due to inorganic material-modified dose, thus compared to functions such as common age resister, fire retardants
Additive few then several months, the at most Effective Duration of 1-2, there is more lasting functional period, functional effect also can be more preferable, but
Be above-mentioned interface is formed mutually to need the regular hour, if only after polyester is made addition inorganic material by melt blending,
Interface phase can not be formed in a short time after product is so made, and the present invention just adds inorganic material in early period, obtains enough
Timeliness, can comparatively fast form function modified interface phase after obtained polyester and polyester fiber, persistently play effect；Aoxidize silicon wafer
Palpus, white carbon, conductive mica powder and magnalium hydrotalcite and PTA are combined, the meeting when subsequently preparing polyester and polyester fiber
New synergy is generated, this synergy is presented as the water that can be absorbed in air in synthesizing polyester and polyester fiber
Part, while the charge for being conducive to accumulation shifts in time, improves the antistatic property of polyester and polyester fiber, while at high temperature certainly
The moisture content and the crystallization water that dynamic release absorbs, to have flame retarding function, used whisker modified dose has higher draw ratio, has
The mechanical properties such as intensity, toughening conducive to reinforced resin；The comprehensive performance of fiber prepared by modified PTA is greatly improved, from
And widen it and use field, improve use value；The high molecular synthetic material of the doping vario-property agent of whisker containing nanoscale, collaboration effect
Fruit can also be embodied as under the guide functions of whisker, synthesizing polyester material thermorheologic property improve, be conducive to melt spinning molding and
Drawing-off, surface smoothness can all be greatly improved；Apparatus of the present invention are simple, prepare that convenient, resource utilization is high, green no dirt
Dye.
