Abstract
The invention relates to a method for modifying a polyester fiber woven tape and a modified polyester fiber woven tape product prepared by the method, which adopts a method combining solution modification and solid modification and adopts hyperbranched polyester end chain modification technology to introduce fluorine-containing groups into polyester fibers.
Description
Technical Field
The invention relates to the technical field of polyester fiber modification, in particular to a modified polyester fiber woven tape product and a preparation method thereof.
Background
The safety belt is widely applied to various fields of social production at present and is one of the most important guarantees of personnel safety in specific occasions. The most widely used woven belt is a high-altitude anti-falling safety belt which is widely used for high-altitude construction operation. The braid of the current high-altitude operation safety belt is mainly made of polyester fiber and has the characteristics of light weight, high strength and the like.
The application scenes of the high-altitude anti-falling woven safety belt are various, such as disaster relief, electric power and ship fields, and some special requirements are also put forward on the performance of the woven belt, such as insulation, water resistance, fire resistance, corrosion resistance, friction cutting resistance and the like. The existing solution is to adopt special fiber to make the mesh belt separately for the scene with special demand, but the mesh belt is high in cost, single in scene and poor in universality. In addition, the modification of the current special fiber is generally implemented in the fiber manufacturing process, which determines that the existing woven belt cannot be correspondingly modified, thereby causing huge hidden danger.
Therefore, there is an urgent need for a method for modifying the finished product of polyester fiber fabric woven tape, which can improve the main indexes of fire-proof insulation cutting resistance and the like of the existing finished product woven tape (which can be new or used). Making it possible to adapt to the requirements of most extreme scenarios.
Disclosure of Invention
In order to solve the problems, the invention provides a method for modifying a polyester fiber woven tape and a modified woven tape product thereof, and the specific method comprises the following steps:
a liquefaction modification treatment step and a solidification modification treatment step;
the liquefaction modification treatment step comprises the steps of firstly preparing a liquid modifier, and treating the polyester fiber woven belt by adopting the liquid modifier; the solidification step is a step of carrying out solidification treatment on the polyester fiber woven tape after the liquefaction modification treatment, the solid modifier and other solid additives.
Preferably, the liquid modifier is prepared by polymerizing modified hyperbranched polyester and fluorine-substituted aliphatic amide compound; the curing treatment is a method for combining the solid additive and the polyester fiber woven tape by adopting a hot pressing method.
Preferably, the modified hyperbranched polyester is obtained by modifying the terminal group of the hyperbranched polyester by using acrylic acid and glycidol trimethyl ammonium chloride.
Preferably, the hyperbranched polyester is prepared by taking ethoxy pentaerythritol as a core and 2, 2-dimethylolpropionic acid as a branching unit, and tests show that the hyperbranched polyester with too high or too low molecular weight has poor effect, and the preferred molecular weight is between 1500 and 3000; wherein the aliphatic amide compound is 3- (4-fluorophenyl) -2-acrylamide; the solid additive is a mixture of hydroxyapatite and silica.
Preferably, the modified hyperbranched polyester and 3- (4-fluorophenyl) -2-acrylamide are polymerized by adding allyl glycidyl ether and adopting ammonium persulfate as a polymerization initiator.
Compared with the prior polyester fiber fabric treatment method, the method has breakthrough improvement. Firstly, from the basic steps of the method, the method combines the high-temperature curing step after the liquid soaking modification, and through practical tests, the method finds that the mode of firstly liquid modifying and then curing modification not only plays a role in simply combining the liquid modifier and the solid modifier, but also unexpectedly improves the modification effect of the previous liquid soaking modification in the subsequent high-temperature curing process.
Secondly, the invention innovatively provides a fluorine-containing modifier. In recent years, the organic fluorine industry has been rapidly developed, and in the field of general textile finishing, fluorine-containing water repellent has been highly regarded as having excellent water-repellent, oil-repellent, stain-repellent, and antistatic properties. However, the fluorinated finishing agents reported to date are not ideal for modifying polyester fiber tapes. After repeated attempts, the applicant finds that the liquid modifier prepared by introducing the fluorine-containing group in a hyperbranched polymer polyester modification mode and then treating the polyester fiber fabric woven belt can bring particularly excellent effects. The hyperbranched polymer has the characteristics of a large number of terminal groups, high reactivity and the like, and can purposefully realize certain specific effects by chemically modifying the terminal groups. After continuous trial, the hyperbranched polyester is modified, and the modified hyperbranched polyester and the fluorine-containing vinyl monomer are polymerized, so that the hyperbranched polyacrylamide organic fluorine product modifier is prepared.
Tests prove that the polyester fiber woven tape modified by the modifier has good waterproof, oil-proof, antifouling and antistatic properties. The meshbelt after will handling carries out hot pressing solidification with the mixture of hydroxyapatite and silica powder jointly again, and not only the wearability and the high temperature resistance of meshbelt have obtained obvious promotion after the solidification, and it is unexpected that its waterproof, grease-proof, antifouling and antistatic properties have also all obtained the enhancement.
The modification method can greatly improve various indexes of the finished polyester fiber woven belt, can be applied to woven belt production, and can also be applied to the maintenance of the existing woven belt. Has the advantages of excellent effect, low cost, wide application range, high economic value and social value.
The technical contents of the present invention will be described in detail with reference to specific embodiments.

Cooling to about 50 ℃, adding a proper amount of boron trifluoride diethyl etherate as a catalyst, dropwise adding a small amount of glycidol trimethyl ammonium chloride, reacting for 24 hours under the condition of heat preservation, and evaporating to remove the solvent to obtain a light yellow viscous liquid.
(2) Polymerization preparation of fluorine-containing hyperbranched liquid modifier
And (2) sequentially adding the product obtained in the step (1), 3- (4-fluorophenyl) -2-acrylamide, dimethyl diallyl ammonium chloride, allyl glycidyl ether and an ammonium persulfate aqueous solution into a reaction container.

Tests prove that the treated woven belt has better antistatic property and water and oil resistance compared with the untreated woven belt, and after a plurality of washing tests, the attenuation of the antistatic property and the water and oil resistance is very small, so that the liquid modifier also has excellent durability.
Example 3 curing modification step
Adding hydroxyapatite and silicon dioxide powder into a container, adding water at room temperature by using sodium hexametaphosphate as a surfactant, stirring, and dispersing by ultrasonic waves to prepare a dispersion liquid.
And uniformly spraying the prepared dispersion liquid on the surface of the liquid modified terylene woven tape, preheating for 5 minutes at 130 ℃, hot-pressing for 80 seconds at 240 ℃ and 4MPa, washing with water, and drying to obtain a solidified and modified terylene woven tape product.
After testing and curing modification, compared with the non-cured modified woven belt, the cutting resistance of the modified woven belt is doubled, and the dirt resistance of the modified woven belt is also obviously improved.
Surprisingly, after the solidification modification, compared with the simple liquefaction modification, the antistatic property, the water resistance and the oil resistance brought by the liquefaction modification are not reduced, but are improved to a certain extent, particularly the durability, after dozens of times of water washing, various properties are still kept good, and compared with the simple normal modification, the durability improvement is greatly improved.
From the specific embodiments, it can be found that the method of the invention innovatively combines liquid modification and solid modification, the two are mutually promoted, and the hyperbranched polyester end chain fluorine modification is used for carrying out the fluorine modification of the polyester fabric in combination with the original application, so that the electric resistance, the water resistance and the cutting resistance of the woven belt are better improved, and the performance of the existing woven belt is greatly improved.
