Abstract
The invention relates to a method for grafting and modifying the surface of a polyester textile through microwave irradiation. As grafting reaction is carried out by adopting a microwave method, the method has the advantages of short reaction time, uniform reaction and little influence on the property of the textile. Hydroxyethyl methacrylate is taken as a grafting monomer; and the grafted polyester textile has obviously improved moisture absorption property, good molten drop resistance, stable and durable effect and strong water resistance and is bonded through chemical bonds in a reaction process.
Description
Technical field
The present invention relates to a kind of surface graft modification method of polyester textile, namely use microwave method to carry out surface grafting to polyester textile, to improve anti-melt-dropping property and the moisture pick-up properties of polyester textile.
Background technology
Polyester is one of most widely used engineering plastics, and total output has occupy the prostatitis of world's engineering plastics.Polyester textile is widely used in tent, interior trim, air bag and clothes etc. because have the advantages such as powerful high, that ABRASION RESISTANCE is good.Polyester textile itself belongs to inflammable macromolecular material, and when being heated, fiber very easily shrinks, and causes the melting drippage, skin ambustion, cause casualties, molten drop also can cause other flammable body burnings, and the hygroscopicity extreme difference of polyester textile, absorption of perspiration during as clothes etc., gas permeability are bad, this has also limited its application in daily life, and fabric has larger specific area, therefore, it is carried out surface graft modification, improve the focus that its some specific function becomes research.
Microwave is wavelength high-frequency electromagnetic wave in the 1-1000nm scope, has high penetration capacity.During the microwave irradiation polar substances, the polar substances molecular energy absorbs microwave, makes to rotate and the quickening of spin motion speed, the activation energy of polar substances molecule is reduced greatly, so microwave has certain catalytic action.The reaction of carrying out under microwave irradiation, as long as in reactant mixture, reactant can fully contact, ratio is suitable, just have higher reaction efficiency, and reaction is more even, microwave has cleaning, efficient, quick, easy and simple to handle, power consumption is low, pollute the characteristics such as few, obtain developing rapidly application at the field of chemical synthesis in recent years, the scholar that Canadianizes was applied to organic synthesis with microwave technology first in 1986, and Murruy was used for synthetic polymer research first with microwave technology in 1994.Microwave applications is also few in the report of the surface light graft modification of fabric, especially be applied to polyester textile surface unprecedented report especially, this is because compare with natural fabric, there is no active group in the structure of polyester textile, and therefore carrying out graft modification on its surface has certain difficulty.
Bright spot of the present invention is: one, first the microwave grafting technology is applied to the surface graft modification of polyester textile, not yet reports both at home and abroad at present microwave method is applied to the synthetic textiles surface graft modification.It is fast that the microwave grafting modification has reaction speed, grafting is even, need not the advantages such as stirring, and in microwave method graft modification process, monomer and fabric are the reactions of carrying out, and have avoided microwave to contact with the direct of fabric in the aqueous solution, therefore less to the performance impact of fabric itself, reaction condition is gentle, and microwave evenly penetrates, and technique is simple, equipment investment is few, and is pollution-free.Two, the present invention is used for hydroxyethyl methylacrylate anti-molten drop and the hygroscopicity modification of polyester first, the anti-molten drop of polyester textile after modification and hygroscopicity obviously improve, and the surface graft modification monomer is to be connected by covalent bond with fabric, therefore, fabric washability after modification is good, and effect is lasting.
Summary of the invention
The object of the invention is to microwave method is applied to the surface graft modification of polyester textile, by adding initator, that hydroxyethyl methylacrylate is monomer-grafted to the polyester textile surface, to improve its anti-melt-dropping property and moisture pick-up properties.
The present invention is to provide a kind of microwave surface grafting method of polyester textile, concrete experimental procedure is:
Polyester textile is at 0.4% Na

3Poach 30min in solution, then use acetone extracting 12h, again fabric is immersed in initiator solution pre-reaction a period of time under microwave condition, soak two through two and roll (padding machine rotating speed 1m/min, pressure 0.3MPa), fabric is changed in the monomer solution that configures in advance, after reaction a period of time, take out washing under microwave condition, boil again 30min in boiling water, to remove the homopolymers of fabric face.Dry to constant weight in baking oven again.Pre-reaction time is 20min, and initator is selected K
2S
2O
8, concentration is 0.25-2%, monomer is hydroxyethyl methylacrylate, and concentration 2.5-20%, the reaction time is 40-80min in monomer solution.Reaction temperature is that room temperature rises to constant temperature after assigned temperature, and temperature is 70-90 ℃, and microwave power is 300-600W.Keeping bath raio during reaction is 1:40, and for guaranteeing the stability of microwave induced temperature, total solution amount is not less than 300g.
The invention has the advantages that and use microwave method to promote graft reaction, the microwave penetration ability is strong, and graft reaction is evenly occured, and does not need to stir.Be swift in response, efficient is high.And microwave reaction cleaning, pollution-free, equipment operating is simple.Use the fabric after the microwave method grafting, less to the performance impact of itself, and the anti-melt-dropping property of fabric obviously improves, and moisture pick-up properties reaches improvement.
