Description
Technical field
The present invention relates to a kind of textile processing technology with terylene as stock, particularly one had both improved dacron hydrophilic
Property, also can retain the method for sorting of the excellent ultimate strength of dacron.
Background technology
Polyster fibre in synthetic fibers has excellent combination property, such as: fracture strength and elastic modelling quantity are high, Heat stability is good,
Heat-resisting and light resistance is good etc., owing to plurality of advantages makes polyster fibre be widely used in textile industry, quickly grows, becomes mesh
The chemical fibre that on former world, yield is most, but, terylene is hydrophobic fibre, and the hygroscopicity of its fabric, hydrophilic are poor, it
Regain be only 0.4%, hygroscopicity difference becomes the principal element affecting terylene wearability.Along with carrying of people's living standard
Height, dress ornament has been not only the change of style, color, and quality and function to fabric it is also proposed new requirement, so to carry
The hydrophilicity of high dacron, in order to the wearability improving dacron meets people's demand day by day, but also to guarantee
Original advantage of dacron, saves the energy simultaneously, reduces environmental pollution, is also necessary problem deeply concerned in textile process technology.
The modified method of dacron hydrophilic has a lot, such as Cement Composite Treated by Plasma is modified, ultraviolet irradiation modification, Alkali reduction,
The method etc. that ferment treatment is modified.Electron beam irradiation belongs to the one in high-energy irradiation method, and the response time is short, little to fibre damage,
Percent grafting is high, good endurance, and less demanding to equipment and operation, it is possible to achieve industrialized production, and has efficient energy-saving,
The plurality of advantages such as environmentally friendly.Radiotechnology ionizes mainly by radiation-initiated polymerization thing and excites, thus produces some certainly
By base, further initiating chamical reaction.Containing hydrophilic radical in hydrophilic monomer, on irradiation grafting to dacron, add
Its hydrophilic group, improves the hydrophilic of dacron, if containing phenyl ring in function monomer, phenyl ring can be resisted to a great extent
Radiation, then terylene molecular backbone will be hindered in irradiation process to degrade, reduces radiolysis degree.
Summary of the invention
In order to solve dacron strength loss during electron beam irradiation grafting hydrophilic monomer, the invention provides a kind of warp
Ji environmental protection, and the processing method easily implemented, both improve the hydrophilicity of dacron, and the fracture also remaining dacron is strong
Power.
In order to solve above-mentioned technical problem, the present invention comprises the following steps: first dacron is through low dose irradiation, by irradiation
The dacron crossed pads in the mixed solution containing hydrophilic monomer, function monomer and polymerization inhibitor, the fabric that then will pad
Carrying out secondary high dosage irradiation and make mix monomer and fabric generation graft reaction, the modified dacron fabric ethanol, the acetone that obtain enter
Row cleans, and then washes, dries, finally obtains ultimate strength not by the Hydrophilic Polyester Fiber fabric of irradiation damage.
The present invention is a kind of preferred embodiment: 1. dacron carries out under low dosage is 33-99kGy electron beam irradiation；2.
Irradiated dacron is padded in the monomer solution that mass fraction is 50%, wherein hydrophilic monomer: function monomer is
98:2-90:10, ethanol in mixed solvent: water is 20:80-80:20, polymerization inhibitor is 0.5-2% to the mass fraction of monomer；3.
Then the dacron containing monomer solution is carried out under 110-215kGy irradiation grafting 2 (fabric positive and negatives each of reaction
Secondary), obtain modified dacron；4. modified dacron fabric acetone, ethanol are carried out 2 times and cleans；The most finally carry out
Washing, drying, obtain ultimate strength not by the Hydrophilic Polyester Fiber fabric of irradiation damage.
In the present invention, electron beam irradiation is to carry out in atmosphere, the accelerating potential 130kV of electron beam irradiation, line 1-5mA.
Heretofore described hydrophilic monomer is acrylic acid or acrylamide.
Heretofore described function monomer is styrene or 1-methyl styrene.
Comprising polymerization inhibitor in heretofore described monomer solution, its polymerization inhibitor is green vitriol, and addition is monomer matter
The 0.5-2% of amount.
In the present invention, dacron percent grafting after electron beam irradiation is grafted is 10-25%.
Through the ordering plan of the present invention, making the hydrophilic of dacron be obviously improved, regain is up to more than 3%, same
Time also assures that the ultimate strength of dacron is injury-free after irradiation grafting arranges, and i.e. remains the original advantage of dacron.
Due to the fact that the function monomer incorporated in hydrophilic monomer containing phenyl ring, improve the anti-radiolysis of dacron so that
Dacron hydrophilic remains original fracture strength advantage improving simultaneously, solves the technical bottleneck of chemical graft, and
Method is simple, easily realizes industrialization large-scale production.Present invention can apply to the surface grafting of all kinds of chemical fibre.
Modified dacron fabric after method for sorting of the present invention is processed, can be applicable to the aspect such as clothing, household textiles.
