Abstract
The invention discloses a fire-resisting polyester fiber and a method for preparing fire-resisting fibers by using the polyester fiber as a substrate and grafting compounds containing carboxy groups. The method comprises the following steps: grafting compounds containing carboxy groups and phosphorous monomers on the fiber surface of the fire-resisting polyester fiber, carrying out reaction by an irradiation grafting method, carrying out high energy electron beam or gamma ray or ultraviolet irradiation by using acrylic acid as a monomer, and then carrying out soaking treatment by using magnesium hydroxide or aluminium hydroxide solution. The invention has the advantages that the method has durable performance of molten drop resistance, non-toxicity and no pollution; the molten drop resisting fiber prepared from polyester fiber and polypropylene fiber having the function of molten drop resistance by the irradiation grafting technique can not generate molten drops during combustion, thus a second fire caused by molten drops during combustion is avoided; and the harm to the skin from the molten drops is avoided when the molten drop resisting fiber is used as clothing fabric.
Description
Technical field
The present invention relates to be a kind of be base material with the terylene, contain the method that carboxylic group compound and phosphorous-containing monomers prepare the fire resistant terylene fiber with grafting.
Background technology
Polyster fibre is the present synthetic fiber of output maximum in the world, has excellent comprehensive performances, but owing to be subjected to thermal contraction, burning back to produce molten drop, application in some respects is subjected to certain limitation.Seeking a kind of efficient, nonpolluting method, to improve fire-retardant, the anti-drippage of fiber be the urgent problems of being concerned about of people.Fiber can solve fire-retardant problem preferably after adding suitable fire retardant.But the good solution of drippage problem neither one.People improve its hydrophily to the terylene graft acrylic acid, and general percent grafting is lower, has only when percent grafting reach a certain height, and could solve the problem of drippage.
Summary of the invention
Technical problem to be solved by this invention is, overcomes weak point of the prior art, provide a kind of efficient, nonpolluting method improves the fiber burning, prevent the preparation method of the fire resistant terylene that drips.
The technical solution adopted in the present invention is: the preparation method of fire resistant terylene contains the compound of carboxylic group in the fiber surface grafting, react with the irradiation grafting method, with acrylic acid is monomer, high-power electron beam or gamma-rays or ultraviolet irradiation carry out immersion treatment with magnesium hydroxide or aluminium hydroxide solution again.
The invention has the beneficial effects as follows: the anti-melt-dropping property of the method is lasting, nontoxic pollution-free; Adopt the irradiation grafting technology to realize that the prepared anti-molten droplet fiber of terylene, polypropylene fibre of anti-molten drop function does not produce molten drop when burning, avoided the spot fire that is caused by the drippage that burns; Avoided molten drop to be bonded at the injury that causes on the skin as garment material.
The specific embodiment
The preparation method of embodiment 1, a kind of fire resistant terylene, the compound and the phosphorous-containing monomers that contain carboxylic group in the fiber surface grafting, react with the irradiation grafting method, with acrylic acid and phosphorous-containing monomers, high-power electron beam or gamma-rays or ultraviolet irradiation carry out immersion treatment with magnesium hydroxide or aluminium hydroxide solution again.Behind the irradiation grafting acrylic acid, on the one hand fiber is played crosslinked action, and the fiber surface structure is changed.The phosphorous-containing monomers buyable.
The preparation method of embodiment 2, fire resistant terylene, on embodiment 1 basis, soak concentration on the dacron surface and be 10-80% acrylic acid solution, under energy 0.35-5Mev electron beam, carry out irradiation, dosage of radiation 1-30Mrad cleans arrangement and promptly makes anti-molten droplet fiber.
The preparation method of embodiment 3, fire resistant terylene, on embodiment 1 basis, the compound of carboxylic group: some contain unsaturated strong carboxyl compound to comprise acrylic acid, methacrylic acid, vinyl acetate etc.
Claims (3)
1. the preparation method of a fire resistant terylene, it is characterized in that: the compound that contains carboxylic group in the fiber surface grafting, and phosphorous-containing monomers, react with the irradiation grafting method, with acrylic acid is monomer, high-power electron beam or gamma-rays or ultraviolet irradiation carry out immersion treatment with magnesium hydroxide or aluminium hydroxide solution again.
2. the preparation method of fire resistant terylene according to claim 1, it is characterized in that: soak concentration on the dacron surface and be 10 one 80% acrylic acid solution, carry out irradiation in energy 0.35-5Mev electron beam, cobalt source or ultraviolet ray, dosage of radiation 1-30Mrad cleans arrangement and promptly makes the fire resistant terylene fiber.
3. the preparation method of fire resistant terylene according to claim 1 is characterized in that: the compound of carboxylic group: some contain unsaturated strong carboxyl compound to comprise acrylic acid, methacrylic acid, vinyl acetate.
