Abstract
The present invention provides a method of preparing molten drop preventing fiber with polyester and polypropylene fiber as base material and through grafting carboxyl group compound. The method includes irradiation grafting reaction to graft compound containing carboxyl group onto acrylic acid monomer under the irradiation of high energy electron beam, gamma ray or ultraviolet ray; and the subsequent soaking treatment in magnesium hydroxide or aluminum hydroxide solution. The method results in lasting molten drop preventing performance and has no toxicity and contamination. The polyester and polypropylene fiber through the molten drop preventing treatment produces no molten drop during burning, and can avoid secondary fire and damage to skin caused by molten drop.
Description
Technical field
The present invention relates to be a kind of be base material with polypropylene fibre, terylene, contain the method for carboxylic group compound anti-molten droplet fiber with grafting.
Background technology
Polyster fibre is the present synthetic fiber of output maximum in the world, has excellent comprehensive performances, but because the burning back produces molten drop, application in some respects is subjected to certain limitation.Seeking a kind of efficient, nonpolluting method, to improve fire-retardant, the anti-molten drop 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 molten drop problem neither one.People improve its hydrophily to terylene, polypropylene fibre graft acrylic acid, and general percent grafting is lower, has only when percent grafting reach a certain height, and just has the function of anti-molten drop.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art, and provide a kind of efficient, nonpolluting method to improve the drop resisting polyester of fire-retardant, the anti-molten drop of fiber, the preparation method of polypropylene fibre.
Can take following technical scheme to realize purpose.
The preparation method of a kind of drop resisting polyester, polypropylene fibre: the compound that contains carboxylic group in the fiber surface grafting, react with the irradiation grafting method, with acrylic acid is monomer, and high-power electron beam or gamma-rays or ultraviolet irradiation carry out immersion treatment with magnesium hydroxide or aluminium hydroxide solution again.
The relative prior art of present technique has following advantage and effect
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 molten drop that burns; Avoided molten drop to be bonded at the injury that causes on the skin as garment material.
The specific embodiment
In conjunction with the embodiments technical scheme is described in detail.
The preparation method of embodiment 1, a kind of drop resisting polyester, polypropylene fibre, the compound that contains carboxylic group in the fiber surface grafting, react with the irradiation grafting method, with acrylic acid is monomer, high-power electron beam or (γ) ray 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 preparation method of embodiment 2, drop resisting polyester, polypropylene fibre, on embodiment 1 basis, soak concentration on terylene or polypropylene fabric surface and be 10～80% acrylic acid solution, under energy 0.35～5Mev electron beam, carry out irradiation, dosage of radiation 2～30Mrad cleans arrangement and promptly makes anti-molten droplet fiber.
The preparation method of embodiment 3, drop resisting polyester, polypropylene fibre, on embodiment 1 basis, the compound of carboxylic group: some contain the carboxyl compound of unsaturated bond to comprise acrylic acid, methacrylic acid, vinyl acetate etc.
Claims (3)
1, the preparation method of a kind of drop resisting polyester, polypropylene fibre, it is characterized in that: the compound that contains carboxylic group in the fiber surface grafting, react with the irradiation grafting method, with acrylic acid is monomer, high-power electron beam or (γ) ray or ultraviolet irradiation carry out immersion treatment with magnesium hydroxide or aluminium hydroxide solution again.
2, the preparation method of drop resisting polyester according to claim 1, polypropylene fibre, it is characterized in that: soak concentration on terylene or polypropylene fabric surface and be 10～80% acrylic acid solution, carry out irradiation in energy 0.35～5Mev electron beam, cobalt source or ultraviolet ray, dosage of radiation 2～30Mrad cleans arrangement and promptly makes anti-molten droplet fiber.
3, the preparation method of drop resisting polyester according to claim 1, polypropylene fibre is characterized in that the compound of carboxylic group: some contain the carboxyl compound of unsaturated bond to comprise acrylic acid, methacrylic acid, vinyl acetate.
