Embodiment 1

[0009] Embodiment 1, a kind of preparation method of droplet resistant polyester, polypropylene fiber, the compound that contains carboxyl group is grafted on fiber surface, reacts with irradiation grafting method, with acrylic acid as monomer, high-energy electron beam, or (γ ) rays or ultraviolet radiation, and then soaked with magnesium hydroxide or aluminum hydroxide solution. After irradiation grafting acrylic acid, on the one hand, it can cross-link the fiber and change the surface structure of the fiber.

Embodiment 2

[0010] Embodiment 2, the preparation method of droplet-resistant polyester, polypropylene fiber, on the basis of embodiment 1, the acrylic acid solution that concentration is 10~80% is dipped on the surface of polyester fiber or polypropylene fiber fabric, and is irradiated under the electron beam of energy 0.35~5Mev , the radiation dose is 2-30 Mrad, and the anti-dripping fiber is obtained after cleaning and finishing.

Embodiment 3

[0011] Embodiment 3, the preparation method of droplet-resistant polyester and polypropylene fiber, on the basis of embodiment 1, carboxyl group compounds: include some carboxyl compounds containing unsaturated bonds such as acrylic acid, methacrylic acid, and vinyl acetate.

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 [0001] The invention relates to a method for preparing anti-dripping fibers by grafting compounds containing carboxyl groups with polypropylene and polyester as substrates. Background technique [0002] Polyester fiber is currently the most produced synthetic fiber in the world and has excellent comprehensive properties, but its application is limited in some aspects due to the droplet generated after burning. Finding an efficient and non-polluting method to improve fiber flame retardancy and anti-droplet is an urgent concern of people. The fiber can better solve the flame retardant problem after adding appropriate flame retardants. But there is no good solution to the droplet problem. People improve the hydrophilicity of polyester and polypropylene by grafting acrylic acid. Generally, the grafting rate is relatively low. Only when the grafting rate reaches a certain height, can it have the function of preventing dripping. Contents of the invention [00...
