专利汇可以提供Radiation grafting of poly(ethylene glycol) dimethacrylate and other monomers onto polyester fibers专利检索，专利查询，专利分析的服务。并且A mixture of poly (ethylene glycol) dimethacrylate and an alkali metal salt of an ethylenically unsaturated organic acid is polymerized by means of an ionizing radiation on the surface and inside of a polyester fiber material such as poly (ethylene terephthalate) fiber. The treated polyester fiber material is provided with the antistatic and hygroscopic properties as well as durability by washing.，下面是Radiation grafting of poly(ethylene glycol) dimethacrylate and other monomers onto polyester fibers专利的具体信息内容。

权利要求

2. The method of claim 1, in which is employed poly (ethylene glycol) dimethacrylate in which the molecular weight of its ethylene glycol group is about 300 - 800.

3. The method of claim 1, in which polymerization is carried out so that percent of weight increase is about 0.2 - 10 percent by weight of the polyester fiber material to be treated.

4. A durable antistatic and hygroscopic polyester fiber material having an ethylene terephthalate component, said polyester fiber material being selected from the group consisting of i a poly(ethylene terephthalate)fiber, ii a copolymeric polyester fiber of ethylene terephthalate and ethylenediisophthalate, characterized in that an aqueous mixture of poly(ethylene glycol) dimethacrylate with a molecular weight of 300 - 800 for the poly(ethylene glycol) group and an alkali metal salt of an ethylenically unsaturated organic acid selected from the group consisting of styrene-sulfonic acid, methacrylic acid and acrylic acid wherein said salt is present in an amount of about 1-50 parts by weight per 100 parts of poly(ethylene glycol) dimethacrylate is polymerized to form a water-insoluble polymer on the surface and inside of said fiber material by means of an ionizing radiation selected from the group consisting of gamma rays, beta rays, X-rays, electron beam in a dosage of about 102 - 108 rad. at a dose rate of 102 - 109 rad./hr. and ultraviolet light.

5. The durable antistatic and hygroscopic polyester fiber material of claim 4, in which percent of weight increase after the polymerization is about 0.2 - 10 percent by weight of the polyester fiber material to be treated.
