Problems solved by technology

However, the polyester fiber prepared by this method usually has low strength, poor wear resistance, and short service life. On the other hand, it is not durable, which is also a waste of resources and is not conducive to environmental protection.

Abstract

The invention discloses a polyester fiber capable of preventing neutron radiation. The polyester fiber comprises the following raw materials by weight: 40-70 parts of polyethylene powder, 10-20 parts of diethyl citrate, 1-5 parts of a brightening agent, 2- 4 parts of ferric oxide, 20-40 parts of a heavy metal compound, 2-6 parts of terephthalic acid, 1-5 parts of phosphorous acid, 1-3 parts of terylene chips, 2-4 parts of ethylene glycol, 1-3 parts of zinc oxide, 4-10 parts of barium titanate powder, 1-3 parts of a coupling agent and 1-3 parts of dicumyl peroxide. According to the invention, terylene is used as a carrier and copolymerized with the heavy metal compound, so the prepared polyester fiber has an anti-radiation function and all the characteristics of terylene; and the prepared polyester fiber is simple to produce, low in cost, good in elasticity and not prone to deformation and is durable, corrosion-resistant, insulating, stiff and smooth, etc.

Description

technical field [0001] The invention belongs to the field of polyester fibers, and in particular relates to a neutron radiation-resistant polyester fiber. Background technique [0002] Polyester fiber is an important variety of synthetic fibers, and it is the trade name of polyester fiber in my country. It is a fiber-forming high polymer prepared from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or transesterification and polycondensation reactions - polyethylene terephthalate Esters, fibers made by spinning and post-processing. Polyester fiber is the simplest one among the three major synthetic fibers, and the price is relatively cheap. In addition, it has the characteristics of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, crispness, easy washing and quick drying, etc., so it is loved by people. There are many types of polyester fiber fabrics. In addition to weaving pure poly...
