Technical Field
[0001] This invention relates to the field of radiation protection fabric technology, specifically to a high-elasticity radiation protection fabric based on synthetic filaments and its preparation method. Background Technology
[0002] Some radiation-proof fabrics are made of fibers coated with conductive metal. The conductive metal on the surface of the fibers can easily lose some of its metal after repeated washing, resulting in a decrease in the metal content of the radiation-proof fabric and thus reducing its radiation protection ability.
[0003] The shortcomings of existing anti-radiation fabrics are:
[0004] 1. The prior art CN106956476B discloses a radiation protection fabric. The present invention discloses that its shielding effectiveness can reach more than 80dB, while having good adhesion, wearability, softness, abrasion resistance, antibacterial and bacteriostatic properties and elasticity, significantly improving the comfort and practicality of wearing, and has a wide range of applications.
[0005] The aforementioned technology uses a metal film layer for radiation protection, but this results in a heavy fabric. The technology does not disclose a synthetic filament fabric that provides radiation protection, weight reduction, water resistance, and good thermal insulation. Therefore, a highly elastic radiation-protective fabric based on synthetic filaments that provides radiation protection, weight reduction, water resistance, and good thermal insulation is needed to solve this problem. Summary of the Invention
[0006] One objective of this application is to provide a highly elastic radiation-resistant fabric based on synthetic filaments and a method for preparing the same, which can solve the technical problems raised in the prior art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-elasticity anti-radiation fabric based on artificial filaments, wherein the high-elasticity anti-radiation fabric based on artificial filaments comprises, from bottom to top, a fabric layer one and a fabric layer two, wherein the fabric layer one is woven from modified artificial filaments, and wherein the modified artificial filaments comprise, from the inside to the outside, a filament body, a heat insulation layer and an anti-radiation layer.
[0008] Preferably, the second fabric layer is woven from rayon, which is one of polyester, nylon, and polypropylene.
[0009] Preferably, the filament body is one of polyester, nylon, and polypropylene.
[0010] Preferably, the insulation layer is a flexible foam plastic, which is formed by melt mixing 3-5 parts of foaming agent and 30-50 parts of polyvinyl chloride.
[0011] Preferably, the foaming agent is one of azodicarbonamide and diisopropyl azodicarbonate.
[0012] Preferably, the radiation shielding layer comprises 20-30 parts polyvinyl chloride, 10-15 parts metal powder, 10-15 parts graphene powder, and 20-30 parts solvent.
[0013] Preferably, the metal powder is one of copper powder, iron powder, and aluminum powder.
[0014] Preferably, the solvent is dichloromethane.
[0015] Preferably, the preparation method of the high-elasticity radiation-proof fabric based on synthetic filaments includes the following steps:
[0016] S1. Place the foaming agent and polyvinyl chloride granules into a stirring device equipped with a heating device and stir and heat them at a temperature of 180°C for 10 minutes.
[0017] S2. Place the polyvinyl chloride granules, metal powder and solvent into the stirring device II equipped with a heating device and stir and heat them at a temperature of 180°C for 10 minutes.
[0018] S3. Then, immerse the filament body in the stirring device two of step S1 for 3 minutes. After that, take out the filament body and cool it to form a heat insulation layer. After cooling for 10 minutes, continue to put it into the stirring device two of step S2 for 1 minute to form a radiation protection layer.
[0019] S4. Next, the filament body is taken out from the stirring device 2 and cooled for 10 minutes to form modified artificial filament. Then, the modified artificial filament is used to weave fabric layer 1 and artificial filament to weave fabric layer 2. Then, fabric layer 2 is bonded to the top of fabric layer 1 by gluing method to obtain a high-elasticity radiation-proof fabric based on artificial filament.
[0020] Preferably, step S2 further includes the following steps:
[0021] S21. Graphene powder, polyvinyl chloride particles, metal powder and solvent are simultaneously placed into stirring device two.
[0022] Compared with the prior art, the beneficial effects of the present invention are:
[0023] 1. This invention uses synthetic filament polyester, nylon and polypropylene as base fibers to give the fabric good elasticity. By adding metal powder and graphene powder to the radiation shielding layer, electromagnetic radiation can be effectively shielded. Furthermore, mixing metal powder and graphene powder with polyvinyl chloride can effectively reduce the loss rate of metal powder and graphene powder during washing.
[0024] 2. The present invention can effectively shield electromagnetic radiation by adding metal powder and graphene powder to the radiation shielding layer, and the addition of graphene powder can effectively reduce the overall weight of the fabric, thereby improving the comfort of people using the fabric.
[0025] 3. By setting an insulation layer on the outside of the filament body, the present invention can effectively increase the overall insulation performance of the fabric and reduce the poor insulation performance of the fabric caused by the addition of metal powder in the anti-radiation layer. Moreover, the insulation layer is inside the anti-radiation layer and does not easily absorb water, thereby reducing the weakening of the insulation capacity caused by water entering the insulation layer.
[0026] 4. By setting a second fabric layer and positioning the second fabric layer towards the dusty side, the present invention can reduce the adhesion of dust and impurities to the first fabric layer, thereby reducing the difficulty in cleaning caused by dust adhering to the first fabric layer.
