Description

Technical Field

[0001] The invention belongs to the technical field of fabric manufacturing, in particular to a nuclear radiation shielding fabric and a manufacturing method thereof. Background Art

[0002] The application of radiation in many fields such as science, medicine, geology, etc. is increasing. In its actual use, a certain amount of radiation will inevitably be generated. When the human body is exposed to more than a certain amount of radiation, it will cause radiation damage. In addition, radiation may pollute the environment. Inappropriate discharge of radioactive waste will have a bad impact on local water resources and crops, thus affecting human life and health. According to relevant national regulations, in order to reduce the damage of radiation to the human body, equipment, environment, etc., radiation must be effectively shielded. The study of radiation protection materials has also become an important direction of material research. However, with the further development of radiation devices and nuclear technology applications, traditional and single shielding materials can no longer meet the protection requirements of mobile reactors and portable radiation sources. For example, after a nuclear accident, the safety of nuclear energy has received widespread attention from the society. In order to overcome the challenges brought about by this, it is of great significance to develop new radiation protection materials that are lightweight, efficient, non-toxic, have excellent physical properties, good shielding effect, long-lasting performance, and easy to industrialize.

[0003] In addition, in the prior art, the fabric is generally rolled into a tube before dyeing for ease of operation. For such tubular fabrics, a common dyeing method is to pull the fabric directly into the dye vat, and then use a traction mechanism to complete the winding and pulling out of the dyed fabric. However, for fabrics that have not been pre-rolled into a tube, the traditional dyeing method is often to directly place the fabric loosely in the dye vat for dyeing. A significant drawback of this approach is that the fabrics are easily stacked on each other in the dye vat. This uneven distribution not only reduces the uniformity and efficiency of dyeing, but also brings inconvenience to the operation process, affecting the overall production flexibility and quality stability. Summary of the invention

[0004] The present invention aims to solve the technical problems existing in the prior art; to this end, the present invention proposes a nuclear radiation shielding fabric and a manufacturing method thereof.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A nuclear radiation shielding fabric and a manufacturing method thereof, comprising the following steps:

[0007] Step 1: Sizing, warping and weaving the fiber yarn containing the functional powder into grey cloth.

[0008] Step 2: The grey fabric is washed with water to remove oil and desize, soaked to soften, dyed in a dye vat, dried out of the vat, and stretched to shape to obtain the finished fabric.

[0010] The first fixed plate and the second fixed plate are both provided with a rotatable turntable, the turntable is rotatably connected to a connecting arm with an adjustable angle, the connecting arm is fixedly connected to a swing arm, and the swing arm is used to flatten the grey cloth.

[0011] As a further solution of the present invention: an electric cylinder is fixedly connected to the first fixed plate, and an output end of the electric cylinder is fixedly connected to a vertical plate.

[0014] As a further solution of the present invention: the top of the first fixed plate is fixedly connected with a support frame 1 and a support frame 2, and two guide rollers 1 are rotatably connected between the support frame 1 and the support frame 2, and two baffles with adjustable positions are arranged on the two guide rollers 1.

[0015] As a further solution of the present invention: two bending frames are fixedly connected to the bottom of the second fixed plate, and a guide roller 2 is rotatably connected between the two bending frames.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This application is different from the anti-electromagnetic radiation fabrics currently available on the market and the anti-radiation lead-containing rubber materials used in medical applications.

The fabric has the characteristics of being light, non-toxic, having excellent physical properties, having good shielding effect and lasting performance, and being easy to industrialize.
