Description

TECHNICAL FIELD [0001] The present invention relates to electrostatic conducting and light reflecting fabrics, electrostatic conducting and light reflecting fabrics,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of manufacturing light reflecting materials, and more particularly, to electrostatic conducting and light reflecting fabrics and a manufacturing method thereof.

The scientific term for light reflective fabrics is retro reflective fabric. This is a fabric that most of the reflected light returns to the direction of the light source in accordance with the direction of the incident light by using the optical principle that the glass bead is fixed to the fabric by using an adhesive and the light is refracted in the glass bead and then reflected again. These fabrics are safety functional fabric products with safety functions and are used as outdoor workwear for outdoor workers in special industries such as traffic, environmental hygiene and security. Generally, it is sewn in a belt-shaped safety garment to show safety warning effect through remarkable reflection effect at night. High-visibility safety clothing can be worn by outdoor workers of various industries, and its application range is very wide. If a person working in the night or in the dark wears or wears such a safety material, it will have an effect of making it easily visible by the retroreflective function when the light is irradiated. Therefore, the visibility of the worker 's own person is raised, so that the light source personnel can easily find the target, thereby effectively preventing the occurrence of accidents and ensuring personal safety. At present, overseas famous sporting goods and leisure goods companies are aiming at lifestyle where outdoor salaried men living in the city use outdoor activities in the morning and evening, And the like, thereby realizing the beauty and practicality of the garment while providing a safety function. At the same time, applying light reflective materials to clothing is a trend of international clothing fashion and is an implementation of fashion and luxurious features. In such applications, the anti-static performance of light reflecting fabric products is not required. However, for example, in a working environment that is prone to combustion and explosion, such as chemical industry, coal gas, petroleum, coal mine, marine transportation, These products can not be used because they tend to generate static electricity. Currently, many antistatic fabrics are already on the market, but there are relatively few light reflective fabric products that can prevent static electricity.

The present invention overcomes the shortcomings of the prior art and provides an electrostatic and light reflective fabric which is excellent in light reflection performance and has an effect of antistatic performance and can be applied to the protective clothing worn by the workers of industry who have the risk of static electricity.
