Problems solved by technology

This kind of woven fabric has the defects of large production process equipment, many manual links, small product width, thin thickness, loose structure, low tensile strength, and poor impact resistance. Due to its low strength, it is used as a false top net It often needs to be used in multiple layers (normally 4 layers), which is inconvenient to install and use, and the labor intensity of workers is high
And because the product material determines the defects of the raw material formula system, the existing woven fabric made of polypropylene particles produces more toxic components such as HCl and CO in the flue gas after combustion, which does not meet the current environmental protection and application safety concepts. The use is very limited, so it has not been widely promoted

Abstract

The invention relates to the technical field of a macromolecular material, in particular to fiber woven cloth and a preparing method of the fiber woven cloth. Coal mine underground halogen-free flame-retardant antistatic fiber woven cloth comprises a fiber woven cloth body, wherein when the fiber woven cloth body is woven by using halogen-free flame-retardant fiber industrial yarns with the fiber number range being 222 dtex to 5555 dtex, a conducting yarn is uniformly embedded and woven into a warp direction and/or a weft direction at equal intervals; and the yarns are directly woven into the halogen-free flame-retardant antistatic fiber woven cloth through a loom. The halogen-free flame-retardant fiber industrial yarns are made of halogen-free flame-retardant polymer slices with the phosphorus content being 5000 ppm to 8500 ppm. The fiber woven cloth and the preparing method have the obvious advantages that on the premise of ensuring the safety performance and the use performance, non-pollution discharge is achieved in the production process; artificial links are few in the production process; the automation degree is high; a product achieves halogen-free low-toxicity and environment-friendly effects; the weight is light; the installation is fast, convenient and efficient; and the use range is wide, and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a fiber woven cloth and a preparation method thereof. Background technique [0002] Plastic woven cloth is a product used as false roof net and side protection net during underground mining and work in coal mines. It is circularly woven or sewn into woven bags, and can also be used for landfill and sealing of goafs. At present, the woven cloth used in the underground is made of polypropylene particles, which are extruded and drawn into a flat wire by a wire drawing mechanism, and then woven into a cloth or bag through a loom, and then the cloth is dip-coated with a pre-configured flame-retardant and anti-static liquid, or for Polypropylene particles are mixed with flame retardant and antistatic materials to meet the application requirements of flame retardant and antistatic products. This kind of woven fabric has the defects of large production process equipment, many ...
