Abstract

The invention relates to a halogen-free flame-retardant environment-friendly covered polyolefin yarn fabric and a preparation method thereof. The fabric is formed by weaving covered threads and has warp and weft structures; the covered threads comprise polyester fibers and halogen-free flame-retardant environment-friendly polyolefin composite materials covering the surfaces of the polyester fibers; the covered threads are 0.3-0.4 millimeter in diameter, rectangular or square gaps are reserved between the warp structures and the weft structures, and the aperture ratio is 2 to 10 percent; the halogen-free flame-retardant environment-friendly covered polyolefin yarn fabric is 0.55-0.75mm in total thickness and 350-420g/m<2>. The invention also provides a preparation method for the fabric. The fabric has the characteristics of sunshading, ultraviolet resistance, flame retardancy, high color fastness and the like of similar PVC (polyvinyl chloride) substrate fabrics, and also has the advantages of no halogen, environment friendliness, low smoke density during combustion, high self-cleaning property, high chemical stability, light weight, high air permeability and the like.

Description

technical field [0001] The invention relates to a fabric, in particular to a halogen-free flame-retardant and environment-friendly polyolefin coated yarn fabric and a preparation method thereof. Background technique [0002] Covered yarn fabric is a kind of fabric obtained by weaving fiber threads obtained by covering the surface of fibers (polyester, polypropylene, glass fiber, etc.) with plastic. At present, most of the fiber threads used in traditional covered yarn fabrics on the market are polyvinyl chloride (PVC) coated polyester fibers, which are mainly used in the building sunshade industry. PVC is a widely used general-purpose high-halogen polymer plastic with excellent processing performance. Its high halogen content makes it have good flame retardant performance, but its harm to the environment is also huge: halogen is soluble in water, in the air Combining with water vapor in the medium will form acid rain; in the process of injection molding or high temperature ...
