Problems solved by technology

At present, flame-retardant cotton fabrics or aluminum-coated fabrics are generally used, but they have poor resistance to molten metal impact and poor wearing comfort.
With the rapid development of textile technology, a large number of high-performance fibers have emerged on the market, which has promoted the development of new products, such as aramid, flame-retardant viscose, acrylic and other blended products; although the above products have good resistance to molten metal Impact resistance, flame retardancy, and high temperature resistance, but the research and development of this type of product is basically still in the imitation stage, and the product quality is uneven, and there is no national product testing standard for molten metal splashing

Abstract

The invention discloses a molten metal splashing protection fabric. The molten metal splashing protection fabric is woven from warps and wefts; the warps and wefts are composed of 15-45% of wool fiber, 35-45% of flame-retardant viscose, 15-25% of aramid fiber, 5-10% of polyamide fiber and 0-5% of conductive fiber. A production method of the molten metal splashing protection fabric comprises performing processes of blending, warping, denting, weaving, burling and aftertreatment on the fiber materials to obtain the molten metal splashing protection fabric. The molten metal splashing protection fabric is high in flame retardance, heat resistance, thermal radiation resistance, slipping property and molten metal impact resistance.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a molten metal splash protection fabric, and also relates to a manufacturing method of the fabric. Background technique [0002] The process of smelting production is relatively complicated, and there are many hazards in the whole production process, including smoke, noise, high temperature radiation, splashing of molten metal and slag, explosion, blast furnace gas, blast furnace gas combustion explosion, coal powder explosion, etc. According to the statistics of accident data over the years, among them, the burning accidents are the most, and the specific manifestations are burns to the human body such as the overturning and falling of high-temperature metal liquid, the radiant heat of high-temperature metal liquid, the splashing and leakage of molten metal, etc.; and the main cause of burning accidents is The protective effect of personal protective equipment is to...
