Definitions

  • the present invention relates to molten metal splash protective fabrics.
  • Ferrous/non-ferrous metals and their alloys such as steel, stainless steel etc.
  • the aforementioned metals in their molten state with such high temperatures splash on a garment, the garment gets immediately destructed.
  • the splashes of molten ferrous metals, such as iron, or non-ferrous metals, such as aluminium, copper, zinc, lead, tin, nickel, and magnesium, and their alloys adhere to the protective fabrics. Due to the hot stuck metal, there is immediate heat transfer between the hot metal and a person wearing the protective fabric and also immediate destruction of the fabric.
  • Aluminium the most common non-ferrous alloy, is known for its easy“staying stuck” behavior in the clothes of wearers, typically smelters.
  • Molten aluminium has an operating temperature of 7000° Celsius to 8000° Celsius, which is enough to cause severe bums to the smelters.
  • Conventional protective garments are made of a fabric having a blend of flame- retardant fibers and wool for protection against ferrous metals and nonferrous metals, mainly aluminium.
  • Such protective fabrics must withstand high thermal shocks and hot molten metal splashes to avoid being destroyed, and at the same time, maintain the structure thereof so as to prevent hot metal from entering into the wearer’s clothing.
  • ISO 11612:2015 is one of the codes specified by the ISO for protective clothing. It is observed that the conventional fabric, having a blend of flame-retardant fibers and wool, passes ⁇ ” code of ISO 11612 which is for iron. However, the fabric fails to comply with requirements of ISO 11612“D” Code which is for aluminium. Molten iron is not as viscous as molten aluminium. Thus, conventional fabrics pass“E” code but fails in“D” code. Further, due to use of wool, the yams of such protective fabric require use of particular spinning system for their manufacturing. Typically, a worsted spinning system is used to manufacture yams of aforementioned conventional protective fabrics.
  • the present invention relates to a molten metal splash protective fabric.
  • the fabric consists of an intimate blend of vinyl on fibers ranging from 80% to 90% w/w of the fabric and cellulosic fibers ranging from 10% to 20% w/w of the fabric.
  • the vinylon fibers range from 85% to 90% w/w of the fabric and cellulosic fibers ranging from 10% to 15% w/w of the fabric.
  • the cellulosic fibers are selected from the group consisting of cotton, tencel, and excel.
  • the fabric is a textile woven fabric, preferably twill woven fabric.
  • the fabric is made of a plurality of double yams, and has weight ranging from 280 to 400 grams per square meter.
