Definitions

  • Activated carbon is used in particular as granules for a wide variety of purposes, e.g. B. systems for the recovery of solvent vapors, filter systems for decolorizing liquids, for odor filters in extractor hoods, medical applications, gas mask filters, ABC protective suits etc. used.
  • activated carbon is particularly effective because of the favorable surface to volume ratio, which improves the accessibility of the pores.
  • These activated carbon fabrics or nonwovens are made by carbonizing fabrics or nonwovens made from carbonaceous materials and then activated with water vapor, but never by processing individual carbon fibers.
  • the advantage of the high adsorption capacity of such surface filters is offset by the disadvantage of only very limited mechanical resistance. For this reason, they may be suitable for stationary systems, but not, for example, for protective suits against chemical warfare agents.
  • the invention has for its object to combine the advantages of activated carbon fiber with the mechanical strength of a fabric made of non-carbonized fibers. This was achieved by a blended yarn which consists of 5 to 75, in particular 20 to 40, percent by weight of activated carbon staple fibers and, moreover, textile staple fibers, and by fabrics made from this blended yarn.
  • the blended yarn according to the invention is produced by cutting a known cable made of activated carbon individual filaments into staple fibers, gently mixing them with textile staple fibers and spinning them.
  • the activated carbon staple fibers advantageously have a length of 1 to 10 cm. So that these staple fibers do not break when they are mixed with the other textile fibers used to produce the blended yarn, but rather remain in the specified length, the activated carbon staple fibers are expediently mixed with the other staple fibers of comparable length in a carrier liquid, in particular water or an aqueous liquid . It is best to drop the activated carbon staple fibers into a bath into which the textile individual fibers are simultaneously inserted after being cut off from a cable, which usually consists of 10,000 to several 100,000 individual filaments. Additional measures for mixing the staple fibers can then be taken in the liquid medium, but in many cases sufficient mixing of the various staple fibers is already achieved when the carrier liquid is separated off and then spun into the blended yarn.
  • the textile fibers which are to be spun into mixed yarns with the activated carbon staple fibers can be a wide variety of natural or synthetic, organic or inorganic fibers, such as cotton, wool, silk, polyester, polyamide or aramid fibers, Trade glass fibers or other mineral fibers. Polyamide-polyester or aramid fibers are preferred for the production of the blended yarns according to the invention.
  • the textile staple fibers of the blended fabric can consist of a flame-resistant synthetic polymer or be made flame-resistant.
  • the activated carbon staple fibers generally have a titer of 0.5 to 20, in particular 1 to 5 dtex.
  • the titer of the textile fibers is usually of the same order of magnitude.
  • the mixture of the activated carbon staple fibers with the textile staple fibers can be spun into mixed yarns in a known manner, and these in turn can be woven well.
  • the mixed yarn containing the activated carbon staple fiber can be used either only in the weft, only in the warp or both in warp and weft, depending on the application of the fabric. If a purely textile yarn is used for warp or weft, it does not have to be made of the same material as the staple fibers of the mixed yarn, but can be adapted to the particular use of the fabric.
  • the fabrics according to the invention made of mixed yarn containing activated carbon staple fibers can fully develop their filtering effect
  • the fabrics advantageously have an air permeability of 10 to 1,000, in particular 150 to 300 l / min - 100 cm 2 at 1 mbar negative pressure.
  • the air permeability can be achieved by weaving a loose yarn, which can then also be tightly knotted or by an open fabric.
  • the fabric should have a tensile strength of 100 to 20,000, in particular 200 to 2,000 Newton / 5 cm, which can be achieved both by the choice of sufficient tear-resistant staple fibers for the blended yarn and by the interweaving of very tear-resistant yarns.
  • the basis weight of the blended fabrics can range from 50 to 1,500 g / m 2 , for most applications a basis weight of 200 to 400 g / m 2 is preferred.
  • the fabrics according to the invention are distinguished by excellent textile properties, good strength and an adsorption activity which, based on the amount of activated carbon fiber used, is not inferior to fabrics made from pure activated carbon fibers.
  • the fabrics according to the invention from the mixed yarns containing activated carbon staple fibers are preferably used for surface filters. Here they are because of their better ones
  • the good textile properties and strengths of the fabrics according to the invention also enable them to be used to produce protective suits, in particular those for commercial or military purposes, i.e. to protect against chemicals or chemical warfare agents. example
  • Preoxidized polyacrylonitrile fibers of 1.5 dtex were carbonized in a known manner as a cable with 320,000 individual filaments and then activated with steam in a suitable oven.
  • a cable of activated carbon fibers with good mechanical properties and a BET surface area measured with nitrogen of 350 m 2 / g was thus obtained.
  • cellulosic fibers were carbonized and activated. Its BET surface area, measured with nitrogen, was 1,100 m 2 / g. Although the high activity comes at the expense of mechanical strength, it nevertheless permits the further processing into the mixed yarn described below or the subsequent weaving.
  • Staple fibers of 3 cm in length were cut from the cables of the activated carbon fibers. A part by weight of these activated carbon staple fibers was mixed in water with 2 parts by weight of a polyester staple fiber, likewise 3 cm in length and 1 dtex, and then spun. Blended yarns of about 70 dtex were obtained, and fabrics with a basis weight of about 280 g / m 2 were produced therefrom, the mechanical properties of which correspond to those of the same type of polyester blended fabric with wool or rayon. The activity of the activated carbon fibers was not influenced by the spinning to the blended yarn and weaving to the blended fabric.
