Definitions

  • the invention relates to a process for the production of consolidated nonwovens for the absorption of water and / or substances with oleophilic and / or lipophilic properties by blow spinning a melt or a solution of a spinnable polymeric material with the aid of a nozzle head which has one nozzle opening or several nozzle openings. to staple fibers and / or filaments, forming these staple fibers and / or filaments into a fleece by placing them on a receiving device, solidifying this fleece and applying a wetting agent to the fleece.
  • the invention also relates to consolidated nonwovens for the absorption of water and / or substances with oleophilic and / or lipophilic properties.
  • the embodiment according to claim 4 offers the advantage that the nonwovens obtained have a very large effective surface for the absorption of water and / or substances with oleophilic and because of the fineness of the staple fibers and filaments, that is because of their small diameter and thus high specific surface area / or have lipophilic properties.
  • the embodiment according to claim 5 offers the advantage that the surfactants used are biodegradable and very well tolerated by the skin.
  • the embodiment according to claim 6 offers the advantage that the surfactants used can solve special tasks, for example in metal treatment, where corrosion protection and rapid drying are important.
  • spinnable polymeric materials include polyesters, such as polyethylene terephthalate, and polyamides, such as polyamide-66, but also, for example, polyolefins, such as polyethylene and polypropylene, cellulose esters, such as cellulose-2,5-acetate and triacetate, and acrylic polymers, such as polyacrylonitrile.
  • polyesters such as polyethylene terephthalate
  • polyamides such as polyamide-66
  • polyolefins such as polyethylene and polypropylene
  • cellulose esters such as cellulose-2,5-acetate and triacetate
  • acrylic polymers such as polyacrylonitrile
  • a melt or a solution of a spinnable polymeric material is blow-spun into staple fibers and / or filaments.
  • Such blow-spinning is described, for example, in "Industrial and Engineering Chemistry", volume 48, no. 8 (1956), pages 1342 to 1346, and in German Patent 19 64 060.
  • Substances with oleophilic and / or lipophilic properties are e.g. Oils, such as mineral oils or silicone oils, and fats or mixtures thereof.
  • a zwitterionic or a cationic surfactant is applied to the nonwoven as a wetting agent.
  • Suitable zwitterionic surfactants are in particular amine oxides and betaines, but also imidazoline carboxylates and aminocarboxylic acids.
  • Suitable cationic surfactants are, for example, primary, secondary, tertiary or quaternary ammonium salts, benzylammonium salts, alkanolammonium salts, pyridinium salts, imidazolinium salts, oxazolinium salts, thiazolinium salts, sulfonium salts, quinolium salts, salts of amine oxides, tropinium salts and isochlorine salts. If necessary, mixtures of the same can also be used.
  • the nonwovens according to the invention can be used, for example, as roll goods or in pieces adapted therefrom in industrial or non-industrial areas for cleaning purposes; it is essential that both water and substances with oleophilic and / or lipophilic properties can be absorbed by the nonwovens.
  • Polyethylene terephthalate with an intrinsic viscosity of 0.67 (measured in tetrachloroethane phenol 1: 1), a melt viscosity of 2,400 dPa.s and a water content of 0.1 percent by weight was melted at 323 ° C and using a spinning head (nozzle head) similar to that according to German Patent 25 50 463 to staple fibers and filaments, the one had an average diameter of 1.8 ⁇ m, melt-blow-spun.
  • the staple fibers and filaments were formed into a nonwoven with a basis weight of 100 g / m 2 by being placed on a holding device which consisted of a rotating drum. The nozzle head was above the rotating drum and it was spun vertically downwards.
  • the fleece which had a width of 200 mm, was guided over guide rollers onto a continuous endless sieve belt, which was part of a water jet consolidation device, which in principle corresponded to that in accordance with German patent specification 16 35 577.
  • the water jet consolidation device had eight rows of water nozzles, which were arranged above the fleece and at an angle of 90 ° to the running direction of the fleece. Each row of water nozzles had a length (effective jet width) of 200 mm and each had 100 nozzle bores. The distance between the nozzles and the fleece was 10 mm and there was a water pressure of 120 bar in front of each nozzle. The water jets formed an angle of 90 ° with the fleece.
  • the process water was then removed to a residual moisture content of the fleece of 100% by subsequently passing the fleece through squeeze rolls.
  • the wetting agent was applied by passing the fleece over a structured net roll.
  • the wetting agent was 1-alkoylamino-3-dimethylamino-propane-3-N-oxide.
  • the wet absorption (liquid absorption) of the fleece was 100% of the initial dry weight of this fleece.
  • the wetting agent bath had a concentration of 0.5 weight percent of the aforementioned wetting agent; this gave the fleece a content of 0.5% by weight of wetting agent, based on the dry weight of the fleece.
  • the fleece was guided from the netting roller through a drying oven, where it was dried to a residual moisture content of approximately 1%, and then wound onto tubes.
  • the process speed that is to say the speed at which the nonwoven ran continuously through the process steps mentioned, was 2 m / min.
  • the solidified nonwoven obtained had a maximum tensile force (measured according to DIN 53857) in the longitudinal direction of 8.3 daN and in the transverse direction of 4.5 daN.
  • the specific spun fiber / filament surface of this fleece effective for the absorption of water and / or oils and / or fats and the like was 1.6 m2 / g (measured according to the BET method), corresponding to 160 m2 surface per m2 fleece.
  • the oil absorption capacity of this fleece (measured according to the oil binding directive of the Federal Ministry of the Interior in the version of December 31, 1985) was 4.3 g of oil per g of fleece.
  • the water absorption capacity of this fleece was 5.8 g of water per g of fleece.
  • the solidified nonwoven obtained had a pleasant soft textile feel and a good fall.
