Definitions

  • the present invention relates to textile fabrics which a structure of fibers comprising, which by means of a polymer Binders are interconnected (nonwovens) and a Process for their production.
  • a structure of fibers is used to produce a nonwoven (Fleece), which is then solidified or glued.
  • the fibers can have a preferred direction or non-directional his.
  • Various processes are known for producing nonwovens, e.g. (1) the mechanical formation of fleece from staple fibers or filaments; (2) aerodynamic web formation from staple fibers or filaments; (3) hydrodynamic web formation from staple fibers or filaments and (4) electrostatic web formation Fine fibers or filaments.
  • the so obtained Nonwovens become nonwovens using different processes solidified.
  • Nonwovens are used for a large number of applications used. For example, nonwovens are increasingly as cleaning and Wipes, dishcloths and napkins used. In these applications it is important that e.g. spilled liquids, such as milk, coffee, etc., quickly and completely when wiping over soaked up and completely dried on damp surfaces become. The speed and completeness with which Liquids are sucked up, determine the usage properties of a cleaning and wiping cloth and are the main criteria for the goodness of the item.
  • a cleaning cloth absorbs liquids the quicker the faster their transport takes place on the fiber surface.
  • a hydrophilic The surface is easily and quickly wetted by water. The water spreads very quickly over the entire surface of the nonwoven and the water is "sucked away" from the contact point. hydrophobic In contrast, surfaces are not wetted. You run the Liquid therefore also no further and are for one use unsuitable as cleaning cloth or wipe.
  • Crucial for the crowd of liquid that can be absorbed is, among other things also the swelling behavior of the fiber.
  • a hydrophobic binder that largely envelops the fiber affects the kinetics of the Water intake.
  • nonwovens To improve the water absorption properties of nonwovens are sometimes surface-active hydrophilizing in their manufacture Agents such as emulsifiers, surfactants or wetting agents are used. This makes for excellent initial hydrophilicity reached.
  • these nonwovens have the disadvantage that the hydrophilic agents through water or other aqueous media be washed out gradually. After repeated contact with water the product becomes increasingly hydrophobic. The flushing, cleaning or Wipe thus loses its ability to wash soak up aqueous liquids quickly. The cloth will consequently unusable for further use, and must be disposed of be, although the mechanical strength of the cloth for further Cycles of use are still sufficient. This is with regard to one responsible handling of raw materials disadvantageous.
  • the present invention was therefore based on the object To provide hydrophilic fabrics, its hydrophilicity is retained even after repeated washing.
  • the present invention therefore relates to a textile fabric, which comprises a structure of fibers, which by means of a polymer Binder are interconnected, and characterized is that the fabric is an oxide and / or hydroxide of Al, B, Si, Mg, Ti and / or Zn in a colloidal dispersion and one selected from sulfosuccinates and sulfosuccinamates Contains wetting agents.
  • the present invention further relates to a method of manufacture of a textile fabric, in which a structure of Impregnated fibers with a dispersion of a polymeric binder, dried, and optionally hardened, the result is characterized in that the structure also (i) with a colloidal Suspension of an oxide and / or hydroxide of Al, B, Si, Mg, Ti and / or Zn is impregnated or with a solution Precursor of an oxide and / or hydroxide of Al, B, Si, Mg, Ti and / or Zn is impregnated and the formation of the oxide and / or Hydroxide is induced in a colloidally disperse distribution and (ii) the structure with one among sulfosuccinates and sulfosuccinamates selected wetting agent is impregnated.
  • the textile fabric according to the invention preferably contains 1 - 20% by weight, based on the dry weight of the polymeric binder, in particular 3-15% by weight and particularly preferably 5-15% by weight, oxide and / or hydroxide of Al, B, Si, Mg, Ti and / or Zn.
  • the textile fabric according to the invention preferably contains 1 - 20% by weight, based on the dry weight of the polymeric binder, in particular 2-10% by weight, wetting agent.

In general it is advisable to impregnate with the wetting agent to be carried out simultaneously with the impregnation of the binder. For this purpose, the wetting agent simply becomes the aqueous binder dispersion given.
  • Polyester cellulose fleeces (70PES / 30ZW; 1.7 dtex; fiber length 38 mm; 30 g / m 2 ) a length of 35 to 50 cm and a width of 25 to 28 cm were lengthways in an impregnation and suction system an endless PES sieve belt through a 25% binder liquor and over a suction device.

  • the belt speed was 1 to 2 m per min.
  • the wet application was set to approximately 160% via the adjustable strength of the suction, which corresponds to a dry application of approximately 40%.
  • the binder liquor contained the additives listed in the table below (% by weight, based on the dry weight of the binder).
  • the impregnated nonwovens were placed on the belt of a Mathis sieve belt dryer type TH, secured against slipping and dried at 150 ° C. for 2 minutes. The top of each fleece was marked and the quantity applied was determined by weighing.
  • the nonwovens thus obtained were immediately and after five times Wash subjected to a wetting test.
  • the colored Run test used for the quantitative determination of the hydrophilicity. This test basically works as follows ab: On the diagonally clamped nonwoven, a defined amount of colored water applied. Depending on the hydrophilicity the water runs off or penetrates more or less quickly into the nonwoven. Characteristic color spots, e.g. circular for quick penetration into the nonwoven or narrow and elongated for slow penetration and preferred Expire, get. The assessments are based on a grading scale assigned.
  • test specimen measuring 21 x 5 cm is clamped in a frame that describes an inclination of 30 degrees with respect to the horizontal.
  • the side at the top in the dryer faces down during this test.
  • 0.5 ml of test liquid is applied from a height of 10 mm and a distance from the upper fleece edge of 30 mm.
  • the test liquid consisted of 2 g of Hostapal CV solution, 2.5 g of Lurantin-Lightfast-Turquoise Blue-GL to 1 l of completely demineralized water. After the test specimen has dried (hanging), the top of the fleece is examined and a grade of 0 for no wetting (test liquid completely drained off) to 5 for total wetting is assigned.
  • Examples 4 and 10 a nonwoven fabric was obtained after 5 washes is hydrophilic. These examples contained a sulfosuccinic acid ester in connection with colloidal silica. Without silica (Example 2) is even when using the same emulsifier no permanent hydrophilicity obtained. Other emulsifiers (Examples 5, 6) do not lead to the desired permanent hydrophilicity. Also polymeric additives (example 8) or higher amounts of Silicic acid in the absence of sulfosuccinic acid esters (example 9) do not lead to the desired properties.
  • Standard cellulose nonwovens (Whatman # 4; 100% cellulose), 35 to 50 cm long and 25 to 28 cm wide, were pulled through a 10% binder liquor (Acronal DS 2350 X), squeezed and then in a Mathis stenter dryer with gauze.
  • the liquor contained the additives listed in the table below.
  • the nonwovens were first impregnated in the padding with a 5% Al 2 (SO 4 ) 3 solution, squeezed and dried and only then soaked in the padding with binder and dried again.
  • the nonwovens obtained were subjected to an absorbency test. For this purpose, a 5 times washed and dried fleece strip (70 x 30 mm) with an immersion depth of about 5 mm was hung in the test liquid (see above) and after 30 s the rise height was noted. The penetration rate in the nonwoven was also measured. For this purpose, 0.1 ml of test liquid was placed on the front of 5 times washed and dried nonwoven fabric samples and the time was noted until the drop completely penetrated the nonwoven fabric. The results are shown in the table below. Vers. No. mineral.
