Definitions

  • fluorocarbon resins preferably in the form of non-ionic emulsion of such resin.
  • fluorocarbon resin includes any fluor-containing organic compound which has been used already for oleophobizing textile material.
  • the production of these fluor-containing 3,411,315 Patented Oct, 7, 1969 ice organic compounds is well known in the art. Reference is made only to US. Patents 2,662,835, 2,642,416, 2,592,- 069, British Patent 759,356, Austrian Patent 209,309 or German Auslegeschrift 1,182,630.
  • fabrics are generally oleophobized with fluorocarbon resins in such amounts that a weight increase of 6% results, quantities of as little as 0.25% sufiice in the present case.
  • the preferable amount will be 0.5 to 3%. Larger amounts will be detrimental because the adhesive will then not stick firmly to the base fabric.
  • the oleophobizing effect is no longer present, so that the prevention of the penetration of the adhesive coating cannot be ascribed to the oleophobizing effect. It is more probable that the oleophobizing agents bring about an immediate coagulation of the polyamide or other adhesive from the solution. This coagulation occurs in the instant in which a polyamide droplet encounters the oleophobized surface of the interlining. The immediately coagulated polyamide then remains adhering to the surface.
  • a similar effect occurs also when the polyamide solution is sprayed onto wet or moist goods because, as it is known, water has a coagulating effect on polyamide solutions. However, this efiect is not to be compared with that which occurs when they are sprayed onto oleophobized material.
  • the oleophobizing agent produces a much more pronounced effect than water.
  • a fiber bat consisting of 50% polyamide fibers (3 deniers) and 50% staple rayon (3 deniers) and having a weight of 35 grams per square meter, is bonded with an acrylic resin dispersion (Acronal 30-D, a product of BASF) in such a manner that, after drying, it weighs 70 g. per m
  • This fleece cloth is saturated with a mixture consisting of 0.25% liquid Scotchgard Oleophobol P-68 in tap water, squeezed out to 100% wet absorption, and dried at 120 C.
  • Weight-parts Soluble polyamide (Ultramid 6-A, product of BASF) 32 p-Oxybenzoic acid derivative (plasticizer for the polyamide) Methyl alcohol (solvent) 70 Methylene chloride (solvent) 30 is sprayed, and is dried at approximately C. The resulting product has a coating that is entirely on the surface of the fleece cloth.
  • a fiber bat, consisting of 70% polyester fibers (Dacron) (2.5 deniers), 20% Zellwolle (3 deniers), and 10% wool, having a weight of 40 g. per m. is impregnated in two steps in a manner as described in US. Patent 2,719,806 with a latex (Perbunan N, a product of Wegriken Bayer). After drying, the final product weighs 65 g. per m.
  • This product is subsequently impregnated with a mixture consisting of 0.5% of a fluorocarbon resin as made according to German Auslegeschrift 1,182,630 in water, squeezed out to wet pick up of and dried at C.
  • a fluorocarbon resin as made according to German Auslegeschrift 1,182,630 in water
  • FIG. 1 is a perspective view of a fabric according to the invention.
  • FIG. 2 is a side elevation, greatly enlarged.
  • the fabric 1 includes the body portion 2, which can be and preferably is a nonwoven fleece, and the coating 3, which coats the fibers of the fabric making up the upper surface of the fabric.
  • the fabric is impregnated with the oleophobizing agent, and the adhesive is deposited on the surface, while the body portion of the fabric is substantially free of the adhesive. If desired, both of the surfaces of the fabric can be provided with an adhesive coating according to the invention.
  • the invention provides an improvement in the process for application of adhesive coating to a fabric surface wherein the adhesive dissolved in a solvent is deposited on the fabric and the fabric carrying the adhesive solution is dried to expel the solvent and deposit the adhesive on the fabric.
  • the fabric is preferably a non-woven fleece, though it can be in another form such as a woven fabric.
  • the solvent in which the adhesive is dissolved can be any of the known solvents for such service, and the amount of adhesive present in the solvent can be the conventional amount.
  • the improvement of the invention involves applying to the surface of the fabric to which the adhesive is to be applied, an oleophobizing agent in an amount suflicient to coagulate the adhesive upon deposit of the solution thereof on the fabric, prior to substantial penetration of the solution to within the fabric.
  • the fabric is impregnated with the oleophobizing agent in an amount of a fraction of 1% of the weight of the fabric.
  • the solution containing the adhesive can then be deposited on the oleophobizing surface, whereupon coagulation occurs and the adhesive is deposited on the surface, without substantially penetrating the fabric.
  • the improvement which comprises applying to the surface of the fleece to which the adhesive is to be applied, an oleophobizing agent comprising the group of non-ionic fluoro-carbon resins in an amount of 0.5 to 5% by weight, based upon the weight of the fleece, and depositing the solvent containing the adhesive on said surface, said oleophobizing agent causing adhesive to be deposited from the solvent on said surface and preventtng penetration of adhesive to below the surface of the fleece.
