Definitions

  • the present invention relates to a method for treating textile materials with a fluorocarbon resin, designed for application from aqueous systems, comprising precipitating from an aqueous emulsion or suspension containing the fluorocarbon resin, the resin by adding a ketone, such as acetone; separating the resin from the supernatant liquid; suspending or dissolving the resin in a chlorinated solvent; applying the so-prepared suspension or solution to a textile material; and, drying the fabric so as to maintain the organic fluorocarbon resin on the fabric to impart oil and water repellency.
  • a ketone such as acetone
  • a fluorocarbon such as described in US. Patents 2,841,573; 3,147,- 065; 3,147,066; 3,188,340; 3,198,754; 3,248,260; 3,256,- 230; 3,256,231; and 3,282,905; for example, in emulsified or dispersed systems as commercially available, is mixed with a sufiicient amount of a ketone, such as acetone, to precipitate the fluorocarbon resin.
  • a ketone such as acetone
  • the fluorocarbons are generally available in aqueous systems as emulsions or dispersions of the following composition:
  • test specimen should be conditioned for a minimum of four hours at 7012" F. (21:1 C.) ad 65i2% RH prior to testing.
  • test liquid AATCC Oil Repellency Rating No, l
  • a small drop approximately V in. (5 mm.) diameter or 0.05 ml. volume
  • the dropping bottle pipette on the test specimen in several locations. Observe the drop for 30 seconds, from approximately a 45 angle.
  • AATCC Oil Repellency Rating of a fabric is the highest-numbered test liquid which will not Wet the fabric within a period of 30 seconds. Wetting of the fabric is normally evidenced by a darkening of the fabric at the liquid-fabric interface. On black or dark shades, wetting can be detected by loss of sparkle within the drop.
  • Standard Spray Test (Federal Specification CCC-T- 191b, Method 5526; AATCC Standard Test Method 22-1952).
  • Drops of fluid hydrocarbons of varying surface tension are placed, without impact, on the fabric surface and the extent of surface wetting is determined visually.
  • the oil repellency rating numbers were chosen to correspond with the AATCC Standard Spray Ratings which were in use prior to AATCC 118-1967(t) for testing water repellent finishes.
  • the Nujol-heptane proportions for each rating were selected so as to give oily stain resistance somewhat comparable to the water-borne stain resistance corresponding to each of the Standard Spray Test Ratings.
  • EXAMPLE 1 Two liters of an aqueous emulsion of a commercial stain repellent containing ca. 28% by weight of an organic fluorocarbon resin (analytically determined to be predominantly 1,1,2 trichloro 1,2,2 trifluoro-ethane), 8% ethylene glycol, 12% acetone, and the balance water, was mixed with 2 liters of acetone. An off-white pricipitate formed, was allowed to settle, the supernatant liquor decanted and the precipitate taken up in sufficient stabilized 1,1,1-trichloroethane to yield a 28% solids solution.
  • an organic fluorocarbon resin analytically determined to be predominantly 1,1,2 trichloro 1,2,2 trifluoro-ethane
  • This solution was further diluted with 1,1,l-trichloroethane to provide a 4.3% solution of fluorocarbon resin concentrate in 1,1,1-trichloroethane, and employed to treat a 14 ounce wool fabric, a tricot and an 11 ounce rayon-acetate blend fabric by spraying the solution onto the fabric under a pressure of 12 p.s.i. while moving the fabric through the spray zone at a rate of 22 yards per minute.
  • the employment of a 4.3% solution of the concentrate will provide a deposition of 0.3 percent solids by weight of fabric.
  • the so-treated fabrics were dried. In this manner, the major portion of the chlorinated hydrocarbon solvent was removed leaving the fluorocarbon resin on the fabric.
  • the standard test for oil and stain repellancy was run. The face of each fabric treated was found to have an oil repellency rating of 5. AATCC 118-1966T.
  • EXAMPLE 2 In a similar manner as set forth in Example 1, 3 gallons of solution were prepared. A 14-16 ounce upholstery fabric was treated with the solution by spraying the solution onto the fabric from 15 nozzles under 25 p.s.i. pressure at a line speed of 13 yds/min, to impart a calculated 0.3% solids on fabric. The so-sprayed fabric was dried, then tested for oil repellency. The face of the fabric exhibited a rating of on the oil test.
  • EXAMPLE 3 In order to compare the results obtained by the technique of the present commercial solvent based solution treating agent containing fluorocarbon in 1,1,l-trichloroethane and stabilizers was diluted to a concentration to provide a calculated 0.3% fluorocarbon solids deposition on the fabric when applied under a controlled condition. In the instant case, the solution was sprayed onto the same fabric (as in Example 2) at yds./min. under 15 p.s.i. pressure from 15 nozzles. The fabric after drying rated 5 on oil repellency.
  • Fabric weight Rating fabric face 1 1 Oil repellency test.
