Definitions

  • An object of this invention is to provide a method by which the nap or raised surface of synthetic fabrics are stabilized under normal laundering conditions.
  • Another object of this invention is to provide a stabilizing agent to prevent excess pilling and shedding of the nap or raised surface of synthetic fabrics.
  • Another object of this invention is to provide a stabilizing agent for the nap or raised surface of synthetic fabrics which gives a soft hand.
  • Another object of this invention is to provide a stabiliz ing agent for the nap or raised surface of synthetic fabrics which does not deleteriously affect the color.
  • Another object of this invention is to provide a stabilizing agent for the nap or raised surface of acrylic fabrics which render same free of excessive pilling and shedding under normal laundering and wearing conditions.
  • Another object of this invention is to provide permanent stability in high pile fabrics against matting, pilling and shedding.
  • the objects of this invention are generally accomplished by applying an aqueous solution of aniline or an inorganic salt of aniline to the nap or raised surface of synthetic fabrics either woven, non-woven or knitted.
  • Aniline is applied by the conventional padding or spraying method.
  • other agents may be used in conjunction with the stabilizing agent to impart other desirable properties to the fabrics.
  • Some agents such as Aston 108, which is a polyarnine resin such as diethylenetriamine crossed linked with polyethylene glycol diiodide or an epoxy resin, more fully described in US.
  • Patent 2,982,751 which is an anti-static agent may be used in conjunction with the stabilizing agent of this invention as well as a Water repellent agent such as Phobotex, F.T.C., a melamine derivative, which will not affect the hand or color, but will give excellent resistance to water penetration and absorption.
  • Phobotex F.T.C.
  • a melamine derivative which will not affect the hand or color, but will give excellent resistance to water penetration and absorption.
  • These and other additives for specific end uses may be used in conjunction with the agents of this ice invention without affecting the hand and color of the fabrics.
  • the synthetic fabrics were napped and then treated with an aqueous solution of aniline in the range of 0.05 percent solution to a 50 percent solution with the preferred solution being a 0.5 percent to a 2.0 percent solution.
  • the aniline is first dissolved in an organic alcohol such as ethanol, methanol, butanol, propanol, etc, and then dissolved in water.
  • the alcohol aids in dissolving the aniline. This dissolving in alcohol permits a more even and thorough distribution of the stabilizing agent over the surface of the trapped fabric. If the salts of aniline, such as aniline acetate, aniline hydrochloride and aniline sulfate are used then there is no need for the alcohol as these salts are completely soluble in water.
  • This curing results in concentrating the stabilizing agent at the intersections of the fibers in the nap to form a durable bond between and among themselves.
  • the period of time the fabrics were heated varied from v5 minutes to 60 minutes, with the preferred time being 20 minutes, at a temperature of from 240 F. to 300' F. with the preferred temperature being 280 F. If an aqueous solution of the stabilizing compound is used alone, then the exact temperature is immaterial as long as the fabrics so treated are dried; however, the temperature must not go to the degradation point of the acrylic fibers, 350 F.
  • the napped fabrics were then withdrawn from the drying apparatus, and it was found that the hand was of acceptable softness and the color was unaffected.
  • the stabilizing compound and other agents, if used, were added onto the nap by the conventional padding method and spraying method which is well known in the textile field.

  • Example 1 A swatch of napped fabric composed of fibers of 94 percent acrylonitrile and 6 percent vinyl acetate was padded with a 1 percent aqueous solution of aniline dissolved in methanol. The swatch was then placed in a drying oven and heated for 10 minutes at 280 F. It was then removed and allowed to cool, after which the swatch was laundered five consecutive times under normal laundering conditions and dried. There was no appreciable change in the soft hand which would affect its commercial acceptability and the color remained unchanged. In addition there was no excessive amount of matting, pilling or shedding.
  • Example 2 The exact method of Example 1 was followed except 4- a 3 percent aqueous solution of aniline dissolved in methanol was used. The results after the washings were the same.

The swatch was then placed in a drying oven and heated for 15 minutes at 220 F. and then the temperature was raised to 280 F. and held there for 10 minutes. The swatch had a very soft and pleasant hand which resisted ten consecutive launderings under normal laundering conditions. No pilling, matting or shedding was observed on the washed swatch.
  • Example 6 A swatch of napped fabric composed of fibers of 94 percent acrylonitrile and 6 percent vinyl acetate was padded with a 2 percent aqueous solution of aniline in methanol and 1 percent Nalcsay 1050 which is a colloidal silica in water. The swatch was then placed in a drying oven and heated for 15 minutes at 220 F. for drying and then cured by heating for 10 minutes at 280 F. It was then removed and allowed to cool, after which the swatch was laundered for five consecutive times under normal laundering conditions and dried. The hand remained soft and the color was unchanged. In addition, there was no excessive amount of matting, pilling or shedding.
