Definitions

  • This invention is concerned with the treatment of the raised surface of woven, non-woven and knitted synthetic fabrics to prevent distortion of the raised surface due to normal wearing and laundering conditions. More specifically, this invention is concerned with preventing the matting, shedding and pilling of the nap of acrylic fabrics, as well as preserving a soft hand, after subjecting these fabrics to normal laundering and wearing conditions.
  • An object of this invention is to provide a method by which the nap of synthetic fabrics are stabilized against ing composition for the nap of acrylonitrile fabrics which renders the fabricsfree of excessive matting, pilling and shedding under normal laundering conditions and normal wearing conditions as well as preserving a soft hand.
  • Another object of ttu's invention is to provide permanent stability of high pile fabrics against matting, pilling, shedding.
  • the objects of this invention are generally accomplished by applying an aqueous solution of ethylene carbonate and a coplymer of ethyl acrylate and methyl methacrylate to the nap or raised surface of synthetic fabrics, either woven, non-woven or knitted.
  • This composition may be applied by spraying, fogging or padding.
  • Other agents may be added on the fabrics during this operation such as an anti-static agent of Aston 108 which is a polyamine resin such as diethylene-triamine crossed linked with polyethylene glycol diiodide or an epoxy resin and a water repellent agent such as Phobotex F.T.C., a melamine derivative. These agents will not affect the hand or color of the fabrics but do give additional useful properties.
  • the synthetic fabrics either woven, non woven or knitted, were napped and then treated with an aqueous solution of ethylene carbonate and a copolymer of ethyl acrylate and methyl methacrylate.
  • ethylene carbonate and the 3,152,919 Fatented Get. 13, 1964 copolymer vary in a ratio of 1 to 1, 2 to 1 and 1 to 2 based on the weight of the aqueous solution with the preferred ratio being 1 part of ethylene carbonate to 1 par-t of the copolymer.
  • the napped and treated fabrics were then heated in a conventional drying apparatus, such as a chain dryer or an oven, to evaporate any water and to cure the copolymer; in addition, during this heating step, ethylene carbonate is concentrated at the points of inter section of the fibers in the nap to form a durable bond between and among themselves as depicted in the drawing.
  • a conventional drying apparatus such as a chain dryer or an oven
  • the period of time the fabrics were heated ranged from 2 minutes to 15 minutes, with the preferred being 4 to 5 minutes, at a temperature of from 250 F. to 350 F. with the preferred temperature being 280 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 composition was added onto the nap by conventional spraying or fogging methods well known in the textile field. Other agents such as water repellents and anti-static agents may be added to the original stabilizing composition solution which would have resulted in giving the mapped fabrics not only stability to laundering, wearing, and a soft hand, but a permanent anti-static and water repellent property.
  • the dyed fabrics were then washed and their shedding, pilling and matting properties were observed along with the hand. There was no excessive shedding, pilling and matting and the hand remained soft.
  • the polymeric materials which may be employed in the practice of the present invention, are polyacrylonitrile, copolymers, including binary and ternary polymers containing at least percent by weight of acrylonitrile in the polymer molecule, or a blend comprising polyacrylonitrile or copolymers comprising acrylonitrile with from 2 to 50 percent of another polymeric material, the blend having an overall polymerized acrylonitrile content of at least 80 percent by weight.
  • the preferred polymers employed in the instant invention are those containing at least 80 percent of acrylonitrile, generally recognized as the fiber-forming acryloni-trile polymers, it will be understood that the invention'is likewise applicable to polymers containing less than 80 percent acrylonitrile.
  • the acrylonitrile polymers containing less than 80 percent acrylonitrile are useful in forming films, coating compositions, molding operations, lacquers, etc.
  • Suitable monoolefinic monomers include acrylic, alpha-chloroacrylic and methacrylic acids; the acrylates, such as methylmethacrylate, ethylmethacrylate, butylmethacrylate, methoxymethyl methacrylate, beta-chloroethyl methacrylate, and
  • betadicarboxylic acids or their anhydrides or derivatives are betadicarboxylic acids or their anhydrides or derivatives,
  • the polymer may be a ternary or'higher .interpolymer, for example, products obtained by the interpolymerization of acrylonitrile and two or more of any of the monomers, other than acrylonitrile, enumerated above. More specifically, and preferably, the ternary polymer comprises acrylonitrile, methacrylonitrile, and 2-vinylpyridine.
  • ternary polymers preferably contain from 80 to 98 per- 'cent by acrylonitrile, from 1 tov 10 percent of a vinyl- ..pyridine or a l-vinylimidazole, and from 1 to 18 percent of another substance such 'as methacrylonitr'ile or vinyl chloride.
  • the polymer may'also be a blend of a polyacrylonitrile 'or. of a binary interpolymer of from 80 to 99 percent acrylonitrileand from 1 to.20 percent of at least one other.
  • the polymeric material when it comprises a blend, it will be a blend of a copolymer of 90 to 98 percent acrylonit'rile and from 2 to 10 percent of another monomer-olefinic monomer, such as vinyl acetate, which is not receptive to dyestuff, with a suflicientamount of a copolymer of from 10 to 70 percent of acrylonitrile and from 30 to 90 percent of a vinyl-substituted tertiary 'heterocyclic.
