Definitions

  • the invention relates to a textile fiber drafting cot having an improved non-adhesive drafting surface for extensible, smooth-surfaced fibers of polyamide and polyester types.
  • the cot composition comprises a sulfur-cured butadiene-acrylonitrile copolymer and filler.
  • the composition also includes as the critical ingredient therein 5-35 parts by weight of toluene sulfonamide per 100 parts by weight of the butadiene-acrylonitrile copolymer. This amount of toluene sulfonamide will bring about a bloom to the surface of the cot. This bloom on the surface of the cot eliminates the adhesive properties normally found on the surface of the oil-resistant synthetic rubber cot compositions even Where a static charge is not involved.
  • the drawing shows a typical textile fiber drafting cot in which the metal arbor 1 is the core of the drafting cot 2 having the drafting surface 3 on which is a bloom of toluene sulfonamide.
  • the oil-resistant synthetic rubber to be used in cots of the present invention will be NBR rubbers, the butadieneacrylonitrile copolymers containing normally 25-40% by weight acrylonitrile in the copolymer.
  • the toluene sulfonamide is sufiiciently incompatible with thi particular rubber to bloom to the surface of the cot.
  • bloom is meant that the incompatibility of the toluene sulfonamide is sufficient that the sulfonamide diffuses to the surface of the cot at a rate slow enough to be effective over the working life of the cot and fast enough to affect the drafting surface characteristics of the cot.
  • the NB R rubbers will be blended with other ingredients standard in the cot composition art. Particularly, there will 'be reinforcing fillers in the nature of carbon black. Softeners in the nature of polyethylene glycol or polyether dibutoxyethoxyethylformate may be added, along with such customary additives as glue, and detergents and wetting agents such as polyethylene glycol monolaurate to impart anti-static properties to the drafting surface of the cot. Clays (such as kaolin), zinc oxide, pigments, retarders (such as salicylic acid), may all be used.
  • a sulfur-containing curing system willbe used to cure the rubber.
  • Such systems often include sulfur itself along with accelerators such as benzothiazyl disulfide, N-nitroso diphenylamine, 2-benzothiazole sulphenamide, and the like.
  • accelerators such as benzothiazyl disulfide, N-nitroso diphenylamine, 2-benzothiazole sulphenamide, and the like.
  • additional resins such as coumarone-indene resins are added as tackifier resins.
  • the cot composition may be a conventional NBR composition, With the toluene sulfonamide as an additional ingredient. All of the ingredients are blended into the NBR rubber in the usual manner as by milling or intensive mixing, followed by the formation of a cot by extrusion. The cots are then cured and ground to size as customary.
  • the toluene sulfonamide to be added to the composition may be in the form of the ortho or para isomer.
  • mixtures of ortho and para may be cheaper than either isomer alone, and hence may be more desirable to use.
  • the formulate for the two isomers are as follows:
  • the amount of toluene sulfonamide should be in the range of 5-35 parts by weight toluene sulfonamide per parts by Weight NBR rubber. As a practical matter, 15 parts by weight toluene sulfonamide per 100 parts by weight NBR rubber will give a good working all-around composition.
  • a composition having an improved no-adhesive drafting surface for extensible, smooth-surfaced fibers of the polyarnide and polyester type comprising a sulfur-cured butadiene-acrylonitrile copolymer and filler, and including 535 parts by weight toluene sulfonamide per parts by weight of said copolymer sufficient to bloom to the surface of the composition.
  • composition according to claim 1 containing 15 parts by weight toluene sulfonamide per 100 parts by weight of said copolymer.
  • composition according to claim 1 wherein said filler comprises carbon black.
