    Abstract: Diethylaminoethyl (DEAE)-Cotton, prepared so that the tertiary amine nitrogens have unshared electrons and are thus in the Lewis-base form, is reacted with an alcoholic solution of an alpha-omega dihaloalkane to quaternize amino groups. The fabric produced by this process is crosslinked between tertiary amine nitrogen groups in cellulose and every alkylene group introduced is connected to two quaternary ammonium ions. The products of this process have strong base anion exchange properties and fabrics of high nitrogen content are imparted both wet and dry crease resistance.

  • Patent number: 4014800
    Abstract: Amine oxides of the formula R.sup.1 R.sup.2 R.sup.3 N.fwdarw.O, in which R.sup.1 is medium- to long-chain alkyl, R.sup.2 is short- to long-chain alkyl or polyethyleneglycol, R.sup.3 is short chain alkyl or polyethyleneglycol, with the provisos that the polyethylene glycol groups together have not more than 10 glycol units, and that R.sup.3 is polyglycol if R.sup.2 is medium- to long-chain alkyl, are useful as antistatic agents in lubricating agents for synthetic fibers. The amine oxides are distinguished by a good thermal stability, are low-volatile, non-corrosive, compatible with usual lubricating agents and soluble in aqueous and oily lubricating compositions.
