Abstract: Artificial filaments or threads have applied thereto a wax-like substance emulsifiable in aqueous media.  The treated threads yield better results in winding, weaving, knitting and like operations. The process may be applied to cellulose ester or ether filaments or threads.  The wax-like substance may be an ester of a higher fatty acid with a polyhydric alcohol such as a stearate or oleate of tri- or diethylene glycol, ethylene glycol, triethanolamine, or mono- or di-ethanolamine, or a di-stearate or oleate of glycerol.  Esters of palmitic or other higher fatty acid with glycol, polyglycols, glycerols, or higher polyhydric alcohols may be used.  The threads may be provided with a coating containing also a harder waxy substance such as ceresin wax, beeswax, stearic acid, stearin, palmitic acid, ozokerite wax, carnauba wax, and chlorinated naphthalene.  The coating solution may contain also a softening or plasticizing agent such as olive oil, oleic acid, glycols, diethylene glycol, glycerols, or their esters or ethers.  Carriers such as cottonseed oil, tung oil, and rape-seed oil, or wetting and dispersing agents such as triethanolamine, ethylene diamine, and sulphonated naphthalene may be present.  Solvents such as naphtha, xylene, olive oil, triethanolamine esters or ethers, glycols, glycerols, mineral oil, glycol ethers, glycol esters, cyclohexanol, ethyl oxybutyrate, butyl alcohol, butyl acetate, and ethylene diamine may be used. Other substances which may be added are cresylic acid, butyl acetate, polymerized fatty acid, glycero-and glyco-boric acid, cetyl alcohol, and higher fatty alcohol esters or ethers.  The filaments or threads may be continuous or discontinuous. Bristles, straws, or ribbons, may be treated.  The threads may contain pigments, dyes, lakes, fillers, and fire retardants such as b -chlornaphthalene or tri-phenyl phosphate.  The coating may be applied at any stage of thread production or conversion, by means of wicks, rollers, or discs.  It may be applied continuously with dry spinning.  Hanks may be dipped in the coating solution, or the solution may be forced through the windings of bobbin, cheese or other package.  The solution may be sprayed.  The wax-like substance is applied in solution, or aqueous emulsion, or while in molten condition.  The coating may be applied to cellulose ester or ether staple fibre before or after cutting or before or after spinning into threads.  Fugitive colours permitting identification of the threads in textile processing may be added to the coating solution.  Acid Green G, Violet 5BK, or Xylene Blue may be used with triethanolamine stearate or oleate.  The yarns may subsequently be scoured.ALSO:Artificial filaments or threads have applied thereto a wax-like substance emulsifiable in aqueous media.
