Definitions

• the known lubricating compositions comprise emulsions of a polymer or a mineral oil in Water, with suitable additives. These lubricating compositions although satisfactory for the subsequent textile operations at room temperature, give rise to a cumulative solid deposit when the filaments and yarns make sliding contact with hot metal surfaces, during prolonged running. Frequent cleaning of the hot metal surfaces becomes necessary, to prevent sticking and breakage of the moving filaments. Moreover wear of the hot metal surfaces takes place particularly during treatment of high tenacity filaments, such as polyethylene terephthalate filaments. Furthermore considerable care is necessary in compounding these lubricating compositions in order to obtain a relatively stable emulsion and to prevent separation during stoppages and during storage, when no agitation of the emulsion takes place.
• I in a process for treating filaments and yarns by heating in sliding contact with a hot metal surface in the presence of a lubricating composition, I provide the improvement which comprises using as lubricating composition an aqueous solution containing up to 20% by weight of a polyethylene oxide condensate and up to by weight of an antistatic agent.
• the solution Preferably the solution also contains up to 1% by weight of a boundary lubricant.
• the improvement of the treatment of my invention becomes most apparent when the filaments or yarn are making sliding contact with a metal surface heated above 140 C. particularly at low transverse pressures, e.g. when the filaments make tangential contact with a substantially flat metal surface such as a hot plate. There is no formation of solid deposits from my lubricating compositions under these conditions, which bring about a considerable amount of deposition from the lubricants'of the prior art.
• high transverse pressures e.g. when the filaments or yarn are drawn round a hot pin, which in the case of polyethylene terephthalate filaments is heated to above 80 C., wear of the metal is greatly reduced using the composition of my invention as opposed to those of the prior art.
• the preferred polyethylene oxide condensates are the polyethylene glycols which are liquids at room temperature. From the polyethylene glycols those having an average molecular weight in the range 200-600 are particularly suitable. Solid polyethylene glycols of average molecular weight higher than '600 may be used if desired, but they must be soluble in the lubricating composition.
• the antistatic agents used in quantities of less than 10% by weight, must also be water soluble, and sufficiently volatile at the processing temperatures to prevent the formation of deposits during prolonged Any known agents may be used e.g. Lubrol W (registered trademark).
• boundary lubricant should be soluble in the lubricating composition. When an antistatic agent is used this may be selected to assist the dissolving of the boundary lubricant. I have found the presence of Lubrol W (registered trademark) to assist the dissolving of sodium stearate.
• Lubrol W registered trademark
• the slight tendency of some boundary lubricants e.g. fatty acid compounds, such as sodium steal-ate, to precipitate may be overcome by the inclusion of an alkali, such as sodium hydroxide, to raise the pH of the solution to between 8 and 9.
• the lubricating compositions may be applied to the filaments at any stage of manufacture prior to making contact with the hot metal surface. Conveniently this may be done, e.g. in a melt spinning process after the filaments have solidified, as the filaments come from the spinneret.
• the amount of any particular lubricating composition picked up by the filaments using a given means for application will depend on their denier and the yarn structure. Suitable amounts are 5% to 20%.
• the lubricating composition may be applied by any means known in the art in such quantities that all the filaments are covered by the lubricating composition. When the major proportion of the water evaporates from the lubricating com.- position, the remaining components form an evenly distributed film on the filametn surface.
• a second composition is prepared consisting of:
• Another lubricating composition is prepared consisting of:
• Another lubricating composition is prepared from:
• Lubricant E A lubricating composition similar to Example D is prepared using: Parts Polyethylene glycol 400 5 Antistatic agent Lubrol W 0.5 Sodium stearate-boundary lubricant 0.025 Water to make up 100 parts.
• Lubricant F A similar lubricating composition to Example E is prepared using:
• the lubricating compositions A to F are each applied to a separate large batch of solidified polyethylene terephthalate filaments as they come from the spinneret before being wound up as filament yarn, and prior to a drawing process.
• the amount of the non-aqueous components of the lubricating composition retained on the filaments is from 0.5% to 1% by wei'gth of the yarn.
• the batches of polyethylene terephthalate filament yarns are subjected to a drawing process, at speeds of at least 150 metres per minute during 14 days continuous drawing. Satisfactory drawing conditions at draw ratios up to 4.5 times are obtained using a hot pin at 85 C., followed by a hot plate at 175 C. Excellent filament yarns during 14 days continuous drawing are obtained and no build up of deposits and little wear on any of the hot chromium plated pins and plates is observed.
• polyethylene terephthalate filaments are drawn under the same conditions as described but in the presence of an aqueous lubricating emulsion comprising a mineral oil, a Turkey red oil, triethanolamine and diethylene glycol, a brown cumulative'solid deposit is formed on the plates within 12 hours drawing, and the plates require cleaning after 48 hours drawing. If the deposits are not removed frequent filament breaks occur and the uniformity of the drawn filaments is impaired.
• an aqueous lubricating emulsion comprising a mineral oil, a Turkey red oil, triethanolamine and diethylene glycol
• EXAMPLE 2 A lubricating composition as described in Example 1 is used in a process for making potentially crimped continuous polyethylene terephthalate filaments by heating the moving continuous filaments while passing over a narrow heated metal surface so that the filaments are heated non-uniformly on one side only continuously along their length while under a tension to give a stretch to the filaments of not more than 10%, as described in the above-mentioned copending application Serial No. 625,291.
• the hot metal surface is heated to a temperature above 270 up to 900 C. Prolonged continuous running is obtained using the above lubricating composition and no build up on the hot metal surface occurs.
• Running speeds of at least 500 metres per minute are possible, when using the above lubricant, in quantities such that at least 0.3% of non-aqueous components of the lubricating composition is deposited on the filaments.
• the potentially crimped filaments are wound up and subjected to a heat relaxation treatment which develops the crimp.
• Example 1 By comparison if instead of the lubricating composition of Example 1 one of the known lubricating compositions is used, comprising an aqueous emulsion of a mineral oil, Turkey red oil, triethanolamine oleate and diethylene gly- C01 in water, a deposit is formed on the hot metal surface within 3 hours, which has to be removed. Operation has to be stopped and the hot metal surface allowed to cool before the deposit is removed. In spite of this cleaning, the number of filament breaks which cause laps, is increased 30 times and the number of complete breaks in the threadline, affecting all filaments simultaneously, is increased 20 times.
• a process for thermally treating and lubricating polyethylene terephthalate filaments and yarns when making sliding contact with stationary metal surfaces heated to above C. which comprises applying to said filaments an aqueous lubricating composition which is a solution and which consists essentially of 220% by weight of a polyethylene glycol having an average molecular weight between 200 and 600 and which by itself is a liquid at room temperature, and up to 10% by weight of an antistatic agent, so that the amount of the non-aqueous component of said solution on the filaments is at least 0.2% by weight of the filaments, and thereafter slidably contacting the filaments with said metal surface at a temperature above 140 C.
• an aqueous lubricating composition which is a solution and which consists essentially of 220% by weight of a polyethylene glycol having an average molecular weight between 200 and 600 and which by itself is a liquid at room temperature, and up to 10% by weight of an antistatic agent, so that the amount of the non-aqueous component of said solution on the filaments
