Definitions
- Another object of the invention is a method for reducing the viscosity of textile lubricants, which is characterized in that textile lubricants based on smoothing agents, antistatic agents and / or emulsifiers are mixed with triacetin.
- triacetin as an adjusting agent in textile lubricants is also an object of the invention.
- textile lubricant includes, in particular, fiber preparations and finishing agents, for example smelting ("Ull ann's Encyclopedia of Industrial Chemistry", volume 23, pages 5-6, Verlag Chemie Weinheim 1983).
- the triacetin to be used according to the invention can be prepared in a manner known per se, for example according to EP 33 929, by reacting glycerol with acetic acid and acetic anhydride, if appropriate in the presence of catalysts.
- Smoothing agents are used to produce the textile lubricants according to the invention, in particular fiber preparations and lubricants iffld / or antistatic agents and / or emulsifiers and / or optionally further additives and / or optionally water mixed with triacetin at 18 to 25 ° C. Textile lubricants are preferred
- wetting agent 1 to 40% by weight triacetin 0 to 10% by weight additives e.g. B. pH regulators, thread closure agents,
- the textile lubricants according to the invention can be used as smoothing agents, for example mineral oils, fatty acid esters with 8 to 22 carbon atoms in the fat residue and 1 to 22 carbon atoms in the alcohol residue, for example methyl palmititic acid, isobutyl stearate and / or tallow fatty acid 2-ethylhexyl ester, Polyol carboxylic acid esters, for example coconut fatty acid esters of glycerol and / or alkoxylated glycerols, silicones, for example dimethylpolysiloxane and / or polyalkylene glycols, for example ethylene oxide / propylene / oxide mixed polymers with average molecular weights between 600 and 6,000 (cheese fibers / textile industry 1977 335) included.
- mineral oils for example mineral oils, fatty acid esters with 8 to 22 carbon atoms in the fat residue and 1 to 22 carbon atoms in the alcohol residue, for example methyl palmititic acid, is
- Suitable emulsifiers, wetting agents and / or antistatic agents are anionic, cationic and / or nonionic surfactants, such as mono- and / or diglycerides, for example glycerol ono- and / or glycerol dioleate, alkoxylated, preferably ethoxylated and / or propoxylated fats, oils , Fatty alcohols with 8 to 24 carbon atoms and / or C ⁇ -is-alkylphenols, for example castor oil with 25 moles of ethylene oxide (E0) and / or Ci5_i8 fatty alcohol with 8 moles of propylene oxide and 6 moles of E0, if desired alkoxylated C8-24 fatty acid mono- and / or diethanolamides, for example optionally ethoxylated oleic acid mono- and / or diethanolamide, tallow fatty acid ono- and / or diethanolamide and / or coconut fatty acid mono- and /
- smoothing agents In this exemplary list of smoothing agents, emulsifiers, antistatic agents and / or wetting agents, it must be taken into account that a large number of the substances mentioned have not only one function but several functions: for example, a smoothing agent can also be used simultaneously as an antistatic agent and / or as Emulsifier act.
- the triacetin-containing textile lubricants according to the invention contain thread closure agents, e.g. B. polyacrylates, fatty acid sarcosides and / or copolymers with Maleic anhydride (Melliand Textile Reports 1977, 197) and / or polyurethanes according to DE 38 30 468, pH regulators, for example C 4 -carboxylic acids and / or 4-hydroxycarboxylic acids, such as acetic acid and / or glycolic acid, alkali metal hydroxides, such as potassium hydroxide and / or amines such as triethanolamine, bactericides and / or anti-corrosion agents.
- thread closure agents e.g. B. polyacrylates, fatty acid sarcosides and / or copolymers with Maleic anhydride (Melliand Textile Reports 1977, 197) and / or polyurethanes according to DE 38 30 468
- pH regulators for example C 4 -carboxylic acids and / or 4-
- Triacetin-containing melts are usually sprayed onto synthetic staple fibers, natural fibers or mixtures of natural and synthetic fiber materials.
- the quantity of the melt applied in undiluted form or in a mixture with water is between 0.1 and 3% by weight, based on the weight of the fiber materials.
- Triacetin-containing fiber preparations are applied in a known manner immediately after the capillaries have emerged from the spinneret.
- the fiber preparations which have a temperature between 18 and 60 ° C, are applied with the help of application rollers or with metering pumps using suitable applicators.
- the amount of fiber preparations applied in undiluted form or in the form of aqueous emulsions is between 0.3 and 2% by weight, based on the weight of the thread bundle. After treatment with the preparations, the bundles of threads are wound on spinning bobbins.
- the aqueous emulsions of triacetin-containing fiber preparations usually contain 5 to 30% by weight of the undiluted fiber preparation.
- the fiber preparations according to the invention are preferably applied undiluted to polymeric filament materials, for example polypropylene, polyester and / or polyamide filaments.
- polymeric filament materials for example polypropylene, polyester and / or polyamide filaments.
- triacetin as adjusting agent in textile lubricants has no negative influence on the smoothing and antistatic effectiveness of such textile lubricants.
- triacetin which is toxicologically and ecologically harmless, brings about a significant reduction in the tendency of textile lubricants to gel.
- the viscosities were determined using a Ubelhode viscometer.
- Fiber preparations of the following composition were used:
- the viscosity of the preparation was 146 mm 2 / sec at 20 ° C, the viscosity of a 20% by weight aqueous emulsion at 31 ° C / mm at 20 ° C.
- the viscosity of the preparation was 115 at 20 ° C the viscosity of a 2M wt .-% aqueous emulsion at 20 ° C 23 mm2 / sec.
- Glycerin 30% by weight triacetin The viscosity of the preparation was 90 mm / sec at 20 ° C, the viscosity of a 20% by weight aqueous emulsion at 20 ° C was 7.5 mm 2 / sec.
- the viscosity at 20 ° C was 187 mm 2 / sec
- the viscosity of a 20% by weight aqueous emulsion at 20 ° C was 73 mm 2 / sec.
