Definitions

• the invention relates to the use of triacetin in textile lubricants and a method for reducing the viscosity of textile lubricants.
• Melting should ensure optimal yarn production from loose or upstream fiber materials and must therefore in particular improve the adhesive and sliding properties of synthetic staple fibers, natural fibers and / or mixtures of natural and synthetic fiber materials (Chwala / Anger: "Handbuch der Textilhilhilstoff", chapter 3.7, publisher Chemistry, Weinheim 1977).
• Fiber preparations and lubricants which contain smoothing agents, antistatic agents and / or emulsifiers as their main active substances, are solid, pasty or viscous. Since preference is given to liquid fiber preparations and slicing for processing reasons, fiber preparations and slicing are converted into a liquid form using adjusting agents (diluents). However, the higher the leveling agent content required for the desired viscosity, the more the effectiveness, in particular the effectiveness of the lubricant, of the preparations and lubricants decreases. Glycols and / or alkyl glycols are usually used as adjusting agents, but their toxicology is not harmless.
• the object on which the invention is based was therefore the development of fiber preparations and lubricants which have a viscosity suitable for the application, which prevent the tendency of fiber preparations and lubricants to curl, but at least considerably reduce them, and give the fiber materials excellent smoothness properties and very good antistatic properties. Furthermore the fiber preparations and lubricants to be developed are subject to the condition of being physiologically harmless.
• the invention accordingly relates to the use of triacetin in textile lubricants based on smoothing agents, antistatic agents and / or emulsifiers.
• 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.
• textile lubricant includes in particular fiber preparations and finishing agents, for example smelting ("Ullmanns 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-A-33 929, by reacting glycerol with acetic acid and acetic anhydride, if appropriate in the presence of catalysts.
• the textile lubricants 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 palmitate, isobutyl stearate and / or 2-ethylhexyl tallow fatty acid, 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 (chemical 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 palmitate, isobutyl stearate and / or 2-ethyl
• Suitable emulsifiers, wetting agents and / or antistatic agents are anionic, cationic and / or nonionic surfactants, such as mono- and / or diglycerides, for example glycerol mono- and / or glycerol dioleate, alkoxylated, preferably ethoxylated and / or propoxylated fats, oils, fatty alcohols 8 to 24 carbon atoms and / or C8 ⁇ 18 alkylphenols, for example castor oil with 25 moles of ethylene oxide (EO) and / or C16 ⁇ 18 fatty alcohol with 8 moles of propylene oxide and 6 moles of EO, if desired alkoxylated C8 ⁇ 24 fatty acid mono- and / or -diethanolamides, for example optionally ethoxylated oleic acid mono- and / or -diethanolamide, tallow fatty acid mono- and / or -diethanolamide and / or coconut fatty acid mono-
• 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 simultaneously act as an antistatic agent and / or as an emulsifier.
• the optional triacetin-containing textile lubricants 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-A-38 30 468, pH regulators, for example C1 ⁇ 4-carboxylic acids and / or C1 ⁇ 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-A-38 30 468
• pH regulators for example C1 ⁇
• Triacetin-containing melts are usually sprayed onto synthetic staple fibers, natural fibers or mixtures of natural and synthetic fiber materials.
• the quantity of 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 quantity 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.
• Triacetin which is toxicologically and ecologically harmless, also significantly reduces 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 mm2 / s at 20 ° C., and the viscosity of a 20% by weight aqueous emulsion was 31 mm2 / s at 20 ° C.
• the viscosity of the preparation was 115 mm2 / s at 20 ° C, the viscosity of a 20% by weight aqueous emulsion at 20 ° C was 23 mm2 / s.
• the viscosity of the preparation was 90 mm2 / s at 20 ° C, the viscosity of a 20 wt .-% aqueous emulsion at 20 ° C 7.5 mm2 / s.
• the viscosity at 20 ° C was 187 mm2 / s, the viscosity of a 20 wt .-% aqueous emulsion at 20 ° C 73 mm2 / s.
• the undiluted spin finishes A to D which had a temperature of 20 ° C., were applied to a preparation-free polypropylene multifilament (142 dtex) using a metering pump (oil coating: 0.5% by weight).
