Definitions

• the multifilament threads are wound onto the spinning bobbin without rotation.
• the individual capillaries are in the form of a parallel bundle of threads, the cohesion of the individual capillaries only being brought about by the more or less pronounced adhesive effect of the spin preparation.
• these yarns are usually given a protective twist of a few turns per meter.
• this protective twist is not sufficient for many subsequent processing processes.
• the threads must therefore either be twisted in a separate process step or else protected by covering them with a size film. Both twisting and finishing are expensive additional process steps. For this reason, alternatives have long been sought in order to improve the thread closure of the yarns in such a way that these process steps become superfluous.
• the spin finishes used hitherto contain additives such as sarcosides or higher-viscosity polymers such as polyisobutylene as thread binding agents.
• substances of this type are able to improve the thread-closing effect of spin finishes by increasing the adhesive forces between the individual capillaries.
• this only provides a temporary thread closure, because these substances the first wet process - for example when dyeing - washed out again.
• Another disadvantage that many of these thread locking agents have is their inadequate thermal stability. This severely limits their use for spin finishes intended for texturing or for technical yarns that have to undergo a hot stretching process.
• the invention relates to spin finishes for melt spinning synthetic fiber materials based on smoothing agents, emulsifiers, wetting agents, antistatic agents and, if appropriate, other additives, characterized by a content of 1-30, preferably 5-15,% by weight of a C 8 -C 24 - epoxyalkyl compound.
• the invention further relates to a method for achieving permanent thread closure during melt spinning of synthetic fiber materials, the claimed spin finish being applied to the fiber material in an amount of 0.3-2.0% by weight and then being heated to 150-250 ° degrees .
• the C 8 -C 24 epoxyalkyl compounds mentioned are derived from unsaturated C 8 -C 24 -alkyl-containing fatty acids, fatty alcohols, fatty acid esters or olefins.
• One or more epoxy groups are introduced by known methods, for example by reacting the compounds containing at least one carbon double bond in the alkyl radicals with hydrogen peroxide in the presence of formic acid.
• Preferred products are the epoxidation products of unsaturated C 12 -C 18 fatty acids, fatty alcohols and fatty acid esters, for example methyl fatty acids or fatty acid glycerides, and C 12 -C 18 olefins examples suitable products are the epoxidation products of oleic acid methyl ester, soybean oil fatty acid methyl ester, soybean oil, mixtures of unsaturated C 12 -C 18 fatty alcohols, 1,2-hexadecene, and the like.
• Common smoothing agents are mineral oils, fatty acid esters and alkylene oxide adducts or polymers.
• Suitable emulsifiers, wetting agents and antistatic agents are anionic and nonionic surfactants, such as ethylene oxide adducts with higher fatty alcohols, alkylphenols or other fatty substances, triethanolamine soaps, alkanesulfonates, phosphoric acid esters and the like into consideration.
• the treated threads are subjected to heat treatment, using temperatures of 150-250 ° C., preferably 150-230 ° C.
• This thermal aftertreatment which is a prerequisite for the occurrence of the thread closure effect, can be carried out immediately after application of the preparation or at a later point in time in a separate operation. At normal room or storage temperature, the preparations are sufficiently stable over long periods.
• the method is suitable for achieving a permanent, temperature- and wash-resistant thread closure effect in the production of textile yarns, technical yarns or BCF (bulked continuous filament) yarns made of polyamide (PA), polyester (PES) or polyolefin, e.g. B. Polypropylene (PP) - Changes in the usual procedure are - apart from the thermal treatment - not required.
• the spin finishes given below were applied as 10-25% aqueous emulsions to various fiber materials immediately after the melt spinning process.
• the application was carried out by means of application rollers in an amount of 0.5-1.3% by weight, based on the anhydrous preparation. Following the order, thermal fixation was carried out by heating to 150-230 ° C.
• the preparation of Example 7 contained no epoxy compound and served as a comparison substance.
• the thread closure effect was tested in the following way: The thread to be tested is clamped vertically in a holding device. The total length of the thread is 50 cm. The lower end of the thread is loaded with a weight of 5.7 g / tex. The thread is cut at 40 cm thread length with sharp scissors.
