Definitions

• the invention relates to the use of alkyl betaine sulfosuccinates in filament and spinning preparations as highly adhesive, antistatic, finishing and thread-closing components with extremely positive effects on the running properties of the treated material, particularly suitable for synthetic threads such as polyamide and polyester produced by the melt spinning process.
• preparations The role of these preparations is to optimize the running properties of the treated material, the fiber / fiber (F / F) and fiber / metal (F / M) friction being practically determined by the properties of the preparation film.
• various wetting and adhesive components are added to the preparations. Preparations generally consist of several components. The most important, according to their function, are: lubricants, emulsifiers, thread closure agents and antistatic agents.
• the most important properties that a modern preparation has to meet include the following: heat resistance, low volatility, good antistatic activity, good wetting ability, medium to low thread / friction body friction, sufficient thread engagement, compatibility with other aids, good washability.
• ester oil-based preparations which better meet the high temperature requirements caused by technical developments (DD 280 532 A1).
• DD 280 532 A1 the trimethylolpropane esters described
• the lack of a thermal degradation reaction leads to sticking and cracking on heating units.
• an increased proportion of thread-locking agents must be incorporated into these preparations, since the viscosity of the synthetic esters is lower than that of the mineral oils replaced.
• DD 260 405 A3 describes the use of alkyl betaines in combination with fatty acid ethoxylates and quaternized fatty acid amide compounds in order to solve the problem described and at the same time to ensure good thread closure.
