A process is described for producing thin crimped tows from LOY, POY, or FOY filaments in a total linear density from 2 ktex to 9 ktex by filament yarns being withdrawn from creeled bobbins, folded and provided with a processing finish, then drawn or tension-uniformized and thereafter heated and stufferbox crimped. The process can be carried out in-line with numerous further processing operations. The tows are particularly useful for producing textile hygiene articles such as diapers, sanitary napkins, inserts and incontinence guards and the like.

The invention relates to a bioactive fiber product that, as a bioactively effective constituent, contains only one polyester fiber, which is largely or exclusively made of a polyester having links, which are condensed therewith and which contain phosphorous. The bioactive fiber products are suited for all textile products for which antibacterial, fungicidal, acaricidal and similar effects are sought.

The invention relates to a method and to a device for detecting a thickening in a running thread. The thread runs through a forked guide element which is moved away from an initial position by a thickening in the thread, thereby triggering a signal. While the guide element is moved away, it allows the thread having the thickening to continue running and is then returned to its initial position.
