  • Production of fine stufferbox-crimped tows from synthetic filaments and further processing thereof into textile hygiene articles
    Patent number: 8277709
    Abstract: 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crimped tows from LOY, POY, or FOY filaments in a total linear density from 2 ktex to 9 ktex by filament yarns being withdrawn from creeled bobbins, folded and provided with a processing finish, then drawn or tension-uniformized and thereafter heated and stufferbox crimped.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.

  • Bioactive fiber products
    Patent number: 7858111
    Abstract: 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.
