Patent ID: 7833447

Claim:
A process for producing a textile hygiene article selected from the group consisting of diapers, sanitary napkins, inserts, slip inserts, and incontinence guards from thin crimped tows of melt-spun LOY, POY or FOY polyester filaments having an individual titer of 1 to 16 dtex, produced by a process which comprises the steps of: a) separately winding individual LOY, POY or FOY polyester filament yarns onto creeled bobbins, b) withdrawing the individual filament yarns from the creeled bobbins, the number of bobbins and the linear density of the individual filaments and yarns corresponding to the total linear density of the thin crimped tow, c) converging the individual filament yarns together to form a homogeneous filament yarn tow, d) providing the filament yarn tow with a processing finish, e) withdrawing the finished filament yarn tow by means of a drawing apparatus which comprises two pairs of draw rolls and which effects drawing, afterdrawing, and/or tension uniformization through low tension draft and preheating, f) subsequently heating the filament yarn tow by means of a heating apparatus, and g) stufferbox crimping the set filament yarn tow, wherein the total linear density of the stufferbox crimped tow is in the range from 2 ktex to 9 ktex and the stufferbox crimping operation is effected at a speed in the range of 200 m/min to 1000 m/min, h) and further processing the tows into said hygiene article.
