Patent

CA 2500958

A ply-twisted yarn useful in cut resistant fabrics is made by providing a first multifilament yarn of continuous organic filaments having a tensile strength of at least 4 grams per denier and having a twist in a first direction of from 0.5 to 10 turns per inch; providing a second yarn comprising 1 to 5 continuous inorganic filament(s); and ply-twisting the first yarn and the second yarn about each other 2 to 15 turns per inch in a second direction opposite to that of the twist in the first yarn to form a ply-twisted yarn having an overall effective twist of +/- 5 turns per inch.

L'invention concerne un fil retordu employé dans des toiles résistant aux coupures, fabriqué par mise en oeuvre d'un premier fil multifilament, formé de filaments organiques continus, présentant une contrainte de rupture d'au moins 4 grammes par denier, et une torsion, dans un premier sens, de l'ordre de 0,5 à 10 tours par pouce ; mise en oeuvre d'un deuxième fil contenant 1 à 5 filaments inorganiques continus ; et, retordage du premier fil et du deuxième fil l'un autour de l'autre, de l'ordre de 2 à 15 tours par pouce, dans un deuxième sens opposé à celui de la torsion du premier fil, de manière à former un fil retordu présentant une torsion réelle globale de +/- 5 tours par pouce.
