ABSTRACT:
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.
