  • Abrasion resistant reinforced fabric
    Patent number: 5321960
    Abstract: A reinforcing yarn and an abrasion resistant knitted fabric made therewith are disclosed. The reinforcing yarn is made by Z twisting one end of a "Z"-twist textured yarn together with one end of a "S"-twist textured yarn to yield an S/Z yarn pair, which is then reverse twisted together with a duplicate S/Z yarn pair to yield a 4-end multi-twisted reinforcing yarn. This reinforcing yarn is knit in plaited relationship to the body yarn of a fabric to produce a fabric with exceptional abrasion resistance.

  • Abrasion resistant reinforced fabric
    Patent number: 5319950
    Abstract: A reinforcing yarn and an abrasion resistant knitted fabric made therewith are disclosed. The reinforcing yarn is made by pairing one end of a "Z"-twist textured yarn together with one end of an "S"-twist textured yarn to yield an S/Z yarn pair. The S/Z yarn pair is then axially twisted in a first direction and stretched before being helically wrapped in the opposite direction with a duplicate S/Z yarn pair to yield a 4-end composite reinforcing yarn. This reinforcing yarn is knit in plaited relationship to the body yarn of a fabric to produce a fabric with exceptional abrasion resistance.
