FIRE-RESISTANT KNITTED MATERIAL Russian patent published in 2021 - IPC D04B1/16 

FIELD: fire-resistant knitted material.

SUBSTANCE: fire-resistant knitted material has a thickness of 0.08 mm or more according to the JIS L 1096-A (2010) method and consists of yarn. Yarn contains: a non-melting fiber A having a high temperature shrinkage of 3% or less; and a thermoplastic fiber B having an LOI of 25 or more according to JIS K 7201-2 (2007) and having a melting point lower than that of the non-consumable fiber A. Yarn has breaking elongation exceeding 5%. The area fraction occupied by the non-consumable fiber A in the projected area of ​​the knitting repeat of the fire-resistant knitted fabric is 10% or more, and the area fraction occupied by the thermoplastic fiber B is 5% or more.

EFFECT: disclosed is fire-resistant knitting material characterized by high fire resistance.
