摘要:
A method for producing a fire resistant thread comprising the steps of: unwinding a first yarn being a fire resistant polymer from a first spool onto a first pirn; unwinding a second yarn being a synthetic and/or natural yarn from a second spool onto a second pirn; unwinding a third yarn being a synthetic and/or natural yarn from a third spool onto a third pirn; unwinding the first yarn, the second yarn and the third yarn from the first pirn, the second pirn and the third pirn; twisting the first yarn, the second yarn and the third yarn each in a first direction; twisting the first yarn, the second yarn and the third yarn together in a second direction to form a three-ply thread; coating the three-ply thread with a bonding agent in order to form the fire resistant thread; and collecting the fire resistant thread.
