Embodiment Construction
[0022] A functional flame-retardant fiber, including cellulose, is characterized in that: it also includes nano-scale additive powder of tourmaline and silicon dioxide; its components are by weight percentage:
[0023] Cellulose: 75% to 95%;
[0024] Nanoscale additive powder of tourmaline and silicon dioxide: 5% to 25%;
[0025] Wherein: the nano tourmaline powder accounts for 40%-70% of the total weight of the nano-scale additive powder, and the silicon dioxide accounts for 30%-60% of the total weight of the nano-scale additive powder. The volume percentage of the nano-scale additive powder with nano particles below 100nm accounts for more than 70% of the total volume.
[0026] The production method of a kind of functional flame-retardant fiber of the present invention, specifically has the following steps according to the production process sequence:
[0027] (1) Select tourmaline and silicon dioxide and grind them step by step. Using the principle of centrifugal force f...
