Abstract

The invention discloses a multifunctional flame retardant blanket and a preparation method thereof. The multifunctional flame retardant blanket uses the following fiber materials (in weight ratio): 20% to 50% of SOL FR fiber, 20% to 50% of polyimide fiber %, 20% to 40% of flame-retardant acrylic fiber, and 1% to 3% of conductive fiber are blended. The flame-retardant blanket produced by the invention has multiple functions such as comfort, permanent flame-retardant, anti-bacterial, anti-mite, and far-infrared.

Description

technical field [0001] The invention belongs to the technical field of textile science, and relates to a multifunctional flame-retardant blanket and a preparation method thereof. Background technique [0002] At present, there are aramid flame-retardant blankets, acrylic flame-retardant blankets, polyester flame-retardant blankets, etc. in the flame-retardant blanket market. Sex is single, and function and comfort cannot be taken into account. Aramid flame-retardant blankets have poor moisture absorption and air permeability, hard texture, and poor comfort; although acrylic flame-retardant blankets are soft in texture, they are prone to static electricity and generate a lot of smoke in case of fire; polyester flame-retardant blankets have poor moisture absorption and air permeability and are prone to static electricity. , there is also the defect that molten dripping can easily cause secondary damage. Contents of the invention [0003] The technical problem solved by the...
