Abstract

The invention discloses a multifunctional flame-retardant blanket and a preparation method thereof. The multifunctional flame-retardant blanket is prepared by blending the following fiber materials inpercentage by weight: 20-50% of SOL FR fibers, 20-50% of polyimide fibers, 20-40% of flame-retardant acrylic and 1-3% of conductive fibers. The flame-retardant blanket produced in the invention has multiple functions of being comfortable, permanently flame retardant, antibacterial, anti-mite, far-infrared and the like.

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...
