A flame retardant fabric is directly woven from flame retardant viscose fiber added with inorganic silicon for covering the outside of flammable articles, wherein the flame retardant viscose fiber having denier, strength and flame retardant effect which use silicic acid as the flame retardant, and coating a layer of organic material, melamine flame retardant resin on the surface of silicic acid, and then preparing the flame retardant viscose fiber into an nano-sized particles. The flame retardant fabric has a fineness of 1.11 to 2.78 dtex, and a strength of ≥2.0 cN/dtex, which meets the production requirements of spinning, and does not need to be blended with other high-strength fibers when spinning, and the woven fabric from the flame retardant viscose fiber does not need to be flame retardant, so that the flame retardant fabric has a good flame retardant effect and saves costs through simply the production process.

The present invention relates to a filament for 3D printing, comprising (A) at least one semicrystalline polyamide, (B) at least one amorphous polyamide (C) at least one flame retardant of formula (I), wherein R.sup.1 and R.sup.2 are independently of each other a linear or branched C.sub.1-C.sub.8alkyl group, or an optionally substituted aryl group, M represents is an alkali metal ion, an alkaline earth metal ion, an aluminum ion, a zinc ion, an iron ion or a boron ion; m represents 1, 2 or 3; and n represents 1, 2 or 3, a process for the preparation of the filament and its use in a process for preparation of a three-dimensional object, by a fused filament fabrication process.

The present disclosure discloses a phase-change flame-retardant fiber material for thermal management of a lithium ion battery in a closed space and a preparation method. The phase-change flame-retardant fiber material is prepared in a coaxial electrostatic spinning manner and includes a composite phase-change fiber material PASA-TPU at a core part and a flame-retardant fiber material TB-PAN wrapping a surface of the core part. The composite phase-change fiber material is well wrapped with the flame-retardant fiber material, and the lithium ion battery wrapping the whole phase-change flame-retardant fiber material in the closed space is subjected to charge-discharge cycle; the result shows that the surface temperature of the battery can be effectively reduced by about 20° C. by the material, and the material can effectively play a role in multiple cycle processes; the whole material has an excellent and stable heat absorption effect, and has no leakage and collapse; and the phase-change flame-retardant fiber material only has thermal shrinkage and blackening phenomena and is not combusted after being ignited by open fire for over 20 s. Therefore, the phase-change flame-retardant fiber material of the present disclosure has a relatively good flame-retardant effect compared with other phase-change materials.
