POLYMER FOAMED FIBER, AND PREPARATION METHOD AND USE THEREOF

Abstract: provided are a polymer foamed fiber and a preparation method thereof. the polymer foamed fiber has a closed-pore structure in an interior, the closed-pore structure comprises uniform and dense pores and an average pore size of the pores in the closed-pore structure is in a range of from 1 �m to 50 �m. the polymer foamed fiber has a diameter in a range of from 0.08 mm to 1.0 mm with an average deviation of the diameter of �0.05 mm, a skin layer thickness in a range of from 0 to 0.1 mm, a density in a range of from 0.30 g/cmto 0.90 g/cm, and an elongation at break in a range of from 0 to 600%. the polymer foamed fiber has advantages, such as, light weight, uniform fiber thickness, a porous structure, dense internal pores with uniform pore sizes and a controllable skin layer thickness.
