1. fine fibre that comprises polymer, described polymer is selected from:

  • (a) blend of hydrophobic additive and nylon 66, the fiber size of described fine fibre is about 0.001-0.5 micron;

    (b) blend of hydrophobic additive and following polymer, described polymer comprises the mixture of at least two kinds of different nylon polymers, the fiber size of described fine fibre is about the 0.01-0.5 micron;

    (c) blend of hydrophobic additive and nylon polymer, described nylon polymer comprise the nylon except the copolymer that is formed by cyclic lactam and C6-10 diamine monomer or C6-10 diacid monomer, and the fiber size of described fine fibre is about the 0.01-0.5 micron;

    (d) product of crosslinking agent and nylon polymer;

    Or(e) mixture of said components;

    After wherein exposing 1-16 hour in the air of 140  and

    100% relative humidity, it is constant substantially that at least 30% fine fibre keeps.
