An article is provided that comprises fibers, as is a method of forming the article. The fibers comprise an organopolysiloxane component selected from (i) an organopolysiloxane having the formula (R3SiOi/2)w(R2Siθ2/2)x(RSiθ3/2)y(Siθ4/2)z (I), wherein each R is selected from the group of an inorganic group, an organic group, and combinations thereof, w is from 0 to 0.95, x is from 0 to 0.95, y is from 0 to 1, z is from 0 to 0.9, and w+x+y+z=1, and (ii) a cured product of said organopolysiloxane having the formula (I), and combinations of (i) and (ii), provided that the fibers are free from organic polymers, organic copolymers, and organosiloxane-organic copolymers. The method of forming the article includes the step of forming fibers from a composition. The composition used to form the fibers comprises the organopolysiloxane having the formula (I), provided that the composition is free from organic polymers, all-organic copolymers, and organosiloxane-organic copolymers. The article exhibits excellent hydrophobicity and maximized fire resistance.
An article comprising fibers having an average diameter of from about 0.01 μm to about 100 μm, said fibers comprising an organopolysiloxane component selected from (i) an organopolysiloxane having the formula (R3SiO1/2)w(R2SiO2/2)x(RSiO3/2)y(SiO4/2)z (I), wherein each R is selected from the group of an inorganic group, an organic group, and combinations thereof, w is from 0 to about 0.95, x is from 0 to about 0.95, y is from 0 to 1, z is from 0 to about 0.9, w+x+y+z=1, and y+z is from about 0.1 to 1, (ii) an organopolysiloxane having the formula (I), wherein each R is selected from the group of an inorganic group, an organic group, and combinations thereof, w and x are each independently greater than 0, w+x+y+z=1, and y+z is less than about 0.1, (iii) a cured product of said organopolysiloxanes (i) and/or (ii), and combinations of (i), (ii), and (iii), provided that said fibers are free from organic polymers, all-organic copolymers, and organosiloxane-organic copolymers.
