Abstract
Disclosed herein is a fiber formed from a resin including a silicone-modified polyurethane resin comprising the reaction products of a polyol (A), a chain extender (B), an active-hydrogen-group-containing organopolysiloxane (C), and a polyisocyanate (D), wherein the active-hydrogen-group-containing organopolysiloxane (C) contains an active-hydrogen-group-containing organopolysiloxane (C-1) having a carbinol group at only one terminal.

A fiber formed from a resin comprising a silicone-modified polyurethane resin comprising the reaction product of a polyol (A), a chain extender (B), an active hydrogen-containing organopolysiloxane (C), and a polyisocyanate (D), the active hydrogen-containing organopolysiloxane (C) containing an active hydrogen-containing organopolysiloxane (C-1) having a carbinol group only at one end, wherein
- the fiber has fiber diameter of less than 1,000 nm, and
- the active hydrogen-containing organopolysiloxane (C) further contains an organopolysiloxane (C-2) having the following formula (3):
- R8SiR2R3O(SiR2R3O)mSiR2R3R8 (3)
- wherein R2 and R3 are as defined above, R8 is each independently a C1-C10 monovalent hydrocarbon which has a hydroxyl or mercapto group and may have an oxygen atom intervening in the chain, or a C1-C10 monovalent hydrocarbon group having a primary or secondary amino group, and m is an integer of 1 to 60.
