Treatment agent for treating fibers, fibers and production method therefor, and fiber sheet and production method therefor
The present invention relates to a treatment agent for treating fibers, the treatment agent comprising a condensation product of a liquid composition comprising at least one selected from the group consisting of a polysiloxane compound having a hydrolyzable functional group or a condensable functional group and a hydrolyzate of the polysiloxane compound having a hydrolyzable functional group.
1. A dried water-repellent fiber, comprising:
a fiber; and
a water-repellent portion on a surface to be treated of the fiber,
the water-repellent portion comprising a compound having a structure represented by the following formula (3):
wherein R 5 , R 6 , R 7 , R 8 each independently represent an alkyl group or an aryl group, a and c each independently represent an integer of 6 to 3000, and b represents an integer of 1 to 50,
wherein the water-repellent portion does not comprise an aerogel.
2. A water-repellent fiber sheet comprising the dried water-repellent fiber according to claim 1 .
3. The dried water-repellent fiber according to claim 1 , wherein, in following formula (3), a and c each independently represent an integer of 6 to 2000.
4. The dried water-repellent fiber according to claim 1 , wherein, in following formula (3), a and c each independently represent an integer of 10 to 1000.
