Abstract
The present invention provides a novel fiber suitable for an adsorbent for acidic gas. The fiber of the present invention includes a polymer having an amino group. With respect to the fiber, an adsorption amount of carbon dioxide when the fiber is caused to be in contact with mixed gas composed of carbon dioxide, nitrogen, and water vapor for 15 hours is 0.1 mmol/g or more, for example. Here, the carbon dioxide in the mixed gas has a concentration of 400 vol ppm, and the mixed gas has a temperature of 23° C. and a humidity of 50% RH.
Claims19
A fiber comprising a polymer having an amino group.
A production method for a fiber, the method comprising:
- discharging, from a discharge part, a raw material having a compound group including at least one selected from the group consisting of a monomer and a prepolymer, to send a discharge substance to a collection part;
- and
- applying, in a space between the discharge part and the collection part, energy to the compound group included in the discharge substance, to cause the compound group to react, thereby forming a polymer.
