Abstract
Provided is an artificial leather that achieves both a soft texture and excellent durability, and a method for manufacturing the same, the leather comprising: a fibrous base material formed from superfine fibers having an average single fiber diameter of 0.1-10 μm; and a polymeric elastic body, where the polymer elastic body comprises a compound having a hydrophilic group and a compound having an ethylene oxide skeleton, the content of the compound in the polymeric elastic body of the artificial leather being 0.1-5 parts by mass per 100 parts by mass of the polymeric elastic body.
Claims3
An artificial leather comprising:
- a fibrous substrate formed of ultrafine fibers having an average single fiber diameter of 0.1 μm or more and 10 μm or less;
- and
- an elastomer,
- wherein the elastomer contains a compound having a hydrophilic group and a compound having an ethylene oxide skeleton represented by general formula (1) as below, and a content of the compound having the ethylene oxide skeleton in the elastomer of the artificial leather is 0.1 parts by mass or more and 5 parts by mass or less per 100 parts by mass of the elastomer,
- [Chemical formula 1]
- R1CH2CH2nR2 (1)
- wherein R1 and R2 are functional groups having 1 to 20 carbon atoms, and n represents the number of repeating units of 10 or more and 200 or less,
- wherein R1 in the general formula (1) is a functional group having an ester bond represented by general formula (2),
- wherein R3 is a functional group containing a terminal group selected from the group consisting of an isopropyl group, a tert-butyl group, and a mesityl group.
