Abstract
A moisture permeable protector such as gloves, fingerstalls, etc. for protecting hands and fingers at workshop, etc. utilizing a polyurethane film which has excellent moisture permeability. The film is made of polyurethane polymer having a polyoxyethylene content of 15-62% in a polyesterpolyol having a molecular weight of 3000 or less. The moisture permeability (g/m.sup.2,24 hours) of the film is 1500 or higher per 45 micron thickness, and the water absorption swelling ratio is 30% or less.
Claims2
A moisture permeable protector for protecting hands and fingers consisting of a polyurethane thin film having excellent moisture permeability and a low water absorption swelling ratio which is made of polyurethane polymer having a polyoxyethylene content of 15-62%;
- said polyurethane polymer being obtained by reacting a polyesterpolyol with an organic polyisocyanate in the presence of a chain elongation agent;
- said polyesterpolyol having a polyoxyethylene content of 17-70% and a molecular weight of 500-3000 and being obtained by reacting polyethyleneglycol having a molecular weight of 200-600 with organic dicarboxylic acid along or dicarboxylic acid and .epsilon.-caprolactone and/or short chain polyol.
