PROBLEM TO BE SOLVED: To provide a novel low friction composition for a seat belt, improving smooth handling property of the belt and friction property represented by a pull-in speed of the belt into a retractor.SOLUTION: A low friction composition for a seat belt contains polyether polyurethane, low molecular weight polyurethane having a free NCO group and containing an aliphatic chain, polyurethane having no free NCO group, polyethylene and polydimethylsiloxane. Further the low friction composition contains fluoroalkyl acrylate polymer and has an emulsion form dispersed in water. The seat belt coated by the composition is provided. |
