Abstract
A seat molded article and a method of preparing a seat molded article are disclosed. The seat molded article includes: an upper pad formed of polyurethane foam having a thickness in a range of 25 to 50 mm; and an elastic fabric disposed under the upper pad, wherein, in the elastic fabric, a difference in tensile elongation between warp and weft directions is 5.0% or less, and a tensile elongation measured under a load of 20 kgf is in a range of 20 to 40% in the warp and weft directions.
Claims16
A seat molded article comprising:
- an upper pad comprising polyurethane foam having a thickness in a range of 25 to 50 mm;
- and
- an elastic fabric disposed under the upper pad,
- wherein the elastic fabric comprises elastic monofilaments having a thermoplastic polyester elastomer resin as yarn,
- wherein the thermoplastic polyester elastomer resin comprises a hard segment and a soft segment,
- wherein the soft segment of the thermoplastic polyester elastomer resin comprises 10-50 wt. % of a total weight of the thermoplastic polyester elastomer resin,
- wherein, in the elastic fabric, a difference in a tensile elongation between a warp direction and a weft direction is 5.0% or less, and
- wherein the tensile elongation, measured under a load of 20 kgf, is in a range of 20 to 40% in the warp direction and the weft direction.
A method of preparing a seat molded article, the method comprising:
- preparing a polyurethane foam having a thickness in a range of 25 to 50 mm;
- preparing an elastic fabric;
- and
- disposing the elastic fabric under the polyurethane foam,
- wherein the preparing of the elastic fabric comprises:
- weaving the elastic fabric from yarn comprising a thermoplastic polyester elastomer resin in which a hard segment and a soft segment are polymerized;
- scouring the elastic fabric at a temperature in a range of 90 to 95° C.;
- and
- heat-treating the scoured elastic fabric at a temperature in a range of 150 to 165° C.
