Abstract
Disclosed are an artificial leather for crash pads and a crash pad manufactured using the same. The artificial leather for crash pads may have improved workability when workers directly cover a crash pad with the artificial leather for crash pads and require reduced manufacturing costs by using a textile substrate layer made of a circular knit fabric that satisfies a specific physical property range.
Claims14
An artificial leather for crash pads consisting essentially of:
- a textile substrate layer;
- a wet foaming layer disposed on the textile substrate layer;
- and
- an upper layer disposed on the wet foaming layer,
- wherein the textile substrate layer comprises a circular knit fabric and a polyurethane composite resin,
- wherein the circular knit fabric has an elongation in a longitudinal direction (L) of about 30 to 80% and an elongation in a width direction (W) of about 50 to 140% at a temperature of about 20 to 30° C., and
- wherein the circular knit has a tensile strength in the longitudinal direction (L) of about 20 to 70 kgf/cm and a tensile strength in the width direction (W) of about 20 to 50 kgf/cm at a temperature of about 20 to 30° C.
An artificial leather for crash pads consisting essentially of:
- a textile substrate layer;
- a wet foaming layer disposed on the textile substrate layer;
- an upper layer disposed on the wet foaming layer;
- and
- a napped layer on at least one surface of the textile substrate layer,
- wherein the textile substrate layer comprises a circular knit fabric and a polyurethane composite resin,
- wherein the circular knit fabric has an elongation in a longitudinal direction (L) of about 30 to 80% and an elongation in a width direction (W) of about 50 to 140% at a temperature of about 20 to 30° C., and
- wherein the circular knit has a tensile strength in the longitudinal direction (L) of about 20 to 70 kgf/cm and a tensile strength in the width direction (W) of about 20 to 50 kgf/cm at a temperature of about 20 to 30° C.
An artificial leather for crash pads consisting essentially of:
- a textile substrate layer;
- a wet foaming layer disposed on the textile substrate layer;
- an upper layer disposed on the wet foaming layer;
- and a non-napped layer on at least one surface of the textile substrate layer,
- wherein the textile substrate layer comprises a circular knit fabric and a polyurethane composite resin,
- wherein the circular knit fabric has an elongation in a longitudinal direction (L) of about 30 to 80% and an elongation in a width direction (W) of about 50 to 140% at a temperature of about 20 to 30° C., and
- wherein the circular knit has a tensile strength in the longitudinal direction (L) of about 20 to 70 kgf/cm and a tensile strength in the width direction (W) of about 20 to 50 kgf/cm at a temperature of about 20 to 30° C.
