- An artificial leather is produced by impregnating a polymer elastomer in a non-woven fabric comprising three-dimensionally entangled ultrafine fibers, which is widely utilized in a variety of applications such as shoes, clothing, gloves, miscellaneous goods, furniture and automobile interior materials due to natural leather-like soft texture and unique appearance.
- Such artificial leather requires improved high functionality in terms of flexibility, surface quality properties, abrasion resistance, light resistance, elongation and the like according to applications and often requires a variety of properties.
- the artificial leather when used for a surface material adhered to an automobile sheet among the automobile interior materials, there is difficulty in that it satisfies surface quality properties, specifically, superior appearance, air-permeability and texture properties, as well as flame retardancy regulated by the Law among physical properties of automobile in accordance with increased expectation of consumers.
- the present invention is directed to an artificial leather capable of preventing problems caused by these limitations and drawbacks of the related art.
- an artificial leather that can exhibit a level of flame retardancy required in the art, is free of deterioration in soft texture of ultrafine fibers and has greatly improved air-permeability by partially coating a flame retardant composition on a preliminary artificial leather.
- an artificial leather comprising: a preliminary artificial leather comprising a non-woven fabric made of ultrafine fibers and an elastic polymer resin impregnated in the non-woven fabric; and a flame retardant composition layer formed on the preliminary artificial leather by partially coating a flame retardant composition thereon at an area ratio of 60 to 90%, with respect to the total area of the preliminary artificial leather.
- the present invention has the following effects.
- the artificial leather according to the present invention comprises a flame retardant composition layer that is partially coated at an optimal shape and content, thus advantageously exhibiting a level of flame retardancy required in the art and improving economical efficiency.
- the artificial leather according to the present invention can exhibit superior texture and air-permeability due to partial coating of the flame retardant composition layer.
- Such an artificial leather may be used for automobile sheets or the like, requiring superior flame retardancy, appearance and texture.
- preliminary artificial leather means an artificial leather, to which a flame retardant composition is not added, that comprises a non-woven fabric and an elastic polymer resin impregnated in the non-woven fabric.

- the flame retardant composition is only partially coated on the preliminary artificial leather 30
- grooves are formed in non-coated regions of preliminary artificial leather where the flame retardant composition is not coated and, as a result, the artificial leather of the present invention exhibit superior air-permeability without causing deterioration in texture of preliminary artificial leather made of fine fibers.
- the amount of flame retardant composition used can be greatly reduced since the flame retardant composition is only partially coated on the preliminary artificial leather 30. As a result, production cost of the artificial leather can be reduced and economic efficiency can be thus improved.
- the artificial leather of the present invention comprises a flame retardant composition layer 10 that is formed by partially coating the flame retardant composition at an area ratio of 60 to 90% with respect to the total area of the preliminary artificial leather 30.
- a flame retardant composition layer 10 that is formed by partially coating the flame retardant composition at an area ratio of 60 to 90% with respect to the total area of the preliminary artificial leather 30.
- the area ratio of the flame retardant composition layer 10 is lower than 60%, an artificial leather satisfying flame retardancy required in the art cannot be obtained, and when the area ratio of the flame retardant composition layer 10 is higher than 90%, air-permeability of the artificial leather may be greatly deteriorated.
- the flame retardant composition layer 10 may have a variety of shapes, as shown in FIGs. 1 and 3 to 5 .
- the flame retardant composition layer 10 may include a plurality of discontinuous unit layers having a predetermined shape. That is, the plurality of unit layers constituting the flame retardant composition layer 10 are discontinuously distributed on the preliminary artificial leather 30 and one groove 20 corresponding to the non-coated region of the preliminary artificial leather 20 surrounds the plurality of unit layers.
- the region where the preliminary artificial leather 20 is not coated may be readily burned along the continuously formed groove 20 and flame retardancy of artificial leather may be thus slightly deteriorated.
- a relatively great amount of flame retardant is inevitably used and, as a result, air-permeability and texture of artificial leather may be slightly deteriorated.
- the artificial leather of the present invention may include a plurality of grooves 20 that are discontinuously distributed in non-coated regions of preliminary artificial leather 30 to which the flame retardant composition is not coated.

- the upper part thickness (a) is preferably within a ratio range of 0.1 to 4% with respect to the thickness (c) of the preliminary artificial leather 30.
- the ratio of the upper part thickness (a) is lower than 0.1%, an artificial leather satisfying a level of flame retardancy required in the art cannot be produced, and when the ratio of the upper part thickness (a) is higher than 4%, the texture of artificial leather may be greatly deteriorated.
- the permeation depth (b) is preferably within a ratio range of 5 to 50% with respect to the thickness (c) of the preliminary artificial leather 30.

- the upper part thickness (a) and permeation depth (b) of the flame retardant composition layer 10 may be measured by imaging the cross-section of a sample with a scanning electron microscope (SEM).
- the flame retardant composition may comprise a flame retardant and a binder.
- a flame retardant a phosphorous-based flame retardant is preferred than a halogen-based flame retardant which is a cancer-inducing substance.
- the binder enhances adhesion force and may be selected from a variety of types of binders.
- a urethane-based binder containing silicon exhibits superior heat resistance due to presence of silicon, thus inhibiting decomposition of silicon during combustion, and can form a cross-linkage with urethane, thus improving flame retardancy of the artificial leather.
- the urethane-based binder advantageously has strong adhesion force with the preliminary artificial leather 30 as well as superior adhesion force with other material such as sponge.
- the flame retardant composition may comprise, in addition to the flame retardant and binder, a variety of additives.
- useful additives include an anti-oxidant, an anti-static agent, an ultraviolet ray absorbent, an anti-hydrolysis agent and a softening agent.
