| titleOfInvention | Manufacturing Method of Leather for Sofa |
| abstract | The present invention relates to a method for producing natural leather for sofa, and more particularly, to a method for producing natural leather for sofa, which comprises unhairing a natural leather cut into a thickness of 5 mm by impregnating an aqueous calcium hydroxide solution having a mass concentration of 3 to 5% A first slurry step of removing the fat portion at a speed of 10 to 15 m / min using a band knife to avoid the thickness of 2.9 to 3.1 mm; A tanning step of mixing and tanning 10 to 25 parts by weight of an organic tanning agent comprising 75 to 85% by weight of glutaraldehyde and 15 to 25% by weight of phosphoric acid with respect to 100 parts by weight of the natural leather after the first slicing step; A second dipping step of avoiding the natural leather having undergone the tanning step to a thickness of 1.9 to 2.1 mm at a speed of 5 to 9 m / min using a shaving apparatus; An additive mixing step of mixing 3 to 6 parts by weight of acrylic sultin and 2 to 5 parts by weight of casein sultane with respect to 100 parts by weight of natural leather that has undergone the second slicing step; And adjusting the thickness of the natural leather through the additive mixing step to 0.6 to 0.7 mm using a splitting equipment; . The natural leather for sofa manufactured through the above process does not use a chromium component in the tanning step, so that harmful substances are not emitted to the human body, and it can exhibit excellent tensile strength and tear strength while being thin. |
