콜라겐을 첨가한 폴리우레탄 코팅직물의 물성 = Physical properties of PU coated fabric with collagen

다국어 초록 (Multilingual Abstract)

The demand for PU coated synthetic leather is increasing as a high fashion material. But it has some faults of water vapor permeability, surface tacky property and static electricity. Therefore, the purpose of this study was the produce of PU coated fabric added collagen with hydrophilic property and soft touch. In the PU coated fabric, water vapor permeability, water vaper absorption and frictional electronic voltage were investigated, surface, bending and compression properties were also examined by the use of KES-FB System. The followings were the results of this study. 1. There was no Cr in the collagen, so that Cr was not treated in the collagen. 2. The surface and cross sectional layer of PU coated fabric with collagen were highly developed by micro porous structure. 3. The water vapor permeability of PU coated fabric was increased as collagen concentration increased. 4. The water vapor absorption of PU coated fabric was increased as collagen concentration increased. 5. The frictional electronic voltage of PU coated fabric was decreased in accordance with the increase of collagen concentration. Especially it effectivly decreased by the use of only 5% collagen concentration. 6. The bending and compression properties of PU coated fabric were increased in accordance with the increase of collagen concentration, so that it became stiff. 7. The Value of MIU, SMD was decreased in accordance with the increase of collagen concentration, so that the PU coated fabric became smooth.
