mutu kulit dengan sistem radiasi kobalt-60 dilakukan dengan prosedur sebagai berikut:</p> <p class="MsoNormal" style="text-align:justify;line-height:150%">Kulit kras sapi Jawa kualitas C diimpregnasi dengan emulsi monomer n-butil akrilat (n-BA) dalam air atau dengan emulsi oligomer tripropylene glikol diakrilat (TPGDA) dalam air selama 2 jam, dimasukkan dalam kantong poliettilen dan diradiasi dengan sinar gamma kobalt-60 (dosis 5-25 kGy). Kulit yang sudah diradiasi dicuci dengan air, dikeringkan lalu diuji sifat fisisnya. Hasil uji sifat fisis menunjukkan bahwa: kuat tarik untuk kulit yang dicangkok dengan TPGDA menunjukkan kenaikan sedangkan kemolorannya menurun. Kuat tarik kulit yang dicangkok dengan n-BA ada yang naik dan ada yang turun demikian juga kemolorannya. Kulit modifikasi tahan terhadap bengkokan selama20.000 kali, sifat penyerapan airnya umumnya menurun, PHnya tetap, warnanya umumnya lebih gelap serta baunya lebih tajam. </p> <div align="justify"> </div> |
