Abstract

In this research, Carbon black particles were applied on the woven fabric by the knife coating technique and pretreatment using plasma corona discharge to build-up conductive cotton-polyester (CVC 50%) fabric electromagnetic shielding material. This paper describes the making of anti-radiation weaving fabric using plasma technology. The anti-radiation patch was developed by first modifying the textile fabric's surface using atmospheric pressure plasma technology using tip-cylinder electrode configuration. The plasma corona discharge was generated using high voltage electricity with asymmetrical electrodes (tip and cylinder). The treated weaving fabric using plasma was then coated with carbon black ink. This research indicates that an anti-radiation weaving fabric was successfully shielded electromagnetic radiation from an electronic device.

Abstract

Proses pengolahan limbah tekstil umumnya dapat berupa limbah dari proses penghilangan kanji (Desizing), penggelantangan (Scouring), pemutihan (Bleaching), dan pencelupan kain (Dyeing) serta proses pewarnaan dan pembilasan yang menghasilkan air limbah berwarna dengan COD yang tinggi. Dikarenakan kompleksitas jenis limbah tekstil, maka pemilihan metode pengolahan limbah merupakan suatu tantangan tersendiri dalam penelitian oleh beberapa peneliti. Artikel ini memperlihatkan beberapa metode pengolahan limbah dengan menggunakan metode elektrokoagulan (EC), metode plasma dan gabungan metode plasma dan elektrokoagulan. Hasil riset memperlihatkan bahwa pengabungan metode plasma dan elektrokoagulan akan lebih baik dalam penguraian air limbah dengan indikator menurunnya COD pada limbah (sebesar 240mgO2/L hingga 250 mgO2/L). Efisiensi pada metode plasma-elektrokoagulasi sebesar 42,5% - 44,8%.
