Pencelupan Kain Rajut Kapas/Modal Menggunakan Zat Warna Reaktif Bifungsional Metoda One-bath

Indra Joshua, Samuel Martin Pradana, wiwiek eka mulyani

Sari


Zat warna reaktif bifuctional digunakan untuk mencelup kain rajut campuran Kapas/modal (65%/35%).  Perbedaan sifat daya serap kapas dan modal serta pengaruh konsentrasi natrium sufat dan natrium karbonat akan dibahas dalam penelitian ini.  Karakteristik hasil pencelupan dianalisa dengan pengujian K/S dan analisa terhadap ketahanan luntur warna setelah pencucian dengan menggunakan spektrofotometer.  Hasil penelitian menunjukkan terdapat pengaruh penggunaan konsentrasi natrium sulfat  dan natrium karbonat terhadap ketuaan warna dan kerataan warna tetapi tidak berpengaruh terhadap ketahanan luntur warna terhadap pencucian. Penggunaan natrium sulfat 50 g/l dan natrium karbonat 15 g/l dan pH larutan sebesar 11,7 pada suhu 60 0C selama 60 menit dapat menaikkan ketuaan warna serta dapat meningkatkan kerataan warna hasil pencelupan


Kata Kunci
