Abstract

Kayu secang ( Caesalpinia sappan Linn) mengandung komponen kromofor brazilein yang dapat memberikan warna merah apabila dilarutkan dalam air. Tujuan penelitian adalah untuk melihat pengaruh proses ekstraksi maserasi dan perebusan dari kayu secang menggunakan pelarut air terhadap pewarnaan kain katun dan sutera. Hasil pewarnaan memberikan warna merah muda, merah keunguan, coklat dan coklat keabu-abuan. Pewarnaan kain sutera dengan ekstrak kayu secang yang menggunakan proses perebusan memberikan intensitas warna rata-rata yang lebih tinggi dibandingkan perlakuan lainnya, dengan ketahanan luntur warna yang cukup sampai sangat baik terhadap pencucian, keringat, sinar dan gosokan. abstract S appan wood (Caesalpinia sappan L.) contains a chromophore component of brazilein which can give red color when dissolved in water. The aim of the study was to see the effect of maceration and boiling extraction processes from sappan wood using water solvents on the dyeing of cotton and silk fabrics. The dyeing results g a ve pink, purplish red, brown and grayish brown. The dyeing of s ilk fabric with sappan wood extract using the boiling process provide d a higher average color intensity compared to other treatments, with color fastness for washing, perspiration, lighting, and rubbing were sufficient to excellent.
