The activated carbon as anti-odour coated and pigment printed fabric

Abstract

The different amount of activated carbon of 5%, 10% and 15% from coconut and oil palm shells in powder form were applied to the polyester and cotton fabrics by pigment printing and coating technique to investigate their anti-odour properties. The treated fabrics were exposed to onion odour for 24 hours before the odour tests were conducted. The odour tests were conducted to measure the effectiveness of treated fabric according to ISO Standards and making use of Portable Electronic Nose 3 (PEN 3) device. The results showed that, fabrics containing activated carbon are able to reduce odour that was picked up by the fabrics. The coated activated carbon fabrics gave better result than the printed activated carbon fabrics. The higher concentration of activated carbons on the fabrics generated lower rating of odour intensity and odour annoyance which also lower the odour of onion on the fabrics.
