EVALUATION OF THE ECOLOGICAL PROPERTIES OF COTTON FABRIC AND SILK FABRIC DYED WITH COLORANTS EXTRACTED FROM THE TERMINALIA T. CATAPPA LEAVES
Abstract
This paper presents some results of the evaluation of the Ecological properties of cotton fabric and silk fabric dyed with colorants extracted from the Terminalia T. catappa leaves. The ecological criteria are standardized according Okotex: pH value of Cotton fabric is 6.2, of silk fabrics is 6.5; dyed fabric does not contain formaldehyde and azo Amin (are the carcinogenic substances and skin allergies), colorfastness to washing of both fabrics are fairly high (level 3-4 and 4), colorfastness to perspiration alkaline of silk grade 4-5, the Cotton grade 4; colorfastness to perspiration acidity of silk grade 4, of Cotton grade 3-4; on the fabric no heavy metals.
