استخدام الإنزيمات لتحسين خصائص الألوان للأقمشة المخلوطة (قطن بوليستر)‎ المصبوغة بصبغة طبيعية مستخلصة من التوت

الملخص EN

The world is turning recently to the use of biotechnology to protect the environment and improve the functional properties of products.

The use of enzymes is one of the most important applications of biotechnology in the fields of textile industries.

Therefore, this research was concerned with studying the effect of enzymes on the color characteristics of the natural dyeing of fabrics "50% cotton - 50% polyester".

Dye was extracted from the mulberry plant at different concentrations (65% -75% -85% ) and then dyed with fixation using two types of mordant: copper sulfate at conc.

(0.1-0.2-0.3 g) and alum at a conc.

2 g, the treatment with cellulase enzyme before and after dyeing, then making colorimetric measurements: (L*a*b*c*), (K/S) and color fastness tests (light - rubbing - washing - perspiration), The results indicated that Enzyme treatment (before dyeing) leads to a noticeable increase in (K/S), and Enzyme treatment (both before and after dyeing) gives an increase in the rate of color fastness for both light and rubbing (dry and wet) and washing, while it did not have a noticeable effect on the stability of perspiration (acid and alkaline), Hence, the researcher recommends more applied studies on activating the role of enzymes and using safe, natural dyes in textile dyeing to obtain environmentally friendly products
