چکیده

امروزه با رشد آگاهی در زمینه محیط‌زیست و تأکید بیشتر بر فرآیندهای پاک، استفاده از رنگزاهای طبیعی مورد توجه بسیاری قرارگرفته است. در این پژوهش رنگزای میکروبی فیکوسیانین به عنوان یک رنگزای طبیعی برای رنگرزی نخ های پشمی استفاده شد. به منظور بهبود خواص رنگی کالای پشمی، از اصلاحات سطحی پلاسمای تحت خلا، پرتو فرابنفش و همچنین دندانه زیستی کیتوسان استفاده شد. برای بررسی اصلاحات انجام شده، ثبات‌های شستشویی، نوری، مالشی، قدرت رنگی و فعالیت ضدمیکروبی نمونه‌ها مورد بررسی قرار گرفت. همچنین، به منظور بررسی گروه‌های عاملی و ریخت‌شناسی الیاف از طیف‌سنجی فروسرخ (FTIR) و میکروسکوپ الکترونی روبشی (SEM) استفاده شد. نتایج نشان داد، بیشترین قدرت رنگی (8.69) مربوط به نمونه اصلاح سطحی شده با فرابنفش و دندانه داده شده با دی کرومات پتاسیم است. همچنین، همه نمونه‌های رنگرزی شده فعالیت ضدمیکروبی عالی از خود نشان دادند.

چکیده [English]

Today, with the growing environmental consciousness and focus on eco-friendly processes, natural dyes are attracting considerable attention. This investigation employed Phycocyanin, a microbial dye, to naturally dye wool fibers. Methods such as plasma under vacuum, UV radiation surface modifications, and the use of chitosan bio-mordant were employed to enhance the color properties of wool products. The study assessed surface modifications, washing, light and rubbing fastness, color strength, and antimicrobial properties of the samples. Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to examine the functional groups and morphology of the fibers. Findings revealed that the sample treated with UV radiation and potassium dichromate mordant achieved the highest color strength (8.69). Additionally, all dyed samples exhibited notable antimicrobial effectiveness.
