چکیده
به‌دلیل طبیعت اشتعال‌پذیر منسوجات سلولزی و صدمات غیرقابل جبران ناشی از آن بهبود مقاومت حرارتی کالاهای سلولزی امری ضروری می‌نماید. یکی از شیوه‌های شناخته شده‌ای که منجر به بهبود مقاومت حرارتی کالاهای سلولزی می‌شوند، استفاده از ترکیبات نیتروژن‌دار هستند. بر‌این‌اساس، در این پژوهش برای افزایش مقاومت حرارتی کالای سلولزی ویسکوز از نانوساختار دندریمر پلی‌آمیدو‌آمین حاوی گروه‌های نیتروژن (PAMAM-NH2) به‌همراه اتصال‌دهنده سیتریک اسید (CA) استفاده شده است. نتایج طیف‌سنجی‌های FTIR و ATR-FTIR تشکیل پیوندهای استری (-COO-) و آمیدی (-CONH-) شکل‌گرفته مابین گروه‌های عاملی ویسکوز، سیتریک اسید و نانوساختار دندریمر را تأیید می‌کنند. همچنین، تصاویر SEM همراه با آنالیز EDS حضور دندریمرها بر روی کالای ویسکوز اصلاح شده را نشان می‌دهند. افزایش مقاومت حرارتی و تأخیر در انتشار شعله نیز توسط آنالیزهای حرارتی شناخته شده TGA، DSC، LOI و تست عمودی سوختن تأیید شده است. نتایج نشان می‌دهد که حداقل میزان اکسیژن (LOI) مورد نیاز برای اشتعال‌پذیری ویسکوز خام از 2/18% به مقادیر 5/23% و 1/25% به‌ترتیب برای ویسکوز اصلاح شده با دندریمر نسل دوم و چهارم افزایش یافته است. علاوه‌بر‌این، نتایج وزن‌سنجی گرمایی (TGA) بیانگر آنست که میزان باقیمانده نهایی ویسکوز خام از 4/0% به 3/27% (ویسکوز اصلاح شده با دندریمر نسل دوم) و 4/29% (ویسکوز اصلاح شده با دندریمر نسل چهارم) تغییر یافته که منجر به سریع‌تر شدن اختناق حرارتی می‌شود. نتایج ارزیابی خصوصیات فیزیکی نیز حاکی از آنست که میزان

چروک‌پذیری، شاخص زردی، نیروی پارگی و طول خمش ویسکوز اصلاح شده در مقایسه با نمونه شاهد افزایش و در مقابل، میزان سفیدی و جذب رطوبت کاهش یافته است.

چکیده English

Due to the flammable nature of cellulosic textiles and the irreparable damage they cause, it is essential to improve their thermal resistance further. The application of nitrogen-containing compounds is one of the well-known methods to enhance the heat resistance of cellulosic products. Accordingly, in this study, a nanostructure containing multiple nitrogen groups called polyamidoamine dendrimer (PAMAM-NH2) with citric acid (CA) has been used to increase the thermal resistance of viscose cellulose products. Results of FTIR and ATR-FTIR confirm ester (-COO-) and amide (-CONH-) bonds formed between the functional groups of viscose, citric acid, and the dendrimers. Also, SEM images and EDS analysis show the presence of dendrimers on the modified viscose. Thermal stability and flame retardancy of the modified viscose were confirmed by well-known thermal analyses, TGA, DSC, LOI, and flammability test (in vertical configuration). The results show that the limiting oxygen index (LOI) of raw viscose has increased from 18.2% to 23.5% and 25.1% for viscose modified with G2- and G4-generation PAMAM dendrimers, respectively. In addition, TGA results indicate the final residual amount of raw viscose has enhanced from 0.4% to 27.3% (Viscose-CA-G2-PAMAM) and 29.4% (Viscose-CA-G4-PAMAM), which leads to faster thermal choking. In addition, the results of physical property evaluation show that the wrinkling resistance (WRA), yellowness index (YI), breaking strength (BS), and bending length (BL) of the modified viscose increased compared to the control sample; in contrast, the whiteness index (WI) and moisture decreased.
