Abstract    There is an increasing demand for air-dry performance of fluorocarbon finished materials. Thus, dyeing with different types of reactive, mono, bi, and multi-functional, dyes was evaluated as a novel treatment to create correct surface interface to maintain fluorocarbon performance without ironing or tumble drying. The effects of pre-treatment on fluorocarbon finishing of cotton fabric, a cellulosic polymer, was investigated by measuring wash fastness as well as 3M water repellency test and samples hot pressing. Fabrics mechanical properties were compared by measuring tensile strength. Also, the effect of the finishing on samples colour was studied. The results indicated that by dyeing with proper reactive dye not only the fastness and repellency properties can be improved, but also the molecular re-orientation of fluorocarbon polymers can reach fulfilment level for water repellency at ambient temperature. Further more, no negative effect on tensile properties and samples colour was observed.


Keywords    Fluorocarbon, Chain Re-orientation, Reactive dyes, Cellulosic substrate, Multi-functional dyes.


چکیده    امروزه تقاضای زیادی برای کالاهای تکمیل شده با ترکیبات فلوئورو کربنی که کیفیت اولیه دافعیت خود را در مرحله خشک شدن بازیابند وجود دارد. بهمین علت استفاده از رنگهای راکتیو تک ، دو، و چند عامله مورد ارزیابی قرارگرفت تا سطح مرزی ویژه ای بوجود آورند تا ترکیبات فلوئورو کربنی بدون هیچ عملیات حرارتی کارایی اولیه خود را حفظ کنند. تاثیر این عملیات مقدماتی بر خصوصیات پارچه پنبه ای ، پلیمر سلولزی، با اندازه گیری ثبات شستشویی، آزمون 3-ام و بررسی اثر عملیات گرمایی ارزیابی گردید. تغییر خواص مکانیکی کالا نیز با اندازه گیری استحکام کالا برسی شد. همچنین تاثیر عملیات تکمیلی بر ویژگیهای رنگی نمونه ها مطالعه گردید. نتایج مشخص می سازند که با رنگرزی نمونه ها با رنگ راکتیو مناسب نه تنها خواص ثباتی و دافعیت کالا بهبود مییابد بلکه تغییر آرایش یافتگی پلیمر فلوئورو کربنی به حدی خواهد رسید که کالای خشک شده در دمای محیط آبگریزی خود را حفظ میکند. همچنین مشخص گردید که این عملیات تاثیر منفی بر استحکام و خواص رنگی کالا ندارد.
