چکیده

یکی از روش‌های افزایش عمق رنگی منسوجات رنگرزی شده استفاده از مواد عمق‌دهنده رنگ می‌باشد. این مواد از طریق تشکیل فیلم و با داشتن ضریب شکستی کمتر از ضریب شکست الیاف با کاهش انعکاس سطحی در فصل مشترک الیاف و هوا، باعث درک بیشتر عمق رنگی می‌شوند. ترکیبات شیمیایی مختلفی با این هدف معرفی شده و بصورت تجاری بطور گسترده استفاده می‌شوند. یک عمق‌دهنده بایستی هم ضریب شکست پایینی داشته باشد و هم منجر به تغییر زیردست پارچه و تغییر رنگ احتمالی کالای رنگرزی شده نشود. اما همچنان تحقیقات در زمینه سنتز و شناسایی مواد جدید، نحوه آنالیز و تعیین قدرت عملکرد اینگونه مواد ادامه دارد. در تحقیق حاضر تلاش شده است، با تعریف مواد عمق‌دهنده رنگ مورد استفاده در تکمیل منسوجات رنگرزی شده، انواع، مکانیزم عملکرد و نحوه‌ی ارزیابی آن‌ها مرور شود.

چکیده [English]

One way to increase the color depth of dyed textiles is to use color deepening agents. Through film formation and having a refractive index less than the fiber refractive index, these materials reduce the surface reflection at the interface between the fibers and the air. This result gives a more perception of the color depth. Various chemical compounds are introduced and are widely used commercially for this purpose. A deepening agent should have a low refractive index and not lead to a change in the fabric's handle and color change on the dyed good. However, research continues on the synthesis and identification of new materials, the method to analyze them and determine the performance of such materials. In the present study, an attempt has been made by defining color deepening agents used in the finishing of dyed textiles, the types and mechanism of action, and how to evaluate these materials.
