The process of surface modification of silk fibers using plasma at atmospheric pressure.

Abstract

OCR 09WP 24 / 03 / 2569 The process of surface modification of silk fibers using plasma at atmospheric pressure consists of the following steps: Clean the degumming silk fibers. Then, feed the resulting silk bundles into a plasma winding machine. The silk fibers are wound at atmospheric pressure to improve their surface using a dielectric (DBD) atmospheric pressure plasma treatment. Barrier discharge (DBD) is combined with a plasma jet when the silk fibers undergo surface treatment. Plasma is used to continuously move silk fibers through a nano zinc oxide solution, resulting in a coating of the silk fiber surface. The silk fibers are then directed to move continuously through infrared heating tubes for drying. Soften the fabric before dyeing it with natural colors and then weaving it.

OCR 09WP 24 / 03 / 2569 1. The process of surface treatment of silk fibers using plasma at atmospheric pressure consists of the following steps: Preparation of silk fibers and surface treatment of silk fibers using roll-to-roll atmospheric pressure plasma. (To-Roll) consists of the following steps. a) Clean the surface of the silk fibers to prepare the workpiece before surface treatment with plasma at pressure. The atmosphere created by blowing clean air onto the silk threads. b) The silk threads are fed into a roll-to-roll plasma machine at atmospheric pressure. Atmospheric pressure plasma) c) Surface treatment of silk fibers using atmospheric pressure dielectric plasma (DBD). Barrier discharge (DBD) is combined with a plasma jet by feeding argon gas into the plasma generator. Under open air conditions, the argon gas flow rate is set at 0.5 to 5 liters per minute (lpm). And this causes air to be trapped between the power electrode, the dielectric layer, and the ground terminal. The ground electrode splits into plasma at a power of 20-200 watts and a frequency of 50-100 kHz. The maximum voltage (Vp-p) is 5-8 kilovolts and the temperature is 30-35 degrees Celsius.
