This work was started by weft-knitting of an inner layer of such stent using polydioxanone （PDO） and silkf＇dment. Subsequently, 5-fluorouracil （5-FU） and curcnmin（CUR） loaded silk fibroin （SF） membranes were coated on the surface of the weft- knitted stent using electro-spinning technique to endow the drug delivery funct/on of the stent. The results show that the radial compression strength and c/renmferentlal expanding strength can reach above （9.1±0.4） cN/cm2 and （205.0± 0.2） cN/mm, respectively. The drug releasing behaviors can be sustained for 400 h. It is concluded that the stents have potential application as anintestinal stent in the future.展开更多

Through the measurement and analysis on the loop deformation of various samples, it is concluded that the problem herein mentioned would be improved to a certain extent by changing the fabric density or mixknitting from yarn with different direction of twist.展开更多

By testing the fiber properties, fiber spinnability is analysed. Modacrylic fibers with silk protein are brittle and have poor cohesion, so the key to process modacrylic fibers with silk protein lies in forming lap and sliver. During opening and carding, low speed is used to decrease fiber damage and the proper static resistant oil is applied to eliminate lapping fibers. Besides, the temperature and relative humidity have to be strictly controlled. The applications of modacrylic fibers with silk protein are also put forward.展开更多
