摘 要：Tubuliform silk glands were dissected from Nephila clavipes spiders,and silk gut fibers were produced by immersing the glands in a mild acid solution and subsequent *** tensile properties of the as produced fibers were obtained through tensile tests,and the stress–strain curves were compared with those of naturally spun tubuliform silk *** influence on the mechanical properties of the fibers after immersion in water and drying was also *** microstructure of the silk guts was obtained by X-ray diffraction(XRD) and infrared spectroscopy(FTIR).It was found that the stress–strain curves of the stretched tubuliform silk guts concur with those of their natural counterparts(tubuliform silk fibers).
