Modification of acrylic fabric by grafting silkworm chrysalis protein on it

For preparing a modified acrylic fabric with excellent wearability and biocompatibility,the acrylic fabric subjected to alkali weight reduction treatment was grafted with silkworm chrysalis protein(SCP) using sucrose fatty acid ester glycidyl ether(SFEGE)with softening function as crosslinking agent.The structure of the grafted acrylic fiber was characterized using SEM,infrared spectrum analysis and DSC,and the wearability of the grafted fabric was tested.The SEM image showed that the grafted fiber was covered with a layer of film;infrared spectrum analysis confirmed the grafting of chrysalis protein of the surface of the acrylic fabric;and DSC exhibited that the thermal stability of the grafted fiber has little change.The test of wearability indicated that the elasticity,softness and moisture permeability of the grafted acrylic fabrics still kept well,and the hygroscopic property and air permeability were improved.
