Method for preparing medical complex fiber three-dimensional structure dressing

The invention relates to a method for preparing medical complex fiber three-dimensional structure dressing. PCL/RCSC hexafluoroisopropanol solution with mass concentration of 10% is used as spinning solution. Spinning is conducted on an electrostatic spinning-solution collecting device, spinning voltage is 10 kv, spinning distance is 10 cm, nanosilver solution of 4500 mg/L is used as bath solution, the adding rate of the bath solution is set according to spinning speed, newly spun nanofiber constantly makes contact with newly added nanosilver solution, so that PCL/RCSC complex fiber coated with nanosilver is obtained on a cellosilk receiving substrate, fiber is then reinforced three times with a pricking pin usually used in the non-woven process, soaked in distilled water for one minute so as to remove ethyl alcohol, and then dried for five days with a freezer dryer, and then the PCL/RCSC complex fiber three-dimensional structure dressing containing nanosilver is obtained. The obtained three-dimensional struc
