The invention discloses an extraction and cleaning production process of apocynum venetum bast fibers. The extraction and cleaning production process comprises the following steps of soaking and washing the collected apocynum venetum bast part, then taking out the apocynum venetum bast, beating, taking out the beaten apocynum venetum bast, placing the beaten apocynum venetum bast in hot water for heat preservation, continuously adding an oxidizing agent into the hot water during the period, cleaning the apocynum venetum bast with the hot water, carrying out biological decomposition degumming, taking out the apocynum venetum bast, washing the apocynum venetum bast with the clear water, dehydrating the cleaned apocynum venetum bast, placing the apocynum venetum bast in the hot water again, continuously placing biological enzyme for decomposition degumming, taking out the apocynum venetum fibers, carrying out dehydration again, carrying out oil feeding, and fluffing the apocynum venetum fibers and then carrying
