Ea acetate. Production ya ea acetate faeba

Ka linako tsohle, indasteri Textile ke e mong oa mafapha bohlokoa ka ho fetisisa ea moruo naheng ea rōna, kaha e fana ka boemo nomoro ea tonanahali ea dinama tse nyenyane tse e le-ho hlokahala hore kamehla hlokahala eseng feela bakeng sa liaparo, empa esita le sebelisitsoe ka tlhahiso ea libetsa.

Le hobane hoo e ka bang ho tswa ho matsatsing a pele a ea Soviet Union pele litsebi tsa metsoako e ile fuwe mosebetsi wa ka ho hlahisa lisele tse maiketsetso, e le thepa tsa tlhaho hlile ba a haelloa. Ka lebaka leo, ho ile ha bōptjoa faeba ea acetate.
