Melemo
Ka litšoaneleho tsa hydrophilic (11% ea mongobo o khutla), rayon ea viscose ke lesela le sebetsang ho isa ho le boima le tloaelehileng ho matla a matle le ho hanyetsa abrasion.Ka tlhokomelo e nepahetseng, fiber ena e ka hloekisoa 'me ea hlatsuoa ka metsi ntle le motlakase o tsitsitseng kapa lipilisi,' me ha e theko e boima.

Mefokolo
Relasticity ea Rayon le ho tiea ha eona ha li ntle, e honyela haholo ka mor'a ho hlatsuoa, hape e hlaseleha habonolo ke hlobo le hlobo.Rayon e lahleheloa ke 30% ho isa ho 50% ea matla a eona ha e le metsi, kahoo tlhokomelo e tlameha ho nkoa ha e hlatsoa.Ka mor'a ho omisa, matla a tsosolosoa (viscose rayon e ntlafetseng - modulus e phahameng ea metsi (HWM) viscose fiber, ha ho bothata bo joalo).

Lisebelisoa
Likopo tsa ho qetela tsa rayon li maemong a liaparo, upholstery le indasteri.Mehlala e kenyelletsa litlhōrō tsa basali, lihempe, liaparo tsa ka tlaase, lijase, masela a leketlileng, litlhare, li-nonwovens le thepa ea bohloeki.

Phapang pakeng tsa rayon
Silika ea maiketsetso e na le sheen e khanyang, sebopeho se mahoashe hanyenyane le se thata, hammoho le maikutlo a mongobo le a batang.Ha e sosobane 'me e sa sosoe ka letsoho, e ba le masoba a mangata.Ha e bataletse, e boloka mela.Ha pheletso ea leleme e kolobisitsoe 'me e sebelisoa ho ntša lesela, silika ea maiketsetso e otloloha habonolo ebile e robeha.Ha o omme kapa o kolobile, elasticity e fapana.Ha likotoana tse peli tsa silika li hohla hammoho, li ka ntša molumo o ikhethang.Silika e boetse e tsejoa e le "silika," 'me ha e meneheloa ebe e lokolloa, masoebe ha a bonahale.Lihlahisoa tsa silika li boetse li na le elasticity e omileng le e metsi.
