ʻO nā kumu nui ʻelua o ka rayon he ʻaila a me nā kumu olaola.ʻO ka fiber regenerated he rayon i hana ʻia mai nā kumu olaola.Hoʻomaka ka hana ʻana i ka mucilage me ka unuhi ʻana o ka alpha-cellulose maʻemaʻe (ʻike pū ʻia ʻo pulp) mai nā mea cellulose maka.Hoʻohana ʻia kēia pulp me ka soda caustic a me carbon disulfide e hana ai i ka cellulose sodium xanthate ʻalani, a laila hoʻoheheʻe ʻia i loko o ka solution sodium hydroxide diluted.Hana ʻia ka ʻauʻau coagulation me ka sulfuric acid, sodium sulfate, a me ka zinc sulfate, a kānana ʻia ka mucilage, hoʻomehana ʻia (hoʻokomo ʻia i kahi mahana i ʻōlelo ʻia no kahi o 18 a 30 mau hola e hōʻemi i ka esterification o cellulose xanthate), defoamed, a laila pulu. wili.I loko o ka ʻauʻau coagulation, ka sodium cellulose xanthate decomposes me ka sulfuric acid, e alakaʻi ana i ka cellulose regeneration, precipitation, a me ka hana ʻana o ka cellulose fiber.

Me nā hiʻohiʻona hydrophilic (11% moisture hoʻihoʻi), ʻo ka rayon viscose he mea maʻamau i ka lole hana kaumaha me ka ikaika maʻamau a maikaʻi a me ke kūpaʻa abrasion.Me ka mālama pono ʻana, hiki ke hoʻomaʻemaʻe ʻia kēia fiber a holoi ʻia i ka wai me ka ʻole o ka uila a i ʻole pilling, ʻaʻole ia he kumukūʻai.
Nā pōʻino
ʻAʻole maikaʻi ka elasticity a me ke kūpaʻa o Rayon, ʻemi nui ia ma hope o ka holoi ʻana, a maʻalahi hoʻi ia i ka pala a me ka maʻi.Nalo ʻo Rayon i ka 30% a i ka 50% o kona ikaika ke pulu, no laila pono e mālama i ka wā e holoi ai.Ma hope o ka maloʻo ʻana, hoʻihoʻi ʻia ka ikaika (hoʻomaikaʻi viscose rayon - high wet modulus (HWM) viscose fiber, ʻaʻohe pilikia.

ʻO nā noi hope loa no ka rayon aia ma ke kahua o ka lole, upholstery, a me ka ʻoihana.ʻO nā laʻana e like me nā pāpale wahine, nā pālule, nā ʻaʻahu lalo, nā ʻaʻahu, nā lole e kau ana, nā lāʻau lapaʻau, nā mea ulana ʻole, a me nā mea maʻemaʻe.

ʻO ka siliki artificial he ʻōlinolino, he ʻano ʻano paʻakikī, a me kahi ʻano pulu a me ke anuanu.Ke kulu ʻia ʻo ia a ʻaʻole i ʻoki ʻia e ka lima, e ulu hou aʻe nā wrinkles.Ke palahalaha, paʻa nā laina.Ke hoʻomaʻemaʻe ʻia ka hope o ke alelo a hoʻohana ʻia e huki i ka lole, hiki ke maʻalahi a haki ka siliki hana.Ke maloʻo a pulu paha, ʻokoʻa ka elasticity.Ke hamo ʻia nā ʻāpana kilika ʻelua, hiki iā lākou ke hana i kahi kani ʻokoʻa.Ua ʻike ʻia ʻo Silk he "silk," a i ka wā e paʻa ai a hoʻokuʻu ʻia, ʻaʻole ʻike ʻia nā wrinkle.Loaʻa i nā huahana silika ka elasticity maloʻo a me ka pulu.
