1.Classified nekugadzirisa teknolojia
Fiber yakagadziridzwa inogadzirwa neshinda dzechisikigo (cotton linters, huni, bamboo, hemp, bagasse, tsanga, nezvimwewo) kuburikidza neimwe kemikari maitiro uye kutenderera kuumba patsva mamorekuru e cellulose, anozivikanwawo semafibisi akagadzirwa nevanhu. Nekuti iyo kemikari kuumbwa uye chimiro chemakemikari zvinoramba zvisina kuchinjika panguva yekugadziriswa, kugadzira uye kutenderera kwezvinhu zvakasikwa, inonzi zvakare regenerated fiber.
Kubva pane zvinodiwa zvekugadzirisa uye kudzoreredza kushatiswa kwemaitiro ekuchengetedza kwezvakatipoteredza, inogona kukamurwa kuita isiri-yekuchengetera nharaunda (cotton / huni pulp indirect dissolution method) uye kuchengetedzwa kwezvakatipoteredza (cotton / huni pulp yakananga dissolution nzira). Iyo isiri-yemamiriro ekudzivirira maitiro (yakadai seyechinyakare viscose Rayon) ndeye sulfonate iyo alkali-yakagadziriswa donje / yehuni pulp ine kabhoni disulfide uye alkali cellulose kugadzira inotenderera stock solution, uye pakupedzisira kushandisa yakanyoro kuruka kuti idzore Yakagadzirwa ne cellulose. coagulation.
Tekinoroji yekudzivirira kwezvakatipoteredza (yakadai se lyocell) inoshandisa N-methylmorpholine oxide (NMMO) aqueous solution se solvent kunyungudutsa zvakananga cellulose pulp mumushonga wekutenderera, wozougadzira nekunyorova kuruka kana kuruka kwakaoma-kunyorova kwakagadzirwa. Kuenzaniswa neyekugadzira nzira yeyakajairwa viscose fiber, mukana mukuru ndewekuti NMMO inogona kunyungudutsa zvakananga cellulose pulp, maitiro ekugadzira ekutenderera dope anogona kurerutswa zvakanyanya, mhinduro yekudzoreredza mwero inogona kusvika kupfuura 99%, uye maitiro ekugadzira haatombosvibisa. zvakatipoteredza. Maitiro ekugadzira eTencel®, Richel®, Gracell®, Yingcell®, bamboo fiber, uye Macelle ese maitiro ane hushamwari kwezvakatipoteredza.
2.Kuronga nemaitiro makuru emuviri
Zviratidzo zvakakosha zvakadai se modulus, simba, uye crystallinity (kunyanya pasi pemvura) zvinhu zvakakosha zvinokanganisa kutsvedza kwejira, kupenya kwemvura, uye kudonha. Semuenzaniso, yakajairwa viscose ine yakanakisa hygroscopicity uye nyore kudhaya midziyo, asi modulus yayo uye simba zvakaderera, kunyanya kunyorova kwesimba kwakadzikira. Modal fiber inovandudza zvikanganiso zvataurwa pamusoro apa zveviscose fiber, uye inewo simba rakakwirira uye modulus mumamiriro ekunyorova, saka inowanzonzi yakakwirira wet modulus viscose fiber. Mamiriro eModal uye dhigirii repolymerization ye cellulose mumorekuru akakwira kupfuura iyo yakajairwa viscose fiber uye yakaderera pane iyo yeLyocell. Iro jira rakatsetseka, pamusoro pejira racho rinopenya uye richipenya, uye kudhiroka kuri nani pane kwedonje riripo, polyester, uye rayon. Iine sirika-yakafanana nekupenya uye inonzwa, uye ndeye yakasikwa mercerized jira.
3.Mitemo yeMazita ekutengeserana kweRegenerated Fibers
Iyo yakasvibira uye inoshamwaridzana yakakwira-mwando modulus yakagadziridzwa selulosi zvigadzirwa zvakagadziridzwa munyika yangu zvinotevera mimwe mitemo maererano nemazita ezvigadzirwa. Kuti vafambise kutengeserana kwenyika dzese, vanowanzova nemazita echiChinese (kana Chinese pinyin) nemazita echiRungu. Kune maviri makuru mapoka emazita matsva egirinhi viscose fiber zvigadzirwa:
Imwe ndeyeModal (Modal). Zvinogona kunge zvakangoitika kuti Chirungu "Mo" chine mataurirwo akafanana neachiChinese "huni", saka vatengesi vanoshandisa izvi kushambadzira "Modal" kusimbisa kuti faibha inoshandisa huni hwechisikigo seyakasvibirira, inova chaizvo "Modal" . Nyika dzekunze dzinonyanya kushandisa matanda emhando yepamusoro, uye "Dyer" ndiko kududzirwa kwemabhii kuseri kwemutauro weChirungu. Kubva pane izvi, chero faibha ine "Dyer" mune zvigadzirwa zvenyika yedu yekugadzira fiber kugadzira makambani ndeyemhando iyi yechigadzirwa, iyo inonzi China Modal. : Zvakadai seNewdal (Newdal yakasimba viscose fiber), Sadal (Sadal), Bamboodale, Thincell, nezvimwe.
Chechipiri, mazwi eLyocell (Leocell) uye Tencel® (Tencel) anonyatsojeka. Zita rechiChinese reLyocell (lyocell) fiber yakanyoreswa munyika yangu nekambani yeBritish Acordis inonzi "Tencel®". Muna 1989, zita reLyocell (Lyocell) fiber rakatumidzwa neBISFA (International Man-made Fiber uye Synthetic Fiber Standards Bureau), uye iyo yakagadziridzwa cellulose fiber yakanzi Lyocell. "Lyo" rinobva pashoko rechiGiriki rokuti "Lyein", rinoreva kunyunguduka, ""sero" rinotorwa kubva muselulosi "Cellulose", maviri pamwe chete "Lyocell", uye homonym yekuChina inonzi Lyocell. Vatorwa vane nzwisiso yakanaka. yeChinese tsika pakusarudza zita rechigadzirwa, zita rechigadzirwa ndiTencel® kana "Tencel®".
