Environmentally tus phooj ywg, nqi-zoo thiab nyab xeeb, lub Regenerated polyester fiber ntau yog tsim los ntawm recycled yas fwj dej thiab ua kom sib npaug li 100% nkauj xwb polyester rau fills uas yog peb denier thiab loj dua.

Dhau li ntawm qhov no, cov fibers twg yog hu ua regenerated fibers?

Regenerated Fibers. Regenerated fiber yog tsim los ntawm dissolving lub cellulose thaj tsam ntawm cog fiber ntau nyob rau hauv tshuaj thiab ua rau nws mus rau hauv fiber dua (los ntawm viscose txoj kev). Vim nws muaj cellulose zoo li paj rwb thiab hemp, nws tseem hu ua "regenerated cellulose fiber ntau."

Tsis tas li ntawd, polyester fiber ua li cas? Polyester yog hluavtaws fiber ntau muab tau los ntawm thee, huab cua, dej, thiab roj av. Tsim nyob rau hauv lub 20th-xyoo pua lab, polyester fibers yog tsim los ntawm cov tshuaj tiv thaiv ntawm ib qho acid thiab cawv. Hauv cov tshuaj tiv thaiv no, ob lossis ntau lub molecules ua ke los ua ib qho loj molecule uas nws cov qauv rov ua dua thoob plaws nws qhov ntev.

Tsis tas li ntawd, dab tsi yog regenerated fibers ua los ntawm?

Regenerated fibers zoo ib yam li paj rwb, lawv yog thawj cov khoom tsim fibers kom tsim tau. Lawv yog ua los ntawm cellulose-raws li fibers uas yog los ntawm cov nroj tsuag xws li ntoo pulp; ib qho tshuaj ntxiv rau extract cov cellulose fibers.

Puas yog acetate Regenerated Fiber?

Acetate yog cellulose-derived fiber ntau tsis yog ib rov tsim dua tshiab cellulose fiber ntau . Nws yog tsim los ntawm acetylation cellulose siv acetic anhydride kua nrog sulfuric acid catalyst. Lub resulting cellulose acetate Nws yog yaj hauv acetone thiab spun rau hauv fiber ntau los ntawm cov txheej txheem qhuav spinning.
