Polyester yog ua los ntawm kev siv tshuaj lom neeg nrog cov thee, roj av (los ntawm cov roj ), huab cua thiab dej. Raws li ib roj -raws li yas, polyester tsis biodegrade zoo li ntuj fibers. Tab sis nws nyob hauv qhov chaw pov tseg rau ntau xyoo lawm tsawg kawg - thiab muaj peev xwm ntau pua xyoo.

Tsis tas li ntawd, puas yog polyester ua los ntawm cov roj?

Polyester yog ib tug polymer, los yog ib tug ntev saw ntawm rov qab molecular units. Cov khoom siv ntau tshaj plaws yog polyethylene terephthalate, lossis PET, cov yas tau los ntawm cov khoom siv raw. roj uas yog siv los ua dej qab zib thiab ketchup fwj.

Tsis tas li ntawd, vim li cas thiaj li muaj ntau cov khaub ncaws ua los ntawm polyester? Vim tias nws yog ib qho tseem ceeb ntawm cov yas, hnav nws rau hnub kub txhais tau tias koj cov hws tau daig ntawm cov ntaub thiab koj cov tawv nqaij, ua rau koj kub dua. Tsis zoo li cov ntaub ntuj xws li paj rwb lossis ntaub plaub uas wick ya raws ntawm daim tawv nqaij thiab ua rau koj sim, polyester yuav cia koj damp. Los yog txawm poob nrog hws.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog polyester ua los ntawm?

Polyester yog ua li ntawm long-chain polymers. Synthetic polyester yog ua siv cov tshuaj tiv thaiv nrog cov thee, roj av, huab cua thiab dej. Cov khoom no yog ua li purified terephthalic acid (PTS) los yog nws cov dimethyl ester dimethyl terephthalate (DMT) thiab monotheluene glycol (MEG).

Dab tsi yog polyester sib xyaw?

Yuav pib nrog, ib tug poly-paj rwb sib tov Tsuas yog qhov nws lub npe qhia: ntaub uas yog ua los ntawm paj rwb thiab polyester fibers. Qhov sib piv sib txawv, nrog 65% paj rwb thiab 35% polyester ua qhov feem ntau. 50/50 sib tov kuj pom tau yooj yim.
