Kev tsim khoom ntawm eco- cov xov paj tus phooj ywg feem ntau pib los ntawm kev muab cov khoom siv raw, nrog rau qhov tseem ceeb ntawm kev rov ua dua tshiab lossis rov ua dua tshiab. Cov peev txheej muaj xws li cov raj mis yas rov siv dua, cov ntaub ntawv pov tseg, paj rwb spinning scraps, thiab ntuj, cov qoob loo ruaj khov. Siv cov polyester uas siv dua tshiab ua piv txwv, sau cov raj mis PET yog thawj zaug, ntxuav, thiab stripped ntawm cov ntawv lo thiab impurities; lawv mam li muab txiav rau hauv cov flakes huv si los yog chips los npaj rau cov txheej txheem spinning tom ntej.
Nyob rau hauv lub spinning theem, cov txheej txheem raw cov ntaub ntawv yog melted los yog yaj thiab ces extruded nyob rau hauv high kub los tsim zoo filaments. Rau cov khoom siv tshuaj fiber ntau, yaj spinning feem ntau yog siv: cov molten polymer yog extruded los ntawm ib tug spinneret mus rau hauv nruam filaments, uas yog ces txias, kos, thiab tshav kub- teem los xyuas kom meej cov fiber muaj qhov tsim nyog lub zog thiab stability. Ntuj eco- cov xov paj zoo nkauj, xws li paj rwb organic, tau dhau los ua cov txheej txheem spinning ib txwm muaj-xws li qhib, carding, kos duab, thiab zoo spinning-tab sis nrog txo cov tshuaj kho mob thaum lub sij hawm cog thiab ua tiav.
Raws li qhov xav tau ntawm daim ntawv thov, cov xov paj yuav raug twisting, dyeing, los yog kev kho kom zoo, xws li tshuaj tua kab mob, ya raws -wicking, los yog softening txheej txheem. Txhawm rau tswj hwm eco- cov qauv kev phooj ywg, dyeing feem ntau siv qis- cov pa phem dyes lossis dej-txuag cov txheej txheem. Cov eco tiav lawm- cov xov paj zoo tau txais kev kuaj xyuas zoo- ntsuas cov ntsuas xws li lub zog, sib xws, thiab xim nrawm- thiab tau pom zoo siv rau hauv kev xaws lossis xaws tsuas yog tom qab ua tau raws li cov qauv xav tau.
