1. Chii chinonzi bio-based fiber?
● Faibha dzakagadzirwa nezvinhu zvipenyu pachadzo kana kuti dzakatorwa kubva kuzvinhu zvipenyu.Semuenzaniso, polylactic acid fiber (PLA fiber) inogadzirwa kubva kune starch-ine zvigadzirwa zvekurima sechibage, gorosi, uye shuga beet, uye alginate fiber inogadzirwa nebrown algae.
● Mhando iyi yebio-based fiber haisi yakasvibirira chete uye yakasvibirira zvakatipoteredza, asi inewo kushanda kwakanakisisa uye kukosha kwakawedzerwa.Semuenzaniso, iyo mechanical properties, biodegradability, wearability, non-flammability, skin-friendly, antibacterial, uye mwando-wicking properties yePLA fibers haisi yakaderera kune yetsika dzechinyakare.Alginate fiber ndeyepamusoro-mhando mbishi zvinhu zvekugadzira yakanyanya hygroscopic zvekupfeka zvekurapa, saka ine yakakosha kukosha kwekushandisa mundima yekurapa uye yehutano.
2. Sei kuedza zvigadzirwa zvebiobased content?
Sezvo vatengi vachiwedzera kufarira zvakatipoteredza, zvakachengeteka, bio-sourced zvakasvibirira zvigadzirwa.Iko kudiwa kwemabio-based fibers mumusika wemicheka kuri kuwedzera zuva nezuva, uye zvakakosha kugadzira zvigadzirwa zvinoshandisa chikamu chepamusoro chezvigadzirwa zvebio-based kutora mukana wekutanga-mover mumusika.Zvigadzirwa zveBio-based zvinoda iyo bio-yakavakirwa zvemukati yechigadzirwa ingave iri mukutsvagisa nekusimudzira, kutonga kwemhando kana matanho ekutengesa.Biobased test inogona kubatsira vagadziri, vanogovera kana vatengesi:
● Chigadzirwa R & D: Kuongororwa kweBio-based kunoitwa mukugadzirwa kwezvigadzirwa zvebio-based, izvo zvinogona kujekesa zvinyorwa zvehupenyu huri muchigadzirwa kuti zvive nyore kugadzirisa;
● Kudzora kwemhando: Mukugadzira zvigadzirwa zvebio-based, bio-based bvunzo dzinogona kuitwa pane zvakapihwa zvigadzirwa kuti zvinyatso kudzora kunaka kwechigadzirwa zvigadzirwa;
● Kukurudzira uye kutengesa: Zvinyorwa zveBio-based zvichava chinhu chakanaka chekutengesa, chinogona kubatsira zvigadzirwa kuwana chivimbo chevatengi uye kubata mikana yemusika.
3. Ndingaziva sei iyo biobased content mune chigadzirwa?- Carbon 14 bvunzo.
Carbon-14 kuyedzwa kunogona kunyatso kusiyanisa bio-yakavakirwa uye petrochemical-yakatorwa zvikamu muchigadzirwa.Nekuti zvipenyu zvemazuva ano zvine kabhoni 14 muhuwandu hwakafanana nekabhoni 14 mumhepo, nepo petrochemical raw materials isina kana kabhoni 14.
Kana iyo bio-based test mhedzisiro yechigadzirwa iri 100% bio-based carbon content, zvinoreva kuti chigadzirwa chacho 100% bio-sourced;kana mhedzisiro yebvunzo yechigadzirwa iri 0%, zvinoreva kuti chigadzirwa chese petrochemical;kana mhedzisiro yebvunzo iri 50%, Zvinoreva kuti 50% yechigadzirwa ndeye biological mavambo uye 50% kabhoni ndeye petrochemical.
Mayedzo ekuyedza machira anosanganisira American standard ASTM D6866, European standard EN 16640, nezvimwe.
