Kusvibiswa muindasitiri yemachira
● Sun Ruizhe, purezidhendi weChina National Textile and Apparel Council, akambotaura paClimate Innovation and Fashion Summit muna 2019 kuti indasitiri yemachira nembatya yave yechipiri pakukura indasitiri inosvibisa pasi rose, yechipiri chete kuindasitiri yemafuta;
● Maererano nemashoko kubva kuChina Circular Economy Association, anenge mamiriyoni makumi maviri nematanhatu ematani ehembe dzakasakara anokandwa mumagaba emarara munyika yangu gore negore, uye nhamba iyi ichawedzera kusvika mamiriyoni makumi mashanu ematani mushure me2030;
● Maererano nefungidziro yeChina National Textile and Apparel Council, nyika yangu inorasa marara gore negore, akaenzana nematani mamiriyoni 24 emafuta asina kuchena.Parizvino, zvipfeko zvekare zvakawanda zvichiri kuraswa nemarara kana kupisa, izvo zvese zvinokonzeresa kusvibiswa kwezvakatipoteredza.
Mhinduro kumatambudziko ekusvibiswa - bio-based fibers
Synthetic fibers mumachira anowanzo gadzirwa petrochemical mbishi zvinhu, senge polyester fiber (polyester), polyamide fibers (nylon kana nylon), polyacrylonitrile fibers (acrylic fibers), nezvimwe.
● Nekuwedzera kwekushomeka kwemafuta emafuta uye kumutswa kwevanhu vanoziva nezvekuchengetedzwa kwezvakatipoteredza.Hurumende dzakatangawo kutora matanho akasiyana-siyana ekuderedza kushandiswa kwemafuta uye kuwana mamwe mashandisirwo ezvekushandisa anogona kutsiva zvakatipoteredza.
● Zvichikonzerwa nekushomeka kweoiri uye matambudziko ezvakatipoteredza, makambani ekugadzira makemikari faibha echinyakare akadai seUnited States, European Union, neJapan zvishoma nezvishoma akasiya kugadzirwa kwekemikari yakajairwa, uye ave kushandisa ma bio-based fibers ayo ane pundutso uye asinganyanyi kukanganiswa. nezviwanikwa kana zvakatipoteredza.
Bio-based polyester zvinhu (PET/PEF) inogona kushandiswa mukugadzira bio-based fibers uyebiobased dehwe.
Mumushumo wazvino we "Textile Herald" pa "Ongororo uye Tarisiro yeWorld Textile Technology", zvakataurwa:
● 100% bio-based PET yakatungamira kupinda muindasitiri yezvekudya, sezvinwiwa zveCoca-Cola, chikafu cheHeinz, uye kurongedza zvigadzirwa zvekuchenesa, uye yakapindawo muzvigadzirwa zvefiber zvemhando dzinozivikanwa dzemitambo dzakadai seNike. ;
● 100% bio-based PET kana bio-based PEF T-shirt zvigadzirwa zvakaonekwa pamusika.
Sezvo kuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza kuri kuramba kuchiwedzera, zvigadzirwa zvebio-based zvichava nemabhenefiti emukati muminda yekurapa, chikafu uye hutano zvigadzirwa zvine hukama nehupenyu hwevanhu.
● Nyika yangu "Textile Indasitiri Development Plan (2016-2020)" uye "Textile Indasitiri "Yegumi Nemashanu-Yegore Chirongwa" Sainzi uye Tekinoroji Progress Outline yakaratidza zvakajeka kuti rinotevera basa rairo ndere: kugadzira itsva bio-based fiber zvinhu zvekutsiva. petroleum zviwanikwa, kusimudzira Industrialization yemarine bio-based fibers.
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.sekuti, tine kufona kutsva kwezvinhubiobased leather/vegan dehwe.
Sei uchiyedza zvigadzirwa zve biobased 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: Panguva yekugadzira 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.
Ndingaziva sei izvo biobased zviri muchigadzirwa?- 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.
