Kev lag luam sib txawv ntawm cov ntaub tsis muaj ntaub spunlaced | JINHAOCHENG

Cov ntaub tsis-woven uas tsis yog spunlaced yog ib qho ntawm ntau cov ntaub tsis-woven. Peb feem ntau siv cov ntaub tsis-woven uas tsis yog spunlaced hauv peb lub neej txhua hnub, xws li cov ntaub so ntub, cov ntaub so huv, cov phuam ntsej muag pov tseg, daim ntawv npog ntsej muag thiab lwm yam. Cov ntsiab lus hauv qab no yuav qhia txog qhov zoo ntawm cov ntaub tsis-woven uas tsis yog spunlaced hauv kev ua lag luam.

Kev them nqi thoob ntiaj teb

Cov ntaub so ntswg uas tsis yog woven uas siv pov tseg tau siv rau cov ntaub so ntswg uas siv tau ntev thiab siv tau ntev. Feem ntau, cov khoom siv uas siv pov tseg tau loj hlob zoo txij li xyoo 2014, vim lawv yog cov khoom siv thib ob hauv kev lag luam loj, xws li cov ntaub so menyuam yaus thiab cov khoom siv tu cev rau poj niam. Cov khoom siv uas siv pov tseg tau feem ntau yog cov khoom tshwj xeeb thiab muaj cov nyiaj tau los ntau dua li cov khoom siv uas siv tau ntev.

Qhov kev thov kom muaj cov khoom siv pov tseg no los ntawm cov neeg hauv chav kawm nruab nrab thiab cov neeg xav tau hauv Asia ua rau nws yog lub khw loj tshaj plaws hauv cheeb tsam thiab cov neeg tsim khoom ntawm cov ntaub spunlaced nonwovens. Muaj 277 kab tsim khoom spunlace uas tau lees paub hauv Asia, nrog rau lub peev xwm tsim khoom ntawm kwv yees li 1070000 tons hauv xyoo 2019. Tuam Tshoj ib leeg muaj ze li ntawm 200 kab tsim khoom ntsia nrog lub peev xwm nameplate ntawm ntau dua 800000 tons. Qhov no yuav txhawb nqa kev loj hlob ntxiv ntawm kev thov rau yuav luag 350000 tonnes ntawm cov khoom spunlaced hauv Asia los ntawm 2024.

Plaub lub khw siv kawg

Kev nthuav dav thiab kev ua lag luam ntawm spunlacing yav tom ntej yuav raug tsav los ntawm kev hloov pauv ntawm kev xav tau ntawm cov neeg siv khoom, kev hloov pauv ntawm cov nqi khoom siv thiab kev tsim kho tshiab ntawm thev naus laus zis. Smithers cov kws tshaj lij kev tshuaj xyuas tau txheeb xyuas cov qauv kev lag luam tseem ceeb hauv qab no:

Cov ntaub so uas zoo rau ib puag ncig ntau dua

Kev siv cov ntaub so tes uas tsis yog ntaub spunlaced loj tshaj plaws yog cov phuam so tes. Qhov no suav txog 63.0% ntawm tag nrho cov kev siv spunlace hauv xyoo 2019, uas yuav luag ib nrab yog siv rau cov ntaub so menyuam yaus.

Cov ntaub tsis yog woven siv rau hauv cov ntaub so menyuam yaus feem ntau yog spunlaced vim lawv lub zog siab thiab mos, txawm hais tias lawv kim thiab tsis lwj tag.

Peb qhov kev tsim kho tshiab tshaj plaws hauv cov ntaub so menyuam yaus thoob ntiaj teb yog:

Cov khoom "rhiab heev" muag hauv cov tshuaj pleev ntuj tsis muaj ntxhiab, tsis muaj cawv, tsis ua rau ua xua, thiab tsis muaj zog.

Siv cov paj rwb rov ua dua tshiab ua cov khoom siv raw los txo tus nqi ntawm cov ntaub so paj rwb rov ua dua tshiab.

Cov neeg siv khoom tau pib paub txog Lesserky nonwovens rau cov ntaub ntawv yooj yim.

Qhov kev tsim kho tshiab tom ntej ntawm cov ntaub so menyuam yaus tej zaum yuav yog cov ntaub tsis yog woven uas ua los ntawm cov polymers bio-based. Cov chaw tsim khoom ntawm cov ntaub tsis yog woven tab tom sim nrog cov spunlaced ua los ntawm polylactic acid (PLA) thiab sib tham txog tus nqi zoo dua thiab sib xws dua rau cov fibers PLA.

Ntxuav tau

Qhov kev thov ntau heev rau cov ntaub so ntswg tsis ntev los no ua rau muaj ntau cov ntaub so ntswg uas ua haujlwm tau zoo thiab pheej yig rau cov ntaub so ntswg uas ntxuav tau - ib qho kev ua lag luam uas tau txwv los ntawm cov khoom siv uas yaj tau. Nruab nrab xyoo 2013 thiab 2019, tsawg kawg yog cuaj txoj kab tsim khoom tshiab uas tsis yog ntaub so ntswg tau muab tso rau hauv kev ua haujlwm, siv cov thev naus laus zis tshiab los ntxuav kev ua lag luam ntaub so ntswg tsis yog ntaub so ntswg.

Yog li ntawd, cov chaw tsim cov phuam da dej uas ntxuav tau tab tom nrhiav kev lag luam tshiab rau cov ntaub so uas ntxuav tau. Lub hom phiaj tseem ceeb ntawm kev siv tshuab yog los tsim cov thev naus laus zis niaj hnub los txhim kho kev sib kis thiab kev ntxuav tau. Yog tias cov khoom tuaj yeem tsim los kom ntxuav tau zoo li daim ntawv so quav, nws yuav zam tau cov teeb meem rau kev lag luam dej khib nyiab thiab tsoomfwv cov neeg tswj hwm.

Kev tu cev huv si

Kev Huv Huv yog ib qho kev lag luam tshiab rau spunlace. Nws feem ntau yog siv rau hauv daim ntaub qhwv pob ntseg elastic ntawm cov ntaub qhwv menyuam / cov ntaub qhwv menyuam thiab txheej thib ob ntawm cov khoom siv tu cev poj niam. Piv nrog rau kev tsim khoom spunbonded, nws qhov kev nkag mus yog txwv los ntawm kev tsim khoom thiab kev txiav txim siab tus nqi.

Kev ruaj khov yog qhov tseem ceeb dua rau cov khoom siv pov tseg. European Union tau txais nws cov lus qhia txog cov yas pov tseg thaum Lub Kaum Ob Hlis 2018. Cov ntaub so ntswg huv yog cov khoom siv huv uas nyob rau hauv nws daim ntawv teev npe thawj zaug. Cov chaw tsim khoom ntawm cov khoom noj qab haus huv kuj xav muag cov khoom siv ruaj khov rau cov neeg siv khoom uas paub txog ib puag ncig, txawm hais tias tus nqi yuav tseem yog qhov tseem ceeb ib yam li xyoo 2024.

Txhawb kom txhua tus neeg koom nrog kev ua lag luam los pab txhawb rau lub hom phiaj no:

Cov neeg muab khoom siv yuav tsum txheeb xyuas cov fibers thiab polymers uas ruaj khov dua thiab pheej yig dua rau cov ntaub tsis-woven.

Cov neeg muab khoom siv yuav tsum txo cov peev txheej los ntawm kev muab cov kab ntau lawm uas zoo tshaj plaws rau cov khoom siv tu cev uas tsis hnyav.

Cov chaw tsim khoom siv Spunlacing kuj tseem yuav tsum tsim cov khoom uas siv cov khoom siv raw tshiab no thiab cov txheej txheem zoo dua los tsim cov khoom siv huv uas pheej yig dua, mos dua thiab ruaj khov.

Cov neeg ua haujlwm muag khoom thiab kev lag luam yuav tsum txheeb xyuas cov cheeb tsam thiab cov pab pawg neeg siv khoom uas txaus siab them tus nqi siab rau cov khoom noj qab haus huv uas ruaj khov.

Kev ua tau zoo heev hauv kev kho mob

Lub lag luam loj thawj zaug rau spunlacing yog cov ntawv thov kho mob, suav nrog cov ntaub phais, cov khaub ncaws phais, cov pob CSR thiab cov ntaub qhwv qhov txhab. Txawm li cas los xij, ntau yam ntawm cov kev siv kawg no tam sim no tau hloov los ntawm cov ntaub tsis yog woven spinning.

Hauv qhov kev siv kawg no, spunlacing tsis zoo li yuav phim tus nqi ntawm spunlaced nonwovens; cov neeg yuav khoom kho mob uas tsom mus rau kev ua tau zoo thiab kev ruaj khov yuav tsum tau txheeb xyuas thiab koom nrog. Yuav kom nce kev siv spunlace hauv cov khoom kho mob, cov neeg muab khoom siv raw yuav tsum txheeb xyuas thiab muab cov khoom siv raw pheej yig, ruaj khov uas nqus tau thiab muab cov qauv nrog lub zog siab dua thiab elasticity dua li cov khoom spunlaced tam sim no.
