Ma polypropylene nonwovens amagwiritsidwa ntchito m'magawo ambiri monga chithandizo chamankhwala, ukhondo, zida zodzitetezera (PPE), zomangamanga, ulimi, kunyamula, ndi zina. Komabe, ngakhale kuti zimathandizira miyoyo ya anthu, zimaikanso mtolo waukulu pa chilengedwe. Zimamveka kuti zinyalala zake zimatenga zaka mazana ambiri kuti ziwonongeke kwathunthu pansi pa zinthu zachilengedwe, zomwe zakhala zowawa m'makampani kwa zaka zambiri. Ndi chidziwitso chowonjezeka chachitetezo cha chilengedwe komanso kupita patsogolo kwaukadaulo wopanga mafakitale, makampani a nonwovens akugwiritsa ntchito zida ndi ukadaulo wokhazikika kuti achepetse kukhudzidwa kwa chilengedwe.
Kuyambira Julayi 2021, malinga ndi EU "Directive on Reducing the Environmental Impact of Certain Plastic Products" (Directive 2019/904), mapulasitiki owonongeka a oxidative akhala oletsedwa ku EU chifukwa chakuwonongeka kwawo kuti apangitse kuipitsa kwa microplastic.
Kuyambira pa Ogasiti 1, 2023, malo odyera, masitolo ogulitsa, ndi mabungwe aboma ku Taiwan, China adaletsedwa kugwiritsa ntchito tableware zopangidwa ndi polylactic acid (PLA), kuphatikiza mbale, zotengera za bento, ndi makapu. Mtundu wa kuwonongeka kwa kompositi wafunsidwa ndikukanidwa ndi mayiko ndi zigawo zambiri.
Kudzipereka ku kupuma kwamunthu wathanzi komanso kupereka mpweya wabwino ndi madzi,Medlong JOFOwapangaPP biodegradable nonwoven nsalu. Nsaluzo zitakwiriridwa m'nthaka, tizilombo todzipatulira timatsatira ndikupanga biofilm, kulowa ndikukulitsa unyolo wa polima wa nsalu yopanda nsalu, ndikupanga malo oswana kuti afulumizitse kuwonongeka. Panthawi imodzimodziyo, zizindikiro za mankhwala zomwe zimatulutsidwa zimakopa tizilombo toyambitsa matenda kuti titenge nawo mbali pa kudyetsa, kupititsa patsogolo kuwonongeka kwachangu. Kuyesedwa molingana ndi ISO15985, ASTM D5511, GB/T 33797-2017 ndi miyezo ina, nsalu ya PP yosawotcha yopanda nsalu imakhala ndi chiwopsezo chopitilira 5% mkati mwa masiku 45, ndipo yapeza chiphaso cha EUROLAB kuchokera ku bungwe lovomerezeka padziko lonse lapansi. Poyerekeza ndi chikhalidwe PPanapota zomangira nonwovens, PP biodegradable nonwovens akhoza kumaliza kuwonongeka mkati mwa zaka zingapo, kuchepetsa biodegradation mkombero wa zipangizo polypropylene, amene ali ndi tanthauzo zabwino kuteteza chilengedwe.
Nsalu za Medlong JOFO za PP zosawomba zowonongeka zimakwaniritsa kuwonongeka kwenikweni kwachilengedwe. M'malo otayira zinyalala zosiyanasiyana monga kutayira, m'madzi, m'madzi opanda mchere, sludge anaerobic, high solid solid anaerobic, ndi kunja kwachilengedwe, zitha kuonongeka mkati mwa zaka ziwiri popanda poizoni kapena zotsalira za microplastic.
M'mawonekedwe ogwiritsira ntchito, mawonekedwe ake, mawonekedwe ake, kukhazikika komanso moyo wautali ndi zofanana ndi nsalu zachikhalidwe zosalukidwa, ndipo moyo wake wa alumali sukhudzidwa.
Ntchito ikatha, imatha kulowa munjira yobwezeretsanso ndikusinthidwanso kapena kusinthidwa kangapo, zomwe zimakwaniritsa zofunikira zakukula kobiriwira, mpweya wochepa, komanso zozungulira.
