Polyester spunbond vs. polypropylene spunbond: chiwonetsero chachikulu kwambiri chaukadaulo pakusankha zinthu

Kuchita kwapakati: kusiyana kofunikira pamalingaliro obadwa nawo

1. Zida zamakina ndi kukhazikika

Polyester spunbond: Wopangidwa kuchokera ku poliyesitala (PET) ngati zopangira, mphamvu yolimba imatha kufika nthawi 1.5-2 kuposa ya polypropylene, ndi kusiyana kwamphamvu kwautali komanso kopingasa kochepera 5%, komanso kusunga mphamvu yopitilira 90% m'malo onyowa, oyenera kupsinjika kwanthawi yayitali. Kukana kwake kowala kumakhala kwachiwiri kwa acrylic fiber, ndipo pambuyo pa maola 1000 akuwonekera ndi kuwala kwa dzuwa, mphamvu zake zikhoza kusungidwa ndi 60-70%. Utumiki wake wakunja ukhoza kufika zaka zoposa 5. ku

Polypropylene spunbond: Kuchulukana kwapolypropylene (PP) zinthundi 0.91g/cm ³ zokha, zomwe zimapangitsa kukhala gulu lopepuka kwambiri pakati pa ulusi wamankhwala wamba. Makulidwe azinthu zolemera zomwezo ndi 30% kuposa polyester, ndipo fluffiness ndiyabwinoko. Koma ili ndi kukhazikika kosasunthika kwa kutentha, kufewetsa pa 70-80 ℃ ndi kusungunuka kosungunuka pamwamba pa 150 ℃. Ilinso ndi kukana kukalamba kofooka ndipo imakonda kukhala brittleness ikagwiritsidwa ntchito panja popanda chithandizo cha UV. ku

2. Kulekerera Kwamankhwala ndi Zachilengedwe

Polyester spunbond ili ndi kutentha kwanthawi yayitali kwa 260 ℃ ndi kutentha kwakanthawi kochepa kwa 300 ℃. Imalimbana ndi mankhwala, imalimbana ndi asidi, ndipo ilibe alkali, ndipo imayamwa chinyezi chosakwana 0.5%. Ndi antibacterial, njenjete umboni, ndi nkhungu umboni.

Polypropylene spunbond ili ndi kutentha kwanthawi yayitali kwa 120 ℃ ndi kutentha kwakanthawi kochepa kwa 150 ℃. Imalimbana ndi mankhwala, zidulo, alkalis, ndi zosungunulira zambiri za organic, zomwe zimayamwa chinyezi ≈ 0%. Ili ndi mayamwidwe apamwamba kwambiri komanso antibacterial properties, imapatula kukokoloka kwa bakiteriya ndikupeza bwino antibacterial properties.

3. Kusinthasintha kwa magwiridwe antchito

Polyester spunbond: Kachulukidwe kapamwamba kangathe kutheka kudzera pakulimbitsa zowotcha, ndipo kutulutsa mpweya kumatha kuwongoleredwa pakati pa 50-500L/m² · s, oyenera kusefa; Polypropylene spunbond: Zothamangitsira madzi zachilengedwe (makona olumikizana> 130 °), zitha kugwiritsidwa ntchito pamwamba pa zinthu zaukhondo pambuyo pa kusinthidwa kwa hydrophilic, ndi kuthamanga kwapakati kwa 0.3cm/s. ku

Makhalidwe a ndondomeko: kusiyanitsa zamakono kumapeto kwa kupanga

1. Kuyerekeza kwa magawo apakati ozungulira

Kutentha kwa polyester spunbond kupota ndi 285-290 ℃, kujambula liwiro ndi 4000-6000m/mphindi, wononga chiŵerengero cha phula kuyenera kukhala ≥ 27, zopangira zopangira ziyenera kukhala zouma (chinyezi <0.05%); Polypropylene spunbond 20 ⃃ 20-20-20-5 kutentha kwa 20 ℃ 20 ℃ 20 ℃, 272 ≥ 27 ≥272 2000m/mphindi, wononga m'mimba mwake chiŵerengero ndi 25-27 poyerekeza ochiritsira, ndi zopangira pretreatment sikutanthauza kuyanika.
ku
2. Zida ndi Kuwongolera Mtengo

Polyester spunbond: imafuna zida zowumitsa zapadera, zogwiritsa ntchito mphamvu 15-20% kuposa polypropylene, koma chomalizidwacho chimakhala ndi kulemera kwakukulu (± 2g/m²); Polypropylene spunbond: yogwirizana ndi 30% yowonjezera zinthu zobwezerezedwanso, kugulitsa zida ndi 10-15% kutsika, komanso kutentha kwapang'onopang'ono kotentha kosungunuka ndi 30% kuposa poliyesitala. ku

Momwe mungagwiritsire ntchito: malingaliro osankhidwa okhudzana ndi zofuna

1. Kugawikana kwa madera akuluakulu ofunsira

Chisankho chokondedwa chachitetezo chamankhwala ndipolypropylene spunbond(Mapangidwe a SMS), omwe ali ndi antibacterial amphamvu komanso opanda poizoni, komanso kusefera kopitilira 95%.

Polyester spunbond imakonda kusefedwa m'mafakitale chifukwa cha kukana kutentha kwambiri, kukula kwake kokhazikika, komanso kuthekera koyeretsedwa mobwerezabwereza.

Chisankho chomwe chimakondedwa pazaulimi ndi polypropylene spunbond (yosagwirizana ndi UV), chifukwa chachikulu ndichakuti kupota kwa polypropylene kumakhala ndi kukhuthala kowala, kutsika mtengo, ndipo kumatha kuwonongeka mwachilengedwe mkati mwa zaka 1-5.

Chisankho chomwe chimakondedwa chamkati mwagalimoto ndi polyester spunbond, chifukwa chachikulu ndikukana kukalamba, kutchinjiriza mawu abwino, komanso kukana kwanthawi yayitali kutentha kwambiri mpaka 120 ℃.

Chisankho chomwe chimasankhidwa pazaukhondo ndi polypropylene spunbond, chifukwa chachikulu ndichakuti polypropylene spunbond core imayamwa mwachangu, yothamangitsa madzi, komanso kukhudza kofewa.

2. Kusanthula kwachiwonetsero

Chovala chachipatala: chopangidwa ndi 30g/m² polypropylene SMS composite nsalu, yokhala ndi anti mowa ndi anti plasma properties, yokhala ndi chinyezi cha>2000g/m² · 24h;Chikwama chosefera kutentha kwambiri: Chopangidwa ndi 200g/m² polyester spunbond nsalu ndi yokutidwa mosalekeza ndi PT8 filimu yopangidwa ndi PT8FE ℃; Nsalu yotsimikizira udzu: 60g/m² Nsalu yolimbana ndi UV ya polypropylene spunbond, yokhala ndi mphamvu yong'ambika yodutsa kuposa 80N, komanso moyo wantchito mpaka zaka 3. ku

Economy ndi Market Pattern

1. Kuyerekeza kwamitengo (mwachitsanzo, 80g/m² mankhwala)

Mtengo wazinthu: tchipisi ta poliyesitala (8500 yuan/tani) vs tchipisi ta polypropylene (7200 yuan/tani), ndi tchipisi ta polypropylene kukhala 15.3% kutsika; Mtengo wokonza: Polyester (1.2 yuan/m²) vs Polypropylene (0.9 yuan/m²), Polypropylene ndi 25% kutsika; Mtengo wokwanira: Polypropylene spunbond ndi 18-22% kutsika kuposa poliyesitala. ku

2. Kugawana msika ndi zomwe zikuchitika

Pansalu yapadziko lonse ya spunbond nonwoven, polypropylene imatenga pafupifupi 70% ndipo poliyesitala imakhala 18%; Pazachipatala, kuchuluka kwa ma polypropylene SMS kapangidwe kachulukidwe kachulukidwe kuchoka pa 12% mu 2020 kufika pa 37.6% mu 2024, ndipo akuyembekezeka kupitilira 48% pofika 2025; Mu gawo la mafakitale,polyester spunbondlapeza chiwonjezeko chapachaka cha 8.2% pamsika wazosefera wotentha kwambiri chifukwa cha kukweza kwa magwiridwe antchito. ku

Chitetezo Chachilengedwe ndi Chitukuko Chokhazikika

Kubwezeretsanso: Zonsezi ndi zida za thermoplastic. Kubwezeretsanso poliyesitala kumafuna kutentha kwambiri kusungunuka (kugwiritsa ntchito mphamvu zambiri), pomwe kukonzanso kwa polypropylene kumafuna kutentha kochepa (30% kupulumutsa mphamvu). Komabe, mphamvu yosungira mphamvu ya polyester yobwezerezedwanso ndi 85%, yomwe ili yabwino kuposa ya polypropylene yobwezerezedwanso (70%);

Makhalidwe owonongeka: Polypropylene imatha kusiyanitsa zachilengedwe kwa zaka 1-5 powonjezera kuwonongeka kwa masterbatch, pomwe poliyesitala imafuna mikhalidwe yeniyeni ya enzymatic hydrolysis yokhala ndi kuwonongeka kwazaka zopitilira 20; ku

Mpweya wa carbon: Kupanga kwa polypropylene kumatulutsa pafupifupi matani 3.2 a CO ₂ pa tani, yomwe ndi yotsika kuposa polyester (matani 5.1 a CO ₂). ku

Ultimate Choice Guide

Chofunika kwambiri chiyenera kuperekedwa kwa polypropylene spunbond: pamene kufunika kuli kwa mtengo wotsika, wopepuka, wothamangitsa madzi, wotayika (monga masks, zinthu zaukhondo, chitetezo chokhalitsa); ku

Chofunika kwambiri chiyenera kuperekedwa kwa polyester spunbond: pamene kufunikira kuli kwamphamvu kwambiri, kukana kutentha kwakukulu, kukana kukalamba, ndi kugwiritsidwa ntchito kwa nthawi yaitali (monga zipangizo zosefera mafakitale, zomangira zakunja, ndi zamkati zamagalimoto); ku

Zochitika zapadera: Sankhani polypropylene SMS composite yotetezedwa ndimankhwala apamwamba, filimu ya poliyesitala yosefera kutentha kwambiri, ndi polypropylene yosamva UV kuti ifike kwaulimi kwanthawi yayitali. ku

Dongguan Liansheng Non Woven Technology Co., Ltd.idakhazikitsidwa mu Meyi 2020. Ndi bizinesi yayikulu yopanda nsalu yopanga nsalu kuphatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Itha kupanga mitundu yosiyanasiyana ya nsalu za PP spunbond zosalukidwa ndi m'lifupi mwake osakwana 3.2 metres kuchokera ku 9 magalamu mpaka 300 magalamu.
