Non woven polypropylene vs polyester

Nsalu zosalukidwa si nsalu zolukidwa, koma zimapangidwa ndi ulusi wokhazikika kapena mwachisawawa, motero zimatchedwanso nsalu zosalukidwa. Chifukwa cha zinthu zosiyanasiyana zopangira ndi kupanga, nsalu zopanda nsalu zimatha kugawidwa m'mitundu yambiri, mongansalu za polyester zopanda nsalu, polypropylene sanali nsalu nsalu, etc.

Makasitomala nthawi zambiri amafunsa za kusiyana kwa nsalu za poliyesitala zosalukidwa, nsalu za polypropylene zosalukidwa, ulusi wa polypropylene, ndi poliyesitala akamafunsira zinthu zansalu zosalukidwa. Pansipa pali mndandanda wa kusiyana kwawo.

PET nsalu yopanda nsalu

Nsalu za PET spunbond filament zosalukidwa ndi mtundu wansalu wosalukidwa wopanda madzi, ndipo ntchito yake yochotsa madzi imasiyanasiyana malinga ndi kulemera kwa nsaluyo. Kukula ndi kukhuthala kwake, kumapangitsanso ntchito yabwino yothamangitsira madzi. Ngati pali madontho amadzi pamwamba pa nsalu zosalukidwa, madontho amadzi amatsika mwachindunji.

Nsalu ya polyester yosalukidwa imalimbana ndi kutentha kwambiri. Chifukwa cha kusungunuka kwa poliyesitala kukhala mozungulira 260 ° C, imatha kusunga kukhazikika kwakunja kwa nsalu zosalukidwa m'malo omwe amafunikira kukana kutentha. Zakhala zikugwiritsidwa ntchito kwambiri pakusindikiza kutentha, kusefera kwamafuta otumizira, ndi zida zina zophatikizika zomwe zimafuna kukana kutentha kwambiri.

PET spunbond nsalu yopanda nsalundi mtundu wa ulusi wosalukidwa wachiwiri kwa nayiloni spunbond wosalukidwa nsalu. Mphamvu zake zabwino kwambiri, kutulutsa mpweya wabwino, kukana kwamphamvu, kukana misozi ndi zinthu zotsutsana ndi ukalamba zagwiritsidwa ntchito m'magawo osiyanasiyana ndi anthu ochulukirapo.

Nsalu ya PET spunbond yosalukidwa ilinso ndi chinthu chapadera kwambiri: kukana kunyezimira kwa gamma. Ndiko kunena kuti, ngati atagwiritsidwa ntchito pazachipatala, cheza cha gamma chitha kugwiritsidwa ntchito mwachindunji popha tizilombo toyambitsa matenda popanda kuwononga mawonekedwe awo akuthupi ndi kukhazikika kwake, chomwe ndi katundu wakuthupi yemwe polypropylene (PP) spunbond yopanda nsalu alibe.

Nsalu ya polypropylene yopanda nsalu

Nsalu yopangidwa ndi spunbonded yopanda nsalu imatanthawuza ulusi wopitilira womwe umapangidwa ndi kutulutsa ndi kutambasula kwa ma polima, omwe amayikidwa mu ukonde. Ukonde umadzimangiriza pawokha, womangika, womangidwa ndi mankhwala kapena amalimbikitsidwa kuti asandutse ukonde kukhala nsalu zosalukidwa. Amagwiritsidwa ntchito pazinthu zaukhondo zotayidwa, monga zopukutira zaukhondo, mikanjo ya opaleshoni, zipewa, masks, zofunda, nsalu za thewera, ndi zina zambiri.

Non woven polypropylene vs polyester

PP ndi polypropylene yaiwisi yaiwisi, ndicho polypropylene CHIKWANGWANI, amene ndi woonda sanali nsalu nsalu; PET ndi chinthu chatsopano cha poliyesitala, chomwe ndi ulusi wa poliyesitala, wopanda zowonjezera pakupanga konse. Ndi chinthu chabwino kwambiri chogwirizana ndi chilengedwe ndipo ndi cha nsalu zochindikala zosalukidwa.

Kusiyana pakati pa polypropylene ndi polyester fibers

1, mfundo yopanga

Mfundo zopangira ulusi wa polypropylene ndi polyester ndizosiyana. Polypropylene imakonzedwa ndi kutenthetsa ma propylene monomers ku kutentha kwambiri ndikuwonjezera ku chothandizira ku polymerization, pomwe ulusi wa polyester umasinthidwa kukhala zinthu za fiber powonjezera ma cellulose etherification agents ndi zosungunulira ku polyester resin.

2. Makhalidwe a katundu

1. Potengera zakuthupi:

Polypropylene ndi yopepuka komanso imakhala ndi mphamvu zambiri za ulusi, koma kukana kwake kuvala komanso kukana kutentha kwambiri ndizosauka. Ulusi wa polyester uli ndi mphamvu zolimba komanso zolimba, komanso kutentha ndi kukana kwa mankhwala, zomwe zimapangitsa moyo wautali wautumiki.

2. Pankhani ya mankhwala:

Polypropylene imakhala ndi mankhwala okhazikika, samawonongeka mosavuta ndi ma acid, alkalis, ndi zina zotero, ndipo ilibe zinthu zoopsa komanso zovulaza. Ulusi wa polyester uli ndi mphete ya benzene ndipo umakhala ndi kukana kwa dzimbiri.

3. Pankhani yokonda zachilengedwe:

Polypropylene ndi thermoplastic material yomwe siiwonongeka mosavuta komanso imawononga chilengedwe. Ulusi wa polyester ukhoza kuwonongedwa ndi tizilombo toyambitsa matenda ndipo sudzawononga chilengedwe.

Kusiyana pakati pa PP sanali nsalu nsalu ndiPET nsalu yopanda nsalu

1. Zida za PP ndizotsika mtengo, pomwe zida za PET ndizokwera mtengo. Zinyalala za PP zitha kubwezeretsedwanso mu ng'anjo, pomwe zinyalala za PET sizingabwezeretsedwenso, motero mtengo wa PP ndi wotsika pang'ono.

2. PP imakhala ndi kutentha kwakukulu kwa madigiri pafupifupi 200, pamene PET imakhala ndi kutentha kwa madigiri pafupifupi 290. PET imalimbana ndi kutentha kwambiri kuposa PP.

3. Kusindikiza kwa nsalu zopanda nsalu, kutentha kwa kutentha, PP m'lifupi mwake kumachepa kwambiri, PET imachepa kwambiri, imakhala ndi zotsatira zabwino, PET imapulumutsa zambiri ndikuwononga pang'ono.

4. Kuthamanga kwa mphamvu, kupanikizika, mphamvu yonyamula katundu, ndi kulemera komweko, PET imakhala ndi mphamvu yowonjezereka, kupanikizika, ndi kunyamula katundu kuposa PP. 65 magalamu a PET ndi ofanana ndi 80 magalamu a PP potengera kupsinjika, kupsinjika, komanso kunyamula katundu.

5. Kuchokera ku chilengedwe, PP imasakanizidwa ndi zinyalala za PP zobwezerezedwanso, ndipo tchipisi zonse za PET ndi zatsopano. PET ndiyokonda zachilengedwe komanso yaukhondo kuposa PP.
