Makhalidwe, Kugwiritsa Ntchito Kwakukulu ndi Njira Yopangira Ma Spunbonded Nonwovens

1. Mbali
Good kukana kutentha, otsika kutentha kukana (polypropylene angagwiritsidwe ntchito kwa nthawi yaitali pa 150 ℃ ndi poliyesitala angagwiritsidwe ntchito kwa nthawi yaitali pa 260 ℃), kukana kukalamba, kukana ultraviolet, elongation mkulu, bata wabwino ndi permeability mpweya. , kukana dzimbiri, kutsekereza mawu, kupewa njenjete komanso kusavulaza.
Chachiwiri: Zida zazikulu za nsalu zosalukidwa zosalukidwa ndi polyester ndi polypropylene.
Zopangira zazikulu za nsalu zosalukidwa zosalukidwa ndi polypropylene ndi polyester (ulusi wautali ndi ulusi waufupi) nsalu zosalukidwa.Zomwe zimagwiritsidwa ntchito kwambiri komanso zomwe zimagwiritsidwa ntchito nthawi zambiri ndi zikwama zopanda nsalu, zonyamula zopanda nsalu, ndi zina zotero. N'zosavuta kuzindikira ma spunbonded nonwovens, ndipo nthawi zambiri kufulumira kwa njira ziwiri ndikwabwino.Nthawi zambiri, ma spunbonded nonwovens amapindika ndi rhombic.
Pa mlingo wogwiritsira ntchito, ukhoza kugwiritsidwanso ntchito ngati nsalu yonyamula maluwa, nsalu zonyamula katundu, ndi zina zotero, ndi makhalidwe ake a kukana kuvala, kumverera kolimba m'manja ndi zina zotero zimapanga chisankho chabwino kwambiri chopangira zinthu zoterezi.

Chachitatu, njira zamakono za spunbonded sanali nsalu nsalu
Polypropylene: polima (polypropylene+recycled material) -kutentha kwapamwamba kusungunula pampu yayikulu-sefa-metering pampu (kutumiza kochulukira) -kuzungulira (kutambasula mmwamba ndi pansi ndi kuyamwa polowera) ndi kukanikiza pansi zogudubuza (pre-reinforcement) -kugudubuza kotentha (kulimbitsa) ndi kudula mphero-yozungulira-reverse nsalu.
