Spunbond:
Cov filaments txuas ntxiv ntawm cov kab sib luag sib luag.
High tensile lub zog (Astm D5034: 25-120 N / 5CM).
Smooth surface–good for liquid repellency (AATCC 22 rating >4).
Meltblown:
Cov microfiber nrog kev ua tsis taus, muaj kev sib nkag siab.
Tsawg lub zog nrog thaj chaw siab (10-100 zaug spunbond).
Kev them nqi hluav taws xob txhim kho cov palgle paltration (piv txwv li, 95% + rau pm 0. 3).
Kev Kawm Kev Kawm: Ib lub tuam txhab kev kho mob spunbond (sab nraud) nrog meltblown (nruab nrab) hauv qib 3 tus nqi phais, uas khaws cov khoom siv SMS.
