Eritilgan non-woven fabric is called the "heart" of medical surgical mask and N95 mask in the industry. It is the filter layer in the middle of mask, with good filtration, shielding, heat insulation and oil absorption, and is an important raw material for mask production. It is necessary to use melt blown non-woven fabric to produce masks. The gap of mask is huge, so the gap of melt blown non-woven fabric will be bigger!
PP is the main raw material of melt blown cloth, and the fiber diameter can reach 1-5 μ M. There are many gaps, fluffy structure and good anti wrinkle ability. These ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt blown cloth has good filtration, shielding, heat insulation and oil absorption. It can be used in the fields of air, liquid filter material, isolation material, absorption material, mask material, heat preservation material, oil absorption material and wiping cloth.

Tibbiy jarrohlik niqoblari va N95 niqoblari odatda ko'p qatlamli tuzilmani qabul qiladi, bu qisqacha SMS tuzilmasi deb ataladi: bir qatlamli qatlam (lar) ichki va tashqi tomondan ikkala tomonda joylashgan; eritilgan puflangan qatlam (m) o'rtada bo'lib, u odatda bir qatlamli yoki ko'p{3}}qatlamga bo'linadi.
Samolyot niqobi odatda PP Spunbond plyus eritilgan buzadigan amallar va PP Spunbond yoki qisqa tolalar terining teginishini yaxshilash uchun bir qatlam uchun ishlatilishi mumkin. Uch oʻlchovli-chashka shaklidagi niqob odatda PET polyester igna paxta va eritilgan puflangan va igna paxta yoki PP Spunbonddan iborat. Ular orasida tashqi qatlam suv o'tkazmaydigan ishlovga ega bo'lgan to'qilmagan mato bo'lib, u asosan bemorlardan tomchilarni ajratish uchun ishlatiladi; o'rta qatlam niqoblar ishlab chiqarish uchun muhim xom ashyo bo'lgan, yaxshi filtrlash, ekranlash, issiqlik izolatsiyasi va yog'ni singdirish xususiyatiga ega bo'lgan maxsus ishlov berilgan-to'qilmagan mato; ichki qatlam umumiy-to'qilmagan mato.
Niqobning o'ralgan qatlami (lar) va eritilgan qatlam (m) to'qilmagan matoga tegishli bo'lsa-da-va xomashyo polipropilen bo'lsa-da, ishlab chiqarish jarayoni bir xil emas.
Ichki va tashqi tomonlarning har ikki tomonida o'ralgan tolalarning diametri taxminan 20 mikron; o'rtadagi eritilgan puflangan tolaning diametri faqat 2 mikron bo'lib, u yuqori erigan yog 'tolasi deb ataladigan polipropilen materialdan tayyorlanadi.
