Spunbond polypropylene jira

Oue spunbond nonwoven fabric imhando yemachira asina kuruka akagadzirwa kubva kuthermoplastic polypropylene (PP) fibers anosunganidzwa pamwechete nekupisa. Maitiro acho anosanganisira kuburitsa maPP fibers, ayo anobva arukwa uye akaiswa pasi nenzira isina kujairika kugadzira webhu. Dandemutande rinobva rabatanidzwa pamwechete kuita jira rakasimba uye rinogara.

Hunhu hwePP spun bond isiri yakarukwa jira

Polypropylene spunbond non-woven fabric ine maitiro ekureruka, kufema, kusimba, kudzivirira mvura, anti-static, uye kuchengetedza kwezvakatipoteredza.Polypropylene spunbond non-woven fabric chinhu chakareruka chine huremu huremu uye simba rekutakura mutoro wakasimba. Izvi zvinoita kuti ive yakanakira zvimwe zvinhu, inokodzera minda yakawanda yakadai sehutano, zvigadzirwa zvemumba, nezvimwe. Zvichakadaro, nekuda kwekureruka kwayo, zvakare zviri nyore kutakura nekuisa.

pp spunbond isiri yakarukwa machira anoshandisa

PP spunbond nonwoven jira rine zvakasiyana-siyana zvekushandisa pakurima, kuvaka, kurongedza, geotextiles, mota, midziyo yemumba. Spunbonded nonwoven fabric chigadzirwa chine mukana wekusimudzira, chinoshandisa zvakazara zvakanakira mafiber sezvinhu zvehutano. Icho chigadzirwa cheiyo indasitiri inosimukira chirango chakaumbwa nekubatanidzwa uye kupindirana kweakawanda dzidziso uye matekinoroji. Izvi zvinosanganisira magauni ekuvhiya, zvipfeko zvekudzivirira, mabhegi ekuuraya utachiona, masiki, manapukeni, machira emumba, machira ekupukuta, matauro ekumeso akanyorova, matauro emashiripiti, zvinyoro zvinyoro, zvigadzirwa zverunako, masanitary pads, uye machira ehutsanana anoraswa.

Kunzwisisa iyo spin bonding process

Unyanzvi hwekuruka, hunoshandiswa kugadzira machira asina kurukwa, hunosanganisira extruding thermoplastic polymers, kazhinji polypropylene (PP), kuita filaments inoenderera. Mushure maizvozvi, mafilaments anorongwa kuva chimiro chewebhu uye akabatanidzwa pamwechete kuti aite jira rakasimba, rinogara kwenguva refu. Mazhinji anodiwa maficha, akadai sesimba rakakura, kufema, kuramba mvura, uye makemikari kuramba, aripo mune inoguma PP spunbond nonwoven jira. Iyi ndiyo tsananguro yakadzama yeiyo spunbonding maitiro:

1. Extrusion yemapolymers: Kuwedzera kwepolymer kuburikidza ne spinneret, kazhinji muchimiro chepellets, ndiyo nhanho yekutanga mukuita. Iyo polima yakanyungudutswa inofambiswa pasi pekumanikidzwa kuburikidza nemaburi madiki akawanda e spinneret.

2. Filament spinning: Iyo polymer yakatambanudzwa uye yakatonhodzwa sezvainobuda muspinneret kugadzira filaments inoenderera. Kazhinji, idzi filaments dzine dhayamita ye15-35 microns.

3. Magadzirirwo eWebhu: Kugadzira dandemutande, mafilaments anobva aunganidzwa nenzira isingaite pabhandi rekutakura rinofamba kana dhiramu. Huremu hwewebhu hunowanzo 15-150 g/m².

4. Kusungirirana: Kusunganidza mafilaments pamwechete, dandemutande rinozovhenekwa nekupisa, kudzvanywa, kana makemikari. Nzira dzakawanda, dzakadai sekubatanidza kupisa, kusungirirwa kwemakemikari, kana mechanical needling, inogona kushandiswa kuita izvi.

5. Kupedzisa: Mushure mekubatana, jira rinowanzoita calender kana kupiwa kupera kuti riwedzere maitiro ayo ekuita, sekudzivirira kwemvura, UV resistance.
