chii chinonzi spunbond material

Kune marudzi mazhinji emachira asina kuruka, uye spunbond isiri-yakarukwa jira ndeimwe yacho. Zvinhu zvikuru zve spunbond jira risiri rakarukwa ipolyester uye polypropylene, ine simba rakakura uye yakanaka-yepamusoro-tembiricha kuramba. Pazasi, iyo isiri-yakarukwa machira kuratidzwa ichakuzivisa kwauri chii chinonzi spunbond jira risiri rakarukwa? chii chinonzi spunbond material? Ngatitarisei pamwe chete.

Chiispunbond nzira

Chikonzero chakakosha chekukura kwayo nekukurumidza ndechekuti inoshandisa ma polymers ekugadzira semidziyo. Iyi nzira inoshandisa musimboti wekemikari faibha kutenderera kuti irambe ichiita filament panguva yepolymer spinning process, iyo inozopfapfaidzwa muwebhu uye yakabatanidzwa zvakananga kugadzira machira asiri akarukwa. Nzira yekugadzira iri nyore uye inokurumidza. Kana ichienzaniswa neyakaoma isina-yakarukwa yekugadzira machira tekinoroji, inobvisa akatevedzana anonetesa epakati maitiro akadai sefiber curling, kucheka, kurongedza, kufambisa, kusanganisa, uye kusanganisa Mhedzisiro yakakosha yekugadzirwa kwemazhinji kuita kuti zvigadzirwa zve spunbond zvive nesimba rakawanda, mutengo wakaderera, uye yakagadzikana mhando. Kutambanudzwa kwenzira ye spunbond ndiro dambudziko rekutanga rehunyanzvi rekuwana mafine denier faibha uye akasimba-akasimba asina kuruka zvinhu, uye parizvino nzira huru ndeyekuyerera kwemhepo kutambanudza tekinoroji. Kuti tienderere mberi nekuvandudza kufambiswa kwemhepo kwespunbond fibers, kukwirira kwepamusoro kwegomba rimwe chete kuruka, dhizaini yemaburi e-high-density spinneret, uye maitiro adzo pakugadzirwa uye kunaka kwezvinhu zvisina kurukwa, tiri kudzidza magadzirirwo egwara redhizaini rinobatanidza kudzvanya kwakanaka uye kudzvanywa kwakashata, pamwe nekukanganisa kwe electrostatic kutenderera pakutenderera kwewebhu, yunifomu faibha, upamhi hwewebhu. Iyi imhando yakakosha yemidziyo ye spunbond yakagadzirirwa maindasitiri, Rimwe remabasa akakosha emhando mbiri-zvikamu zve spunbond michina.

chii chinonzi spunbond material

The raw materials forspunbond machira asina kurukakunyanya zvinosanganisira cellulose fibers uye synthetic fibers, iyo inogadzirwa kuburikidza neiyo spunbond process. Iine kunzwa kwakanaka kwemaoko, kufema, uye kupfeka kuramba, uye inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana. Maitiro ekugadzira spunbond asiri akarukwa machira ari nyore, anodhura, uye ane tarisiro yemusika wakakura. Zvinotarisirwa kuti kuchave nekumwe hunyanzvi uye budiriro mune ramangwana, kuitira kuti spunbond isina-yakarukwa jira rinogona kuita basa rakakura muminda dzakasiyana.

Cellulose fiber

Cellulose fiber ndechimwe chezvinhu zvakakosha zvekugadzira machira e spunbond asiri akarukwa. Cellulose ndeye yakasikwa organic musanganiswa inowanikwa zvakanyanya muchirimwa maseru madziro. Mafayibha mazhinji ezvirimwa, akadai sedonje, rineni, hemp, nezvimwe, ane akawanda cellulose. Zvidyarwa izvi zvinosangana nehurongwa hwekugadziriswa, sekupepeta, kubvisa mafuta, uye kufashaidza, kubvisa cellulose kubva muzvirimwa. Zvino, kuburikidza nemaitiro e spunbond, shinda dze cellulose dzinotambanudzwa uye dzakanangidzirwa kuita jira re spunbond risiri rakarukwa. Machira ecellulose ane kupfava kwakanaka uye kufema, achiita machira e spunbond asiri akarukwa ave nekunzwa kweruoko kwakanaka uye kufema.

Synthetic fibers

Synthetic fibers ndechimwe chinowanzo shandiswa mbishi machira e spunbond asiri akarukwa. Synthetic fibers mafibhi akaitwa neartificial synthesis kana makemikari ekugadzirisa, akadai sepolyester fibers, nylon fibers, etc. Synthetic fibers ine unhu hwakanaka hwemuviri uye kugadzikana kwemakemikari, uye maitiro emagetsi anogona kugadziriswa sezvinodiwa. Mukugadzira machira eSpunbond asiri akarukwa, machira ekugadzira anowanzo kusanganiswa neselulosi fiber kuvandudza kusimba uye kupfeka kuramba kwemachira e spunbond asiri akarukwa.

Chii chinonzi spunbond jira risiri rakarukwa?

Machira akarukwa asina kurukwa, anonyanya kugadzirwa nepolyester uye polypropylene, ane simba repamusoro uye akanaka-yepamusoro-tembiricha kuramba. Jira rakarukwa risiri rakarukwa rinoburitsa uye rinotambanudza mapolima kuti aite mafilamendi anoenderera, ayo anobva aiswa muwebhu. Dandemutande rinobva razvisungirira, rinosungwa nemafuta, rakasungwa nekemikari, kana kusimbiswa nemuchina kuti rishanduke kuita jira risiri rakarukwa.

Kusarudzwa kwezvinhu zvakasvibiswa

Izvo zvigadzirwa zvinoshandiswa mumutsara wekugadzira zvine chekuita nekumisikidzwa kwemusika uye chinangwa chechigadzirwa. Paunenge uchigadzira zvigadzirwa zvemusika wakaderera, nekuda kwezvinodikanwa zvakaderera zvezvigadzirwa, kuti uderedze mutengo wekugadzira, yakaderera mhando zvigadzirwa zvinogona kusarudzwa. Zvakapesana ndezvechokwadiwo.

Mazhinji spunbond nonwoven ekugadzira mitsetse anoshandisa granular polypropylene (PP) machipisi seyakagadzirwa, asi kune zvakare akati wandei madiki ekugadzira mitsara anoshandisa hupfu PP zvinhu mbishi, uye mimwe mitsetse yekugadzira inoshandisa recycled polypropylene raw materials. Pamusoro pezvigadzirwa zvegranular, mitsara yekugadzira yakanyungudutswa inogona zvakare kushandisa spherical mbishi zvinhu.

Mutengo wekucheka wakanangana nehukuru hweMFI kukosha kwayo, kazhinji iyo yakakura kukosha kweMFl, iyo inokwira mutengo. Naizvozvo, zvinofanirwa kunyatso tarisa maitiro ekugadzira, maitiro emidziyo, mashandisirwo echigadzirwa, mutengo wekutengesa chigadzirwa, mutengo wekugadzira, uye zvimwe zvinhu zvekusarudza zvigadzirwa zvichashandiswa.
