Cov Ntaub Nonwoven: Ua Tsis Muaj Ib Txoj Xov

Dab tsi Is "Cov ntaub tsis yog ntaub" ?

Yog tias koj tau siv lub npog ntsej muag, daim ntaub so ntub, lossis lub hnab nqa khoom, koj tau kovcov ntaub tsis yog ntaub. Tiam sis ntawm no yog qhov tig: nws tsis muaj warp, tsis muaj weft, tsis muaj xov, thiab tsis muaj knitting. Cov ntaub ib txwm xav tau kev sib hloov thiab kev weaving - ob kauj ruam tseem ceeb. Nonwoven hla ob qho tib si. Cov fibers (lossis yas yaj) raug muab tso ncaj qha rau hauv lub vev xaib, tom qab ntawd sib txuas ua ke los ntawm cua sov, kev sib txhuam, lossis cov nplaum tshuaj. Xyoo 2022, Tuam Tshoj tsim tau 8.29 lab tons ntawm nws - ntau tshaj ib feem peb ntawm tag nrho thoob ntiaj teb. Nws yog lub lag luam loj hlob sai tshaj plaws hauv textiles, vim nws tsis txhawj txog "textiles" hlo li.

Meltblown: Lub Super-Filter

Meltblownpib nrog cov polypropylene pellets, uas tau yaj thiab extruded los ntawm cov nozzles me me. Blasts ntawm 200-300 ° C cua kub ncab cov yaj mus rau hauv microfibers tsuas yog 1-5 microns tuab - qee qhov zoo li 0.5 microns. (Ib tug tib neeg cov plaub hau yog li 70 microns.) Cov fibers ultra-fine no tsim ib lub maze ntom, tortuous uas ntes cov kab mob, droplets, thiab cov khoom me me. Yog vim li cas lub txheej nruab nrab ntawm lub ntsej muag phais yuav tsum tau meltblown. Lub ntes: nws khiav ntawm tsuas yog 1-5 m / min, zoo li tsis muaj zog, thiab tus nqi $ 3,500-5,500 ib tuj - ob mus rau peb zaug kim dua li lwm cov nonwovens. Yog li koj yeej tsis pom nws ib leeg; nws ib txwm yog tus phab ej zais cia ntawm cov khaubncaws sab nraud povtseg muaj zog dua.

Spunbond: Tus Neeg Ua Haujlwm

Spunbond kuj yaj cov polymer, tab sis nws extrudes cov filaments txuas ntxiv mus txog 15-35 microns tuab - coarser thiab muaj zog dua. Cua-ncab thiab muab tso rau ntawm txoj siv sia, lub web yog thermally bonded los ntawm cov menyuam kub. Qhov tshwm sim: tawv, tear-resistant ntaub uas khiav ntawm 50-500 m / feeb (txog li 1,000 m / feeb ntawm cov kab ceev ceev) - 100 npaug sai dua li meltblown. Qhov kev ceev ntawd slashes raug nqi rau $ 1,700-2,800 ib tuj. Spunbond yog koj lub hnab nqa khoom noj khoom haus, lub npog ua liaj ua teb, rooj tog zaum, thiab txheej sab nraud ntawm cov khaub ncaws tiv thaiv. Nws pheej yig thiab ruaj khov, tab sis tawv thiab yas - tsis yog ib yam dab tsi koj xav so koj lub ntsej muag nrog.

SMS: Ua ke zoo dua

Cov khoom siv tiag tiag tsis tshua xaiv ib txoj kev xwb. Cov qauv SMS-spunbond/meltblown/spunbond-muab ob qho zoo tshaj plaws ua ke. Cov khaub ncaws kho mob siv cov spunbond sab nraud los thaiv cov kua, nruab nrab meltblown los ntes cov khoom me me, thiab sab hauv spunbond rau kev nplij siab. Adaim npog phaiszoo ib yam: txheej sab nraud tiv thaiv cov dej txaws, cov ntaub meltblown ntes cov kab mob, thiab txheej sab hauv nqus cov dej noo. Txawm tias ntau daim ntaub so ntub kuj tseem ua ke txheej spunlace mos mos nrog lub hauv paus spunbond muaj zog. Cov txheej txheem ib leeg muaj qhov tsis zoo; kev sib xyaw ua ke ntse ua rau muaj kev ua tau zoo yam tsis muaj nqi ntau.

Tsis yog txhua yam Nonwovens yog tsim sib npaug

Cov ntaub tsis yog ntaubMuaj nyob txhua qhov chaw - daim npog ntsej muag, daim ntaub so tes, hnab, lim dej, thiab khaub ncaws - tab sis feem ntau cov neeg tsis paub qhov txawv ntawm meltblown thiab spunbond. Tam sim no koj paub lawm: xav tau lim dej? Mus meltblown. Xav tau lub zog thiab tus nqi qis? Spunbond yog koj cov lus teb. Thiab yog tias koj pom SMS, koj tab tom saib ib lub sandwich uas tau tsim zoo. Lub npe "ntaub" tib yam, kev ua tau zoo sib txawv heev - thiab qhov sib txawv ntawm tus nqi tsib npaug. Kev nkag siab txog cov kev no yuav tsis ua rau koj yog tus kws tshaj lij textile, tab sis nws yuav ua rau koj yog tus neeg yuav khoom ntse dua.
