Dab tsi yog lub hauv paus ntsiab lus ntawm non-woven npuag hnab

Non-woven fabric yog ib hom non-woven npuag uas ncaj qha siv cov polymer chips, luv fibers, los yog filaments los tsim ib hom tshiab ntawm cov khoom fiber ntau nrog cov mos mos, breathable, thiab tiaj tus qauv los ntawm ntau yam fiber ntau mesh txoj kev thiab kev sib koom ua ke. Piv nrog rau cov hnab yas ib txwm siv, cov hnab tsis-woven npuag muaj qhov zoo hauv qab no: lawv tau txais txiaj ntsig zoo, ib puag ncig tus phooj ywg, siv tau, dav siv, thiab muaj txoj haujlwm tseem ceeb tshaj tawm. Haum rau ntau yam kev ua lag luam thiab kev nthuav tawm, nws yog qhov khoom plig tshaj tawm tshaj tawm zoo tshaj plaws rau cov lag luam thiab cov tsev kawm
Cov khoom siv raw ntawm cov hnab tsis-woven yog polypropylene, thaum cov khoom siv ntawm cov hnab yas yog polyethylene. Txawm hais tias cov npe ntawm ob yam khoom zoo sib xws, lawv cov qauv tshuaj sib txawv heev. Cov tshuaj molecular qauv ntawm polyethylene muaj zog ruaj khov thiab yog qhov nyuaj heev rau degrade, yog li nws yuav siv sij hawm 300 xyoo rau cov hnab yas kom decompose tag nrho; Cov qauv tshuaj ntawm polypropylene tsis muaj zog, thiab cov saw hlau molecular tuaj yeem tawg tau yooj yim, uas tuaj yeem txo qis thiab nkag mus rau lub voj voog ib puag ncig tom ntej hauv daim ntawv tsis muaj tshuaj lom. Ib lub hnab tsis-woven tuaj yeem decomposed tag nrho hauv 90 hnub.
Non-woven fabric yog ib yam khoom uas tsis xav tau cov txheej txheem spinning los ua cov ntaub tsis-woven, tseem hu ua non-woven fabric. Vim tias nws tsuas yog xav tau kev taw qhia lossis randomly txhawb textile luv fibers lossis filaments los tsim cov qauv fiber ntau, thiab tom qab ntawd siv cov khoom siv hluav taws xob, thermal nplaum, lossis cov txheej txheem tshuaj los txhawb nws. Feem ntau cov hnab tsis-woven yog ua los ntawm spunbonded non-woven npuag.
Cias muab, cov ntaub uas tsis yog-woven tsis yog tsim los ntawm interweaving thiab weaving yarn tom qab yarn, tab sis los ntawm kev sib txuas ncaj qha fibers ua ke los ntawm lub cev txoj kev. Yog li ntawd, thaum koj tau txais cov nplaum hnyav hauv koj cov khaub ncaws, koj yuav pom tias nws tsis tuaj yeem rub tawm xov tom qab xov. Non-woven fabrics tawg los ntawm tsoos textile cov ntsiab lus thiab muaj cov yam ntxwv ntawm cov txheej txheem luv luv, ceev ceev ceev, siab yield, tsis tshua muaj nqi, dav siv, thiab ntau qhov chaw ntawm raw khoom.
Laminated non-woven npuag hnab, cov khoom siv txoj kev casting, thiab cov khoom sib xyaw yog ruaj. Thaum lub sij hawm cov txheej txheem sib xyaw, nws tsis lo, muaj qhov muag muag, tsis muaj kev xav ntawm yas, thiab tsis muaj tawv nqaij khaus. Nws yog qhov tsim nyog rau kev tsim cov ntaub ntawv kho mob pov tseg, cov ntaub pua tsev, cov ris tsho phais, kev sib cais, cov khaub ncaws tiv thaiv, khau npog, thiab lwm yam khoom tiv thaiv kev noj qab haus huv; Hom ntaub hnab no hu ua laminated non-woven fabric bag.
