Keeb kwm thiab kev loj hlob ntawm koob punched non-woven fabrics

Koob punched non-woven ntaub

Koob punched non-woven npuag yog ib yam ntawm cov txheej txheem qhuav tsis-woven npuag, uas muaj xws li loosening, combing, thiab nteg luv fibers rau hauv ib lub fiber mesh. Tom qab ntawd, fiber ntau mesh yog ntxiv rau hauv cov ntaub los ntawm ib rab koob. Lub koob muaj ib tug nuv, uas pheej punctures lub fiber mesh thiab ntxiv dag zog rau nws nrog tus nuv, tsim ib rab koob punched non-woven npuag. Cov ntaub tsis woven tsis muaj qhov sib txawv ntawm warp thiab weft kab, thiab cov fibers hauv cov ntaub yog nkig, nrog me ntsis txawv ntawm warp thiab weft kev ua tau zoo.

Cov txheej txheem ntau lawm rau koob punched non-woven fabrics yog tshuaj ntsuam luam ntawv. Qee qhov ntawm lub vijtsam luam ntawv phaj tuaj yeem dhau los ntawm tus number case thiab xau mus rau lub substrate. Qhov seem ntawm qhov screen ntawm lub phaj luam ntawv raug thaiv thiab tsis tuaj yeem dhau los ntawm tus number case, ua ib qho khoob ntawm lub substrate. Nrog rau lub vijtsam txhob lo lo ntxhuav raws li kev txhawb nqa, lub vijtsam txhob lo lo ntxhuav yog nruj ntawm tus ncej, thiab tom qab ntawd photosensitive nplaum yog siv rau ntawm qhov screen los tsim cov duab thaij duab. Tom qab ntawd, cov duab zoo thiab tsis zoo hauv qab daim hlau yog glued mus rau cov ntaub tsis-woven rau lub hnub kom qhuav, thiab nthuav tawm. Txoj kev loj hlob: Cov khoom tsis yog tus cwj mem ntawm lub phaj luam ntawv raug rau lub teeb los ua ib zaj duab xis kho, uas khi lub mesh thiab tiv thaiv tus number case kis tau tus mob thaum luam ntawv. Lub mesh ntawm tus number case ntawm lub phaj luam ntawv tsis raug kaw, thiab tus number case dhau los ntawm lub sijhawm luam ntawv, tsim cov cim dub ntawm lub substrate.

Kev loj hlob ntawmkoob punched non-woven fabrics

Lub tswv yim ntawm koob punched non-woven npuag los ntawm Tebchaws Meskas. Raws li thaum ntxov xyoo 1942, Tebchaws Asmeskas tau tsim cov ntaub tshiab zoo li cov khoom lag luam uas txawv ntawm cov ntsiab lus textile, vim nws tsis yog tsim los ntawm kev sib tw los yog xaws, nws hu ua non-woven fabric. Lub tswv yim ntawm koob punched non-woven npuag tau txuas ntxiv mus rau hnub no thiab tau txais los ntawm cov teb chaws thoob ntiaj teb. Cia peb ua raws li tus editor kom paub txog keeb kwm thiab kev loj hlob ntawm rab koob punched non-woven fabrics.

Xyoo 1988, ntawm International Nonwoven Fabric Symposium uas muaj nyob rau hauv Shanghai, Mr. Massenaux, Secretary General ntawm European Nonwoven Fabric Association, txhais cov ntaub uas tsis yog woven raws li cov ntaub zoo li cov khoom siv los ntawm cov kev taw qhia lossis cov fiber ntau tsis zoo. Nws yog cov khoom siv fiber ntau ua los ntawm kev siv cov kev sib txhuam ntawm cov fibers, los yog nws tus kheej nplaum quab yuam, los yog lub zog nplaum ntawm cov nplaum sab nraud, los yog sib txuas ob lossis ntau lub zog, uas yog, los ntawm kev sib txhuam, kev sib txuas, los yog kev sib koom ua ke. Raws li cov ntsiab lus no, cov ntaub ntawv tsis-woven tsis suav nrog cov ntawv, cov ntaub npuag, thiab cov ntaub knitted. Lub ntsiab lus ntawm cov ntaub tsis-woven hauv Suav teb tus qauv GB / T5709-1997 "Terminology rau Textiles thiab Non-woven Fabrics" yog: taw qhia los yog randomly teem fibers, ntawv zoo li fabrics, fiber ntau webs los yog mats ua los ntawm kev sib txhuam, kev sib txuas, los yog ib tug ua ke ntawm cov txheej txheem, tsis suav cov ntawv, woven fabrics, tunings, knitted fabrics. yarns, thiab ntub shrink xav cov khoom. Cov fibers uas siv tau tuaj yeem yog cov fibers ntuj lossis tshuaj fibers, uas tuaj yeem ua cov fibers luv, ntev filaments, lossis fiber ntau zoo li cov khoom tsim ntawm qhov chaw. Cov ntsiab lus no qhia meej meej tias cov khoom tufted, cov khoom siv xov paj knitted, thiab cov khoom xav tau txawv ntawm cov khoom tsis-woven.

Yuav ua li cas ntxuav koob punched non-woven fabrics

Xaiv cov tshuaj ntxuav tes uas tsis muaj lub ntsej muag nrog lub ntsej muag zoo nkauj thiab tsis muaj tshuaj dawb rau kev ntxuav, ntxuav tes nyias, thiab tsis txhob siv lub tshuab ntxhua khaub ncaws kom tsis txhob ua rau lub ntsej muag puas.
Thaum tu rab koob punched non-woven fabrics, siv lub siab maj mam, thiab txawm tias qhov qias neeg tsuas yog yuav tsum tau maj mam rub. Tsis txhob siv txhuam los txhuam. Siv cov tshuaj zawv plaub hau thiab cov tshuaj pleev ib ce los ntxuav rab koob punched non-woven fabrics yuav txo tau qhov tshwm sim ntawm pilling. Tom qab ntxuav, dai nws nyob rau hauv ib qho chaw ventilated thiab cia nws qhuav lawm. Yog xav tau kom qhuav, thov siv qhov ziab kom qhuav.

Lub voj voog rwb thaiv tsev ntawmkoob punched nonwoven ntaub

Greenhouse growers tsis paub txog kev rwb thaiv tsev. Ntev npaum li huab cua txias, lawv yuav muab tso rau hauv. Piv nrog rau cov khoom siv rwb thaiv tsev ib txwm muaj, cov ntaub npog rwb thaiv tsev muaj qhov zoo ntawm cov hluav taws xob me me hloov coefficient, zoo rwb thaiv tsev, nruab nrab qhov hnyav, yooj yim dov, zoo cua tsis kam, dej tsis kam, thiab kev pab cuam lub neej txog li 10 xyoo.

1. Lub koob punched non-woven rwb thaiv tsev txheej muaj peb txheej, thiab koob punched non-woven rwb thaiv tsev npog yog ua los ntawm cov ntaub ntawv tsis-woven waterproof. Tsawg qhov cua tuaj yeem txo cov cua sov dissipation ntawm qhov kub thiab txias rau qee qhov, ua si qee lub luag haujlwm hauv kev rwb thaiv tsev ntawm thermal rwb thaiv tsev paj rwb quilt.

2. Lub koob punched non-woven npuag rwb thaiv tsev core yog lub ntsiab rwb thaiv tsev txheej. Cov nyhuv rwb thaiv tsev ntawm rab koob punched non-woven rwb thaiv tsev pam tsuas yog nyob ntawm qhov tuab ntawm cov tub ntxhais sab hauv. Lub rwb thaiv tsev tseem ceeb yog sib npaug rau ntawm txheej txheej txheej ntawm rwb thaiv tsev pam.

3. Qhov tseem ceeb hauv kev rwb thaiv tsev yog lub thickness ntawm cov tub ntxhais, lub thickness ntawm cov tub ntxhais, thiab qhov zoo ntawm rwb thaiv tsev nyhuv. Thaum siv cov ntaub ntawv rwb thaiv tsev hauv tsev cog khoom, cov ntaub thaiv npog tuab feem ntau yog xaiv. Lub thickness ntawm lub tsev xog paj rwb thaiv tsev tub ntxhais feem ntau yog 1-1.5 centimeters, thaum lub rwb thaiv tsev txheej thickness siv nyob rau hauv engineering yog 0.5-0.8. Xaiv cov ntaub ntawv rwb thaiv tsev nrog cov thicknesses sib txawv raws li kev siv sib txawv.

4. Koob punched non-woven npuag, ua cov khoom tseem ceeb rau tsev cog khoom rwb thaiv tsev quilts, muaj cov yam ntxwv ntawm siab tensile lub zog, tsis loosening, huab cua tsis kam, thiab tsis ntshai ntawm corrosion. Lub voj voog ntawm rab koob punched non-woven npuag tsev cog khoom rwb thaiv tsev quilts feem ntau yog 3-5 xyoos.

Lub hauv paus ntsiab lus ntawm kev xaiv fiber ntau ntau yam hauv kev tsim cov koob punched non-woven fabrics

Lub hauv paus ntsiab lus ntawm kev xaiv cov fibers yog qhov tseem ceeb thiab cov teeb meem nyuaj hauv kev tsim cov koob punched non-woven fabrics. Feem ntau, cov hauv qab no yuav tsum tau ua raws li thaum xaiv cov fibers.

1. Cov fibers xaiv rau koob punched non-woven npuag yuav tsum muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm cov khoom npaj siv.
Kev faib tawm thiab xaiv cov koob punched non-woven npuag fiber ntau raw cov ntaub ntawv.

2. Cov lus qhia tshwj xeeb thiab cov khoom ntawm rab koob punched non-woven npuag fibers yuav tsum tau yoog raws li kev ua tau zoo thiab cov yam ntxwv ntawm cov khoom siv ntau lawm. Piv txwv li, cov ntaub ntawv ntub dej feem ntau yuav tsum muaj fiber ntau ntev tsawg dua 25mm; Thiab combing rau hauv lub vev xaib feem ntau yuav tsum muaj fiber ntau ntev ntawm 20-150mm.

3. Raws li lub hauv paus ntsiab lus ntawm lub rooj sib tham saum toj no ob lub ntsiab lus, nws yog qhov zoo dua kom muaj tus nqi qis rau cov khoom siv fiber ntau. Vim tias tus nqi ntawm koob punched non-woven npuag feem ntau yog nyob ntawm tus nqi ntawm cov khoom siv fiber ntau. Piv txwv li, nylon muaj kev ua tau zoo ntawm txhua yam, tab sis nws tus nqi yog siab dua polyester thiab polypropylene, uas txwv nws daim ntawv thov hauv koob punched non-woven fabrics.
