Txij li thaum nees nkaum-thawj Xyoo, kev loj hlob ntawm yaj cua tshuab nonwovens nyob hauv lub ntiaj teb tab tom loj hlob.
Roob lub tuam txhab thiab Nordson lub tuam txhab tau tsim lub tshuab tivthaiv dual kua tshuab ua ntej, nrog rau cov tawv nqaij, cov duab sib luag, daim duab peb sab thiab lwm yam. Feem ntau qhov loj me me yog nyob ze rau ntawm 2. Tus nab npawb ntawm qhov hauv lub xos tshuaj tiv thaiv tuaj yeem ncav cuag 100 qhov ntawm ib nti, thiab qhov ntau ntau ntawm txhua lub qhov mus txog 0.5g / ntsiab lus.
Tawv plaub hom: nws tuaj yeem ua rau cov ntaub qhwv tsis tau zoo thiab muag rau hauv concentric, eccentric thiab heteromorphic cov khoom. Feem ntau pheej yig cov khoom ua rau cov tub ntxhais kawm ntawv tseem ceeb, qhov tshwj xeeb, lossis tshwj xeeb tshaj ntawm cov polymer xws li txheej tawv txheej, xws li cov tub ntxhais ntawm cov tshuaj polypropylene, cov tawv nqaij yog nylon los ua fiber ntau hygroscopic, qhov tseem ceeb yog polypropylene, muaj pes tsawg melting point polyethylene los yog hloov polypropylene, hloov polyester, thiab lwm yam. Rau carbon carbon conductive fibers, tus tub ntxhais txawj coj qhwv hauv nws.
Qhov sib txuam tsis zoo: nws yuav ua rau tsis-woven npuag nrog zoo elasticity, feem ntau yog ua los ntawm ob hom polymers, los yog txawv viscosity ntawm tib hom polymer ua los ntawm parallel ob chav fibers, siv txawv thermal shrinkage ntawm txawv polymers yuav ua rau kauv curl fiber. Piv txwv, 3M tau tsim cov nonwovens rau cov kua tshuab ntshiab / PP ob qho tib si, uas ua rau cov khoom tsis zoo zoo vim tias qhov txawv txav thiab khawm caws.
