Hauv kev lag luam niaj hnub, hlau microporous tshuab thiab cov khoom siv dav siv hauv ntau qhov chaw. Ntawm lawv, cov khoom siv textile (cov khaub ncaws thiab cov khoom siv hauv tsev) thiab cov khoom siv tiv thaiv kev kho mob suav rau feem ntau. Los ntawm cov khoom siv raw (tshuaj lom neeg) mus rau cov khoom tiav, cov khoom siv raw yuav tsum tau mus los ntawm ntau yam txheej txheem, xws li spinning, weaving, dyeing, sewing, thiab lwm yam. mus rau tshuaj fibers, yog li spinneret technology tau los ua.

Spinneret tseem hu ua spinnerette. nws yog ib yam khoom uas muaj ntau qhov me me hauv lub thimble zoo li hlau nozzle siv rau cov tshuaj fiber ntau spinning. Cov khoom raug melted los yog chemically yaj, ces yog nias tawm ntawm lub qhov los tsim filament, uas yog solidified los ntawm condensation, evaporation los yog txias. Spinnerets feem ntau yog ua los ntawm stainless hlau, tab sis rayon ntau lawm yuav tsum platinum. Qhov luaj li cas thiab cov duab ntawm lub qhov spinneret txiav txim siab lub filament's cross-sectional shape. Txhua lub qhov tsim ib qho filament, thiab cov filaments sib xyaw ua cov xov paj.

Nrog rau txoj kev loj hlob ntawm covid-19 nyob rau hauv lub ntiaj teb no, raws li zoo raws li qhov tshwm sim nyob rau hauv lub tebchaws United States thiab cov teb chaws Europe, cov khoom tiv thaiv nrog cov tub ntxhais technology ntawm nonwoven fabric (spun bonded fabric / melt blown fabric) tau txais lub ntiaj teb no cov kev xav dua. Los ntawm kev tsis sib haum xeeb nyob rau theem pib ntawm kev sib kis mus rau cov kev xav tau zoo tshiab, peb lub tuam txhab tau tsimyaj yajspinnerets&spun bonded spinneret&spinneret tuag header&non-woven npuag ntau lawm kabkom tau raws li kev xav tau ntawm kev lag luam, thiab tau txais cov lus pom zoo los ntawm kev ua lag luam.

Tsis tas li ntawd, peb lub tuam txhab tseem muaj kev lag luam loj ntawm spinnerets siv hauv cov tsoos weaving fabrics, xws li ntau yam sib xyaw spinnerets (hiav txwv-kob hom/sheath-corehom/ ntu-piehom), thiab raug xa tawm mus rau South Asia.
