Koj puas paub cov laj thawj vim li cas cov ntaub tsis-woven siv hauv kev kho mob?

Nonwovens tau siv nyob rau hauv kev kho mob kev lag luam txij thaum Ntiaj Teb Tsov Rog II, thaum muaj ntau yam khoom kho mob tshiab xav tau. Nonwovens tau suav tias yog cov khoom siv kab mob zoo tshaj plaws hauv ntau cov ntawv tshaj tawm. Nws kuj tau pom tias lawv txo cov pa paug hauv huab cua zoo dua li flax. Nonwovens tau dhau los ua kev loj hlob zoo heev, thiab niaj hnub no lawv ua tau zoo tshaj lawv cov khoom siv hauv ntau qhov chaw, suav nrog nqi, kev ua tau zoo, thiab kev pov tseg. Hauv tsev kho mob, kev sib kis kab mob sib kis tsis tu ncua yog ib qho teeb meem tseem ceeb. Qhov laj thawj tseem ceeb ntawm qhov no yog kev siv lub ntsej muag lub ntsej muag, lub tsho ntev, thiab lwm yam khoom zoo sib xws, uas tuaj yeem kis tau kab mob thiab kis kab mob. Kev taw qhia ntawm nonwovens tau pab hauv kev tsim cov khoom pheej yig dua, cov khoom siv pov tseg.

Vim li cas ho mus rau lub npog ntsej muag tsis muaj woven? Hauv tsev kho mob, lub qhov ncauj qhov ntswg phais uas tsis yog-woven yog ib qho tseem ceeb ceev faj txog kev nyab xeeb rau cov neeg mob thiab cov neeg ua haujlwm kho mob. Lub qhov ncauj qhov ntswg zoo yog qhov tseem ceeb rau cov thawj coj hauv tsev thiab cov neeg saib xyuas kev yuav khoom siv kev nyab xeeb yooj yim no. Cov ntaub ntawv siv nyob rau hauv cov qhov ncauj qhov ntswg yuav tsum txwv tsis pub cov kab mob los ntawm kev tsiv teb tsaws ntawm tus kws phais lub qhov ncauj mus rau cov neeg mob lub qhov ncauj thiab vice versa vim lub minuscule loj ntawm cov kab mob. Tsis tas li ntawd, lub npog ntsej muag yuav tsum tau tiv thaiv tus neeg siv los ntawm cov molecules loj dua nyob rau hauv qhov chaw phais, xws li splattering ntshav. Txawm li cas los xij, dab tsi ua rau hom daim npog qhov ncauj qhov ntswg zoo dua rau cov ntaub npog ntsej muag uas siv tau rau cov kws kho mob?

Xya tus yam ntxwv ntawm cov tsoos microporous textiles tau muab piv nrog cov ntawv xov xwm nonwoven hauv ib txoj kev tshawb fawb luam tawm nyob rau hauv Phau ntawv Journal of Academia thiab Industrial Research: mechanical resistance, linting, bacterial permeability, liquid permeability, flexibility, drapeability, and comfort. Cov ntaub tsis-woven ua tau zoo dua li lwm cov ntaub hauv plaub ntawm xya pawg, thiab lawv muaj kev sib tw hauv ob ntawm peb. Dab tsi ntxiv qhov zoo dua yog tsim lub npog ntsej muag uas tsis yog-woven?

1. Lawv yog cov tseem ceeb rau lub neej txhua hnub.

Hauv Tebchaws Meskas ib leeg, muaj 5,686 lub tsev kho mob tau lees paub uas muaj ze li ib lab txaj. Qhov no yog tus lej staggering thaum koj xav txog cov khoom siv pov tseg uas tsis yog khoom siv. Lub npog ntsej muag phais yog ib qho tseem ceeb ntawm kev saib xyuas. Tau ntau xyoo, cov qhov ncauj qhov ntswg zoo tsim los ntawm cov khoom siv nrog cov khoom zoo tshaj plaws tuaj yeem raug muag raws li cov khoom lag luam.

2. Lawv yog cov zoo tshaj rau woven fabrics nyob rau hauv ntau txoj kev.

Lawv muaj peev xwm ua kom pom cov kab mob ntau dua, nce cov cua ntws, thiab txo cov nqi tsim khoom ntxiv rau cov yam ntxwv yav dhau los.

3. Lawv siv tau rau cov neeg ua haujlwm hauv tsev kho mob.

Tom qab siv, cov npog ntsej muag uas tsis yog-woven pov tseg tau ntim, kom tsis muaj menyuam, thiab muab pov tseg tam sim ntawd. Cov ntaub ntawv siv tsis tas yuav khaws cia, thiab cov neeg ua haujlwm hauv tsev kho mob yuav tsum tau ntxuav, ua kom tsis muaj menyuam, thiab ntim lawv rau kev siv yav tom ntej. Cov khoom siv dab tsi mus rau hauv kev ua lub npog ntsej muag uas tsis yog-woven? Muaj ob hom fibers siv nyob rau hauv non-woven surgical masks: hluavtaws thiab ntuj fibers. Lub ntuj fibers uas siv yog rayon, paj rwb, thiab ntoo pulp. Cov txiaj ntsig ntawm ntoo pulp suav nrog nws tus nqi qis, ntim me me, thiab nqus dej muaj zog. Cov kab mob tuaj yeem hnav ncaj qha nrog paj rwb lossis rayon. Lawv yog cov zoo tshaj nonwovens nrog zoo nqus dej.

Kev ua pa zoo heev, kev ruaj ntseg zoo, kev ua haujlwm siab, kev ua haujlwm siab, kev ua haujlwm zoo, kev ua kom sov zoo, muaj peev xwm tuav tau dej zoo, thiab cov fibers uas tsis yog-allergenic thiab tsis khaus yog qee qhov laj thawj vim li cas cov fibers ntuj tsim cov qhov ncauj qhov ntswg pov tseg zoo heev hauv kev lag luam kho mob. Feem ntau siv hluavtaws fibers hauv daim ntawv thov no yog polyester thaum lub zog siab, yooj yim ntawm kev ua kom tsis muaj menyuam, thiab cov khoom siv tshuab yog qhov tseem ceeb; bicomponent fibers, uas yog dav siv rau thermal bonding thiab txhim kho functionality; thiab polypropylene, uas muaj cov khoom zoo rheological, hydrophobicity, thiab tus nqi qis. Nrog rau ntau lwm yam zoo, cov khoom siv hluavtaws xav txog cov khoom muaj zog, hnyav ua haujlwm, static dissipation, thiab lwm yam. Lub npog ntsej muag tsis-woven yuav tsum muaj cov khoom siv hluavtaws nrog cov khoom nram qab no: hydrophobicity, affordability, siab zog, tsawg ntom, thiab pov tseg zoo. Cov txheej txheem dab tsi koom nrog hauv kev tsim khoom?

Lawv muaj stability nyob rau hauv qhov ntev thiab yog mos thiab ntxeem tau. Tsis tas li ntawd, spunbonding feem ntau yog siv rau hauv cov khoom xws li cov khaub ncaws pov tseg, headgear, khau npog, lub ntsej muag lub ntsej muag, thiab cov ntawv txheeb. Cov yam ntxwv ntawm lub vev xaib sib txawv tuaj yeem ua tiav los ntawm kev siv cov txheej txheem sib txawv xws li kev ua kom qhuav, tso dej ntub, thiab daim npav, nyob ntawm seb yam xws li qhov xav tau ntawm lub vev xaib thickness thiab cov cuab yeej sib txuas ceev. Carding tuaj yeem siv los tsim cov webs sib sib zog nqus rau cov khoom siv tu cev thiab kev siv tshuab. Carding generates ceev heev, zoo webs. Muaj ntau txoj hauv kev los ua kom tiav kev sib raug zoo, ib qho ntawm cov thermal bonding ntawm hluavtaws fibers thiab lawv cov blends. Cov cuab yeej sib txuas uas nthuav dav nrawm tshaj plaws yog hydroentangling. Hauv daim npog qhov ncauj pov tseg, nws tau siv tshwj xeeb. Nws zoo li textile thiab zoo meej rau cov khoom xws li ntaub qhwv, hnav khaub ncaws, tsev kho mob khaub ncaws, thiab lwm yam.

Piv nrog rau cov hluavtaws fibers, qhov kawg pov tseg daim npog qhov ncauj yog kim kim txawm tias nws muaj superior zoo. Txhawm rau txhim kho nws cov purity thiab, yog li ntawd, nws qhov kev lees paub hauv kev kho mob thiab kev noj qab haus huv, paj rwb feem ntau yog mercerized thiab bleached. Paj rwb cov ntsiab lus siab plua plav ua rau nws nyuaj thiab. Tsis tas li ntawd, cov ris tsho phais, paj rwb swabs, curtains, gauze, pov tseg cov khaub ncaws, ntaub qhwv, ntaub qhwv qhov txhab, thiab lwm yam khoom uas tsis yog-woven yog cov zoo tshaj plaws siv rau ntuj fibers. Hauv kev ua cov paj rwb, kev sib koom ua ke zoo li hydroentanglement rau cov khoom nqus tau zoo, thermal bonding ntawm polyolefin thiab paj rwb, thiab resin bonding (rau substrates) yuav siv tau.Technology ntawm hluavtaws fibers: Synthetic fibers feem ntau blended nrog rayon los yog paj rwb. Txhua txoj kev sib khi tsim nyog tuaj yeem siv los ua kom lawv sib txuas. Meltblown hluavtaws fibers yog lwm qhov kev xaiv. Meltblown fiber webs yog qhov nyiam rau cov ntawv thov xws li lub ntsej muag phais tsis-woven vim lawv txoj kab uas hla me me thiab pom kev ua haujlwm siab. Txhua txoj kev tuaj yeem ua tau zoo ntawm cov hluavtaws fibers, tab sis nws feem ntau yog nyob ntawm seb lawv yuav siv li cas thaum kawg.

Tom qab ua tiav: Kev kho mob nonwovens yuav tsum tau muab qhov ua tiav tsim nyog rau kev siv. Lub npog ntsej muag uas tsis yog-woven tuaj yeem muaj ntau yam khoom ua tiav, xws li cov tshuaj tua dej, tshuaj ntxuav tes, nplaim hluav taws, tshuaj tua kab mob, thiab cov av tso tawm. Hauv kev xaus, cov khoom tsis-woven tau tag nrho cov khoom lag luam textile kev kho mob niaj hnub no. Non-woven fabrics 'extract qualities thiab yooj yim ntawm kev hloov kho tau ua rau lawv indispensable nyob rau hauv no kev lag luam. Vim muaj kev loj hlob sai ntawm nroog loj thiab qhov tshwm sim ntawm cov tub ntxhais hluas, cov neeg paub txog kev noj qab haus huv, qhov kev thov rau kev kho mob nonwovens tau nce ntau hauv cov teb chaws hauv Asia, Africa, thiab South America. Nws tau cia siab tias cov nonwovens yuav txuas ntxiv mus rau qhov kev thov siab hauv kev lag luam kho mob.
