Textile cov ntawv
Cov ntaub ntawv insulile yog cov khoom siv insulator, nrog cov tshuaj insulator insulator, tshwj xeeb tshaj yog cov khoom siv hluavtaws zoo li polyester, acrylic fiber ntau, thiab chloro fiber ntau. Yog li ntawd, nyob rau hauv cov txheej txheem ntawm textile ua, vim muaj kev sib chwv ze thiab sib txhuam ntawm fiber ntau thiab cov fiber ntau lossis siv lub tshuab fiber thiab siv lub tshuab. Nws ua rau hloov chaw ntawm cov hluav taws xob them rau saum npoo ntawm cov khoom, ua rau hluav taws xob zoo nkauj. Cov fibers nrog tib tus nqi rov qab sib txawv, thiab cov fibers nrog cov nqi sib txawv nyiam cov feem. Raws li qhov tshwm sim, tus swb yog plaub, cov yarn ham yog qhov nce, cov xov paj muaj zog yog nce, cov lus sib tw tau nce, thiab cov kab txaij dispersive yog tsim rau ntawm daim ntaub saum npoo. Tom qab cov khaub ncaws hnav hluav taws xob, muaj cov hmoov av ntau yuav nqus tau, uas yooj yim kom paug. Ntxiv mus, khaub ncaws thiab tib neeg lub cev, ris tsho hnav khaub ncaws thiab khaub ncaws yuav tsum tau entangled lossis tsim hluav taws xob hluav taws xob. Yog li no, elctrostatic cuam tshuam cuam tshuam kev ua kom du, qhov zoo ntawm cov khoom lag luam thiab hnav cov khoom ntawm cov ntaub. Thaum lub hluav taws xob zoo li qub yog qhov loj, cov hluav taws xob zoo li qub yog ntau npaum li ntau txhiab vim yog kev tawm tsam, ua rau muaj kev tawm tsam.
Nws tau pom tau ntev heev uas thaum ob txoj hauv kev rub tawm ntawm ib leeg thiab cais, cov khoom siab dua, thiab cov khoom noj kom muaj cov khoom tsis zoo. Nov yog kev cai lij choj nrhiav pom nyob rau thaum xaus ntawm lub xyoo pua puv 19, uas yog ua raws li ntau cov kev sim ua ntej ,. Lub electrostatic muaj peev xwm ua ntu zus ntawm ntau yam fibers tau txais los ntawm kev sim yog qhia hauv Table 3-32 (cov kev sim ntsuas kub thiab huab cua tus kwv tij thiab huab cua txheeb ze ntawm 33%. Thaum ob hom fibers nyob rau hauv lub rooj yog nyob rau hauv kev sib txhuam, cov fibers nyob rau sab saum toj ntawm lub rooj yog muaj txiaj ntsig zoo them thiab cov ntsiab lus hauv qab no yog qhov tsis zoo.
Cov lus 1 Fiber electrostatic muaj peev xwm ua tau
Cov plaub yaj, nylon, viscose, paj rwb, siving, polyacrylonitrile, chlorine, vinylpolype, fluorine, fiber

Thawj zaug muaj peev xwm lub rooj hauv 1757, muaj tsuas yog cov ntaub plaub ua cov khoom siv textile, tau npaj rau ntawm qhov ze zoo kawg ntawm lub rooj. Coob tus neeg tau ua tiav kev tshawb fawb hauv daim teb no yav tom ntej. Hauv qee qhov kev tshaj tawm cov peev xwm ua ntu zus, kev npaj ua ke ntawm ntau yam fibers tsis yog tib yam, thiab qee qhov sib txawv yog qhov loj. Tab sis feem ntau hais lus, polyamide fibers (cov plaub tsiaj, cov kab mob bibulose tau npaj rau hauv nruab nrab, thiab cov saw hlau fibers tau teem rau ntawm qhov tsis zoo them ntawm qhov chaw tsis zoo. Nws yuav tsum raug sau tseg tias kev hloov pauv me ntsis ntawm kev sim cov xwm txheej yuav ua rau cov kev hloov ntawm cov muaj zog fiber ntau. Thiab tom qab cov khoom siv textile tau raug them, lub peev xwm ntawm txhua feem ntawm cov khoom siv tsis zoo, qee qhov yuav muaj qhov tsis zoo them nqi, qhov xwm txheej nyuaj dua.
Lub "lub zog" ntawm cov hluav taws xob zoo li qub nqa los ntawm cov ntaub ntawv them nqi yog qhia los ntawm tus nqi them (coulomb lossis chav tsev hluav taws xob) ntawm cov khoom siv phaus (lossis ib cheeb tsam chaw). Qhov siab tshaj plaws hluav taws xob ntawm txhua hom fibers yog ze li sib npaug, tab sis cov hluav taws xob hluav taws xob tsis ncaj. Qhov tseem ceeb txiav txim siab tus nqi electrostatic lwj yog qhov saum npoo tshwj xeeb ntawm cov khoom siv. Qhov kev sib raug zoo ntawm qhov tshwj xeeb tsis kam ntawm qee cov ntaub thiab ib nrab lub sijhawm uas yuav tsum muaj rau electrostatic lwj mus rau ib nrab ntawm tus nqi qub.
Lub logarithmic kev sib raug zoo ntawm tus nqi ib nrab - lub neej ntawm ntau cov fabrics thiab cov npoo kev sib raug zoo yog txoj kev sib raug zoo. Qhov loj dua qhov loj dua tsis kam yog, ntev ntev ib nrab- lub neej yog. Cov lus 1 qhia qhov kev sib raug zoo ntawm cov nplaim hluav taws xob tsis kam ntawm qee cov ntaub thiab tus nqi ib nrab ntawm lub neej (kev ntsuas kub (ntsuas kub). Thaum kev sib txhuam tau tshwm sim ntawm ob fibers nyob rau hauv lub rooj, cov fibers teem rau saum npoo yog qhov zoo them thiab cov fibers hauv qab no yog qhov tsis zoo.
Lub "lub zog" ntawm cov hluav taws xob zoo li qub nqa los ntawm cov ntaub ntawv them nqi yog qhia los ntawm tus nqi them (coulomb lossis chav tsev hluav taws xob) ntawm cov khoom siv phaus (lossis ib cheeb tsam chaw). Tus nqi them siab tshaj plaws ntawm txhua hom kev sib tw yog ze li sib npaug, tab sis tus nqi tsis zoo ntawm cov hluav taws xob zoo li qub yog qhov sib txawv heev. Qhov tseem ceeb txiav txim siab tus nqi electrostatic lwj yog qhov saum npoo tshwj xeeb ntawm cov khoom siv.
Qhov loj dua qhov loj tsis kam ntawm cov ntaub, ntev ntev dua ib nrab - lub neej ntawm tus nqi. Yog li ntawd, yog hais tias qhov tshwj xeeb tiv taus ntawm cov ntaub qhwv kab yog txo kom qee qhov ntev, electrostatic tshwm sim tuaj yeem tiv thaiv tau.
Txoj kev xyaum ntau lawm qhia tau hais tias kev ua ntawm cov cellulose fiber ntau hauv Textile Mill yog tsawg tsawg tus hluav taws xob. Ua xws li cov ntaub plaub thiab cov kab muag muag thiab muaj qee yam kev cuam tshuam hauv hluav taws xob. Txawm li cas los xij, kev ua cov polyester, nylon, polyester thiab lwm cov hluavtaws hluavtaws yog raug rau qhov kev cuam tshuam hluav taws xob zoo tshaj plaws.
Txhawm rau kom daws cov hluav taws xob hluav taws xob hauv cov txheej txheem hluavtaws fiber ntau, nws yog qhov tsim nyog los ua hluavtaws fiber thiab nws cov ntaub muaj qhov ua tiav thiab cov tshuaj tiv thaiv kev ua haujlwm. Muaj ntau txoj hauv kev los ua cov hluavtaws fibers thiab lawv cov ntaub muaj cov tshuaj tua kab mob tsis ntev. Piv txwv li, thaum cov hluavtaws fiber yog polymerized los yog spun, ib lub polymer hydrophilic lossis cov tshuaj pleev cov roj ntsha tsis tau ntxiv; Los yog ib qho kev sib xyaw nrog cov txheej txheem hydrophilic sab nraud yog tsim los ntawm cov txheej txheem sib xyaw. Piv txwv li, hauv cov txheej txheem ntawm kev tig, lub suab hluavtaws tuaj yeem sib xyaw nrog cov peev txheej noo, thiab raws li cov ntaub ntawv tsis zoo, thiab cov ntaub tuaj yeem kho nrog cov dej khov kho hydrophilic.
Nws muaj peb hom tshuaj tua kab mob hauv khw muag khoom: Antistatic cov ntaub nrog cov xaim hlau, cov tshuaj tiv thaiv kab hlau nrog cov ntaub ntawv siv fiber ntau thiab cov tshuaj tiv thaiv nrog kev ua tiav.
