1. Tshem tawm cov impurities
Spinning yog txoj kev kawm ntawm kev ua cov ntaub ntawv ntawm cov ntaub ntawv staple fibers rau hauv cov xov paj, uas feem ntau yog tsim los ntawm ntau cov staple fibers ntawm qhov sib txawv ntawm qhov ntev los ntawm kev sib tw, nrog rau kev sib tw ntev ntev monofilaments. Hauv cov txheej txheem spinning, nws yog thawj zaug uas yuav tsum tau tshem tawm impurities, uas yog, ua ntej ua cov khoom siv raw, tseem hu ua kev npaj cov khoom siv spinning. Cov khoom siv raw khoom sib txawv, hom thiab cov khoom ntawm impurities txawv, thiab cov txheej txheem ua thiab Yuyi kuj txawv. Cov txheej txheem ua ntej ntawm cov khoom siv raw feem ntau suav nrog kev siv lub cev (xws li paj rwb ginning), chemical txoj kev (xws li degumming ntawm hemp, refining ntawm txhob lo lo ntxhuav) thiab ua ke lub cev thiab tshuaj txoj kev (xws li ntxuav thiab de-weeding ntawm ntaub plaub).
2. Loos
Txhawm rau ua cov txheej txheem chaotic thiab kab rov tav zoo sib txuas fibers rau hauv ib qho kev sib txuas ntev, thiab muaj qee yam kev xav tau rau cov xov paj du, nws yog ib qho tsim nyog yuav tsum tig cov block fibers rau hauv ib lub xeev fiber ntau, tshem tawm cov kab rov tav kev sib txuas ntawm fiber ntau raw cov ntaub ntawv, thiab tsim kom muaj ib qho khoom siv. longitudinal kev sib txuas ntawm qhov kawg thiab qhov kawg. Lub qub yog hu ua qhov tso tawm ntawm fibers, thiab tom kawg yog hu ua kev sau ntawm fibers. Kev tso tawm ntawm cov fibers yog kev tshem tawm tag nrho ntawm kev sib txuas ntawm sab nraud ntawm cov fibers, tab sis kev puas tsuaj rau cov fibers yuav tsum raug txo kom tsawg li ntau tau. Kev sau ntawm fibers yog rov tsim kho qhov ntev ntawm cov fibers hauv kev sib txuas, uas yog tas mus li, thiab kev faib tawm ntawm cov fibers hauv cov khoom sib xyaw yuav tsum tsis sib xws, thiab tib lub sijhawm muaj qee qhov linear ntom thiab lub zog. Fiber aggregates, tab sis kuj yuav tsum tau ntxiv ib qho twist. Cov txheej txheem sib dhos tsis ua tiav ib zaug, tab sis tsuas yog ua tiav tom qab ntau cov txheej txheem xws li daim npav, kos duab thiab sib tw.
3. Qhib
Qhib yog qhov rhuav tshem ntawm cov fibers loj rau hauv me me, me me fiber ntau. Hais lus dav dav, degumming ntawm hemp kuj yog ib hom qhib. Raws li qhov qhib kev ua tiav, kev sib txuas ntawm cov fibers thiab cov impurities tsis muaj zog, kom cov impurities raug tshem tawm thiab cov fibers sib xyaw ua ke. Qhov qhib kev txiav txim thiab tshem tawm cov impurities tsis tiav nyob rau hauv ib lub sij hawm, tab sis maj mam ua tiav los ntawm kev tsim qauv tsim ntawm tearing, tshuab, thiab splitting.
4. Carding
Daim npav ua haujlwm yog kom txo qis cov me me thiab cov pob ntawm cov fibers rau hauv ib lub xeev los ntawm ntau lub xeev los ntawm ntau cov koob sib tw ntawm lub tshuab carding, yog li los txhim kho kev tso tawm ntawm cov fibers. Tom qab carding, kab rov tav kev sib txuas ntawm cov fibers tau pib tshem tawm, thiab kev tshem tawm impurity thiab sib xyaw ua haujlwm tau txaus. Txawm li cas los xij, muaj ntau cov fibers uas yog nkhaus thiab hooked, thiab tseem muaj qee qhov kev sib txuas ntawm txhua qhov fiber ntau. Thaum ntxov spinning tshuab
5. Sib
Kev ua haujlwm ntawm lub comber yog siv cov zuag los txhuam ob qhov kawg ntawm cov fiber ntau sib cais hauv lub xeev kom ntxaws ntxiv. Combing machining tuaj yeem tshem tawm cov fibers luv luv thiab nplua impurities hauv qab qee qhov ntev, ua rau cov fibers sib npaug thiab ncaj. Cov tshuaj fibers feem ntau tsis ua tiav los ntawm cov combers vim lawv qhov ntev zoo, ob peb impurities, thiab zoo straightening thiab parallel lub xeev.
6. Kev kos duab
Cov combed strips yog lengthened thiab thinned kom maj mam ncav cuag ib tug predetermined thickness, ib tug txheej txheem hu ua drafting. Nws nteg lub hauv paus rau kev ruaj khov ntawm kev sib txuas tsis tu ncua-rau-kawg ntawm fibers. Txawm li cas los xij, kev tsim qauv yuav ua rau muaj qhov tsis sib xws hauv cov xov paj luv luv, yog li nws yog qhov tsim nyog los teeb tsa cov cuab yeej tsim qauv tsim nyog thiab cov txheej txheem tsis ua haujlwm.
7. Twisting
Twisting yog twist lub whisker nyob ib ncig ntawm nws tus kheej axis, thiaj li hais tias cov fibers thaum uas tig mus rau lub axial kev taw qhia ntawm lub whisker yog muab kauv, thiaj li mus tsim radial siab los txhim kho lub longitudinal kev twb kev txuas ntawm cov fibers.
8. Cua
Cov khoom lag luam ib nrab lossis cov khoom tiav tau raug mob rau hauv ib daim ntawv los pab txhawb kev khaws cia, kev thauj mus los thiab kev ua cov txheej txheem tom ntej, uas yog hu ua winding. Cov txheej txheem winding yuav tsum tau ua tsis tu ncua ntawm lub hauv paus tsis cuam tshuam rau cov khoom tsim tawm thiab cov khoom zoo, thiab kev siv zog yuav tsum tau ua kom ua tiav kev tsim khoom tas mus li ntawm ntau cov txheej txheem los txo cov teeb meem zoo los ntawm cov txheej txheem winding kom ntau li ntau tau. Nyob rau hauv luv luv, cov txheej txheem spinning feem ntau suav nrog raw khoom npaj, qhib, carding, impurity tshem tawm, mixing, drafting, merging, twisting thiab winding, thiab lwm yam., ib co ntawm cov paub tom qab ntau zaus.
