Nyob hauv tus txheej txheem dej-dav hlau hauv kev lag luam hauv polyester npuag, nws yooj yim los tsim silk-qhov mob tawg tag, poob pulp, txawv txav ntawm weaving, cracking ncej, thiab lwm yam. Nws ntseeg tias ntau lub tuam txhab tau ntsib cov teeb meem zoo li no. Hauv qab no peb yuav tham txog qhov ua rau thiab npaj cov ntsiab lus sib thooj.
1, wool winding tawg xaus
Nyob rau hauv txheej txheem weaving, nylon, polyester thiab lwm yam khoom cua filaments yog ib qho yooj yim rau tsim ib daim ntawm cov ntaub plaub uas nyob ze ntawm cov ncej thooj thiab cov hlau khov. Feem ntau, tsuas yog qee tus ntawm kaum ntawm tib lub fibers hauv ib qho multifilament uas tsis tawg, txawm tias lwm cov hlwv muaj riam. Nws shears zoo li lub pob txha. Nyob rau hauv loj heev zaum, ob peb multifilaments yog "txiav" ua ke los ua ib daig ntawm cov ntaub plaub, thiab ua tiav kawg.
Lub ntsiab yog vim li cas rau qhov tshwm sim no yog qhov hluav taws xob hluavtaws muaj lub siab tensile lub zog thiab lub siab qis zog. Thaum twg cov yeeb yaj kiab uas ua rau ntawm ib lub xov yog khoov ntawm lwm txoj xov, cov filaments tsis yooj yim tawg vim lub zog tensile lub zog thaum sib cais ntawm ob lub yeeb yaj kiab, tab sis cov kinked fibers yog Lub shearing zog yog tsawg thiab yog "txiav" tshwj xeeb yog cov uas tsis yog sib tw los yog sib tw, qhov sib txuas ntawm fiber ntau yog cov neeg pluag, thiab cov txaj twv lwm tus fibers, yog li "txiav" ntau tshaj ib tus fibers, yog tias tsis kho nyob rau hauv lub sij hawm, Yuav mus rau hauv ib daim ntaub plaub.
Yuav kom tiv thaiv tau cov xov los ntawm tawg thiab tawg, nws yog ib qho tsim nyog yuav tsum tsis txhob npaj txheej txheem thiab lub cim ntawm cov xov paj thaum lub sijhawm. Uas yog ua cov nram qab no:
(1) Txwv tsis pub tswj tus nro ntawm cov xaim hauv kev npaj ua ntej. Nyob rau hauv lub premise ntawm zoo sib sau, lub nro processing ntawm xaim yog me ntsis me. Yog hais tias qhov nro loj heev, cov xov hlau yuav raug rho tawm vim tsis muaj kev nruj tom qab ua haujlwm, thiab lub ntxig phab ntsa Lub phab ntsa tiv thaiv nws tawm ntawm kev tawm, ua rau ib qho "tawg" phenomenon uas nyuaj nrhiav pom. Ntxiv rau kev ua raws li kev tswj nro ntawm cov xov, txoj kev nyuaj yog maj mam nias lub cev nrog tus ntiv tes xoo thiab nruab nrab ntiv tes, thiab qhov xov yog me ntsis sunken. Nws yog ib lub tswv yim kom tiv thaiv kom tsis txhob mob siab.
(2) Daim ntawv qhia xov xwm yuav tsum ua kom sib haum thiab hnav tsis taus thiab siv cov khoom siv zas siab uas tsis yooj yim rau tsim hluav taws xob, kom tsis txhob muaj cov fibers tawg thaum lub sijhawm ua haujlwm. Nyob rau hauv kev, nws yog ib qho tsim nyog los tiv thaiv kev siv cov khoom sib nqus vim nws yog du, tiam sis muag, tsis tuaj yeem tiv kev txhuam ntawm cov hluavtaws fibers, yuav fluff, thiab hnav cov fibers hluavtaws.
(3) Cov yeeb yaj kiab zoo tsim thiab infiltrated rau ntawm qhov tsis ua kom tawv nqaij. Cov kab uas zoo ua tau tuaj yeem tiv thaiv txoj kev tsis sib haum xeeb thiab lub suab sib tw, thaum lub xov tooj cua zoo tau zoo thiab tau tawg hauv ob peb xov. Nyob rau hauv cov ntaub ntawv no, nws muaj peev xwm lo ib plurality ntawm fiber threads kom tsis txhob muaj lub cim ntawm ntaub plaub.
(4) Lub density ntawm lub healds nyob rau hauv lub heal thav duab yuav tsum tsis txhob loj heev. Raws li qhov kev tsim ntawm cov khoom tsim tawm, yog tias qhov kev khov kho ntawm cov tsiaj mob siab tshaj 8 / cm thaum lub sij hawm weaving, nws yuav hais tias yuav muaj kev sib txhuam ntawm cov xov hlau thiab cov healds, nyob ntawm cov xov hlau thiab xov ntawm qhov rov qab qhib. Yuav kom nce qhov naj npawb heald thav ntawv, txoj kev nyuaj yog siv ob chav hlau tuav, uas yog, rau nruab ob txoj kev tuav steel rau ntawm ib qho xwm txheej, thiab cais cov xov hlau xov rau hauv cov hlau tuav, uas yuav txo tau tag nrho cov xov tooj ntawm cov hlau tuav. Lub ntom ntawm cov ntuab tsis pub cov cim ntawm ntaub plaub. Thiab yuav tsum tau hloov cov xwm txheej txhua lub sij hawm kom tsis txhob muaj kev cuam tshuam los ntawm kev "splintered" vim yog txoj kev poob siab.
(5) Rhiav kev toob khawm yuav tsum tswj kom muaj cua kub thiab av noo kom tsis txhob muaj hluav taws xob zoo ntxiv vim yog lub zog hluav taws xob uas tau los ntawm kev ziab ntawm qhov kev cob qhia. Qhov ntsuas ntawm cov txheebze yuav tsum siab, thiab tswj tau kom 70% mus rau 80%.
2, poob pulp
Thaum cov dej ntub dej ntub yog khaus, xim dawb los yog cov cuaj tsuaj, uas yog, ntog slurry, feem ntau tshwm nyob rau hauv cov pob tw thiab hlau khov. Cov slags ua rau lub xov tooj tawg nce thiab nqis thiab nce thiab nqis thaum qhib, uas ua rau muaj qhov tsis muaj tseeb, tawg hlo, tawg tuaj, thiab lwm yam., Loj heev, nws kuj yuav tshwm sim, cuam tshuam yam khoom zoo thiab kev siv zog.

(2) Lub slurry yuav tsum tau softened ua ntej, thiab cov dej hardness yuav tsum tau cia hauv qab 30 mg / kg; lub hau npau npau thiab cov thoob thoob yuav tsum tau ntxuav; cov kauj ruam ntawm cov kauj ruam yog li nram qab no: muab tso rau hauv 75 hauv lub taub dej kub npau npau% dej, pib lub stirrer ntawm 80-120r / min, kub cov dej kom txog 50-60 ° C, muab cov slurry rau hauv cov dej, do rau 15-20min, ntxiv rau lub koom haum, ua rau 15min, ntxiv dej kom 100%. siv.
(3) Cov txheej txheem sizing yuav tsum tau tswj tshwj xeeb rau kev tswjhwm kom tswj tau qhov ntsuas thiab qhov concentration ntawm slurry. Thaum lub sij hawm txoj kev sizing, viscosity ntawm slurry yuav nce vim yog evaporation dej. Dej yuav tsum ntxiv rau kom tsis txhob muaj qhov nce ntxiv, los yog lub pob slurry yuav tsum tau siv los tiv thaiv cov viscosity ntawm rising sai. Yog hais tias lub sij hawm slurry ntev dhau lawm, qis qis qis yuav tsum tau nqa tawm kom tiv thaiv cov slurry ntawm kev ua rau hauv cov txheej qis, uas ua rau cov slurry viscosity ntawm cov txheej uas siv tau tsawg dhau. Lub slurry viscosity haum rau tus txheej txheem yog tus ntsuas loj los tiv thaiv kev ua slurry.
Cov ntsiab lus tseem ceeb yog raws li nram no: Cov pH ntawm cov slurry yog 7 mus rau 8, cov ntsiab lus yog 24% rau 25%, tus nqi qis yog 7% mus rau 8%, thiab 77.7dtex / 24f nylon yarn yog sizing ntawm ib hlau ceev ntawm 100 mus 120 m / min, 166d tex. / 36f Polyester processing xo sizing ceev yog li 80 ~ 90 m / min. Lub hauv paus ntsiab lus ntawm kev tswj elongation yog hais tias nws yog me ntsis loj dua nyob rau hauv rooj plaub ntawm tawg lub taub hau tsis cuam tshuam cov kev ua tau zoo ntawm cov xov. Cov duab ntawm qhov slurry no ua rau muaj peev xwm tiv thaiv tau lub xov tooj cua los ntawm qhov me ntsis elongated thiab stretched thaum lub sij hawm weaving, 77. 7d tex / 24f Cov nylon yarn yog tswj ntawm -0.9% rau 1.2%, thiab 166d tex / 36f polyester processed yarn yog li ntawm 0.6 % rau 1.2%.
(4) Thaum tab tom hlo, ua kom tsis txhob muaj qhov nro ntawm daim tawv tuaj yeem tiv thaiv kom tsis txhob ncaim ntawm zaj duab xis; qhov ceev ntawm cov xov phom loj yuav tsum tsis txhob loj heev, thiab qhov kev kho ntawm qhov kho rau txhua daim yuav tsum tsis txhob muaj ntau tshaj 8 pieces / cm. Yog hais tias nws yog tuab heev, nws yuav tsum tau noj. Rau kev ntsuas, xws li xaiv ob npaug ntawm cov hlau; qhov nruab nrab ntawm qhov sib xyaw ntawm qhov rhiav yog 70% txog 80%, thiab qhov kub yog 24 mus rau 28 ° C.
3, txoj hlab xaim txoj kab txawv txav
Tom qab ntau xyoo siv cov dej dav hlau, ib txhia ntawm cov phom nws cov txav yuav tsim kev txawv txav thaum ua haujlwm. Lub tshuab weaving nyeg yog ntau dua, uas yuav ua rau lub xov hluav taws xob tawg thiab so, thiab lo lo ntxhuav saum npoo tsis zoo. Hneev nti txo cov khoom kom zoo thiab cov khoom ua tau zoo. Lub ntsiab ua rau thiab kev tiv thaiv rau txoj kev txawv txav ntawm kev siv nws lub cav yog raws li nram no:
