Tam sim no, feem ntau roving thav duab siv cov cuab yeej siv tshuab lossis hluav taws xob los ntsuas thiab tswj cov xov paj me me, nruab nrab thiab loj. Cov thav duab roving tam sim no siv los ntawm peb lub tuam txhab yog JWF1415 los ntawm Tianjin Hongda thiab FA491 los ntawm Qingdao Huanqiu. Nyob rau hauv qhov tseeb, lawv muaj nyob rau tib lub series, tshem tawm cov neeg kho tshuab cov qauv xws li kev sib sau, sab sauv thiab sab lub khob hliav qab lub log, lub khob hliav qab log tswj thiab ntev meter. Lawv cov haujlwm sib thooj yog ua tiav los ntawm cov khoos phis tawj. Hom tshiab roving thav duab lub stretch nrhiav thiab tswj txoj kev yog ntau yooj yim, advanced thiab raug. Txoj kev ntsuas dav dav roving elongation yog txoj kev ntsuas qhov ntev. Lub koos pij tawj ntawm tus tshiab roving thav duab muaj qhov tshwj xeeb tswj module los ntsuas roving elongation, uas yooj yim rau siv thiab txhim kho qhov kev sim ua haujlwm.
Qhov nruab nrab roving elongation yog ntsuas ib los ntawm ib qho nrog txoj kev ntsuas qhov ntev. Cov combed ntau yam ntawm lub tuam txhab yuav tsum yog 1 feem pua ~ 2 feem pua. Qhov sib txawv elongation ntawm pem hauv ntej thiab nram qab kab thiab nruab nrab ntawm cov xov paj loj thiab me yuav tsum tsis txhob ntau tshaj 1 feem pua, tus nqi tsim nyog ntawm lub hli rov elongation yuav tsum yog 80 feem pua, thiab qhov tsim nyog tus nqi ntawm elongation sib txawv yuav tsum yog 90 feem pua, uas yuav tsum tau kho. yog tias nws tshaj qhov ntau.
03 tswj txoj kev roving elongation
Lub roving zoo ntawm thawj combed ntau yam yog: roving elongation 2.33 feem pua. Qhov elongation tsim nyog tus nqi yog 34 feem pua, qhov sib txawv elongation tus nqi yog 1.2 feem pua, qhov sib txawv elongation tsim nyog tus nqi yog 64 feem pua, lub roving evenness yog 3.84 feem pua, lub internal unevenness ntawm roving yog 1.0 feem pua, thiab roving tawg kawg yog 1.5 daim / 100 spindles.
Vim qhov kev hloov pauv loj ntawm ntau yam roving indexes thiab spinning zoo, nws tau pom los ntawm kev txheeb xyuas cov ntaub ntawv txhua hli uas roving elongation Performance index tau ua tsis zoo, thiab qhov elongation thiab qhov sib txawv tsim nyog tus nqi tau tshaj tus qauv ntau. Yog li ntawd, peb pib tswj roving elongation, thiab tom qab ntawd tswj kev sib tsoo. Ua ntej, peb ua cov txheeb cais thiab Kev Ntsuas ntawm cov ntaub ntawv ntawm 10 # thiab 11 # roving thav ntawv, thiab cov txiaj ntsig tau qhia hauv Table 1.
duab
Nws tuaj yeem pom los ntawm cov lus 1 tias muaj qhov sib txawv me ntsis ntawm qhov loj ntawm cov kab hauv ntej thiab nram qab ntawm 10 \roving thav duab, tab sis qhov nruab nrab elongation yog sab nraum qhov kev tswj, thaum qhov sib txawv ntawm qhov loj ntawm 11 \roving ncej loj. Tom ntej no, qhov txuas ntxiv yog kho thiab tswj. Txoj kev hloov ntawm tus tshiab roving thav duab yog txawv ntawm cov tsoos roving ncej, tab sis lub hauv paus ntsiab lus yog tib yam. Noj JWF1415 ua piv txwv, qhov nro tswj tsis tau ntawm roving ncej yog: kos duab coefficient, thickness ntawm txhua txheej, bobbin txoj kab uas hla, thiab lwm yam.
Cov txheej txheem kev coefficient P cuam tshuam rau tag nrho cov xov nro, yog tias qhov nro P txo; Yog tias qhov nro yog xoob, P nce. Lub thickness ntawm txhua txheej cuam tshuam cov xov nro. Yog tias qhov nro yog nruj, lub thickness ntawm txhua txheej nce; Yog tias qhov nro yog xoob, lub thickness ntawm txhua txheej yog txo. Txoj kab uas hla ntawm bobbin cuam tshuam rau cov xov paj me me. Yog hais tias qhov nro yog nruj, txoj kab uas hla ntawm lub bobbin nce; Yog hais tias qhov nro yog xoob, txoj kab uas hla ntawm bobbin txo.
Ua ntej, xyuas qhov axial winding ceev ntawm ob lub tsheb ntawm hom no. Txoj kev tshuaj xyuas yog tias thaum cov xov paj me me, muaj qhov sib txawv tsawg dua {{0}}.5mm ntawm cov xov paj uas nyob ib sab. Nrog rau qhov muag liab qab, qhov saum npoo ntawm bobbin tuaj yeem pom faintly thaum winding thawj txheej. Thaum lub iav ntawm qhov winding tau txiav txim siab, pib kho cov elongation ntawm cov xov paj loj, nruab nrab thiab me. Tus thawj tsis nyob rau hauv lub tsheb yog raws li nram no: daim ntawv coefficient P yog 1.02; Lub thickness ntawm txhua txheej yog 0.421mm, thiab txoj kab uas hla ntawm bobbin yog 44.05mm; Lub thickness ntawm txhua txheej yog 0.428mm, thiab txoj kab uas hla ntawm bobbin yog 44.16mm.
Ua ke nrog qhov elongation thiab qhov sib txawv ntawm cov xov paj loj thiab me ntawm txhua lub tshuab, ntau qhov kev ntsuas qhov ntsuas qhov ntsuas qhov ntsuas tau ua tiav. Nws yog suav hais tias yog cov nram qab no configurations yog zoo rau roving zoo. Cov txheej txheem kho winding tsis yog: 10 \. Yog li ntawd, cov txheej txheem winding tsis ntawm no ntau yam tau hloov kho los tswj lub roving elongation thiab txhim kho cov roving zoo. Saib Table 2 rau qhov hloov kho 10\ thiab 11\.
duab
Lub hli rov qab zoo indexes tom qab hloov kho yog raws li nram no: roving elongation 1.81 feem pua, elongation tsim nyog tus nqi 90 feem pua, elongation txawv tus nqi 0.7 feem pua, elongation txawv tsim nyog tus nqi 100 feem pua, roving evenness 3.54 feem pua, roving unevenness 0.7 feem pua, roving breakage tus nqi 0.8 pieces / 100 spindles · H. Cov txiaj ntsig tau pom tias los ntawm optimizing cov txheej txheem tsis ntawm winding ib feem, roving elongation thiab elongation sib txawv tus nqi loj thiab me. yarns tau tswj tau zoo, roving evenness thiab zoo unevenness yog txhim kho, lub roving breakage yog txo, thiab cov efficiency ntau lawm.
04 xaus
(1) Cov txheej txheem tsis sib xws ntawm winding ib feem ntawm roving ncej ntawm tib hom thiab qauv yuav tsum tau teem nyob rau hauv tib txoj kev. Feem ntau, roving elongation yog qhov pib tsis hloov tom qab hloov kho.
(2) Lub roving elongation yuav tsum tau kho thaum lub txheeb ze av noo nyob rau hauv lub rhiav hloov zoo heev, ntau yam (fiber hom los yog ntev hloov heev), thiab lub tshiab tshuab mus sib tw spinning los yog xeem elongation yog heev txawv ntawm lub hom phiaj.
(3) Thaum kho roving elongation, axial winding ceev yuav tsum tau kho ua ntej, ces qhov elongation ntawm cov xov paj me me, thiab thaum kawg lub elongation ntawm cov xov paj nruab nrab thiab cov xov paj loj. Txawm li cas los xij, cov txheej txheem winding yuav tsum tau ua raws li qhov xwm txheej tiag tiag thiab kev ntsuas kev ua kom zoo yuav tsum tau ua. Cov ntaub ntawv yuav yeej.
