Cov yam ntxwv thiab cov kev xav tau ntawm knitting yarn

Knitted fabric yarns, raws li lub npe qhia, yog spun yarns siv los tsim knitted fabrics kom paub qhov txawv ntawm woven yarns. Vim tias qhov sib txawv ntawm cov khoom siv knitted fabrics thiab cov khoom siv woven, cov xov paj spinning tau raug sib txawv zog thaum lub sijhawm tsim khoom. Nyob rau tib lub sijhawm, vim muaj cov yam ntxwv sib txawv thiab siv cov ntaub knitted thiab woven fabrics, knitted fabric yarns muaj cov yam ntxwv thiab cov cai hauv qab no. 1. Knitted npuag muaj qee lub zog thiab elongation. Lub zog ntawm cov xov paj spun yog ib qho tseem ceeb zoo qhia rau cov xov paj rau knitted fabrics. Txij li cov xov paj spun yog raug rau ib qho kev nro thiab rov ua dua thaum lub sijhawm npaj thiab xaws, cov xov paj rau knitting yuav tsum muaj qee lub zog. Tsis tas li ntawd, cov xov paj spun yog raug khoov thiab torsional deformation thaum lub sij hawm knitting txheej txheem, thiab yog li ntawd cov xov paj rau knit fabric yuav tsum muaj ib tug tej yam elongation thiaj li yuav tsum tau khoov mus rau hauv ib lub voj thaum lub sij hawm weaving txheej txheem thiab kom txo tau lub breakage. ntawm spun yarn. 2. Knitted npuag xov paj muaj qhov yooj yooj yim. Qhov softness ntawm cov xov paj rau knitting yog siab dua li cov xov paj woven. Vim hais tias cov xov paj mos spun yog ib qho yooj yim rau khoov thiab twist, thiab cov qauv coil nyob rau hauv cov ntaub knitted yog ib yam, cov tsos yog meej thiab zoo nkauj, thiab breakage ntawm spun yarn thiab kev puas tsuaj rau lub voj sib sau tshuab thaum lub sij hawm weaving txheej txheem yuav txo. 3, knitted fabric yarn muaj ib co degree ntawm twist Feem ntau hais lus, cov xov paj ntawm knitted ntaub muaj ib tug qis twist tshaj lub woven yarn. Yog hais tias tus twist loj dhau lawm, qhov softness ntawm spun yarn tsis zoo, nws tsis yooj yim rau bent thiab twisted thaum lub sij hawm weaving, thiab kinking yog yooj yim tshwm sim, ua rau woven woven npuag yuav ua rau lub knitting koob; Tsis tas li ntawd, cov xov paj ntau dhau spun cuam tshuam rau cov ntaub knitted. Lub elasticity ntawm cov khoom thiab skew ntawm lub kauj. Txawm li cas los xij, qhov sib tw ntawm cov xov paj rau cov ntaub knitted yuav tsum tsis txhob qis dhau, txwv tsis pub lub zog yuav raug cuam tshuam, kev tawg thaum lub sij hawm xaws yuav nce ntxiv, thiab cov spun yarn yuav loosened, yog li cov ntaub tuaj yeem yooj yim pilling thiab cov xov paj. hnav cov cuab yeej ntawm cov ntaub knitted tuaj yeem txo. Yog li ntawd, kev xaiv kom raug ntawm twist yog ib txoj hauv kev tseem ceeb rau rationally xaiv spinning yarn. Kev siv cov knitted fabrics txawv, thiab cov kev xav ntawm twist kuj txawv. Lub tsho yuav tsum muaj qhov du, nruj, huv si, cov kab ntshiab, thiab qhov sib tw ntau dua ntawm cov xov paj, uas yog ze rau tus qauv warp yarn rau tib txoj kab nrib pleb. Kev sib tw ntawm cov xov paj spun ntawm cov khaub ncaws sab nrauv yuav tsum tau ua kom loj dua los txhim kho qhov nruj thiab txhim kho qhov tshwm sim pilling. Cov ntaub paj rwb thiab ntaub elastic yuav tsum yog mos thiab elastic, thiab twist ntawm cov xov paj yuav tsum qis dua me ntsis. Feem ntau, qhov sib txawv ntawm qhov sib txawv ntawm cov xov paj weft twist ntawm tib txoj kab nrib pleb yog saws. Cov xov paj rau pawg knit npuag yog tsim los rau kev yooj yim ntawm txhuam, thiab cov tuab ntawm pawg yog sib xws, thiab qhov xav tau kev sib tw me dua. Qhov loj ntawm lwm cov twists kuj txawv nrog cov linear ceev ntawm spun yarn. Feem ntau twists ntawm yarns rau knitted fabrics yog qhia nyob rau hauv lub rooj hauv qab no. 4. Lub linear ceev ntawm knitted fabric yarn yog uniform thiab cov xov paj tsis xws luag yog me me. Lub uniformity ntawm linear ceev ntawm spun yarn yog uniformity ntawm spun yarn, uas yog ib qho tseem ceeb Performance index ntawm cov xov paj rau knitted ntaub. Qhov sib npaug spun yarn yog qhov zoo rau kev ua tiav cov ntaub knitted thiab ua kom cov ntaub zoo, yog li cov qauv coil yog qhov sib xws thiab daim ntaub nto meej. Yog tias muaj ntu tuab ntawm cov xov paj, cov xov paj yuav tsis dhau mus zoo, ua rau cov xov paj tawg lossis puas lub tshuab, thiab "kab kab rov tav" thiab "huab chaw" tsuas yog tsim rau ntawm daim ntaub nto kom txo tau qhov zoo ntawm cov xov paj. knitted ntaub; Nrog cov ntsiab lus, muaj lub zog tsis txaus ntawm no, kev so yooj yim, cuam tshuam rau qhov zoo ntawm cov ntaub thiab txo cov tshuab tsim khoom. Vim hais tias lub tshuab knitting muaj ntau txoj kev looping system thiab cov xov paj yog looped tib lub sij hawm, tsis tsuas yog lub thickness ntawm txhua spun yarn yuav tsum tau uniform, tab sis kuj lub thickness sib txawv ntawm spun yarn ntawm txoj kev yuav tsum nruj me ntsis. tswj, txwv tsis pub nws yuav tsim rau ntawm daim ntaub nto. Kab rov tav kab txaij, duab ntxoov ntxoo thiab lwm yam rickets, txo cov ntaub zoo. 5. Knitted yarns muaj hygroscopicity zoo Lub peev xwm ntawm spun yarn kom tshem tawm cov dej noo hauv huab cua yog hu ua hygroscopicity. Lub peev xwm hygroscopic ntawm ntau cov fibers sib txawv heev, thiab qhov nqus ntawm noo noo sib txawv nrog qhov kub thiab av noo ntawm huab cua. Cov xov paj spun siv hauv kev tsim cov ntaub knitted yuav tsum muaj qee yam hygroscopicity. Nyob rau hauv tib qho kev txheeb ze av noo, cov xov paj spun nrog zoo hygroscopicity tsis tsuas yog muaj hluav taws xob zoo dua, tab sis kuj pab txhawb kev ruaj ntseg thiab elongation ntawm cov xov paj twisted, yog li cov xov paj spun tau zoo weaving. kev ua tau zoo. 6. Knitted fabrics muaj qhov zoo tiav thiab me me coefficient ntawm kev sib txhuam. Cov xov paj rau knitted fabrics yuav tsum tsis muaj impurities thiab roj stains, thiab yuav tsum du heev. Cov xov paj spun tsis zoo tag nrho, kev hnav ntawm lub tshuab qhov chaw yog qhov phem heev, kev puas tsuaj ntawm lub tshuab qhov chaw yog qhov yooj yim, thiab muaj ntau lub paj ya nyob rau hauv lub rooj cob qhia, uas tsis tsuas yog cuam tshuam rau kev noj qab haus huv ntawm cov neeg ua haujlwm, tab sis kuj cuam tshuam rau cov khoom siv. productivity ntawm lub tshuab knitting thiab qhov zoo ntawm cov ntaub.
