Taw qhia: Knitting yarn yuav tsum muaj ntau dua qhov sib npaug, zoo softness, qee lub zog, extensibility, thiab twist. Nyob rau hauv tus txheej txheem ntawm kev tsim knitted ntaub ntawm lub tshuab knitting, cov xov paj yog yuav luag txhua yam kev ua, xws li stretching, dabtsi yog khoov, thiab twisting. , Kev sib txhuam, thiab lwm yam. Txhawm rau kom ntseeg tau tias cov khoom lag luam ib txwm muaj thiab cov khoom zoo, cov xov paj knitting yuav tsum ua raws li cov cai hauv qab no:
1. Cov xov paj yuav tsum muaj zog thiab extensibility
Cov xov paj lub zog yog qhov tseem ceeb ntawm qhov zoo ntawm cov xov paj knitting. Txij li cov xov paj tau dhau los ntawm qee qhov nro thiab rov ua dua thaum lub sijhawm npaj thiab xaws, cov xov paj knitting yuav tsum muaj qee lub zog. Tsis tas li ntawd, cov xov paj kuj raug khoov thiab torsion deformation thaum lub sijhawm knitting. Yog li ntawd, cov xov paj knitting yuav tsum muaj qee qhov kev nthuav dav, yog li txhawm rau khoov rau hauv lub voj voog thaum lub sijhawm knitting thiab txo cov xov paj tawg.
2. Cov xov paj yuav tsum muaj softness zoo
Qhov softness ntawm knitting yarn yog siab dua li ntawm cov xov paj. Vim hais tias cov xov paj mos yog ib qho yooj yim rau khoov thiab ntswj, lub voj qauv hauv cov ntaub knitted yog ib yam, cov tsos yog meej thiab zoo nkauj, thiab cov xov paj tawg thaum lub sij hawm weaving txheej txheem thiab kev puas tsuaj rau lub voj voog txoj kev tshuab tuaj yeem txo.
3. cov xov paj yuav tsum muaj qee qhov twist
Feem ntau hais lus, qhov twist ntawm knitting yarn yog qis dua li ntawm cov xov paj. Yog hais tias tus twist loj dhau lawm, lub softness ntawm cov xov paj yuav tsis zoo, nws tsis yooj yim rau bent los yog twisted thaum lub sij hawm weaving, thiab nws yog ib qho yooj yim los tsim kinks, ua rau weaving tsis xws luag thiab puas lub knitting koob; Tsis tas li ntawd, cov xov paj nrog cov twist loj heev yuav cuam tshuam rau elasticity ntawm knitted ntaub. , Thiab ua kom lub coil skew.
Txawm li cas los xij, qhov sib tw ntawm cov xov paj knitting yuav tsum tsis txhob qis dhau, txwv tsis pub nws yuav cuam tshuam rau nws lub zog, ua rau kom tawg thaum lub sij hawm xaws, thiab cov xov paj yog loj, ua rau cov ntaub yooj yim rau fluff thiab pilling, thiab txo qhov hnav ntawm cov ntaub knitted. . Yog li ntawd, kev xaiv kom raug ntawm twist yog ib txoj hauv kev tseem ceeb los xaiv cov xov paj tsim nyog. Kev siv cov knitted fabrics txawv, thiab cov kev xav ntawm twist kuj txawv.
(1) Ib lub tsho yuav tsum smoothness, compactness, du nto thiab meej zoo nkauj. Qhov twist ntawm cov xov paj yuav tsum loj dua, uas tuaj yeem nyob ze rau ntawm cov xov paj warp rau kev sib tw nrog tib txoj kab ceev.
(2) Kev sib tw ntawm cov xov paj rau cov khaub ncaws sab nrauv yuav tsum loj dua los txhim kho qhov nkig thiab txhim kho qhov tshwm sim ntawm pilling.
(3) Cov ntaub ntaub paj rwb thiab ntaub elastic yuav tsum yog mos thiab hloov tau, thiab qhov sib tw ntawm cov xov paj yuav tsum qis dua me ntsis. Feem ntau, qhov sib txawv ntawm qhov sib txawv ntawm qhov sib tw ntawm cov xov paj weft rau weaving nrog tib txoj kab ceev yog siv. Cov xov paj siv rau pawg knitted fabrics yog los pab txhawb pawg, thiab ua kom cov pawg tuab tuab, thiab qhov xav tau sib tw me dua.
Tsis tas li ntawd, tus nqi ntawm twist sib txawv nrog cov xov paj linear ntom.
4. linear ntom ntom ntawm cov xov paj yuav tsum tsis sib xws thiab cov xov paj tsis zoo yuav tsum tsawg dua
Lub uniformity ntawm cov xov paj linear ntom, uas yog, lub uniformity ntawm cov xov paj evenness, yog ib qho tseem ceeb zoo qhia ntawm knitting yarn. Cov xov paj zoo sib xws yog qhov zoo rau knitting thiab ua kom cov ntaub zoo, yog li lub voj qauv zoo ib yam thiab daim ntaub nto meej.
Yarn defect is also an important indicator of card clothing yarn. If there are thick knots on the yarn, the knitting cannot pass smoothly, resulting in yarn breakage or damage to the machine parts, and it is easy to form "stripes" and "clouds" on the cloth surface, reducing the quality of the knitted fabric; For details, the strength is insufficient here, and the ends are easily broken, which affects the quality of the fabric and reduces the productivity of the machine. Because there are multiple loop forming systems on the knitting machine to feed yarn into loops at the same time, it is not only required that the yarn thickness of each path is uniform, but also the thickness difference of the yarns between the paths must be strictly controlled, otherwise horizontal stripes will be formed on the cloth surface. Defects such as shadows reduce the quality of the fabric.
5. Cov xov paj yuav tsum muaj cov dej noo zoo
Lub peev xwm ntawm cov xov paj kom nqus dej noo hauv huab cua yog hu ua hygroscopicity. Lub peev xwm nqus dej noo ntawm ntau cov fibers sib txawv heev, thiab qhov nqus dej noo sib txawv nrog qhov kub thiab av noo ntawm huab cua. Cov xov paj siv rau knitting ntau lawm yuav tsum muaj qee qhov kev nqus dej noo. Nyob rau hauv tib qhov txheeb ze av noo, cov xov paj nrog zoo hygroscopicity, ntxiv rau nws cov hluav taws xob zoo conductivity, kuj yog conducive rau lub stability ntawm cov xov xov twist thiab kev txhim kho ntawm extensibility, thiaj li hais tias cov xov paj muaj zoo weaving zog.
6. cov xov paj yuav tsum muaj qhov ua tiav zoo thiab me me coefficient ntawm kev sib txhuam
Cov xov paj knitting yuav tsum tsis muaj impurities thiab roj stains li sai tau, thiab yuav tsum tau du heev. Cov xov paj uas tsis yog- cov xov paj du tuaj yeem ua rau lub tshuab ua haujlwm hnyav, yooj yim ua rau lub tshuab ua haujlwm, 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 kev tsim khoom ntawm knitting. tshuab thiab qhov zoo ntawm cov ntaub.
