Cov yam ntxwv ntawm rotor (rotor spun) xov paj thiab nws qhov sib txawv tseem ceeb ntawm lub nplhaib spun yarn muaj xws li xya yam: lub zog, sib npaug, hnav tsis kam, elasticity, thiab lwm yam, uas tau piav qhia hauv qab no:
Muaj zog
Vim muaj ntau qhov khoov, looped, folded, thiab qhwv fibers hauv rotor yarns, thiab qhov tsis zoo ntawm fiber ntau hloov ntawm cov txheej sab hauv thiab sab nrauv, thaum cov xov paj raug rau sab nraud, qhov tsis sib xws ntawm fiber ntau tawg yog qhov hnyav heev. , thiab vim qhov kev sib cuag luv luv ntawm cov fiber ntau thiab cov fiber ntau, cov fiber ntau yuav plam thaum raug sab nraud quab yuam, yog li lub zog ntawm rotor yarns qis dua li ntawm lub nplhaib spun yarns. Thaum spinning paj rwb; Lub zog ntawm rotor spun yarn yog li ntawm 10-20 feem pua qis dua li ntawm lub nplhaib spun yarn; Thaum spinning tshuaj fibers, nws yog li ntawm 20-30 feem pua qis dua.
evenness ntawm stripe
Rotor spinning tsis xav tau cov ntawv sau cov menyuam, thiab yog li ntawd tsis tsim cov tshuab thiab cov ntawv sau cov nthwv dej uas lub nplhaib spun yarn muaj. Txawm li cas los xij, yog tias muaj cov impurities nyuaj nyob rau hauv lub coagulation tank, lub sij hawm irregularities sib npaug zos rau ib ncig ntawm lub khob spinning kuj tshwm sim. Tsis tas li ntawd, yog tias daim carding roller cua nyob ib ncig ntawm lub paj, muaj kev sib cais tsis zoo ntawm fiber ntau, los yog muaj qhov tsis sib xws ntawm cov fibers, nws tuaj yeem ua rau tsis sib xws ntawm cov ntxhib thiab cov pob zoo. Txawm li cas los xij, feem ntau, daim npav cov menyuam muaj cov txiaj ntsig zoo, muaj kev sib cais fiber ntau zoo, thiab muaj tsawg dua qhov tsis xws li fiber ntau chips thiab paj rwb strands, uas yog qhov zoo rau qhov sib npaug ntawm qhov sib npaug. Tsis tas li ntawd, muaj kev sib koom ua ke hauv cov txheej txheem condensation ntawm rotor spinning. Yog li ntawd, qhov sib npaug ntawm rotor yarns yog sib xws ntau dua li ntawm cov xov paj xov paj. Qhov nruab nrab Ubbelohde tsis sib xws ntawm nruab nrab mus rau qhov zoo rotor yarns yog 11 mus rau 12 feem pua, qee qhov qis dua 10 feem pua, thaum lub nplhaib spun yarns yog 12 mus rau 13 feem pua.
Tsis tas li ntawd, thaum cov paj rwb nyoos dhau los ntawm lub tshuab spinning pem hauv ntej, nws muaj lub zog ntawm kev qhib thiab tshem tawm impurities, thiab muaj ntau cov impurities tshem tawm, tshwj xeeb tshaj yog los ntawm spinner nrog impurity tshem tawm. Nyob rau tib lub sijhawm, vim kev sib cais ntawm fibers thiab impurities nyob rau hauv lub khob spinning, ib feem me me ntawm hmoov av thiab neps tshuav nyob rau hauv lub khob spinning, yog li cov rotor yarn kuj huv si thiab muaj cov xov paj tsawg dua. Tus naj npawb ntawm cov xov paj tsis zoo hauv rotor yarns tsuas yog 1/4 txog 1/3 ntawm cov xov paj ntawm cov xov paj.
Abrasion tsis kam
Lub abrasion kuj ntawm yarns tsis yog tsuas yog muaj feem xyuam rau lub uniformity ntawm cov xov paj nws tus kheej, tab sis kuj ze ze rau lub xov paj qauv. "Vim tias lub nplhaib spun yarn fibers nthuav tawm cov xov paj tsis tu ncua, thaum rov rubbed, cov kauv fibers maj mam dhau los ua axial fibers, ua rau tag nrho cov xov paj poob twist thiab tawg thiab tawg sai sai." Lub txheej txheej ntawm rotor yarn yog qhwv nrog qhov tsis sib xws winding fibers, yog li cov xov paj rotor tsis yooj yim rau kev tawg, thiab yog li muaj kev hnav zoo. Feem ntau, kev puas tsuaj ntawm rotor yarns yog 10-15 feem pua siab dua li ntawm cov xov paj xov paj. Raws li rau abrasion tsis kam ntawm rotor spun yarn, vim nws qhov ntxhib nto thiab zoo adhesion ntawm cov xov paj, rotor spun yarn muaj kev puas tsuaj zoo dua li lub nplhaib spun yarn.
elastic
Spinning nro thiab twist yog qhov tseem ceeb ntawm cov xov paj elasticity. Feem ntau hais lus, spinning nro yog siab thiab cov xov paj elasticity tsis zoo; High twist thiab zoo yarn elasticity. Vim lub siab spinning nro, fibers nyiam tshaj qhov elastic deformation ntau yam, thiab nws yog ib qho nyuaj rau fibers nyob rau hauv cov xov paj rau xaub tom qab spinning, ua rau tsis zoo elasticity. Cov xov paj muaj ib tug loj twist thiab ib tug loj inclination lub kaum sab xis ntawm lub fiber. Thaum ncab, nws nthuav tawm lub caij nplooj ntoos hlav zoo li elongation, yog li nws muaj elasticity zoo. Rotor yarn belongs rau qis nro spinning thiab muaj ntau twist tshaj lub nplhaib spun yarn, yog li rotor yarn muaj elasticity zoo dua lub nplhaib spun yarn.
twist
Feem ntau, qhov sib tw ntawm rotor yarn yog kwv yees li 20 feem pua ntawm cov xov paj xov paj, uas yuav ua rau muaj teeb meem hauv qee qhov kev ua haujlwm tom qab. Piv txwv li, kev ua ntawm tej pawg ntaub yog nyuaj dua. Nyob rau tib lub sijhawm, kev sib tw siab ua rau cov xov paj xav tias nyuaj, cuam tshuam rau kev xav ntawm cov ntaub. Yog li ntawd, nws yog ib qho tsim nyog los kawm txog kev ntsuas kom txo tau qhov sib tw ntawm rotor yarn thaum kom ntseeg tau tias muaj zog ntawm cov xov paj thiab cov xov paj tawg.
Fluffiness
Lub bulkiness ntawm cov xov paj yog qhia los ntawm qhov tshwj xeeb ntim (c ㎡ / g). Vim qhov tsis zoo ncaj thiab tsis sib xws ntawm cov fibers hauv cov xov paj rotor, qhov nro ntawm cov xov paj thaum sib tw yog me me, thiab txheej txheej yog qhwv nrog winding fibers, yog li cov qauv ntawm rotor yarn yog fluffy. Feem ntau, qhov tshwj xeeb ntim ntawm rotor spun yarn yog li ntawm 10-15 feem pua siab dua li ntawm cov xov paj xov paj.
Dyeability thiab pulp absorption
Vim lub fluffy qauv ntawm rotor yarn, uas muaj zog nqus dej, rotor yarn muaj zoo dyeing thiab sizing zog. Kev siv cov dyes tuaj yeem txo tau los ntawm 15-20 feem pua, thiab qhov loj npaum li cas tuaj yeem txo tau los ntawm 10-20 feem pua .
