Qhov txawv ntawm Artificial paj rwb thiab paj rwb
Artificial paj rwb feem ntau hu ua viscose fiber. Viscose fiber yog hais txog α-cellulose muab rho tawm los ntawm cellulose raw cov ntaub ntawv xws li ntoo thiab cog ligustilide. Los yog nws yog cov khoom siv fiber ntau uas siv paj rwb linter ua raw khoom los ua cov dope spinning thiab tom qab ntawd ua los ntawm cov txheej txheem ntub dej.
Kev siv paj rwb ntaubpaj rwbraws li raw khoom. Nws yog cov textile uas ua los ntawm weaving warp thiab weft yarns nyob rau hauv weaving tshuab. Tam sim no, raws li lub hauv paus ntawm cov paj rwb, nws tuaj yeem muab faib ua cov paj rwb ib txwm siv thiab siv paj rwb ntaub.
Qhov txawv ntawm Txoj Kev
1.Nto-tiav
Artificial paj rwb ntaub muaj lub hau tiaj tus thiab tsis tshua muaj xov paj. Nws tsis muaj impurities. Nws zoo thiab du. Tab sis nyob rau saum npoo ntawm daim ntaub paj rwb, muaj peev xwm pom paj rwb-noob hull thiab impurities, thiab lwm yam. Qhov saum npoo-tiav tsis zoo li cov ntaub paj rwb.
2.Evenness ntawm xov tooj suav
Cov xov tooj suav ntawm cov ntaub paj rwb dag yog txawm tias. Muaj cov xov paj faults tsawg heev. Tab sis cov xov paj suav ntawm cov ntaub paj rwb tsis zoo li cov ntaub paj rwb, tshwj xeeb tshaj yog cov ntaub ntxhib nruab nrab.
3. Kov
Covkovntawm feem ntau cov paj rwb ntaub yog mos, txawm nws yog nyias los yog tuab. Thaum cov ntaub paj rwb zoo li ntxhib me ntsis.
4. Xim ntxoov ntxoo
Cov luster thiab xim ntawm cov ntaub paj rwb zoo ob leeg yog qhov zoo. Artificial paj rwb ntaub yog ci thiab zoo nkauj dua li paj rwb ntaub.
5.Creasing khoom
Artificial paj rwb ntaub creases yooj yim thiab nws tsis tuaj yeem rov qab tau yooj yim. Cov ntaub paj rwb yog me ntsis wrinkled dua li paj rwb ntaub.
6.Drapability
Lub drapability ntawm cov ntaub paj rwb yog zoo dua li cov ntaub paj rwb.
7. Lub zog
Lub zog ntawm daim ntaub paj rwb yog qis dua li ntawm cov ntaub paj rwb. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig ntub, lub zog ntawm cov paj rwb dag yog qhov tsis zoo. Cov xov paj paj tawg yooj yim dua li cov paj rwb dag. Yog li ntawd, feem ntau cov paj rwb ntaub yog tuab. Nws tsis yog nyias thiab lub teeb xws li paj rwb ntaub thiab flax.
Cov yam ntxwv ntawm paj rwb thiab Artificial paj rwb
Cov yam ntxwv ntawm paj rwb:
1.Cotton fiber ntau muaj cov khoom zoo dua noo noo nqus. Feem ntau, paj rwb fiber ntau tuaj yeem nqus dej los ntawm qhov chaw ib puag ncig. Nws cov dej noo yog 8 ~ 10%. Yog li thaum tib neeg cov tawv nqaij kov cov ntaub paj rwb, nws zoo li mos thiab xis. Yog hais tias cov av noo ntawm cov paj rwb fiber ntau nce, thiab qhov kub ntawm ib puag ncig yog siab dua, tag nrho cov dej hauv cov paj rwb fiber ntau yuav evaporate, uas yuav ua rau cov paj rwb ntaub nyob rau hauv lub xeev sib npaug thiab ua rau tib neeg xis nyob.
2.Cotton npuag muaj cua sov zoo. Nyob rau hauv 110 ℃, nws tsuas yuav ua rau noo noo ntawm lubntaubkom evaporate yam tsis muaj kev puas tsuaj rau fiber ntau. Yog li nyob rau hauv qhov kub thiab txias, ntxuav, thiab lwm yam yuav tsis cuam tshuam cov fiber ntau. Lub tshav kub kuj tseem txhim kho lub durability thiab washability ntawm paj rwb ntaub.
3.Cotton fiber ntau muaj zog tiv thaiv alkali. Nyob rau hauv alkali tov, paj rwb fibers yuav tsis puas.
4.Cotton fiber ntau muaj cov khoom tu cev zoo. Nws yog ntuj fiber ntau, nws cov khoom tseem ceeb yog cov xim ntuj thiab ib qho me me ntawm cov khoom siv quav ciab thiab nitrogen nrog rau cov tshuaj pectic. Los ntawm kev sim thiab xyaum, paj rwb fiber ntau tsis muaj kev khaus lossis kev phiv rau tib neeg daim tawv nqaij. Ntev siv paj rwb fiber ntau tsis muaj kev puas tsuaj rau tib neeg lub cev.
Cov yam ntxwv ntawm Artificial paj rwb:
Artificial paj rwb muaj dyeability zoo thiab brilliance thiab siab xim ceev ceev. Nws yooj yim rau hnav. Nws tsis kam mus rau dilute alkali thiab noo noo adsorption khoom yog ze rau paj rwb. Tab sis nws tsis resistant rau acid. Thiab cov rebound resilience, qaug zog durability thiab ntub mechanical zog yog tsis zoo. Artificial paj rwb tuaj yeem sib xyaw nrog cov tshuaj fibers, xws li polyester fiber, thiab lwm yam.
