Yuav ua li cas soften tshaj -}} dized polyester npuag? Txhim Kho Khov & Sizing Softening Streetions

Tshaj -} sizing yog ib qho teeb meem uas ib txwm muaj (thov kom cov npuag tawv thiab tsis xis nyob rau kov. Txhawm rau txhim kho qhov no, "Sizing softening" (yeej tseem ceeb tsom rau kev ua kom nruj nrog polyester cov yuam sij: Muaj Kub Kub Zog thiab Cov Khoom Siv Hluav Taws Xob ruaj khov. Hauv qab no yog ob qho kev lag luam, kev lag luam {{}}}} {5} {{6} {} {theem kev ua haujlwm.

Cov tswv yim tseem ceeb ntawm cov dej kub desization yog siv cua sov kom ua kom nruj sizing sawv daws sw thiab yaj, tom qab ntawd yaug lawv yooj yim nrog dej. Nws yog maj ntawm polyester (vim tias nws zam cov tshuaj hnyav) thiab ua haujlwm zoo tshaj plaws rau dej {} Soluble sizing lossis solulose derivatives.

Nws ua haujlwm li cas

Cov dej kub nkag mus rau qhov khoob ntawm polyester fibers thiab cov sizing txheej, ua rau cov txiv qaub tsw qab los nqus dej noo, thiab poob nws cov rigidity. Rau cov hmoov txhuv nplej siab - raws li sizing (qee zaum siv nyob rau hauv polyester- Cov hmoov txhuv nplej siab tseem tsis tau softening ntxiv cov ntaub.

1. Padding nrog dej kub: Ua ntej, dhau mus tshaj -}}}}}} Qhov no pab tau sizzing pib ozing tam sim ntawd.
2. Heap & Strawbe: Txav cov ntaub qhwv cov ntaub rau cov tshuaj tiv thaiv kom desizion, heas}}} soluble sizing; rau cov hmoov txhuv nplej siab, tswj hwm 25-40 degree). Cia nws zaum 10-12 teev -} Qhov no muab lub sijhawm txaus los tsoo lub sizing.
3. Tso yaug: Tom qab tsim kom loj hlob, yaug cov ntaub npuag kom huv si nrog chav - qhov kub thiab txias kom ntxuav cov sizing. Rau hmoov txhuv nplej siab, lub teeb thib ob yaug yuav pab tshem ib qho seem ntxiv degraded starch hais.

Ntsiab lus tseem ceeb

Txoj kev no ua tau zoo tshaj plaws rau cov ntaub uas muaj cov khoom siv sodium alginate lossis cellulose derivatives. Rau cov hnub qub ntshiab sizing, txuas ntxiv rau lub sijhawm tsim kom loj hlob ntawm 25-40℃(los txhawb {{} maj maj mam ua rau cov kauj ruam no yuav tawm ntawm seem txhav.

Alkali Deitizing siv sodium thydrocide (zoo li polyacryic cov khoom lag luam uas tsis teb rau dej kub ib leeg. Nws tseem muaj nqi -}}}}}}}}}}}}}}}}}}} mills rov siv cov khib nyiab alkali los ntawm kev tshawb fawb lossis cov txheej txheem nyiam.

Nws ua haujlwm li cas

• Rau hmoov txhuv nplej siab: sodium hydroxide ua rau cov hmoov txhuv nplej siab rau swell thiab tawg sib cais (remolysis), tig cov hmoov txhuv nplej siab rau hauv cov suab thaj soluble.
• Rau cov khoom siv hluavtaws (piv txwv li, polyacrylic acid): alkali reacts nrog cov pab pawg polymer, yaj cov txheej txheem sizing thiab stripping nws los ntawm polyester fibers.

3. Muab tso rau qhov nruab nrab: Tom qab tsim kom loj hlob, yaug cov ntaub rov qab nrog dej sov (40-50 degree) kom txog rau kev sim dej yaug dej nruab nrab (siv PHIC daim ntawv los kuaj). Residual alkali tuaj yeem ua rau ntev-}}}} pa rinss, yog li cov pa yaug tsis huv yog qhov tsis yog}.

Cov Nyiaj Tau: Alkali - kua qaub ua ke tiv (rau polyester- kua rwb sib xyaw ua ke)

Yog tias cov ntaub yog polyester - paj rwb sib xyaw (nrog cov hmoov txhuv nplej siab thiab cov khoom siv kua qaub) tom qab alkali desizing:

• Tom qab yaug cov alkali {-}}}}} Cov ntaub qhwv ntsej muag, ncoo nws nrog dilute sulfuric acid (4-6 g / l) thiab heap nws rau 2-3 teev.
• Cov kauj ruam ntxiv no ntxiv hydrolyzes seem cov hmoov txhuv nplej siab thiab ntxuav tawm ntawm cov paj rwb hauv paj rwb hauv paj rwb fibers}}} Tawm ntawm cov tog ntsej muag thiab nqus tsev ntxhua khaub ncaws.

Polyester lub kub tsis kam (ruaj khov txog 180 degree) cia nws tiv thaiv lub zog, thaum nws yuav tsis txaus siab txhais tau tias nws yuav tsis txaus siab rau hauv dej alkali lossis dej kub. Cov cwj pwm no tau ua ob txoj hauv kev nyab xeeb rau polyester {}} tsis zoo li cov paj rwb, uas yuav tsum tau saib xyuas cov paj rwb ntau dua / tshuaj tswj.

Rau cov lag luam ua haujlwm nrog polyester npuag kev ua tiav - shat rau cov pa roj hmab (zoo li cov ntaub pua chaw (zoo li nws cog lus rau kev sizing thiab tom qab softening. Peb polyester filament thiab staple fibers yog enginged nrog cov kev pheej hmoo ntawm {}} sizing los ntawm dej kub los yog alkali desization. Qhov xwm txheej no txhais tau tias koj tus post - kev kauj ruam (nyiam softening) muaj txiaj ntsig ntau, thiab cov ntaub kawg yog kev xav tau ib qho zoo kawg nkaus. Yog hais tias koj nyob nraum siourcing polyester fibers rau cov ntaub uas xav tau ua kom muaj kev kho kom haum, xav kom muaj cov fiber ntau lossis kuaj cov qauv ntsuas.
