Yuav ua li cas thiaj li tsim nyog polyester - rwb grey ntaub? Qhov zoo tshaj enzyme - alkali ua ke ua ke

Desizion yog ib tug ua rau -}} - break pretreatment kauj ruam rau polyester- cov paj rwb grey npuag. Thaum lub sij hawm weaving, sizing cov neeg (zoo li cov hmoov txhuv nplej siab rau paj rwb thiab PVA / acryles) lub tsho tiv no rau, lawv rhuav tshem qhov muag, luam ntawv ntxiv, lossis sau tiav. Rau cov kab no npuag, covenzyme - alkali ua ke desization cov txheej txheemyog tus qauv kub: nws lub hom phiaj ob hom sizing cov neeg sawv cev yam tsis muaj kev puas tsuaj ntawm ib leeg {}}}}}}}}}}}}}}}}}}}}}} Cov txheej txheem kev phom sij) thaum txiav rau qhov zas xim txawv tom qab. Cia peb tsoo nws ua haujlwm li cas, kauj ruam los ntawm kauj ruam.

 

Txhua kauj ruam yog txiav kom sib npaug thiab fiberion tiv thaiv -} tam sim no yog cov ncauj lus kom ntxaws:

 

1. Kev hu nkauj ua ntej (thawj prepreatment (thawj prep)

Ua ntej kev tsim nyog, cov ntaub npuag mus los ntawm kev hu nkauj: ib qho kev hla dhau ntawm cov nplaim hluav taws lossis cov menyuam kub kom hlawv tawm saum toj fuzz. Cov kauj ruam no tsis yog - kev sib ceg: Fuzz ntaus sizing cov neeg sawv cev tsis sib xws, ua rau pom kev cia siab tom qab. Los ntawm kev tshem cov fuzz, cov ntaub txaij ua kom du, kom ua kom cov tshuaj yuj tau ncav cuag txhua feem ntawm cov paj dawb.

 

2. Enzyme desization (lub hom phiaj starch rau paj rwb)

Tom ntej no, cov ntaub yog raus rau hauv ib qho - Amylase Enzyme da dej (lub ntsiab sizing tus neeg sawv cev rau cov paj rwb). Cov xwm txheej yog meej meej:

 

• Kub: 50-60℃(sov txaus kom ua kom cov enzyme, tsis kub txaus rau nws)
• PH: 6.0-7.0 (nruab nrab ntau yam kom ua rau enzyme ruaj khov)
• Sijhawm: 20-30 feeb (ntev txaus kom tawg cov hmoov txhuv nplej siab rau hauv cov piam thaj soluble, uas ntxuav tau yooj yim)

 

Cov kauj ruam no nplooj tawm ntawm cov khoom siv sizing (zoo li PVA rau polyester) undouched {} Tab sis yog kev puas tsuaj nrog cov hmoov txhuv nplej siab, yog li polyester fibers nyob tsis muaj mob.

 

3. Alkali Desizing (Part Synthetic Sizing rau Polyester)

Tom qab kev kho enzyme, cov ntaub txav mus rau ib tug alkali da dej los txhawm rau txhawm rau qhov tseem tshuav pva lossis acrylate sizing. Cov ntsiab lus tseem ceeb ntawm no yog:

 

• Kub: 80-90℃(tshav kub pab kom yaj cov khoom siv hluavtaws sizing)
• Alkali concentration: 20-30g / u naoh (sodium hydroxide, muaj zog txaus kom tawg cia kom tsis txhob muaj paj rwb puas)
• Sijhawm: 15-20 feeb (txaus kom yaj cov hluavtaws tsis muaj cov paj rwb rau cov paj rhiab rau cov tshuaj muaj ntshav)

 

Qhov no kaujs ua tiav cov enzyme theem txig - ua ke, lawv tshem tawmob yamhmoov txhuv nplej siab thiab hluavtaws sizing.

 

4. Kub & Dej Txias Rinsing (Tshem Tawm Ntawm Cov Khoom seem)

Cov seem ntawm cov enzymes, alkali, lossis tawg - down down sizing tom qab cov txheej txheem (piv txwv li, alkali residue ua paj rwb brittle). Yog li cov ntaub tau txais ob qho kev yaug:

 

• Ua ntej: 80-95℃dej kub (yaj thiab ntxuav kom deb li qub soluble sizing thiab enzyme)
• Thib ob: Dej txias (txias cov ntaub thiab yaug tawm ib qho kawg ntawm Alkali, nqa cov ntaub rov qab mus rau qhov nruab nrab ntawm pH)

 

Skipping cov kauj ruam no yog ib qho yuam kev - cov seem me me me me uas ua rau tsis muaj qhov nplawm lossis cov fibers tsis muaj zog.

 

5. Kom qhuav & teeb tsa (Npaj zaum kawg rau cov kauj ruam tom ntej)

Kawg, cov ntaub yog qhuav ntawm qhov kub thiab txias (nyob ib ncig ntawm 100-110 degree) thiab maj mam teeb tsa kom tshem tawm ntau dhau noo noo. Ntub ntaub qhwv tau yooj yim, thiab wrinkles tuaj yeem nres cov seem lossis ua kom qhuav cov nplais pob thiab npaj rau Dyeing lossis luam ntawv.

 

Cov tswj tseem ceeb rau kev tsim nyog tau txais txiaj ntsig

Txawm tias cov txheej txheem zoo tshaj plaws tsis muaj kev soj ntsuam kom tsim nyog {{}}} {1} {ciam teb cov tshev:

 

• Enzyme Stability: Ntxiv cov stabilizers (zoo li calcium chloride) mus rau enzyme da dej. Yog tsis muaj lawv, Ph PHIC kev hloov pauv lossis kub me me yuav ua rau qhov {{1} âase, tawm starce unbroken.
• Alkali Mineutralization: Tom qab da dej alkali, sim siv cov dej yaug pH - yuav tsum yog 6.5-7.5 (nruab nrab). Ib qho seem twg alkali yuav ua paj rwb fibers brittle raws sijhawm.
• Tshuab Ceev: Khaws cov txheej txheem ceev ntawm 20-30m / min. Kev nrawm heev, thiab cov tshuaj tsis muaj sijhawm ua haujlwm; Kev qeeb heev, thiab cov fibers zaum hauv cov da dej hnyav dhau.
• Kev Ntsuas Tus Nqi Ntsuas: Tom qab kev ua tiav, khij cov qauv tsim nyog (cov qauv kev lag luam: loj dua lossis sib npaug rau 85%). Siv cov hmoov txhuv nplej siab uas yooj yim (iodine tov (iodine tov-}}}}}}}}}}}}}}}}}} if if) lossis cov kuab tshuaj rau PVA kom paub meej tias tsis muaj qhov sizing.

 

Rau cov lag luam ua haujlwm nrog polyester - cov ntaub pua nyias (zoo li cov ntaub qhwv ntsej muag)} Nws tus kheej txhawb nqa smoother desizzing. Peb polyester filament thiab staple fibers yog engineered rau cov khoom sib xws thiab lub zog, uas txhais tau tias lawv tuav cov txheej txheem sib tsoo (tsis muaj ntau qhov brittleness lossis fiber ntau tawg paj). Qhov kev sib xws no tseem yuav pab kom peb muaj kev sib txuas lus thaum tab tom cua sov- thov kev tsim nyog rau txoj kab. Yog hais tias koj nyob nraum siourcing polyester fibers rau polyester - pa tsw qab tshuab,
