Polyethyleneimine (PEI) Cas 9002-98-6muaj ntau yam kev siv hauv kev lag luam textile thiab yog ib qho khoom siv polymer tseem ceeb. Nws lub hauv paus tseem ceeb yog nws cov cations muaj ntau thiab muaj kev ua haujlwm siab, uas ua rau nws sib xyaw nrog cov fibers, dyes, thiab ntau yam tshuaj reagents, yog li ua rau cov ntaub ntawv muaj cov khoom tshiab lossis txhim kho.

Cov hauv qab no yog cov ntawv thov tseem ceeb thiab cov txiaj ntsig ntawmPEInyob rau hauv kev lag luam textile:

Ⅰ. Kev Xim Xim thiab Kev Luam Ntawv: Txhim Kho Kev Ua Haujlwm Xim thiab Kev Phooj Ywg Ib puag ncig

PEItxhim kho cov teebmeem ntawm kev zas xim thiab luam ntawv ntawm cov ntaub los ntawm kev khi nws cov khoom sib xyaw cationic thiab anionic, thaum txo cov pa phem.

1. Qhov tob ntawm kev zas xim (K/S Value) thiab kev xim ruaj khov:

Cov ntaub uas siv PEI kho xws li paj rwb thiab ntaub plaub tsiaj muaj peev xwm nqus tau xim zoo dua, ua rau cov xim tob dua thiab ci dua. Tib lub sijhawm, ntau yam khoom siv xim ntawm cov ntaub dyed thiab cov ntaub luam tawm (xws li kev tiv thaiv ntxuav thiab kev tiv thaiv kev sib txhuam) tau zoo dua. Piv txwv li, kev tshawb fawb xyoo 2025 tau qhia txog qhov nce feem pua ​​​​​​ntawm cov xim (K / S tus nqi) ntawm cov ntaub uas siv PEI kho.

2. Ua tiav Kev Luam Ntawv Inkjet Uas Tsis Muaj Kev Kho Ua Ntej / Tsis Muaj Kev Ntxuav:

Siv cov hyperbranchedpolyethyleneimine (PEI)Cov kua xim hloov kho (xws li PEI-R218 kua xim), kev luam ntawv inkjet tuaj yeem ua tau ncaj qha rau ntawm cov ntaub tsis tau kho, ua tiav tus nqi kho xim ntau dua 98.7%. Qhov no tshem tawm cov txheej txheem ntxuav ua ntej luam ntawv thiab tom qab luam ntawv, txo qis kev siv tshuaj, dej, thiab zog.

3. Txhawb kev siv cov xim ntuj:

Cov ntaub txhob lo lo ntxhuav uas hloov kho los ntawm PEI tuaj yeem txhim kho qhov nrawm ntawm kev zas xim thiab cov nyhuv zas xim ntawm cov xim ntuj xws li curcumin, txhawb cov txheej txheem zas xim zoo dua rau ib puag ncig.

II. Kev ua tiav zoo: Muab cov ntaub ua "muaj zog heev"

PEIyog ib qho tseem ceeb ntxiv rau hauv kev tsim cov ntaub ua haujlwm, tshwj xeeb tshaj yog ua tau zoo hauv kev tiv thaiv hluav taws.

1. Kev ua haujlwm hluav taws kub zoo

Muaj ntau nitrogen,PEIfeem ntau siv ua cov pa roj carbon lossis roj hauv cov tshuab hluav taws xob intumescent, ua haujlwm synergistically nrog lwm cov phosphorus- thiab silicon-muaj cov nplaim taws retardants.

Cov ntaub paj rwb: Thaum muab sib xyaw nrog cov tshuaj tua hluav taws uas ua los ntawm cov khoom siv bio-based xws li phytic acid (PA), thiab los ntawm kev pauv ion lossis kev sib txuas nrog cov neeg sawv cev crosslinking, cov txheej txheem tiv thaiv hluav taws zoo heev tuaj yeem tsim tau.

2. Cov ntaub viscose

Phosphate-esterified PEI, ua ib yam khoom tiv thaiv hluav taws, tuaj yeem ua rau cov pa oxygen index (LOI) ntawm cov ntaub nce mus txog 28.9%, thiab nws tua nws tus kheej thaum tshem tawm cov nplaim taws.

3. PA56, PAN, thiab lwm yam khoom siv hluavtaws

Los ntawm kev sib txuas lossis txheej txheej los ntawm kev sib dhos tus kheej, cov tes hauj lwm sib txuas tuaj yeem tsim tau, ua tiav kev tiv thaiv hluav taws kub. Piv txwv li, PAN ntaub kho nrog PA / PEI / APTES qhia txog kev nce qib ntawm cov pa oxygen index (LOI) los ntawm 17.4% mus rau 27.5%, thiab qhia txog cov yam ntxwv zoo heev ntawm kev tswj pa luam yeeb.

4. Cov tshuaj tua kab mob thiab cov tshuaj antioxidant

PEI nws tus kheej thiab nws cov hlau sib koom ua ke (xws li PEI-Cu) muaj cov khoom tua kab mob. Cov ntaub paj rwb kho PEI tau pom tias muaj 83.33% ntawm cov kab mob tua kab mob thiab 74.2% cov khoom antioxidant hauv cov ntawv thov triboelectric nanogenerator (T-TENG).

5. Kev Ua Haujlwm Zoo Dua thiab Cov Khoom Tiv Thaiv Hluav Taws Xob:

Kev Tiv Thaiv Hluav Taws Xob: Cov xov paj PEI-modified polyamide (PA) ua rau muaj zog ntxiv rau qhov lo rau ntawm graphene oxide (GO) txheej. Cov xov paj conductive ua rau muaj kev conductivity siab ntawm 4.7 × 10³ S/m tom qab 10,000 khoov, ua tiav qhov kev tiv thaiv hluav taws xob zoo txog li 66.7 dB.

6. Cov Khoom Tiv Thaiv Kev Kub Ntxhov

PEIua rau cov hydrophilicity ntawm cov ntaub, txo cov hluav taws xob static buildup.

7. Cov plaub mos mos tiv thaiv kev felting

Ib qho txheej txheem ua tiav tsis tu ncua siv potassium persulfate (PMS)-PEI hauv ob kauj ruam yog ib qho txheej txheem tsis muaj chlorine thiab zoo rau ib puag ncig.

8. Kev Txhim Kho Qhov Dej thiab Hydrophilicity

PEIkev kho mob ua rau cov dej noo ntawm cov fibers hydrophobic xws li cov ntaub plaub zoo dua, nrog rau qhov hnyav molecular siab dua PEI qhia tau zoo dua.

III. Kev hloov kho qhov chaw: Tsim kom muaj "choj" uas ua haujlwm tau zoo

PEIsiv tau ua "txheej txuas" lossis "tus neeg sawv cev anchoring" rau kev hloov kho fiber tob.

1. Txhim kho lub zog ntawm txheej

Ua ib txheej txheej puag, PEI tuaj yeem txhim kho qhov kev thauj khoom thiab kev sib txuas ntawm cov ntaub ntawv ua haujlwm (xws li MXene (Ti₃C₂Tₓ) thiab graphene oxide (GO)) ntawm qhov chaw fiber.

2. Kev Npaj Cov Khoom Siv Ua Haujlwm

Nws siv tau los npaj cov khoom sib xyaw xws li PEI@PLA aerogels rau cov ntawv thov xws li kev nqus xim.

3. Kev Siv Tshuaj Catalytic

Ua ib tus neeg sawv cev cationizing, nws tuaj yeem siv los kho cov paj rwb fibers, ua rau cov tshuaj catalytic plating ntawm tooj liab sulfide (CuS) rau ntawm lawv qhov chaw, yog li ua tiav conductivity.

Ⅳ. Cov Lus Qhia Luv

Polyethyleneimine (PEI)muaj nqis hauv kev lag luam textile thoob plaws txhua theem, txij li kev zas xim thiab kev ua tiav zoo mus rau kev npaj cov khoom sib xyaw ua ke zoo. Nws tsis yog tsuas yog "txhawb nqa" rau kev txhim kho kev ua tau zoo thiab kev phooj ywg ib puag ncig ntawm cov ntaub ib txwm muaj (paj rwb, plaub mos mos, txhob lo lo ntxhuav), tab sis kuj yog cov khoom siv tseem ceeb rau kev tsim cov ntaub niaj hnub ntse, tiv thaiv, thiab ua tau zoo.

Yuav tsum nco ntsoov tias qhov cuam tshuam ntawm daim ntawv thovPEImuaj feem cuam tshuam nrog nws cov qauv tsim xws li qhov hnyav molecular thiab qib ntawm kev sib cais. Hauv kev siv ua haujlwm, nws yog qhov tsim nyog los xaiv thiab ua kom zoo dua raws li cov txheej txheem tshwj xeeb.
