Cationic polyester

Cationic dyeable polyester, tshuaj lub npe: polybutylene terephthalate (elastic polyester); Lub npe Askiv: cationic dyed polyester; Cov ntawv luv: PBT, kuj siv rau hauv lub Hoobkas CD. Cationic polyester belongs rau denatured / hloov polyester thiab tuaj yeem dyed nrog cationic dyes ntawm 110 C.

Kev hloov kho ntawm Cationic Polyester Fiber

Cationic dyeable polyester yog hloov los ntawm copolymerization ntawm polyester dyeable modifier, xws li dimethyl isophthalate-5-sodium sulfonate (feem ntau hu ua trimer, lus Askiv SIPM) nrog polyester. Sulfonic acid pawg tau nkag mus rau hauv cov hlua polyester molecular tom qab copolymerization, uas tuaj yeem dyed nrog cationic dyes. Cov ntaub dyed muaj cov xim ci, siab dye exhaustion tus nqi, zoo heev txo qhov paug ntawm luam ntawv thiab dyeing dej khib nyiab, thiab copolyester. Chips tseem tuaj yeem ua rau muaj kev tiv thaiv zoo li qub, pilling thiab nqus dej noo, uas yog ib txoj hauv kev tseem ceeb los txhim kho cov khoom dyeing ntawm polyester fibers hauv xyoo tas los no. Kev sib xyaw ua ke ntawm 4 cationic dyeable polyesters uas muaj sulfonated isophthalate units thiab 1 block copolymer ntawm ethylene glycol / polyethylene glycol / sulfonated sodium isophthalate / terephthalic acid los ntawm Yonigika Tuam Txhab ntawm Nyiv tuaj yeem tsim cov fibers ultrafine nrog siab dyeing qhov tob. Cationic activator thiab ib qho me me ntawm kev hloov pauv tau ntxiv rau BHET ua ntej lossis thaum lub sijhawm tig. Hydroxyethyl Acids) Copolymerization. Lub spinnability ntawm cov copolymer yog txhim kho tom qab lawv tau ua nyob rau hauv random linear copolymer. Hloov polyester tsis tsuas yog tuaj yeem dyed nrog cationic dyes, tab sis kuj muaj cov cuab yeej los tiv thaiv pilling thiab txhim kho wrinkle rov qab.

Cationic Polyester Properties

Lub melting point ntawm cationic polyester npaj los ntawm SIPM copolymerization yog qis dua li ntawm cov polyester zoo tib yam, thiab nws cov crystallinity yog qis dua li ntawm cov polyester zoo tib yam, uas ua rau cov xim molecules permeable yooj yim, ua rau cov fibers yooj yim rau zas, txhim kho qhov nqus thiab txhim kho hygroscopicity. .

Qhov hnyav molecular, crystallinity thiab lub zog ntawm cationic polyester fibers yog qis dua li cov polyester fibers zoo tib yam, thiab pilling kuj ntawm cationic polyester fabrics yog zoo dua li ntawm cov polyester fibers. Cov Young's modulus ntawm cationic polyester yog 10% ~ 30% qis dua li ntawm cov polyester zoo tib yam, yog li cov ntaub ntawm cationic polyester kuj softer dua li ntawm cov polyester zoo tib yam.

Tsis tas li ntawd, alkaline hydrolysis tus nqi ntawm cationic polyester yog sai dua li ntawm cov polyester zoo tib yam. Yog li ntawd, alkali txo tus nqi ntawm cationic polyester ntaub yog ntau dua li ntawm cov ntaub polyester zoo tib yam ntawm qhov kub thiab txias.

Cationic polyester tsis tsuas yog lav cationic dyeability, tab sis kuj nce micropore ntawm cov fibers, txhim kho tus nqi dyeing, permeability thiab noo noo nqus ntawm cov fibers, yog li ntxiv adapting rau silking simulation ntawm polyester fibers; los ntawm silking simulation, cov ntaub yuav mos, breathable, xis, antistatic, dyeable ntawm chav tsev kub thiab atmospheric siab; los ntawm kev hloov kho cationic, ntau txoj haujlwm wool imitation tuaj yeem ua rau cov ntaub mos, antistatic thiab dyeable. Anti-pilling, co-dyeing nrog ntaub plaub ntawm chav tsev kub thiab siab.

Npuag ua los ntawm cationic modified fibers muaj cov yam ntxwv nram qab no thaum dyed nrog cationic dyes:

1. Lub suab ci, zoo sib sib zog nqus dyeing;

2. Siab hygroscopicity

3. Zoo lub teeb ceev ceev thiab fading ceev;

4. Lub compatibility ntawm dyes yog zoo thaum dyeing nrog cov xim ua ke.

5. Nyob rau hauv qhov kub kub dyeing da dej, lub stability yog zoo.

6. Nws muaj cov kab mob me me rau lwm cov fibers, nrog rau cov polyester fibers zoo tib yam.

7. Tus nqi diffusion rau cov fibers yog ceev thiab tsis muaj lub nplhaib dyeing tshwm sim.

8. Thaum tus nqi pH hloov pauv hauv cov dyeing da dej, cov dyeing muaj kev ruaj ntseg siab.

Cationic hloov polyester filament thiab polyester filament tsis tuaj yeem paub qhov txawv, yog tias koj xav paub qhov txawv, koj tuaj yeem siv txoj kev dyeing xwb! Cationic raw khoom feem ntau yog tsaus!

Cov duab hauv qab no qhia qhov sib txawv ntawm cations thiab glossy polyester fibers. Qhov tseeb, nws yog qhov nyuaj heev kom paub qhov txawv ntawm qhov muag liab qab.

Cationic ntaub

Cationic fabrics yog cationic yarns nrog kev kho tshwj xeeb, xws li cationic polyester xov paj los yog cationic nylon xov.

Ib qho ntawm cov yam ntxwv ntawm cationic fabrics yog cov nyhuv ob xim, uas tuaj yeem siv los hloov qee cov xim-woven ob-xim ntaub los txo tus nqi ntawm cov ntaub. Qhov no yog tus yam ntxwv ntawm cationic fabrics, tab sis nws kuj txwv nws cov yam ntxwv. Nyob rau hauv lub ntsej muag ntawm ntau xim ntaub, cationic fabrics tsuas yog hloov los ntawm cationic fabrics.

Cationic fabrics muaj cov xim ci thiab tsim nyog siv los ua cov fibers, tab sis lawv muaj cov xim tsis zoo rau lub teeb thiab ntxuav ntawm ntuj cellulose thiab protein fabrics.

Kev hnav tsis kam ntawm cationic fabrics kuj zoo heev. Tom qab ntxiv qee cov khoom siv fiber ntau xws li polyester thiab spandex, lub zog thiab elasticity ntawm cationic fabrics siab dua, thiab hnav tsis kam ntawm cationic fabrics yog thib ob tsuas yog nylon.

Cationic fabrics muaj qee yam tshuaj lom neeg, xws li corrosion kuj, alkali tsis kam, tshuaj dawb, oxidants, hydrocarbons, ketones, roj av khoom thiab inorganic acids, nrog rau qee lub cev muaj zog, xws li ultraviolet tsis kam.
