Cationic polyester

Cationic dyeable polyester, zita remakemikari: polybutylene terephthalate (elastic polyester); Zita reChirungu: cationic dyed polyester; chidimbu: PBT, inoshandiswawo mufekitari CD. Cationic polyester ndeye denatured/modified polyester uye inogona kudhayiwa ne cationic dhayi pa 110 C.

Kugadziriswa kweCationic Polyester Fiber

Cationic dyeable polyester inogadziridzwa necopolymerization yepolyester dyeable modifier, senge dimethyl isophthalate-5-sodium sulfonate (inowanzozivikanwa se trimer, Chirungu chidimbu SIPM) ine polyester. Sulfonic acid boka rinounzwa mu polyester molecular cheni mushure mecopolymerization, iyo inogona kudhayiwa ne cationic dhayi. Iro jira rakadhayiwa rine ruvara rwakajeka, dhayi yakakwira kupera simba, ichideredza zvakanyanya kubuda kwekudhinda uye kudhaya tsvina yemvura, uye copolyester. Machipisi anogona zvakare kuwedzera antistatic, pilling uye mwando absorption zvivakwa, inova imwe yenzira huru yekuvandudza dhayi zvimiro zvepolyester fiber mumakore achangopfuura. Musanganiswa we 4 cationic dyeable polyesters ane sulfonated isophthalate units uye 1 block copolymer ye ethylene glycol/polyethylene glycol/sulfonated sodium isophthalate/terephthalic acid neYonigika Kambani yekuJapan inogona kugadzira ultrafine faibha dzine kudzika kwekudayi kwakadzika. Cationic activator uye zvishoma zvekugadzirisa zvinowedzerwa kuBHET zvisati zvaitika kana panguva yekutenderera. Hydroxyethyl Acids) Copolymerization. Iko kukwenenzverwa kwemacopolymers kunovandudzwa mushure mekunge aitwa asina kujairika linear copolymers. Iyo polyester yakagadziridzwa kwete chete inogona kudhayiwa ne cationic dhayi, asiwo ine anti-pilling midziyo uye yakagadziridzwa wrinkle kupora.

Cationic Polyester Properties

Iyo yekunyunguduka ye cationic polyester yakagadzirwa neSIPM copolymerization yakaderera pane iyo yakajairwa polyester, uye crystallinity yayo yakadzikira pane yakajairwa polyester, iyo inoita kuti mamorekuru edhayi apinde nyore, inoita kuti mafibers ave nyore kudhaya, inovandudza kunyura uye inovandudza hygroscopicity. .

Huremu hwemamorekuru, crystallinity uye kusimba kwe cationic polyester fibers zvakaderera pane izvo zvakajairika polyester fiber, uye kuramba kwepilling kwemachira e cationic polyester kuri nani pane kuya kweakajairika polyester fiber. Iyo Young's modulus ye cationic polyester ine 10% ~ 30% yakaderera pane iyo yakajairika polyester, saka jira re cationic polyester zvakare rakapfava kupfuura iro reyakajairika polyester.

Pamusoro pezvo, iyo alkaline hydrolysis mwero we cationic polyester inokurumidza kupfuura yeyakajairika polyester. Naizvozvo, iyo alkali yekudzikisa mwero we cationic polyester machira akakwira zvakanyanya kupfuura iwo akajairwa polyester jira patembiricha imwe chete.

Cationic polyester haingovimbisi cationic dyeability, asiwo inowedzera micropore yefibers, inovandudza dhayi rate, permeability uye kunyorova kwehunyoro hwefiber, nekudaro ichienderera mberi ichichinjika kune silking simulation yepolyester fibers; kuburikidza nesilking simulation, jira rinogona kuva rakapfava, rinofema, rakasununguka, antistatic, rinodhayiwa pane tembiricha yekamuri uye kumanikidzwa kwemhepo; kuburikidza ne cationic modification, iyo yakawanda-inoshanda mvere yekutevedzera inogona kuita kuti jira rakapfava, risingatarisike uye rinodhayiwa. Anti-pilling, co-dhayi nemvere dzemakwai patembiricha yekamuri uye kumanikidza.

Micheka yakagadzirwa ne cationic modified fibers ine zvinotevera maitiro kana akadhayiwa ne cationic dhayi:

1. Inzwi rakajeka, kudhaya kwakanaka kwakadzika;

2. High hygroscopicity

3. Kutsanya kwakanaka kwechiedza uye kupera kwekukurumidza;

4. Kuenderana kwedhayi kwakanaka kana uchidhaya nemusanganiswa wemavara.

5. In high tembiricha dyeing bhati, kugadzikana kwakanaka.

6. Iine kusvibiswa kudiki kune mamwe mafiber, kusanganisira akajairika polyester fibers.

7. The diffusion rate kune fibers inokurumidza uye hapana ring dyeing phenomenon.

8. Apo pH kukosha kunoshanduka mubhati rekudhaya, dhayi ine kugadzikana kwakanyanya.

Cation yakagadziridzwa polyester filament uye polyester filament haigone kusiyaniswa, kana iwe uchida kusiyanisa, unogona chete kushandisa nzira yekudhaya! Cationic mbishi zvinhu zvinowanzo sviba!

Mufananidzo unotevera unoratidza mutsauko uripo pakati pemakesheni uye glossy polyester fibers. Kutaura zvazviri, zvakaoma zvikuru kusiyanisa neziso rakashama.

Cationic jira

Machira eCationic machira e cationic ane kurapwa kwakakosha, senge cationic polyester yarn kana kuti cationic shinda yenaironi.

Humwe hunhu hwemachira e cationic ndeye maviri-mavara maitiro, ayo anogona kushandiswa kutsiva mamwe mavara-akarukwa maviri-mavara machira kuderedza mutengo wemachira. Ichi ndicho chimiro chemicheka ye cationic, asi inogadzirisawo maitiro ayo. Pamberi pemicheka yakawanda-mavara, machira e cationic anogona kungotsiviwa nemicheka ye cationic.

Machira eCationic ane mavara akajeka uye akakodzera kushandiswa semafibhi ekugadzira, asi ane hurombo husina kunaka kwemavara kuchiedza uye kugezwa kwechisikigo cellulose nemachira eprotein.

Iko kupfeka kupikisa kwemachira e cationic zvakare kwakanaka kwazvo. Mushure mekuwedzera mamwe mafibhi ekugadzira akadai sepolyester uye spandex, kusimba uye elasticity yemachira e cationic akakwira, uye kusagadzika kwemachira e cationic ndeyechipiri kune naironi.

Machira eCationic ane mamwe makemikari zvinhu, senge corrosion resistance, alkali resistance, bleaching resistance, oxidants, hydrocarbons, ketones, petroleum products uye inorganic acids, pamwe nezvimwe zvinhu zvemuviri, senge ultraviolet resistance.
