Polyester yog cov khoom siv hluavtaws uas tau siv dav hauv kev lag luam zam. Nws yog nrov vim nws durability, versatility, thiab yooj yim-care zog. Polyester muaj lub siab melting point, uas ua rau nws nyuaj rau dyeing ntaub. Txhawm rau kov yeej qhov kev sib tw no, cov pab cuam yog siv thaum dyeing polyester. Auxiliaries yog cov tshuaj uas txhim kho cov txheej txheem dyeing, txhim khu xim rendering, thiab txhim kho cov ntaub.
Nov yog qee qhov kev pabcuam siv hauv polyester dyeing:
1. Dispersing agents: Polyester yog hydrophobic, uas ua rau nws nyuaj rau dissolve dyes nyob rau hauv dej. Dispersing agents tiv thaiv dye pigments los ntawm kev tsim agglomerates, thiab lawv pab dyes kom disperse homogeneously rau hauv polyester fibers rau txawm coloring.
2. Leveling agents: Polyester fibers muaj crystallinity tsawg thiab tsis muaj reactive qhov chaw rau dye molecules mus txuas. Leveling agents pab faib cov xim sib npaug thoob plaws hauv cov ntaub, ua kom cov dyeing zoo ib yam thiab xim sib xws.
3. Sequestering agents: Sequestrants yog siv los tshem tawm cov hlau ions xws li hlau, tooj liab, thiab manganese, uas yuav ua rau staining, discoloration, los yog unevenness nyob rau hauv cov xim. Cov neeg ua haujlwm no pab txhim kho qhov zoo ntawm cov xim thiab txhim kho xim ceev.
4. Cov khoom ntub dej: Polyester fibers muaj qhov tsis muaj polar nto thiab yuav tsum muaj tus neeg sawv cev ntub dej los txhim kho kev nqus dej thiab txhim kho cov xim diffusion rau hauv cov fibers. Cov tshuaj ntub dej yog qhov tseem ceeb los xyuas kom meej tias cov ntaub nqus cov xim sib npaug.
5. Antifoaming agents: Thaum lub sij hawm dyeing txheej txheem, huab cua npuas tuaj yeem tsim thiab ua rau cov xim tsis sib xws thiab ua raws. Antifoaming cov neeg ua haujlwm pab tiv thaiv kev tsim ua npuas ncauj, kom ntseeg tau tias cov ntaub nqus cov xim tsis sib xws, ua rau muaj xim zoo ib yam.
6. Catalyzing agents: Polyester yuav tsum tau kub kub rau dyeing, thiab catalyzing cov neeg ua hauj lwm pab kom zoo dye nkag mus, luv dyeing lub sij hawm, thiab qis dyeing kub, uas txuag lub zog thiab tsis txhob muaj teeb meem xws li ntaub puas, xim poob, los yog shrinkage.
Hauv kev xaus, cov koom haum pab ua lub luag haujlwm tseem ceeb hauv kev kov yeej cov teeb meem ntawm dyeing polyester. Los ntawm kev siv cov auxiliaries no, peb tuaj yeem ua tiav cov xim zoo ib yam, muaj zog, thiab kav ntev thaum txhim kho cov ntaub ua haujlwm. Kev siv cov auxiliaries yog qhov tseem ceeb rau kev txhim kho qhov zoo thiab tus nqi ntawm polyester ntaub thiab ua tau raws li qhov xav tau ntawm kev lag luam zam.
