Dye migration nyob rau hauv ntau- xim spliced khau ntaub ua rau irreversible xim los ntshav mus rau lub teeb meshes thiab laces, ua rau hnyav warranty them rov qab. Raws li kev mob siab rausneaker khoom tsum, WINIW International Co., Limited tshem tawm cov kev ua tsis tiav no los ntawm engineering siab - xim kub- tsau micro suede uas ua lej tswj kom qhuav thiab ntub dej nrawm nrawm ntawm Qib 4-5 (ISO 105-X12).
Thermodynamics ntawm Dye Migration thiab Capillary Action
Dye migration is not merely surface friction transfer; it is the thermodynamic sublimation and penetration of disperse dye molecules under high heat or humidity. During automated EVA outsole cementing (>80 degree) los yog nyob rau hauv lub siab noo noo load ntawm tib neeg perspiration, unfixed dye molecules undergo hnyav Brownian suab.
Yog tiasdye migration khau tawvtsis muaj qhov sib sib zog nqus molecular fixation thaum lub sij hawm coagulation, cov dawb molecules migrate ntawm capillary kev txiav txim ncaj qha mus rau hauv lub teeb nyob ib sab- xim substrates. Siv cov tshuaj tiv thaiv passive los tiv thaiv- cov tshuaj tiv thaiv kev tsiv teb tsaws los daws qhov teeb meem no nquag ua rau lub micro-fibrous nap thiab degrades tactile kev sib txhuam. Kev ruaj ntseg xim tiag tiag yuav tsum tso cov xim ncaj qha rau hauv 3D hiav txwv -kob polyethylene terephthalate (PET) matrix.

Xa koj lub hom phiaj CIELAB xim tsis muaj rau WINIW International Co., Limited, thiab thov peb cov ntaub ntawv pov thawj Khaub ncawslab-dip thiab thib peb- tog SGS cov ntaub ntawv soj ntsuam hnub no.
Siab -Kev Kho Mob Kub thiab ISO 105 Metrics
Hauv qhov tshwj xeeb nocolorfast micro suede rooj plaub, peb cov kws ua haujlwm R&D tau hloov kho cov txheej txheem tshuaj lom neeg - txuas raws tu qauv. Peb xa 130℃siab -siab vat dyeing integrated nrog eco-tus phooj ywg cationic fixing agents. Cov tshuaj tiv thaiv cov tshuaj tiv thaiv no tsim cov macromolecular complexes insoluble, lub cev kaw cov dye molecules hauv cov tub ntxhais network ntawm microfiber.

Qhov kev sib sib zog nqus fixation no induces xoom mechanical degradation. Lub substrate tuav ib tug nruam ISO 2411 peeling zog ntawm ntau dua los yog sib npaug rau 30 N / 3cm thiab ib tug EN ISO 3377-2 kua muag zog ntawm Greater los yog sib npaug rau 60 N, yooj yim ciaj sia siab - nro automated CNC txiav. Tsis tas li ntawd, tag nrho cov dyeing thiab coagulation architecture yog 100% DMF-dawb, sau npe 0 mg / kg ntawm cov hlau hnyav seem thiab dawb formaldehyde kom dhau ZDHC Qib 3 thiab EU REACH Annex XVII tshawb xyuas.

Cov lus nug nquag nug (FAQ)
Q: Vim li cas dye migration khau tawv tseem ceeb rau cov khau ntaub spliced?
A: Unfixed dye molecules migrate ntawm capillary nkaus nyob rau hauv high kub (thaum lub sij hawm ib leeg cementing) los yog hws, mus tas li staining cov ntaub ntawv. Kev qhia cov substrates nrog Qib 4-5 ntub dej nrawm nrawm lub cev thaiv qhov kev tsiv teb tsaws no, tshem tawm cov nqi muag khoom muag rov qab los.
Q: Yuav ua li cas cov khoom siv khau ntaub ua kom tiav colorfast micro suede?
A: WINIW siv 130℃siab -siab dyeing ua ke nrog cationic fixing agents. Qhov no tsim cov macromolecular complexes insoluble nyob rau hauv lub hiav txwv 3D -kob PET matrix, ua lej lav qhov qhab nia qib 4-5 raws li ISO 105-X12 cov txheej txheem qhuav thiab ntub dej.
Q: Cov ntaub ntawv colourfast micro suede puas ua raws li kev txwv tshuaj?
A: Yog. Tag nrho cov txheej txheem dyeing thiab aqueous coagulation yog 100% DMF-dawb. Nws muaj xoom txwv tsis pub azo dyes lossis cov hlau hnyav, sau npe 0 mg / kg ntawm VOCs kom ua raws li EU REACH Annex XVII thiab ZDHC Qib 3 cov qauv.
