Dyeing stretch fabrics-tshwj xeeb tshaj yog polyester-spandex lossis nylon-spandex knits- yog qhov tsis zoo. Cov khoom siv ua haujlwm siab no muaj zog niaj hnub no cov khaub ncaws ncaws pob, yoga leggings, thiab compression hnav, tab sis lawv rhiab heev rau cov cua sov, nro, thiab cov tshuaj ua rau lawv yooj yim rau crease, poob elasticity, tsis sib xws dyeing, thiab ceev ceev tsis zoo.
Txawm li cas los xij nrog cov txheej txheem tswj kom raug, koj tuaj yeem ua tiav cov txiaj ntsig zoo, ruaj khov, thiab tsis muaj qhov tsis zoo-txhua lub sijhawm.
Hauv phau ntawv qhia no, peb muab cov kauj ruam-los ntawm- kauj ruam, daim ntawv tshuaj xyuas ua tiav rau dyeing stretch fabrics hauv HTHP (High-Tsuas Kub-Txias) cov cav tov, txij li ua ntej- kev kho mob mus rau zaum kawg soaping. Sau nws, qhia rau koj pab neeg, thiab siv nws ua koj tus qauv tsim txhua hnub.
Vim li cas Daim Ntawv Teev Npe no tseem ceeb
Stretch fabrics muab cov hluavtaws fibers (polyester / nylon) nrog elastane (spandex) -ib qho polymer uas:
* Degrades saum 100-110℃yog tias nthuav tawm ntev dhau
* Poob rov qab los ntawm kev ntxhov siab kho tshuab
* Reacts tsis zoo rau hnyav pH lossis hloov kub ceev
Ib qho yuam kev hauv lub voj voog dyeing tuaj yeem rhuav tshem tag nrho cov khoom. Daim ntawv txheeb xyuas no tshem tawm kev kwv yees.
Qhov kawg dyeing Checklist rau Stretch Fabrics (HTHP txheej txheem)
Kauj Ruam 1: Ua ntej-Kev Kho Mob - Huv, Tab sis Yooj Yim
Lub hom phiaj: Tshem tawm cov roj, tig tiav, thiab impurities yam tsis muaj kev puas tsuaj spandex.
✅ Scour ntawm 80-85℃(tsis siab tshaj 90 degree)
✅ Siv cov tshuaj alkaline me me (pH tsawg dua lossis sib npaug li 9.5)
✅ Zam tsis txhob muaj cov tshuaj oxidizers los yog cov tshuaj chlorine - raws li cov neeg ua haujlwm
✅ Yaug kom huv si kom txog thaum dej ntshiab
❌ Tsis txhob mercerize -paj rwb-tsuas yog txheej txheem!
💡 Tswv yim: Kuaj ntaub yuag poob tom qab scouring -yuav tsum yog<2%. Higher = fiber damage.
Kauj Ruam 2: Kev xaiv tshuab - Kev Nyuaj Siab Tsis Muaj -Tshaj tawm
Tsis yog txhua lub tshuab HTHP tsim nyog.
✅ Siv cov dej ntws los yog qis qis qis (piv txwv li, TH-VK Series)
✅ Paub meej tias lub tshuab muaj cov raj xa mus zoo (tsis muaj qhov khoov ntse)
✅ Xyuas kom cov hlua ntaub txav tau yooj yim yam tsis muaj kev rub tawm
❌ Zam tsis txhob muaj tus qauv siab - lub tshuab dav hlau siab - lawv ncab thiab crease spandex.
Kauj Ruam 3: Dye & Chemical Teeb
Fiber- cov qauv tshwj xeeb yog qhov tseem ceeb.
| Hom ntaub | Dye Class | Cov pab cuam tseem ceeb |
| Polyester -Spandex | Disperse dyes | Dispersing agent, leveling agent, acetic acid (pH 4.5-5.5) |
| Nylon{0}}Spandex | Acid dyes | Qib tus neeg sawv cev, pH tsis kam (pH 4-6) |
✅ Ib txwm siv spandex- muaj kev nyab xeeb dispersants (tsis yog-ionic)
✅ Tsis txhob muaj cov cab cab -lawv ua rau cov elastane tsis muaj zog thiab txo lub teeb nrawm
✅ Ua ntej- faib cov xim kom zoo los tiv thaiv kev sib sau
Kauj Ruam 4: Cua sov Profile - qeeb & khov kho yeej
Ramp tus nqi ua los yog tawg spandex kev ncaj ncees.
60℃→ 100 degree: 1.5-2.0℃ib feeb
100℃→ 130℃(rau polyester): 1.0-1.5℃ib feeb
Lub sijhawm tuav: 30-45 feeb ntawm 130-135℃(polyester) lossis 98-100℃(nylon)
✅ Saib xyuas lub siab: Ua kom ruaj khov ntawm 2.5–3.5 bar
⚠️ Ceeb Toom: Cua sov sai dua=thermal shock=mus tas li creases.
Kauj Ruam 5: Txias - Kauj Ruam Tshaj Tawm
Ceev ceev txias xauv hauv wrinkles.
✅ Txias maj mam: 130℃→ 80℃ntawm 1.5-2.0℃/ min
✅ Tsis txhob tso dej kom tsawg dua lossis sib npaug li 80 degree
✅ Tsis txhob txias - dej quenching
Cov kauj ruam no ib leeg tiv thaiv 70% ntawm post-dyeing creasing tsis txaus siab.
Kauj Ruam 6: Soaping - Tsis txhob hla nws!
Unfixed dye rau ntawm qhov chaw ua rau tsis zoo ntxuav sai thiab "tsis tseeb creasing."
✅ Soaping kub: 80-90 degree
✅ Duration: 15–20 minutes
✅ Siv tsis yog- ionic xab npum (spandex- tau tshaj)
✅ pH: 5.5-6.5
✅ Ua raws li nrog sov → txias yaug
✨ Pro tip: Ua ib qho kev kuaj crocking tom qab soaping -yog tias rub nrawm<4, repeat soaping.
Kauj Ruam 7: Kev soj ntsuam zaum kawg & Kev Tswj Xyuas Zoo
Ua ntej tsiv mus rau qhov kawg:
✅ Tshawb nrhiav:
Creases los yog hlua khi
Xim variation (siv D65 teeb pom kev zoo)
Poob elasticity (stretch- rov qab kuaj)
pH ntawm ntaub (yuav tsum yog 5.5-7.0)
✅ Sau cov ntaub ntawv batch: kub nkhaus, cawv piv, tshuaj ntau npaum
Qhov cuam tshuam tiag tiag: Mill's Transformation
Ib tus neeg muag khoom ntawm Turkish activewear txo tus nqi tsis zoo los ntawm 82% tom qab siv daim ntawv txheeb xyuas no nrog TH-VK Series HTHP soft flow machine. Lawv cov kev hloov pauv tseem ceeb:
* Hloov los ntawm dav hlau mus rau cov dej ntws
* Kev tswj kev ua kom txias / txias
* Ntxiv yuav tsum tau soaping
Qhov tshwm sim: Zero cov neeg siv khoom tsis lees paub ntawm cov kab yoga hwm rau 6 lub hlis ncaj.
