Creasing thaum lub sij hawm dyeing yog ib qho kev ntxhov siab tshaj plaws - thiab kim heev - teeb meem hauv kev tsim cov khaub ncaws ncaws pob. Thaum koj ua haujlwm nrog polyester- spandex knit fabrics (xws li 92% polyester / 8% spandex), txawm tias me me nro los yog lub tshuab tsis zoo tuaj yeem ua rau muaj qhov tsis sib xws, cov xim tsis sib xws, thiab cov khoom siv tsis raug.
Tab sis nws tsis tas yuav ua li no.
Hauv phau ntawv qhia dav dav no, peb yuav qhia koj txog vim li cas creasing tshwm sim, yuav ua li cas los tiv thaiv nws ntawm txhua theem, thiab cov tshuab dyeing tshuab ua dab tsi ua rau wrinkle - dawb, siab - cov txiaj ntsig zoo rau activewear, leggings, sports bras, thiab yoga hnav.
Vim li cas Polyester -Spandex Fabric Crease Thaum Dyeing?
Polyester-spandex knits yog elastic heev tab sis thermally rhiab heev. Cov khoom siv spandex (elastane) poob lub zog siab dua 100 degree, thaum polyester xav tau 130-135℃rau kev ua kom cov xim tawg tau zoo nyob rau hauv HTHP (High-Temperature High-Pressure)).
Qhov no ua rau muaj kev tsis sib haum xeeb tseem ceeb:
* Ntau lub tshuab nro → ntaub stretches unevenly → cools rau mus tas li creases
* Ceev ceev cua sov los yog txias → thermal shock → localized shrinkage thiab wrinkles
* Cov ntaub tsis zoo → hlua khi nyob twj ywm compressed ntev dhau → " hlua khi"
Qhov tshwm sim? Qhov tsis txaus ntseeg uas cuam tshuam rau kev zoo nkauj thiab kev ua tau zoo.
Kauj ruam-los ntawm- Kauj ruam: Yuav ua li cas tiv thaiv Creasing hauv Polyester-Spandex Dyeing
1. Xaiv lub tshuab dyeing txoj cai
Tsis yog txhua lub tshuab HTHP dyeing yog sib npaug rau cov ntaub npuag.
| Tshuab Hom | Risk ntawm Creasing | Vim li cas |
| Standard Dav Hlau Dyeing Tshuab | Siab | Siab- dav hlau nrawm rub cov ntaub kom nruj; nruj nreem ntawm spandex |
| Tshwj xeeb HTHP Dyeing Tshuab | Tsawg | Maj mam hla & me jet propulsion; ntaub txav tau yooj yim nrog kev ntxhov siab tsawg |
Kev pom zoo:Siv qhov tsawg- nro soft flow lossis tshwj xeeb HTHP dyeing tshuab zoo li covTH-VK Series, tsim tshwj xeeb rau polyester / nylon -spandex knits.
2. Txhim kho cawv piv txwv: qis dua yog qhov zoo dua (tab sis tsis qis dhau)
* Qhov zoo tshaj plaws cawv piv: 1: 4 rau 1: 6
* Too high (>1:12): Cov dej khib nyiab / tshuaj lom neeg, nce hydrostatic siab → ntau folding
* Tsawg dhau (<1:5): Risk of poor circulation and dry spots → uneven dyeing
Cov tshuab muag muag niaj hnub ua tiav cov xim tsis sib xws ntawm cov cawv tsawg, txo ob qho tib si creasing thiab ib puag ncig.
3. Tswj qhov kub thiab txias Ramp tus nqi Precisely
Spandex degrades sai tshaj 100℃yog rhuab ceev heev.
Qhov zoo tshaj plaws kev xyaum ramp profile:
* 60℃→ 100 degree: 1.5-2.0℃ib feeb
* 100℃→ 130 degree: 1.0-1.5℃ib feeb
* Tuav ntawm 130-135 degree: 30-45 feeb (kom txaus rau cov xim diffusion, tsis ntev li ntawd spandex tsis muaj zog)
Siv lub PLC - tswj qhov system nrog tiag - lub sijhawm saib xyuas kom tsis txhob overshooting.
4. Txias cia maj mam -Tsis txhob quench
Cov cua txias nrawm ua rau thermal contraction, xauv hauv creases.
* Txias ntawm 130℃→ 80℃ntawm 1.5-2.0℃/ min
* Tsuas yog dej cawv tom qab ncav cuag tsawg dua lossis sib npaug li 80 degree
* Tsis txhob poob dej txias
Cov kauj ruam no ib leeg tuaj yeem txo qis kev tsis txaus siab ntau dua 60%.
5. Muab cov txheej txheem soaping kom raug
Tom qab dyeing, unfixed disperse dye zaum ntawm cov ntaub nto. Yog tias tsis tau tshem tawm, nws tsiv mus nyob thaum ziab -tsim pom meej "crease-zoo li" streaks.
* Soaping ntawm 80-90℃nrog tsis yog -ionic detergent
* pH: 5.5-6.5
* Duration: 15–20 feeb
Qhov no ua kom pom tseeb xim tseeb thiab tiv thaiv kev kuaj mob tsis raug.
Tiag -Kev Piv Txwv Ntiaj Teb: Ib Zaj Dab Neeg Kev Ua Si Ntaus Pob
Ib lub tuam txhab ua lag luam activewear hauv Nyab Laj tau hloov los ntawm tus qauv dav hlau dyeing tshuab rau TH-VK Series HTHP dyeing tshuab rau lawv 88% polyester / 12% spandex yoga leggings.
Cov txiaj ntsig tom qab 3 lub hlis:
* Creasing defects txo los ntawm 85%
* Kev siv dej los ntawm 28%
* Cov neeg siv khoom rov qab los ntawm qhov tsis zoo dyeing: ze zero
"Cov ntaub mos muag thiab kev tswj xyuas qhov kub thiab txias ua rau txhua qhov sib txawv," hais tias lawv tus thawj coj tsim khoom. "Tam sim no peb ua tau raws li cov qauv zoo tshaj plaws."
Daim ntawv txheeb zaum kawg: Crease -Dawb Dyeing rau Spandex Blends
