Vim li cas cov ultrasonic lace tshuab wrinkle cov ntaub thaum vuam nws?

1. Mismatch hauv cov khoom siv khoom
Vim li cas: Thaum cov ntaub yog cov ntaub nyias nyias, xws li cov ntaub qhwv koob, txheej hluavtaws tau yooj yim tuaj yeem yooj yim rau cov fiber ntau shrinkage lossis kev hloov chaw.
Daws:
Xaiv cov ntaub tsim rau ultrasonic vuam, xws li thermoplastic fibers zoo li polyester thiab nylon .
Pre tshav kub teeb tsa elastic ntaub los txhawb nqa nws nrog cov ntaub qhwv .

2. Tsis ncaj lossis ntau dhau los
Vim li cas:
Ntau dhau ntawm lub taub hau vuam (pwm) ua rau deformation los ntawm muab cov ntaub qhwv cov ntaub .
Tsis sib haum siab muab faib (xws li tsis parallel vuam taub hau thiab hauv qab pob) .
Daws:
Kho lub siab rau qib me me (ntsuas hluav taws xob vuam lub zog thiab cov ntaub qhwv ntsej muag) .
Txheeb xyuas parallelism ntawm lub taub hau vuam thiab hauv qab pwm kom ntseeg tau yooj yim .

3. Tsis raug cai courration ntau dua lossis lub zog
Vim li cas:
Lub zog ntau dhau: overheating ua rau ntaub kom shrink los yog yaj ntau dhau .
Tsis txaus zog: lub vuam tsis ruaj thiab yuav tsum tau ua dua tshiab, uas ua exacerbates wrinkling .
Daws:
Kho cov ultrasonic amplitude (feem ntau 20-35 cmz) thiab vuam lub sijhawm ({1} .
Xeem tsis (lub zog, siab, lub sijhawm) ntawm tus qauv ua ntej .
