Qee cov khoom ntxiv me me ntawm spandex (elastic fiber, kwv yees li 5% -10%) lossis polyester (polyester fiber ntau, kwv yees li 5% -20%) los txhim kho elasticity lossis durability.
This fabric is called "Derong" because of a patented technology developed by Bayer AG in Germany-a special process treats the surface of acrylic fibers to create a dense, fluffy structure, forming an air layer that enhances warmth and softness.
Qhov sov sov ntawm Derong ntaub feem ntau nyob ntawm nws cov qauv fiber ntau. Acrylic nws tus kheej muaj cov ntaub plaub -zoo li crimp, uas ntxiab ntau cov pa tseem ceeb.
