Backing system hom:
- Polyester knit thaub qab: siab elongation (12-18%), siv hauv cov kis las ncaws pob
- Tsis yog - woven microfiber thaub qab: txhim kho txheej adhesion, siv nyob rau hauv rooj tog upholstery
- Paj rwb sib tov rov qab: siab dua noo noo nqus, qis seem stability
3. Txheeb xyuas OEM / ODM Factories uas ntseeg tau
Cov khoom tsim nyog rau PU tawv yog txheej txheem-raws li cov khoom lag luam-raws li.
