1. Lub txheej txheej sab nraud yog spunbonded nrog ntsiabteeb, thiab txheej sab hauv yog yaj nrog superfine fiber.
2. Tsawg gram hnyav, siab zog, siab elongation, siab permeability, muaj zog dej tsis kam.
3. Cov khoom lag luam muaj cov qauv zoo thiab tsis yooj yim opacity.
4. Lub spunbonded txheej yog tsim ntawm cov ntsiab lus txuas ntxiv nrog zoo rhuav lub zog thiab elongation.
5. Nws muaj qhov thaiv zoo ntawm dej, kab mob thiab hmoov av.
6. Nws muaj dej siab tiv taus thiab huab cua zoo permeability.
7. Yaj tshuab txheej yog tsim los ntawm cov nplaim hluav taws xob tsis tu ncua. 9. tuaj yeem tsim cov xim sib txawv.
