F/R polyester yarn adopts our F/R polyester staple fiber (high intensity and low drawing) as the material and involves spinning and double-twisting. Products available include 6S~ 45S single and double yarn. Features are stable quality and even textile strands (Uster standard) and high intensity.
Quality standard parameters shown in following table:

Name
A+ Level
A Level
Note

Evenness of strands CV (%) ≤
13~16
13~17


Breaking strength of single yarn ≥
29~26
