I often see the comparison between polypropylene BCF yarn and polyester carpet yarn, so which one is more cost-effective?

In terms of feel, polyester is better than polypropylene carpet silk, but polypropylene has better abrasion resistance than polyester. Polypropylene BCF yarn is now used more on carpets because of its light texture, low price and friction resistance. Management, especially compared to polyester carpets. The key to the best carpet is to take care of it.

Polypropylene BCF yarn and polyester carpet yarn both have their advantages and disadvantages, so we can't generalize them. The key is to look at the requirements of oneself.
