The common BCF carpet yarn is generally prepared by melt spinning of slices such as PP (polypropylene), PET (polyester), ECDP (modified polyester), PA6 (nylon 6) and the like, but the BCF yarn made of the materials cannot be biodegraded, so that the carpet woven by the carpet yarn causes white pollution to the environment to a great extent after being discarded, and meets the requirement of circular economy.

The Poly Butylene Succinate (PBS) is a polymer with good biodegradability, compared with biodegradable plastics such as polylactic acid and the like, the PBS has relatively low price, excellent mechanical property and good heat resistance, and the PBS-BCF carpet yarn produced by the PBS can meet the biodegradation and has better price advantage than products prepared by the polylactic acid.

The invention has the following characteristics:

1. the raw material used in the invention is PBS (poly butylene succinate).

2. PBS color master batch can be added to make colorful yarns with various styles.

3. The finished product of the primary spinning can be twisted and shaped to be made into multi-style folded PBS-BCF yarn.
