The wool loss after the wool is broken. In view of this situation, Ms. Liu suggested that customers can use horsehair to produce. First of all, horsehair has better toughness, not easy to break. Secondly, the performance of horsehair meets the requirements of revolving door draught brush strip; Many customers of the revolving door in the industry have changed from the wool to the horsehair, which has received an unusual effect. Later, Miss Liu sent a sample of horsehair door draught brush strip to Mr. Bi.
