3 Terms and definitions
There are no terms and definitions that need to be defined in this document.
4 Technical requirements
4.1 Classification and classification regulations
4.1.1 Domestic fine wool and its improved tops are divided into two types. homogeneous tops and heterogeneous tops. Homogeneous tops are based on the average fineness of wool
According to the degree of classification, the heterogeneous wool tops are classified according to the coarse cavity wool rate of the wool. See Table 1 for details.
