细毛也叫细毛。它是长毛兔皮毛中最柔软、最纤巧的毛纤维，呈波浪状和弧形，长5 ~ 12厘米，细度7 ~ 30微米，平均14.99微米。绒毛兔的毛含量一般占毛总量的80% ~ 93%。兔毛纤维的质量在很大程度上取决于细毛纤维的数量和质量。
Fine hair is also called fine hair. It is the softest and most delicate hair fiber in the fur of long haired rabbit. It is wavy and arc-shaped, 5-12 cm long, 7-30 μ m in fineness, with an average of 14.99 μ M. The hair content of the villous rabbit generally accounts for 80% - 93% of the total hair. The quality of rabbit hair fiber depends on the quantity and quality of fine hair fiber to a great extent.
The scales are generally arranged in a circular overlapping pattern, and the ends of scales are free. The medulla is arranged longitudinally by a layer of polygonal cells, so the cortex is relatively thick.
2、 Dichotomous hair
分叉指的是一根头发纤维上有两种类型的纤维。纤维上半部分呈扁平状，无卷曲，髓层发达，有粗毛的特点，纤维下半部分较薄，卷曲不规则。它仅由单列髓细胞组成，具有细毛的特征。两种类型的毛细度为15-30微米，平均为23.11微米。头发中的含量较少，一般只占1% ~ 5%。由于两种羊毛的直径不同，容易断裂，毛纺值低。
Branching refers to two types of fibers on one hair fiber. The upper part of the fiber is flat, without curl, with developed pith layer and coarse hair. The lower part of the fiber is thin and irregular curl. It is only composed of single row pith cells and has the characteristics of fine hair. The two types of wool have a fineness of 15-30 microns, with an average of 23.11 microns. The content of hair is less, generally only 1% - 5%. Due to the different diameters of the two kinds of wool, it is easy to break and the wool spinning value is low.
粗糙的毛发也被称为枪毛或针毛。是兔毛中最长最厚的纤维，直、硬、光滑、不弯曲，长度10 ~ 17厘米，细度31 ~ 120微米，平均为47.77微米，一般只占毛总量的5% ~ 10%，粗毛型兔毛可达18%以上。粗糙的毛发抗磨性强，具有保护绒毛、防止毛毡的作用。根据羊毛行业和兔毛市场的需求，粗毛率已成为长毛兔生产类型分类的重要性能指标。
Rough hair is also known as gun hair or needle hair. It is the longest and thickest fiber in rabbit hair, straight, hard, smooth and unbending, with a length of 10-17cm, a fineness of 31-120um, an average of 47.77um, generally accounting for only 5-10% of the total amount of hair, and coarse rabbit hair can reach more than 18%. Rough hair has a strong anti-wear property, which can protect fluff and prevent felt. According to the demand of wool industry and rabbit hair market, the coarse wool rate has become an important performance index of production type classification of long wool rabbit.
