兔毛纤维按其粗细、长短、弯曲形态和髓层的发达程度，可将兔毛纤维大体分为细毛(绒毛)、两型毛和粗毛(枪毛)3种类型。

Rabbit hair fibers can be roughly divided into three types: fine hair (villi), two types of hair and coarse hair (gun hair), according to their thickness, length, curved shape and the degree of development of medullary layer.

一、细毛

I. Fine Hair

细毛又称绒毛。是长毛兔被毛中更柔软纤细的毛纤维，呈波浪形弯曲，长5～12厘米，细度为7～30微米，平均为14.99微米，绒毛型兔的绒毛含量一般占被毛总量的80％～93％。绒毛型长毛兔的毛纤维质量，在很大程度上取决于细毛纤维的数量和质量，细毛在毛纺工业中适用于加工精纺产品如高档纯毛内衣、内裤和呢料等。

Fine hair is also called villus. It is the softest and slender wool fiber in the coat of long-haired rabbits. It is wavy, 5-12 cm long and 7-30 micron in fineness, averaging 14.99 micron. The wool content of the wool type rabbits generally accounts for 80-93% of the total coat. The wool quality of wool rabbit depends largely on the quantity and quality of fine wool fibers. Fine wool is suitable for processing worsted products such as high-grade pure wool underwear, underwear and high-grade fabrics in wool spinning industry.

鳞片一般呈环状复叠式排列，鳞片端呈游离状。髓层由单层多角细胞点状纵向排列，因此，皮质层相对较厚。

The scales are generally arranged in a circular cascade, and the scales end is free. The medullary layer is arranged longitudinally and punctually by monolayer polygonal cells, so the cortex is relatively thick.

二、两型毛

Type II and Type II Hair

两型毛是指单根毛纤维上有两种纤维类型。纤维的上半段平直无卷曲，髓质层发达，具有粗毛特征，纤维的下半段则较细，有不规则的卷曲，只由单排髓细胞组成，具有细毛特征。两型毛细度为15-30微米，平均23.11微米。在被毛中含量较少，一般仅占1％～5％。两型毛因粗细交接处直径相差很大，极易断裂，毛纺价值较低。

Two types of hair refer to two types of fibers on a single hair fiber. The first half of the fibers is straight and uncoiled, and the medullary layer is well developed. The second half of the fibers is thin and irregular. It is composed of only one row of medullary cells and has fine hair characteristics. The capillarity of the two types is 15-30 microns, with an average of 23.11 microns. In the coat, the content is less, generally only 1%-5%. The two types of wool are easy to break because of the great difference in diameter at the junction of roughness and fineness, and the value of wool spinning is low.

三、粗毛

3. Coarse hair

粗毛又称枪毛或针毛。是兔毛中纤维更长、更粗的一种，直、硬，光滑，无弯曲，长度10～17厘米，细度31～120微米，平均为47.77微米，一般仅占被毛总量的5％～10％，粗毛型兔可达18％以上。粗毛耐磨性强，具有保护绒毛、防止结毡的作用。根据毛纺工业和兔毛市场的需要，目前粗毛率的高低已成为长毛兔划分生产类型的一个重要性能指标，粗毛型兔毛，适用于粗纺，如生产一般毛衣。

Coarse hair is also called gun hair or needle hair. It is the longest and thickest fibre in rabbit hair. It is straight, hard, smooth and without bending. Its length is 10-17 cm, and its fineness is 31-120 micron, averaging 47.77 micron. It generally only accounts for 5-10% of the total coat. Coarse-haired rabbits can reach more than 18%. Coarse wool has strong wear resistance, and has the function of protecting villus and preventing felting. According to the needs of wool textile industry and rabbit hair market, the roughness rate has become an important performance index for long-wool rabbits to classify production types. Coarse rabbit hair is suitable for woolen spinning, such as the production of general sweaters.
