    細毛也叫細毛。它是長毛兔皮毛中更柔軟、更纖巧的毛纖維,呈波浪狀和弧形,長5 ~ 12厘米,細度7 ~ 30微米,平均14.99微米。絨毛兔的毛含量一般占毛總量的80% ~ 93%。兔毛纖維的質量在很大程度上取決于細毛纖維的數量和質量。
      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.
      鱗片一般呈圓形重疊排列,鱗片末端自由。髓質由一層多邊形細胞縱向排列,因此皮質相對較厚。
      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.
      二、兩型毛
      2、 Dichotomous hair

      分叉指的是一根頭發纖維上有兩種類型的纖維。纖維上半部分呈扁平狀,無卷曲,髓層發達,有粗毛的特點,纖維下半部分較薄,卷曲不規則。它僅由單列髓細胞組成,具有細毛的特征。兩種類型的毛細度為15-30微米,平均為23.11微米。頭發中的含量較少,一般只占1% ~ 5%。由于兩種羊毛的直徑不同,容易斷裂,毛紡值低。
      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.
      第三,蓬松
      Third, fluffy
      粗糙的毛發也被稱為槍毛或針毛。是兔毛中更長更厚的纖維,直、硬、光滑、不彎曲,長度10 ~ 17厘米,細度31 ~ 120微米,平均為47.77微米,一般只占毛總量的5% ~ 10%,粗毛型兔毛可達18%以上。粗糙的毛發抗磨性強,具有保護絨毛、防止毛氈的作用。根據羊毛行業和兔毛市場的需求,粗毛率已成為長毛兔生產類型分類的重要性能指標。
      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.
