        不同柔軟程度的兔毛有不同的作用

        發(fā)布日期:2018-04-26 來源:http://www.chle.cn 發(fā)布人:admin

          兔毛纖維按其粗細(xì)、長(zhǎng)短、彎曲形態(tài)和髓層的發(fā)達(dá)程度,可將兔毛纖維大體分為細(xì)毛(絨毛)、兩型毛和粗毛(槍毛)3種類型。

          The rabbit hair fiber can be divided into 3 types, such as fine hair (Rong Mao), two type hair and coarse wool (gun hair), according to the thickness, length, curved shape and the developed degree of the pulp.

          兩型毛是指單根毛纖維上有兩種纖維類型。纖維的上半段平直無卷曲,髓質(zhì)層發(fā)達(dá),具有粗毛特征,纖維的下半段則較細(xì),有不規(guī)則的卷曲,只由單排髓細(xì)胞組成,具有細(xì)毛特征。兩型毛細(xì)度為15-30微米,平均23.11微米。在被毛中含量較少,一般僅占1%~5%。兩型毛因粗細(xì)交接處直徑相差很大,極易斷裂,毛紡價(jià)值較低。

          Type two hair is a single wool fiber with two types of fiber. The upper part of the fiber is straight and without curl, the medulla layer is developed, it has the characteristics of coarse hair, the lower part of the fiber is fine, and it has irregular curls. It is only composed of single row of myelinated cells with fine hair characteristics. The size two is 15-30 microns, with an average of 23.11 microns. Less content in the coat, generally only 1% to 5%. The diameter of the two type of wool is quite different from that of the coarse and fine junction, so it is easy to break and the wool spinning value is low.

          細(xì)毛又稱絨毛。是長(zhǎng)毛兔被毛中更柔軟纖細(xì)的毛纖維,呈波浪形彎曲,長(zhǎng)5~12厘米,細(xì)度為7~30微米,平均為14.99微米,絨毛型兔的絨毛含量一般占被毛總量的80%~93%。絨毛型長(zhǎng)毛兔的毛纖維質(zhì)量,在很大程度上取決于細(xì)毛纖維的數(shù)量和質(zhì)量,細(xì)毛在毛紡工業(yè)中適用于加工精紡產(chǎn)品如高檔純毛內(nèi)衣、內(nèi)褲和呢料等。

        長(zhǎng)毛兔

          The fine hair is also called the villi. It is the most soft and fine wool fiber in the hairy rabbit. It is wavy, 5~12 cm long and 7~30 microns in fineness. The average amount is 14.99 microns. The villi of villous rabbit accounts for 80% to 93% of the total hair. The wool fiber quality of the villous long haired rabbit depends largely on the quantity and quality of the fine wool fibers. The fine wool is suitable for processing worsted products such as high-grade pure wool underwear, underwear and advanced woolen materials in the wool spinning industry.

          鱗片一般呈環(huán)狀復(fù)疊式排列,鱗片端呈游離狀。髓層由單層多角細(xì)胞點(diǎn)狀縱向排列,因此,皮質(zhì)層相對(duì)較厚。

          The scales are generally arranged in a circular pattern, and the scales are free. The medullary layer is arranged longitudinally from a single layer of polygonal cells, so the cortical layer is relatively thick.

          粗毛又稱槍毛或針毛。是兔毛中纖維更長(zhǎng)、更粗的一種,直、硬,光滑,無彎曲,長(zhǎng)度10~17厘米,細(xì)度31~120微米,平均為47.77微米,一般僅占被毛總量的5%~10%,粗毛型兔可達(dá)18%以上。粗毛耐磨性強(qiáng),具有保護(hù)絨毛、防止結(jié)氈的作用。根據(jù)毛紡工業(yè)和兔毛市場(chǎng)的需要,目前粗毛率的高低已成為長(zhǎng)毛兔劃分生產(chǎn)類型的一個(gè)重要性能指標(biāo),粗毛型兔毛,適用于粗紡,如生產(chǎn)一般毛衣。

          The coarse wool is also called the gun hair or the needle hair. It is the longest and thickest kind of fiber in rabbit hair. It is straight, hard, smooth and without bending. The length is 10~17 centimeters. The fineness is 31~120 microns. The average is 47.77 microns. Generally, it only accounts for 5% ~ 10% of the total amount of wool, and the rough haired rabbit can reach more than 18%. Coarse wool has strong abrasion resistance, and has the function of protecting villi and preventing felting. According to the needs of the wool textile industry and the rabbit hair market, the roughing rate has become an important performance index for the division of the production type of the long haired rabbit. The coarse haired rabbit hair is suitable for the coarse woolen, such as the production of the general sweater.
