人們都知道蠶兒會吐絲結繭,可是絲是怎樣製造出來的,卻不一定完全清楚。原來蠶兒幼蟲的身體內,有一套結構完整、構造複雜的叫做絲腺體的造絲系統。絲腺體連接著頭部下面叫做擠壓器的吐絲泡,由這兩個基本部件組成一台“天然紡織機”。一隻老熟幼蟲的身體內,有兩列細胞組成的絲腺體,它要比身體長5倍,並且與貯藏絲液的袋狀囊相通。頭上的擠壓器與周圍的肌肉連接著,蠶兒吐絲時,頭上的肌肉不停地伸縮,將絲腺體中的絲液抽壓出來,絲液與空氣接觸後,便形成細長的絲。
 
  蠶兒吐絲結繭時,它的頭總是時而抬高,時而垂下,並不停地左右擺動著。如果用放大鏡仔細觀察,蠶兒作繭的絲,是一個個排列得很整齊的“8”字形絲圍,每20多個絲圈叫做一個絲列。當繭的一頭織好後,它會來個1800大轉彎,開始織繭的另一頭,因此,家蠶的繭子都是兩頭稍粗,中間稍細,很像一顆花生。蠶兒每結好一枚繭,需要轉換250一500次位置,編織約6萬個“8”字形絲圍,每個絲圍約有0.72釐米長。蠶兒就是這樣不停地織呀織的,將自己體內的絲完全抽盡後,才化蛹變娥,接種傳代,世世代代為人類造福。

The people knew that the silkworm meets the spinning to spin a cocoon, but how is the silk makes, not necessarily completely is actually clear. Originally in the silkworm larva's body, some set of structures are complete, the structure complex named silk gland makes the silk system. The silk gland connects under the forehead to be called the extrusion to spit the trychocyst, is composed a natural spinner old ripe larva by these two basic parts in the body, two rows cells compose the silk gland, it must compared to body length of body 5 times, and with stores the silk fluid the baggy pouch to be interlinked. On extrusion is connecting with the periphery muscle, when silkworm spinning, on muscle does not stop expands and contracts, pulls out the silk gland's in silk fluid presses, after silk fluid and air contact, then forms the tall and slender silk.    When the silkworm spinning spins a cocoon, its head always from time to time raises, from time to time dangles, does not stop about the place to swing. If observes carefully with the magnifying glass, the silkworm makes the cocoon the silk, is one all arranges the very much neat glyph silk to encircle, every more than 20 bobbins are called a silk row. After cocoon weaves, it will come 1800 shallowturn, will start to weave the cocoon another head, therefore, the bombyx mori cocoon will be two hairs is thick, middle slightly thin, will look like a peanut very much. A silkworm each knot cocoon, needs to transform 2,501,500 times the position, weaves the approximately 60,000 glyph silk to encircle, each silk encircles approximately has 0.72 centimeter to be long. The silkworm is this does not stop weaves weaves, pulls out completely after in vivo's silk completely, only then the pupation changes E, the vaccination transfer of generation, benefitted for generations for the humanity.

People all know geobombycis will weaving silk cocoon, but is made, it's not completely clear. The original silkworm larvae of the body, with a set of structural integrity, constructed complex called silk gland of silk system. Silk gland are connected to the head of the following is called osteotomes by blowing bubbles as the two basic components that make up a natural for “. ” A mature larvae of the body, there are two columns of silk gland, it 5 times than the body, and the storage of liquid silk capsule. Head of osteotomes and worldaround are connected to the muscles, silkworm spins, the head of the non-stop for expansion and contraction of the muscles, the silk silk gland in liquid pressure and wire-liquid contact with air, forming calledya.
 
  Silkworm weaving cocoon, it is always the head of the elevationacute, sometimes tarumizu and without oxygen, and the left and right. If you use the magnifying glass to look closely, SilkWorm 作茧 silk, are arranged neatly ” “ 8 of silk surrounding each of the glyphs on more than 20 silk silk circle is called a column. When cocoo upperend weaving in place, it'll 1800 turns and began to weave the other side of cocoo, as a result, SilkWorm cocoons are shoulderpieces for a little rough, with a little light, much like a peanut. Silkworm each knot us83 cocoo, needs to be converted 250 a 500 times location, woven around 6 000 ” “ 8 font style wire Wai, each wire Wai about 0.72 cm long. Geobombycis is such a non-stop for weaving havemany, silk is himself completely exhausted before pupation variable e, vaccination passage of humanity, from generation to generation.
