the sound parts of the cocoon are wound on to reels as single filament and assembled into multiple filament yarns of various types

Answer 1

帮你百度了一下……

Silk is produced by silk worm. The silk worm extends the filament from its twin spinnerets when making its cocoon. The filament, consisting ofprotein, is coated with an alkali-soluable substance called sericin. The silk industry was founded in China and for three thousand years China held a monopoly on the world silk industry. In the process of reeling the silk filament from the cocoon, the outer and inner layers are discarded as waste.
【The sound parts of the cocoon are wound on to reels as single filament and then assembled into multiple-filament yarns of various types】 Silk is very strong with a tenacity usually ranging from 3-5 grams per denier. The wet strength is 80%-85% of the dry strength. The elongation of silk filament is 25% under normal conditions and is 35% at 100% R.H. The elastic properties of silk is better than those of cotton or rayon but are not as good as wool’s. Like wool, silk absorbs moisture readily and can take up a third of its weight of water without feeling wet to the touch. It has a regain of 11.0%. Silk will withstand higher temperature than wool without decomposing. It will withstand a high temperature of 140℃ for prolonged periods. However, it will decompose at 175℃. Silk is less readily damaged by alkali than is wool and like wool it is also insoluble in common solvents.

蚕丝是蚕制作出来的。蚕作茧时，从嘴里的两个吐丝口吐出蚕丝。蚕丝由蛋白质构成，其表面包覆有一层可溶于碱的被称为丝胶的物质。 丝绸工业起源于中国，三千年以来中国一直垄断着世界丝绸工业。 在从蚕茧上将蚕丝卷绕下来的过程中，蚕茧的内外层会被作为废物丢弃掉，【蚕茧的主体部分则以单丝方式卷绕到线轴上，然后合并成不同规格的复丝纱线。】 蚕丝的强度很高，其强力范围为3-5克/旦尼尔。湿强度是干强度的80％-85％。在正常条件下，蚕丝的伸长率为25％，在相对湿度100％时为35％。 蚕丝的弹性比棉纤维和人造丝要好，但稍逊于羊毛。与羊毛相同，蚕丝很容易吸收水分，它能吸收相当于自重1/3的水量，在触摸时仍然不会感到潮湿。蚕丝回潮率为11.0％。 蚕丝的耐热性比羊毛好，且在高温下不易分解。蚕丝可以长时间承受140℃的高温，尽管如此，在温度达到175℃时，蚕丝也会分解。 蚕丝不像羊毛那样容易被碱损伤，但在一般溶剂中不易被溶解的性能与羊毛很相似。

追问

能不能分析下句子结构 尤其是 are wound on 哪里不懂啊

追答

are wound被动语态。
wound是wind（vt.缠绕；卷绕）的过去分词形式。
on to是复合介词，表示“到……上”。

are wound on to即“被缠绕到……上”。
