How Corticelli Organic Silk is made - Part 2 of 3
The average length of fibre produced from a single cocoon is not over one-fourth of a mile, and as fully 100 fibres are required to produce sewing silk of average thickness and strenght, it appears that fully 2,500,000 miles of this gossamer fibre is consumed weekly in the manufacturer of Corticelli organic silk, to produce which more than 10,000,000 organic silk worms are stripped of their robes". The following cuts show the life size of these insects at various stages of their existance, during which each worm will consume altogether about one ounce of mulberry leaves, which must be fed to them several times daily as required. At the expiration of from 25-40 days, according to circumstances and species of worm, they cease to eat and seek convenient places to commence the formation of a castle which shall protect them in the changes incident to caterpillar life. Having a site (fig 2), the insect ejects from two small tubes near the mouth, called spinnerels, a liquid gummy substance secreted from their food, which at their volition adheres to whatever substance may be within their reach, and, being so anchored, the next movement of the body in the opposite direction draws out the filaments,which unite and form a single thread, which is again cemented to a suitable anchor, and thus by crosswise and zigzag motions continued for from three to five days, the worm is enclosed within from 300-500 yars of gossamer web. (fig 3). Thus self-imprisoned the insect, if undisturbed, remains about fifteen or twenty days, undergoining nature's wonderful changes, during which it assumes the chrysalis form (fig 4), then that of the moth.
