Production and Processing
Silk comes from the cocoons of the silkworm, which feeds off mulberry trees in subtropical climates. When the cocoon is boiled, the hard cocoon becomes a loose ball of strong, flexible filament measuring over 1,000 meters. Usually, this ball is uncoiled and wrapped onto a spindle for use in the textile industry making everything from clothing to rugs. During silk comforter production, however, the silk filament is not unraveled, but rather stretched into a flat tangled web and layered to form silk floss.
The cocoons are first boiled to loosen the sericin holding the filaments together and remove the silkworm. Each cocoon is expanded outwardly by hand on a U-shaped wooden rack, and the ball of thread becomes a sheet of tangled fibers. This sheet is then hand-stretched again on a larger rack along with several other cocoons to make a thick, cottony bundle called silk floss. It takes hundreds of these bundles to make a silk comforter.
Once enough silk cocoons have been stretched into bundles, the comforter begins to take shape. Workers grab the edges of the bundle and stretch it wide to match the dimensions of the desired comforter, and layer by layer the comforter begins to take shape. It can take anywhere between 100 and 400 of these thin layers to make a comforter, depending on bed dimensions and desired thickness. Since it takes many cocoons to make each layer, a silk comforter may be composed of thousands of silk cocoons.
Once the silk fiber layers are stacked together, they are sealed inside silk or cotton fabrics and the comforter is complete. The result is extremely light-weight despite the silk comforter's thickness. Silk comforters provide excellent insulating properties similar to down, but tend to be less bulky than down duvets. Silk is a breathable fabric, making silk comforters comfortable in a wide temperature range. Thin silk comforters are used even in the summer.
In the U.S., silk comforters are mainly imported from China or Taiwan and are priced roughly the same as down comforters. Unlike other natural fibers used in comforters, silk is naturally hypoallergenic, and also does not require any chemicals during the manufacturing process. A silk comforter is a comparable alternative for people who are allergic to goose down comforters.

Famous quotes containing the word production:
“An art whose limits depend on a moving image, mass audience, and industrial production is bound to differ from an art whose limits depend on language, a limited audience, and individual creation. In short, the filmed novel, in spite of certain resemblances, will inevitably become a different artistic entity from the novel on which it is based.”
—George Bluestone, U.S. educator, critic. “The Limits of the Novel and the Limits of the Film,” Novels Into Film, Johns Hopkins Press (1957)
