SILK
A silk comforter (絲綿被/蚕丝被) is a bed covering, most often used as a duvet, and also commonly referred to as a silk duvet, silk quilt, or silk blanket. Originally used and made in China, since the late 20th century, silk comforters have become more common in Western market areas. Their increasing popularity stems from a combination of factors, including their thermal properties, their light weight, and their natural hypoallergenic properties. The opening of the Chinese market to the world since the 1990s has also played a significant role in the spread of silk comforters, as China is both the world's biggest silk producer and silk comforter manufacturer.
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 on a spindle for use in the textile industry. Silk is used for 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, which will fill the comforter.
The cocoons are first boiled to loosen the sericin holding the filaments together and kill the silkworm. Each cocoon is stretched 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 imported mainly from China or Taiwan and are priced about the same as down comforters. Unlike other natural fibers used in comforters, silk is naturally hypoallergenic, and it does not require any processing chemicals during the manufacturing process. A silk comforter is a good alternative for people who are allergic to goose down comforters.
Silk comforter care
Silk comforters are easy to care for: they only need to be dried under the sun twice a year to maintain their freshness. If more thorough cleaning is required, a silk comforter should be dry-cleaned, since the silk floss layers are damaged by contact with water.
They may have a fairly strong smell to them, attributed to the remaining pupa. There is some difference of opinion about how easy it is to get rid of the smell.
Cost in China
In November 2017, at a large government silk products store in Shanghai, the cost for a 100% silk queen-sized 2 kg silk quilt (duvet, comforter) had the 'fixed price' of Yuan 1880 or approximately U.S. $285 (there are no additional costs). Government fixed-price stores, which one can apparently trust as regards quality, sometimes allow customers to bargain. The price is composed of two parts: one is the silk filler, and the other is the cotton cover.
丝绸被子（silm comfort）是一种床罩，通常被用作羽绒被，通常也被称为真丝羽绒被，丝绸被子或丝绸毯子。自20世纪末以来，丝绸床罩最初在中国使用和制造，在西方市场区域已变得越来越普遍。它们越来越受欢迎的原因包括多种因素，包括其热性能，重量轻和天然的低变应原性。自1990年代以来，中国市场对世界的开放在蚕丝被的传播中也发挥了重要作用，因为中国既是世界最大的蚕丝生产国，又是蚕丝被的生产国。
生产加工
蚕丝来自蚕的茧，在亚热带气候中，蚕以桑树为食。当茧煮沸时，坚硬的茧变成一个松散的球，球长超过1000米，结实而柔韧。通常，该球被解开并缠绕在纺锤上以用于纺织工业。丝绸用于制作从衣服到地毯的所有物品。然而，在丝绸床罩生产过程中，不会解开丝绸长丝，而是将其拉伸成缠结的扁平网并分层以形成丝线，从而填充床罩。
首先将茧煮沸，使丝胶松弛，丝胶将细丝束缚在一起并杀死蚕。手工将每个茧放在U形的木架子上，并且球线变成一片缠结的纤维。然后，在较大的架子上再用手工拉伸该床单，以及其他几个茧，制成厚实的棉束，称为丝线。需要数百捆这些东西才能制成丝绸被子。
一旦足够的丝茧被拉成束，被子就开始成型。工人抓住捆束的边缘并将其拉伸至与所需的床罩的尺寸相匹配的程度，然后床罩逐渐形成。这些薄层可能需要100到400个之间的任何厚度才能制成床罩，具体取决于床的尺寸和所需的厚度。由于制作每一层都需要许多茧，因此丝绸被子可能由数千个丝绸茧组成。
将蚕丝纤维层堆叠在一起后，将它们密封在蚕丝或棉织物内，即可制成棉被。尽管真丝被子很厚，但结果还是非常轻便。蚕丝被提供了与羽绒相似的出色绝缘性能，但体积却比羽绒被小。丝绸是一种透气的面料，可以使丝绸床罩在很宽的温度范围内保持舒适。甚至在夏天也使用薄的丝绸床罩。
在美国，丝绸被子主要从中国或台湾进口，其价格与羽绒被大致相同。不同于其他用于床罩的天然纤维，丝绸具有天然的低过敏性，并且在制造过程中不需要任何加工化学品。对于那些对鹅绒被子过敏的人来说，丝绸被子是一个不错的选择。
真丝棉被护理
丝绸床罩很容易保养：它们每年仅需在阳光下干燥两次即可保持其新鲜度。如果需要进行更彻底的清洁，则应该对丝绸床罩进行干洗，因为丝绸线层会因与水接触而受损。
他们可能对他们有相当强烈的气味，这归因于剩余的。对于消除异味有多容易，存在一些意见分歧。
中国成本
2017年11月，在上海一家大型政府丝绸产品商店里，一件100％的丝绸大号2公斤丝绸被子（羽绒被，被子）的价格为``固定价格''1880元人民币或约285美元（没有额外费用）。显然可以信任的政府固定价格商店有时会允许客户讨价还价。价格由两部分组成：一个是丝绸填充物，另一个是棉线套。
