blanket

A blanket is a piece of soft cloth large enough either to cover or to enfold a great portion of the user's body. It is usually used when a person goes to sleep or is otherwise at rest. It traps radiant bodily heat that otherwise would be lost through convection [热的对流], helping to keep the user warm. Many children and adults use a blanket as a comfort object.

The term arose from the generalization of a specific fabric called Blanket fabric, a heavily napped woolen weave pioneered by Thomas Blanket (Blanquette), a Flemish weaver who lived in Bristol, England, in the 14th century. 这个词源于对一种叫做毯子织物的特殊织物的泛化。毯子织物是由14世纪居住在英国布里斯托尔的佛兰芒织工托马斯·毯子（Blanquette）开创的一种毛绒织物。Flemish means belonging or relating to the region of Flanders in northern Europe, or to its people, language, or culture. 佛兰芒是指属于或关于北欧佛兰德斯地区，或其人民、语言或文化的。

Many types of blanket material, such as wool, are used because they are thicker and have more substantial fabric to them, but cotton can also be used for light blankets. Wool blankets are warmer and also relatively slow to burn compared to cotton. The most common types of blankets are woven acrylic, knitted polyester, mink, cotton, fleece and wool. Blankets also come with exotic crafting and exotic material such as crocheted afghan or a silk covering. The term blanket is often interchanged with comforter, quilt, and duvet, as they all have similar uses. 许多类型的毯子材料，例如羊毛，之所以被使用，是因为它们更厚，并且有更坚固的织物，但棉花也可以被用于轻质毯子。与棉花相比，羊毛毯子更暖和，燃烧速度也相对较慢。最常见的毯子有机织亚克力、针织聚酯、貂皮、棉、绵羊/绒毛和羊/类羊毛。毯子还配有异国工艺和异国材料，如钩编阿富汗或丝绸覆盖物。毯子这个词经常与被子、被子和羽绒被互换，因为它们都有相似的用途。

Blankets have been used by militaries for many centuries. Militaries are some of the biggest single consumers of woolen blankets. Military blankets tend to be coarse grey, with thick fibers of over 20 microns. 许多世纪以来，军队一直使用毯子。军队是毛毯最大的单一消费者之一。军用毛毯一般为粗灰色，粗纤维超过20微米。
