1、Lesson Four四课Wool羊毛 The early history of wool is lost in antiquity. Sheepskin, including the hair, was probably used long before it was discovered that the fibers could be spun into yarns or even felted into fabric. There is no evidence to support the theory that wool was the first fiber to be proce

2、ssed into fabric, but it seems certain that, as a part of the skin, wool was used for covering and protection by prehistoric peoples long before yarns and fabrics were made.羊毛的早期历史失传了。羊皮，包括头发，可能很久以前发现的纤维可纺成纱线或织成织物毡。没有证据支持，羊毛被加工成的织物的第一光纤的理论，但似乎肯定的是，作为皮肤的一部分，羊毛被用于覆盖和保护的史前人类早在纱线和织物进行了。The earliest frag

3、ments of wool fabric have been found in Egypt, probably because of the preserving qualities of the climate. These have been dated from 4000 to 3500 B C. The earliest example of wool fabric found in Europe has been dated about 1500 B C; it was unearthed in archeological digs in Germany. Danish sites

4、have yielded excellent fragments of early wool fabrics dated about 1300 to 1000 BC. These fabrics are rough and coarse and contain considerable wild sheep hair.毛织物最早的碎片已经被发现在埃及，可能是因为保鲜品质的气候。这些已经从公元前4000到公元前3500 。最早的羊毛织物的发现在欧洲已经于约公元前1500 ；这是出土的考古发掘，在德国。丹麦的网站已经取得了优良的片段的早期的羊毛织物约公元前1300至公元前1000年。这些织物粗糙，

5、含有大量的野生绵羊毛。 Wool is a natural fiber of animal origin. Though vegetable fibers were probably the first to be used for spinning and weaving into cloth, animal fibers in the form of skins were the earliest type of clothing worn by man.羊毛是来自于动物的天然纤维。尽管植物纤维可能被用于纺纱和织布的第一，在动物毛皮纤维最早的人穿的服装类型。 There are indic

6、ations that, as early as the seventh century BC, people began to sell and buy woolen goods. The supply of wool available to the world every year amounts to about 5000 million pounds. After scouring, this is reduced to about 3000 million pounds of pure wool. The wool crop is insufficient to meet the

7、world needs. Pure wool is often mixed with other type fibers and recovered wool to meet the demand.有迹象表明，早在公元前第七世纪，人们开始买卖毛织品。羊毛每年向世界供应量的大约500千万磅。冲刷后，这是减少到大约300千万磅的纯羊毛。羊毛的产量不能满足世界的需要。纯羊毛通常与其它纤维的混合和再生毛满足需求。 The qualities of different wools vary greatly. The merino sheep of Australia, South America and

8、 South Africa produce very free and soft wool. The quality of wool from these sources depends upon the conditions and heritage of the sheep. Port Philip wool is the finest in Australia and is used to produce the highest quality woolen and worsted fabrics.不同品种的羊毛在质量上存在较大的差异。澳大利亚细毛羊，南美国和南非产生非常自由和柔软的羊毛

9、。从这些来源的羊毛的质量取决于羊的饲养条件和品种。菲利普港羊毛是澳大利亚最好的，被用于生产粗纺和精纺毛织物质量最高的。 Wool from South Africa is very wavy with a good white color and is used for good quality worsted and woolen goods. South American wool is usually of lower quality than wool from Australia or South Africa. Merino wool has been successfully r

10、aised in Germany, France, Spain and the United States and is of high quality.南非产的羊毛是一个好的白色非常波浪和用于优质的精纺呢绒。南美洲羊毛通常是低质量比从澳大利亚或南非羊毛。美利奴羊毛已在德国，成功地提高了法国，西班牙和美国是高质量的。 To provide the freest-quality wool, production is scientifically controlled. Sheep are inoculated against disease, dipped in chemicals to pr

11、otect them against insects, and unless on rangeland, fed diet designed to produce healthy animals.提供最优质的羊毛，生产的科学控制。绵羊接种抵抗疾病，浸泡在化学物质来保护他们免受昆虫，除非在草地，设计生产出健康的动物饲料。 Wool can be sheared from the living animal or pulled from the hide after the animal has been slaughtered for its meat. Sheared wool is call

12、ed fleece or clip wool and is quality to pulled wool, which is taken from the hides of slaughtered sheep Wool considered superior剪羊毛可以从活的动物或从隐藏拉后，动物被屠宰后的肉。剪羊毛是羊毛或羊毛和质量夹毛被，这是从宰羊羊毛被认为是优越的隐藏 Shearing is currently done very rapidly with power shears. A good worker can completely shear a sheep in less th

13、an one minute, sometimes as short as 20 seconds. Recent developments in Australia have led to a process called chemical or biological shearing. The animal is fed a chemical similar to that used in the treatment of cancer, which cause the hair to fall out within two weeks. Within very short time foll

14、owing the loss of the hair, it starts to grow again, and the sheep suffer no damage. Fibers obtained in this way are slightly longer than those sheared from the animal, and there appears to be less physical damage to the fibers.剪切当前功率迅速完成剪。一个好的工人可以完全剪力在不到一分钟，一只羊，有时短为20秒。澳大利亚最近的事态发展导致的过程被称为化学或生物剪。动物喂

15、食化学相似，用于癌症的治疗，导致头发脱落两周内。头发的损失后，在很短的时间内，它又开始生长，和羊不受损害。以这种方式得到的纤维比剪切从动物稍长，似乎有对纤维的物理伤害少。 Usually shearing is done once a year in the early spring, and the fleece is removed in one piece, rolled, packed into bags, and shipped to the nearest processing center. Pulled wool is removed from the hide by one

16、of two methods. It may be treated with a depilatory that loosens the fiber and permits it to be pulled away from the skin without damaging the hide, or it Can be loosened by the action of bacteria on the root end of the fiber. Pulled wool is usually mixed with fleece or clip wool before processing i

17、nto yarns and fabrics.通常剪切是一年做一次在早春，和羊毛是一块，删除卷，包装成袋，并运到最近的加工中心。拔毛是由两种方法中的一种从隐藏删除。它可以用脱毛，松开纤维和允许它被拉离皮肤无损伤隐藏处理，或者可以通过细菌对纤维的根端动作放松。拔毛通常与羊毛或羊毛混合前夹加工成纱线和织物。 Preliminary grading of wool fibers is done while they are still in the fleece, because this step is important in determining cost. Factors used in d

18、etermining the grade of wool include fiber fineness or diameter and length, the age of the animal, the natural color, the breed of the sheep, and the condition under which the animal lived. After grading, fleeces are shipped to the mill, where they are prepared for further processing into yarns and

19、fabrics.初步的羊毛纤维的分级是还在羊毛做的，因为这一步确定成本是很重要的。用于测定棉纤维细度和品位的因素包括直径和长度，年龄的动物，自然的色彩，羊的品种，和的情况下，动物的生活。评分后，羊毛被运送到工厂，在那里他们准备进一步加工成纱线和织物。 Wool is attacked by hot sulfuric acid and decomposes completely. most other mineral acids of all strengths. Wool will dissolve in caustic soda solutions that would have little effect on cotton.羊毛是由热硫酸袭击并完全分解。大多数其它不同浓度的无机酸。羊毛会溶解在烧碱的解决方案，将对棉花的影响不大。
