0世纪40年代中期以前，造纸毛毯都是选用羊毛纤维为原料制造的，故此得名为毛毯，现在人们已经惯用这种称呼。

Before the mid-1940s, paper-making blankets were all made of wool fiber, so they are called blankets. Now people have used this term.

与造纸工业的发展相比，我国造纸毛毯行业的发展相对比较滞后。中国造纸毛毯的发展可以说经过三个时代。

Compared with the development of paper industry, the development of China's paper blanket industry is relatively backward. The development of China's paper-making blanket can be said to go through three times.

最早的造纸毛毯始产于上海美伦毛纺织厂（上海工业用呢厂的前身），上海美伦纺织厂是由留日回国学士朱学仁先生于1937年8月创建。在朱学仁先生的带领下，技术人员借鉴国外造纸毛毯生产的经验，经过反复的研究与试验，终于于1941年生产出中国最早的造纸毛毯——羊毛编织造纸毛毯，从此，结束了中国造纸毛毯完全需要进口的历史。这也意味着中国第一代造纸毛毯的诞生，上海美伦纺织厂也就成为中国第一家生产造纸毛毯的专业工厂。

The earliest paper-making blanket was produced in Shanghai Meilun wool textile factory (the predecessor of Shanghai Industrial woolen factory). Shanghai Meilun textile factory was founded in August 1937 by Zhu Xueren, a bachelor returned to Japan. Under the leadership of Mr. Zhu Xueren, technicians learned from the experience of foreign paper-making blanket production, after repeated research and tests, they finally produced China's first paper-making blanket, wool woven paper-making blanket, in 1941. Since then, the history that China's paper-making blanket completely needs to be imported has ended. This also means the birth of China's first generation of paper-making blankets, and Shanghai Meilun textile factory has become the first professional factory in China to produce paper-making blankets.

造纸企业最早均使用编织毛毯，编织毛毯的织造过去一直沿用老设备、老工艺生产。这种毛毯因其制作成本较高、工序繁琐，毛毯的滤水、透气性能不好、尺寸变化较大、寿命较短以及随着新产品的出现而慢慢被造纸行业所淘汰。

Paper making enterprises are the first to use woven blankets. The weaving of woven blankets used to use the old equipment and technology. Because of its high cost, complicated process, poor water filtration and air permeability, large size change, short service life and the emergence of new products, the blanket is gradually eliminated by the paper industry.

中国早期的造纸毛毯是由100%羊毛制成，到50年代末，合成纤维——锦纶开始用于造纸毛毯。锦纶纤维强力高、耐磨性能好，如用15%～20%的锦纶纤维后，造纸毛毯的使用寿命可延长30%～50%左右。60年代初，造纸毛毯在科技领域的另一个成果是“变性处理”。因为羊毛含有蛋白质，纸浆中的细菌会破坏羊毛纤维，经采用变性处理后，可改变羊毛中的某种分子结构，以提高它的抗生物、抗化学和耐热性能。处理后的毛毯可延长寿命15%～50%左右。

In the early days of China, paper-making blankets were made of 100% wool. By the end of the 1950s, synthetic fiber nylon began to be used in paper-making blankets. Nylon fiber has high strength and good wear resistance. For example, after using 15% - 20% nylon fiber, the service life of paper blanket can be extended by about 30% - 50%. In the early 1960s, another achievement of papermaking blanket in the field of science and technology was "denaturing treatment". Because wool contains protein, bacteria in pulp will destroy wool fiber. After denaturing, some molecular structure of wool can be changed to improve its biological, chemical and heat resistance. The service life of the treated blanket can be prolonged by 15% - 50%.

70年代初期，针刺植绒毛毯的研制成功，打破了过去羊毛机织毛毯一统天下的局面，同时也标志着我国第二代造纸毛毯的诞生。随后不久，我国第一台无纬针刺植绒机在上海研制成功，创造了“织布不用梭，整理不用水”的纺织生产新技术。之后，我国纺织行业的工程师们经过潜心的研究，独辟蹊径，他们正视当时国内无可溶性化学纤维的现实，舍弃现成的织布方式，超越了国外技术权威的框架思路，自力更生，自主研制，终于研制成功了我国独具特色的无纬针刺植绒造纸毛毯，而且毛层所用的原料基本上以锦纶、涤纶为主。这项技术当时在国际上尚属空白。

In the early 1970s, the successful development of needled flocking blanket broke the situation that wool woven blanket dominated the world in the past, and also marked the birth of the second generation of paper-making blanket in China. Soon afterwards, the first weftless needle flocking machine in China was successfully developed in Shanghai, creating a new textile production technology of "no shuttle for weaving, no water for finishing". After that, the engineers in China's textile industry, through their dedicated research, took a new approach. They faced up to the reality of insoluble chemical fiber in China at that time, abandoned the ready-made weaving methods, went beyond the framework thinking of foreign technical authority, self-reliance, independent research and development, and finally developed the unique weft free needled flocking paper blanket in China, and the raw materials used for the wool layer Basically, it is mainly made of nylon and polyester. At that time, this technology was still blank in the world.

至此我国开始成批生产普通针刺（BOB）造纸毛毯。BOB毛毯是由基布层和纤维层组成，基布一般占成品重量的20%～50%，它分为有纬、稀纬、细纬和无纬等多种，经线为混纺纱与锦纶长丝合股，以增加拉力，缩小纱支体积，有利于规格的稳定与滤水。基布的经纬密度小，特别是用稀纬、细纬和无纬制成的毛毯，可以减少排水阻力，提高毛毯滤水性能。纤维层的原料一般采用锦纶和涤纶短纤维，表面非常耐磨，可以改善或消除纸面毯痕，提高纸张平滑度。基布层和纤维层经针刺机刺针的反复针刺，使之牢固地结合在一起，既达到保护基布的目的，又增加了毛毯的滤水性能。

So far, China began to produce ordinary needled (Bob) paper-making blankets in batches. Bob blanket is composed of base cloth layer and fiber layer. The base cloth generally accounts for 20% - 50% of the weight of the finished product. It can be divided into weft, thin weft, fine weft and no weft. The warp yarn is composed of blended yarn and nylon filament to increase the tension, reduce the volume of yarn, and facilitate the stability of specifications and water filtration. The warp and weft density of the base cloth is small, especially the blanket made of thin weft, fine weft and no weft, which can reduce the drainage resistance and improve the water filtering performance of the blanket. The raw materials of the fiber layer are generally nylon and polyester staple fibers. The surface is very wear-resistant, which can improve or eliminate the paper blanket mark and improve the paper smoothness. The base cloth layer and the fiber layer are repeatedly needled by the needle of the needling machine, so that they are firmly combined, which not only achieves the purpose of protecting the base cloth, but also increases the water filtering performance of the blanket.

BOB毛毯与编织毛毯相比，具有滤水透气性好、生产工艺简单、制作方便、使用寿命长等特点，是我国造纸行业较为普遍使用的产品。其使用寿命可比编织毛毯延长50%～100%，从而降低了每吨纸的毛毯单耗和生产成本，也减少了换毯停机时间，提高了纸机运行效率。BOB毛毯的出现，使中国第二代造纸毛毯的性能更加完美，这种产品，无论是滤水性能，还是表面平整性能、防脱毛性能、使用寿命等性能，都远远好于原来的产品，而且制作成本还相当的低。

Compared with woven blankets, Bob blankets are widely used in China's paper industry due to their advantages of good water filtration and air permeability, simple production process, convenient production and long service life. The service life of the machine can be extended by 50% - 100% compared with that of the woven blanket, thus reducing the unit consumption and production cost of the blanket per ton of paper, reducing the down time of changing the blanket, and improving the operation efficiency of the paper machine. With the appearance of Bob blanket, the performance of China's second generation papermaking blanket is more perfect. This kind of product, whether it is water filtration performance, surface evenness performance, anti depilation performance, service life and other performance, is far better than the original product, and the production cost is also quite low.

80年代以来随着造纸工业迅猛发展，一些宽幅、高速、高线压造纸机相继在我国纸厂应用，这类纸机对与之配套的造纸毛毯的要求也相应地提高，BOB毛毯已不能满足新型纸机的要求，为了正常生产，一些纸厂从国外进口了BOM毛毯。自此，我国造纸行业才开始对BOM毛毯产生认识。西方一些造纸发达的国家从60年代末起已开始对BOM毛毯进行研制和推广，我国则是从80年代末90年代初开始这项工作，这也就意味着，中国的第三代造纸毛毯比发达国家晚出现近20年的时间。目前BOM造纸毛毯已逐步成为市场的主导产品，其普及率约在80%左右。

Since the 1980s, with the rapid development of paper industry, some wide, high-speed and high-speed press paper machines have been applied in China's paper mills one after another. The requirements of this type of paper machine for the matching paper blanket have also been correspondingly increased. Bob blanket can no longer meet the requirements of the new paper machine. In order to produce normally, some paper mills have imported BOM blanket from abroad. Since then, China's paper industry began to recognize BOM blanket. Some developed countries in the West have begun to develop and promote BOM blankets since the end of 1960s, while China started this work from the end of 1980s and the beginning of 1990s, which means that China's third generation paper blankets appeared nearly 20 years later than developed countries. At present, BOM paper blanket has gradually become the leading product in the market, and its popularity rate is about 80%.

BOM毛毯由底网层和纤维层组成。底网层采用单丝和单、复丝合股化纤材料，运用不同织造技术制作成单层、双层、多层、叠层（1+1，1+2，2+2┄）等组织结构的无端织物；纤维层常用的合成纤维主要有锦纶短纤、涤纶短纤和其他纤维原料等；将相同或不同粗细度的短纤在底网上进行

BOM blanket consists of bottom net layer and fiber layer. The bottom web layer is made of monofilament, monofilament and multifilament synthetic fiber materials, and different weaving technologies are used to make single-layer, double-layer, multi-layer and laminated (1 + 1, 1 + 2, 2 + 2 ┄). The common synthetic fibers of the fiber layer are mainly nylon short fiber, polyester short fiber and other fiber materials. The same or different thickness of short fiber is carried out on the bottom web
