Of major interest is the fact that cotton yarn is stronger when wet than when dry. This property is a consequence of the macroand microstructural features of the fiber. As water is absorbed, the fiber swells and its cross section bees more rounded. Usually the absorption of such a large amount of foreign material would cause a high degree of internal stress and lead to weakening of the fiber. In cotton, however, the absorption of water causes a decrease in the internal stresses. Thus, with less internal stresses to overe, the swollen fiber bees stronger. At the same time, the swollen fibers within the yarns press upon each other more strongly. The internal friction strengthens the yarns. In addition, the absorbed water acts as an internal lubricant which imparts a higher level of flexibility to the fibers. This accounts for the fact that cotton garments are more easily ironed when damp. Cotton fabrics are susceptible to shrinkage upon laundering.主要感興趣的是事實，棉紗時干時濕比?！　? Cotton resists sunlight and heat well, although direct exposure to constant strong sunlight will cause yellowing and eventual degradation of the fiber. Yellowing may also occur when cotton goods are dried in gas dryers. The color change is the result of a chemical reaction between cellulose and oxygen or nitrogen oxides in the hot air in the dryer. Cottons will retain their whiteness longer when linedried or dried in the electric dryer.棉花抗太陽光和熱，雖然直接暴露于恒定的強烈的陽光會引起黃的最終降解纖維?！　? Cotton is a moderately strong fiber with good abrasion resistance and good dimensional stability. It is resistant to the acids, alkalies, and organic solvents normally available to consumers. But since it is a natural material, it is subject to attack by insects, molds and fungus. Most prominent is the tendency for cotton to mildew if allowed to remain damp.棉花是具有良好的耐磨性和尺寸穩(wěn)定性好，中等強度的纖維。棉纖維的剛度降低紗線抗起皺能力?！　? Unfortunately, the hydrophilic nature of cotton makes it susceptible to waterborne stains. Watersoluble colorants such as those in coffee or grape juice will penetrate the fiber along with the water。當水進入纖維棉，膨脹，其截面變得更圓。角質(zhì)層是薄的，堅硬的外殼保護纖維生長過程中的破碎和損傷。然而，大多數(shù)棉花遲鈍。　　 The cotton fiber may be from to cm long. Under the microscope it appears as a ribbon like structure that is twisted at irregular intervals along its length. The twists, called convolutions, increase the fibertofiber friction necessary to secure a strong spun yarn. The fiber ranges in color from a yellowish to pure white, and may be very lustrous. However, most cotton dull.?！　?3) Strict middling. （3）嚴格的中等。這些都是由美國農(nóng)業(yè)部提供一個標準的比較。當莢破裂，棉纖維是采摘。紡織機械的發(fā)展，擴大了生產(chǎn)基地。所以勞動力成本會很高。這是因為它容易被毛或亞麻紡成紗由于其更大的長度。s most widely used fiber. Its popularity stems from both its relative ease of production and its applicability to a wide variety of textile products. The price of cotton yarn, however, is strongly dependent upon the cost of labor, so that in the industrialized nations, where labor is expensive, cotton yarns may be relatively high priced.棉花是世界上使用最廣泛的纖維。目錄01課Cotton Growing棉花種植 102課Cotton Properties and Uses棉纖維的特性和用途 204課Wool羊毛 505課 Structure and Properties of Wool羊毛纖維的結(jié)構(gòu)和性能 706課 Silk絲綢 1007課 Flax亞麻 1309課 Rayon人造絲 1612課YARNS 1913課它的流行源于它的生產(chǎn)及其在紡織產(chǎn)品廣泛適用性相對容易。此外，棉纖維要從種子中分離出來的，他們依靠。　　 The invention of the sawtype cotton gin made possible the exploitation of the short staple fiber, which thrived in the Carolinas and Virginia of the United States. The dramatic increase in productivity, coupled with the low cost of labor in the southern United States, gave cotton a continually expanding portion of the world textile market. Increasing mechanization of fiber and yarn production helped keep the cost of cotton goods low. The, development of the textile machinery enlarged the production base.的鋸片式軋棉機的發(fā)明使可能的短纖維的開發(fā)，興盛于美國北卡羅萊納州和弗吉尼亞州。　　 Cotton cultivation requires warm climates with a high level of moisture or irrigation. The growing season is from six to seven months long. During this period the seeds sprout and grow, producing a white blossom in about 100 days. The blossom produces a seed pod, which matures during the next two months. When the pod bursts, the cotton fibers are ready for picking.棉花種植需要溫暖的氣候和水分或灌溉高水平?！　?Before yam manufacture, cotton is graded, sorted, and blended to insure uniform yam quality. Cotton is graded on the basis of color, staple length, fineness, and freedom from foreign matter. In the United States, cottons are divided into grades according to length of staple, uniformity, strength, color, cleanness and flexibility. These are pared with a standard supplied by the United States Department of Agriculture. The standard provides 6 grades above and 6 grades below the Middling grade. The most mon grades are:山藥生產(chǎn)之前，棉花分級，分類，和混合均勻的紗線質(zhì)量的保證。本標準規(guī)定了6級以上，6級以下的中等?！　?4) Middling. （4）中。在顯微鏡下看起來是一個帶狀結(jié)構(gòu)，沿其長度不規(guī)則的時間間隔扭曲?！　?A crosssectional view reveals that the fiber is kidneyshaped with central hollow core known as the lumen. The lumen provides a channel for nutrients while the plant is growing. The fiber consists of an outer shell, or cuticle, which surrounds the primary wall. The primary wall, in turn, covers the secondary wall surrounding the lumen. The cuticle is a thin, hard shell which protects the fiber from bruising and damage during growth. In use as a textile fiber, the cuticle provides abrasion resistance to cotton.管腔提供養(yǎng)分的通道而植物的生長。在用作紡織纖維，角質(zhì)層提供了耐磨抗棉。水分和膨脹時濕讓棉花吸收水的重量約四分之一的高親和力的能力。 when the water evaporates, the colorant is trapped in the fiber. Perhaps the major disadvantage to cotton goods is their tendency to wrinkle and the difficulty of removing wrinkles. The rigidity of cotton fiber reduces the ability of yarns to resist wrinkling. When the fibers are bent to a new configuration, the hydrogen bonds which
