采用纤维长度38/39毫米以上的细绒棉纺纱,织成的棉织品最薄、最结实;以纤维长度36/37毫米长俄棉作原料纺织品数量较少;其余的棉织品都是选用纤维长度为27/28—34/35毫米作原料,因此,世界棉花市场是以纤维长度进行分级的。世界生产细绒棉38/39毫米的主要国家有:埃及、苏联、印度、苏丹、美国、秘鲁。最近十年苏联细绒棉纤维产量由79千吨增加到138千吨;印度由68千吨增加到246千吨,增长2.6倍;同期埃及细绒棉纤维产量却减少一半,从217千吨下降到106千吨,这是由于世界棉花市场行情的变化,政府采取 The use of fine fiber cotton yarn length of 38/39 mm or more, woven into the thinnest and most solid; with a length of 36/37 mm fiber long Russian cotton as a raw material for the textile less; the remaining cotton fabrics are selected fiber length For 27 / 28-34 / 35 mm as raw material, therefore, the world cotton market is based on fiber length grading. The world’s major producers of 38/39 mm fine wool are: Egypt, the Soviet Union, India, Sudan, the United States and Peru. In the recent decade, the output of fine cotton fibers in the Soviet Union increased from 79 kt to 138 kt; in India it increased from 68 kt to 246 kt, an increase of 2.6 times; in the same period, the output of egyptian fine fiber decreased by half from 217 kt To 106 kilotons, which is due to the changes in the world cotton market, the government took
