翻译：棉花的分类及用途：根据纤维的长度和外观，棉花可分成3大类：第一类纤维细长（长度在2.5至6.5厘米范围内），有光泽，包括品质极佳的海岛棉、埃及棉和皮马棉等；长绒棉产量低，费工多，价格昂贵，主要用于高级布料、棉纱和针织品。第二类包括一般中等长度的棉花（长度约1.3至3.3厘米）；第三类为纤维粗短的棉花（长度约1至2.5厘米）用来制造地毯、棉毯和价格低廉的织物，或与其他纤维混纺。棉花是世界上最主要的农作物之一，产量高，生产成本低。棉花能制成各种规格的织物。棉织物坚牢耐磨，能洗涤并在高温下熨烫。棉布吸湿和脱湿快速而使穿着舒适。棉花的主副产品都有较高的利用价值，正如前人所说“棉花全身都是宝”。它既是最重要的纤维作物，又是重要的油料作物，也是含高蛋白的粮食作物，还是纺织、精细化工原料和重要的战略物资。因此必须努力使棉花增产，搞好综合利用，增产增值，以增加棉农收入和满足国民经济发展多方面的需要。
