优质棉是指适合国内外纺织需要,外观和内在品质都好的原棉。一般包括成熟度、色泽、长度、强度、细度、断裂长度等。随着棉纺织工艺的迅速发展以及化纤混纺的需要,棉纺工业对棉纤维品质要求越来越高,特别是气流纺纱的兴起,使棉纤维特性的三项指标次序发生了变化,由原来的长度、强度、细度(适合环绽纺纱)变成为强度、细度、长度;并重视棉纤维品质的各项物理性能在纱支强力上的综合表现。为了给棉纺织工业提供优质原料,以生产出优质的纺织品,积极生产国内外产销对路的优质棉,是当前棉花生产面临的重要任务。
High-quality cotton is suitable for domestic and international textile needs, appearance and inherent quality are good raw cotton. Generally include maturity, color, length, strength, fineness, length of fracture and so on. With the rapid development of cotton textile technology and the need of chemical fiber blending, the cotton textile industry demands higher and higher quality of cotton fiber, especially the rise of air spinning, so that the order of the three indexes of cotton fiber characteristics has changed. Length, strength, fineness (suitable for ring-spun yarn) into strength, fineness, length; and emphasis on the quality of cotton fiber physical performance in yarn yarn on the overall performance. In order to provide the cotton textile industry with high-quality raw materials to produce high-quality textiles and actively produce high-quality cotton both at home and abroad for its production and sales, it is an important task facing the current cotton production.
