目前,原棉品质存在的问题是纤维强度低,成熟度差,纤维长度长而集中,适纺纱支范围小。现就棉花生产品质现状与棉纺工业的矛盾分述于下。 (一)纤维品质指标与棉纺工业的关系纤维长度纤维越长可纺纱支越细;且可提高成纱强力。纤长平均增加1mm,棉纱强力提高5％以上。成熟度成熟差的纤维易形成棉结。影响棉纱的条干和外观, At present, the problems with raw cotton quality are low fiber strength, poor maturity, long fiber length, and low spinning range. Now the status quo on the quality of cotton production and the contradiction between the cotton spinning industry are described below. (A) the relationship between fiber quality indicators and the cotton industry Fiber length The longer the fiber spinning yarn can be thinner; and can increase the yarn strength. Slim an average increase of 1mm, cotton yarn strength increased by 5% or more. Mature maturity of the fiber easy to form neps. Affect the cotton yarn dry and appearance,
