空气变形纱毛羽的测试方法

突出于纱体表面的零散的弧圈结构形成了空气变形纱的毛羽，其与纱线主体之间的界限模糊，且其毛羽结构和状态在外力作用下极易改变，对检测条件要求较高．通过4种仪器和方法对空气变形纱的毛羽进行了测量，认为EIB（Electronic Inspection Board）和Uster tester 4两种仪器的检测结果与静态投影目测计数法检测结果较为相近：空气变形纱毛羽数量高于同线密度的普通精纺毛纱和精梳棉纱的毛羽数量；空气变形纱的毛羽数量多集中于短毛羽（毛羽长度在1mm以下）区，并且随着毛羽长度增加而急剧减少，呈指数关系，在长毛羽（毛羽长度在2mm以上）区，空气变形纱毛羽数量显著少于短纤维纱．

须条与长丝间距对Sirofil成纱结构性能的影响

分析了Sirofil纺纱过程中“V”形区的动态变化及粗纱须条与长丝间距大小对“V”形区形状和单纱受力的影响,认为间距增大会使“V”形区夹角增大、单纱段长度变长,并以此为依据,保持其他工艺参数不变,改变粗纱与长丝间距大小,试纺Sirofil纱,通过理论分析和实验比较讨论间距大小对Sirofil成纱结构性能的影响。结果表明：随着间距增大,成纱直径系数趋小、毛羽减少、强伸性与条干均呈非单调性变化;综合考虑成纱结构和性能,在其他参数相同时,Sirofil最佳成纱间距为12～16mm。

Prediction of Rotor Spun Yarn Strength Using Adaptive Neuro-fuzzy Inference System and Linear Multiple Regression Methods

This paper presents a comparison study of two models for predicting the strength of rotor spun cotton yarns from fiber properties. The adaptive neuro-fuzzy system inference （ANFIS） and Multiple Linear Regression models are used to predict the rotor spun yarn strength. Fiber properties and yam count are used as inputs to train the two models and the count-strength-product （CSP） was the targel. The predictive performances of the two models are estimated and compared. We found that the ANFIS has a better predictive power in comparison with linear multiple regression model. The impact of each fiber property is also illustrated.
