Conclusion is made that the carding roller is the main cause of the aparting degree of fiber,effecting yarn strength,evenness,slubs and snicks.
为了提高转杯纺纱工序的成纱质量,通过大量的试验数据分析,详细讨论了分梳辊、假捻盘、转杯对成纱质量的影响,指出:分梳辊主要影响纤维分离度,从而影响成纱强力、条干和粗、细节;假捻盘具有假捻效应,主要有利于提高动态强力,降低成纱断头,稳定生产,但不利于提高成纱强力;转杯转速与直径的配置是关键,速度、直径和凝聚槽形状直接影响成纱质量。
Using some experimental data of cotton fiber quality to train the network and then forecasting the yarn strength,it can be obtained that using RBF neural network to forecasting yarn strength can overcome the shortcomings,e.
由于多元线性回归模型对棉纤维的品质和成纱质量之间关系预测精度及适应性较差,提出采用径向基函数对BP神经网络进行改进,使用测得的棉纤维品质部分实验数据对网络进行训练,然后对成纱强力进行预测,得出采用改进后的RBF神经网络对纱线强力进行预测,克服了陷入局部极小和运算迭代量大的缺点,有效地提高学习速度,收敛速度加快,训练时间缩短,预测精度提高,能较好地预测纱线的强力。
In order to explain the effect of these structural parameters on yarn strength,experiments and regression analysis are undertaken to investigate the effect of the first nozzle structural parameters on air-jet spun yarn strength.
4 mm,喷射孔数目为4个时,成纱强力最高。
We have found that the relationship between the cotton fiber quality and the yarn strength can be modeled as a gray system.
以棉纤维原料品质与成纱单纱强力所组成的系统为灰色系统,并对这一系统采用灰关联方法进行了分析。
During cotton yarn spinning,the control of the yarn strength mainly depends on cotton blending and operator′s experience and it is impossible to carry out accurate estimation and design of the strength of the forming yarn in advance.
针对纺织生产过程中棉纱单纱强力控制主要采用配棉技术及凭借工程技术人员的经验调节纺纱工艺参数,不能事先对棉纱线的成纱强力进行较为准确的估计和设计的问题。
Fiber convolutions also correlate negatively with such physical measurements as bundle tenacity.
天然转曲对成纱强力可能比对纤维束强力起着更大的直接作用。

"More twist produces stronger yarn; low twist produces softer, shinier yarn."
捻度较大的纱强力好,低捻纱柔软有光泽,高捻产生皱纱。
Assuming the yarns are single spun yarns, the tensile strength of the yarns needs to be improved. At this point, the major strength that the yarns possess is that derived from the twisting of their fibers.
假设使用的是短纤维单纱,纱线的强力需要增加,单纱的强力主要来自对纤维的加捻。
