Yarn hundred meters weight coefficient of variation represents the yarn between long term weight irregularity. Yarn hundred meters of the size of the weight coefficient of variation, directly affect the broken ends of yarn strength, yarn process, fabric appearance, weaving technology, etc. , to a great extent, reflects the level in the process of production quality control. The influencing factors of yarn hundred meters weight coefficient of variation is more, from the device type differences to the operation of the machinist level, from the raw material of the cotton assorting scheme to the stability of temperature and humidity, each process does not affect yarn hundred meters weight coefficient of variation. So, yarn hundred meters weight coefficient of variation of how to control? Yarn hundred meters weight coefficient of variation of 1 to strengthen the process control measures the temperature and humidity of the temperature and humidity control to strengthen the process control, especially pure flower and moisture regain of the article and the process is stable and is helpful to further stable lap weight and cooked a weight control, minimize control deviation, prevent the occurrence of the second kind of circumstance. Mainly is the pure flower lap moisture regain control and stability, is advantageous to the weight unevenness of control. 2 strengthen the pure flower lap evenness and lap weight strengthen pure flower control of the lap evenness and lap weight control ( The irregularity inside and outside the irregularity of systems and control) , and the first 1 m the weight of the control volume. Strictly random examination, to prevent unqualified products into the next working procedure. The weight of the lap to lap moisture regain weight lap of the combination of small fluctuations. 3 strengthening the noil carding process control combed cotton noil unified index for process control. Try to adjust the process to make noil differences in & plusmn; 1. Within the scope of 0%. 4 well machinist operating standards machinist in each process operating standards, improve the qualified rate of lap joint, to strengthen the inspection and put in place. Especially to strengthen the collocation of article and process raw weight work, it is forbidden to fraud. 5 good control of roving elongation control of the machine rooms, front row roving processes between roving roving elongation, narrowing the differences between the between Taiwan and the front row. 6 to strengthen the laboratory for weight deviation control in each process to strengthen the laboratory for weight deviation control in each process, especially the article 2 and the weight deviation control work. Adopt single deviation and total deviation method to adjust the change gear, attention to two or morethings draft consistency during adjustment. 7 narrowing the difference of spinning process model under the condition of the spinning process if the space allows, try to make the same variety, with the same type yarn. When there is no guarantee that the same model, but to make two kinds of models of the draft agreement, to narrowing the difference of spinning process models, to achieve the purpose of controlling yarn hundred meters weight coefficient of variation.
