The role of the main process parameters of the texturing machine

What role do the main process parameters of the texturing machine play in the production process of texturing wire? Describe their function.

1: The draw ratio is an important parameter for the post-processing of POY. With the increase of the draw ratio of POY yarn, the strength of the DTY yarn will increase accordingly, but if the draw ratio is too high, DTY is prone to filaments, so a reasonable stretching must be selected. Multiples can make DTY fiber achieve the desired effect.

2: The acceleration speed is that with the increase of speed, the crimp rate and stability will increase accordingly; the residence time of fibers in the hot box will be shortened accordingly, and the crystallinity of DTY will decrease.

3: The effect of deformation temperature The temperature of the first hot box and the second hot box is determined according to the physical index of POY measured in advance. If the POY stretches too long, the temperature of the first hot box may be relatively high; if the POY stretches too short, the first hot box temperature may be relatively low. The temperature of the first hot box for fine denier filaments can be lower. If the temperature is set too high, filaments will be produced. If the temperature is too low, the dyeing uniformity will decrease. The temperature of the first hot box for coarse denier silk can be higher. If the temperature is set too low, tight spots will occur. If the temperature is too low, the dyeing uniformity will also decrease.

4: Function of false twisting tension Only by setting the appropriate D/Y value can the appropriate false twisting tension be obtained, and the D/Y value can be set according to the material and combination of the friction discs. Excessive false-twist tension is not good for the processing of fine denier yarn, and it is easy to break. Therefore, a relatively low false-twist tension is selected when processing fine denier yarn. Too small false-twist tension is also unfavorable for the processing of coarse denier yarn, and the false-twist effect is likely to be poor. Therefore, a relatively high false-twist tension is selected when processing coarse denier yarn. The empirical data of processing is T2/T1=0.7±0.1. The specific DTY product variety should be set through constant exploration to set the false twist tension value.

5: The function of the winding tension is to obtain a good package effect and avoid the difficulty of unwinding during the post-processing of the DTY silk. The DTY silk cake is too large or too small to affect the post-processing performance.
