in the formula: a isFruit of Chinese wolfberryIs the actual oiling rate of the DTY yarn (10),
Figure 986214DEST_PATH_IMAGE008
is the oiling coefficient, T, of the DTY yarn (10)1Is the temperature of the oil, t1For the limit time of the DTY (10), the oiling rate of the DTY (10) is regarded as more than 30% when the limit time is exceeded, the oiling rate exceeds the standard at the moment, the spinning can not be carried out, and the actual requirements of the DTY (10) are as follows:
Figure 271702DEST_PATH_IMAGE009
in the formula: a isNeed toIn order to meet the requirement of the oiling rate,
Figure 743134DEST_PATH_IMAGE010
to the coefficient of cohesion, T2For external temperature, the actual oil rate should equal the oil rate demand, and then derive:

Figure 260146DEST_PATH_IMAGE012
。
2. the intelligent detection device for the static DTY textile yarns, according to claim 1, is characterized in that: in the step S4, when
Figure 32929DEST_PATH_IMAGE013
When the stirring unit is started to start stirring, n1The volume constant is adopted, namely when the addition amount of the smoothing agent is larger than or equal to the volume constant, a certain amount of smoothing agent is introduced and the stirring unit is started, after the smoothing agent is added, the DTY (10) needs to change the viscosity of the oil due to external factors and the required viscosity is increased, the material conveying is stopped, the oil in the upper oil tank (1) is completely discharged, the oil is re-injected, then the smoothing agent is introduced again, and the viscosity of the oil is adjusted to the specified value.
3. The intelligent detection device for the static DTY textile yarns, according to claim 2, is characterized in that: the inner side of the upper oil tank (1) is provided with a stainless steel coating.
