The White Dew, as the fifteenth of the 24 solar terms, marks a crucial juncture when autumn transitions from hot to cool. At this time, the temperature drops rapidly, the duration of daylight shortens, and the water vapor in the air condenses into glistening dewdrops upon contact with condensation, presenting a scene of "the night of White Dew and Autumnal Equinox gets cooler one night after another". For Polypropylene spinning machine enterprises, the climate change during the White Dew period has an impact on the stable operation of polypropylene spinning machines and product quality that cannot be ignored.

In terms of temperature control, with the arrival of the White Dew solar term, the temperature difference between day and night increases significantly. The fluctuation of the ambient temperature in the workshop will interfere with the precise temperature control of the polypropylene spinning machine. The temperatures of the spinning box, screw and spinneret need to be flexibly adjusted according to the changes in the external temperature. For instance, in the early morning and at night when the temperature is relatively low, the heating power of the spinning box should be appropriately increased to ensure that the polypropylene raw material can be fully melted, maintaining the stable fluidity of the melt. This is to prevent the increase in melt viscosity due to excessively low temperatures, which may lead to spinning breakage, fuzzles and other conditions, affecting product quality and production efficiency.

Humidity is also a key point to pay attention to during the White Dew period. After the White Dew, the humidity of the air usually rises. Excessively high humidity can cause polypropylene raw materials to absorb moisture, alter their physical properties, and have a negative impact on the spinning process. Enterprises need to enhance the dehumidification management in workshops, turn on dehumidification equipment, and keep the humidity within an appropriate process range. At the same time, it is necessary to closely monitor the storage environment of the raw materials to ensure they are dry and prevent the uniformity and stability of spinning from being affected due to moisture in the raw materials.

From the perspective of equipment maintenance, during the White Dew period, the temperature difference between day and night is large, and the metal parts of the polypropylene spinning machine expand and contract frequently due to heat and cold, which can easily cause the parts to loosen. Enterprises should seize this opportunity to conduct a comprehensive inspection of the spinning machine, tighten the bolts of key parts such as the screw and transmission components, and ensure the smooth operation of the equipment. In addition, it is necessary to check whether the cooling water pipeline has any leakage due to temperature changes, repair the hidden dangers in time, ensure the normal operation of the cooling system, and provide a reliable guarantee for the efficient operation of the spinning machine.

During the special solar term of White Dew, polypropylene filament manufacturing enterprises can only ensure the stability of production and the excellence of product quality by closely monitoring environmental changes, precisely regulating various parameters of Polypropylene spinning machines, and strengthening equipment maintenance and care. They should follow the natural laws and continuously provide high-quality polypropylene filament products to the market.
