The temperature and humidity of the air have a great influence on the production of textile technology. This is because textile materials (natural fibers and chemical fibers) are mostly hygroscopic or prone to static electricity. Therefore, the control of temperature and humidity in each workshop is the basis to ensure stable improvement of product quality and smooth production.

In practice “stability” is not a simple word. In order to stabilize the product quality, air conditioning in the workshop must be strengthened. When the temperature and humidity of the workshop and the moisture regain of the semi-finished products are suitable for the production process, the air conditioning operation should focus on the stability of temperature and humidity. When the moisture regain rate can not reach the provisions, there are fluctuations in the first place to pay attention to the control and management of temperature and humidity. Therefore, attention should be paid to the following aspects and corresponding measures should be taken.

1) reduce the “day and night difference” and “sub-difference” of temperature and humidity in the workshop, and do a good job in the prevention and regulation of temperature and humidity in the workshop.

2) observe weather changes outside frequently and strictly control the dew point of the machine to achieve the purpose of controlling indoor parameters.

3) when the temperature and humidity of the workshop are affected by outdoor meteorological conditions, corresponding measures should be taken to adjust the air volume, water spraying volume, water temperature of the air conditioning room and the ratio between fresh air and return air to stabilize the dew-point within a certain range.

4) the temperature and humidity of the workshop can be changed and controlled by adjusting the air volume of the outlet or the air volume of the branch duct in the local area of the workshop.

5) master the law of diurnal variation of outdoor air temperature and humidity, stabilize the temperature and humidity of the workshop, reduce fluctuations, so as to stabilize product quality.

6) each shift should coordinate closely to exchange information and establish the overall concept, which is conducive to stable temperature and humidity of the workshop.

Pieces 7) reduce the regional differences of the workshop temperature and humidity, pay close attention to outdoor weather conditions such as wind, wind, sunshine changes timely adjustment, can also be targeted to adjust the size of the air duct exhaust air (to take the measure can also be deliberately increase regional differences, to ensure that the same workshop to the different requirements of temperature and humidity in various processes).

8) the production workshop must be kept in a positive pressure state to avoid the influence of outdoor weather on the temperature and humidity of the workshop, and at the same time to ensure the requirement of fresh air. This not only ensure the smooth progress of production but also ensure the health of the workers.

9) in case of sudden weather change (sudden cold, sudden heat) or thunderstorm, please pay attention to the management of doors and Windows, use more return air, and control the dew point of the machine.

10) adjust the temperature and humidity of the production workshop according to the actual situation of raw cotton to ensure the smooth production and product quality.

11) it is easy to control the temperature and humidity of “one workshop, multiple working procedures” in the production with the method of gradual dehumidification, so as to stabilize the product quality.

12) reasonable use of the return air in the workshop can not only control the temperature and humidity in the workshop, but also achieve the purpose of energy saving.

13) retrofit or completely re-select the air conditioning room that cannot meet the needs of production process, and purchase after economic and technical demonstration. In the selection of modern textile air conditioning development trend – “environmental protection and energy saving” two major themes to choose.

14) to carry out energy-saving transformation to meet the production demand, using new energy-saving fan, stepless speed change and frequency conversion speed change technology.

Practice has proved that the reasonable regulation of temperature and humidity in the workshop can improve the production status of the workshop, so it is essential to grasp the law of the influence of temperature and humidity on the production process, and strengthen its management and control.
