What effect does temperature and humidity have on cotton? It’s important!

Cotton is a very important crop with great economic benefits in China. The main component of cotton is cellulose, and cotton fiber is the main raw material of the textile industry, accounting for about 55% of China’s textile raw material at present. Cotton is a kind of heat loving, good light, drought resistance, avoid stains of cash crop, suitable for growing in loose, deep soil, generally planted in warm, sunny areas. China’s cotton is mainly grown in the Jianghuai Plain, Jianghan Plain, cotton areas in southern Xinjiang, North China Plain, Northwest Shandong Plain, North Henan Plain, the lower reaches of the Yangtze River coastal plain.

Temperature and humidity have an important effect on the color, quality and morphology of cotton, mainly reflected in the effect on the color and quality of cotton. Cotton moisture regain is the percentage of moisture in cotton relative to dry fiber weight. We all know that in humid conditions, microorganisms are easy to grow and reproduce, when the moisture return rate is greater than 10%, the relative humidity of the air is higher than 70%, the cellulase and acid secreted by microorganisms will lead to mildew deterioration and discoloration of cotton fiber. If the temperature and humidity are too high, microbes are very active, the color of cotton fiber is often destroyed to varying degrees, fiber photorefractive index decreased, the grade also decreased. Therefore, the temperature and humidity will have a very important effect on cotton, cotton is suitable for storage in a relatively dry place, which can not only guarantee the color of cotton for a long time, but also ensure the good quality of cotton.


Therefore, we need to detect the temperature and humidity of the cotton storage environment, with the help of some temperature and humidity measurement instruments. There are many kinds of temperature and humidity instruments, and the measurement accuracy is also different. Choosing the appropriate instrument is the basic condition to improve the accuracy of temperature and humidity observation records. At present, the main instruments commonly used are dry and wet spherometer, ventilated hygrometer, temperature and humidity meter, temperature and humidity recorder. The temperature and humidity recorder is an instrument that records the temperature and humidity parameters and automatically stores data at the time interval set by the user. It can be connected to the PC end for data operation and analysis.

USB temperature and humidity recorder -DSC_7862-1Hengko wireless temperature and humidity data logger, it is a new generation of industrial data recording products, it integrates the advanced chip technology, used the high-precision sensor, the temperature and humidity measurement, equipped with intelligent data analysis and management software, to provide users with a long time, temperature and humidity measurement, record, alarm, analysis, and so on, satisfy the customer different application requirements in the temperature and humidity sensitive situations. The data logger can store 64000 data, the largest provide USB transmission interface, users only need to insert the data logger computer USB port, and then through matching SmartLogger software can and it is connected to the data logger for management and all kinds of operation, set up, download the data on the recorder to the computer, and analyze the data and generate the data curve and output statements and reports.

Temperature and humidity recorder -DSC 7083If you want to check the temperature and humidity on a regular basis, you can choose a hand-held temperature and humidity sensor with a different temperature and humidity probe that can measure the temperature and humidity in the air or in the cotton pile. Hengko offers a variety of optional probes for different applications. The replaceable probe facilitates easy disassembly or reassembly at any time. Probe shell made of stainless steel, good corrosion resistance, high strength is not easy to damage, pore size range 0.1-120 micron, waterproof at the same time, but also breathable for measurement of temperature and humidity data.

There are many instruments for measuring temperature and humidity. It is mainly to choose different measuring instruments according to the actual situation, such as the accuracy and use range of the measurement. Choose the measurement accuracy of the most suitable data, but also for their timely adjustment to take measures to protect the quality of cotton to avoid deterioration of the situation.
