Cotton is generally stored in the library profession cotton reserves, China's domestic cotton reserve coffers have two kinds of brick and concrete warehouse and steel storage silo. Repository requires convenient transportation, fire protection, ventilation, moisture, mildew, etc., especially fire, cotton repository are super fire units. Generally cotton library stacks should be stored outside the library holds the cover tarpaulin. Under the cotton pad stack to lay the base (sleepers or stones), when stacking packages should lie flat on the lower cross-pressure joints. Should stay out of the necessary channels between the stacks and stacks.

Cotton Reservoir to set up meteorological observation shelter, each of them must be equipped with the Treasury hygrometer. Custodian should check the library every day to measure temperature and humidity, and make a record. According to weather changes and differences in temperature and humidity inside and outside the library, should be taken off ventilation scattered wet or warehouses and other measures timely. General interior temperature should be maintained at below 30 ℃, the maximum should not exceed 35 ℃, relative humidity should not exceed 70%, the moisture content of cotton custody shall not exceed 10%. Cotton under normal storage conditions, a longer shelf life, but because of the cotton contains some water, in the case of high temperatures, especially when the temperature exceeds 35 ℃, the color may vary, a natural variation, thereby affecting the cotton grade.

According to the analysis of experienced storekeeper cotton, natural variability of cotton was "S" shape, which began variation is slow, intermediate and rapid variation over time, over a certain period of time after its mutation rate has slowed. In general, the new cotton (including tidal rate does not exceed 10.5%) in line with the national standard of water placed in the custody of the normal warehouse, before the heat of summer temperature variability is generally not occur naturally, but after the summer season, due to the temperature rise, humidity increases and other factors that may cause the cotton natural variability, so that the new cotton in a cotton annual average down a level, and the higher the grade, the more stable, the lower the grade, the more unstable the quality, the more prone to natural variation.
