How to store cotton Precautions 20

1. The warehouse of cotton storage should do a good job of fire prevention, ventilation, moisture-proof, mildew prevention and other measures, especially fire prevention, cotton reserves are generally special fire prevention units, and to have convenient transportation, cotton should be stacked and stored, cotton stacks should be laid under the foundation, sleepers or stones.

2. When stacking, the bag should be placed flat, the upper and lower layers should be cross-pressed, the necessary passage should be set aside between the stack and the stack, the warehouse should be equipped with a thermometer and a hygrometer, check the warehouse every day and measure the temperature and humidity, if it is stored outside the warehouse to cover the tarpaulin.

1. Storage method of cotton quilt: When the quilt is not used for a long time, please place it in a dry place or seal it with a good plastic bag after drying, so that the quilt will not be damp when used in the second year.

2. When storing, the lower half of the cabinet is more likely to get moisture than the upper half, in order to prevent moisture, it is better to put the quilt on the upper layer of the cabinet, and the lower layer can be placed with a more moisture-resistant quilt.

1. The opened cotton should be dried, protected from light, and sealed for storage. Cotton is generally stored in the cotton friends of the Liang industry, and there are two kinds of cotton reserve warehouses in China: brick and concrete warehouses and steel warehouses.

2. The general temperature in the warehouse should be kept below 30, the maximum shall not exceed 35, the relative humidity shall not exceed 70, and the moisture content of cotton in storage shall not exceed 10. Cotton has a long shelf life under normal storage conditions, but because cotton contains a certain amount of moisture, in the case of high temperature, especially when the temperature exceeds 35, the color may change and natural variation, which will affect the grade of cotton.

Cotton is good to preserve.

Cotton can be used for 40 years as long as it is not damp or moldy. Cotton in the adapted environment, ensure that the dog days are taken out and exposed to the sun several times a year, so that it can be stored for 50 years, be careful not to let it be damp, insects, when drying the quilt, it is best to use a wooden stick to beat one side evenly, so that you can better dry the quilt.

Cotton quilts cannot be washed directly, in which case the cotton will be piled up. The quilt should be disassembled, wash the quilt surface separately, cotton generally does not have to be processed, if the time is too long, but you don't want to change it, you can find a "play cotton" help.

I also saw it on a Japanese show, fill the bath with about half of the water, put washing powder or something in the water, then soak the quilt in it, step on the quilt with your feet, step on the quilt for a while, take out the quilt, change the water, and then put the quilt in it, step on it again, and repeat it 3 times, step on the quilt clean, and dry it in a place that is not exposed to direct sunlight but has good ventilation.

Daily cleaning and maintenance methods of quilts.

1. Avoid vigorous rubbing during washing.

2. Choose neutral detergents, try not to use alkaline detergents (such as laundry detergent, soap), alkaline detergents will hydrolyze some dyes and fall off from the clothes.

3. Wash with immersion to shorten the soaking time.

4. Avoid sun exposure.

6. If there are local stains on the clothes, you can use the "dry clothes pre-coating method": when the clothes are dry, apply the special laundry detergent for hand washing to the stains, gently rub the stains after 5 minutes, and then wash the clothes regularly. If the color of the clothing fades, it is recommended to try it in a hidden place of the clothing first, and then use this method without color difference.

1. Harvest cotton in a timely manner, if the cotton fiber is picked too early, the cotton fiber is not fully mature, and the yield and quality are reduced; If the cotton wool is picked too late, the cotton wool will be exposed to the wind and sun, which will reduce the fiber tensile force, the color will be polluted, and the cotton quality will also be reduced.

2. Prevent rain After the mature cotton wool encounters rain, the pigments of the cotton husk and cotton leaves will pollute the cotton, making the white cotton appear red, yellow, and gray spots. If it rains, it will also cause mildew and deterioration. Therefore, it is important to stay on top of the weather changes.

3. When picking cotton, it is necessary to pick good flowers, stiff cotton, and landed cotton separately, dry them separately, store them separately, and store them separately, and they cannot be mixed together in order to grade them.

Cotton from the end of the flocculation to the end of the harvest, generally takes 60 70 days, so it must be harvested multiple times, the time to harvest flowers in a timely manner is generally 7 days after the cracking of cotton bolls is good, and the following requirements are generally required to harvest flowers:

1. Flower collection technology: mainly take the "three nets" and "five points" flower collection method. "Three nets" refers to the harvest of flowers, the plant is clean, the shell is clean, the ground is clean, "five points" refers to the picking, drying, storage, rolling, selling, picking cotton, to pick good flowers, stiff cotton, cotton on the ground separately picking, separate drying, separate storage, can not be mixed together, in order to grade **.

2. Pick at the right time. After cotton spitting, it is generally picked every 5 7 days, if it is picked too early, the cotton fiber is not fully mature, and the yield and quality are reduced; If the cotton wool is picked too late, the cotton wool will be exposed to the wind and sun, which will reduce the fiber pull, the color will be polluted, and the cotton quality will also be reduced.

3. Prevent rain. After the mature cotton wool encounters rain, the pigment of the cotton shell, cotton leaves, and wrapping leaves will pollute the cotton fibers, so that the white cotton fibers appear yellow, red, and gray spots, and if they encounter rain, they will also cause mildew and deterioration, so we must keep abreast of weather changes, pay attention to the weather forecast, and pick cotton before the rain.

4. Spraying to ripen and mature. In the later stage of cotton spitting, the basic mature green bell is matured with pesticides, so that it can harvest flowers in advance, which can not only reduce the harm of autumn rain, increase the quality of cotton by more than 20%, but also pull out the stalks for 5 7 days in advance, which is conducive to the sowing of small spring crops.
