Newly bought cotton sleeves are best placed under the cover or as a tweezers for one or two weeks to make the fibers of the cotton sleeves compact; then use a thick needle to tie a few lines and fix it for reuse. For the old net sleeve that has been used, it is found that there is a part of the yarn unloading, and the thick needle thread is used for the backing and then used.
When drying the cotton cover, it is best to lay the net cover on the wooden board and flatten it on both sides. After the sun is finished, tap it with small rattan or bamboo sticks and bamboo pieces, which can shake off the dust and loosen the cotton, which enhances its heat resistance and cold resistance. It is best not to hang on a bamboo pole or rope to avoid pulling the net. The drying time should not be too long, because cotton itself is rich in natural oils. If the drying time is too long or the time is too long, the oil will be dried and aged, which will affect its adhesion and heat preservation performance.
The cotton cover should be sun-dried when not in use. It is best to put it in a plastic bag and wrap it in thick paper and store it in the cabinet to protect it from moisture.
