When washing down products, first put them in clean water and soak them for about half an hour, and then gently rub them with your hands to let them absorb enough moisture to eliminate dust stuck to the down. Then pour out the water and add an appropriate amount of low-foam neutral detergent. The amount of dissolution is based on the immersion of down products. After about 20 minutes, gently brush the down products with a soft brush, and then wash with water. During the cleaning process, fold the down product and press the moisture dry. Do not use hand twist or rub it with a washboard, otherwise it will damage the down fiber and affect the warmth. When drying, you can spread the down products on the flat plate, and then cover them with a clean cloth after drying, and expose them to the sun, but the time should not be too long. After drying, pat the down with your hands, flip the side and dry for a while, and wait for thorough drying.
If you want to whiten the white cloth (including native cloth or muslin), you can squeeze out the juice and cold water from the grey vegetable leaves, soak the cloth inside, take it out after half an hour, and dry it with clean water, and the cloth color will become white.
In recent years, light and comfortable down products have always been the favorite cold-proof product for consumers. So, how can we buy high-quality down products?
Sniff: That is, use your nose to smell whether the down product has a duck smell. Down products that have been strictly disinfected cannot smell the fishy smell of duck. If they can smell the fishy smell, it means that the down disinfection is unqualified and insect-bearing and moldy will easily occur in the future.
Touch: Use your hand to touch the down stuffed in the down product to find out how much it contains. Down products with high down content feel soft and comfortable to touch, making it difficult to find a hard stalk.
Phone: Use your hand to pat down products to see if there are any dust and impurities. If you pat down products with your hands, dust will indicate that the down is not washed clean or mixed with impurities.
Press: Press down the down product with your hands to see if it can bounce naturally. If it can pop up naturally, it means the quality is good, otherwise the quality is poor.
After identifying the internal quality of down products through the above methods, it is also necessary to identify them from the appearance. First, you must identify the manufacturer's trademark. Secondly, check the appearance quality. You should carefully check whether the sewing is fine, whether the needle spacing is uniform, whether there is color difference in the fabric, whether the feathers are woolly, etc.
