Plel sleeping bag

It is divided into duck down and goose down. The temperature of goose down is slightly higher than duck down.There are three main indicators of down: the first indicator is filling weight, such as 400 grams of goose down sleeping bag, 1100 grams of duck down sleeping bag. This weight does not mean the weight of the sleeping bagThe amount, down is composed of feather slices and velvet. The feather slices have supportive effects. The warmth mainly comes from fine velvet.The percentage of the contaminated content is expressed that the content of the velvet in the 100 -weight unit in the 100 -weight unit is 80 units.The maximum velvet content of duck down is 85 to 90, and the velvet content of goose down can reach 90 to 95. The 3rd indicator is the expansion of the velvet.Inch, the higher the expansion of the down, the better the warmth of the velvet.Generally, the expansion of domestic duck down is around 450, and the expansion of domestic goose down from 450 to 600.The volume of goose velvet imported from the United States can reach about 95, and the expansion is up to 700 to 800.

Sometimes it is found in the market that is particularly cheap down products, such as 100 yuan a down sleeping bag, 150 yuan a duck down sleeping bag. Such products are generally unsatisfactory.Because there are two indicators that ordinary people cannot test on the spot: oxygen consumption index and cleanliness.The down needs to be cleaned through multiple professional cleaning procedures. Some hawkers make the junior down with a slight cleaning and make it into a finished product. These products cannot be used at all. The simple identification method is to tap the finished product with a wooden stick.I heard that there will be a odor. If it is cleaned, there will be odor in the water.The down itself is a high -quality product. I hope everyone can buy real good products.

As the use time increases warmth, it will slowly reduce until it cannot be used, but they have an advantage that they do not have a down sleeping bag.Once it is wet, it does not keep warm or even negative.The filling density is represented by megs per meter, such as 260 grams/meter Square, 320 grams/meter Square.

Compared with two types of fillings of down and chemical fiber cotton, the degree of down the downween is higher, and the weight can be achieved at the same degree of warmth; the degree of heating of chemical fiber cotton is relatively bottomed, the packaging volume is large, and the compressor is expensive.; Plel humidity will lose almost all the warmth ability, and it is not easy to dry, so it is often used in the strict mountaineering environment to make water and breathable performance for the ingredients of the down sleeping bag. The chemical fiber cotton has a certain water refusal performance.Performance and fast drying speed; the service life of down products is very long, good maintenance can be used for more than 10 years, and the life of chemical fiber cotton Sleeping bags is only 3 or 4 years.
