\n The commonly referred to as down inspection includes down type, down content, down content, down filling, bulkiness, oxygen consumption, cleanliness, odor, and residual fat rate. The meanings of the above indicators are as follows: <\/p>\n
\n Down types: including gray duck down, white duck down, gray goose down, white goose down, etc.; <\/p>\n
\n Down content: refers to the percentage of down and velvet content in feathers and down. The stated value of down content shall not be less than 50%; <\/p>\n
\n Down content: the percentage of down content in feathers and down. Down is the valuable part of down. The higher its content, the better the quality of the product. <\/p>\n
\n Down filling: refers to the total mass of down filled in down clothing. Its measurement method is “first weigh the total mass of the down clothing, then take out the down filling, weigh the remaining part, and the difference between the two masses is Filling amount. \u201d<\/p>\n
\n Fill power: It is an indicator that represents the elasticity of down feathers. The greater the fill power, the better the warmth retention. <\/p>\n
\n Oxygen consumption: The number of milligrams of oxygen consumed in 100g of sample. Oxygen consumption index \u226410 is considered qualified. If it exceeds, it means that the down washing process is not standardized enough, which will cause bacterial reproduction and is harmful to human health. <\/p>\n
\n Cleanliness: Water is used as a carrier, and the tiny dust particles contained in the down are transferred into the water through vibration. These tiny dust particles are suspended in the water, and then an instrument is used to measure the transparency of the water quality to determine the cleanliness of the down. If the cleanliness is \u2265450mm, it is qualified. On the contrary, it does not meet the index requirements, indicating that there are many impurities in the down, which can easily cause various bacteria to be absorbed into the down, which will also have an adverse effect on human health. <\/p>\n
\n Odor: Odor is divided into four levels according to its strength: 0 (no odor), 1 (very weak), 2 (weak), and 3 (obvious). Only when the olfactory judgment reaches a conclusion greater than level 2, the sample to be tested can be judged as Unqualified. If the odor exceeds the standard specification, it means there is a problem with the washing during the processing of washed down. Down jackets can easily cause deterioration during wearing and storage, affecting the environment and human health. <\/p>\n
\n Residual fat rate: Down is a kind of protein fiber. There will be a small amount of fat on the velvet of down. In the down industry, it is called the residual fat rate. If the residual fat rate is high, down products will have difficulties. The smell. The requirement for residual fat rate in the GB\/T14272-2011 standard is no higher than 1.3%. <\/p>\n
