Several Important Indexes Of Down Jacket

Cashmere content: percentage of velvet and velvet in feather and down.

Cashmere content: percentage of velvet in feather and down.

The higher the cashmere content is.

The higher the bulkiness, the better the warmth retention effect.

The greater the density of the filler, the greater the amount of heat lost through the filler fiber conduction. The more the material is, the more warm the down garment is.

Improving the fluffiness of down filling material is the key to improve the thermal insulation property of down products.

Fluffiness: the degree of elasticity of feathers and down.

Bulkiness refers to the volume of a certain quality feather and down sample under constant pressure, which is used to measure the quality of feather washing, drying and preservation. It is used to measure the soft swelling degree and heat insulation ability of down products.

The bulky degree affects the warmth retention performance, and the higher the bulkiness of the down pile, the more the eiderdown can be fixed and the larger the air layer is for insulation and heat insulation.

Foreign standards: a certain condition of each ounce (30 grams) down the volume of cubic inch value.

If the space of one ounce of eiderdown is 600 cubic inches, the feather is 600.

Cleanliness: indicating the cleanliness of feather and down.

Feather cleaning is an important index in the down inspection. It shows the contents of impurities, dust and free organic matter in the down.

Cleaning down products and their products will cause allergic reactions, asthma and other diseases, which will cause serious harm to human health.

GB/T 14272-2011 eiderdown

The standard stipulates that the cleanliness >450mm is qualified.

Oxygen consumption: milligram number of oxygen consumed in 100g down (feather) samples.

The amount of oxygen consumed in eiderdown is related to the microorganisms in feathers and down. It reflects the amount of dissolved oxygen in the water consumed by the aerobic microorganism.

The oxygen consumption <10mg/lOOg is qualified, and if the oxygen consumption is below 10mg/100g, no microorganism is required.
