Down Footprint System
DF ISSUEs
Feather and down, as by-product of the food processing industry, are primarily about 80% sourced in China and largely come from scale industrialized farms or collecting system of small scale farms in European countries.
Functional Down
For centuries, down has remained synonymous with being a light and warm material used for thermal insulation and filling for clothing and bedding. With the increasing popularity of the outdoor leisure market, however, the demand for functional clothing has increased dramatically.
As a filling material, down has also evolved from its original role of thermal insulation into a primary component of different types of functional clothing.
The Basic Qualities of Down
Feather and down materials are a type of agricultural waste which must be carefully washed to remove excess blood, oil, fat, and dust before being subjected to drying and sterilization at high temperatures to remove harmful microorganisms in order to achieve clean and fluffy thermal insulating down materials.
Wastewater Treatment Processing for Down
In response to the requirements of the international markets for the quality of down, the down materials must be fine washed over 6 to 7 cycles with an appropriate refining agent.
Environmental Issues: Overview of Hazardous Substances
In response to the requirements of the international markets for the quality of down, the down materials must be fine washed over 6 to 7 cycles with an appropriate refining agent. Thus, down washing consumes a significant amount of water.
