At present, some application stores in the market sell the down jacket industry filled with polyester fiber as a natural down jacket. Some corporate customers mistakenly think that duck down is polyester fiber. In fact, they are products that have nothing to do with each other in two ways.
Polyester fiber is a product of chemical technology, however, duck down is a natural product, and duck down is completely different from polyester fiber.
1. Duck down is a kind of reed flower-like down, which grows in the abdominal cavity of ducks. It is very soft and lumpy. Because duck down is a kind of animal protein fiber, there are countless triangular thin vents on the duck down ball fiber, which expands with the change of temperature, which leads to the versatility of temperature control.
Digest and absorb the body to release body fluid heat, and isolate the outside cold air from invading.
2. Polyester fabric is also called "polyester fabric". It is a synthetic research fiber that can be obtained by spinning polyester through an organic combination chemical dibasic acid and ethylene glycol as polymerization.
Known collectively as PET fibers, it was invented in 1941 and is a synthetic nanofiber today.
From the analysis of various inspection results, duck down is one level higher than polyester fiber. As a raw material for keeping warm, duck down's economic value is higher than other raw materials.
