Synthetic insulation is essentially polyester threading that is molded into long, single threads or short staples to mimic down clusters. Thinner and lighter threads fill voids and trap warm air more effectively. Unlike down, synthetic insulation is water-resistant and will still provide some warmth if it gets wet.
Is down warm when wet?
So now we know down is warm but doesn't do well in wet or humid conditions. Enter synthetic insulation. Synthetic insulation is designed to replicate the qualities of down, but retain them even when wet. These ultrafine fibers trap warmth in air pockets, providing great warmth… though not quite as good as down.
The feathers on geese or ducks are the outer covering of the bird. They have quills, repel water, and make it possible for the animal to fly. Down lies beneath this protective covering – usually on the belly of a bird - and is light and fluffy. It provides the insulation birds need to keep warm.
Still, the practice of live-plucking ducks and geese does reportedly live on at factory farms in countries such as China, Poland and in feather powerhouse Hungary, where PETA estimates that 50 percent of down and 40 to 45 percent of feathers have been live-plucked by experienced “rippers” who are paid piece-rate.
Puffer jackets, also called quilted jackets, have a signature quilted design with sections that are "puffy" between the stitching. They are filled with down insulation or synthetic fibers, both of which can provide a high level of warmth depending on how well they are made and the quality of the synthetic fibers.
Cotton is a good conductor of heat, this means that it will quickly transfer the heat away from the body. This is why cotton is the fibre of choice for hot summers! Polyester comes in several forms and most of them are warmer than cotton. Both fabrics can be warm; polyester is warmest as polyester fleece.
Down Pillows. The undercoating of a bird's feathers is called down. More specifically, it's the bottom, fluffy part of a bird's feather. Down holds its loft up to 3 times longer than synthetic alternatives and is very soft. A real down pillow contains down only — no feathers.
Down Insulation. You might not believe us, but down is not made from feathers. Down insulation is made from goose or duck plumage – the lofty, fluffy stuff underneath the feathers. It is an undercoating, or a natural midlayer. Nature's best insulation, down creates high-loft clusters that trap air and body heat.
Down pillows are a less noisy and more comfortable alternative to feather pillows, which are filled with 90 to 95 percent feathers. However, down pillows have both benefits and drawbacks when compared to synthetics such as "down alternative" and polyester fill pillows.
Down comforters are made from the light, fluffy clusters and plumules that come from beneath the feathers of ducks and geese. The quality of down can be determined by the fill power or loft. Down alternative comforters are great options for anyone allergic to down feathers or for anyone on a stricter budget.
Since birds like ducks and geese are bred in large groups for the production of meat and foie gras, "harvesting" their feathers is a profitable by-product. Feathers are usually removed during the natural moulting cycle of the bird, which is the time when they shed their old feathers and grow new ones, every 6-7 weeks.
Padded jackets are warm winter jackets with fur padded inside it order to insulate heat where the clothing material is especially made of synthetic fibers. One perfect example is the Parka jacket which is a padded jacket with hoods and warm faux fur for that extra comfort during the cold winter season.
PrimaLoft® is a brand of patented synthetic microfiber thermal insulation material that was developed for the United States Army in the 1980s. PrimaLoft is a registered trademark of PrimaLoft, Inc., the brand's parent company.
Simply put, DriDown™ represents the evolution of down insulation. Regular down is treated with a molecular level polymer to create a hydrophobic finish on each individual down plume. This finish allows DriDown™ to stay dry longer, loft better, and dry faster than untreated down, keeping you warmer in any environment.
Do up all the zips and velcro on the bag, if it has a waterproof shell turn it inside out. Place your sleeping bag in the machine and add a technical cleaner. Regular detergent or softener can damage down sleeping bags. Wash your down sleeping bag at 30° or on a delicate cycle.
Synthetic Cluster Fiber: This synthetic down alternative consists of clusters of synthetic fill, providing a puffy, lofty pillow. Micro Fiber: This lightweight material has down-like softness. It creates a satisfyingly thick surface that is plump and airy.
-Down is a natural product, made from a fluffy layer under the feathers of geese that keeps them warm. -The industry standard for luxury is a high fill power, down pillow. Down-Free. -Synthetic down alternative, made of puffs of polyester provide a cooler sleeping experience than down, which traps and holds heat.
About memory foam pillows. Memory foam, also referred to as visco elastic foam, is foamed polyurethane with additional chemicals which increase its density and viscosity – sounds lovely doesn't it. The foam bubbles or 'cells' are open, effectively creating a matrix through which air can move.
