Cause of occurrence and characteristics of the material
Bio-down dupont sorona was created from a biopolymer by two companies ZM Thinsulate, DuPont. The invention was discovered by accident. During the production process, a substance for adhesive tape was prepared. The synthetic material appeared due to errors. The quality of raw materials is constantly improving. It began to be used in the manufacture of outerwear.
When wondering what bio-down is, you need to know that it is an insulation material that contains constantly renewable natural elements. They undergo special processing. A patent has been received for the production process, which meets established standards.
The material is environmentally friendly. Regularly renews itself in the environment. The technological process is unique. During manufacturing, it was possible to reduce the consumption of extracted fuel. Energy consumption for the formation of bio-fluff is 30% lower compared to nylon. The amount of gases released is -63% less. For the results, the manufacturer was awarded a certificate.
DuPont Sorona insulation - what is it?
The American chemical company DuPont, one of the largest in the world, was founded in 1802 and was initially associated with the military industry.
The founder of the company, Elether Irene Dupont de Nemours, created a gunpowder production plant, which later began to supply the US military-industrial complex with explosives, chemicals and incendiaries. By-products of their developments in the 20th century included Teflon, and subsequently bulletproof Kevlar. For more than a century, DuPont has been producing innovative textiles, innovative fibers and is on the cusp of making the transition to 100% bio-based materials. Sorona is a division of DuPont Corporation that specializes in producing renewable raw materials that help reduce dependence on petroleum resources and reduce greenhouse gas emissions. 37% of the polymer is produced using annually renewable plant components. The revolutionary new Bio-PDO compound transforms a chemical process into an environmentally efficient biological process. Energy consumption in Sorona production is reduced by 40% and greenhouse gas emissions by 56%. The latest biological polymers are widely used in the production of household and commercial carpets, clothing, and the automotive industry. Product life cycle assessments from raw materials to final products show that Sorona is much more environmentally sustainable in all aspects than petroleum- and polyamide-based materials such as nylon.
Through decades of research and asking the right questions, DuPont scientists have found a way to produce PDO—a versatile building block with infinite potential—using a biological process that will have a global impact.
Sorona not only ensures the durability and recyclability of the final product, but also has many properties that help reduce the adverse environmental impact at all stages of the life cycle.
Sorona's renewable fibers provide a superior combination of performance for sustainable clothing. The fabrics of the material are very soft, extremely durable and dry quickly, and also stretch well and always retain their shape. Additionally, manufacturers using Sorona fiber can dye clothing at lower temperatures, achieving excellent color fastness, which undoubtedly has a positive impact on the environment.
Another notable feature is that Sorona material does not use heavy metal catalysts during the polymerization process and that it is inherently stain resistant without requiring any additional chemical treatment. This is undoubtedly a great advantage and is used by clothing manufacturers such as Wellensteyn. Of course, consumers also like this practicality.
Apparel manufacturers and designers take advantage of Sorona's versatility to enhance the performance of other fibers, natural or synthetic, such as cotton, linen, wool, nylon, polyester. Cotton and linen materials are very light and comfortable, while wool-patterned fabrics are soft and durable.
Sorona is a perfect material that combines environmental protection and functionality in an unprecedented way, which can be called a comprehensive breakthrough in science.
Based on the Sorona polymer, DuPont and Haixing Material Technology corporations have developed and patented an insulation called Sustans or, as it is called in Russian, bio-down. This insulation has incredible thermal insulation properties and can be used in the most severe climatic conditions with low winter temperatures.
High-tech bio-down has all the best properties of the Sorona material, and down jackets based on it are light, practical and durable. Sustans has numerous awards as the first bio-based material and exemplifies the latest advances in biotechnology and innovative fibers.
Main characteristics
Buyers are often interested in whether bio-down is warm or not? The insulation is characterized by excellent thermal insulation performance.
There are both pros and cons to artificial down in jackets. After washing, the product dries completely in just a few hours. While winter outerwear with other types of insulation takes much longer to dry.
Bio-down insulation has other advantages:
- Long service period.
- Harmless. Does not cause allergic reactions.
- A light weight. The filler does not restrict body movements.
- The material does not absorb external odors.
- Plastic. Does not become thinner over time, creases do not appear.
- Can be washed in an automatic machine. Things do not change shape and are resistant to compaction and rolling.
- Fibers do not show through seams.
- Moisture resistant.
Useful
For those who are interested, what temperature is bio-down designed for? Answer, clothes can be worn at minus 40 degrees Celsius.
However, artificial down also has disadvantages:
- you can overheat in clothes;
- there are problems with removing sweat from the body;
- static electricity accumulates;
- the price is higher than that of natural analogues;
- raw materials are deformed when exposed to high temperatures near heaters or open fire.
Despite some disadvantages, down jackets with artificial down can be worn in unfavorable climatic conditions - severe frost or windy weather.
Why is Sustans better than other natural and synthetic fillers?
- Sustans. New technologies and materials in the production of children's jackets
Compared to natural filler, in addition to being lightweight, bio-down is more comfortable to wear and does not prick. Nevertheless, at the same density, organic material has superior thermal insulation properties.
Synthetics are also valued for their lightness, but they do not retain heat well, become deformed after washing and crawl through holes in the outer fabric.
Artificial down, in turn, is too soft, quickly loses its shape and can leak through the outer layer of the material.
Bio-down and eco-down: which is better?
Many housewives are also interested in the questions of what is bio-down in a down jacket or what is eco-down? The first one is a soft and fluffy raw material with a biological base. It has a spherical and three-dimensional structure, reminiscent of real fluff. Main qualities: breathability, elasticity. Reminds me of silk. 50% more warm than natural down.
Purpose and scope
Bio-down in outerwear at low temperatures performs a protective function against frost and wind. The filler is used in the manufacture of:
- equipment for fishermen and hunters;
- equipment;
- travel sleeping bags and sports accessories;
- casual outerwear (pants, jackets);
- insulated suits for snowboarding and skiing.
The models are comfortable to move in. Thanks to the lightness and plasticity of the raw materials, manufacturers create attractive and stylish models.
Reviews about biopooh insulation
Since this material is relatively new, not all potential buyers are familiar with its properties. There are also quite a few reviews about it, but they are all extremely positive. Buyers liked biodown in outerwear as follows:
- it is soft and light, it is convenient to engage in active sports in such products;
- in such clothes it is not cold even at -20 ° C;

Wash
How to wash bio-down so that the material does not deform? Before washing, rub off heavily soiled areas and stains with plain soap. You should follow the manufacturer's recommendations indicated on the label, which indicate how many degrees the water is heated to, as well as the number of revolutions.
Basic rules for machine washing regular bio-down clothing:
- the temperature regime is set no higher than 40 degrees Celsius;
- It is advisable to use the additional rinse function;
- the number of revolutions is no more than 600;
- to avoid white marks, use special liquid detergents;
- When rinsing, it is better to add conditioner to soften the material and extend its service life.
Housewives who are wondering whether it is possible to wash large items need to know that hand washing is allowed, since they do not fit in the machine. You should also follow the following recommendations:
- Contaminated areas are cleaned with a brush;
- clothes are washed so that the filling gets wet evenly;
- pour non-hot water into the container;
- rinse clothes at least twice.
When washing bio-down in outerwear, the temperature is set to the same as when washing in a washing machine - no higher than 40 degrees Celsius.
Useful
In order to dry clothes from a bio-down jacket or down jacket, it is laid out on a surface in a horizontal position. It is advisable to place a thick natural fabric (towel) where excess water will drain. The material should not fade. The products are periodically turned over. Beat the dried item well to evenly distribute the fiber in the middle.
After washing, things need to be dried in natural conditions. You can do this outdoors or in a ventilated area. Do not leave directly in the sun, too close to a heater or open fire.
