What's in a duvet cover?

1. Overview of Main Filling Materials

The core filling of a duvet cover is primarily goose or duck down. The down on the abdomen of these animals is reed-like and is an animal-derived protein fiber. Compared to plant-based or synthetic fibers like cotton and polyester, the porous structure of the down traps more air, creating a natural insulation layer and significantly improving thermal insulation performance.

2. The Relationship between Down Content and Warmth

Down (complete down clusters) is a key indicator of down quality. The higher the down content, the larger the spaces between the down hairs, the greater the loft, and thus the improved warmth. Generally speaking, a down content of over 80% is sufficient for daily warmth, while a down content of over 90% is considered high-end.

3. Advantages of High-End White Goose Down

White goose down is often used in high-end duvets because of its large, fine, and soft down. With a down content exceeding 90%, it offers excellent loft and resilience, enabling it to retain heat for extended periods in low-temperature environments. White goose down is pure white and easier to maintain its original bright appearance after washing.
4. Other filling options
To meet the needs of different consumer groups, "artificial down" filled with synthetic fibers (such as polyester) has also appeared on the market. Although it is cheaper and easier to wash, its warmth and comfort are still slightly inferior to natural goose or duck down.
Where can I find a duvet cover suitable for my new room?
1. Online e-commerce platform search tips
Large e-commerce platforms such as Tmall, JD.com, and Alibaba (1688) have dedicated home textile channels. Use the keyword "duvet cover" to search, and you can limit the filter conditions to material (suede, suede, pure cotton, etc.), color, size, and whether it can be customized. Reading customer reviews and store sales can help you quickly judge the quality of the product and the level of after-sales service.
2. Offline store shopping tips
Large home furnishing stores (such as IKEA and Red Star Macalline) and professional bedding stores offer on-site touch experience. You can directly experience the softness, thickness, and color of the fabrics on-site; store staff will often provide professional sizing services to help customers choose the perfect duvet cover.

How often should duvet covers and comforters be washed?

1. Duvet Cover Cleaning Frequency and Reasons

It's recommended to wash duvet covers every two weeks, especially during the warmer months between spring and summer, when allergens like dust, pollen, and dander easily accumulate on the cover. If you live in a humid environment or have family members with allergies, you can reduce this frequency to weekly to maintain indoor air quality.

2. Duvet Body Cleaning Frequency and Precautions

Duvet bodies require relatively low cleaning frequency, generally every six months. Frequent washing can cause the natural oils in the down fibers to be lost, affecting their loft and warmth. If noticeable odors, clumping, or localized stains develop, they should be professionally cleaned in advance. 3. Washing Method and Maintenance Tips

Water Temperature: Use warm water between 30–40°C to avoid damaging the natural oils in the down.
Detergent: Choose a neutral, low-foaming detergent specifically formulated for down. Avoid using regular laundry detergents containing bleach or strong alkalinity.
Rinse: Rinse repeatedly until all detergent is completely removed to prevent residue from clumping the down.
Spin: Gently spin dry or use a low spin speed to prevent compaction.
4. Storage and Daily Care Recommendations

Drying: After washing, lay the duvet flat in a cool, well-ventilated area to dry. Avoid direct sunlight, which can cause discoloration or deterioration of the down. Pat the duvet gently when it is 70% dry to restore the down's fluff.
Storage: Use a breathable storage bag or cotton cloth to prevent vacuum compression and clumping of the down. Place moisture-proofing agent inside the bag to keep it dry.
Return the duvet cover and duvet body regularly: Turn the duvet cover over once a month to distribute the load evenly and extend its life.
