It is recommended to replace the down-proof fabric. If you use this fabric, most of the down will leak sooner or later. The best way is to stop it from running, find a place where you can make duvets again, and then choose a down-proof fabric and replace it. This is only the money for replacing a quilt fabric, at least it is more cost-effective than buying a new duvet.

If you don't want to disassemble the duvet, you can directly add a layer of down-proof fabric outside. The disadvantage is that the duvet will be thicker and there will be an extra layer of material inside.

Causes of hair leakage in duvets

1, the first reason is that the fabric density is not enough, which leads to poor cashmere prevention effect.

2. The second reason is that a large number of inferior fillers such as feather silk, flying silk and wool chips are mixed in the down, so that no matter how dense the down-proof fabric becomes, there may be wool leakage.

The third reason is that the eye of the needle is too thick, and the flying silk and wool are all drilled out from the eye of the needle.

How to make the cloth watertight

1, it is a common practice in the industry to do cashmere-proof post-treatment on fabrics to achieve cashmere-proof effect.

2, it is to make a layer of anti-cashmere liner, and the outer fabric does not need anti-cashmere, which is generally used for high-grade silk-cotton interwoven jacquard fabrics.

How to choose cashmere-proof fabric

1, to buy a duvet, you should first choose the down-proof material, and then pay attention to the air permeability, softness and noise when you cover it.

2. When buying a duvet, look at the duvet content written on the trademark. If the cashmere content is high, but the outer fabric is relatively low-end, then you need to pay attention to this. Since the cashmere content is relatively high, why not use good fabrics? This kind is not recommended.

3. If the down is marked with low down content, but its fabric is thin and the gap of the fabric is large, it is not recommended to buy it, so it is easy to leak hair.
