What is the difference in thermal insulation performance between polyester fiber quilt cover sets and pure cotton quilt cover sets?

Polyester fiber, as a synthetic fiber, has remarkable performance in the field of warmth retention due to its unique fiber structure and physical properties; while pure cotton, as a traditional natural fiber, also has unique performance in warmth retention, breathability and comfort. Advantage.

The thermal insulation performance of polyester fiber quilt covers comes from its tight fiber molecular structure. The tight fiber molecular structure of polyester means the gaps between fibers are relatively small. This tight arrangement effectively blocks the penetration of cold air, thereby forming a warm barrier inside the quilt cover. Even on cold nights, the low temperature outside will hardly affect the warm environment inside the quilt, allowing people to enjoy a comfortable and pleasant sleep. The tight structure of polyester also helps trap air. Air is a poor conductor of heat, so the more air stored inside a duvet cover, the better the insulation. The tight structure of polyester fiber allows it to capture more air and tightly wrap this air inside the quilt cover, forming a warm air layer. This air layer can effectively block heat loss and keep the quilt warm. Polyester also has good elasticity and durability. This means that the thermal properties of the polyester duvet cover remain unchanged even after prolonged use and cleaning. It is not easy to deform or pill, and can maintain its original shape and warmth retention effect for a long time. Although polyester duvet covers are excellent at providing warmth, there are some potential drawbacks. For example, polyester is relatively poorly breathable due to its tight fiber structure. During sleep, the human body will continuously emit heat and moisture. If the breathability is poor, the inside of the quilt may become damp, thus affecting the quality of sleep. In addition, polyester fiber has relatively poor hygroscopicity and is not as effective in absorbing and discharging moisture as natural fibers such as pure cotton.

Polyester’s thermal properties don’t come without a price. Its tight fiber structure also results in reduced breathability. During sleep, the human body continuously emits heat and moisture, and poor breathability may cause the inside of the quilt to become damp, thus affecting the quality of sleep. In addition, polyester fiber has poor hygroscopicity and is not conducive to keeping the quilt dry.

In contrast, pure cotton quilt covers show different characteristics in terms of warmth retention performance. Pure cotton quilt cover can effectively store air due to its porosity and elasticity of natural cotton fiber. Air is a poor conductor of heat and electricity, so a pure cotton quilt cover can effectively prevent heat loss and keep the quilt warm. At the same time, pure cotton fiber is also very hygroscopic and can absorb moisture emitted by the human body to keep the quilt dry.

In terms of breathability, pure cotton quilt covers are significantly better than polyester fiber quilt covers. The porous structure of pure cotton fiber allows air and moisture to pass freely, thus keeping the quilt dry and comfortable. During sleep, the human body needs to breathe continuously, and the breathability of pure cotton quilt covers can better meet this need and make people feel more comfortable.

Pure cotton duvet covers also excel in comfort. Its good skin-friendliness and comfortable and soft feel make the pure cotton quilt cover bring a warm and comfortable touch when used against the skin. Although polyester fiber quilt covers have good thermal insulation properties, they are relatively hard and slippery and may cause discomfort when used.

Polyester fiber quilt cover combinations and pure cotton quilt cover combinations each have their own advantages and disadvantages in terms of warmth retention performance. Polyester fiber duvet covers, with their tight fiber structure and excellent windproof properties, can effectively keep the quilt warm in cold weather; however, poor breathability and moisture absorption may affect sleep quality. The pure cotton quilt cover, with its porous, hygroscopic and breathable characteristics, can keep the quilt dry and comfortable while maintaining warmth. Therefore, when choosing a quilt cover, consumers need to weigh various factors based on their own needs and preferences, and choose the quilt cover material and combination that best suits them.
