How many Jin of quilts should I cover in winter?

8 kg cotton quilt is suitable in winter.

Introduction to the quilt [mián bèi] Compared with down, silk, wool and other quilts, the quilt has the advantages of good warmth and softness. The quilt has no static electricity and is suitable for patients with cardiovascular diseases.

The quilt made of 100% cotton has four typical characteristics:

(1) hygroscopicity: cotton fiber has good hygroscopicity. Under normal circumstances, fiber can absorb water into the surrounding atmosphere, and its water content is 8- 10%, so it contacts human skin, making people feel soft but not stiff. If the humidity of cotton increases and the surrounding temperature is high, all the water contained in the fiber will evaporate and disperse, so that the quilt can keep the water balance and make people feel comfortable.

(2) Moisture retention: Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between fibers, and air is a poor conductor of heat and electricity, so the cotton quilt has good moisture retention, which makes people fully feel warm and comfortable when using.

③ Heat resistance: The quilt has good heat resistance. When the temperature is below 1 10℃, it will only cause the water on the quilt to evaporate and will not damage the fiber. Therefore, the use of pure cotton at room temperature has no effect on its quality, thus improving the environmental applicability of pure cotton quilts.

(4) Hygiene: Cotton fiber is a natural fiber, the main component is cellulose, and there are a few waxy substances, nitrogen-containing substances and pectin. The quilt has been tested and practiced in many aspects, and the contact between the quilt and the skin has no stimulation or negative effect. Long-term use is beneficial and harmless to human body, and has good sanitary performance.
