Why did I buy a quilt with a width of 1.6 meters and wash it to 1.5 meters? Is it pure cotton?

Because the sheets are pure cotton, they will shrink after washing.

It is normal for sheets to shrink. If they don't shrink, the sheets are not pure cotton.

Pure cotton fabric is a kind of textile with cotton as raw material and warp and weft interwoven by loom. There are many kinds of pure cotton fabrics with different colors. According to the dyeing method, it can be divided into primary color cotton cloth, dyed cotton cloth, printed cotton cloth and yarn-dyed cotton cloth, and according to the fabric structure, it can also be divided into plain cloth, twill cloth and forged cloth. 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 cloth increases and the surrounding temperature is higher, all the water contained in the fiber will evaporate and disperse, so that the fabric can keep water balance and make people feel comfortable. Because cotton fiber is a poor conductor of heat and electricity, its thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a lot of air can be accumulated between fibers, and air is also a poor conductor of heat and electricity, so cotton fiber textiles have good moisture retention, and wearing pure cotton clothing makes people feel warm.
