What to Look for When Buying Sheets?
It is important to consider the flannel type of sheet you are looking for. Normally, they are of two main categories – the cotton sheets and micro sheets.
The major difference between them is that cotton flannel is made of cotton while micro flannel is made of polyester. Generally, when it comes to insulation, polyester is slightly better at insulating heat than cotton. Cotton is better than polyester at retaining heat.
Most sheets are treated with chemicals (including chlorine, formaldehyde, and silicon) to keep them from shrinking, losing their shape, and wrinkling. Some are treated with alkalis to produce a sheen.
A handful of manufacturers offer pure-finish sheets, meaning that no chemicals were used or that all traces of chemicals used during manufacturing have been removed. You’ll have a harder time keeping these sheets wrinkle-free, but it may be worth it if you suffer from allergies or chemical sensitivities
You may not think much about it, but the country of origin plays an important role. As far as the market is concerned, films from Germany or Portugal are among the best. When it comes to micro flannel, China seems to be the best, especially in terms of the weight of the fabrics. In other words, beware of counterfeits coming from this part of the world.
It is important to stay away from cotton-polyester blends or other blends. These blends promise to increase the level of warmth and comfort, they also contain many fiber bundles that are very difficult to pull away from the base fabric.
Another thing to remember is to stay away from sheets that contain hazardous chemicals like flame retardants. The reason we say this is because this type of sheets is often laden with dangerous chemicals, which may affect the quality of your sleep in the long run. The smell they give out is sure to cause you a certain degree of discomfort in the first few days after unpacking.
It is important to keep in mind when using flannel sheets that they are often blurry after being washed several times. If they are new, these sheets are packed in mils for easy transportation that pushes the fibers down. After a few washes, fibers retain their intended fluffiness as the surface loosens. Note that they lose lint over time, mainly because the fibers are pulled away from the base fabric. Interestingly, most linting occurs during the first wash cycle.
