Cotton fabric has good hygroscopicity, high moisture retention, good heat resistance, strong alkali resistance and hygiene ,which is the reason why you are willing to buy cotton bedding and garments.
As for the cotton fabric you are concerned about, will it shrink?The answer is yes. But why does cotton fabric shrink, do you know?
1.100% cotton material
The pure cotton fabric is composed of plant fibers. When the fabric is infiltrated, water molecules will enter the cotton fiber and cause the fiber to expand. When the weft (or warp) direction of the fabric expands and becomes thicker, the fabric will shrink. The longer the time in the water, the larger the shrinkage. Of course, this is only relative, and it will not shrink endlessly.
In the process of textile dyeing and finishing of pure cotton fabrics, the fibers are stretched by a certain external force. After finishing, this stretching will temporarily be in a “stable” state. When soaking in water for washing, the water will gradually weaken the connection between the fibers of the fiber, the friction on the surface of the fiber will be reduced, the temporary “stable” state will be destroyed, and the fiber will return to or approach the original equilibrium state. Generally speaking, in the process of weaving and dyeing and finishing, it needs to be stretched many times, and the shrinkage rate of the fabric with higher tension is larger, and vice versa.
3.Fabric yarn count
As we all know that the yarn weaving of cotton bedding can be roughly divided into 128*68, 130*70,133*72,40 satin/60 satin/80 satin and so on. The same (such as pre-shrinking treatment or steam pre-shrinking, etc., to eliminate the potential of fabric shrinkage in advance, after the pre-shrinking treatment, the fabric will generally not have a larger shrinkage).
4.Shrinkage of cotton fabric
For pure cotton fabric products, the national standard shrinkage rate is: less than or equal to 3% (that is, 95cm of 100cm fabric is normal after washing). After washing, the pure cotton bedding should be stretched when it is about to dry. When the quilt is dry, it is useless to stretch it. If your quilt cover is really much bigger than the quilt, shrinking is useless. The general cotton quilt cover shrinks to 10cm, which is a standard 200*230 quilt cover, and the shrunk size is 190*220cm.
5.Correct washing and maintenance of cotton fabric
Do not use hot water for washing, the water temperature should be controlled below 35 °C, it should not be soaked in detergent for a long time, and it should not be ironed at a temperature higher than 120 °C, and it should not be exposed to the sun or dried. Correct washing and drying should pay attention to the shade, use flat laying or use a garden stick-type drying rack, and washing is best done by hand.
