All cotton has good moisture absorption, high moisture retention, good heat resistance, strong alkali resistance, and hygiene, which are the reasons why you are willing to choose all cotton bedding. As for your concern, will cotton shrink? The answer is yes. But why does cotton shrink? Do you know? Let me tell you.

The quilt cover of pure cotton is composed of plant fibers. When the fabric is soaked, water molecules will enter the interior of the cotton fibers, causing them to swell. When the warp (or weft) expansion of the fabric becomes thicker, the fabric will shrink. Therefore, the longer it is immersed in water, the greater the shrinkage. Of course, this is only relative and will not continue to shrink endlessly.

During the textile dyeing and finishing process, pure cotton fabrics are subjected to certain external forces for stretching. After finishing, this stretching will temporarily remain in a "stable" state. During immersion washing, water gradually weakens the connections between fiber molecules, reduces the friction force on the fiber surface, and disrupts the temporary "stable" state, causing the fiber to return to or approach its original equilibrium state. Generally speaking, during the weaving and dyeing process, it is necessary to stretch multiple times, and fabrics with higher tension will have a higher shrinkage rate, while those with lower tension will have a lower shrinkage rate.

Everyone should know that the yarn weaving of all cotton bedding can be roughly divided into 1288 * 68, 130 * 70/13372/40 satin/60 satin/80 satin, and so on. The higher the yarn weaving, the more high-end the fabric will be, and the treatment of the fabric will also be different (such as pre shrinkage treatment or steam pre shrinkage, etc., to eliminate the potential for fabric shrinkage in advance, and after pre shrinkage treatment, the fabric generally will not shrink significantly).

The commonly used cotton bedding can be roughly divided into four types: ordinary cotton four piece set, combed cotton four piece set, mercerized cotton four piece set, and ground wool four piece set. The ordinary shrinkage rate can only be determined by personal luck. Generally speaking, good manufacturers can still rest assured of their products. Combed cotton and mercerized cotton are usually processed before leaving the factory, and there is no problem. Regarding ground wool, I can only say that the cheaper the shrinkage rate, the greater the price. Why is the same thing cheaper? Insufficient size, reduced post-processing steps.

For pure cotton fabric products, the national standard shrinkage rate is: less than or equal to 5% (that is, 95cm after washing a 100cm fabric is normal). Pure cotton bedding should be stretched when it is about to dry after washing. When the bedding dries, it will be useless to stretch it. If your quilt cover is really much larger than the quilt heart, shrinking is useless. A typical pure brocade quilt cover shrinks by 10cm, which is a standard 200 * 230 quilt cover. After shrinking, the size is 190 * 220cm.
