The new bedding has shrunk in the wash! Is it a quality problem? In fact, pure cotton, silk, tencel, linen and other natural fibers, more or less have shrinkage problems. So why do natural fibers shrink?
Shrinkage cause
1In the production and processing process, the fiber should be constantly stretched, and even over-stretched, the fabric will have a potential shrinkage rate, so the newly bought bedding will restore the original length after the water, and the shrinkage will result.
2After the fiber is fully absorbed in water, it will swell, increase in diameter, but shorten in length. Therefore, the shrinkage rate of fabric is related to the hygroscopicity of fiber, and the greater the hygroscopicity, the greater the shrinkage rate; On the contrary, the shrinkage rate is smaller.
Shrinkage rate standard
Shrinkage rate refers to the percentage of fabric shrinkage after washing or soaking. The shrinkage rate of synthetic fiber and mixed textiles is the smallest, followed by wool, linen, cotton, silk shrinkage is larger, and the largest is viscose fiber, rayon cotton, artificial wool fabrics.
1Different fabrics, shrinkage rate is different.
Generally speaking, the fiber with large hygroscopic property expands after soaking in water, the diameter increases, the length decreases, and the shrinkage rate is large. If some viscose fiber water absorption is as high as13%While synthetic fiber fabric has poor hygroscopic property, its shrinkage rate is small.
2The density is different, and the shrinkage rate is also different.
If the warp and latitude densities are similar, the warp and latitude shrinkage rates are also similar. Fabric with high warp density will have a large warp shrinkage, and conversely, fabric with greater weft density than warp density will have a large weft shrinkage.
3The shrinkage rate is also different with different yarn thickness.
The shrinkage rate of the cloth with thick yarn is large, and the shrinkage rate of the fabric with fine yarn is small.
4The production process is different, and the shrinkage rate is different.
In general, the fabric in the weaving and dyeing process, the fiber should be stretched many times, the processing time is long, the shrinkage of the fabric with larger tension is large, and the reverse is small.
5Improper washing care, shrinkage rate is different.
Different washing time, temperature, detergent, drying method, etc., will affect the shrinkage rate of the fabric.
How to prevent the bed from shrinking
1When choosing bedding, in addition to choosing a brand with good quality and high reputation, we should also pay attention to the fiber characteristics of the fabric, understand the shrinkage rate of the fabric, and choose the appropriate size.
2When washing the bed, you should follow the instructions on the washing label, choose the appropriate washing method and temperature, and avoid long-term immersion and high temperature washing.
3When drying bedding, try to avoid using high temperature drying, choose natural drying or low temperature drying to reduce shrinkage.
4For the bed that has shrunk, you can try to gently stretch it after soaking in warm water, and then lay it out to dry, and sometimes you can recover some of the length.
In short, the shrinkage of bedding fabric is a common phenomenon, understand its causes and shrinkage rate standards, take the correct washing and care methods, can effectively reduce the shrinkage problem, extend the service life of bedding.
