Tissue shrinkage is pure physics against which humanity is powerless. Rather, we are able to influence it, but then the fabric ceases to be 100% natural. Therefore, we can only reconcile. After all, at the moment we are not ready to completely give up pure cotton, wool, silk or flax. We appreciate these fabrics for their naturalness and naturalness. For tenderness, touch to the body, etc.
In the text below, we will try to understand why shrinkage occurs and what can be done about it.
Only natural fabrics always sit down: linen, cotton, wool, silk, viscose. If artificial fibers are added to natural fibers, the effect is reduced. Note that it does not disappear at all, but only decreases! It is important. Fabrics that contain only synthetic threads do not sag at all.
So why does the fabric decrease in size at all?
The whole thing is in the process of making fabric. During production, the warp thread is strongly stretched. When immersed in water, the fiber absorbs moisture, swells, releases tension and tries to return to its original state. This explains the fact that the fabric at the base sits stronger than the width.
We often hear questions from customers: "If I wash the fabric at the specified temperature and everything is great, it will not sit down?"
Unfortunately, this is not the case. Of course, do not exceed the specified temperature. But today has added a new factor to this phenomenon. Fabric shrinkage also occurs during spinning in modern washing machines. Even if you set the delicate mode, 600 rpm and temperature difference still do the trick.
What to do to avoid halepa and after washing the thing remained in the size you need?
The answer to this question was invented a long time ago. When buying natural fabric, take into account the shrinkage factor. It will depend on the composition of the fabric. Thus, cotton can give 2-5% shrinkage, depending on the type of fabric, but flax and wool - up to 6%. Natural silk is less susceptible to deformation, while artificial silk can lose up to 7% in length. Fabrics of mixed composition will shrink depending on how much natural fiber they contain. Knowing about this feature of fabric it is necessary to consider this moment before you will cut a cloth. And before you cut the fabric, it must be decatized.
How exactly to know the shrinkage factor?
A manufacturer who respects himself and his customers always indicates the shrinkage factor in the product information. That's why you can check all the information with your fabric seller. And there are even special calculators on the Internet that will allow you to easily calculate how much fabric you need to take for your project.
What is decating?
Decatation is the saturation of the fibers of a fabric with moisture in order for them to swell. Depending on the type of fabric, it can be hot steam, warm water, hot water and so on. After the fabric is completely dry, there is a natural shrinkage of the fabric. Each type of fabric has its own scheme of forced shrinkage.
Actually everything. While we grind for natural fabrics, we should only take into account this feature of them. Seek advice. Let's help to pick up.
