How to distinguish between natural fibers and non-natural fibers?

As we all know, fiber types can be divided into two main categories: natural fibers and non-natural fibers. Today, letZhejiang Dingyi New Materials Technology Co., Ltd.introduce what kinds of fibers are there and how to identify them.

Natural Fibers

Natural fibers are divided into vegetable and animal fibers. Nowadays, many big luxury brands choose all-natural materials for their fabrics, these materials are good, but they also have a life span. Whether silk, cotton, or linen, will lose its original luster with each wash, they can not always maintain a good condition. Silk is a very common material in animal fibers, while cotton and linen are common materials in vegetable fibers.

How to identify animal fibers?

You can generally burn it with a lighter, which is a simple and crude method, but can quickly help you confirm whether the ingredients are real or not. The burned part will have a little hard lump but do not touch it immediately after burning, because if the fabric is not pure containing chemical fiber components, this behavior may scald you. Although this method can’t identify the proportion of ingredients, if the pinch is powder without any hard lumps, then it means that the purity of the fabric is very high.

In addition, animal fibers contain a lot of protein. You can smell the scent when you burn them. There will be the smell of burnt feathers, just like the smell you burn a piece of hair.

How to identify vegetable fibers?

As with animal fibers, the combustion test can also be used. Cotton or linen are peculiar when burned because their raw materials are grown in the earth, so the feeling of burning vegetable fibers is the same as burning vegetation. It will keep on burning if you don't blow it out. After burning, the ash will be very delicate and almost completely grain-free, the burning speed is also very fast, and the smell is also like the smell of plant ash, it's very easy to identify.

Non-naturalFabrics

The above is the introduction of some common natural fabrics. Next, let's learn about non-natural fabrics. Non-natural fibers include man-made chemical fibers (spandex, nylon, polyester, etc.), and cellulose fibers. Among chemical fibers, spandex has a common large category of varieties - Lycra, among chemical fibers, spandex has a common large category of varieties - Lycra, which is more or less contained in the jeans we wear. Nylon fabric is often used to make mountaineering wear, or winter wear, because it has good abrasion resistance, good moisture absorption, and is a light fabric. Polyester is another very common chemical fiber, you may not have worn clothes made of silk or wool, but you must have worn clothes made of polyester. Cellulose fiber includes rayon, copper spandex, modal, and bamboo fiber. It is a material extracted from plants, so it has all the advantages of natural fibers and is relatively well taken care of.

How to identify chemical fibers?

If it is a chemical fiber, there will be black smoke rolling when it burns. In addition, after burning there will be a large hard block, and very scalding, so if the burning fabric has a cloud of heavy black smoke, we should pay attention to never touching it with our hands.
