Cotton clothing feels good and is one of the common T-shirt fabrics. It is naturally soft, feels plump and thick, and is very suitable for wearing. In daily life, people often think that pure cotton fabrics and 100% cotton fabrics are the same fabric. In fact, they are still different. The main difference lies in the different production processes. There are many ways to identify whether a T-shirt is made of pure cotton. Let’s learn about it with me.
The difference between pure cotton T-shirts and pure cotton T-shirts
1. Cotton T-shirt means that the fabric is made of 100% cotton. Pure cotton T-shirt is a T-shirt made of cotton as the textile raw material and interwoven with warp and weft yarns. It contains more than 75% cotton. Just pure cotton. However, with the development of the clothing industry, people usually regard these two fabrics as having the same meaning, but they have different meanings.
2. Depending on the processing procedures and techniques, there are certain differences in the clothes produced by cotton T-shirts. For example, pure cotton clothes are easy to wrinkle, while some 100% cotton clothes Because the fabrics processed are different, they are not prone to wrinkles.
How to identify whether a T-shirt is pure cotton fabric
1. Look at the feel
Pure cotton fabric feels naturally soft, plump and thick, with a slightly astringent and sinewy feel. The pulling range is small, and the recovery speed after pulling is slow; while the chemical fiber fabric feels soft and slippery, has a large stretching range, and will spring back to its original shape as soon as you let go. Rub the edge threads. After rubbing the pure cotton, a lot of thin threads will come out. You can see fibrous substances of different thicknesses. The structure of the chemical fibers is very uniform, and the change in thickness is not obvious. But be careful, you must choose the thread ends of the fabric on the clothes. The threads used for sewing are often made of cotton and cannot be used as a reference for distinction
In addition Because cotton yarn is tougher and less elastic, it will take a little longer to recover from wrinkles on pure cotton clothes. Let me teach you the most rustic and most effective way to identify them: pick them up and hold them in your hands, and then let go. If wrinkles appear, If it is very powerful, it means it is made of cotton, or contains a lot of cotton. If there are very few wrinkle marks, it means other ingredients are mixed with it.
You can also fold the fabric in half, and then scrape it along the edge with your fingernails. After unfolding, the more obvious the scratches are, the higher the cotton content is, and the pure fiber content is higher. The fabric will not leave scratches.
2. Look at the gloss
Except for those treated with caustic soda Except for mercerized cotton, pure cotton fabrics have no obvious luster, and the color is natural and soft. When the clothes are put down naturally, the drape is natural and there is little “reflection”. When purchasing, you can flatten the clothes and add a certain amount of tension, and then connect the fabric to the body. Point it downward at a 45-degree angle to the light source. If there is a flash of bright light, then this must be a piece of clothing with a high content of chemical fibers. In addition, due to the addition of fluorescent whitening agents, white clothing made of chemical fiber will be whiter than pure cotton clothing, and may even feel dazzling.
3. Look at water absorption
As we all know, pure cotton The water absorbency of fabric is quite good. Dip some water into pure cotton clothes, and then squeeze out the water with your hands. If the water still cannot be squeezed out, it proves that it is not pure cotton. If it is pure cotton, squeeze it out. After the water is applied, wrinkles will appear.
4. Smell the smell
From the seams of clothing Pull out a small piece of yarn and conduct a fire inspection on it. Real natural cotton fiber will not melt and shrink when burned, but will produce a natural yellow flame like paper. At the same time, it will produce the smell of burning paper. After burning, it will produce a flame that can be crushed. There are gray-white ashes; while chemical fibers will melt and drip when burned, and there will be black smoke and glue smell, and the burning will form black hard spots. Of course, this inspection method is unsafe and unrealistic for ordinary consumers, so we can only use the first few methods to judge.
