How to judge the quality of silk and how to identify the authenticity of silk

The quality of silk is judged from the following aspects:

1. Observe the luster. The luster of real silk is soft and even, bright but not harsh. Although the luster of rayon fabric is also bright, it is not soft and pleasing to the eye.

Although the luster of polyester yarn is uniform, there is glitter or bright silk. Nylon silk fabrics have a poor luster, as if coated with a layer of wax.

2. Hand touch feeling. When you touch silk fabrics, you have a feeling of pulling hands, while other chemical fiber products do not have this feeling. The rayon fabric is smooth and soft, but not crisp. Cotton silk weaving hands are hard but not soft to the touch.

3. Examine the creases. When the hand pinches the silk fabric tightly and then releases, it has no creases because of its good elasticity. Rayon fabrics have obvious creases after being released, and the creases are difficult to restore to their original shape. Although nylon silk has creases, it can also slowly return to its original shape, so don't be fooled by its illusion.

4. Test the fiber tensile force. Extract a few fibers at the edge of the fabric, moisten it with your tongue, if it is easy to break in the wet, it means that it is rayon, if it is not pulled off in the wet, it is silk, if the fiber is very strong in the dry and wet state, it is nylon silk or polyester yarn that is not easy to break.

5. Listen to the sound of rubbing. Because the silk is protected by sericin and resistant to friction, dry silk fabrics will make a sound when rubbing against each other, commonly known as: "silk sound" or "silk sound"; Other chemical fiber products appear silently.

By feel, good hands are slippery to the touch, and there are no wrinkles.

There are several ways to identify the authenticity of silk:

1. Observe the luster. The luster of the silk fabric is soft and even, although it is bright but not dazzling. The luster of rayon fabrics is also bright, but not soft. Although the luster of polyester yarn is uniform, there is glitter or bright silk. Nylon silk fabrics have a poor luster, as if coated with a layer of wax.

2. Hand touch feeling. When touching silk fabrics, there is a feeling of pulling hands, while other chemical fiber products do not have this feeling. The rayon fabric is smooth and soft, but not crisp. Cotton silk fabrics do not feel soft.

3. Examine the creases. When the silk fabric is pinched tightly by hand and then released, there is no crease because of its good elasticity. Rayon fabrics have obvious creases after hand-kneading, and the creases are difficult to restore to their original shape.

Although there are creases in nylon silk weaving, they can also slowly return to their original state, so don't be confused by their false appearance.

Before buying silk. Rub the silk with your hands. If you feel warm when rubbing, buy it!

It's real. With artificial or synthetic silk, it is impossible to experience warmth when rubbing. One more thing, when rubbed with real silk it sounds like walking on fresh snow.

If you don't know how this sounds, go for it!

You can also use your wedding ring! Real silk can be easily threaded through a wedding ring because silk is naturally pliable and smooth. Rayon, on the other hand, creaks and doesn't pass easily.

Consider**. Of course, real silk is ten times more expensive than synthetic silk. While sometimes synthetic filaments are also very high, most of them are low and a good indication of their poor quality.

Check the gloss of the material. Silk is known for its luster. The gloss is usually due to the combination of threads, which gives the material a special shine.

The color on the surface seems to change with the angle of the light. However, no matter which angle the light falls on, rayon will only produce a white sheen.

Hand-woven silk has a uniqueness. There are slight variations in the uniformity of the texture, which is very noticeable. But don't worry!

These are natural and expected. These defects are what make the product unique. Woven silk looks perfect.

They are flawless in texture and instead lose their personality! The synthetic fibers also look perfect, but sometimes they are deliberately slightly blemishesed, but unnatural, so that they can pass through as silk.

Burning, this is probably the best and most authoritative test for finding silk. You can take a few threads out of the material and burn them with a flame. Silk burns, smells of burnt hair.

When you burn the edges of the silk fabric, the flame is invisible and stops burning once the flame is removed. The resulting ash is black, and when twisted with a finger, it turns into powder. Rayon, it's the opposite.

When synthetic filaments are burned, there will be a smell of flame and plastic. No ashes were produced. Needless to say, you may want to use this step with caution as it can start a fire if you are not careful.

If you really need to know, consider taking a chemical test. If you have the necessary chemicals in your backup lab, 16 grams of copper sulfate, 8 grams of glycerin, 1 tablespoon of caustic soda, 150 ml of water, immerse a small piece of silk in the solution. Silk dissolves in a few minutes, whereas rayon does not.

In fact, it is very simple to distinguish between real and fake silk, that is, to look at the color, second burning, smell the taste, and use three uses 84, which can basically be determined as real silk.

As for the filament and short filament, the distinction is also very simple, pull up the filament by hand, and look at the filament evenly to see that the filament is very long, indicating that the quality is not bad, the short filament is generally a lot of knots in the middle, and see a lot of breaks.

Squeezing silk can also pass the above identification, now many unscrupulous businesses wrap squeezed silk in mulberry silk**, squeezing silk to be thicker, the quilt made is not as soft as mulberry silk, and to be fluffy, in fact, the difference is still obvious.
