What is the quick and convenient way to analyze the basic composition of textile fabrics? 5

The easiest way to use this is the combustion method.

Fiber name: Burning state, odor, ash.

Cotton burns quickly, producing a yellow flame and blue smoke, and the flame can continue to burn, sometimes extinguishing the burning paper smell of white powder.

Hemp burns quickly, producing a yellow flame and a blue smoke that smells of burnt withered grass and an off-white powder.

Silk burns slowly, first curls up and then smokes, and the flame is extinguished Burn hair smell gray-brown balls, fragile.

The hair is first curled up and then smoked, burning while smoking, the flame is yellow, the smell of singe, black hard lumps, fragile.

Viscose burns quickly, yellow flame burns paper smell ash white very small pieces.

Polyester is smoking, burning while melting and shrinking, yellow flame is unpleasant, and it is a black and brown hard lump that can be broken.

Nylon burns slowly while melting, curling, and shrinking; Orange flame, blue flame edge, celery scent, light brown lumps, not broken.

Acrylic Burning slowly while melting, flame white with slight flash and slight black smoke Fishy smell Black hard balls, brittle.

Acetic acid melts and burns slowly, yellow flame Acetic acid smell Black hard lump that can be broken.

Hope it helps.

The combustion method is the most basic and fastest method. Pull out one of the yarns inside, burn it and smell it.

There are several physical ways to distinguish the ingredients. 1. Feel distracted. 2. Warp and weft yarns of burning fabric. There are some specific methods on these websites that you can refer to.

1. Softness. It refers to the soft bending, lightweight, fluffy, smooth and waxy feeling, and the stiffness, flatness and smoothness are weak. To make the fabric soft, can improve the fluffiness of the yarn, choose a finer yarn, and the weaving density should not be too high.

2. Compliance. The ability to follow the soft deformation of the curved surface of the body. 3. Stiffness.

When you touch the fabric, you can feel the stiffness, the reaction force of the opponent, and the feeling of elasticity and fullness. For example, the feel of high-density fabrics made of elastic fibers and yarns. To make the fabric have a stiff feeling, the manufacturer of hygroscopic and quick-drying mesh fabric suggests that coarser fibers should be selected, the fiber modulus should be increased, and the yarn tightness and weaving density should be improved.

4. Smoothness. The feel of coarse hard fiber or strong twisted yarn is mainly the surface feel of the fabric, and the overall rigidity of the fabric has an enhanced effect. A slip feel can be achieved by twisting and using fibers with grooves or uneven surfaces.

Different textile fabrics are not the same color, hardness is not the same, skin feel is different, there are cotton textile fabrics, there are silk textile fabrics, there are many types.

The textile fabric is very soft, especially easy to clean, very breathable to wear, very fluffy, especially textured, looks very straight, and is very soft to the touch.

The specific characteristics are that the feel is better, the feel is softer, and it is very strong and cool, which can make us more temperamental, and it is particularly warm and very light.

Commonly used fabrics include the following:

1. Cotton cloth is a very common fabric, which is durable and easy to process. It can be reused into a variety of different products, such as clothes, bed sheets, towels, etc.

2. Linen cloth is another cloth that is often used. It is tougher and more durable than cotton, and it is breathable. Linen cloth can be used to make shopping bags, curtains, and decorative items.

3. Wool is a natural material with good warmth and elasticity. It can be reused into products such as blankets, carpets, stools, and wool sweaters.

4. Silk is a soft and smooth material that is usually used to customize high-end clothes and home decoration. Old silk can be reused into products such as throw pillows, curtains, and clothes.
