Underwear close to the skin, known as women's "second skin.". High quality underwear fabric brings gentle care to the skin, while poor quality fabric is a heavy burden and injury, so the selection of fabric is particularly important. The following is to popularize the knowledge of underwear fabric.

 

Underwear fabrics are basically divided into two categories: natural fabrics and synthetic fabrics. Natural fabrics can be divided into plant fiber (cotton, hemp and other natural fibers) fabrics and animal fiber fabrics, and animal fiber fabrics can be divided into hair (wool, rabbit hair, etc.) fabrics and secretions (mulberry silk, tussah silk, etc.). Natural fibers are basically used in the intimate parts of underwear. Due to the limitations of natural fiber, synthetic fiber fabrics (polyester, nylon, spandex) are used in underwear. Here are four common underwear fabrics.

 

 

cotton

 

It can absorb sweat, ventilate, keep warm, easy to dye and print. In recent years, manufacturers like to blend cotton with various fibers. Chemical fiber is added into cotton, which is suitable for adjustable underwear. It is not only breathable, but also has supporting effect. However, cotton is easy to lose color and is easy to be damaged by mold and beetle. When it comes to water, the size of cotton shrinks or becomes larger, and its tensile elasticity is poor and easy to wrinkle. Perspiration also reduces the strength of cotton and turns yellow. Cotton is easy to fatigue deformation, sweat absorption is not easy to volatilize. Due to these objective disadvantages, cotton can not be used in underwear ultrasonic technology, only nylon and spandex can.

 

 

silk

 

Good touch and material, no static electricity, sweat absorption and air permeability. The only drawback is that it's not easy to clean. When washing, you have to scrub or dry clean with your hands very gently. Velvet is elegant and luxurious, with a natural smooth feeling. If you use French lace or Swiss embroidery and velvet for decoration, you can achieve a very gorgeous effect.

 

 

Leica

 

Lycra is a kind of high-quality spandex. It is a registered trademark of high-quality elastic fiber developed by DuPont company in the United States. Lycra's extension can reach 4-7 times, and can completely return to the original, the binding force on people is very small. Lycra can be used with any fabric, but can not be woven into fabric alone. Because Lycra's own characteristics are full of elasticity, comfort and supporting force, it makes the fabric have extraordinary resilience. When used in underwear, it not only makes underwear more elastic and more close to the body, but also has a fine, thin and smooth texture.

 

 

modal

 

Modal is a new era environmental protection product, also known as regenerated cellulose fiber. It has air permeability and hygroscopicity. Its soft, smooth and delicate properties make the fabric smooth as silk. It is very comfortable to wear and can not easily fade after washing for many times. However, it is easy to pilling, poor shape retention and wear resistance, and has strong flammability.

 

 

nylon

 

The scientific name of nylon is polyamide, which is often said to be nylon fiber in life. Nylon is made by drawing nylon into fine fibers and then weaving. According to the different materials of nylon, nylon 6 and nylon 66 are common. Nylon fabric has excellent elasticity and elastic recovery. Its wear resistance ranks first among all kinds of fabrics, which is many times higher than other fiber fabrics of similar products, so it has excellent durability. Moreover, the moisture absorption of nylon fabric is better in synthetic fiber fabric, so the clothing made of nylon is very comfortable to wear.
