Identification Of Underwear Fabrics

Because underwear is close to human skin,

Fabric is made of yarns, and yarns are made of fibers.

Therefore, the fabric characteristics and fabric composition.

Cotton, silk and linen have good moisture absorption and breathability in natural fibers.

However, natural fibers have poor shape retention and poor scalability, so they are powerless for repairing underwear, while chemical fibers show their advantages.

Therefore, in order to enable these two fibers to play their respective advantages, natural fibers and chemical fibers are often blended to meet the requirements of proper blending ratio or to use different fibers in different parts.

For example, the bra cup is made of cotton with good hygroscopicity, while the sideband is made of chemical fiber fabric with good elasticity.

At present, many underwear are designed by double layer design, that is, the natural skin is used on the next layer of skin, and the surface is made of beautiful synthetic lace, which is beautiful and comfortable.

This kind of underwear is thick and suitable for winter.

A simple way to identify fabrics

There are two ways to identify fabrics effectively when choosing underwear: one is the perception method, the other is the sign recognition method. Two.

Perception recognition method:

The method of perception needs some experience, but it is not difficult to do so. As long as we usually try to touch all kinds of fabrics when we go shopping, it will be rewarding over time.

* the fibers can be roughly separated from the following four aspects.

1, handle: very soft is silk, viscose, nylon.

2, weight: nylon is lighter than nylon, acrylic and polypropylene. The weight of the silk is cotton, linen, viscose, and rich fiber. Vinylon, wool, vinegar fiber and polyester are similar to silk weight.

3, strength: stretch to break with hand, the weaker strength is glue, vinegar fiber, wool; stronger is silk, cotton, linen, synthetic fiber, etc.; after wetting, the strength drops obviously is protein fiber, viscose, copper ammonia fiber.

4, extension length: when stretching with the hand, the larger elongation is wool and vinegar fiber; the smaller is cotton and linen; the moderate is silk, viscose, rich fiber and most synthetic fibers.

Identification of silk and rayon by hand feeling

1. Silk feels soft and elastic. When it is kneaded, it has a silk sound and a cool feeling. The artificial silk feels rough and hard, and it is not cold and cold.

2, silk gloss is soft, bright but not dazzling; rayon's luster is similar to metal.

3. Grasp the fabric and release it. The silk is less wrinkled than rayon.

4, water drops on the fabric, rub with hand, artificial silk is broken, silk is firm.

* distinguishing all kinds of fibers through sensory characteristics.

Fiber name - Cotton handle characteristics - thin and soft, small elasticity, easy to wrinkle.

Ma - the handle is rough and hard, and often has defects.

Silk - lustrous, soft and light, with a sounding sound and cool feeling when kneading.

Wool - elastic, glossy, warm and not wrinkled.

Polyester - good elasticity, smooth, strong, hard and cool.

Nylon is not easy to break, elastic, smooth, light in weight, not as soft as silk.

Vinylon is similar to cotton. Its gloss is dark, not as soft as cotton, its resilience is not good and its wrinkling is easy.

Acrylic fiber is good for warmth and strength, lighter than cotton and soft and fluffy.

Viscose fiber is softer than cotton, its surface gloss is stronger than cotton, but its fastness is not good.

Sign recognition method

The limitation of perception method is relatively rough, and its application is not wide enough. It is impossible for synthetic fibers and blended fabrics.

For some reputable shopping malls or underwear brands, the fabric of underwear can be known directly by identifying signs.

These signs can only be hung up only through testing of textile quality testing institutions. They are highly authoritative.

Generally, there are two contents in this sign, one is fiber name, and the other two is fiber content (usually expressed in percentage).

Sometimes you will find that the name of the sign is in English, and it looks very laborious. Here are some common Chinese and English names of fibers.

Cotton Cotton acrylic, Acrylic hemp, Linen spandex Polyurethanes wool, Wool polypropylene fiber Polypropylene wire, Silk polyvinyl chloride Polyvinyl Chloride Chloride viscose Rayon copper ammonia fiber Cuprammonuium (Cuprammonuium) polyester polyester acetate fiber nylon nylon nylon) elastic fiber rayon (polyvinyl chloride) rayon rayon rayon.
