Comprehensive identification techniques for commonly used apparel fabrics

I. Identification of the rayon cloth to buy artificial cotton cloth, also known as cotton silk. Because of its outstanding characteristics of drape, flowing, bright colors, and low price, it has become an ideal skirt material for popularization. So, how to buy artificial cotton cloth?

1 Look at the organization. Rayon cloth is mostly plain weave. Due to the poor strength of viscose fibers and non-abrasiveness, we should choose a tight fabric to increase the service life of the fabric.

2 increase the size. Artificial cotton silk is a pure dry fiber fabric, the shrinkage rate is generally 8% to 10%. therefore. Before buying, you must take into account the shrinkage rate and make more headway.

3 Scope of application. The rayon has poor elasticity, poor wear resistance, and poor wrinkle resistance. It is not suitable for high-end clothing such as suits, but is suitable for all kinds of casual clothes, pajamas, skirts, dresses, quilts, curtains, etc., so consumers should put the performance characteristics of artificial cotton silk. Use it together with its use.

4 Observe the defects. The rayon fabrics generally have fewer weaving spots, and in particular, the yam fabrics are much smaller than the cotton fabrics. Because the rayon cloth is plain, the weft should be perpendicular to the hem. Be careful not to appear weft. For printing cotton silk. The main focus is to observe whether the fabric has any defects. Such as color, color is not allowed, color is not correct and so on.

In the use of artificial cotton silk should pay attention: the first water, after cutting, cutting size should also be slightly larger; avoid soaking in water for a long time and wash vigorously with soap; viscose fiber light resistance is poor, avoid drying after washing; sewing clothes At the time, the seams should be loosened to avoid yarn breakage and cracks. As long as it is used scientifically, artificial cotton can reach its best wearing effect.

2. Identification skills to buy hemp textiles The hemp fabrics mainly include ramie cloth and linen. Hemp fabrics have strong wear resistance, fast heat transfer, and fast heat dissipation. They are the ideal materials for summer wear and are comfortable to wear and cool. However, poor dyeing. Therefore, the color is single.

The identification of pure hemp fabric: pure hemp fabric, the appearance of meticulous light, fabric texture lines clearly visible. Yarn is thicker than cotton, wool and yarn chemical fiber fabrics. The surface of the fabric is evenly covered with roving and slub yarns. These are the special styles of linen fabrics.

Generally speaking. Pure hemp fabric feels rough and soft, fabrics shake in the hands, there is a very cool feeling. However, the fabric was tightly held by hand and then released. The fabric had more creases and creases of different sizes were distributed. Some of the pure linen fabric surface has some natural small flaws, which is called "hemp material". It is made of natural hemp. If the yarn is viewed from the edge of the fabric, it can also be distinguished from other fibers by its fineness (roughness) and evenness.

Hemp fabrics are distinguished by their relative flatness, uniformity of latitude and longitude, and the number of defects.

The most convenient way to identify linen fabrics is to burn them tenderly. Take a bunch of hemp yarn and ignite it with a match. If it burns quickly, a yellow flame and blue smoke will emerge, emitting a smell similar to that of dry grass or burning paper. The ash will be grey or gray, and it can be identified as a linen fabric.

The identification of true and false hemp fabrics: The real hemp fabric is made of natural hemp fiber, and the fake hemp fabric is made of synthetic fabric or synthetic fabric made of synthetic fibers or synthetic fibers. Due to different raw materials. The difference in taking performance is greater. From a superficial point of view, the real linen fabric is only slightly different from the false hemp fabric on the yarn. The ability to absorb color from the color is weak and the color tends to be light. Imitation hemp fabrics or blended fabrics are stiff and have good wrinkle resistance. Tighten and release the fabric by hand, with little or no wrinkles. When the fabric was identified by the combustion method, the imitation hemp fabric did not ignite the tender grassiness of the pure hemp fabric. If you go to the store to purchase, you may wish to look at the product label before you buy it. The above number is preceded by "" and the words are made of pure hemp fabric. "TR' is a blend of polyester and linen. "RT" is a linen blended product. .

Attention on fabric defects: When purchasing, we must pay attention to weaving defects, dye defects, etc., when checking the flaws of hemp fabrics. The method is the same as other fabrics. However, special attention should be paid to skipping silk, broken wires, broken holes and other defects, because the fabric is plain weave and fine yarn, thin lines, so the above defects affect the appearance of the fabric.

In addition, when purchasing linen fabrics, consumers should also consider the combination of fabrics and seasons and clothing styles, and should play some head in size to prevent shrinkage, the shrinkage rate of linen fabric is generally 6% to 8%

3. Identify the skills to buy silk fabric silk fabric appearance drift, feel light, strong moisture absorption, good air permeability, comfortable wear, is the world's most popular popular fabric in recent years. How can I choose the ideal silk fabric?

At present, there are many kinds of chemical fiber silk fabrics on the market and there are many names. It is difficult to judge whether it is silk fabric or chemical fiber product only by name, especially if the product has no label. To this end, consumers are introduced to identify several real silk and imitation silk.

1 The identification of silk and rayon fabrics. Silk fabrics are soft and shiny, natural silk is not dazzling; rayon is shiny and bright. Especially light rayon, shiny glare.

Silk fabrics feel soft and delicate. Pure silk fabric rubs each other and can emit special sounds, commonly known as "silk" or "sounding." This is one of the ways to identify silk and imitation silk. The rayon feels a little rough and has a cold and cool feeling.

Silk fabrics are laid tightly by hand and released, with little or no wrinkles; while rayon fabrics have more wrinkles, and most of them are wrinkles. The elasticity of textiles is poor, and there are still wrinkles after loosening with a flat hand.

Pull out the cloth and rub it with the tongue tip. The rayon is straight and easy to break, and the dry and wet elasticity is not the same; the silk product has the same dry and wet elasticity.

A small piece of fabric is chewed in the mouth. The silk fabric is chewed into balls for a long time; the rayon is broken into short fibers.

2 Identification of silk fabrics and polyester fabrics. Silk fabric feels soft and polyester fabrics reflect light. Silk fabric feels soft and comfortable. After releasing the fabric, the silk fabric is soft and slow; the fabric of the fabric is stiff and rebounds quickly. Silk fabrics are not as good as polyester fabrics in crease resistance. Not as good as polyester fabrics.

Pull out the fabric management line. Silk stretches easily by hand; polyester filaments are strong and hard to break. This is one of the reliable methods for identifying silk and polyester fabrics.

3 real partner and chemical fiber blended fabric identification. When purchasing such fabrics. To see the label of the product, ask about the blend ratio. A fabric with a high proportion of silk is comfortable to wear. The price is slightly more expensive. Such as silk / dry mixed textiles, viscose mixed sites are usually 25% to 40%, then the price is low, breathable and comfortable. However, viscous fibers have poor resistance. When you release your hand after taking a firm look on the fabric, and there are many wrinkles, there will be more dry plastic fibers (rayon), and vice versa.

Polyester/silk blends are also a mixed textile in the market. The amount of polyester used is 50% to 80%, and 65% polyester and 35% twisted silk sticks are used in China. This fabric has good softness and drape, and it is also strong and wear-resistant, and polyester provides wrinkle recovery and pleat retention. It changes the feel and appearance of pure silk and pure polyester fabrics, and has two fiber characteristics, but polyester Slightly more fabric properties.

4 The identification of silk and nylon yarn. Nylon silk is not the same as silk in gloss. Nylon silk fabrics have poor luster and a waxy feel on the surface. The feel is not as soft as silk, but it is stiff.

When the fabric is released by hand, the nylon fabric is creased, but its crease is not as pronounced as rayon, but it can be slowly restored to its original shape. The silk fabric is basically crease-free.

Tested by spinning, nylon yarn is too easy to be broken; the silk is easy to break, and the strength is far less than nylon yarn.

In summary, the identification method can be simply summarized as follows:

Eyesight. Look whether the fabric luster is soft and bright, whether the color is clear and symmetrical, whether there is color, color, color flowers. The surface has no tangled filaments, and there are no morbidities such as broken meridians and lack of latitude.

Hand touch. Whether the hand feels soft and smooth, and whether it touches the hand when touching the silk surface. If there is no such feeling, it is not real silk.

friction. Relatively dry silk, when rubbed with each other, emits a crisp sound, commonly known as silk scent. If there is no silking phenomenon, it is the chemical fiber silk rather than the real silk.

combustion. A bunch of silk yarn was pulled from the broken side of the fabric and tendered with a match. True silk burns slowly, first curling up into a ball, giving off a scent similar to burning hair. After burning into a dark brown ball, the hands are broken into powder. After the tow leaves the flame, it stops burning.

In addition, there are many considerations for the wearer himself when purchasing silk clothing. According to the wearer's age, personality, hobby, body shape to determine their favorite color and pattern of fabric.

The shrinkage of silk fabrics is generally relatively large. When purchasing clothing and clothing, it is necessary to consider this factor. When purchasing silk fabrics, the size of the fabric is preferably increased by 8% to 10%. Such as a one-meter-long silk clothing, plus the shrinkage rate should be one meter a length is better, especially after the silk double watershed will appear between the latitude and longitude shrinkage phenomenon, so when choosing silk clothing must increase a file size is appropriate, If you wear a shirt with a size of 64 x 96, it would be nice to buy a silk double crinkly shirt with a size of 66x98.

The selection of silk clothing and clothing must be based on the principle of wearing large and small clothes. It is not only comfortable for proper fattening of clothing, but also highlights the characteristics of free, soft and luxurious silk clothing.

There are many varieties of silk clothing, and people should choose according to different clothing styles, such as dresses, cheongsams, or national costumes, to reflect the elegance, lightness and elegant beauty of silk clothing.
