　　 pajamas Common sense on fabric identification of household clothes and maternity clothes

（1） Characteristics of several fabrics

1. Cotton:

Advantages: comfortable to wear, sweat absorbing and breathable, soft, warm, anti sensitive, easy to clean, not easy to pilling.

Disadvantages: easy to wrinkle, shrink, deform and fade.

2. Hemp:

Advantages: natural fabric, comfortable, light and breathable.

Disadvantages: easy to wrinkle, not neat, poor elasticity, and skin tingling when wearing.

3. Polyester:

Advantages: chemical fiber fabric, easy care, neat.

Disadvantages: poor permeability, easy to generate static electricity, and difficult to dye.

4. Silk

(1) Silk: soft luster, soft and delicate feel.

(2) Rayon: metallic luster, rough and hard feel.

(3) Silk: antistatic, hygroscopic, fine and soft, warm in winter and cool in summer

Advantages: smooth and soft, good texture, bright colors.

Disadvantages: difficult to take care of, easy to wrinkle and shrink.

（2） Identification method

1. How to choose a satisfactory hemp spin Quality?

(1) Identification of pure hemp fabric: pure hemp fabric has a fine, clean and bright appearance, and its texture is clearly visible. The yarn count is thicker than cotton, wool and yarn chemical fiber fabrics, and the surface of the fabric is evenly distributed with roving count and slub yarn, which are the special style of linen fabrics. Generally speaking, pure linen fabric has a rough and hard feel and poor softness. If you shake the fabric in your hand, it will feel good. However, if you touch the fabric tightly and release it, the fabric will have many creases, with different sizes of creases. Some pure hemp fabrics also have some natural small bumps on the surface, which is called "hemp material". It is made of natural hemp. If the yarn is drawn from the selvage, it can also be distinguished from other fibers by its fineness (thicker) and evenness. When identified by combustion method, hemp fiber is combustible and gives off the smell of vegetation.

(2) Identification of genuine and fake hemp fabrics: genuine hemp fabrics are woven with natural hemp fibers, while fake hemp fabrics are mostly imitation hemp fabrics or blends woven with artificial fibers and synthetic fibers. Due to different raw materials, their wearability varies greatly. On the surface, real linen fabrics are only slightly different from fake linen fabrics in yarn count. In terms of color, linen like fabrics generally have bright colors, rich patterns and colorful patterns; However, real linen fabrics tend to be light in color due to their weak color absorption ability. Hemp like fabric or blended fabric has a clean hand feel and good wrinkle resistance. When you grip the fabric tightly with your hands, you can loosen the fabric with little or no wrinkles. When using burning method to identify fabrics, linen like fabrics do not have the burning herb smell after igniting pure linen fabrics. If you go to a store to buy, you may want to look at the product label before buying. The number with "R" in front of it is pure linen or cotton linen fabric, "TR" is polyester linen blended fabric, and "RT" is linen polyester blended fabric.

2. Silk Rayon Identification with silk satin

(1) The silk satin is made of natural silk. The silk surface is smooth and bright, with exquisite hand feel and elegant feeling. It is highly breathable and does not feel stuffy;

(2) The rayon fabric feels rough and hard, heavy and stuffy.

(3) . After falling into the water and drying, the silk satin has a large shrinkage rate of 8% - 10%; The shrinkage rate of rayon fabric is small, only about 1%.

(4) After burning, the effect is different. The silk fabric will smell of protein after being burned. Rub it with your hands, and the ashes will be in powder state; The flame of rayon fabric burns fast. After the odor free flame is extinguished, touch it with your hand. The fabric feels hard.

3. Identification of silk and nylon fabrics

(1) . Nylon fabrics are different from silk fabrics in gloss. Nylon filament fabrics have poor gloss and look like a layer of wax on the surface.

(2) . The handle is not as soft as silk, and it feels stiff.

(3) When you grip the fabric with your hands and release it, although the nylon fabric also has creases, the creases are not as obvious as rayon, and it can slowly recover to its original state. The polyester fabric is crisp and traceless, and the fabric is basically crease free.

(4) . Tested by the filament drawing method, the nylon filament is not easy to break, while the real silk is easy to break, and its strength is far less than that of nylon.

4. Identification of Silk and Chemical Fiber Blends

When you choose this kind of fabric, you should look at its product label and ask about the content of ingredients. Of course, fabrics with more silk content are comfortable to wear and slightly expensive. For example, for silk/viscose blended fabrics, the amount of viscose fiber is usually 25-40%. Although this kind of fabric is cheap, breathable and comfortable to wear, the anti wrinkle performance of viscose fiber is poor. When the fabric is clenched by hand and released, more viscose fibers (rayon) are found in the pleats, and vice versa. Polyester/silk blended fabric is also a kind of blended fabric commonly seen in the market. The consumption of polyester is 50~80%, and 65% polyester and 35% spun silk are mostly used in China. This fabric has good softness and drapability, and is also strong and wear-resistant. Moreover, polyester has the ability to recover creases and maintain pleats, which changes the performance of pure polyester fabrics. The feel and appearance of this fabric naturally take into account the characteristics of the two fibers, but polyester fabrics have a little more performance.

5. The following simple methods can be used to identify true and false colored cotton products:

(1) Natural colored cotton has only brown and green colors of dark and light, and there is no formal product of other colors at present.

(2) The natural colored cotton is usually not bright in color, because there is a layer of waxy substance and corky protective layer outside the fiber, so the appearance is dim and soft. However, after water washing (especially hot water plus alkali), the brightness will increase due to the decrease of cork quality. If exposed to strong light for a long time, the wax in the fiber will turn yellow due to photochemical reaction.

(3) If the fiber cross section is observed with a microscope, the natural colored cotton should be dark inside and light outside in the same color, while the fiber cross section dyed with chemical dyes is dark outside and light in the center.

(4) The commodities of natural colored cotton products shall be provided with a certificate with the certificate number of HIBZ-30-001. The price of natural colored cotton products is generally high, so you should be careful when purchasing.

6. Identification of cotton and chemical fiber blended varieties

The pure cotton fabric has a soft feel, and the surface of the fabric is not smooth enough. The polyester cotton blended fabric has a bright and shiny surface, and the feel is very clean and smooth. It is not easy to crease when the hand is tight and loose; Fiber rich cloth and artificial cotton cloth are bright in color, smooth, soft and smooth in handle: artificial cotton has loose tissue and poor shape retention; Vinyl cotton cloth is slightly dark in color, uneven in luster, soft in hand feel and rough in surface. Like rich fiber cloth and artificial cotton, it is easy to crease.

（3） Finally, let's summarize how to use combustion method Identify fabrics ?

Cotton: It is flammable, catches fire quickly, has paper burning smell, and appears fine and soft gray black floccule after burning.

Hemp: The burning characteristics are similar to that of cotton. It has a burning smell of paper. After burning, it appears fine and soft gray white flocculent.

Wool: It burns slowly after the fire. It has the smell of burning hair. It is black coke and fragile after burning.

Polyester (dacron): It is easy to melt when burning, and continues to burn after leaving the fire, with thick smoke, but the melted matter will not fall down, with fragrant smell, and it is hard, black, and bead shaped after burning.

Acrylic fiber (synthetic wool): melted and burned, with a spicy taste, and the combustibles are small black hard balls.

Nylon (nylon): The flame is nearly melted, and then self extinguishes. It tastes like celery and becomes a hard yellowish brown block after burning.
