The fabric of down jacket should be cashmere-proof, windproof and breathable, especially cashmere-proof. The cashmere resistance depends on the yarn density of the fabric used. At present, the main products on the market are nylon taffeta and TC cloth. Generally, the yarn count density is above 230T, and 250T is the best. It is difficult to ensure that the fluff is not drilled below 230 t. When identifying the fabric, first look at its thickness. Generally, thin fabrics are thin and thick fabrics are dense. The second is to shoot by hand. If the fluff flies out, the density must be below 230T; Thirdly, hold a certain part of the clothes and rub it slightly (with the consent of the salesperson, of course). If there is no fine wool, the density should be 250 t; Because the thick nylon fabric has a layer of paint, its treatment should be bright, smooth and uniform. (2) Look at cashmere. Down jackets are mainly filled with duck down and goose down. In order to reduce the cost, some down jackets are made of shredded or shredded chicken. The so-called chicken shredding is to tear the hair off the chicken feathers to remove the hair stalks, and the broken wool is the broken powder of the hair stalks. It's really hard to tell the quality of down jackets, but it's not without rules. Here are some ways that consumers may wish to try. First of all, distinguish from the thickness and weight of down jackets. Two down jackets with different thicknesses look very thick, but they are not very heavy. Its cashmere content is generally high and its quality is good; On the contrary, thin and heavy, there must be problems. Generally speaking, the weight of minced chicken is greater than that of minced duck and goose. Second, distinguish from the cumbersome. Put the down jacket on the table and knead it with your hands. High-quality cashmere can overwhelm a very thin degree, and immediately return to its original state after being released, and it is as fluffy as ever; Inferior cashmere can't be pressed very thin, and it will recover slowly after being released. Thirdly, there is a supreme recognition from the thickness and length of hair stalks. According to the current specifications and standards of domestic product fillers, the cashmere content is 50%, half of which is dandelion-like velvet flowers and the other half is 2-inch-long fine wool pieces. In other words, a certain amount of hair stalks are allowed in the filler. However, if you feel no stalks, you can conclude that the chicken is torn or crushed. If you pat the broken velvet by hand, dust is likely to appear. In addition, clothes filled with shredded wool may agglomerate after washing, unlike pure ducks and geese, which will swell again after being patted evenly. (3) Looking at the style, down jackets require high workmanship, and a slight negligence will affect the quality. Sewing times should be appropriate, too thin is easy to wear, too dense is easy to make the cloth incomplete, affecting bulkiness and warmth. Because of pinholes, some flying bands will inevitably come out, but if longer and longer tops are drilled continuously, it will be a quality problem. (4) Look at the quality of raw and auxiliary materials of down jackets, which directly affects the wearing effect. The tightness of the metal buckle should be appropriate. Generally speaking, the zipper is a cast zipper, and the track should be smooth. When choosing, we should focus on testing its rebate effect, that is, the zipper does not naturally drop after being pulled for a period of time. If you choose high-quality down jacket, you should know the relevant knowledge and have some experience. Then the satisfactory choice depends on the differences of consumers' body shape, skin color, age, culture and hobbies. Generally speaking, fat people wear dark colors, thin people wear light colors, and dark skin wears bright colors. Intellectuals should wear dignified, generous and steady styles. As for personal hobbies, as the saying goes, wearing a hat has its own advantages, and you can choose according to your own situation and requirements. ◎ Put your nose close to the down jacket and smell it carefully. If there is obvious fishy smell or peculiar smell, it means that the down raw materials used have not been strictly processed and disinfected. ◎ Touch the down jacket with your hand to test its softness. If there are too big and too thick long wool, short broken wool, etc. This down jacket is of poor quality. ◎ Tap the down jacket gently with your hand to see if there is dust overflowing at the seam. If dust overflows, it is a fake made of broken wool or gray sand wool. ◎ Rub the front and back of the down jacket with both hands to see if there is fluff coming out. If fluff is drilled out, it means that the fabric or lining used has poor or no anti-drilling performance. 1, look at the amount of cashmere. Generally, it is better to choose the kind with more cashmere. You can put the down jacket on the box and pat it with your hands. The higher the fluffy degree, the better the cashmere quality and the more cashmere content. 2, look at the velvet color. Down is divided into pure white down and floral down. If you choose a light-colored down jacket, you should choose pure white down inside, otherwise you will feel dirty. 3. Look at this cloth. Avoid down jackets with various fabrics. There is a layer of wax on the surface of cotton wool fabric, which has strong heat resistance but poor wear resistance; Velvet-proof nylon yarn fabric is wear-resistant and durable, and has good velvet-proof property, but it is afraid of scalding and sun exposure. Generally speaking, it is better to buy a down jacket made of TC fabric. 4. Look at the workmanship. It depends on whether the suture is firm and there is no leakage; Whether the zipper and copper buckle are complete and smooth; Whether the interior of the down jacket is flat or not.
