Experts Interpret Down Garments

　　 Down So far, the world's best natural materials for human warmth, after washing, drying, grading and other processes, has been used as a natural material. clothing The filling material is made into down garments. Down garments are of excellent quality such as light weight, soft texture, superior thermal insulation and easy maintenance.

China is a large country with down production and export. Data show that China accounts for more than 70% of the world's total down production.

Focusing on the concerns about the daily purchase and use of down garments, Ms. Zhang Yulian, a specially invited expert of China Textile Economic information network, has done an interpretation for us to help us understand the characteristics of down products and learn how to choose and maintain them. Down Jackets 。

　 1, how does the down feather keep warm?

The eiderdown is three-dimensional structure, so it can "expand". Each cluster of down silk has more air than other materials under the same weight. There are about 70 thousand filaments per gram of eiderdown. These filaments overlap and interweave, forming a protective layer that can heat and heat through fixed air.

The plump layer of birds is full. By keeping the static air containing birds' body heat, the temperature difference between the body and the environment of birds is isolated, so as to ensure that birds can survive the cold winter safely.

　　 2. What quality indicators do you need to pay attention to?

The current standard of down garments in China is GB/T 14272-2002 "down garments", and the relevant mandatory standards are: GB 18401-2003, "basic safety technical specification for national textile products" and GB 5296.4-1998 "instructions on the use of textiles and clothing for consumer goods."

1, down garments must first meet the requirements of mandatory standards, such as formaldehyde content, pH value and banned decomposable aromatic amine dyes. It also tests light fastness, washability, sweat resistance, water resistance and color fastness to rubbing, and yarn slippage properties.

2. According to the standard of down garment, the nominal percentage of cashmere can not be less than 50%. The higher the percentage of wool, the better the warmth of the same weight. The standard provides that the allowable deviation of cashmere percentage is 3%.

3, the air permeability and moisture permeability of the surface and lining materials are an index that can not be considered when producing down garments. Sometimes, in order to prevent the surface of the down pile from being drilled, the enterprises use completely airtight materials, so that the wearers can not discharge the sweat from the body surface in time, affecting the wearing comfort. There is no definite requirement in this standard. Enterprises should adopt suitable materials according to the target of the product.

4, filling amount: indicate the amount of filling, the same down the down rate of the down, the more filler, the more warm. The allowable deviation of the nominal filling amount is 5%.

5. The fluffiness of down. This is an index that can best reflect the quality of down. It is directly related to the amount of cashmere. It has high flush content and good fluffiness.

6, oxygen consumption, cleanliness, odor, residual ester rate and microorganisms are directly related to the processing technology of down. If the eiderdown is not noticed in the cleaning process, it may exceed the standard.

7, special note: for children aged two and below, they also have to comply with the relevant requirements of category GB products in the basic safety technical specification for national textiles products "GB 18401-2003".

3, how to buy down garments?

Because of its strong thermal insulation and light texture, down garments are popular with people in cold regions and are commonly used by polar visitors.

The purchase of down jacket is mainly based on the needs of users, first of all, choose a down jacket that suits oneself, and then choose a down quality garment with good quality.

General city wintering: you can choose to wear comfortable, warm, fashionable and generous down jacket.

Work or travel in cold areas: it is best to wear long down garments, fabrics that are more wearable, and have more pockets for personal belongings.

For example, ordinary climbers should pay more attention to the permeability of clothing in addition to paying attention to the thermal insulation of the down jacket, because they may sweat a lot during exercise, if they can not be discharged in time, they may cause serious consequences. The so-called "assault clothing", which is popular in the market, comes into being in order to adapt to this demand. Therefore, fabrics require waterproof, windproof and breathable. You can also use the liner down jacket to wear the outer garment.

Long distance travel: generally on the road for a long time, the environment that passes through also has very big difference, that is to say, may appear in some places need the down jacket to keep out the cold, and may wear T-shirt in some places. Therefore, the requirement for down clothing is small and light weight. It can be compressed in a corner of the backpack when it is not needed.

The quality of down garments can be selected according to the following steps:

A look: whether there is a registered trademark, product instructions and related content is complete, such as factory name, factory site, fabric material content, feather and down, the amount of filling, indicators, washing marks, quality levels, the implementation of standard code, etc.; look at the appearance of products, sewing quality; see accessories: a down jacket, there are many accessories, such as zippers, metal buckles, whether it is beautiful, smooth, tight fitting.

When choosing the down garment, besides the amount of cashmere and the quality of filling material (the amount of filling), the down clothing with the same type and the same amount of cashmere, the more the filling amount of the stuffing, the better the thermal insulation of the down jacket. The down coat is large, round and warm.

Two: press down the down jacket and press down the down garment, then release your hand to see if the down jacket can rebound quickly and restore to its original state. Rapid rebound, restore the original state, indicating that the fluffy degree of down. If there is a low content of wool and a certain amount of wool or crushed wool, the resilience will be poor, and feel that the down jacket will feel heavy in the hand.

Three touch: touch down the down garment by hand and test its softness and integrity. Feather stalk should be soft and hairy, but not thick. If there is no woolen stalk, it may not be down. But Mao Gengtai has less amount of cashmere, and has lower quality and warmth.

Four Pat: beat down eiderdown clothes, see whether there is dust overflow at the stitch, and whether there is fluff out. Make a clap of the down jacket and shake it hard. If a lot of down silk is drilled out, the fabric that may be used will be badly damaged, or the stitch will be too big. Because of the smoothness of down, occasionally a small amount of velvet spills from the seam is normal.

Down clothing can not be duffed, but also has a certain degree of permeability, such as the down coat fabric, lining, gallbladder permeability is poor, first, the water vapor in the process of clothing is not easy to distribute, causing moisture and feel uncomfortable, not warm. Two, it is not easy to dry after washing. The above two factors will make the eiderdown produce different degrees of deterioration under the condition of damp, or breed microbes, and stink.

Five sniff: nose close to down jacket, sniff and smell, and then compare with the normal down garments, check whether there is fishy smell or smell, avoid buying the pungent merchandise. But because feather down is collected from animals, it is normal to have a subtle feather down.

Accessories: a down coat has many accessories, such as zippers, metal buttons, etc., whether it is beautiful, smooth and elastic. {page_break}

　　 4, how to wash and maintain down garments?

Down garment is not suitable for dry cleaning. Because regular dry cleaning is completely soaked in dry cleaning agents (organic solvents), dry cleaning agent into high-density down fabric, but often difficult to volatilize clean, smell bad, residual dry cleaners continue to release may also cause harm to the human body. In addition, the dry cleaning agent has a strong dissolution effect on oil, and it also removes the protective grease contained in the eiderdown itself, destroys the characteristics of the feather itself, and reduces the flexibility of the eiderdown. It is easy to break brittle and seriously affect the fluffiness and warmth retention.

Down garments should be washed. Because the density of the down fabric is large, washing clothes with a washing machine will drum up and float on the water surface, resulting in uncleanly washing. Before washing, wash the special dirty parts first, and squeeze the clothes into the water. The water temperature should not be too high to prevent the fabric from wrinkling or decoloring until it is soaked. Put the soaked clothes in the washing machine, add detergent, and wash the powder. The amount of washing powder is not too much. Most of the detergent contains whitening agents. Too much amount of them will make the dark clothing form white dots and white stripes. After drying, not only will there be soap stains, but also the fluffiness will be affected by inhaling too much washing powder in the down, which will greatly reduce the warmth retention performance. It is necessary to dissolve the washing powder thoroughly and then pour it into the washing machine. After washing, it can dehydrate, then put it in the sun or dry in the ventilating place. Once dry and pat gently, the down will restore the original fluffy and soft state.

Before collection, down garments must be washed and dried. As for daily storage, please choose dry and cool environment as much as possible, and add a small amount of moth proofing agent.
