Characteristics And Indicators Of Down Jacket Fabrics

The down jacket has the characteristics of light, soft and warm, and these characteristics are largely determined by Down fabric And feather down content. Feather and down clothing materials are mainly feather and coated fabrics, feather clothing material characteristics and indicators.

Down clothing is mainly made of down and coated fabrics. Eiderdown: a mixture of pinna and velvet (also called Duffy). The former is called feather, and the latter is called velvet. The hair of duck and goose should be used to separate the pinna and cashmere into the floc of the down coat. There are two kinds of duvet, and the white one is the best. The quality of down garment is related to the amount of cashmere and the amount of cashmere. The filling weight refers to the down weight of a down garment, which is generally expressed as 250 grams, with less filling and less warmth. The amount of cashmere is about 50 to 80% in percentage. The quality is good with high content of cashmere. Because the cashmere can make human body heat not easy to lose and feel soft, but when pressed and wet, it is not easy to bulge in time, while the small pinna can make the clothes bulky and bulge up to keep more air in the clothes, which helps keep warm, but the small pinna is more, the heat is easy to dissipate, and there is a sense of hair stalks. So velvet and pinna must be well proportions and proportions.

　　 Coated fabric The warp and weft yarns, such as silk, cotton, cotton and polyester, are selected to shrink the gap between warp and weft yarns by rolling and pressing. Then they are coated with polymer paste so as to form a transparent film covering layer with the fabric to seal the warp and weft gap of the fabric. Some fluorinated phosphorus resins or silicone waterproof agents are added into the coating slurry, so that the fabric has the properties of dew proof and water penetration resistance. In 1980s, there was already a special super high density fabric without coating, which also played the role of dew proof, waterproof and breathable. Nonwovens and deep processing technology and equipment: spunbonded, melt blown, Spunlaced, needle punched, dry paper (expanded paper), sewing, heat bonding, chemical bonding, carding, netting, fiber pre-treatment and other non-woven material equipment and production lines; for down fabrics, fabrics are divided into two categories: hard and soft. Polyester, polyester and cotton fabrics are hard and smooth. Silk silk poplin and nylon are soft and comfortable.

Feather and down clothing production material - Feather index introduction. Down filling: the amount of filling is not an indicator of feather quality. It refers to the weight of a down garment filled with all down. According to the target design, the filling amount of the general outdoor down jacket is about 250-450 grams. Down content): the percentage of cashmere is the proportion of down, which is usually expressed in percentage. The down weight of outdoor down garments is generally over 80%. On the surface of the data, the content of the cashmere is 80% and that of the feather is 20%.

　　 Down Fill power: fluffiness is an important index for measuring the degree of thermal insulation of the down. It refers to the volume of cubic inch of each ounce (30 grams) down under certain conditions. It will become a new engine for future economic development. Our country will also cultivate strategic emerging industries as the focal point for the development of modern industrial system. Industrial textiles are closely related to new material industries, but also new energy sources, energy saving and environmental protection. The space occupied by an ounce of eiderdown is 600 cubic inches, which means the fluffiness of the down is 600. The higher the bulkiness of the down is, the more eiderdown of the eiderdown can be fixed with a larger volume of air layer for thermal insulation and heat insulation, so the warmth of the down is better. Bulky degree is not a rigid index in China, and the relative error of measurement is also large.
