Down jacket index requirements

⑴ Downfilling capacity: Downfilling capacity is not an indicator of down quality, it refers to the weight of all down filled with a down jacket. Generally, the filling amount of outdoor down jackets is about 250-450 grams depending on the target design.

⑵ Down content: Down content is the proportion of down in down, generally expressed as a percentage. The down content of outdoor down jackets is generally above 80%. The data shows that the down content is 80%, and feathers account for 20%.

⑶. Fill power: Fill power is an important indicator to measure the warmth of down. If the space occupied by an ounce of down is 600 cubic inches, the bulkiness of the down is called 600. The higher the bulkiness of the down, it means that the down under the same amount of down filling can fix a larger volume of air layer for heat preservation and heat insulation, so the warmth of the down is better. The bulkiness is not a rigid indicator in China, and the relative error of measurement is also relatively large.

Fabric requirements

⑴, windproof and breathable: most outdoor down jackets have a certain degree of windproof. Breathability is a unified requirement for outdoor clothing, but many travel friends tend to ignore the importance of breathability of down jacket fabrics. The result of an airtight down jacket on the mountain is often fatal.

⑵. Anti-fleece: There are three ways to enhance the anti-fleece of down fabrics. One is to cover the base fabric with a film or coating. The film or coating is used to prevent velvet leakage. Of course, the first prerequisite is that it is breathable and will not affect The lightness and softness of the fabric. The second is to pass the high-density fabric through post-processing to improve the velvet resistance of the fabric itself. The third is to add a layer of anti-flannel cloth to the down fabric. The quality of the anti-flannel fabric will directly affect the quality of the whole garment.

⑶. Lightweight and soft: In today's lightweight equipment, the lightness of the fabric of the down jacket will directly affect the overall weight of a down jacket, and the soft fabric will enhance the comfort of the down jacket for the down jacket, which is itself bloated. On the other hand, light and soft fabrics help to better play the bulkiness of the down, so the warmth retention will be higher.

⑷ Waterproof: mainly for professional down jackets, which are worn directly outside in a cold environment. The fabric of down jackets should be used directly instead of jackets.

Common fabrics and characteristics of down jackets

The surface layer of the down jacket is mainly made of coated fabrics. The coated fabrics are made of high-density warp and weft yarns, such as silk, cotton, cotton and polyester, which are pressed to reduce the gap between the warp and weft yarns, and then coated with polymer slurry to make it A transparent film covering layer that is interlinked with the fabric to close the warp and weft gap of the fabric. Some add fluorine-phosphorus resin or organic silicon water-proofing agent in the coating slurry to make the fabric have anti-dew and anti-seepage properties.

⑴羽绒填充量：羽绒填充量并不是羽绒质量的指标，它是指羽绒服中所有羽绒填充物的重量。通常，根据目标设计，室外羽绒服的填充量约为250-450克。

⑵羽绒含量：羽绒含量是羽绒在羽绒中的比例，通常以百分比表示。户外羽绒服的羽绒含量一般在80％以上。数据显示，羽绒含量为80％，羽毛占20％。

⑶。填充力：填充力是衡量羽绒保暖性的重要指标。如果一盎司羽绒所占据的空间为600立方英寸，则羽绒的蓬松度称为600。绒头的蓬松度越高，这意味着在相同数量的羽绒填充下的绒毛可以固定更多的空气保温和隔热层，因此羽绒的保暖性更好。在中国，体积并不是一个严格的指标，并且测量的相对误差也相对较大。

面料要求

⑴，防风透气：大多数户外羽绒服都有一定程度的防风。透气性是户外服装的统一要求，但是许多旅行朋友倾向于忽略羽绒服面料透气性的重要性。在山上不透气的羽绒服的结果通常是致命的。

⑵。防绒：有三种方法可以增强羽绒织物的防绒性。一种是用薄膜或涂层覆盖底布。薄膜或涂层用于防止天鹅绒泄漏。当然，第一个前提条件是它要透气且不会影响织物的轻度和柔软度。第二个方法是使高密度织物经过后处理，以提高织物本身的抗绒毛性。第三是在羽绒织物上添加一层防绒布。防绒布的质量将直接影响整个服装的质量。

⑶。轻巧柔软：在当今的轻型设备中，羽绒服面料的轻便度会直接影响羽绒服的整体重量，而柔软的面料将提高羽绒服的羽绒服的舒适度，而羽绒服本身就是ated肿。另一方面，轻巧柔软的面料有助于更好地发挥羽绒的蓬松度，因此保暖性更高。

⑷防水：主要用于专业羽绒服，在寒冷环境中直接穿着在外面。羽绒服的面料应直接代替外套使用。

羽绒服的常见面料和特点

羽绒服的表面层主要由涂层织物制成。涂层织物由高密度的经纱和纬纱制成，如丝绸，棉，棉和聚酯，将其压制以减小经纱和纬纱之间的间隙，然后涂上聚合物浆料使其成为透明膜与织物互连的覆盖层，以闭合织物的经纱和纬纱。有些在涂料浆料中加入氟磷树脂或有机硅防水剂，使织物具有防露和防渗性能。
