① Down: a mixture of small pinnae and down (also known as down). The former is called feather, and the latter is called velvet. The feathers of ducks and geese are mostly used, and after selection and washing, the small feather flakes and down are separated to be used as flocs for down jackets.

There are two kinds of down, gray and white, and the white one is better. The quality of down jackets is related to down filling and down content.

Down filling refers to the weight of down in a down jacket, expressed in grams, less down filling means poor warmth retention; down content refers to the content of down in down, expressed as a percentage, higher down content means better quality.

② Coated fabrics are made of silk, cotton, cotton polyester, and other fabrics with a high density of warp and weft yarns. After calendering treatment, the gaps between warp and weft yarns are reduced and then coated with polymer slurry to form an interlinked transparent film with the fabric. Overlays to close gaps in fabric warp and weft. Some add fluorophosphorus resin or organic silicon waterproofing agent to the coating slurry so that the fabric has the performance of dew-proof and water-proof.

Down jacket fabric

Common down jacket fabric basic requirements

(1) Windproof and breathable: Most down jackets have certain windproof properties. Breathability is an important evaluation aspect of winter clothing comfort.

(2) Anti-down: There are three ways to enhance the anti-down properties of down fabrics
One is to cover the base fabric with a film or coating to prevent fleece leakage. Of course,

the first prerequisite is breathability, and it will not affect the lightness and softness of the fabric.

The second is to improve the down-proof performance of the fabric itself through the post-processing of high-density fabrics.

The third is to add a layer of fleece-proof cloth to the inner layer of the down fabric. The quality of the fleece-proof cloth will directly affect the quality of the whole garment.

(3) Thin and soft: In today's lightweight equipment, the lightness of the fabric of a down jacket will directly affect the overall weight of a down jacket, and the soft fabric will enhance the comfort of the elderly wearing down jackets for the bloated down jacket itself. comfort. On the other hand, the light and soft fabric help to give full play to the bulkiness of the down, so the warmth retention will be higher.

Winter down jacket fabric design

1. Down design in down jackets

The down jacket has the characteristics of lightness, softness and warmth, and these characteristics largely depend on the content and quality of down in the down jacket.

The average temperature in the winter area (generally around minus 10 degrees) and the physiological characteristics of the elderly who are not resistant to cold are selected: white duck down with 80% down content and 180g~250g down filling.

2. Fabric Design

It adopts pure cotton PU-coated fabric with a TTU isolation layer (the fiber yarn density of the pure cotton base fabric is 200T, plain weave). The pure cotton PU-coated fabric is silky smooth, delicate, and tight to the touch. The pure cotton material is easy to absorb sweat and has good air permeability, and the PU coating makes it difficult to wrinkle. It has an excellent elastic recovery function and can effectively prevent velvet from leaking. The biggest feature of the TTU insulation layer is heat absorption, breathability, and moisture conduction. Although the fabric is thin, you can't see the snow-white down covering it at all. After the rolling and weaving process, the fibers of the TTU isolation layer are combined extremely tightly, and at the same time, the porous structure of the fibers can effectively conduct moisture and air to the inside and absorb sunlight from the outside. Therefore, it has extraordinary windproof, warm-keeping, and breathable properties.

3. Lining design

It adopts polyester taffeta woven from fine denier polyester silk imitation silk. This polyester taffeta is a kind of all-polyester thin fabric, which is woven with fine denier polyester filament (to increase the hygroscopicity and air permeability of the fabric) to form a fabric with a silk appearance style, bright and bright color, and smooth to the touch.

The warp and weft of the fabric are made of semi-dull (soften the luster of the fabric, increase the dyeability and drapability) fine-denier polyester filament FDY50D/48F (referring to this 75-denier fully stretched fine-denier polyester filament is composed of 48 monofilaments ) as raw material, plain weave is interwoven on a water-jet loom according to the specifications of 290T (to prevent leakage of down). Dyeing, soft setting and other processes and calendering special finishing process, the fabric has the characteristics of uniform texture, thin and breathable, soft and delicate surface, crisp and non-ironing, and anti-leakage of fleece. It is an ideal liner lining for winter down jackets.
