Materials of down jackets
Down
Small pinnae and feathers mixture. Duck and goose feathers are mostly used, and there are two types of down: gray and white, with the white one being the better.
The quality of down jackets is related to the amount of down filling and down content. The amount of down filling refers to the weight of down in a down jacket, expressed in grams. If the amount of down filling is small, the warmth retention will be poor. Down content refers to the down content in down, expressed as a percentage. The higher the down content, the better the quality.
Coated fabric
Choose silk, cotton, Fabrics such as cotton and polyester are rolled and pressed to reduce the gaps between the warp and weft yarns, and then coated with polymer slurry to form a cross-linked transparent film covering layer with the fabric to close the gaps between the warp and weft yarns.
Some add fluorophosphorus resin or silicone waterproofing agent to the coating slurry to make the fabric anti-lint and anti-water seepage.
Basic requirements for common down jacket fabrics
Windproof and breathable
Breathability is an important evaluation aspect of the comfort of winter clothing.
Anti-leakage
There are three ways to enhance the anti-leakage of down fabrics.
1. Cover the base fabric with a film or coating 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.
2. The high-density fabric is processed through post-processing to improve the lint-proof performance of the fabric itself.
3. A layer of anti-flannel cloth is added to the inner layer of the down fabric. The quality of the anti-flannel cloth will directly affect the quality of the entire garment.
Lightweight and soft
Soft fabrics will enhance the comfort of elderly people wearing down jackets, which are already bulky. On the other hand, thin and soft fabrics help to better utilize the fluffiness of down and improve warmth retention.
Fabric design of winter down jackets for the elderly
Down design in down jackets
Down jackets are light, soft and warm. These characteristics are largely determined by The content and quality of down in down jackets.
Based on the average winter temperature in recent years (generally around minus 10 degrees) and the physiological characteristics of the elderly who are not cold-tolerant, we choose white duck down with a down content of 80% and a down filling of 180g~250g.
Fabric design
Made of pure cotton PU coated fabric with TTU isolation layer. It has a silky smooth, delicate and tight feel.
Pure cotton material is easy to absorb sweat and breathable. The PU coating is not easy to wrinkle, has excellent elastic recovery function and can effectively prevent lint leakage. The biggest features of TTU isolation layer are heat absorption, breathability and moisture conduction. Although the fabric is thin, the snow-white down inside is not visible at all.
After the rolling and weaving process, the fiber filaments of the TTU isolation layer are extremely tightly combined. At the same time, the porous structure of the fiber can effectively conduct moisture and breath to the inside and absorb sunlight to the outside. Therefore, it has extraordinary windproof, warm and breathable properties.
Lining design
Using polyester taffeta woven from fine denier polyester silk imitation silk. A thin polyester fabric.
Using fine-denier polyester filaments that increase the moisture absorption and breathability of the fabric, weaving it into a fabric with a silk-like appearance. Bright and shiny color, smooth to the touch.
The warp and weft of this fabric are made of semi-matt fine-denier polyester yarn FDY50D/48F, which makes the fabric soft and lustrous and increases dyeability and drape.
It is made of plain weave interwoven on a water-jet loom according to 290T specifications, which is the specification to prevent down leakage. The gray fabric undergoes processes such as relaxation, desizing, alkali reduction, dyeing, soft shaping and calendering. The special finishing process makes the fabric have the characteristics of uniform texture, thin and breathable, soft and delicate surface, stiff and easy to iron, and anti-velvet leakage. It is the ideal lining material for making winter down jackets.
