Problems solved by technology

[0003] Chinese patent CN200610154665.3 discloses a down jacket with a four-layer structure. The down jacket effect is achieved by adding bile cloth layers, fabric gluing, and overcoating. This method is complicated in process, and the resulting down jacket is relatively thick and has an overall aesthetic effect. Poor; in addition, Chinese patent CN200610052110.8 discloses a production method for seamlessly fitting waterproof and anti-drilling down jackets, but it does not solve the elastic problem of the fabric, and the wearing comfort cannot meet people's needs

Embodiment 1

[0017] The whole process of making the whole down jacket mainly includes the following steps:

[0018] Step 1. After sticking a layer of polyurethane elastic film with breathable and moisture-permeable effect on the inner side of the warp knitted fabric, the fabric transverse density: 46 threads / inch, vertical density: 96 threads / inch, door width: 130cm. Among them, the thickness of the film is 0.01mm, the warp elongation of the film fabric is 14.3%, the weft elongation is 78.6%, and the weight is 104g / m 2 , Peel strength: 26.46N / cm in the transverse direction and 28.44N / cm in the longitudinal direction.

[0019] Step 2. Carry out plate making and verification of the down jacket.

[0020] Step 3. Do laser cutting and auxiliary cutting. Among them, laser cutting must draw a pattern in the computer, set the energy and speed of the laser cutting machine, and transmit the pattern to the laser cutting machine for cutting.

[0021] Step 4. On the body parts and sleeves to be fitt...

Embodiment 2

[0025] The whole process of making a sleeveless and capless down jacket mainly includes the following steps:

[0026] Step 1. After sticking a layer of polyurethane elastic film with breathable and moisture-permeable effect on the inner side of the weft knitted fabric, the fabric transverse density: 58 threads / inch, vertical density: 96 threads / inch, door width: 133cm. Among them: the thickness of the film is 0.01mm, the warp elongation of the film fabric is 17.8%, the weft elongation is 86.7%, and the weight is 115g / m 2 , Peel strength: 5.531N / cm in the transverse direction and 5.777N / cm in the longitudinal direction.

[0027] Step 2. Carry out plate-making and verification of the sleeveless down jacket.

[0028] Step 3. Follow the cardboard for normal cutting.

[0029] Step 4. Iron and fix the fabric and lining on the two sides of the strip-shaped tape on the body part to be fitted, and then heat press with a seamless heat press. During hot pressing, the temperature of th...

Abstract

The invention discloses a down jacket and a production method thereof. The production method comprises a whole process from shell fabric forming to finished product forming. The production method comprises the following steps of: after sticking a breathable and moisture-permeable polyurethane film to the inner side of a warp-knitting or weft-knitting knitted fabric, carrying out laser cutting or ordinary cutting, at least carrying out a seamless plying-up process on a bodice part, then, filling eiderdown, and carrying out auxiliary sewing to form a knitted seamless down jacket. The knitted seamless down jacket can be next to the skin after being worn, is elastic and has a breathable and moisture-permeable function, so that the motion of a human body is greatly facilitated and the comfort is improved; furthermore, the advanced seamless hot-pressing technology is adopted, so that the sewing stitches are greatly reduced, and the problem that the eiderdown comes out from the sewing thread is solved; and the whole jacket is upgraded in both appearance and function.

Description

technical field [0001] The invention relates to a knitted down jacket and a production method thereof. Background technique [0002] Most of the down jackets currently on the market are made of woven fabric layers, down jacket anti-down lining, lining and filler down. It is formed by flat sewing with polyester thread or nylon thread between the fabric, gall and lining, so that the down jacket made is easy to drill down in places with stitches, thus affecting people's wearing comfort and aesthetics. Moreover, the elasticity of the woven fabric is small, and it must have a certain degree of looseness to be suitable for various movements of the human body. Such a down jacket also looks very bloated. With the current people's demand for the functionality and perfection of down jackets, the previous down jackets can no longer meet people's needs, thus limiting the development of down jackets. [0003] Chinese patent CN200610154665.3 discloses a down jacket with a four-layer str...
