Description

Warm-keeping down feather leakage-proof down jacket

Technical Field

The invention relates to a warm-keeping down-proof down jacket.

Background

The existing down jacket mainly has two defects: leakage of lint and poor warmth retention. The down leakage is caused by that the needle holes at the sewing positions cannot be effectively closed, and the down can not be really and effectively prevented from being drilled out of the needle holes by the separation (grid) down filling technology; the poor warmth retention is due to the fact that the inner space of the area near the sewing line is narrow, down cannot be completely filled, a thin area is formed, and the warmth retention effect is seriously affected.

In order to solve the above problems, it is proposed to form a multi-layer cavity region by a weave design, for example, patent document CN107287736B discloses a three-dimensional fabric in which a surface layer weft yarn, an intermediate layer weft yarn, a back layer weft yarn and an intermediate layer weft yarn are interwoven to form a surface layer fabric, an intermediate layer fabric and a back layer fabric which are independent of each other, and a plurality of fillable pocket regions are formed. However, the problems such as change in the size of the grid and skewing of the weft tend to occur under the influence of tension and the like during finishing after dyeing. And the problems of difficult lattice matching, large material loss and the like exist when the lattice matching is needed during cutting.

For another example, patent document CN208708777U discloses a thermal down leakage prevention down jacket, which includes a jacket body, the jacket body includes an inner layer and an outer layer, the inner layer and the outer layer are sewn together through sewing parts, a down filling space is provided between the inner layer and the outer layer, a thermal strip is provided between the inner layer and the outer layer corresponding to the sewing parts, the inner layer and the outer layer are both provided with a nano silver antibacterial layer near the down filling space, the inner layer is a bamboo charcoal fiber layer, and the outer layer is compounded with a PU film. According to the down feather thermal insulation fabric, the inner layer and the outer layer are sewn or hot-melted together through the thermal insulation strips, so that the problem that the hollow space of down feather cannot be reserved due to too narrow combination parts of the fabric is solved, the thermal insulation effect is remarkably enhanced, the filled down feather is prevented from approaching to needle holes of the sewn parts, and the problem of down feather penetration is effectively solved; and the outer layer is compounded with the PU film, so that the down jacket can effectively prevent water and prolong the service life of the down jacket. However, the technology has the problems of complex manufacturing process and poor operability. And the foreign body feeling at the position of the heat-insulating strip is strong, and the wearing comfort is poor.

Detailed Description

The invention relates to a warm-keeping down-leakage-proof down jacket which comprises an outer layer, a middle layer and an inner layer, wherein the outer layer and the inner layer are respectively and alternately compounded with adhesive tapes on two sides of the middle layer to form a filling space, and down is filled in the filling space.

The alternate compounding mode is that firstly adhesive tapes are pasted on the inner layer garment pieces, then the middle layer is placed, then the adhesive tapes are pasted on the middle layer, the positions of the adhesive tapes above and below the middle layer are staggered, and then the non-symmetrical down filling cavity is formed by compounding on the hot melting machine. Wherein, the middle layer fills the fine hair chamber central point with outer formation and is corresponded to the adhesive tape laminating department of middle layer and inlayer, and the middle layer fills fine hair chamber central point with inlayer formation and is corresponded to middle layer and outer adhesive tape laminating department, forms complementary state, can promote cold-proof effect like this by a wide margin.

The adhesive tape distance refers to the distance between adjacent adhesive tapes on the same side, and can be equal distance or unequal distance, and is selected according to the requirement. Preferably, the distance between the rubber strips is 4-18 cm, and more preferably 5-12 cm. If the pitch of the rubber strips is too large, the filler may be unevenly filled and may be accumulated. If the pitch of the rubber strips is too small, the problem of difficulty in filling the pile may occur.

Preferably, the width of the strip is 3 to 8mm, more preferably 5 to 6 mm. If the adhesive tape is too wide, the wearer may feel a foreign body sensation and the comfort is poor, and the filling amount of down near the adhesive tape is small, so that the warmth retention tends to be reduced. If the adhesive tape is too narrow, the adhesion fastness may be impaired, and the peeling may be poor.

Preferably, the strip is in the shape of a straight line or an X. Wherein, the straight adhesive tape has stronger bonding fastness, and the bonding position of the appearance of the finished product is obviously separated. The bonding fastness of the X-shaped adhesive tape is slightly weak, and no obvious separation line exists at the appearance bonding position of the finished product. The two adhesive tapes can be respectively suitable for people with different appearance requirements.

The adhesive tape used here is specifically constructed with a fabric layer in the middle and hot-melt adhesive layers on both sides of the fabric layer. When the garment piece is used, the inner garment piece is placed on the template, two ends of the adhesive tape are attached to the double-faced adhesive tape points of the template at set intervals, then the middle garment piece is placed, the adhesive tape is attached to the double-faced adhesive tape points of the template at set intervals, and finally the outer garment piece is placed. Putting the cut pieces with the adhesive tapes and the template into a hot melting machine, heating and pressurizing the cut pieces, and dissolving the hot melting adhesive layer to enable the outer layer and the inner layer to be respectively compounded with the middle layer.

The type of the hot melt adhesive in the strip is not particularly limited, and may be a Polyurethane (PU) type, a Polyamide (PA) type, a Polyester (PES) type, a polyethylene (LOPE and HDPE) type, a PEA (polyester amide) type, or the like. When the adhesive tape is selected, the adhesive tape which is homologous with the resin film or the resin layer is selected as much as possible, so that the bonding fastness is stronger. Polyurethane (PU) systems are preferred.

Preferably, the resin film or resin layer is laminated on the inner side of the outer layer, so that the down jacket can be endowed with certain waterproofness, windproof performance, down-proof performance and warmth retention. Considering the air permeability and hand feeling of the finished product, the resin film is preferably a PU (polyurethane) resin film with the thickness of 10-18 μm. In consideration of the water resistance and the lint resistance of the finished product, the resin layer is preferably an AC (polyacrylate) resin layer having a thickness of 0.02 to 0.15 μm.

Preferably, the inner side of the inner layer is a calendered surface or a resin surface, so that the compounding fastness with the rubber strip can be enhanced, and the down resistance and the heat retention property are improved. The calendering surface is obtained by calendering one surface of a fabric under the conditions of a certain pressure, temperature and the like, and the calendering conditions are not particularly limited, but the pressure is preferably 15 to 25T, the temperature is preferably 160 to 190 ℃, and the speed is preferably 25 to 40 m/min. The resin surface here may be obtained by directly applying the resin to the fabric, or may be obtained by calendering the fabric and then applying the resin. In consideration of the water resistance and the lint resistance of the finished product, the resin layer is preferably an AC (polyacrylate) resin layer having a thickness of 0.02 to 0.15 μm.

In the present invention, the fiber material, structure, and the like of the outer layer, the intermediate layer, and the inner layer are not particularly limited. Preferably, the outer layer and the inner layer are plain woven with high density fabric made of nylon fiber or polyester fiber. The high-density woven fabric herein means a woven fabric having a density range of 190 warps/inch or more and 140 wefts/inch or more. The fabric used in the intermediate layer may be a relatively low-density fabric, as long as it can separate down, in consideration of cost and the like.

The invention solves the problems of the two-layer sewn product that the down penetration and the heat retention are poor, and simultaneously solves the problems of the three-layer seamless product that the cutting loss is large and the sewing is difficult to match.

The present invention will be further described with reference to examples and comparative examples.
